[0031] The first joining portion 312 and the second joining portion
322 are capable of being joined with each other. In the illustrated
embodiment, an outer diameter smaller of the first annular side
wall 314 can be smaller than an outer diameter of the second
annular side wall 324. When the first joining portion 312 and the
second joining portion 322 are joined with each other, the first
annular side wall 314 is located inside the second annular side
wall 324. Furthermore, the outer diameter of the first annular side
wall 314 may be about equal to an inner diameter of the second
annular side wall 324, so that the first annular side wall 314 and
the second annular side wall 324 can be joined with each other by
interference fit. However, the manner to assemble the first annular
side wall 314 with the second annular side wall 324 is not limited

can be identical.
[0032] The fixing ring 330 wraps the first joining portion 312 and
the second joining portion 322 which are joined with each other.
Specifically, an annular groove 334 is defined in an inner wall 332
of the fixing ring 330 for receiving the first joining portion 312
and the second joining portion 322 which are joined with each
other. In other words, the joined first and second joining portions
312, 322 are retained in the annular groove 334. In the illustrated
embodiment, the fixing ring 330 has elasticity and can be made of
plastic, rubber, or other elastic materials. The fixing ring 330
can be integrally formed from a monolithic material. In another
embodiment, the fixing ring 330 can be formed by combining multiple
elements. In another embodiment, the fixing ring 330 can have no
elasticity.
[0033] The rotating device 210 includes a rotating shaft 211, an
annular wrapping element 212 and a rotating ring 213. Two ends of
the rotating shaft 211 are, for example, installed between the
first annular bottom wall 313 and the second annular bottom wall
323, while the annular wrapping element 212 surrounds a portion of
the rotating shaft 211. The rotating device 210, for example, is
provided with a plurality of vanes 214. The rotating ring 213
surrounds the rotating shaft 211 and has two opposite shaft holes
213a. The two ends of the rotating shaft 211 are inserted into the
two shaft holes 213a of the rotating ring 213, respectively.
Additionally, the rotating shaft 211 and the annular wrapping
element 212 can be integrated into one piece. The material for the
rotating shaft 211 and the annular wrapping element 212 can,
without limitation, be metal such as zinc alloy. In other
embodiments, the rotating shaft 211 and the annular wrapping
element 212 can be formed separately and then combined to each
other.
[0034] The illustrated twist exercising device 200 can further
include a first annular track 220 and a second annular track 230.
The first annular track 220 is disposed at the first annular bottom
wall 313, the second annular track 230 is disposed at the second
annular bottom wall 323, and the two ends of the rotating shaft 211
are disposed between the first annular track 220 and the second
annular track 230. Specifically, the two ends of the rotating shaft
211 are leant on the first annular track 220 and the second annular
track 230. The first annular track 220 and the second annular track
230 are made from such a material as to enable the first and second
annular tracks 220, 230 to have a sufficient friction coefficient
relative to the rotating shaft 211, so that the rotating shaft 211
can rotate relative to the first and second annular tracks 220,
230. For example, the first and second annular tracks 220, 230 can,
without limitation, be made of plastic or rubber.
[0035] In another embodiment, when the first and second covers 310,
320 are made from such a material as to enable the first and second
annular bottom walls 313, 323 to have a sufficient friction
coefficient relative to the two ends of the rotating shaft 211 so
that the rotating shaft 211 can rotate, the two ends of the
rotating shaft 211 can be directly leant on the first and second
annular bottom walls 313, 323. Therefore, the first and second
annular tracks 220, 230 can be omitted. For example, when the first
and second covers 310, 320 are made of plastic, the two ends of the
rotating shaft 211 can be directly leant on the first and second
annular bottom walls 313, 323.
[0036] In the illustrated twist exercising device 200, the first
and second joining portions 312, 322 extend outside from the first
and second covers 310, 320 of the housing 300, respectively. After
the first and second joining portions 312, 322 are joined with each
other, the joined first and second joining portions 312, 322 can as
a whole be served as a holding part for the user to hold the twist
exercising device 200, thereby reducing the risk of the twist
exercising device 200 falling off from the palm of the user.
Furthermore, since threads are not required to be formed on the
first and second covers 310, 320, a thickness of each of the first
and second covers 310, 320 can be significantly reduced, thereby
reducing the material cost and the weight of the housing 300. Thus,
the illustrated twist exercising device 200 has the advantages of
low cost and light weight.
[0037] In order to render the user to know the number of
revolutions of the rotating device 210 in the housing 300, the
twist exercising device 200 can further include a counter 240. The
counter 240 is, for example, disposed at one side of the second
cover 320 opposite to the second opening end 321. That is, the
counter 240 is disposed at the second bottom wall 325 of the second
cover 320. In the embodiment wherein the second bottom wall 325 is
defined with the opening 327, the counter 240 can be disposed in
the opening 327. In another embodiment, the counter 240 is, for
example, disposed at one side of the first cover 310 opposite to
the first opening end 311. That is, the counter 240 is disposed at
the first bottom wall 315 of the first cover 310. In the embodiment
wherein the first bottom wall 315 is defined with the opening 317,
the counter 240 can be disposed in the opening 317.
[0038] Except for the counter 240, the rotating device 210 further
includes a signal emitter 215, wherein the signal emitter 215 is
attached to the annular wrapping element 212 and configured to
provide signals to the counter 240. When the rotating device 210
rotates, the signal emitter 215 rotates with the rotating device
210, and the counter 240 counts the number of resolutions of the
rotating device 210 according to the variation of the sensed
signal. In the illustrated embodiment, the signal emitter 215 is,
for example, a magnet unit, and the counter 240 is capable of
sensing magnetic signals. The magnet unit includes, for example, a
fixing tube 251 and a magnet 252 disposed in the fixing tube
251.
[0039] FIG. 4 is a three-dimensional view of the rotating shaft and
the annular wrapping element according to an embodiment of the
present invention. FIG. 5 is a schematic diagram showing the signal
emitter which is mounted in the annular wrapping element according
to an embodiment of the present invention. Referring to FIG. 3 to
FIG. 5, the annular wrapping element 212 is, for example, defined
with a mounting hole 216. The rotating shaft, for example, has an
annular inner wall 217. The annular inner wall 217 is defined with
a notch 218. The notch 218 is communicated with the mounting hole
216 so that the mounting hole 216 is exposed. The notch 218 is
provided with at least an abutting portion 219, wherein two
abutting portions 218 are provided in the notch 218 in the
illustrated embodiment. However, the number of the abutting portion
219 is not limited in the present invention. The fixing tube 251 of
the signal emitter 215 is disposed into the mounting hole 216 via
the notch 218 under the direction E shown in FIG. 5. The fixing
tube 251 is, for example, provided with at least an elastic pillar
protruding out of the mounting hole 216. Each elastic pillar 253
corresponds to and abuts against one abutting portion 219, so that
the fixing tube 251 is avoided from dropping off from the mounting
hole 216. Furthermore, the mounting hole 216 is, for example, a
through hole in the illustrated embodiment. In order to prevent the
fixing tube 251 from dropping outside the annular wrapping element
212 from the mounting hole 216, the fixing tube 251 can further be
provided with at least a stopping block 254 protruding out of the
mounting hole 216, wherein two opposite stopping blocks 254 are
provided on the fixing tube 251 in FIG. 3 as an example. Each
stopping block 254 interferes with the annular wrapping element 212
and thus cannot be inserted into the mounting hole 216, thereby
preventing the fixing tube 251 from dropping outside the annular
wrapping element 212 from the mounting hole 216.
[0040] It should be pointed out that the stopping block 254 is not
a necessary part of the fixing tube 251. In another embodiment, the
diameter of the mounting hole 216 can be gradually reduced from an
inner side to an outer side of the annular wrapping element 212 to
cause the diameter of the mounting hole 216 at the outer side of
the annular wrapping element 212 to be smaller than a diameter of
the fixing tube 251, thereby preventing the fixing tube 251 from
dropping outside the annular wrapping element 212 from the mounting
hole 216. In another embodiment, an inner surface of the mounting
hole 216 can be provided with an abutting portion. Due to the
abutting portion, the fixing tube 251 is prevented from dropping
outside the annular wrapping element 212 from the mounting hole
216. In yet another embodiment, the mounting hole 216 is a blind
hole to accordingly prevent the fixing tube 251 from dropping
