Description
FIELD OF THE INVENTION
[0001] The present invention relates to a packing tool, and more
particularly to a packing tool capable of displaying tension.
BACKGROUND OF THE INVENTION
[0002] In general, a packing strap is used to pack goods for
transportation by means of a packing tool. A conventional packing
tool comprises a body. The body is provided with a strap cutting
device, a strap winding device and a strap pressing device. The
strap winding device is provided with a handle. One end of the
packing strap is inserted into the strap pressing device, and the
other end of the packing strap is inserted through the strap
cutting device and wound around the strap winding device and
gradually tightened by the handle. Finally, the unnecessary packing
strap is cut by the strap cutting device to complete the packing
operation.
[0003] However, during the process of tightening the packing strap
by the handle, if the tension applied to the packing strap is too
large, the packing strap will exert a reaction force to the strap
winding device, making the handle stuck and unable to rotate. As a
result, the packing tool suffers a lot of wear and tear and even
malfunctions. Conversely, if the tension applied to the packing
strap is insufficient, the strap winding device is unable to
tighten the goods. At this time, it is required to cut the packing
strap by using the strap cutting device, and then perform the
packing operation again. Therefore, the packing tool cannot achieve
the effect of fast packing. Accordingly, the inventor of the
present invention has devoted himself based on his many years of
practical experiences to solve these problems.
SUMMARY OF THE INVENTION
[0004] The primary object of the present invention is to provide a
packing tool capable of displaying tension, which allows the user
to pay attention to the tension value applied to a packing strap by
the packing tool at any time, so as to achieve the purpose of fast
packing.
[0005] In order to achieve the above object, a packing tool capable
of displaying tension is provided. The packing tool comprises a
body, a detection unit, and a display unit. The body includes a
strap winding device. The detection unit is connected to the strap
winding unit. The detection unit is configured to detect a tension
value of the strap winding device. The display unit is electrically
connected to the detection unit for displaying the tension
value.
[0006] In the packing tool provided by the present invention, the
detection unit is used to detect the applied force value of the
strap winding device and then calculate and output a tension value
to the display unit, so that the user can pay attention to the
tension value applied to the packing strap by the packing tool at
any time through the display unit, so as to achieve the purpose of
fast packing.

72 will light up.
[0024] The wireless communication unit 80 is electrically connected
to the processing unit 40. The wireless communication unit 80 is
Bluetooth. The value detected by the detection unit 20 or the
tension value corrected by the processing unit 40 are transmitted
to a mobile device, such as a mobile phone, in real time, which
allows the user to pay attention to the tension value applied to
the packing strap by the packing tool 10 at any time. The wireless
communication unit 80 is electrically connected to a third
light-emitting member 81. The third light-emitting member 81 is an

The second button 62 and the third button 63 are used to adjust the
first warning value and the second warning value, and finally
return to the real-time display mode to complete the setting
steps.
[0027] FIG. 8 and FIG. 9 are schematic views of the use of the
preferred embodiment of the present invention. When in use, after a
packing strap is used to pack an article, the strap pressing device
13 is used to press against the packing strap, and the packing
strap is inserted through the winding mandrel 111. Next, the handle
14 is lifted up, and the first abutting member 16 is abutted
against the ratchet gear 15 so as to drive the ratchet gear 15 to
rotate the winding mandrel 111 and roll the packing strap. When the
handle 14 is pulled back, the second abutting member 17 is abutted
against the ratchet gear 15 and the first abutting member 16 is
disengaged from the ratchet gear 15, so that the user can restore
the angle of the applied force of the handle 14 and further tighten
the strap.
[0028] When the packing strap is tightened to a certain degree, the
tension of the packing strap will generate a reaction force on the
strap winding device 11 to deform the first abutting member 16. At
this time, the detection unit 20 will detect the amount of
deformation of the first abutting member 16, and the processing
unit 40 receives the signal from the detection unit 20 and then
calculates and outputs the tension value to the display unit 50.
The panel 51 is located at a relative position to the underside 141
of the handle 14, so a tension value will be displayed when the
handle 14 is operated. The user can pay attention to the tension
value applied to the packing strap by the packing tool 10 at any
time through the panel 51 to cooperate with the following module
42. Alternatively, the peak of the tension value can be displayed
through the peak module 44, and the unit of force can be changed by
using the conversion module 43.
[0029] It is worth mentioning that the user can set the first
warning value and the second warning value at any time through the
input unit 60 and the warning module 45. The first warning value
and the second warning value are the target values of tension. When
the tension value reaches the first warning value, the first
light-emitting member 71 will light up, that is, the set target
value has been reached, and the strap cutting device 12 can be used
to complete the packing operation. When the tension value reaches
the second warning value, the second light-emitting member 72 will
light up, that is, the set target value has been reached, and the
strap winding device 11 should be stopped to avoid excessive
tension. In this way, the user can learn whether the tension value
applied to the packing strap by the packing tool 10 has reached or
exceeded the target value, thereby judging the tension value of the
packing strap quickly.
[0030] Although particular embodiments of the present invention
have been described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the present invention. Accordingly, the
present invention is not to be limited except as by the appended
claims.
