Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a Continuation-in-part Application of
Ser. No. 11/556,036, filed 14 Jan. 2011, and entitled "ADJUSTABLE
SCRAPER", now pending.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a scraper, and more
particularly to an adjustable and replaceable scraper.
[0004] 2. Description of Related Art
[0005] A conventional scraper has a scarping blade extending form a
front thereof. However, the conventional scraper is discarded when
the scraping blade is consumed. It is inconvenient and wasted.
[0006] Another conventional scraper has a replaceable blade. When
the blade is consumed, the blade can be replaced to a new one.
However, the connection between the blade and the conventional
scraper is weak. Therefore, the conventional scraper is easily
broken.
[0007] The present invention has arisen to mitigate and/or obviate
the disadvantages of the conventional scraper.
SUMMARY OF THE INVENTION
[0008] The main objective of the present invention is to provide an
improved scraper, and more particular to an adjustable and
replaceable scraper.
[0009] To achieve the objective, the adjustable and replaceable
scraper in accordance with the present invention includes a handle,
an extender movably mounted in the handle, a replaceable blade
mounted on the extender. The handle has an elongated slot defined
therein and extending along an axis thereof. The handle has a
through hole defined in a top side thereof and extending through a
bottom side thereof. The through hole is communicated with the
elongated slot. The extender is movably inserted into the elongated
slot in the handle. The extender has a body and a head extending
from the body. The body has multiple positioning holes defined
therein and passing therethrough. The body has a groove defined
therein and passing therethrough. The groove is disposed along a
length of the body and communicated with the positioning holes.
Each positioning hole has a diameter greater than a width of the
groove. The head of the extender has a width grater than that of
the body. The head has two blockers respectively extending from two
laterals thereof. The head has a screw hole defined therein and
passing therethrough. A holder is mounted on the head of the
extender. The holder has a body and a head extending from the body.
The head of the holder corresponds to the head of the extender such
that a width of the head of the holder is equal to that of the head
of the extender. The head of the holder is confined by the two
blockers of the extender for preventing the head of the holder
sliding relative to the extender. The replaceable blade is
sandwiched between the head of the extender and the head of the
holder. The replaceable blade is also confined by two blockers for
preventing the replaceable blade sliding relative to the extender.
A screw passes through the head of the holder, the replaceable
blade, and screws into the screw hole in the head of the extender.
A button is mounted on the top side of the handle and partially
passes through the through hole. The button has a rod extending
therefrom. The rod has a diameter substantially equal to the width
of the groove. A spring is compressively received in through hole
and passed by the rod. A stopper is mounted on the bottom side of
the handle. The stopper has a tube extending therefrom for
partially receiving the rod of the button. The stopper has a
shoulder annularly disposed on the tube for selectively engaging
with the positioning holes. The shoulder has a diameter
substantially equal to that of each positioning hole.
[0010] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Referring to the drawings and initially to FIGS. 1-7, an
adjustable and replaceable scraper in accordance with the present
invention comprises a handle 10, an extender 24 movably mounted in
the handle 10, a replaceable blade 30 mounted on the extender
24.
[0017] The handle 10 has an elongated slot 120 defined therein and
extending along an axis thereof. The handle 10 has a through hole
122 defined in a top side thereof and extending through a bottom
side thereof. The through hole 122 is communicated with the
elongated slot 120.
[0018] The extender 24 is movably inserted into the elongated slot
120 in the handle 10. The extender 24 has a body 242 and a head 241
extending from the body 242. The body 242 has multiple positioning
holes 244 defined therein and passing therethrough. The body 242
has a groove 243 defined therein and passing therethrough. The
groove 243 is disposed along a length of the body 242 and
communicated with the positioning holes 244. Each positioning hole
244 has a diameter greater than a width of the groove 243. The head
241 of the extender 24 has a width grater than that of the body
242. The head 241 has two blockers 25 respectively extending from
two laterals thereof. The head 241 has a screw hole 27 defined
therein and passing therethrough.
[0019] A holder 22 is mounted on the head 241 of the extender 24.
The holder 22 has a body 222 and a head 221 extending from the body
222. The head 221 of the holder 22 corresponds to the head 241 of
the extender 24 such that a width of the head 221 of the holder 22
is equal to that of the head 241 of the extender 24. The head 221
of the holder 22 is confined by the two blockers 25 of the extender
24 for preventing the head 221 of the holder 22 sliding relative to
the extender 24. The replaceable blade 30 is sandwiched between the
head 241 of the extender 24 and the head 221 of the holder 22. The
replaceable blade 30 is also confined by two blockers 25 for
preventing the replaceable blade 30 sliding relative to the
extender 24. A screw 28 passes through the head 221 of the holder
22, the replaceable blade 30, and screws into the screw hole 27 in
the head 241 of the extender 24.
[0020] A button 124 is mounted on the top side of the handle 10 and
partially passes through the through hole 122. The button 124 has a
rod 125 extending therefrom. The rod 125 has a diameter
substantially equal to the width of the groove 243. A spring 126 is
compressively received in through hole 122 and passed by the rod
125.
[0021] A stopper 128 is mounted on the bottom side of the handle
10. The stopper 128 has a tube 129 extending therefrom for
partially receiving the rod 125 of the button 124. The stopper 128
has a shoulder 127 annularly disposed on the tube 129 for
selectively engaging with the positioning holes 244. The shoulder
127 has a diameter substantially equal to that of each positioning
hole 244.
[0022] Referring to FIGS. 3-7, the replaceable blade 30 is fixed
between the holder 22 and the extender 24. When the replaceable
blade 30 is consumed, the original replaceable blade 30 can be
easily replaced to a new one. When the shoulder 127 of the stopper
128 is engaged with one of the positioning holes 244, the extender
24 is fixed in the handle 10. When the button 124 is pressed and
the spring 126 is compressed, the shoulder 127 is disengaged from
the positioning hole 244 and the rod 125 of the button 124 is
disposed in the groove 243, such that the rod 125 is able to slide
in the groove 243 and the extender 24 is able to adjust a distance
relative the handle 10. When the rod 125 is move in another
positioning hole 244 and the button 124 is released, the spring 126
pushes the button 124 back and the shoulder 127 is engaged with
another positioning hole 244 for fixing the extender 24 relative to
the handle 10.
[0023] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.
