Abstract

A scraper includes a cover, a first clamping member, a second clamping member, and a locking device. The cover has a connection portion and an insertion protrusion. The first clamping member has a first through groove, and the second clamping member has a second through groove. The locking device has a sliding portion slidably arranged in the first through groove and the second through groove. The connection portion of the cover is detachably connected to the side of the first clamping member opposite to the second clamping member, and the insertion protrusion inserts through the first through groove and the second through groove and is detachably coupled with the second clamping member.

First claim

The invention claimed is:

1. A scraper comprising:
a cover having a connection portion and an insertion protrusion;
a first clamping member having a first clamping portion, a first connecting portion, and a first through groove disposed between the first clamping portion and the first connecting portion;
a second clamping member having a second clamping portion, a second connecting portion, and a second through groove disposed between the second clamping portion and the second connecting portion, wherein the second connecting portion is pivotally connected to the first connecting portion; and
a locking device having a first abutting portion abutting against a side of the first clamping member opposite to the second clamping member, a second abutting portion abutting against a side of the second clamping member opposite to the first clamping member, and a sliding portion having an end connected to the first abutting portion and another end connected to the second abutting portion, and wherein the sliding portion is slidably arranged in the first through groove and the second through groove;
wherein the connection portion of the cover is detachably connected to the side of the first clamping member opposite to the second clamping member, and wherein the insertion protrusion inserts through the first through groove and the second through groove and is detachably coupled with the second clamping member.

2. The scraper as claimed in claim 1 , wherein the insertion protrusion includes an insertion section and a hook section, wherein the insertion section is flexible and connected to the connection portion, and wherein the hook section extends from the insertion section and is detachably coupled with the second clamping member.

3. The scraper as claimed in claim 2 , wherein the cover has a back portion opposite to the connection portion, and at least one clamping arm including a curved section and a clamping section, wherein the curved section is flexible and connected to the back portion, wherein the clamping section is connected to an end of the curved section opposite to the back portion, and wherein a blade storage compartment is formed between the back portion and the clamping section.

4. The scraper as claimed in claim 3 , wherein the cover defines a front end and a rear end, wherein the numbers of the at least one clamping arm is two, and each of the two clamping arms is disposed between the front end and the rear end, and wherein the clamping sections of the two clamping arms are parallel to each other and extend towards the front end.

5. The scraper as claimed in claim 4 , wherein the cover further defines a left side and a right side, and wherein the back portion is provided with two lateral limiting protrusions respectively extending opposite to the connection portion and disposed adjacent to the left side and the right side.

6. The scraper as claimed in claim 4 , wherein the connection portion is provided with a front limiting protrusion extending opposite to the back portion and disposed adjacent to the front end, and wherein the front limiting protrusion is connected to a front reverse hook extending from one end of the front limiting protrusion and towards the rear end.

7. The scraper as claimed in claim 6 , wherein the two clamping arms, the two lateral limiting protrusions, the insertion protrusion and the front limiting protrusion are integrally formed in the cover as a monolithic structure, and wherein the two lateral limiting protrusions is flexible to change a distance between each other.
