Description

Screw removal tool

This creation is about a screw removal tool that can adjust the distance between the outside and the inside of the jaws to match the screws of different sizes to facilitate the removal of the screws.

Pressing, the screw that is generally used to lock on the implement or the object is often deformed or worn by the outer wall surface of the screw head or the nut due to the multiple rotation of the wrench or the clamp (generally called the sliding tooth). Therefore, the tool cannot be firmly clamped to the screw head or the nut, and the screw cannot be smoothly unscrewed, and when the screw is removed by the wrench or the clamp, the space in the position where the screw is locked is often narrow. It is very inconvenient to remove the screws, and it is very inconvenient to remove the screws. In addition, in order to use the screw heads or nuts of different sizes, various wrenches and disassembly tools of different sizes must be prepared, and the tool purchase cost is high and the carrying is inconvenient.

For the purpose of achieving the above-mentioned purpose and effect of the above-mentioned use, a preferred and feasible embodiment will be described, and the details are as follows:

For the embodiment of the present invention, please refer to the first to third figures, which mainly includes: a grip bar 1 , one end of the grip bar 1 is provided with a plug portion 10 , and the plug portion 10 is nine with the rod body a ten-degree bend, the plug portion 10 is a polygonal body, the wall portion of the plug portion 10 is provided with a positioning steel ball 11, the rod of the grip 1 is provided with a non-slip pattern 12;
An adjusting member 2 is connected to the insertion portion 10 of the gripping rod 1. A connecting seat 20 is protruded from a side of the adjusting member 2, and a polygonal insertion hole 21 is defined in the connecting seat 20. The outer peripheral surface of the adjusting member 2 is provided with a non-slip groove 22, and the middle portion of the other side of the adjusting member 2 is provided with a groove 23, and the outer peripheral surface of the groove 23 is equidistantly provided with at least three curved guiding grooves 24, a through hole 25 is formed in the recess 23 through the insertion hole 21, and a screwing member 26 is disposed in the insertion hole 21 and the through hole 25;
A fixing member 3 is disposed on the outer side of the adjusting member 2, and a convex body 30 is disposed on one side of the fixing member 3, and the protruding body 30 is disposed in the recess 23 of the adjusting member 2, and the convex portion The body 30 is provided with a screw hole 31 for screwing the screwing member 26, and at least three positioning guide grooves 32 are equally divided on one side of the fixing member 3, and the other side of the fixing member 3 corresponds to the at least Each of the three positioning guide grooves 32 is provided with a sliding slot 33;
At least three clamping jaws 4 are respectively disposed on at least three sliding slots 33 of the fixing member 3, and one end of the clamping jaws 4 is provided with a slider 40, and the positioning guides 41 are respectively disposed on opposite sides of the slider 40. The positioning guide 41 is disposed in the positioning guide 32 of the fixing member 3. The end surface of the slider 40 of the clamping jaw 4 is provided with an insertion hole 42. The insertion hole 42 defines a guiding post 43. The outer end of the guide post 43 is embedded in the arcuate guide groove 24 of the adjusting member 2, and the outer wall surface of the front end of the clamping jaw 4 is a tapered surface 44, and the inner wall surface is a clamping end 45. So, it is a screw removal tool.

When assembling, please refer to the first to third figures. First, at least three guiding columns 43 are respectively inserted into the insertion holes 42 of at least three clamping jaws 4, and then the at least three clamping jaws 4 are respectively fixed and fixed. The at least three sliding slots 33 of the member 3 are disposed in the positioning guides 32 of the fixing member 3, and the at least three clamping jaws 4 are disposed on the fixing member 3. The sliding groove 33 is moved inward or outward in a straight line, and the fixing member 3 is disposed on the side of the adjusting member 2, and the convex body 30 of the fixing member 3 is disposed in the groove of the adjusting member 2. The guide posts 43 of the at least three jaws 4 are respectively disposed in the arcuate guide grooves 24 of the adjusting member 2, and then the screwing member 26 is inserted into the insertion hole 21 of the adjusting member 2 and The inside of the through hole 25 is screwed into the screw hole 31 of the fixing member 3, and the adjusting member 2, the fixing member 3 and the at least three clamping jaws 4 are assembled by the screw lock of the screwing member 26, and then the gripping rod is assembled. The insertion portion 10 of the insertion member 10 is inserted into the insertion hole 21 of the adjusting member 2, so that the positioning steel ball 11 on the insertion portion 10 of the gripping rod 1 is elastically resisted against the inner wall surface of the insertion hole 21 of the adjusting member 2.
