Problems solved by technology

[0003] Generally, under long-term use of hexagonal screws, the inner hole of the hexagonal screw will be rounded. The rounded screw will make it difficult to move the hexagonal wrench. The screw is taken out by the method, so that the inner hole of the screw is damaged and can no longer be used, and a new screw must be prepared. However, for some designed screws, it is difficult for the general public to find suitable screws.
[0004] Furthermore, the rounded screw is easy to cause damage to the workpiece, because the hexagonal wrench cannot resist the inner hole of the screw, causing the wrench to slip and easily wear and damage the inner hole of the screw
In addition, the inner hole of the screw is also prone to rust and the hexagonal wrench cannot be pulled smoothly.

Embodiment Construction

[0048] Regarding the technology, means and effects used in the present invention, a preferred embodiment is given and described in detail below with drawings, which are for illustration purposes only, and are not limited by this structure in the patent application.

[0049] refer to Figure 1 to Figure 3 , is a three-dimensional appearance view and a three-dimensional exploded view of the screw remover of the present invention. The present invention includes a body 10, a pressing member 20 and a control member 30, the pressing member 20 is passed through the body 10, the control member 30 is connected to the pressing member 20, The displacement of the pressing member 20 relative to the main body 10 is controlled so that the pressing member 20 presses the main body 10 to expand.

[0050] Also refer to Figure 4 as well as Figure 5 , the body 10 has a driving end 11 and a connecting end 12, the driving end 11 is integrally connected with the connecting end 12, the driving end ...

Abstract

The invention discloses a screw remover which comprises a body, a pressing part and a control part, wherein the body is provided with a driving end and a connecting end; a plurality of cut grooves are arranged at the driving end radially; a through groove is arranged on the body axially; the head part of the pressing part is provided with a guiding surface; the guiding surface can press the innerperiphery of the through groove; the control part is connected with the pressing part and the connecting end of the body; the control part can move between two positions, when the control part moves to the first position, the guiding surface does not press the inner periphery of the through groove, and when moving to the second position, the control part drives the pressing part to move towards the direction opposite to the driving end to enable the guiding surface of the pressing part to press the inner periphery of the through groove so as to enable the driving end of the body to expand outwards.

Description

technical field [0001] The invention relates to a tool for removing screws, in particular to a screw remover in which the driving end of the body expands outwards against the inner hole of the screw. Background technique [0002] A general hexagonal wrench is designed for different sizes, and several different sizes form a tool set of a hexagonal wrench to drive various sizes of hexagonal socket head screws. [0003] Generally, under long-term use of hexagonal screws, the inner hole of the hexagonal screw will be rounded. The rounded screw will make it difficult to move the hexagonal wrench. The screw is taken out by the method, so that the inner hole of the screw is damaged and can no longer be used, and a new screw must be prepared. However, for some designed screws, it is difficult for the general public to find suitable screws. [0004] Furthermore, the rounded screw is likely to cause damage to the workpiece, because the hexagonal wrench cannot resist the inner hole of...
