Description

Sleeve Fixing Tools

Technical Field

The present invention relates to a tool for driving a fastener, and more particularly to a sleeve fastening tool.

Background technique

As the times progress, the tools used are becoming more advanced and more diverse. Since some machines have higher requirements for the locking degree of screws and bolts, some screws and bolts cannot be locked or unlocked or disassembled without the use of tools.

Since many machines are used for many years after assembly before they need to be disassembled for repair or replacement of parts, the bolts are easily rusted or damaged due to various external factors, which makes the bolts difficult to disassemble with the original tools. At the same time, due to the rust or damage of the bolts, they are easily deformed or damaged (known as tooth collapse in the industry) when being disassembled or assembled.

In addition, with the continuous updating of technology, in order to make the tightening, locking and removal of screws and bolts easier and faster, various air-powered or electric-powered tools have been invented and circulated on the market. Such tools are very effective in tightening and removing screws and bolts, and can greatly reduce the time and effort of manpower.

However, although electric tools or pneumatic tools have higher force and speed efficiency in tightening and removing screws and bolts than human labor, they are much worse than human labor in terms of force control. It often happens that they stop too late, resulting in excessive force to tighten the bolts or forcibly turning the tightened bolts, causing broken teeth. In the case of broken bolts, the common and commonly used method is to directly cut off the bolts or the entire set of screws and reinstall them. In addition, even if the degree of broken teeth is relatively small, it is necessary to use a tool with a smaller aperture to try to unscrew it, causing considerable trouble to the user.

Therefore, there is indeed a problem that users encounter troubles and time-consuming problems when they encounter broken bolts, which affects the efficiency of users' work.

Summary of the invention

The main purpose of the present invention is to provide a sleeve fixing tool, which includes a main body, which includes a driving section and a sleeve fixing section connected to each other, and the sleeve fixing section includes an outer ring surface and a fixing groove.
