Description

Technical Field

[0001] This utility model relates to the field of mechanical structure design and mechanical application technology, specifically to a fitter's wrench. Background Technology

[0002] As a type of work that is primarily manual, fitter work requires adapting to complex environmental conditions (such as changes in temperature and humidity, mechanical vibration, etc.) in workshops or factories, and frequently operating various metal processing equipment. The work environment places high demands on the flexibility, safety, and versatility of the tools used.

[0003] Traditional wrenches generally suffer from significant drawbacks: First, their fixed size design leads to poor compatibility with nuts / bolts of different sizes, requiring frequent tool changes and severely impacting work efficiency. Second, their limited functionality and rigid mechanical structure make them incompatible with non-standard fasteners, and they pose safety hazards such as slippage and breakage during operation. As industrial manufacturing moves towards higher efficiency and precision, the industry urgently needs a wrench tool that integrates torque adjustment, size self-adaptation, and overload protection to address the pain points of insufficient compatibility and high operational risks inherent in traditional technologies. This would improve assembly quality, reduce tool management costs, and ensure operational safety. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a fitter's wrench that is highly versatile and can improve operational efficiency.

[0005] To achieve the above objectives, this utility model provides a fitter's wrench, comprising:

[0006] A sleeve, wherein the inner wall of the sleeve is polygonal;

[0007] A handle is fixedly connected to the sleeve and is used to rotate the sleeve after the sleeve is fitted onto the bolt. The handle has a cavity inside.

[0008] An adjustment mechanism, located within the cavity, is used to adjust the distance between one side of the inner wall of the sleeve and the center of the sleeve.

[0009] Optionally, the adjustment mechanism includes:

[0010] The first threaded rod has a threaded hole at the end of the handle away from the sleeve, and the first threaded rod is connected to the handle through the threaded hole at the end of the handle away from the sleeve.
