[0002] A wrench is a tool used to tighten or loosen nuts and bolts. It usually has an adjustable opening and is suitable for nuts or bolts of different sizes. A wrench is usually made of metal and comes in many types and sizes. Common ones include adjustable wrenches, fixed wrenches, open-end wrenches, etc. It is one of the most commonly used tools in repair and assembly work.

[0003] At present, there are many types of wrenches on the market, and the wrenches used by electricians need to have higher wrenches. Therefore, a wrench that is easy and safe to use is needed.

[0004] The existing wrenches that are easy to use safely have certain disadvantages when used. When the existing wrenches that are easy to use safely are used, the wrenches used by electricians are usually covered with an insulating sleeve on the outside to prevent electricians from getting electric shock when using the wrenches. However, the structure is simple. When in use, if the material of the insulating sleeve is poor, the insulating effect of the insulating wrench is poor, thereby increasing the probability of electric shock when the electrician uses the insulating wrench, and cannot meet people's needs.
