Description

Technical Field

[0001] The utility model relates to the technical field of disassembling wrench racks, in particular to a wrench rack which is anti-falling and anti-smashing and hand-knocking. Background Art

[0002] As an installation and disassembly tool, the percussion wrench is widely used in enterprise production. When using a percussion wrench, one person usually holds the wrench and inserts the wrench into the nut at one end, while the other person holds the percussion wrench with one hand and inserts it into the nut at the other end, and uses a hammer with the other hand to hit the percussion wrench to tighten or loosen the bolt. At present, there are the following safety hazards in the use of percussion wrenches: 1. If the wrench is not held properly, excessive force is used during the percussion wrench, and the wrench will fly off the bolt and injure the staff; 2. When holding the wrench and using a hammer to hit the tail of the wrench, if the staff is not skilled, the hammer will directly hit the hand and cause an accident; 3. When it comes to high-altitude operations, the wrench falling off may also cause high-altitude falling objects to injure people. In addition, the percussion wrench is used in conjunction with the force sleeve. Because the force sleeve requires a length, it cannot be used due to limited space in some places, resulting in inconvenient operation. Summary of the invention
