technical field

The utility model relates to the technical field of assembly and disassembly tools, in particular to a assembly and disassembly tool for lock nuts.

Background technique

A wrench is a commonly used installation and removal tool. Hand tools for turning bolts, screws, nuts, and other open or socketed fasteners whose threads hold bolts or nuts tightly by the principle of leverage. The wrench is usually formed with a clamping handle at one or both ends of the handle to apply an external force to the handle to twist the bolt or nut to hold the opening or sleeve of the bolt or nut. When in use, an external force is applied to the shank in the direction of thread rotation, so that the bolt or nut can be twisted.

In the existing method of removing lock nuts for vehicle maintenance, the main operator holds a chisel in his left hand and aligns it with the concave teeth of the lock nut, and uses a hammer in his right hand to hit the chisel, and the lock nut is rotated along the thread loosening direction through the impact force, thereby completing the process. The loosening operation of the lock nut will easily cause greater damage to the teeth of the lock nut when disassembling and assembling the lock nut. It will cause the lock nut to crack and be scrapped.
