The utility model relates to a wrench, in particular to a disassembly wrench without tooth marks.

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. Wrenches are usually provided with openings or sleeve holes for clamping bolts or nuts at one or both ends of the handle. When using an external force on the handle along the thread rotation direction, the bolts or nuts can be twisted. The currently used wrenches are used for a long time. If not, tooth marks will be left on the clamping part, affecting the use of the wrench, and the clamping part cannot be replaced, resulting in waste of resources.
