Problems solved by technology

[0002] Traditional manual tool handles use wooden handles and plastic handles to realize flipping with small and large heads, which has the following problems: 1. Since the small end of the handle is inserted into the tool hole, the small end is easy to fall off from the hand during use; 2. Because the wooden handle and the plastic handle are matched with the tool hole, it is difficult to achieve the pulling force of the professional safety standard, and the tool head will fall off and loosen during use, which will bring safety hazards
