Problems solved by technology

[0003] Screwdrivers can be divided into straight, cross, rice, star, square, hexagonal, Y-shaped heads, etc. according to different head shapes, but they all work by turning the handle connected to the cutter head. The cutter head is usually set at the end of the cutter head in a cylindrical shape. When the screw being turned is too tight, it takes a lot of force to turn the handle, which makes the rotation inconvenient and easy to slip
