[0002] A screwdriver bit is a part of an electric or hand tool used to tighten or loosen screws. It can be divided into many types according to the head shape, such as flat head, Phillips head, Pozidriv head, square head, hexagonal head, etc.

[0003] In actual use, the screwdriver bit needs to be plugged into an electric drill, a handle or other tool to form a screwdriver bit tool for loosening and tightening screws. However, the traditional screwdriver bit tool only relies on the nesting of the tail end of the screwdriver bit with the tool with a polygonal structure to achieve axial rotational positioning of the screwdriver bit and the tool. This axial rotational positioning method is prone to failure due to deformation of the corners of the tail end of the screwdriver bit caused by excessive force on the screwdriver bit, which eventually causes the screwdriver bit to slip, affecting the normal use of the screwdriver bit tool. For this reason, the present application proposes a reinforced screwdriver bit tool set. Utility Model Content
