Description

Technical Field

[0001] This utility model relates to the field of anti-loosening bolt bits, and in particular to an anti-loosening bolt bit. Background Technology

[0002] Screwdriver bits, generally speaking, refer to the screwdriver heads that are mounted on electric drills or hammer drills to tighten or loosen screws. Electric screwdriver bits are used to tighten or loosen screws and are small power tools. Screwdriver bits can be classified according to different head shapes, such as slotted, Phillips, star, square, hexagonal, and Y-shaped heads. Among them, slotted and Phillips are the most commonly used in daily life, while hexagonal heads are not used as often. Hex wrenches are more commonly used. Many screws on some machines have internal hexagonal holes, which allows for force to be applied from multiple angles.

[0003] A bolt cutter bit mainly consists of a shank, a head, and a shaft. The main function of a bolt cutter bit is to facilitate the quick and easy removal and installation of screws. By using the appropriate bit, screws can be tightened or loosened quickly, greatly improving work efficiency. Furthermore, different head designs can accommodate various screw specifications, reducing the difficulty of operation.

[0004] In existing anti-loosening screwdriver bits, the shank and head are usually a single piece. If the head wears out, the entire bit needs to be replaced, which increases costs.

[0005] Therefore, it is necessary to provide a bolt cutter bit that prevents loosening to solve the above-mentioned technical problems. Utility Model Content
