AI Technical Summary
Existing chucks are usually made of plastic, which is not very durable and is easily damaged by wear and tear after prolonged use.
The design employs a movable chuck and a fixed chuck, both of which include a fixed connection mechanism. The outer wall of the fixed chuck's tube has a threaded layer, while the movable chuck's tube is connected to an outer sleeve ring. A steel pipe is used for connection, and the steel pipe and other parts made of hard plastic form the chuck structure, improving wear resistance.
The design enhances the durability of the chuck, and the wear resistance of the steel pipe improves the overall durability of the chuck, making it more than five times more durable than existing devices and highly practical.
