[0002] Screws are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually fasten objects and parts. Screw is a general term for fasteners and a daily colloquialism. Screws are an indispensable industrial necessity in daily life: such as the very small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; large screws and nuts are used in engineering, construction, and bridges; transportation vehicles, airplanes, trams, cars, etc. use both large and small screws. Screws have important tasks in industry, and as long as there is industry on the earth, the function of screws will always be important.

[0003] Screws, some people call it "screws" (screws) and "screw rods" (screw rods). In fact, screws are a general term, while screws and screw rods are different from each other. Screws are generally called wood screws; they are the kind with a pointed front end and a larger pitch, and are generally used to fasten wooden and plastic parts. Screw rods are machine screws (mechanical screws), which are the kind with a flat front end and a smaller and uniform pitch, and are generally used to fasten metal and machine parts. Most of the current screw forming punches generally use a two-section plug-in type, which is then locked and fixed by screws. However, this connection method is more troublesome when replacement or maintenance is needed, and it is inconvenient for staff to operate. Therefore, it may cause the staff's work progress to be slow during the processing process, affecting work quality and production efficiency. Utility Model Content
