Problems solved by technology
[0002] In mechanical equipment, most of the connections between parts are realized by threads and nuts. However, due to the vibration of the machine during operation, after a period of use, the bolts and nuts will not There is often a slack phenomenon between them. Once this happens, it may cause the equipment to fail to work normally, and even cause other major safety accidents.
