Problems solved by technology

If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. However, in the actual use of the existing bolts, due to the vibration between the connecting parts, the bolts have been in service for a long time. After that, it is easy to loosen, which will affect the stability between the connecting parts, and even cause the connecting parts to loosen and fall off, resulting in casualties. Therefore, it is necessary to propose an anti-loosening bolt assembly
