[0013] Beneficial effects

[0014] Compared with existing technologies, this new multi-functional combination fastener, through its internal moving groove and fixed seat structure, allows the top cover to be opened. Under the action of a spring, the force rod can pop out the nut, and the force rod extends out, pushing the force rod to drive the nut to rotate. This ensures stable operation and improves the efficiency of nut disassembly and installation. When locking the nut, rotating the threaded rod causes the wear-resistant block above to tightly engage with the bolt teeth. The locking teeth on the wear-resistant block will lock the bolt teeth, increasing friction and achieving a tight lock. This strengthens the locking effect of the fastener and prevents loosening. The lubrication groove allows for the addition of lubricating oil when needed, ensuring smooth disassembly even if the nut is rusty. Attached Figure Description
