[0046] The working principle of the above embodiment is:

[0047] By holding the rotating block 581 to squeeze the rotating rod 582 and drive the clamping block 583 into the groove inside the nut 2, the rotating rod 582 can be rotated to drive the clamping block 583 to rotate on the rotating groove of the nut 2, thereby squeezing the connecting rod 653, so that the connecting rod 653 pushes the movable block 64 to drive the connecting block 631 to push the fixed block 633 into the fixed groove on the push rod 64, and the squeezed connecting spring 57 will reset and push the sliding block 55 to drive the push rod 54 to move upward, so that the positive pole magnet 634 is separated from the negative pole magnet 632, and the fixed rod 51 can be pushed out of the nut 2, and the maintenance The repairman or driver can rotate the top cover 4 to expose the disassembly groove 59 on the nut 2, and then use the disassembly tool to disassemble the nut 2 and the screw rod 1. After squeezing the fixing rod 51 to squeeze the top rod 54 to the bottom of the connecting groove, the negative magnet 632 on the connecting block 631 will attract the positive magnet 634 on the fixing block 633, so that the fixing block 633 will re-fix the top rod 54, so that it is difficult for the thief to rotate the top cover 4 to disassemble the nut 2 and the screw rod 1 through the disassembly groove 59 without rotating the assembly 58, thereby improving the anti-theft performance of the entire bolt.
