The shape in the figure is circular. Inserting a tool with a corresponding opening shape into the second socket 806, the first socket 10 and the plug sleeve 807 can lock the outer sleeve 804 and the inner sleeve 801. At this time, the outer sleeve 804 rotates and the inner sleeve 801 also rotates, so that the outer sleeve 804 and the inner sleeve 801 will rotate at the same time when the screw handle 7 is turned. If the outer sleeve 80 4 and the inner sleeve 801 are locked. When the screw handle 7 is turned, the outer sleeve 804 cannot drive the inner sleeve 801 to rotate. The inner sleeve 801 is threadedly connected to the screw rod 1. The screw barrel 3 cannot be removed without the inner sleeve 801 rotating. Then the screw handle 7 cannot be turned. If a specific tool is used to lock the outer sleeve 804 and the inner sleeve 801 at this time, the outer sleeve 804 can drive the inner sleeve 801 to rotate. When the screw handle 7 is turned, the protective shell 5 will rotate, thereby driving the outer sleeve 804 and the inner sleeve 801 to rotate, and the screw barrel 3 can be removed from the screw rod 1, thereby achieving an anti-theft effect. If the locking nut 9 is exposed to the outside, even if the thief unscrews the locking nut 9, the screw barrel 3 cannot be removed from the screw rod 1, so that the thief cannot remove the screw rod 1.

[0027] Through the above steps, by setting the anti-theft component 8, specific tools are needed to fix and remove the screw 1, and this method is less popular, in order to solve the problem that due to the popularity of standard nuts and the general availability of matching tools, the threshold for illegal disassembly is inadvertently lowered, providing opportunities for criminals.
