Furthermore, the cross section center of the special-shaped groove is circular, four squares are uniformly distributed on the circle, and the circle and the squares form a closed loop.
Furthermore, the elastic gaskets are symmetrically arranged relative to the rod part.
Furthermore, the elastic gaskets are staggered relative to the rod part.
Furthermore, a degradable plastic bag is clamped between the elastic gasket and the rod part, and glue is filled in the degradable plastic bag.
The utility model has the beneficial effects that:
1. the special-shaped groove is formed in the head of the special-shaped screw, the screw can be installed only by a special matched tool, and the special-shaped groove is sealed by the groove cover after being installed, so that lawbreakers cannot take out the special-shaped groove by a conventional means.
2. The elastic gasket and the rod part are integrally provided with the coherent threads, so that screwing in use is not hindered, the elastic gasket can be abutted against objects to be fastened in the process of recovering the shape, and the stability is improved
3. The degradable plastic bag is clamped between the elastic gasket and the rod part and filled with glue, and the degradable plastic bag is pressed in the installation process to cause the glue to flow out and then to solidify, so that the anti-theft property and the stability of the anti-theft plastic bag are also improved.
