Abstract
The utility model discloses a special inner sleeve externally fitting type wrench socket for thermal treatment quenching hardened anti-theft screws capable of advancing and retreating,, which is an assembly and disassembly special tool for non-standard fastener anti-theft screws. The wrench socket comprises a special inner sleeve externally fitting type wrench socket body (1) for anti-theft screws capable of advancing and retreating, a round-through-hole vertical wall (5) inside the socket body or a round-through-hole slightly conical wall(6) inside the socket body and the like. The round-through-hole vertical wall (5) inside the socket body or part thereof is provided with at least one baffling conjoined structured vertically screw-in barrier (15) recessed clockwise along the round-through-hole vertical wall inside the socket body or at least one baffling conjoined structured vertically screw-in barrier (25) recessed counterclockwise along the round-through-hole vertical wall inside the socket body. After being assembled with corresponding tools, such as movable wrenches and the like, in use, the wrench socket can carry out assembly and disassembly of thermal treatment quenching hardened anti-theft screws which are provided with corresponding specifications and shapes and capable of advancing and retreating, while the anti-theft screw is an effective anti-theft protector for a large amount of easily stolen outdoor facilities, and thereby the wrench socket has evident social benefits.
