Abstract

The invention discloses an anti-theft screw with a concave-convex surface on a screw hole top in a heat treatment stiffening screw top, which is an anti-theft screw for a non-standard fastener. The anti-theft screw comprises a heat treatment quenching stiffening screw body (1), a top surface (4) of a screw top and the like, wherein a bulged dextrorotation butting bar (34) which is screwed in the top surface of the screw top in the clockwise direction or a bulged levorotation butting bar (44) which is screwed in the top surface of the screw top in the anticlockwise direction are arranged on the top surface (4) of the screw top. After the anti-theft screw is matched with tools such as movable sleeves, ratchet handle wrenches and the like which have corresponding specifications and shapes, are used for assembling and disassembling two profiled threads and are provided with the concave-convex surface screws on the screw tops, a large number of wiring opening covers in the bottom sections of lamp poles arranged outdoors can be subjected to anti-theft arrangement or replacement, so the anti-theft screw has obvious social benefits.

Description

technical field [0001] The invention is a non-standard screw in a fastener. After the invention is used together with tools such as movable sleeves and wrenches with different threads for assembly and disassembly of corresponding specifications and shapes and screws with concave-convex surfaces on the top of the screw, wrenches, etc., the screw can be fixed. A large number of wiring port covers and cover holes at the bottom of street lamp posts installed outdoors have been used for anti-theft fixed installation or anti-theft installation for dismantling the old and replacing the old with a new one, and its social benefits are obvious. Background technique [0002] So far, there is still a lack of truly effective, easy to assemble and disassemble, anti-theft and reliable anti-theft screws and special tools for assembly and disassembly, resulting in a large number of easy-to-theft facilities installed outdoors being stolen and sold, which has caused serious damage to people's p...
