Abstract

The invention discloses an anti-theft screw with a top resistance and an outer peripheral wall on the inner concave hole wall of the nail top, which is a non-standard fastener screw. The present invention includes a screw body (1) and a concave hole wall (9) in the top of the screw, etc., and the concave hole wall (9) in the top of the screw is provided with a right-handed concave hole wall in the top of the screw which is screwed clockwise. Type top resists file (19) or screw top inner hole wall anticlockwise and screwes into left-handed concave type top to resist file (29). After the present invention is matched with the installation and disassembly tools such as the special wrench and other assembly and disassembly tools provided with the concave hole wall on the top of the assembly and disassembly nail with corresponding specifications and shapes, it can be used to cover a large number of wiring ports at the bottom of the street lamp pole column installed outdoors. The concave shape fixing hole is used for anti-theft fixed installation or the anti-theft installation for replacing the old with the new, and its social benefit is obvious.

Description

technical field [0001] The present invention is a non-standard screw in fasteners. After the present invention is used in conjunction with tools such as a special wrench that resists the anti-theft screw on the inner concave hole wall of the top of the assembly and disassembly nail of corresponding specifications and shapes, it can be used for a large number of screws. The anti-theft fixed installation or the anti-theft installation of removing the old and replacing the old with the new is used in the concave-shaped fixing hole of the wiring opening cover of the bottom section of the street lamp pole installed outdoors, and its social benefits are obvious. Background technique [0002] So far, there is still a lack of anti-theft screw products that are truly effective, easy to assemble and disassemble, and reliable in preventing theft, resulting in a large number of outdoor easy-to-theft facilities being stolen and sold. It has restricted and affected people's production and ...
