Abstract

The invention discloses a movable sleeve for mounting and dismounting a screw with two different threads and a top resisting part on a screw top, which relates to a mounting and dismounting special tool for a non-standard fastening piece burglarproof screw. The movable sleeve comprises a movable sleeve outer bottom section hollow barrel (11), an outer bottom section hollow barrel bottom surface (13) and the like, wherein an outer bottom section barrel bottom surface clockwise screw-in convex-high-type right-handed rotation top resisting part (130) or an outer bottom section barrel bottom surface anticlockwise screw-in convex-high-type left-handed rotation top resisting part (230) is arranged on the outer bottom section hollow barrel bottom surface (13). After the sleeve is matched with the burglarproof screw and the like which has a corresponding specification and a corresponding shape and of which the screw hole top in the screw top is provided with the top resisting parts, a large number of streetlamp pole column bottom section wiring opening cover fixing holes which are formed outdoors are fixedly formed in a burglarproof mode or formed in a trade-in burglarproof mode, so that the movable sleeve has an obvious social benefit.

Description

Technical field [0001] The invention is a special assembling and disassembling tool for assembling and disassembling non-standard fasteners and anti-theft screws. After the invention is used in conjunction with two different threads and nail tops of corresponding specifications and shapes, the anti-theft screws, ratchet handle wrenches, etc. It can be used for anti-theft fixed installation or depreciation-for-new anti-theft installation on a large number of outdoor lamp pole bottom section wiring port cover holes, and its social benefits are obvious. Background technique [0002] So far, there is still a lack of truly effective, easy to install and disassemble, and reliable anti-theft screws and their special tools for installation and disassembly. As a result, a large number of outdoor facilities are constantly being stolen and sold. It has caused varying degrees of damage to people’s production and life. Constraints and influences. Summary of the invention [0003] The purpose ...
