An encrypted composite screw and a supporting screwdriver assembly

Abstract

The invention provides an anti-tamper composite screw and a screwdriver assembly used in cooperation with the anti-tamper composite screw. The composite screw is mainly composed of a big screw body, a small screw body and protrusions, wherein the small screw body is arranged in the big screw body and is in screw-thread fit with the big screw body, and the protrusions play an anti-tamper role. The screwdriver assembly is composed of a screwdriver body, a screw-in head and a screw-out head, wherein the screwdriver body comprises an upper handle, a middle barrier transition part and a lower mounting part. The screw-in head or the screw-out head of the screwdriver assembly is used for screwing the small screw body of the composite screw in or out of a component to be connected with; through cooperation of the protrusions and the barrier transition part, the big screw body or the small screw body can be screwed in or screwed out. Since the anti-tamper composite screw and the screwdriver assembly are used in cooperation with each other, a product can be prevented from being demounted at will; moreover, anti-tamper parts of the anti-tamper composite screw and the screwdriver assembly which are used in cooperation with each other can be changed when produced, so the situation that multiple composite screws can be screwed out by one screwdriver assembly simultaneously during mass production of the composite screws is avoided.

Description

technical field [0001] The invention relates to the technical field of fastening devices, in particular, the invention particularly relates to an encrypted composite screw and a matching screwdriver assembly. Background technique [0002] With the development of society, the generalization of electronic products has basically been realized. The installation of electronic products is generally fastened with standard screws. The generalization of electronic products has also brought more maintenance of electronic products. Now electronic products are specialized There are diversifications in maintenance. For general failures of electronic products, due to time and place issues, electronic product owners tend to repair in non-warranty repair shops, which can save time and repair on the spot, but due to non-warranty The diversity of repair shops exists, and not every repairer can abide by the professional norms, and there will be random disassembly and replacement of parts witho...
