Abstract

The invention discloses a special-shaped screw. The special-shaped screw comprises a first main body and a second main body, wherein the first main body comprises an upper screw head, an upper screw, an upper cross-shaped slot and a jack; the second main body comprises a lower screw head, a lower screw, a lower cross-shaped slot and a jack; the cross-shaped slots are located at the center position of the upper surfaces of the corresponding screw heads; the screws are connected with the lower surfaces of the corresponding screw heads; the jacks are formed in the side walls of the corresponding screws; and a screw hole symmetrical with the diameter of the lower screw is formed in the center of the upper screw. The special-shaped screw is simple in structure, reasonable in design and easy to mount and dismount, and the first main body and the second main body can be used in a combined manner and also can be used alone, so that a worker can conveniently use the special-shaped screw.

Description

technical field [0001] The invention relates to the field of fasteners, in particular to a special-shaped screw. Background technique [0002] The screw refers to a cylinder with a helical groove cut on the outer surface or a cone with a helical groove on the conical surface. Most of the existing screw rods are solid cylinders, which only play a fastening role. The solid material is relatively wasteful, and the fastening effect is not very good, and the function is relatively single. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a special-shaped screw with reasonable design and simple structure, which solves the problems of inconvenient disassembly, single function and easy falling off of the screw in the prior art. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a special-shaped screw, which includes: a first body and a second body;...
