Abstract

The invention discloses a detachable screw. The detachable screw comprises a double-screw bolt and a screw cap which are of a split structure. A cross groove is formed in the screw cap. The double-screw bolt and the screw cap are in threaded connection. A threaded segment is arranged at the upper end of a threaded rod. A threaded hole is formed in corresponding portion in the middle of the screw cap. The threaded segment is screwed into the threaded hole so that threaded connection can be achieved. An anti-slip groove is formed in the peripheral face of the screw cap and surrounds the whole screw cap by a circle. When the detachable screw is used, the screw cap and the double-screw bolt are installed together, then the screw cap and the double-screw bolt are screwed into a screw installing hole, after installation is completed, the screw cap is screwed out of the double-screw bolt, and therefore the screw cap and the double-screw bolt can be separated, and the requirements of some special using occasions are met.

Description

technical field [0001] The invention relates to a screw, in particular to a detachable screw. Background technique [0002] Screws are fasteners used to fix objects, and are widely used. Usually, the screws are installed in the screw holes of the object to be fixed and the object connected with the fixed object, and then the fixing can be implemented. The screw and the screw hole are screwed together. But present screw is integral structure, can not be disassembled between screw rod and nut, can not satisfy some special occasions of use. Contents of the invention [0003] The object of the present invention is to provide a detachable screw in order to overcome the deficiencies of the prior art. [0004] The present invention is realized through the following technical solutions: [0005] A detachable screw, including a stud and a nut, the stud and the nut are split structures, a cross groove is opened on the nut, and the stud and the nut are connected by threads, A thr...
