Abstract

The invention discloses a fastening type screw spike. The fastening type screw spike is characterized by comprising a nut, a screw and a bolt; one end of the screw is fixedly connected with the nut, and the other end of the screw is fixedly connected with the bolt; and a groove is formed in the top end of the nut, and the structure of the groove is in a cross shape. The fastening type screw spike has the advantages that spiral teeth are arranged on the two sides of the screw, the screw spike can be effectively prevented from loosening and the fastening effect can be further achieved.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to a fastening screw. Background technique [0002] A screw, a class of sharp-ended, nail-like, threaded parts on small cylindrical or conical metal rods, having a grooved or dimpled head, used alone. [0003] An existing fastening screw has a nail cap, a nail body, and a nail tip, and arc-shaped threads are arranged around the nail body. When using fastening screws of this structure, it is laborious to drive in, the cap is easily deformed, and the fastening effect is not good. Contents of the invention [0004] The object of the present invention is to address the deficiencies of the prior art, and now provide a fastening screw that has a good fastening effect and can only be tightened but not loosened. [0005] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a fastening screw, the innovation point of which is...
