Abstract

The invention discloses a novel bolt. The novel bolt comprises a head, a first threaded rod, a second threaded rod and a nut, wherein the first threaded rod is in a circular truncated cone shape, the radius of the upper bottom surface of the first threaded rod is greater than that of the lower bottom surface of the first threaded rod, at least one groove is formed in the side face of the first threaded rod, the upper bottom surface of the first threaded rod is fixedly connected with the head, the lower bottom surface of the first threaded rod is fixedly connected with the top of the second threaded rod which is cylindrical, the radius of the second threaded rod is identical to that of the lower bottom surface of the first threaded rod, and the second threaded rod is matched with the nut for use. Thus, the novel bolt is prevented from being unscrewed by a user without authorization, non-specialized persons are prevented from damaging objects, and the novel bolt is high in connection strength and good in use effect.
