Referring to Fig. 1, existing be illustrated anti-theft bolt provided by the invention.Anti-theft bolt, including screw rod 1 and and screw rod
What 1 end was connected is not easy to the antitheft portion 21 of clamping, and antitheft portion 21 is equipped with far from the side of screw rod 1 for rotary screw 1
Force section 22, be equipped between antitheft portion 21 and force section 22 can under external force impact the interconnecting piece 23 that disconnect, interconnecting piece 23 it is outer
Diameter is less than the outer diameter in antitheft portion 21 and the outer diameter of force section 22.
Compared with prior art, anti-theft bolt provided by the invention is connect by screw rod 1 with by fastener, and fastening tool is logical
It crosses and acts on 22 rotary screw 1 of force section and be fastenedly connected with by fastener, external force strikes interconnecting piece 23 after the completion of fastening, makes to apply
Power portion falls off, and due to the acting surface that antitheft portion 21 is clamped without tool, achievees the purpose that antitheft.
The intensity of interconnecting piece 23 should meet fastening tool rotation and tighten screw rod 1 and connection by fastener, but be readily susceptible to by
It strikes or twists off.
Further, Fig. 1 and Fig. 2 are please referred to, as a kind of specific embodiment of anti-theft bolt provided by the invention, is prevented
Outside of the robber portion 21 far from screw rod 1 is smooth spherical cambered surface, and force section 22 is arranged on spherical cambered surface.It antitheft portion 21 can be convex for taper
Platform or spherical arc shape boss, the present embodiment are not limited.
Further, referring to Fig. 2, a kind of specific embodiment as anti-theft bolt provided by the invention, antitheft portion
21 are equipped with blind hole 31, and the axis of blind hole 31 is overlapped with the axis of screw rod 1, and blind hole 31 is perpendicular to the flat of 1 axis direction of screw rod
It is projected as nonstandard hole on face, interconnecting piece 23 at least two, each interconnecting piece 23 is fixed on antitheft around the axisymmetrical of screw rod 1
In portion 21.Screw rod 1 and after being reliably connected by fastener, interconnecting piece 23 falls off, and antitheft portion 21 is pressed on as bolt head and is fastened
On part, if necessary to overhaul to by fastener, then just needing to unscrew bolt, the blind hole 31 in the present embodiment, which can be used as, to be applied
Power hole and extracting tool are clamped, and since blind hole 31 is nonstandard hole, can not be clamped blind hole 31 using common die nut and be unscrewed
Screw rod 1 achievees the purpose that antitheft；Since blind hole 31 being arranged in antitheft portion 21, interconnecting piece 23 needs to be fixed on the outside of blind hole 31,
When reversing force section 22 to facilitate fastening tool, screw rod 1 can smoothly be fallen into the screw hole by fastener, and multiple interconnecting pieces 23 need
