As preferably, described projection includes vertical plane and cambered surface, is provided with preset pitch between the vertical plane of two described projections, and the cambered surface of each described projection is disposed adjacent with vertical plane.
As preferably, described preset pitch is 2-4mm.
As preferably, described in unscrew the 1/4-1/2 that aperture is screw diameter in hole.
As preferably, described screw rod is not connected with one end of nut and is provided with screw thread, and described reach is the 1/2 of screw rod.
As preferably, described metal material is the one in ferrum, aluminum, copper.
This utility model also provides for the Speical screwdriver of a kind of above-mentioned anti-theft screw, and including handle, described handle one end is installed with swing arm, described swing arm away from one end of handle be provided with described anti-theft screw unscrew the plug that hole is correspondingly arranged.
As preferably, described plug is cylindrical-shaped structure.
The beneficial effects of the utility model: be circumferentially with white space along nut by arranging on nut between two projections, and two projections, it is possible to make normal screws cutter can only be tightened by anti-theft screw and can not unscrew, serve antitheft function.
When staff needs repairing replacing parts, then by electric drill, the metal material unscrewed in hole is got through, inserted by supporting Speical screwdriver subsequently and unscrew hole, screw to the direction unscrewed and this anti-theft screw can be unscrewed, in order to the repair demolition of staff.

Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As shown in Figure 1, 2, this utility model provides a kind of anti-theft screw, including nut 1 and the screw rod 2 that is fixed in nut 1 lower end, wherein:
Nut 1 includes protruding 11 and unscrews hole 12, and protruding 11 are set to two and are arranged on the end face of nut 1, and these two projections 11 are in angular distribution, and are provided with white space between two projections 11 of circumference of nut 1.This concrete projection 11 includes vertical plane 111 and the cambered surface 112 being disposed adjacent with vertical plane 111, is provided with preset pitch between the vertical plane 111 of two projections 11, and this preset pitch is set to 2-4mm.Above-mentioned white space is disposed therein between the cambered surface 112 of a projection 11 and the vertical plane 111 of another projection 11.By the vertical plane 111 of two projections 11, use common screwdriver can realize tightening of the anti-theft screw to the present embodiment, and owing to protruding 11 are provided with cambered surface 112, and it is provided with white space between the cambered surface 112 of one of them projection 11 and the vertical plane 111 of another projection 11, common screwdriver cannot realize unscrewing anti-theft screw, if robber wants to commit theft, can only realize stealing purpose by the way of electric drill, cutting, but this mode can send the biggest noise, staff can guard against in time.By the anti-theft screw of the present embodiment, it is possible to the expensive equipment and instrument using this anti-theft screw is played anti-theft function.
Unscrew hole 12 and be provided with two, it is separately positioned on each protruding 11, and unscrew hole 12 to offer direction consistent with the length direction of screw rod 2, when unscrewing hole 12 and not using, metal material (not shown) it is filled with inside hole 12 unscrewing, concrete, this metal material can be for the one in ferrum, aluminum, copper.By filler metal material in unscrewing hole 12, when normal mounting tightens the anti-theft screw of the present embodiment, unscrew hole 12 cannot use, robber cannot unscrew anti-theft screw (except modes such as borings) by unscrewing hole 12, when staff carries out repair demolition, then by electric drill, the metal material unscrewed in hole 12 can be got through, by Speical screwdriver, anti-theft screw be unscrewed subsequently, to realize the dismounting of anti-theft screw.
The above-mentioned 1/4-1/2 that aperture is screw rod 2 diameter unscrewing hole 12, preferably the 1/2 of screw rod 2 diameter, when Speical screwdriver screws, it is possible to preferably realizes the support to Speical screwdriver and borrows power.
As preferred technical scheme, screw rod 2 is not connected with one end of nut 1 and is provided with screw thread (not shown), and the 1/2 of a length of screw rod 2 of screw thread.
This utility model also provides for a kind of Speical screwdriver screwing above-mentioned anti-theft screw and unscrewing, as shown in Figure 3, this Speical screwdriver includes handle 10, it is installed with swing arm 20 in one end of handle 10, swing arm 20 away from one end of handle 10 be provided with anti-theft screw unscrew the plug 30 that hole 12 is correspondingly arranged, this plug 30 preferably cylindrical-shaped structure, and then when carrying out when unscrewing of anti-theft screw, only the plug 30 of this specialty screwdriver need to be inserted got through unscrew in hole 12, screw with the backward direction unscrewed and can realize unscrewing of anti-theft screw, so that the repair demolition of staff.
