The utility model solves the technological scheme that its technical problem adopts: a kind of anti-theft screw, comprise the screw rod and nut that are connected as a single entity, described screw rod is provided with screw thread, the top of described nut offers for coordinating screw-driver thus ordering about the groove that described anti-theft screw rotates, the radial cross section of described groove is regular polygon, and locating column has stood still for a long while in the bottom centre of described groove.
As preferably, the radial cross section of described groove is equilateral triangle, and three limits of described equilateral triangle are waveform curve.
As preferably, described locating column be cylindrical and with described screw coaxial.
As preferably, the limit of described equilateral triangle comprises the first circular arc and symmetrical two the second circular arcs being connected to described first circular arc two ends, the center of circle of described first circular arc is dropped on the axis of described locating column, and described second circular arc protrudes towards the inside of described equilateral triangle.
As preferably, any two limits of described equilateral triangle are connected by curve.
As preferably, the size of the central angle that described first circular arc is corresponding is 30 ~ 120 °.
As preferably, the radial cross section of described groove is regular pentagon.
As preferably, described locating column is straight cylinder, and the longitudinal center line of described locating column and the central shaft of described screw rod are point-blank.
The beneficial effects of the utility model are, this anti-theft screw is the groove of regular polygon and the cooperation of locating column by radial cross section, form a kind of special structural form, must given shape the screw-driver that agrees with mutually with it could drive screw to rotate, there is very strong Anti-dismantling and theftproof performance.
