Card slot there are five being set on side wall.
Preferably, five card slots are distributed on the outer wall of nut.
Preferably, the outer wall of the nut is circular cone shape, the top edge arc transition of the nut.
Preferably, the adjacent wall of two neighboring card slot is parallel to each other.
Preferably, the nut, gasket and screw rod are an integral structure.
Preferably, the angle of the card slot is 102 °.
The utility model also provides a kind of and above-mentioned outer five jiaos of matching used spanners of anti-theft screw, and the spanner includes pulling
Handle and driving end, the driving end are hollow tube, and the inner wall of the driving end is equipped with upper five fins, the fin and spiral shell
Card slot cooperation on cap.
Preferably, be equipped with connection handle between the spanner handle and driving end, the outer diameter of the connection handle be less than driving end and
The external dimensions of spanner handle.
Preferably, the cross section of the spanner handle is hexagon.
The beneficial effects of adopting the technical scheme are that compared with prior art, the utility model has knot
The advantages of structure is simple, good anti-theft effect, dismantles anti-theft bolt using matched spanner, the fin and spiral shell of driving end inner wall
The card slot of cap outer wall cooperates, and while increasing torque, can also play the role of anti-skidding, be played using this special construction antitheft
Effect can effectively prevent theft accident to occur, avoid property loss.The utility model facilitates installing and dismounting, stability and
It is good with property, facilitate popularization and application.

Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu is fully described by, it is clear that and described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The outer five jiaos of anti-theft screws of one kind as shown in Figure 1, 2, it is described including screw rod 1 and the nut being set at the top of screw rod 1
The surface of screw rod 1 is equipped with external screw thread, and the top surface of the nut 2 is equipped with groove 3, and the bottom of the nut 2 is fixed with protrusion
Annular gasket 4；Card slot 5 there are five being set on the side wall of the nut 2.It wherein, can be according to actual requirement, reasonable set nut bottom
Gasket outer diameter.
In a specific embodiment of the utility model, five card slots 5 are distributed on the outer wall of nut 2.Facilitate processing
While production, also facilitates and load and unload outer five jiaos of anti-theft screws with spanner cooperation.Wherein, the adjacent wall phase of two neighboring card slot 5
It is mutually parallel.
As a kind of preferred structure, the outer wall of the nut 2 is circular cone shape, the top edge circular arc mistake of the nut 2
It crosses, prevents plowing from staff.
In order to increase integral strength, the nut 2, gasket 4 and screw rod 1 are an integral structure, machining by bar.
In a specific embodiment of the utility model, the angle of the card slot 5 is 102 °.
