In sum, it is an object of the invention to solve the technical deficiency that existing anti-theft screw has tamper effect difference,
And propose a kind of anti-theft screw of employing screw rod encryption.
To solve technical problem proposed by the invention, the technical scheme for adopting for：It is antitheft that a kind of employing screw rod is encrypted
Screw, includes screw rod and the nut located at screw rod tail end, it is characterised in that：There are a cavity, screw rod in the front end of described screw rod
Side wall be provided with the location hole communicated with cavity, flexible clamp piece is provided with the cavities；Described flexible clamp piece includes that elasticity is curved
Pars convoluta and the dop being extend out to by the located hole of elastic force effect of elastic bend part outside the wall of screw rod side.
Echnical solution as defined further in the present invention is included：
A location hole communicated with cavity, flexible clamp piece are respectively equipped with the relative both direction side wall of described screw rod
Two are included respectively positioned at the dop of elastic bend part both sides.
Described flexible clamp piece is the structure that elastic metal wire or elastic sheet metal are folded.
Described screw front end has been threaded connection a swivel nut, and the diameter of swivel nut is less than or equal to screw body diameter；
Screw rod side wall is located at and the longitudinally mounted groove loaded for flexible clamp piece is provided between location hole and screw front end.
Described nut and inside screw is provided with longitudinal direction and is used to logical solution lock access.
Dust plug is provided with described screw cavity.
Beneficial effects of the present invention are：The present invention is improved using the screw portion to screw, and bullet is increased in screw rod
Property fastener, when screw is screwed into, is first pressed into the dop of flexible clamp piece in location hole, when screw locking in place after, elastic card
Part is flicked in the opposite side of nut, prevents screw unscrewed from exiting, and reaches real tamper effect.

Specific embodiment
The structure of the present invention is further described below in conjunction with accompanying drawing and currently preferred specific embodiment.
Embodiment 1
Screw rod 1 and the nut located at the tail end of screw rod 1 are included referring to figs. 1 to the anti-theft screw of the present embodiment shown in Fig. 4
2, there is a cavity 11 in the front end of screw rod 1, the side wall of screw rod 1 is provided with the location hole 12 communicated with cavity 11, in cavity 11
It is provided with flexible clamp piece 3.
Wherein, preferred scheme is to be respectively equipped with one on the relative both direction side wall of screw rod 1 to communicate with cavity
Location hole 12, flexible clamp piece 3 includes elastic bend part 31 and two dops 32 for being located at the both sides of elastic bend part 31 respectively, often
Two dops 32 are acted on located hole 12 and are extend out to outside the side wall of screw rod 1 by the elastic force of elastic bend part 31 under state.Flexible clamp piece 3
For the structure that elastic metal wire is folded, elastic bend part 31 is V-structure, during assembling, is clamped by Special clamping instrument
Elastic bend part 31, and its deformation is made, send into afterwards in cavity 11, elastic bend part 31 is discharged, make two dop 32 distinguish Jing two
The bullet of location hole 12 stretches out the side wall of screw rod 1.
When fastening object is needed, after screw rod 1 is screwed into 12 nut location of location hole, by instrument by flexible clamp piece
Dop 32 is pressed in location hole 12, and is continued to turn screw rod 1 and advanced, and makes the elastic top of dop 32 in the inwall of nut；When this
Bright screw locking in place after, flexible clamp piece 3 is flicked in the opposite side of nut, and dop 32 is ejected in the location hole 12, so as to prevent
Screw unscrewed of the present invention is exited, and reaches real tamper effect.
Nut 2 can adopt the nut structure of existing any one type, for example：Turret head, interior hexagonal, interior six flower, a word
Groove, countersunk head, flat round head or spline are first-class etc..Existing this theft-prevention structure on market is also adopted by nut 2, such screw is just opened
To double insurance effect.
Embodiment 2
With reference to shown in Fig. 5, the present embodiment is the further improvement to embodiment 1, and embodiment 1 is to dismantle, and is one
Secondary property structure, can only be using destructive dismounting；In order to realize repeating to reuse, can be removed by hexagon wrench special,
Longitudinal direction is provided with inside nut 2 and screw rod 1 and is used to logical solution lock access 5；Increase a rod iron, rod iron in the end of traditional die nut
When unlocked passage 5 first jacks down flexible clamp piece 3, dop is also just stretched back, and screw of the present invention just can be unloaded with unscrewed.In tool
In body embodiment, it is also possible to which solution lock access 5 is designed to into blind hole, when needing to remove, then got through by electric drill.
Embodiment 3
With reference to shown in Fig. 6 to Fig. 9, the present embodiment principle is same as Example 1, and except for the difference that flexible clamp piece 3 is elasticity
The structure that sheet metal is folded.Assemble for the ease of flexible clamp piece 3, the front end of screw rod 1 has been threaded connection a swivel nut 6, spiral shell
The diameter of set 6 is less than or equal to screw body diameter, that is to say that swivel nut 6 can not hinder to be threadedly coupled between screw rod 1 and nut；Spiral shell
The side wall of bar 1 is located at and the longitudinally mounted groove 13 loaded for flexible clamp piece is provided between location hole 12 and screw front end.
It is dust-proof to cavity 11 in order to realize, it is provided with dust plug in the cavity 11 of screw rod 1.
Embodiment 4
With reference to shown in Figure 10, the present embodiment is that embodiment 3 is further improved, for realize it is reusable increase and
The solution lock access 5 of the identical structural principle of embodiment 2.
