Abstract

The utility model relates to an antitheft nut removal tool, which comprises a holding part, a clamping part and a power assisting rod. The holding part consists of a plurality of clamping jaws; grooves are arranged on the outer sides of the tails of the clamping jaws; the clamping jaws are bound together by a coil spring along the grooves; structures clamping two sides and the bottom surface of a protective sleeve of an antitheft nut are arranged inside the clamping jaws; the outside of the holding part is in a frustum shape or a structure with a part of a frustum after the protective sleeve is clamped; a hole for the power assisting rod to penetrate through is arranged at the tail of the holding part; the hole is provided with a grip projection for gripping the power assisting rod; the clamping part is provided with a hollow conical structure clamping the outside of the holding part; a hole for inserting the power assisting rod is arranged on the back of the clamping part; a prism structure is arranged outside the clamping part; a screw is arranged at the tail of the power assisting rod; the clamping part is arranged outside the holding part; the power assisting rod penetrates through the holes at the tails of the holding part and the clamping part; and a screw is arranged on the back of the power assisting rod. The antitheft nut disassembling tool has the advantage of capability of disassembling the antitheft nut.

Description

A kind of anti-theft nut extracting tool

Technical field

The utility model relates to the instrument class, relates to a kind of anti-theft nut extracting tool.

Background technology

The utility model relate to the structure of anti-theft nut be such: it comprises nut body and protective jacket, the surface that described nut body outside has truncated cone-shaped; Described protective jacket inside has the hollow-core construction of identical nut body truncated cone-shaped, and the outside has prism structure; Nut body and protective jacket are bonding before using; the round platform handle of nut body is introduced into bolt during use; unclamp acquire a certain degree back nut body and protective jacket abutting edge; because nut body is the truncated cone-shaped structure; protective jacket can not be removed yet, and it is trapped in the nut body outside and reaches the protection nut body, prevents stolen effect.In the prior art, want to lay down such nut and also do not have special instrument.

Summary of the invention

The purpose of this utility model is exactly at above-mentioned shortcoming, and a kind of simple in structure, the instrument that can dismantle this anti-theft nut is provided.

The purpose of this utility model is achieved in that the anti-theft nut extracting tool, it is characterized in that: it comprises holds part tightly, has jurisdiction over tight part, boosting-rod, the described part of holding tightly is that the multi-disc claw is formed, the afterbody outside of claw has groove, also have coil spring it to be bundled along groove, inside has the protective jacket both sides of having jurisdiction over anti-theft nut and the structure of bottom surface, hold the outside structure that becomes the part of truncated cone-shaped or round platform of part later on tightly having jurisdiction over protective jacket, afterbody has the hole of wearing boosting-rod, also has the projection of controlling of controlling boosting-rod on this hole; The tight part of described linchpin has is having jurisdiction over the conical hollow structure of holding the part outside tightly, and the rear portion has the hole of interspersed boosting-rod, and the outside has prism structure; Described boosting-rod afterbody has screw; Annexation is: have jurisdiction over tight part in the outside of holding part tightly, boosting-rod passes the hole of holding part and the tight part afterbody of linchpin tightly, and there is screw at the boosting-rod rear portion.

The beneficial effects of the utility model are: the anti-theft nut extracting tool of this spline structure has the advantage that can dismantle this anti-theft nut.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of the tight part of linchpin.

Fig. 3 is the structural representation of boosting-rod.

Wherein: 1, hold tightly part 2, the linchpin tight part 3, boosting-rod 4, claw 5, spring 6, bottom surface 7, control the projection 8, screw

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, the anti-theft nut extracting tool, it is characterized in that: it comprises holds part 1, the tight part 2 of linchpin, boosting-rod 3 tightly, the described part 1 of holding tightly is that multi-disc claw 4 is formed, the afterbody outside of claw 4 has groove, also have coil spring 5 it to be bundled along groove, inside has the protective jacket both sides of having jurisdiction over anti-theft nut and the structure of bottom surface 6, hold the outside structure that becomes the part of truncated cone-shaped or round platform of part 1 later on tightly having jurisdiction over protective jacket, afterbody has the hole of wearing boosting-rod 3, on this hole, also have control boosting-rod control the projection 7, as shown in Figure 2; The tight part 2 of described linchpin has is having jurisdiction over the conical hollow structure of holding part 1 outside tightly, and the rear portion has the hole of interspersed boosting-rod, and the outside has prism structure, as shown in Figure 3; Described boosting-rod 3 afterbodys have screw 8; Annexation is: have jurisdiction over tight part 2 in the outside of holding part 1 tightly, boosting-rod 3 passes the hole of holding part 1 and tight part 2 afterbodys of linchpin tightly, and there is screw 8 at boosting-rod 3 rear portions.

During use, hold part 1 tightly and have the sidepiece and the bottom of the protective coat of anti-theft nut in arms, has pyramidal structure owing to hold the outside of part tightly, having jurisdiction over tight part 2 can make under the effect of boosting-rod 3 afterbody screws 8 and hold part 1 tightly to clip protective coat tighter, protective coat, anti-theft nut body, this instrument are become one, have jurisdiction over tight part 2 outsides and have prism structure, can use spanner that anti-theft nut is laid down.
