Abstract

The utility model relates to a general type of four beaks pulls hook special vice, including handle, articulated shaft and pincers mouth, the pincers mouth comprises the binding clip that two longitudinal symmetries set up, the binding clip comprises the pincers beak that two bilateral symmetry set up, be provided with the groove between two pincers beaks, pincers beak top is the closed angle form. The groove width is greater than the draft arm that pulls hook upper portion to make this draft arm can pass the groove. This device simple structure, the centre gripping is quick, fastens effectually.

Description

The universal hook special vice of a kind of four beak

Technical field

This utility model relates to the universal hook special vice of a kind of four beak.

Background technology

Hook special vice is a kind of a kind of apparatus be clamped to by free hook on orthodontic arch wire.Arch wire, through free hook, clamps the distortion of its clamping part by special vice thus card holding-solid fixes on arch wire, and the hook be fixed on arch wire drives arch wire to slide by pull strength.

Existing hook special vice only devises a pincers beak, and be positioned on a binding clip, another binding clip is two grip blocks, and the groove between two grip blocks is for through the draft arm on hook.The hook special vice of this kind of design clamps beak owing to only having one, one is that special vice will turn and draft arm could be sticked into groove to direction, two is when exerting a force clamping hook, place's deformation point can only be produced at the clamping part of hook, the frictional force that clamping part distortion produces causes hook to loosen slippage lower than pull strength sometimes, and then impact treatment, three is that 3 force patterns that pincers beak and two grip blocks are formed easily cause arch wire to be out of shape.

Utility model content

This utility model makes improvement for above-mentioned prior art Problems existing, and namely technical problem to be solved in the utility model is to provide the universal hook special vice of a kind of four beak, and convenient clamping, fastening effect is good.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: the universal hook special vice of a kind of four beak, comprise handle, jointed shaft and jaw, described jaw is made up of about two symmetrically arranged binding clips, described binding clip is made up of the pincers beak that two are symmetrical set, be provided with groove between described two pincers beaks, described pincers beak top is tip-angled shape.

Further, described slot width is greater than the draft arm on hook top, can pass groove to make this draft arm.

Compared with prior art, this utility model has following beneficial effect: this professional tonger has the Characteristic Design of two four beak, and four pincers beak clamping hooks can produce deformation point everywhere at clamping part, and its frictional force produced is much larger than original product.Meanwhile, the groove on two binding clips is also conveniently looked for and is entered groove to the draft arm on hook.The clamping plane of four pincers beaks formation is not easy to cause arch wire to be out of shape.

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

Accompanying drawing explanation

Fig. 1 is the organigram of this utility model embodiment.

Fig. 2 is the organigram of the using state of this utility model embodiment binding clip.

In figure: 1-handle, 2-jointed shaft, 3-jaw, 31-binding clip, 32-clamps beak, 33-groove, 4-hook, 41-draft arm, 5-arch wire.

Detailed description of the invention

Embodiment one: as shown in Figure 1 and 2, the universal hook special vice of a kind of four beak, comprise handle 1, jointed shaft 2 and jaw 3, described jaw 3 is made up of about two symmetrically arranged binding clips 31, described binding clip 31 is made up of the pincers beak 32 that two are symmetrical set, be provided with groove 33 between described two pincers beaks 32, described pincers beak 32 top is tip-angled shape.

In the present embodiment, described groove 33 width is greater than the draft arm 41 on hook 4 top, can pass groove to make this draft arm.

By hook 4 through after arch wire 5, block hook with the binding clip of this special vice, in the groove that the draft arm on hook is fallen on binding clip, firmly clamping, hook can be produced four point deformation by clamping part.

The foregoing is only preferred embodiment of the present utility model, all equalizations done according to this utility model claim change and modify, and all should belong to covering scope of the present utility model.

Claims

1. the universal hook special vice of beak, comprise handle, jointed shaft and jaw, it is characterized in that: described jaw is made up of about two symmetrically arranged binding clips, described binding clip is made up of the pincers beak that two are symmetrical set, be provided with groove between described two pincers beaks, described pincers beak top is tip-angled shape.

2. the universal hook special vice of four beak according to claim 1, is characterized in that: described slot width is greater than the draft arm on hook top, can pass groove to make this draft arm.
