Abstract

The utility model relates to slip joint pliers and aims to provide the slip joint pliers which can reduce the workload of an operator on the basis of keeping original functions and have the characteristics of simple structure and easiness for operation. The utility model adopts the technical scheme that the slip joint pliers comprise two plier bodies which are symmetrically arranged and are mutually hinged; the two plier bodies are provided with two occlusive plier heads along one side of a hinged shaft; the two plier bodies extend along the other side of the hinged shaft to form two handles for holding; and the slip joint pliers are characterized by also comprising a torsional spring, wherein the torsional spring is sleeved on the hinged shaft and both ends of the torsional spring are respectively abutted against the two plier bodies so as to apply thrust for opening the plier bodies to the two plier bodies. The two plier bodies are respectively provided with opposite mounting grooves and both the ends of the torsional spring are respectively abutted against the insides of the two mounting grooves. In the two plier bodies, a regulating hole communicated with a hinged hole is formed on one plier body.

Description

A kind of slip-joint pliers

Technical field

The utility model relates to a kind of tonger, is specifically related to a kind of slip-joint pliers.

Background technology

In daily life and the repair work, often use slip-joint pliers clamping pancake or cylindrical metal part.Conventional slip-joint pliers comprise two calipers that are hinged, and a side of jointed shaft is a binding clip, is shaped on tooth portion on the binding clip, and caliper extends to form two handles along the opposite side of jointed shaft; During use, tight metal parts is stung by tooth portion, holds tight two handles, can tighten or unscrew metal parts.The defective of this type slip-joint pliers is: after the work that completes repairs, need two calipers be pulled open with hand and just can continue operation, use comparatively inconvenience, waste time and energy, operating efficiency is not high yet.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that the above-mentioned background technology exists, and a kind of improvement of slip-joint pliers is provided, and these slip-joint pliers also should be able to reduce operating personnel's workload, and have characteristics simple in structure, processing ease on the basis that keeps original function.

The utility model proposes following technical scheme:

A kind of slip-joint pliers comprise symmetric arrangement and two calipers that are hinged, and two calipers are along two binding clips of the side formation interlock of jointed shaft, and two calipers extend to form two handles that are used to grip along the opposite side of jointed shaft; It is characterized in that: said slip-joint pliers also comprise a torsion spring, and this torsion spring set is contained on the said jointed shaft, and the two ends of torsion spring are resisted against respectively on two calipers and make its open thrust so that two binding clips are applied.

Said two calipers are shaped on respectively in opposite directions and right mounting groove, and the two ends of said torsion spring are resisted against respectively in two mounting grooves.

In said two calipers, wherein be shaped on the adjustment hole that is communicated with hinge hole on the caliper.

The use principle of the utility model is:

The method for using of the utility model when the clamping parts is identical with conventional slip-joint pliers, and promptly tight parts are stung by the tooth portion of caliper, holds tight two handles, pulls handle then clockwise or counterclockwise, and parts are turned thereupon; Can loosen two handles afterwards, torsion spring can open two calipers, thereby takes out slip-joint pliers.

The beneficial effect of the utility model is: the utility model on the basis of conventional slip-joint pliers, set up one open binding clip torsion spring, make that repair work is accomplished after; Binding clip can open automatically; Reduced operating personnel's workload, it is comparatively convenient to use, and the utility model is simple in structure, compact; Low production cost is made easily.

Fig. 2 is the structural representation of looking up of the utility model.

Fig. 3 is the enlarged diagram of A portion among Fig. 2.

The specific embodiment

Below in conjunction with Figure of description, the utility model is described further.

As shown in Figure 1, a kind of slip-joint pliers comprise that two calipers, 1, two caliper that is hinged forms two binding clips 6 of symmetric arrangement along a side of jointed shaft, are shaped on the big gearing part 5 that is used for clamping pancake or cylindrical component and little tooth portion 7 on the said binding clip; Caliper extends to form two handles 2 of symmetric arrangement along the opposite side of jointed shaft 3.

Said jointed shaft passes through behind two hinge holes on two calipers by nut 8 lockings, also is shaped on an adjustment hole 4 on the caliper wherein, and said adjustment hole is communicated with (conventional structure is not described in detail) with hinge hole on this caliper through chute.Said jointed shaft is a T shape structure, and its main part is processed the cylinder that cross section is an oval shape; When accessory size was big, jointed shaft can slide along said chute and slide to the adjustment hole from hinge hole, made jaw open more wide-angle to adapt to accessory size.

Said structure of the utility model and conventional slip-joint pliers are similar, and the improvement part of the utility model is following.

The utility model offers respectively in opposite directions and right mounting groove 10 on two calipers; Two mounting grooves are positioned at the hinge hole place; There is a torsion spring 9 to be sleeved on the jointed shaft; And it is interior so that two calipers are applied moment of torsion that the two ends of torsion spring are resisted against two mounting grooves respectively, and binding clip can open automatically after the feasible work that completes repairs.

The utility model is simple in structure, compact, and is easy to use, can reduce operating personnel's workload, and low production cost, makes easily.
