Abstract

The utility model relates to a universal pincers belonging to the hand tool field, comprising a handle and a C-shaped head. The utility model is characterized in that one end of the handle is in an arch shape, and saw tooth stripes are arranged on the arch surface; saw tooth stripes are arranged on the incurve of the C-shaped head which is connected with one arch-shaped end of the handle through a rotating shaft; the acting force point of the arch-shaped surface of the handle, the incurve of the C-shaped head and screw fasteners at least has three. The utility model having the advantages of simple structure and low cost is not only suitable for various screw fasteners with regular shapes, but also is suitable for various wearing screw fasteners with irregular shapes.

Description

A kind of combination pilers

The utility model relates to a kind of instrument pincers, and particularly a kind of combination pilers belong to field of hand.

Spanner, plumbing combination pliers all are to utilize lever principle to twist bolt, screw, nut and other threaded fasteners.Spanner is divided into fork spanner and adjustable wrench, and fork spanner is shaped on the opening or the trepanning of grip bolt or nut in handle one or both ends all, and adjustable wrench is the end opening at handle, and the width of opening can be regulated in the certain size scope.The spanner of prior art acts on the force of threaded fastener and has only two, can only have an effect to the intact threaded fastener of shape, when threaded fastener suffered wearing and tearing to cause out-of-shape, the spanner of prior art or plumbing combination pliers will skid, even can not have an effect.

The purpose of this utility model provides a kind of combination pilers, and these combination pilers are simple in structure, can clamping the Any shape threaded fastener, and it is screwed or unscrews.

The purpose of this utility model can take following measure to reach: a kind of combination pilers, comprise handle and C shape head, its design feature is: an end of handle is curved arch, cambered surface is provided with hackle mark, the interior curved hackle mark that is provided with of C shape head, C shape head is connected by the end that rotating shaft and handle are curved arch, and can freely rotate along rotating shaft.

The purpose of this utility model can also take following measure to reach: the root of C shape head has a groove, and the width of groove is suitable with the thickness of handle, and it can be 5 °～150 ° free movement in a curve along rotating shaft as radian that the degree of depth of groove makes C shape head.

The interior curved hexagon that is of C shape head, one of them drift angle and adjacent with it limit are removed, and form the opening of C shape head.

The interior curved dodecagon that is of C shape head, wherein two angles and adjacent with it limit are removed, and form the opening of C shape head.

The acting in conjunction force of the interior curved double thread securing member of the cambered surface of handle, C shape head has three at least.

Compared with prior art, the utlity model has following outstanding advantage;

1, not only can rotate the threaded fastener of regular shape, and can rotate the threaded fastener in irregular shape that weares and teares, is out of shape.

2, the opening of combination pilers can be regulated automatically with the size of threaded fastener, need not add other spare and accessory parts.

3, simple in structure, with low cost, sturdy and durable.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is the partial sectional view of the C shape head of the utility model embodiment 1.

Fig. 1, Fig. 2 constitute embodiment 1 of the present utility model.As can be seen from Figure 1, the utility model is formed by connecting by rotating shaft 3 by handle 1, C shape 2, and the head of handle 1 is curved arch.Cambered surface is provided with hackle mark, C shape 2 is hexagon, one of them drift angle and two limits adjacent with this drift angle are removed the opening that forms C shape head, interior bent face is provided with hackle mark, the root of C shape 2 has a groove 4, the thickness of the width of groove 4 and handle 1 is suitable, and the degree of depth of groove 4 control C shape 2 does freely along rotating shaft that camber line rotates, and radian is 10 °～120 °.

As can be seen from Figure 1, the utility model is owing to the head of handle 1 is curved arch and is provided with hackle mark, bend in the C shape head and be hexagon and be provided with hackle mark, therefore, no matter the shape of threaded fastener is hexagon, square, circular or other regular, irregular shapes, as long as its size is in the gripping range of combination pilers, the contact point of itself and combination pilers will have three at least, and along with the increase of the active force of the tail end that puts on handle, the holding capacity of this contact point also increases, and combination pilers double thread securing member can hold tight more.Therefore, the shape of threaded fastener rule whether no matter, the distortion that whether is worn, the utility model is the same can tighten or unscrew this threaded fastener smoothly.C shape head is movement in a curve along rotating shaft 3, and the angle of itself and handle changes between 10 °～120 °, so the utility model can both be had an effect to the threaded fastener of different size.

Embodiment 2 of the present utility model is, the interior curved of C shape 2 is dodecagon, and its radian that moves along rotating shaft 3 is 5 °～150 °, and all the other are with embodiment 1.
