Abstract

A pair of pliers belongs to the technical field of hardware tools, and comprises plier heads, plier handles and a rotating shaft, wherein an upper clamping surface and a lower clamping surface of plier mouth parts of the plier heads 1 are clamping curved surfaces (11 and 12) which are arranged vertically and provided with combined and matched concave-convex radians. As the upper flat clamping surface and the lower flat clamping surface of the plier mouth parts are improved to be the upper clamping curved surface and the lower clamping curved surface which are arranged vertically and provided with combined and matched concave-convex radians, and by utilizing the clamping curved surfaces provided with combined and matched concave-convex radians, a clamped object is deformed, and the friction force between the clamping curved surfaces of the plier mouth parts and the clamped object is increased, so that the purpose of firmly clenching the clamped object is realized.

Description

A kind of vice

Technical field:

The utility model relates to a kind of vice, belongs to the hardware ﹠ tools technical field.

Background technology:

Vice is the hardware ﹠ tools of commonly using, and generally is comprised of binding clip and clamp handle.Binding clip has jaw and hand hay cutter mouth usually, holds or cut up with a hay cutter disconnected object for use in stinging to grip.But because the nip part of existing common vice is to be made of upper and lower two straight clamping faces, therefore it is when the columnar object of clamping flat-type object and steel wire class, often easily produce between upper and lower two straight clamping faces of jaw and slide, be difficult to sting tight object.

The utility model content:

The purpose of this utility model be to provide a kind of improved, can firmly sting and grip the vice of holding object.

Its technical scheme is: a kind of vice, comprise binding clip, clamp handle and rotating shaft, and it is characterized in that: have the clamping curved surface that concavo-convex radian coupling combine of upper and lower two clamping faces of described binding clip nip part for vertically arranging.

Its beneficial effect is: due to upper and lower two the straight clamping faces of nip part, be improved to upper and lower two concavo-convex radians that have that vertically arrange and mate the clamping curved surface that combines, the clamping curved surface that utilizes this concavo-convex radian coupling to combine, make the object of clamping produce distortion, increase the frictional force between nip part clamping curved surface and clamping object, thereby realize the clamping object is firmly stung tight purpose.

Description of drawings

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

Fig. 2 is A partial enlarged drawing in Fig. 1.

The specific embodiment

As shown in Figure 1, a kind of vice comprises binding clip 1, clamp handle 2 and rotating shaft 3.Upper and lower two clamping faces of described binding clip nip part mate combine, clamping curved surface 11,12 that be parrot mouth shape for the concavo-convex radian that has that vertically arranges.

Upper and lower two concavo-convex radians that have that vertically arrange of described nip part mate on the clamping curved surface 11,12 that combines, and symmetry is equipped with dentation fine groove 111.

Two concavo-convex radians that have that vertically arrange up and down of described nip part mate the clamping curved surface 11,12 that combines, and are at least one group.

Claims (3)

1. a vice, comprise binding clip, clamp handle and rotating shaft, it is characterized in that: have the clamping curved surface (11,12) that concavo-convex radian coupling combine of upper and lower two clamping faces of described binding clip (1) nip part for vertically arranging.

2. a kind of vice according to claim 1 is characterized in that: upper and lower two having on the clamping curved surface (11,12) that concavo-convex radians coupling combines of vertically arranging of described nip part, symmetry is equipped with the dentation fine groove.

3. a kind of vice according to claim 1 and 2 is characterized in that: described nip part upper and lower two vertically arrange have a clamping curved surface (11,12) that concavo-convex radians coupling combines, be at least one group.
