Abstract

The utility model relates to a manual forceps, in particular to a bending forceps aiming to solve the problems existing in prior art of inadequate shearing force and uneasy nipping off of threading edging caused by the groove body arranged at the forceps head of the forceps body as well as the technical problem that due to the plane of tooth part being parallel to the forceps head, the depth of the teeth inside the groove body is shallow and the shearing plane is inadequate. The utility model comprises an upper forceps body (1) and a lower forceps body (2) articulated with each other, wherein, the forceps body consists of a forceps head and a forceps handle (3); the forceps head (1-1) of the upper forceps body (1) is provided with a groove (1-2) along the direction of the forceps body, while the forceps head (2-1) of the lower forceps body (2) is provided with a convex block (2-2) capable of being inserted into the groove (1-2). The utility model is characterized in that: the upper surface (1') of the forceps head (1-1) of the upper forceps body (1) is a plane.

Description

Folding forceps

Technical field

The utility model relates to a kind of manual pliers, especially relates to a kind of to using the isostructural improvement of folding forceps when office is bound.

Background technology

The structure of pliers and of a great variety respectively has its certain structure, and can realize certain function at present.Generally be used for the combination plier that clamping is crooked and shear, it is that two calipers of being made up of pincers handle and binding clip respectively tighten together by the pincers axle, and combination block and binding clip remainder that clamping face shearing edge in the binding clip and folder circle mouth constitute are flexibly connected by connector.Chinese patent discloses a kind of bookbinding pincers (publication number: CN2794745Y), as Fig. 1, it comprises left half-caliper and right half-caliper that the middle part is mutually hinged, right half-caliper constitutes the jaw part and has groove along caliper, left side half-caliper constitutes the jaw part and is provided with the strip projection along the corresponding groove of caliper, and the projection top is provided with teeth.But the bookbinding of this structure pincers cause shearing force not enough because the clamp head part branch of caliper has cell body, wear edge strip and are not easy to be cut off; And the plane of teeth parts is because parallel with binding clip, and it is more shallow to make that teeth enter the degree of depth of cell body inside, and shear surface is not enough.

Summary of the invention

The purpose of this utility model provides a kind of folding forceps, and it mainly is to solve existing in prior technology bookbinding pincers because clamp head part branch of caliper has cell body, causes shearing force not enough, wears edge strip and is not easy the problem of being cut off; The utility model has also solved the plane of teeth part because parallel with binding clip, and it is more shallow to make that teeth enter the degree of depth of cell body inside, the technical problem of the not enough grade of shear surface.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

Folding forceps of the present utility model, comprise the last half-caliper and following half-caliper that are hinged, caliper is made up of binding clip and pincers handle, the binding clip of last half-caliper has along the groove of caliper direction, but the binding clip of following half-caliper is provided with the projection in the insertion groove, it is characterized in that the described binding clip upper surface of going up half-caliper is the plane.The upper surface of binding clip is the plane, increases the width of binding clip, makes shearing force strengthen.It is inverted "L" shaped structure that the binding clip of following half-caliper and projection are formed section, and projection can enter groove inside when making interlock, and the binding clip of following half-caliper contacts with the binding clip of last half-caliper.

As preferably, the projection on the described half-caliper down is provided with tooth, and the flank of tooth is 1 °～5 ° with the angle α of the binding clip lower surface of following half-caliper.Angle α the best is 3 °, can increase projection and enter the interior degree of depth of groove, makes and shears fully.

As preferably, the described pincers of going up half-caliper and following half-caliper respectively are provided with one to clamping the leaf spring of internal bend last, and two leaf springs are fixed together in its end.Two leaf springs can be affixed by spot welding in the end, makes two leaf springs can not misplace.Pincers on can be with insulation sleeve, fixing leaf spring in the insulation sleeve.

As preferably, be connected with back-moving spring between the pincers of described last half-caliper and the following half-caliper handle.After shearing was finished, the automatic bounce-back of back-moving spring can separate with following half-caliper going up half-caliper again.

Therefore, the clamp head part that the utlity model has caliper is divided into the plane, and thickness is thicker, and shearing force is bigger, wears the characteristics that edge strip is cut off easily; Plane and binding clip that the utility model also has the teeth part have certain angle, and it is darker to make that teeth enter cell body inside, shears characteristics such as comparatively complete, simple and reasonable for structure.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: the folding forceps that this is routine, as Fig. 2, Fig. 3, Fig. 4, a last half-caliper 1 and following half-caliper 2 that is hinged by axle is arranged, and caliper is made up of 3 binding clip and pincers.The binding clip 1-1 of last half-caliper 1 has the groove 1-2 along the caliper direction, and upward the binding clip 1-1 upper surface 1 ' of half-caliper 1 is the plane.But the binding clip 2-1 of following half-caliper 2 is provided with the projection 2-2 in the insertion groove 1-2, and projection 2-2 is provided with tooth 2-3, and as Fig. 2, the flank of tooth is 3 ° with the angle α of the binding clip 2-1 lower surface of following half-caliper 2.It is inverted "L" shaped structure that binding clip 2-1 and projection 2-2 form section.Last half-caliper 1 is with insulation sleeve with the pincers of following half-caliper 2 on 3, respectively be provided with one in the insulation sleeve and to clamping 4, two leaf springs of the leaf spring of internal bend be fixed together by spot welding in its end.

During use, the helical form of bookbinding usefulness is worn the sheared edge that half-caliper 1 and following half-caliper 2 are stretched in the edge strip end.To clamp and close up 3, projection 2-2 and groove 1-2 engagement are worn edge strip and are promptly cut off and bend inwards in fracture place.By the affixed not therefore dislocation of two leaf springs of spot welding.

Embodiment 2: the folding forceps that this is routine, as Fig. 5, the pincers of last half-caliper 1 and following half-caliper 2 are connected with back-moving spring 5 between 3.

All the other are with embodiment 1.
