Abstract

The utility model relates to a pair of hardware tool pliers. The utility model comprises two plier bodies, and each plier body is provided with a handle and a plier cheek; the plier cheek of one plier body penetrates in a hole of the plier cheek of the other plier body; the junction of the two plier cheeks is provided with a shaft pin, the penetrating plier cheek rotates around the shaft pin, and the penetrating plier cheek is fixedly connected with the shaft pin; spring sheets are respectively arranged on the handles of the two plier bodies, and the two spring sheets contact in an opposite contact type. The utility model has the advantages of flexible rotation, large opening angle, difficult rustiness, long service life, etc. The utility model is mainly suitable for the radio industry, the electronic industry, the instrument industry, etc.

Description

Hardware pliers

The utility model relates to a kind of Hardware pliers, relates in particular to the telecommunication gripper clamp and the cutting nipper of industries such as being applied to radio, electronics, instrument.

The pincers cheek of traditional Hardware pliers all adopts the embedding superposing type, be by about the pincers cheek of two calipers embed the stack back mutually and connect by middle bearing pin, the pincers cheek and the bearing pin of one of them caliper are fixed, and the pincers cheek of another caliper can rotate around fixed pin shaft after embedding.This Hardware pliers by the operator grasps handle, according to different requirements, carries out clamping, reverses or shears in use.This Hardware pliers is simple in structure, manufacturing and use are also more convenient, but in use mainly there is following shortcoming: 1, embed superposing type because the pincers cheek of caliper adopts, if pliers for a long time need not, make embedding place of pincers cheek that corrosion takes place easily, and make the pliers rotation dumb, adding lubricating oil then has dirty oil to emerge later on, influences outward appearance; 2, the power overwhelming majority that is subjected in use of this pliers acts on bearing pin, and it is loosening that the bearing pin distortion is produced, thereby causes the performance of pliers to reduce reduction of service life.

The purpose of this utility model is, a kind of Hardware pliers is provided, and it can obviously reduce the suffered active force of bearing pin, improves flexibility and service life when using.

This realizes above-mentioned purpose, the technical solution of the utility model is, a kind of Hardware pliers, comprise two calipers, each caliper all has handle and pincers cheek, it is characterized in that: the pincers cheek of one of them caliper is through in the hole of another one caliper pincers cheek, in the phase junction of two pincers cheeks one pivot pin is arranged, the pincers cheek that penetrates rotates around pivot pin, and the pincers cheek that is threaded into is fixedlyed connected with pivot pin; On the handle of two calipers, be separately installed with a spring leaf.

The utility model has the advantages that: after 1, adopting pincers cheek through type structure, the flexibility in the time of can improving the compactness that cooperates between two pincers cheeks and rotation; 2, the pincers cheek of two calipers is when holding articles, and the suffered reaction force major part of pliers all acts on the caliper, and pivot pin is subjected to reverses, shear force is very little, so can improve the service life of pliers.

Below in conjunction with accompanying drawing the utility model is described in further detail.

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

Fig. 2 is the left diagrammatic sketch of Fig. 1;

Fig. 3 is the A-A profile of Fig. 1.

By Fig. 1, Fig. 2 and Fig. 3 as can be known, the utility model comprises first caliper 3 and second caliper 8, handle 5, pincers cheek 2 and clamp head part 1 are arranged on first caliper 3, handle 6, pincers cheek 10 and clamp head part 11 are arranged on second caliper 8, have a hole in the pincers cheek 2 on first caliper 3, pincers cheek 10 on second caliper 8 passes this hole, with this hole be matched in clearance; Junction at the pincers cheek 10 of the pincers cheek 2 of first caliper 3 and second caliper 8 is provided with a pivot pin 9, pivot pin 9 is fixedlyed connected with the pincers cheek 2 of first caliper 3, the pincers cheek 10 of the pivot pin 9 and second caliper 8 flexibly connects, pincers cheek 10 can rotate around pivot pin 9, because the pincers cheek 10 of second caliper 8 is in the hole of the pincers cheek 10 that is rotated in first caliper 3 of pivot pin 9, so speed ratio is more flexible.Be separately installed with spring leaf 4 and 7 on the handle 5 of first caliper 3 and on the handle 6 of second caliper 8, spring leaf 4 and 7 contact and be the formula of crashing open two

handles

5 and 6 automatically under situation about not stressing.

The utility model in use, the pincers cheek 10 of operator grasps two

handles

5 and 6, the second calipers 8 rotates around pivot pin 9, makes two clamp head parts 1 and 11 clamp, reverse or shear article, the reaction force of article mainly acts on two

calipers

3 and 8, and the suffered reaction force of pivot pin 9 is very little.After unclamping hand, under the effect of spring leaf 4 and 7, open automatically.

Claims

1, a kind of Hardware pliers, comprise first caliper and second caliper, handle and pincers cheek are all arranged on first caliper and second caliper, it is characterized in that: have a hole on the pincers cheek (2) of described first caliper (3), the pincers cheek (10) of second caliper (8) passes this hole, and with this hole be matched in clearance, junction at two pincers cheeks (2) and (10) is provided with a pivot pin (9), pivot pin (9) is fixedlyed connected with the pincers cheek (2) on first caliper (3), and pivot pin (9) is gone up pincers cheeks (10) with second caliper (8) and flexibly connected.

2, Hardware pliers according to claim 1 is characterized in that: be separately installed with spring leaf (4) and (7) on the handle (5) of described first caliper (3) and second caliper (8) and (6).
