Detailed description of the invention

Below in conjunction with the accompanying drawings, specific embodiments of the present utility model is described in detail.

A kind of pliers as shown in Figure 1, including two calipers 2 intersecting hinged by hinge 1, caliper 2 includes position In the binding clip 201 of front end, it is positioned at the clamp handle 203 of rear end, and is positioned at middle part, for connecting binding clip 201 and the connection of clamp handle 203 Body 202, two connectors 202 are overlapped, and described hinge 1 passes perpendicularly through two connectors 202 and realizes hinged, described two connectors Being respectively arranged with upper groove 3 facing each other and low groove 4 on 202 faces in opposite directions, described hinge 1 is through upper groove 3 and recessed Groove 4, upper groove 3 and low groove 4 are harmonious and form spring cavity 5, are provided with torsion spring 6 in spring cavity 5, and torsion spring 6 includes torsion spring main body 601 Be positioned at the toggle 602 at torsion spring main body 601 two ends, torsion spring main body 601 is set on hinge 1, and two toggles 602 are respectively with upper The cell wall of groove 3, the cell wall of low groove 4 offset, and the elastic force of described torsion spring 6 drives two binding clips 201 to be in not by external force time Open state.

When user clamping pliers makes, and torsion spring 6 is in force and deformation state, is applied in clamp handle 203 when user comes loose Power time, torsion spring 6, under its twisting force, drives two binding clips 201 automatically to separate, thus realizes the pincers that are made up of two binding clips 201 The technical goal that mouth automatically opens up.

Described upper groove 3 includes the upper bar being connected with upper cannelure 301 around the upper cannelure 301 of hinge 1 with one end Shape groove 302, described torsion spring main body 601 is positioned at cannelure 301, and the toggle 602 of torsion spring 6 upper end is stuck in bar-shaped trough 302 In；Described low groove 4 includes the lower bar-shaped trough being connected with lower cannelure 401 around the lower cannelure 401 of hinge 1 with one end 402, the toggle 602 of described torsion spring 6 lower end is stuck in lower bar-shaped trough 402.When the toggle 602 of torsion spring 6 is stuck in upper bar Time in shape groove 302 and lower bar-shaped trough 402, determined that pliers when without external force state, the opening angle of two binding clips 201, prevent Two binding clip 201 opening angles are excessive, cause two clamp handle 203 excessive separation, the situation that the hands of user cannot be taken hold of.

The periphery of described upper cannelure 301 is provided with the annular gathering sill 7 concentric with hinge 1, described lower cannelure 401 Periphery be provided with the round ring guide 8 matched with gathering sill 7.During installation, guide rail 8 embeds in gathering sill 7, can be to two pincers Body 2 play the guiding role when rotating, additionally it is possible to prevent the butter in spring cavity 5 from leaking.

It is rear end that described binding clip 201 connects one end of connector 202, and the other end is front end, on two binding clips 201 face in opposite directions Be respectively symmetrically from rear end forward end be provided with for shearing tinsel blade 9, along the axially extended arcuate groove of hinge 1 10, Some along hinge 1 axially extended wire stripping groove 11 and some along the axially extended little rake tooth 12 of hinge 1, described arcuate groove 10 Wall on be evenly equipped with some axially extended big rake tooths 1001, described little rake tooth 12 is aligned to the front end of binding clip 201 always. Arcuate groove 10 can be used for binding nut and turns, and the wall of arcuate groove 10 is provided with axially extended big rake tooth 1001, Can prevent nut from sliding in arcuate groove 10, wire stripping groove 11 is for clamping the electric wire of electro-insulating rubber, by electro-insulating rubber from electric wire Upper stripping, arranges little rake tooth 12 and can prevent workpiece from slipping during gripping.

The acute angle theta that the axis of symmetry a of described two the binding clips 201 and axis of symmetry b of two clamp handles 203 is formed 20 degree to 30 degree it Between.Generally the hands of people is when using pliers, and wrist can bend, and uses pliers can make the wrist discomfort of people for a long time, and above-mentioned Technical scheme can be effectively improved the user economy combination pliers period of the day from 11 p.m. to 1 a.m, the degree of crook of wrist, makes user use pliers for a long time also Will not feel that wrist is uncomfortable.

In actual use, in order to improve the metacarpus comfort level of user, in described clamp handle 203, the sheathed tool of meeting is resilient Cover of pliers handle 204.

Operation principle of the present utility model is: utilize torsion spring to drive two binding clips to be automatically separated, when making pliers use more The most convenient.
