Description

Roll over silk pincers

Technical field

Tool tong is the utility model is related to, is specially a kind of folding silk pincers, for copper wire to be carried out into 90 degree of bendings.

Background technology

Pliers be it is a kind of be used to clamping, fixed workpieces processing or torsion, bending, the hand tools for cutting tinsel. Pliers generally includes clamp handle, the pincers cheek（Articulated section）And binding clip（Clamping part）Three parts.The species of pliers is various, specifically there is sharp mouth Pincers, diagonal cutting nippers, cutting pliers, curved nozzle pincers, pliers, needle nose pliers, bolt clipper, locking pliers, pipe vice, perforating plier etc..

At present, for common cutting pliers, it is a kind of clamp and cutting implement, is made up of binding clip and clamp handle, binding clip includes Jaw, tooth mouth, the edge of a knife and hand hay cutter mouth.The effect at each position of pliers is：1. tooth mouth can be used to fasten or unscrew nut；2. the edge of a knife It can be used to the rubber or plastic insulating layer of cutting cord, it is also possible to shear electric wire, iron wire；3. hand hay cutter mouth can be used for cutting off electricity The harder metal wire such as line, steel wire；4. pressure-resistant more than the 500V of insulated plastic expects pipe of pliers, there is it can be with powered shearing electric wire. In use, never throw out without care.In order to avoid damage insulated plastic expects pipe.The cutting pliers that electrician commonly uses are by 150mm, 175mm, 200mm and 250mm Etc. plurality of specifications.

But the copper cash progress being frequently necessary to for electric operating personnel in power industry more than pair cross-section 2.5mm2 is curved Folding, it is currently that worker carries out manual operations, i.e. a hand bites copper cash using cutting pliers, and it is artificial that another hand catches copper cash to carry out Bending, it usually needs spend suitable great strength to complete；It is exactly that copper wire is bent using two cutting pliers, operates Inconvenience, efficiency are low.

The content of the invention

The purpose of this utility model is to provide a kind of broken line pincers for being used to bend copper cash, being capable of singlehanded easy manipulation broken line Pincers, realize 90 degree of bendings of copper cash.

The utility model adopts the following technical scheme that realization：

One kind folding silk pincers, including left clamp and right clamp；The right clamp end is extended with broken line segmental arc；The broken line arc Section is used to the copper cash being clamped between left clamp and right clamp bending 90 degree during occlusion.

During concrete operations, the twisting part of copper cash one end insertion broken line pincers, the right hand are closed left and right clamp handle by left hand, then positioned at a left side During copper cash between clamp and right clamp is bent by straight line to 90 degree, now bending of the termination of left clamp against copper cash Point inner side, the termination of broken line segmental arc is against the inflection point outside of copper cash, and copper cash is using the termination of left clamp as bending fulcrum, left and right pincers Press from both sides in closing course, under the position-limiting action of broken line segmental arc termination, left clamp termination drives the inflection point of copper cash by broken line segmental arc Termination be moved to the root of broken line segmental arc, then copper cash is taken advantage of a situation 90 degree of bending.

The utility model is designed reasonably, electric operating personnel being capable of the light pair cross-section 2.5mm of one-handed performance broken line pincers²More than Thick copper lines carry out 90 degree bendings, reduce the operation intensity of personnel, raising operating efficiency, there is good application value.

Brief description of the drawings

Fig. 1 represents that copper wire is bent preceding schematic diagram.

Fig. 2 represents that copper wire is bent to 90 degree of schematic diagrames.

In figure：The right clamp handles of 1-, 11- articulated sections, the left clamps of 12-, 13- broken line segmental arcs, the left clamp handles of 2-, the right clamps of 22-, 3- copper Silk.

Embodiment

Specific embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

One kind folding silk pincers, including left clamp 22 and right clamp 12；The end of right clamp 12 is extended with broken line segmental arc 13；Institute Broken line segmental arc 13 is stated to be used to the copper cash 3 being clamped between left clamp 22 and right clamp 12 bending 90 degree during occlusion.

Specific when preparing, for the right clamp 12 than left 22 long 0.3-0.8mm of clamp, right clamp 12 is slightly longer than left clamp 22, It can cause the kink of copper cash that 90 degree of bendings easily occur under the cooperation of broken line segmental arc termination and left clamp termination.

The chord length 4-6cm of the broken line segmental arc 13, broken line segmental arc moderate length is too short then relatively elaborate, it is oversize then It is not necessary to waste of materials.

During concrete operations, the twisting part of the one end of copper cash 3 insertion broken line pincers, the right hand are closed left clamp handle 1 and right clamp handle by left hand 2, then during the copper cash 3 between left clamp 22 and right clamp 12 is by straight line to 90 degree of bendings, now left clamp 22 Termination is against on the inside of the inflection point of copper cash 3, and the termination of broken line segmental arc 13 is against on the outside of the inflection point of copper cash 3（As shown in Figure 1）, copper Line 3 is spacing in the termination of broken line segmental arc 3 in left and right clamp 22,12 closing courses using the termination of left clamp 22 as bending fulcrum Under effect, the left termination of clamp 22 drives the inflection point of copper cash 3 to be moved to the root of broken line segmental arc 13 by the termination of broken line segmental arc 13, And the termination of copper cash 3 is motionless by the root occlusion of left and right clamp 22,12, then copper cash 3, which is taken advantage of a situation, bends 90 degree（As shown in Figure 2）.

Broken line pincers described in the utility model are that the termination of a clamp is extended wherein on the basis of ordinary steel wire pincers Broken line segmental arc, the broken line segmental arc is towards another clamp, it is generally the case that the broken line segmental arc is a minor arc, material and cutting pliers Material is identical or different, and broken line segmental arc is integrally formed with clamp, lifts durability, can also be formed by welding, to existing Cutting pliers directly transform composition.

Above example is merely to illustrate the technical solution of the utility model and unrestricted, although with reference to preferred embodiments to this Utility model is described in detail, and enters it will be appreciated by those skilled in the art that the technical solution of the utility model can be used for reference Row modification or equivalent substitution, without departing from it is of the present utility model in a word and scope, be regarded as being included in of the present utility model Within right.
