Abstract

The utility model discloses a pliers, which comprises left and right pliers bodies. Wherein, the left and right pliers bodies are articulated with each other through rivet, and are fixed with a torsional spring. The left and right pliers bodies are provided with wire stripping knives, press limit mechanisms and wire cutting knives. The utility model overcomes the difficulties that the original pliers is only used for stripping wires and not for cutting wires, and length of wire stripping and the compression joint to the male head is out of control. As the press limit mechanism is replaceable, the utility model has certain replaceable performance, thus is suitable for stripping and cutting wires of telephone line with multi cores, and is also suitable for connecting the male head to the telephone line.

Description

Instrument pincers (2)

The utility model relates to a kind of instrument pincers, refers to that specifically a kind of crimping that is used for tangent line, wire stripping and the male of telephone wire clamps with instrument.

Existing instrument pincers, too many tangent line, the wire stripping that only is used for electric wire also has the instrument of some wire strippings that are used for telephone wire to clamp, but simple in structure, function singleness, can not tangent line, the length of wire stripping can not be controlled, and only be applicable to circle, the wire stripping of single core copper class telephone wire.For flat, multicore copper class telephone wire, and how male is crimped onto on the telephone wire, powerless especially.

The purpose of this utility model is to provide a kind of multi-functional instrument pincers, and it can finish wire stripping, the tangent line of telephone wire, can control the length of wire stripping simultaneously and to the crimping of male.

The purpose of this utility model is achieved in that

A kind of instrument pincers is characterized in that comprising left caliper, right caliper body, and left caliper wherein, right caliper body at one end end is hinged by rivet, and fixes one and turn round a spring, and wire stripping cutter and crimping, position-limit mechanism, tangential knife are installed on left caliper and right caliper body successively.

Aforesaid a kind of instrument pincers is characterized in that the wire stripping cutter has two on blade, and respectively there is a semicircle breach at the two ends of blade, just are stuck in the outside high spot on left caliper and the right caliper body during installation; And fix by screw rod, nut.

Aforesaid a kind of instrument pincers is characterized in that crimping, position-limit mechanism be made up of rubber base, crimp head, and rubber base is fixed on the left caliper; Crimp head is fixed on the right caliper body, on crimp head, be provided with upper holder block and lower lock block, upper holder block is " protruding " shape, there is certain chamfering the back of protruding end, lower lock block also is " protruding " shape, in the middle of the top pointed tooth is arranged, and is provided with groove on rubber base, the shape of groove is corresponding with the external shape of telephone wire male, extends upward a rectangle guide vane end stop on rubber base.

Aforesaid a kind of instrument pincers is characterized in that tangential knife is installed on the right caliper body, just in time is stuck in the depressed portions of right caliper body; Cutting off telephone wire with left caliper uses.

The utility model is installed to tangential knife, wire stripping cutter same as on the instrument pincers, increased a crimping position-limit mechanism simultaneously, be only limited to wire stripping thereby overcome original instrument pincers, and can not tangent line, can not control the length of wire stripping, and to the difficult point of the crimping of male.Because the crimping position-limit mechanism can be changed, and has certain interchangeable performance, is applicable to tangent line, the wire stripping of multicore telephone wire, and male is crimped onto on the telephone wire.

Below in conjunction with accompanying drawing structure of the present utility model is done detailed explanation:

Fig. 1 is a front view of the present utility model

Fig. 2 is a rearview of the present utility model

Fig. 3 is the stereogram of crimping, position-limit mechanism

The utility model comprises left caliper 1, right caliper body 2, wherein left caliper 1, right caliper body 2 at one end end is hinged by rivet, and fixes one and turn round a spring 3, makes left caliper 1 and right caliper body 2 keep open configuration under free state, at left caliper 1, the other end of right caliper body 2 is provided with left and right handle 4, is with taper knob, is convenient to the operator and holds conveniently.

Wire stripping cutter 5 and crimping position-limit mechanism 6, tangential knife 7 are installed on left caliper 1 and right caliper body 2 successively.

Wire stripping cutter 5 has two on blade, and respectively there is a semicircle breach at the two ends of blade, just is stuck in the outside high spot on left caliper 1 and the right caliper body 2 during installation; And fix by screw rod, nut, during work, protect connecing parallelly up and down between the edge of a knife, and certain distance is arranged, be used for peeling off the outer quilt of certain thickness flat, multicore copper class telephone wire.

Tangential knife 7 is installed on the right caliper body 2, just in time is stuck in the depressed portions of right caliper body 2; Making to cut off telephone wire with left caliper 3 uses.

Crimping, position-limit mechanism 6 are made up of rubber base 8, crimp head 9, and rubber base 8 is fixed on the left caliper 1; Crimp head 9 is fixed on the right caliper body 2, is provided with upper holder block 10 and lower lock block 11 on crimp head 9, and upper holder block 10 is " protruding " shape, and there is certain chamfering 12 back of protruding end, and lower lock block 11 also is " protruding " shape, and pointed tooth 13 is arranged in the middle of the top.Be provided with groove 14 on rubber base 8, the shape of groove 14 is corresponding with the external shape of telephone wire male, when making the telephone wire male put into groove, and can be near cell wall.Extend upward a rectangle guide vane end stop 15 on rubber base 8, when guide vane end stop 15 may command left calipers 1 and right caliper body 2 clamped, the front end of telephone wire was with there being certain distance, to guarantee certain wire stripping length between the wire stripping cutter.

The utility model in use,

At first release handle puts in wire stripping cutter 5 with the telephone wire that cuts by the front that instrument clamps, until guide vane end stop 15, and the handle of then holding with a firm grip, the distance between the wire stripping cutter 5 diminishes, and pulls out telephone wire then, so just can obtain the wire stripping of certain-length.

The male of putting on telephone wire is put in rubber base 8 by the front that instrument clamps, insert because the groove 14 of rubber base 8 just is fit to male, thereby have certain guide effect; Make the pointed tooth of upper holder block 11 of crimp head 9 over against the gold plaque of male, the nose of lower lock block 12 is over against the groove of male, pressing handle then, gold plaque puts in the groove under the effect of pointed tooth power, punctures the outer quilt of telephone wire heart yearn, link to each other with heart yearn, thereby form gold plaque with the path between the telephone wire heart yearn, and the distortion that under the effect of lower lock block 12 noses, curves inwardly of the plastics in the groove of male, thereby compress telephone wire quilt outward.
