Description

Capillary pipe wrench

Technical field

The utility model relates to a kind of pipe wrench, particularly relate to a kind of low cost of manufacture, facilitate handy, mouth of pipe cut quality is good, the capillary pipe wrench of long service life.

Background technology

The claw beam that capillary pipe wrench is generally hinged by two panels forms, the jaws that can clamp capillary is provided with again at the jaws end of two claw beams, that clamps capillary by jaws during use cuts off position, carrying out back rotation capillary again makes capillary outer wall mark circle tool marks, take out the two ends that both hands after capillary hold cut to pull and can disconnect capillary, can directly use without the need to line up reprocessing.But existing pipe wrench claw beam mostly adopts monoblock type metal sheeting design, and not only manufacturing cost is high, weight is large, and service life is short, and mouth of pipe cutting is wasted time and energy, of poor quality.

Summary of the invention

The utility model mainly provides a kind of low cost of manufacture, it is handy to facilitate, mouth of pipe cut quality is good, the capillary pipe wrench of long service life, solve that the pipe wrench manufacturing cost existed in prior art is high, service life is short, mouth of pipe cutting wasted time and energy, technical problem of poor quality etc.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of capillary pipe wrench, comprise the left clamp arm hinged in " X " shape and right clamp arm, one end horizontal-extending of left clamp arm and right clamp arm forms handle end, other end horizontal-extending forms the jaws end that interworking is sheared, on a left side, on the shear surface of right two jaws ends, corresponding being provided with can clamp and cut the semicircle cutting edge of capillary, described handle end is outward extended with handle strut, the medial extremity of handle strut is located on handle end, and on the lateral surface of handle strut opposition, be embedded with elasticity shake hands pad.By on a left side, the extended handle strut of handle end of right clamp arm, namely handle changes split-type structural into by original monolithic construction, the two can adopt different materials thus, as handle strut adopts lightweight, overall weight and the cost of pipe wrench can be reduced during the low material of cost, left, right clamp arm adopts the alloy material that the performance such as wearability and toughness is good, thus extend its service life, facilitate handy simultaneously, and ensure that mouth of pipe cut quality, again due to pad of shaking hands in the lateral surface setting-in elasticity of handle strut, hold during use elasticity shake hands pad force, comfortableness is good, easy force, make cutting processing more time saving and energy saving.

As preferably, described handle strut is PP engineering material, and the injection mo(u)lding of handle strut is on handle end.Adopt PP engineering material and handle end injection mo(u)lding, intensity is high, and manufacturing cost is with the cost of material is low.

As preferably, on described elasticity shakes hands pad, be provided with some strip grooves, and strip groove extends along the length direction of handle strut.The strip groove that elasticity is shaken hands on pad can increase frictional force, prevents force from skidding.

As preferably, the shear surface linearly shape of described jaws end, semicircle cutting edge is located at the middle part of shear surface, and the shear surface corresponding to semicircle cutting edge both sides slopes inwardly and forms domatic cutting edge.By going out domatic cutting edge in the shear surface machine-shaping of semicircle cutting edge both sides, shearing other part by two sections of domatic cutting edges, namely serving as scissors temporarily and using, extending its using function.

As preferably, between the handle strut of close described left clamp arm and right clamp arm rotating shaft, be provided with stage clip.Stage clip makes left and right tong arm Automatic-expanding after Pipe Cutting, time saving and energy saving.

L shape limited block can be rotatably connected on right clamp arm, as preferably, left clamp arm handle end near left clamp arm and right clamp arm rotating shaft is rotationally connected one end of L shape limited block, it is outer and extend towards jaws extreme direction that the other end of L shape limited block extends to handle strut, the right clamp arm corresponding with L shape limited block is provided with the wedge angle boss of interworking, when left and right two jaws ends shear docking, L shape limited block upwards rotates and is connected on wedge angle boss.By arranging L shape limited block, when preserving and rotatable L shape limited block be upwards connected on wedge angle boss, thus limit the relative position of left and right tong arm, reduce profile space, convenient for collecting; Rotate L shape limited block during use can unlock downwards, structure is simple, safe and reliable.

Instrument suppending hole can be located on left clamp arm, and as preferably, the handle strut outboard end corresponding at described right clamp arm is provided with instrument suppending hole.Instrument suppending hole facilitates hanging to deposit.

As preferably, described elasticity shakes hands pad for TPR thermoplastic rubber material.TPR thermoplastic rubber material good springiness, during hand-held use, comfortableness is high.

As preferably, described left clamp arm and right clamp arm are 5Gr13 stainless steel material.5Gr13 stainless steel material has hardness high (>60HRC) after quenching, wearability is splendid, and there is good toughness and splendid corrosion resistance, therefore sharp relative to the traditional structure edge of a knife, capillary otch full-quality is good, pipe wrench is durable in use, long service life.

Therefore, a kind of capillary tonger of the present utility model has following advantage: handle changes split-type structural into, thus when handle strut adopts lightweight, significantly can reduce overall weight and the cost of pipe wrench during the low material of cost, elasticity is shaken hands simultaneously, and pad is convenient to exert a force, and comfort is good; Be adopted as TPR thermoplastic elastomer and handle end injection mo(u)lding, intensity is high, and cost is low; By arranging L shape limited block, when preserving and rotatable L shape limited block be upwards connected on wedge angle boss, thus limit the relative position of left and right tong arm, reduce profile space, convenient for collecting; Left clamp arm and right clamp arm adopt 5Gr13 stainless steel material, and the edge of a knife is sharp, and capillary otch full-quality is good, and pipe wrench is durable in use, long service life.
