Description
Technical field
The utility model relates to one and cuts, particularly a kind of snips.
Background technology
Shear the snips of iron wire, generally comprise two handles and be arranged on the shear blade of two handle front ends respectively, two shear blade are hinged and shear iron wire by the cooperation of its blade.Because the general hardness of iron wire is larger, so, according to mechanics principle, spend less power that shear blade just can be made to produce enough large shearing force to make user iron wire is cut off, handle generally need arrange longer, and the handle of existing snips is generally the structure that can not stretch, because length is comparatively large when not using, larger space can be taken.In addition, because iron wire is comparatively hard, when shearing thicker iron wire, iron wire easily skids off forward along two shear blade, thus can not, by its quick shearing, at this moment, need staff to be caught by this iron wire to carry out auxiliary shearing, but this mode efficiency is low.
Summary of the invention
The purpose of this utility model be to provide a kind of can the snips of THE ADIABATIC SHEAR IN iron wire, its telescopic handle, can reduce space shared when snips does not use.
A kind of snips described in the utility model, comprise two handles, and two shear blade be hinged, described handle is made up of with the movable front bar inserted in rear bar the tubulose rear bar of back-end closure, the front portion of rear bar inwall and the rear portion of front bar outer wall be oriented interior and outside inward flange and outward flange respectively, inward flange and outward flange there is the screw thread matched, the outer wall at front bar rear portion and the inwall of rear bar front portion are separately installed with the sealing ring offseted with the inwall of rear bar and the outer wall of front bar, two shear blade are made up of wolfram steel, the blade of a shear blade is provided with depression sword, the blade of another shear blade is provided with convex sword in the position in correspondence depression sword front, front bar is threaded with the rocking arm of shear blade.
The beneficial effect of snips described in the utility model is: the front bar that 1, its handle is inserted in rear bar by tubulose rear bar and activity forms, before using, after first front bar being pulled out certain length from rear bar, relatively, rod twisting front bar is connected to both inward flanges with outward flange threaded engagement, can use; And when not using, then, after turn-back front bar to inward flange is separated with outward flange, front bar is pushed back in rear bar, significantly can reduce the length of handle, reduce the space shared by snips.2, its shear blade adopts high rigidity wolfram steel to make, simultaneously, the blade of a shear blade is provided with depression sword, and be provided with convex sword in the position in the blade correspondence depression sword front of another shear blade, when shearing iron wire, iron wire first slips in depression sword, by depression sword, iron wire is tentatively pinned, then stop that iron wire slides forward further by convex sword, so that till depression sword coordinates with the blade of another shear blade and cut off by iron wire, therefore, when the iron wire that shearing is thicker, iron wire need not be caught with auxiliary shearing with hand, can shear efficiency be significantly improved.

Detailed description of the invention
As shown in Figures 1 to 4, described a kind of snips, comprise two handles 1, and two shear blade be hinged 2, described handle 1 is made up of with the movable front bar 12 inserted in rear bar 11 the tubulose rear bar 11 of back-end closure, the front portion of rear bar 11 inwall and the rear portion of front bar 12 outer wall be oriented interior and outside inward flange 111 and outward flange 121 respectively, inward flange 111 and outward flange 121 there is the screw thread matched, the outer wall at front bar 2 rear portion and the inwall of rear bar front portion are separately installed with the sealing ring 4 offseted with the outer wall of the inwall of rear bar 12 and front bar 11, 3, two shear blade 2 are made up of wolfram steel, the blade of a shear blade 2 is provided with depression sword 22, the blade of another shear blade 2 is provided with convex sword 23 in the cave in position in 22 sword fronts of correspondence, front bar 12 is threaded with the rocking arm 21 of shear blade 2.Before using, after first front bar 12 being pulled out certain length from rear bar 11, relative rear bar 11 is reversed front bar 12 to both inward flange 111 and is connected with outward flange 121 threaded engagement, can use; And when not using, then turn-back front bar 12 to inward flange 111 is separated place with outward flange 121, front bar 12 is pushed back in rear bar 11, significantly can reduce the length of handle 1, reduce the space shared by snips.In addition, because the outer wall at front bar 12 rear portion and the inwall of rear bar 11 front portion are separately installed with the sealing ring 4,3 offseted with the outer wall of the inwall of rear bar 11 and front bar 12, can prevent liquid dust etc. from entering rear bar 11 inner, and there is guide effect.
As shown in Figure 1, for better operating snips, at the outer wall of rear bar 11, the little burr (not shown) of protrusion or the fossette (not shown) of depression can be set for the region gripped, to increase the coefficient of friction of rear bar 11 gripping surface, improve the stability gripping rear bar 11.
As shown in Figure 1 and Figure 2, the rear end of described rear bar 11 is connected with bonnet 13 by threaded engagement, by the back-end closure of bonnet 13 by rear bar 11, between the end face of bonnet 13 and rear bar 11, be also provided with sealing ring (not shown), enter from the rear end of rear bar 11 to prevent liquid further.
