Description

A kind of all insulation needle-nose pliers

Technical field

This utility model relates to pliers technical field.

Background technology

Pliers is the instrument that it is frequently necessary in life or production process use, and most commonly used, pliers has multiple types Type, common pliers have Jian Zui, Ping Zui, twitch one's mouth, circle mouth etc., but either in life or market, there is no a kind of pliers Being all insulation, especially in electrical network distribution facility, it is often necessary to livewire work, needing to use pliers, so needing now Want a kind of can the pliers of all insulation, it addition, from the point of view of for pliers, the activity of itself between two clamp handles being mutually rotationally connected Degree determines the most handy convenience of pliers, say, that if in the presence of not having grip, if two clamp handles it Between interaction force less if, can become relatively the loosest between two clamp handles, if the phase interaction between two clamp handles If firmly big, become ossifing very between two clamp handles, be namely difficult between two clamp handles of grasp of freedom and flexibility Folding, this interaction force be by clamp handle between exposure level determine, and pliers has been determined after producing Type, is difficult to change, but with when different places may use the pliers of different contact dynamics, if so can be by two Effect dynamics between individual clamp handle becomes adjustable, then significantly facilitate practicality.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of all insulation needle-nose pliers, this pliers not only all insulation, and And interaction dynamics between two clamp handles is adjustable, can grasp and regulate mutually rotate between two clamp handles flexible flexibly Degree.

For solving the problems referred to above, this utility model adopts the technical scheme that: a kind of all insulation needle-nose pliers, right including two Claiming to arrange and the identical clamp handle one of structure and clamp handle two, described clamp handle one and clamp handle two include handle and jaw, clamp handle one respectively Handle and the intersection of jaw be fixedly connected with rotating shaft, the handle of clamp handle two and the intersection of jaw and be provided with through hole, described turn Axle is through described through hole being rotationally connected with clamp handle two, and described rotating shaft is stretched out after through hole with bared end, described bared end length For 5mm to 8mm, being respectively provided on two sides with an elastic steel strip at bared end, described bared end connects with two elastic steel strips respectively Touching and be clipped between two elastic steel strips, one end of said two elastic steel strip is connected and fixes with clamp handle two, said two bullet The other end of property steel bar connects a stay cord respectively, is additionally provided with and regulates elastic steel strip pair for pulling stay cord in clamp handle two The governor motion of bared end contact dynamics.

Preferably, described governor motion includes guiding the rope-winding wheel being rotationally connected wheel with clamp handle two, and described stay cord is from leading Passing to between wheel, the center of described rope-winding wheel is fixedly connected with the center-pole that cross section is square shape, on center-pole Being provided with the loop bar that shape is suitable and can move along center-pole length direction, described loop bar is fixedly connected with for ordering about wiring The action bars that wheel rotates, at multiple kelly that is provided around of rope-winding wheel, described kelly along action bars rotate time its rod end shifting Dynamic track is evenly arranged.

Preferably, described clamp handle one and clamp handle two are all laid with the insulating barrier that makrolon material is made, Steel wire is accompanied in insulating barrier.

This utility model is had the effect that, this pliers has the effect of all insulation, and inside is provided with steel wire, not only All insulation, and add the dynamics of insulating barrier, it is simple to hand-held operation, and degree of flexibility in relative rotation between two clamp handles Can effectively regulate, facilitate the use of different places.

Detailed description of the invention

With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings: as shown in Figure 1, Figure 2 and A kind of all insulation needle-nose pliers shown in Fig. 3, is symmetrical arranged including two and clamp handle 1 that structure is identical and clamp handle 22, described pincers Handle 1 and clamp handle 22 include that handle and jaw, the handle of clamp handle 1 and the intersection of jaw are fixedly connected with rotating shaft 3 respectively, The handle of clamp handle 22 and the intersection of jaw are provided with through hole, and described rotating shaft 3 through described through hole and is rotationally connected with clamp handle 22, Described rotating shaft 3 is stretched out after through hole with bared end, a length of 5mm to the 8mm of described bared end, being respectively provided on two sides with at bared end One elastic steel strip 4, described bared end contacts and is clipped between two elastic steel strips 4 with two elastic steel strips 4 respectively, and described two One end of individual elastic steel strip 4 is connected and fixes with clamp handle 22, and the other end of said two elastic steel strip 4 connects one respectively and draws Rope 5, is additionally provided with in clamp handle 22 and regulates the elastic steel strip 4 regulation machine to bared end contact dynamics for pulling stay cord 5 Structure.

Governor motion includes guiding the rope-winding wheel 7 being rotationally connected wheel 6 with clamp handle 22, and described stay cord 5 is from guiding wheel 6 Between pass, the center of described rope-winding wheel 7 is fixedly connected with the center-pole 8 that cross section is square shape, is provided with on center-pole 8 Shape is suitable and the loop bar 9 that can move along center-pole 8 length direction, and described loop bar 9 is fixedly connected with for ordering about wiring The action bars 10 of wheel 7 rotation, at multiple kelly 11 that is provided around of rope-winding wheel 7, described kelly 11 along action bars 10 rotate time The motion track of its rod end is evenly arranged.

Described clamp handle 1 and clamp handle 22 are all laid with the insulating barrier that makrolon material is made, at insulating barrier Inside accompany steel wire.

This insulated pliers as Figure 1-3, the surface of this pliers is all laid with a strata carbonate material and is made Insulating barrier, it is achieved that all insulation, applicable electrical network power distribution construction very uses, and is provided with steel wire inside insulating barrier, rises Arrive to the effect of soft insulating barrier reinforcement, added dynamics.

Additionally this pliers is with governor motion, and degree of flexibility in relative rotation between scalable two clamp handle, when two elasticity Steel bar 4 is pullled the when of drawing close to centre, and two elastic steel strips 4, by the bared end clamping of middle rotating shaft 3, increase friction Power so that what clamp handle 22 phase countershaft 3 rotated puts more effort, namely makes between two clamp handles flexibility ratio fall in relative rotation Low, with should the dynamics of pullling of stay cord 5 be released when, two elastic steel strips 4 reduce with the contact force of bared end, then two Between individual clamp handle, flexibility ratio increases in relative rotation.

And pullling and discharging of stay cord 5 is realized by governor motion, loop bar 9 is lifted up, rotating operation bar 10, Making rope-winding wheel 7 rotate, be wound around by stay cord 5, after rotateing in place, fallen by loop bar 9, action bars 10 is also fallen simultaneously, will operation Bar 10 is stuck between two kellies 11, guides and wheel 6 is served the guide effect to stay cord 5.
