Abstract

The invention discloses a pair of wire stripping pliers. The wire stripping pliers comprise a left pliers body and a right pliers body, the front end of the left pliers body and the front end of the right pliers body define a pliers jaw, the back end of the left pliers body and the back end of the right pliers body are respectively a left pliers handle and a right pliers handle, a rotatable rolling sleeve is arranged at the middle end of the left pliers handle, an adjustment device is arranged at the middle end of the right pliers handle at the position corresponding to the rolling sleeve, a wire-ripping knife which is rotatably connected with the adjustment device through a pivot is arranged at one end, close to the rolling sleeve, of the adjustment device, and the center axis of the rolling sleeve is perpendicular to the wire-ripping knife. The adjustment device comprises a lead screw and a screw rotary knob, wherein the top end of the screw lead is sleeved with the screw rotary knob. When a cable needs to be replaced, an operator holds the pliers handles, cuts off the damaged cable from two end points with the pliers jaw, enables the cut cable part to penetrate through the rolling sleeve and the middle position of the wire-ripping knife perpendicularly, then rotates the screw rotary knob, conducts fine adjustment on the position of the wire-ripping knife through the lead screw, and strips off the sheath of the cable in the length direction by means of the relative rotation of the wire-ripping knife and the rolling sleeve. The wire stripping pliers are easy to operate, saving in time and labor and capable of ensuring the smoothness of the cut of cable sheath, and do not influence the performance of the cable.

Description

A kind of wire stripping pliers

Technical field

Background technology

In electric power system, a cable sheath often paving is exactly hundreds of rice, sometimes find wherein one section tens meters, when tens meters or the long cables of rice up to a hundred damage to some extent or the sheath of certain partial cables line need to be divested according to the demand in real work, generally first sheath is cut off along the cable hoop, then by artificial hand-held knife, along the length direction of cylindrical cable sheath, it is cut open, this method not only has very large requirement to workman's qualification, and waste time and energy, otch is also disorderly and unsystematic, easily scratch cable and hinder hand, affect construction quality and construction safety.

Summary of the invention

In order to solve the deficiencies in the prior art, the invention provides a kind of simple to operate, time saving and energy saving and do not affect the wire stripping pliers of cable performance.

The objective of the invention is to be achieved through the following technical solutions:

The invention provides a kind of wire stripping pliers, comprise left caliper and right caliper body, described left caliper and described right caliper body are by the straight pin cross-articulation, the part that described left caliper and described right caliper body are positioned at described straight pin front end encloses the formation jaw, the part that described left caliper and described right caliper body are positioned at described straight pin rear end is respectively left pincers handle and right pincers handle, the middle-end of described left pincers handle is provided with rotating roll sleeve, the position of the corresponding described roll sleeve of the middle-end of described right pincers handle is provided with adjusting device, the end that described adjusting device tends to described roll sleeve is provided with takes off the line cutter, the described line cutter of taking off is rotatably connected by pivot and described adjusting device.

Further, described wire stripping pliers also comprise handle, lay respectively at described left pincers the rear end with described right pincers handle.

Further, described adjusting device comprises leading screw and screw knob, and described screw knob sleeve is located at the top of described leading screw.

Preferably, the central shaft of described roll sleeve is with described to take off the line cutter vertical.

Further, the axial both ends of described roll sleeve are provided with respectively guide vane end stop.

Preferably, the length of the central shaft of described roll sleeve equates with the distance between described two guide vane end stops.

Preferably, described left pincers are with right pincers, the part near described straight pin being respectively equipped with to stop block.

Based on disclosing of technique scheme, when needs are changed cable, first holding handle cuts off the cable of damage with jaw from two end points, then the broken parts cable is vertically passed to the roll sleeve position middle with taking off the line cutter, a reserved little transversal head, rotation screw knob again, utilize leading screw to be finely tuned the position of taking off the line cutter until take off the line cutter and roll sleeve all closely is resisted against cable, keep handle not loosening, another pulls the end of a thread, pull cable towards the direction vertical with handle, relatively rotating the strip off along its length of the sheath of cable of line cutter and roll sleeve taken off in utilization.

Described wire stripping pliers provided by the invention are simple to operate, time saving and energy saving and can guarantee that the otch of cable sheath is neat, can not affect the performance of cable.
