A spring 415 with pre-pressure is sleeved on the adjusting bolt 412 and positioned between the nut of the adjusting bolt 412 and the boss A412. The positioning device is used for relatively fixing the positions of the two Z-shaped clamp rods 402 of the cutting nipper 4, so that when the two hand-held rods B401 are closed, the adjusting bolt 412 is in contact with the boss B414 to prevent the two Z-shaped clamp rods 402 from further approaching, and the cutting edges of the transverse cutter 404 and the longitudinal cutter 406 cannot be in direct contact with the two V-shaped grooves, thereby playing a role in protecting the cutting edges. When the insulated wire is arranged between the blade and the V-shaped groove, the depth of cutting the insulated wire can be controlled through the positioning device, and the insulated wire is prevented from being damaged due to too deep cutting. The distance between the end of the adjusting bolt 412 and the boss B414 can be adjusted by screwing the adjusting bolt 412, and the spacing between the two "Z" shaped clamping bars 402 can be controlled.

Therefore, when the cutting pliers 4 is used for working, the positioning device is adjusted, one hand holds the wire clamp 1, the other hand cuts the insulation layer of the wire by operating the cutting pliers 4, the cutting pliers 4 are opened (the two hand-held rods B401 are opened), then one end of the wire, which needs to be stripped of the insulation layer part, is positioned between the longitudinal cutter 406 and the wire groove B407, the cutting pliers 4 is clamped, and then the cutting pliers 4 is rotated around the wire simultaneously, so that the longitudinal cutter 406 cuts the surface insulation layer of the end of the wire, which needs to be stripped of the insulation layer part, to form a ring groove. Then, the operation of the cutter pliers 4 is repeated, and the longitudinal cutter 406 of the cutter pliers 4 cuts the surface insulation layer of the other end of the wire from which the insulation layer needs to be removed, thereby forming an annular groove. Then, the part of the wire needing to be stripped is required to be positioned between the cross cutter 404 and the wire groove A405, and then the cross cutter 404 cuts the insulating layer between the two annular grooves along the direction parallel to the axis of the wire to form a strip-shaped groove by clamping the cutting pliers 4. The cutting pliers 4 thus cut 3 slots into the insulation layer to be cut.

The debarking pliers 3 comprises two mutually crossed pliers body rods 302, the pliers body rods 302 are mutually connected in a swinging mode around a rotating shaft B304, the parts, located on one side of the rotating shaft B304, of the two pliers body rods 302 are mutually symmetrical, one side, located on the side of the rotating shaft B304, of one pliers body rod 302 facing to the other pliers body rod 302 is a concave arc, a handheld rod C301 is fixed on one pliers body rod 302 located on the other side of the rotating shaft B304 through a connecting seat B303, the axis of the handheld rod C301 and the symmetrical axis of the symmetrical part of the pliers body rods 302 are on the same straight line, a supporting rod 305 is fixed on the other pliers body rod 302, and one end, far away from the pliers body rods 302, of the supporting rod 305 is rotatably connected with a swinging block 307 through a rotating.

After putting into two pincers body poles 302 with the insulating layer, all the other 4 points to make power downwards, utilize lever principle, two pincers body poles 302 on peeling off 3 top also merge, and pincers body pole 302 presss from both sides the insulating layer tightly this moment, draw and drag or rotatory peeling off pincers 3 can, because anti-skidding line B311 has increased frictional force, the insulating layer is difficult for droing, strips the insulating layer that has cut out the breach.

The blade 2 includes a hand-held rod E201 and a blade 202 fixed to an end of the hand-held rod E201 by a holder D203.

The utility model discloses in the time of using, will adjust the clamp splice 102 of wire clamp 1 earlier and the diameter that is greater than insulated wire between the anchor clamps part 103, then it is located between clamp splice 102 and the anchor clamps part 103 to the wire of waiting to strip the insulating layer to move wire clamp 1, then it presss from both sides tight wire with anchor clamps part 103 to adjust clamp 1 clamp splice 102 again, and the operative employee keeps a handheld pole A101 of holding wire clamp 1, can not shake long in the operation process of stripping the insulating layer with the wire of assurance waiting to strip insulating layer position department. The clamping position of the conductor clamp 1 is located on the insulation stripping side of the conductor strip.

Then, the other hand operates the cutting pliers 4 to cut the insulation layer of the wire, opens the cutting pliers 4, then positions one end of the wire, which needs to be stripped of the insulation layer, between the longitudinal cutter 406 and the wire groove B407, then clamps the cutting pliers 4, and simultaneously rotates the cutting pliers 4 around the wire, so that the longitudinal cutter 406 cuts the surface insulation layer of one end of the wire, which needs to be stripped of the insulation layer, to form a ring-shaped groove. Then, the operation of the cutter pliers 4 is repeated, and the longitudinal cutter 406 of the cutter pliers 4 cuts the surface insulation layer of the other end of the wire from which the insulation layer needs to be removed, thereby forming an annular groove. Then, the part of the wire needing to be stripped is required to be positioned between the cross cutter 404 and the wire groove A405, and then the cross cutter 404 cuts the insulating layer between the two annular grooves along the direction parallel to the axis of the wire to form a strip-shaped groove by clamping the cutting pliers 4.

Then the other hand puts down the cutting pliers 4, takes the peeling pliers 3 and enables the peeling pliers 3 to clamp the insulating layer at the position of the strip-shaped groove, thereby peeling the insulating layer which is positioned between the two annular grooves and is cut with the strip-shaped groove.

Finally, if the conducting wire at the position of the insulating layer is stripped and the insulating layer is remained, the other hand puts down the stripper 3 and uses the scraper knife 2 to completely remove the residual insulating layer on the surface of the conducting wire. After the insulating layer on the surface of the lead is stripped, the lead clamp 1 is separated from the lead.
