Therefore, a T-shaped sliding groove 10 is formed in the position where the upper handle 1 is connected with the limiting block 80 along the length direction of the upper handle 1, the limiting block 80 protrudes towards the upper edge and the lower edge of the end surface of the upper handle 1 to form a clamping block, the clamping block is matched in the sliding groove 10, the limiting block 80 can slide along the groove, and when the limiting block slides, the small end of the adjusting screw 81 can be moved away from the limiting table 20; the limiting block 80 is provided with a fixing member 800, the fixing member 800 limits the sliding distance of the limiting block 80 in the sliding groove 10, and the fixing member 800 may be a butterfly screw, and the small end of the fixing member 800 passes through the limiting block 80 and abuts against the bottom of the sliding groove 10.

When the wire is stripped by using a wire stripper, the position of the limiting block 80 in the chute 10 is adjusted, so that the small end of the screw 81 corresponds to the limiting table 20; when the upper handle 1 and the lower handle 2 are pinched, the screw 81 and the limiting table 20 limit the rotation degree between the upper handle 1 and the lower handle 2, so that the opening blade 4 and the cutting blade 6 can only cut the insulating layer of the electric wire and are not easy to damage the conducting wire in the insulating layer; when a wire is required to be cut, the position of the limiting block 80 in the sliding groove 10 is adjusted, and the small end of the screw 81 is moved away from the limiting table 20, so that when the upper handle 1 and the lower handle 2 are pinched, the screw 81 and the limiting table 20 cannot be matched, the rotation degree between the upper handle 1 and the lower handle 2 cannot be limited, and the cutting blade 6 can extend into the abdicating groove 70 to cut off the wire; the fixing member 800 limits the sliding distance of the limiting block 80 in the sliding groove 10, and when different working states of the wire stripper need to be switched, after the position of the limiting block 80 in the sliding groove 10 is adjusted, the fixing member 800 is used for limiting the position of the limiting block 80, so that the wire stripper is not easy to slide and the use is not affected.

Because of reasons such as electric load, different circuits or different positions of circuits need to use different electric wires, and the thickness of electric wire, insulating layer etc. are different, and some electric wires are thicker or the insulating layer is harder to people just need to use great power to pinch upper handle 1 and lower handle 2 when the operation, waste time and energy.

Therefore, referring to fig. 1 and 2, the force application ends of the upper handle 1 and the lower handle 2 are extended; the extension structure is described below with the handle 2 as an example; an extension part 21 is arranged, the force application end of the lower handle 2 is arranged into a cylindrical structure with an open end surface, and the end surface of the open end extends inwards along the radial direction to form an annular baffle 22; a part of the extension part 21 is slidably fitted in the force application end of the lower handle 2, and the end of the part of the extension part 21 in the lower handle 2 is thicker and is restricted by the blocking piece 22 and cannot be separated; the insulating sleeve 9 is sleeved outside the force application end of the lower handle 2, the bottom of the insulating sleeve 9 is fixedly connected with one end, located outside the lower handle 2, of the extension portion 21, and a circle of soft cushion 91 is arranged at the connection position.

When the wire is easy to be stripped and people do not need to use too much force, and the extension part 21 is accommodated in the lower handle 2, the soft cushion 91 is squeezed between the baffle piece 22 and the side wall of the extension part 21, so that the baffle piece 22 and the side wall are not easy to be separated; when the electric wire is not easy to be stripped, the insulating sleeve 9 is pulled outwards, the insulating sleeve 9 drives the extension part 21 to slide outwards towards the lower handle 2, so that the length of the lower handle 2 is extended, and people can strip or cut the electric wire more easily with the help of larger torque when applying force.

The fixed connection between the bottom of the insulating sleeve 9 and the end of the extension 21 outside the lower handle 2 may be by gluing or screwing, and in this embodiment, by countersunk head screws.

The embodiment of this embodiment is the utility model discloses preferred embodiment is not according to this restriction the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
