Detailed Description

The utility model discloses a cable sheath stripping tool, including pincers 1, even handle 2 and two sets of locking pieces 3, pincers 1 include first tong arm 11 and second tong arm 12 of mutual articulated, one end of first tong arm 11 is first cutting part 111, another end is first handle portion 112; the second end of the second forceps arm 12 corresponding to the first blade 111 is a second end, and the second handle 122 corresponding to the first handle 112 is a second handle; the connecting handle 2 is detachably connected with the first handle part 112 and the second handle part 122, and two end parts of the connecting handle 2 respectively extend out of two sides of the first handle part 112 and the second handle part 122 to form holding parts; one of the two locking pieces 3 is detachably connected with the connecting handle 2 and the first handle part 112 respectively; the other group is detachably connected with the connecting handle 2 and the second handle part 122, so that the relative positions of the connecting handle 2, the first handle part 112 and the second handle part 122 are respectively fixed, and the connecting handle 2 is prevented from displacing.

Further, in order to realize the detachable connection of the connecting handle 2 with the first handle part 112 and the second handle part 122, a first connecting hole penetrating through the left and right sides of the first handle part 112 and matching with the connecting handle 2 in size is formed at a position of the first handle part 112 far away from the first blade part 111, a second connecting hole aligning with the first connecting hole is formed at a position corresponding to the second handle part 122, the connecting handle 2 passes through the two connecting holes, and then the connecting handle 2 and the two handle parts are fixed through the detachable connection of the locking piece 3 with the connecting handle 2 and the two handle parts;

due to the design, the clamp 1 is formed by hinging the first clamp arm 11 and the second clamp arm 12, so that the relative position of the handle is fixed, and meanwhile, the relative position of the blade part is also fixed, after the cable sheath is clamped by the first blade part 111 and the second blade part 121, the connecting handle 2 passes through the first connecting hole and the second connecting hole to fix the first handle part 112 and the second handle part 122, and the blade part is also fixed correspondingly, so that in the subsequent operation, the clamp 1 is not required to be forced by hands of workers to clamp the sheath;

meanwhile, two end parts of the connecting handle 2 respectively extend out of two sides of the first handle part 112 and the second handle part 122 to form holding parts, and a worker only needs to hold the holding parts and apply force to the arms to drive the clamp 1 to move circumferentially, so that the sheath of the cable can be stripped; the traditional clamp 1 is prevented from being stripped by the force of the wrists due to the force of the arms, on one hand, the wrists of workers are protected from being damaged, on the other hand, the arm force is larger than the wrist force, and the efficiency of stripping the cable sheath can be improved due to the fact that the arms are used for exerting force.

Furthermore, when the sheath is stripped, any edge part of the clamp 1 firstly pokes between the sheath and the wrapping layer, the sheath and the wrapping layer are separated, and then the shearing and stripping operation is carried out, in the process, factors such as the length and the width of the edge part influence the stripping effect, if the length of the edge part is too short, although the operation of stripping the sheath can be carried out, the sheath is stripped and then wraps the outer surface of the edge part, if the length of the edge part is too short, the edge part can be completely wrapped after a small section of the sheath is stripped, and further the operation of stripping the sheath is needed to be carried out after the stripped sheath is processed, so that the sub-operation has low stripping efficiency, and the edge part is frequently processed, so that the clamp 1 needs to poke between the sheath and the wrapping layer frequently when the subsequent stripping operation is carried out on, and because the wrapping layer is generally made of rubber, the clamp 1 is easy to damage under continuous friction; if the length of the blade part is too long, the middle section of the blade part is easy to crack due to the action of shearing stress and the like, and if the length of the blade part is too long and the length of the handle part is not changed, the force required for stripping is increased; therefore, the length of the blade part needs to be adjusted reasonably, the length of the blade part is adjusted to be 40-45mm, the width of the blade part is adjusted to be narrow, after the adjustment, when the sheath is stripped, the blade part can be wound on the longer sheath, the times of processing the blade part are reduced, the times of stabbing the clamp 1 into the sheath and wrapping the sheath are reduced, the width of the blade part is narrowed, the pressure between the blade part and the wrapping layer can be reduced, and the internal structure of the cable can be protected while the working efficiency is improved.

Furthermore, in order to prevent the situation that a worker slips hands when using the cable sheath stripping tool disclosed by the disclosure to strip a cable sheath, an anti-slip sleeve is sleeved at the position of the holding part of the connecting handle 2, the anti-slip sleeve adopts a common rubber sleeve, and granular protrusions are formed on the outer surface of the rubber sleeve, so that the anti-slip function is achieved, and the situation that the worker slips hands and further injures hands when using the cable sheath stripping tool to strip the cable sheath and forcibly rotating the stripping tool is avoided;

in addition, the anti-skidding sleeve and the connecting handle 2 are detachably connected, so that the anti-skidding sleeve cannot obstruct the installation and the disassembly of the connecting handle 2.

The connection between the connecting handle 2 and the pliers 1 of the cable sheath stripping tool disclosed in the present disclosure is implemented as follows, in the present disclosure, the installation and operation processes are described in embodiment 1, and the installation and operation processes in embodiment 2 are similar to those in embodiment 1, and therefore the processes are not described again.
