[0032] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0033] Please see Figures 1 to 11 As shown, a cable stripper includes: a housing, an inner sleeve, a blade 1, and a locking mechanism; the housing includes an upper half-shell 21 and a lower half-shell 22, one side of the upper half-shell 21 and one side of the lower half-shell 22 are hinged together, and the other side of the upper half-shell 21 and the other side of the lower half-shell 22 are connected by the locking mechanism; the inner sleeve includes an upper inner sleeve 31 and a lower inner sleeve 32, the upper inner sleeve 31 is detachably connected to the upper half-shell 21, and the lower inner sleeve 32 is detachably connected to the lower half-shell 22. When the upper half-shell 21 and the lower half-shell 22 are connected by the locking mechanism, the upper inner sleeve... The upper shell 21 and the lower inner sleeve 32 are joined to form a cylindrical through hole for placing the cable; a support frame 4 is provided on the side of the upper shell 21, and mounting holes 5 are provided on the upper shell 21 and the upper inner sleeve 31 respectively. The lower end of the support frame 4 passes through the upper shell 21 and is fixed to the inner wall of the mounting hole 5 of the upper inner sleeve 31. The blade 1 is detachably connected to the support frame 4 and the blade of the blade 1 extends into the cylindrical through hole; a handle 6 is connected to the side of the upper shell 21, and a horizontal surface is provided on the side wall of the lower shell 22. A sliding mechanism for sliding the lower shell 22 is provided on the horizontal surface.

[0034] The outer shell includes an upper shell 21 and a lower shell 22. The upper shell 21 and lower shell 22 are respectively provided with spaces for installing the upper inner sleeve 31 and the lower inner sleeve 32, facilitating their installation. Specifically, bolts can be used for installation. The upper inner sleeve 31 is fixed to the upper shell 21, and the lower inner sleeve 32 is fixed to the lower shell 22. When the locking mechanism is not used to fix the upper shell 21 and lower shell 22, the upper shell 21 can drive the upper inner sleeve 31 to rotate along the hinge axis between the upper shell 21 and lower shell 22. The device features a large opening for easy cable insertion and removal. A locking mechanism provides stable and reliable fixing force when the device is in operation, preventing slippage or displacement due to external forces or vibration. Both the upper inner sleeve 31 and lower inner sleeve 32 have semi-circular cross-sections. The inner sleeves limit the cable's position when the locking mechanism locks the upper half-shell 21 and lower half-shell 22, facilitating cable stripping by the blade 1. A handle 6 is provided for easy handling. A sliding mechanism allows for easy dragging on the ground. This device reduces safety hazards during cable stripping, avoids direct close contact between the operator and the blade 1, and increases safety. Simultaneously, the outer shell, inner sleeves, and locking mechanism secure the cable, facilitating accurate cable cutting and improving cutting efficiency.

[0035] Furthermore, such as Figures 2 to 4and Figure 6 As shown, both the upper shell 21 and the lower shell 22 have limiting guide grooves 23 on their inner walls. The upper inner sleeve 31 and the lower inner sleeve 32 have several positioning holes corresponding to the limiting guide grooves 23, and also have positioning rods 33. One end of the positioning rod 33 is inlaid with a first ball bearing 331, and the surface of the positioning rod 33 has external threads. The inner wall of the positioning hole has internal threads that mate with the external threads. When the positioning rod 33 is threadedly connected to the positioning hole, the other end of the positioning rod 33 extends into the limiting guide groove 23. When the positioning rod 33 is threadedly connected to the positioning hole, only a portion of the first ball bearing 331 protrudes from the positioning hole and contacts the cable sheath during use. The first ball bearing 331 can roll on the cable sheath, resulting in a low coefficient of rolling friction. The limiting guide groove 23 ensures the accuracy of the inner sleeve and outer shell installation when the positioning rod 33 is installed, as the positioning rod 33 extends into the limiting guide groove 23.

[0036] Furthermore, such as Figures 1 to 5 As shown, the locking mechanism includes a fixed shaft 71, a screw 72, and a wing nut 73. Both the upper shell 21 and the lower shell 22 have U-shaped portions connected to their sides. The fixed shaft 71 is fixedly connected to the U-shaped portion of the lower shell 22. One end of the screw 72 is rotatably connected to the fixed shaft 71, and the shaft is parallel to the hinge axis of the upper shell 21 and the lower shell 22. The wing nut 73 is threaded onto the screw 72. The screw 72 can pass through the middle of the U-shaped portion of the upper shell 21 and be fixed by the wing nut 73. The openings of the U-shaped portions of the upper shell 21 and the lower shell 22 are both set outwards to facilitate the rotation of the screw 72 for locking. The size of the wing nut 73 is larger than the size of the opening of the U-shaped portion. When locking, the upper shell 21 is rotated to align with the lower shell 22, and the screw 72 is rotated so that one end of the screw 72 is located inside the U-shaped portion of the upper shell 21. When the wing nut 73 is rotated until it contacts the U-shaped portion of the upper shell 21, it continues to rotate, so that the upper shell 21 and the lower shell 22 gradually approach each other and reach the required locking force.

[0037] Furthermore, such as Figure 3 and Figures 8 to 10As shown, the support frame 4 has an inverted U-shaped cross-section. Multiple horizontal through holes 41 are provided on the sidewalls of the support frame 4 along its height. These horizontal through holes 41 are connected to a vertical hole on their sides. Bolts pass through these horizontal through holes 41. The blade 1 is connected to a mounting plate located inside the support frame 4 and fixed within it by bolts. The support frame 4 is used to fix the blade 1. The blade 1 is connected to the mounting plate, which is fixed by bolts. Specifically, during fixing, the bolt thread passes through one side of the horizontal through hole 41 of the support frame 4 and then through the mounting plate. The mounting plate has a hole, and the bolt thread exits through the other side of the support frame 4's horizontal through hole 41, and is tightened by a nut that mates with the bolt. The multiple horizontal through holes 41 allow adjustment of the mounting plate's position, thereby adjusting the depth to which the blade 1 extends into the cylindrical through hole, allowing adjustment based on the cable sheath thickness. When adjusting the mounting position, the bolt first moves from one horizontal through hole 41 into the vertical hole and then into another horizontal through hole 41. Furthermore, the blade 1 can be a longitudinal cutting blade or a transverse cutting blade, and the structure of the longitudinal cutting blade is as follows: Figures 8 to 10 As shown, the structure is disc-shaped, with a central shaft passing through the center of the longitudinal cutting blade. The central shaft is rotatably connected to the mounting plate, so that during operation, the central shaft is perpendicular to the hinge axis of the upper half-shell 21 and the lower half-shell 22; the structure of the transverse cutting blade is as follows. Figure 11 As shown, it includes an arc-shaped cutter and a connecting handle. The connecting handle is fixed to a connecting plate. During operation, the arc-shaped cutter strips the cable sheath by conforming to the circumference of the cable.

[0038] Furthermore, such as Figure 1 , Figure 3 and Figure 7 As shown, the sliding mechanism includes a second ball bearing 81 and a connecting rod. The lower end of the connecting rod has a downward-opening mounting groove 831, in which the second ball bearing 81 is embedded. The upper end of the connecting rod is threaded to the horizontal surface. A connecting hole is provided on the horizontal surface, with an internal thread inside. An external thread that mates with this internal thread is provided on the surface of the connecting rod. The threaded connection between the connecting rod and the horizontal surface allows the second ball bearing 81 to contact the ground, resulting in low rolling friction and facilitating the dragging of the device.

[0039] Furthermore, such as Figure 7As shown, the connecting rod includes a connecting rod body 82 and a connecting block 83. The connecting block 83 has a through hole, and the lower end of the connecting rod body 82 is fixed in the through hole to form the mounting groove 831. An elastic groove 821 is provided at the bottom of the connecting rod body 82, and a slider is slidably connected in the elastic groove 821. A spring 91 is connected between one side of the slider and the bottom of the elastic groove 821, and a stop block 92 is fixedly connected to the other side. The stop block 92 extends out of the elastic groove 821 and abuts against the second ball bearing 81. With the spring 91, when compressed, the second ball bearing 81 presses upward against the stop block 92, and the movement of the stop block 92 causes the spring 91 to contract, allowing it to adapt to movement on uneven ground. Even when the stop block 92 is completely located in the elastic groove 821, part of the second ball bearing 81 still extends out of the mounting groove 831 and remains in contact with the ground, ensuring smooth overall sliding.

[0040] Furthermore, such as Figure 3 and Figure 4 As shown, in order to improve reliability, two limiting guide grooves 23 are provided in the upper shell 21, and three limiting guide grooves 23 are provided in the lower shell 22.

[0041] Before use, install the appropriate blade 1 according to the requirements. When making transverse cuts, install the transverse cutting blade, determine the length of the cable, put the cable into the lower inner sleeve 32, rotate the upper half shell 21, and connect and fix the upper half shell 21 and the lower half shell 22 by rotating the wing nut 73, so that the transverse cutting blades at both ends are pressed into the cable sheath by about 1-2mm. Then rotate the device, the first ball 331 contacts the cable sheath and rolls with the rotation of the device to reduce friction and perform a circumferential cut on the cable. When making longitudinal cuts, install the longitudinal cutting blade, and then connect and fix the upper half shell 21 and the lower half shell 22 by the wing nut 73, so that the transverse cutting blades at both ends are pressed into the cable sheath by about 1-2mm. Then drag the device along the length of the cable, the second ball 81 at the bottom can roll and rub against the ground, the first ball 331 contacts the cable sheath and rolls with the drag of the device to reduce friction and perform a longitudinal sliding cut on the cable.
