Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a stripping tool for cable construction, including a fixing structure and a cutting structure, the fixing structure including a lower clamping plate 2 and an upper clamping plate 1, one end of the lower clamping plate 2 and the upper clamping plate 1 are in a state of active connection, and both sides of the other end of the lower clamping plate 2 are fixedly connected with elastic clips 3. When the fixing structure is in a closed state, the upper clamping plate 1 and the lower clamping plate 2 are clamped together by the elastic clips 3, and the inner side of the elastic clip 3 away from the end of the lower clamping plate 2 is inclined outwardly, and the material of the elastic clip 3 can be metal copper. The lower clamping plate 2 and the upper clamping plate 1 are fixed with handles at one end close to the elastic clip 3. Through the setting of the fixing structure, the user can bend the two handles outward to separate the lower clamping plate 2 and the upper clamping plate 1, and the user pushes the two handles inward, so that the lower clamping plate 2 and the upper clamping plate 1 can be quickly clamped.

[0024] A cable placement hole is provided in the middle of the fixed structure. When the stripping tool is in use, the cable to be stripped is placed in the cable placement hole. When the upper clamping plate 1 and the lower clamping plate 2 are clamped, the cable can be clamped by the upper clamping plate 1 and the lower clamping plate 2 to fix the position of the cable.

[0025] The inner cavity of the cable placement hole is connected with an inner lining ring 4 through a bolt 5. The inner lining ring 4 is a semicircular structure. The middle of the outer wall of the inner lining ring 4 is provided with a bolt hole adapted to the bolt 5. The middle of the top and the middle of the bottom of the cable placement hole are both threadedly connected with bolts 5. Through the setting of the inner lining ring 4, when the inner lining ring 4 is fixed to the lower clamping plate 2 or the upper clamping plate 1, the cable adapted to the inner diameter of the inner lining ring 4 can be clamped by the fixed structure, and the inner lining ring 4 can be quickly disassembled and assembled, so that when the stripping tool is actually used, the user can replace the inner lining ring 4 with different inner diameters, so that the stripping tool can adapt to cables of various sizes, thereby improving the adaptability of the stripping tool. The inner diameter of the inner lining ring 4 is fixed with an interference ring, and the material of the interference ring can be rubber. Through the setting of the interference ring, when the lower clamping plate 2 and the upper clamping plate 1 are clamped, the fixed structure can be tightly fixed to the cable.

[0026] Both sides of the fixed structure are provided with a cable clamping structure, and the cable clamping structure includes a ball screw 6 movably connected to the fixed structure, and the middle part of the bottom of the lower clamping plate 2 and the middle part of the top of the upper clamping plate 1 are movably connected with a ball screw 6, and the outer ring of the ball screw 6 is threadedly connected with a ball nut 1, and the ball nut 1 is fixedly connected to the translation rod 8. A threaded hole is provided in the middle of the other end of the translation rod 8, and a lifting rod 10 is movably connected in the inner cavity of the threaded hole. The outer ring of the bottom end of the lifting rod 10 is fixedly connected with a threaded tube, and the threaded tube is adapted to the threaded hole. The bottom of the lifting rod 10 is fixedly connected with an extrusion block 1 4. The extrusion block 14 is fixedly connected to the translation rod 8 by the spring 9. It can be known from the above description of the cable clamping structure that when the ball screw 6 rotates, the rotation of the ball screw 6 can make the ball nut 1 threadedly connected thereto move in the direction of the ball screw 6. When the ball nut 1 moves, it can drive the translation rod 8 fixedly connected thereto to move. When the translation rod 8 moves, it can drive the extrusion block 14 to move. Under the action of external force, the lifting rod 10 can drive the extrusion block 14 to move, thereby releasing the restriction on the lifting rod 10. The rebound force of the spring 9 can push the extrusion block 14 to move in the reverse direction.

[0027] A positioning ring 19 is fixedly connected to the outer side of one end of the cable placement hole, and the cutting structure is movably connected to the positioning ring 19. The cutting structure includes a rotating handle, and the rotating handle includes a semicircular ring 17 and a semicircular ring 2 18. The semicircular ring 17 is clamped with the semicircular ring 2 18. The end of the rotating handle that is adapted to the positioning ring 19 is symmetrically provided with a cutting groove 22 and a through groove 17 adapted to the extrusion block 14.

[0028] A clamping block is fixed on the inner side of one end of the semicircular ring 1 7 away from the cutting groove 22, and a clamping groove is provided on the inner side of one end of the semicircular ring 2 18 away from the cutting groove 22. The clamping block is adapted to the clamping groove, and the semicircular ring 1 7 and the semicircular ring 2 18 are clamped together through the clamping block and the clamping groove.

[0029] A cutting knife 21 is movably connected in the inner cavity of the cutting groove 22, and one end of the cutting knife 21 away from the indicating rod 20 is a diamond structure. The cutting knife 21 is connected to the rotating handle through a ball screw 15. The outer side of the semicircular ring 17 and the outer side of the semicircular ring 18 are both movably connected with a ball screw 15. The outer ring of the ball screw 15 is threadedly connected with a ball nut 2, and the outer ring of the ball nut 2 is fixedly connected with the indicating rod 20. The outer side of the rotating handle is fixedly connected with a scale plate 16. One end of the indicating rod 20 is fixedly connected to the cutting knife 21. The other end is in contact with the scale plate 16. Through the setting of the ball screw 2 15, the rotation of the ball screw 2 15 can make the ball nut 2 threadedly connected thereto move in the direction of the ball screw 2 15. When the ball nut 2 moves, it can drive the indicator rod 20 to move. When the indicator rod 20 moves, it can drive the cutting knife 21 fixedly connected thereto to move. The user can accurately control the moving distance of the cutting knife 21 through the scale plate 16, so that when the skinning tool is used, the skinning depth can be adjusted according to the needs, thereby improving the adaptability of the skinning tool. The outer diameter of the cutting knife 21 close to the end of the indicator rod 20 is larger than the outer diameter of the other end. Through the setting of the cutting knife 21, the cutting knife 21 can perform transverse circular cutting and longitudinal cutting.

[0030] The end of the rotating handle away from the cutting groove is connected to the inner lining ring 13 by bolt 2. The inner lining ring 13 is a semicircular structure. The ends of the semicircular ring 17 and the semicircular ring 18 away from the cutting groove 22 are both fixed with a fixed block 11. One end of the inner lining ring 13 is fixed with a fixed block 12. The fixed block 11 and the fixed block 12 are connected by bolt 2. Through the setting of the inner lining ring 13, the inner diameter of the rotating handle can be changed, so that the rotating handle can adapt to cables of various sizes. When the rotating handle is sleeved outside the cable, the inner wall of the inner lining ring 13 contacts the cable, and under the action of external force, the rotating handle can rotate and move longitudinally, and when the rotating handle contacts the upper clamping plate 1, the cutting knife 21 is aligned with the cutting part of the cable.

[0031] From the above description of the cutting structure, it can be seen that the positioning ring 19 can position the cutting structure, making it convenient for the user to drive the cutting structure to perform transverse circular cutting on the cable, and the user can drive the cutting structure to move longitudinally. When the cutting structure moves longitudinally, it can cut the cable longitudinally, thereby improving the cable cutting efficiency.

[0032] In summary: when the stripping tool for cable construction is used, the user selects the inner lining ring 14 and the inner lining ring 2 13 that are adapted to the outer diameter of the cable according to the needs, and uses the bolt 15 to fix the inner lining ring 14 in the cable placement hole, and uses the bolt 2 to fix the inner lining ring 2 13 and the rotating handle together, and the stripping tool is adapted to the cable. The user separates the upper clamping plate 1 and the lower clamping plate 2, puts the cable to be cut in the inner cavity of the inner lining ring 14 connected to the lower clamping plate 2, and adjusts the position of the cable until the end of the inner lining ring 14 close to the positioning ring 19 is aligned with the cutting part of the cable, and the user flips the upper clamping plate 1, and uses the spring clamp 3 to fix the upper clamping plate 1 and the lower clamping plate 2 together, at which time the fixing structure is fixed to the cable. The user respectively makes the inner wall of the semicircular ring 17 away from one end of the inner liner ring 2 13 and the inner wall of the semicircular ring 2 18 away from one end of the inner liner ring 2 13 contact with the outer diameter of the positioning ring 19, and makes the semicircular ring 17 and the semicircular ring 2 18 clamped, the rotating handle is sleeved on the outside of the cable, the user moves the rotating handle until the rotating handle is tightly fitted with the upper clamping plate 1, at this time, the cutting knife 21 is aligned with the cutting part of the cable, the user rotates the ball screw 2 15 according to the demand, the rotation of the ball screw 2 15 changes the cutting depth of the cutting knife 21, the user adjusts the cutting depth of the cutting knife 21 according to the scale plate 16, and after the cutting depth of the cutting knife 21 meets the demand The user rotates the rotating handle, and the rotating handle drives the cutting knife 21 to rotate. The cutting knife 21 can perform transverse ring cutting on the cable. After the cable is transversely ring cut, the user adjusts the position of the rotating handle so that the through groove 17 is aligned with the extrusion block 14. The user rotates the lifting rod 10 to release the restriction on the lifting rod 10. Under the action of the rebound force of the spring 9, the rebound force of the spring 9 pushes the extrusion block 14 to move until the extrusion block 14 is tightly fitted with the cable surface. The two extrusion blocks 14 are used in coordination to fix the cable skin. The user pulls the rotating handle, and the rotating handle drives the cutting knife 21 to move, thereby achieving longitudinal cutting of the cable skin, which is convenient for stripping the cable skin.
