[0030] See alsoFigures 1-4 , an embodiment provided by the present utility model:

[0031] A cable stripping pliers, which includes:

[0032] The first pliers rod 1, the first pliers rod 1 is rotatably connected to the second pliers rod 3 through a rotating shaft 2. A limiting threaded rod 4 is vertically threadedly installed at the top of the first pliers rod 1. A fixed clip 5 is installed at the end of the top of the first pliers rod 1. The locking bolts 6 are symmetrically distributed about the center of the fixed clip 5. The locking bolts 6 are threadedly connected to the fixed clip 5. The inner wall of the hole opened at the end of the locking bolt 6 is in close contact with the end of the movable clip 7. The above structural design enables the fixed clip 5 and the movable clip 7 to stably squeeze and position the longitudinal blade 8;

[0033] The fixed clip 5, a locking bolt 6 is installed at the end of the fixed clip 5. The locking bolt 6 passes through the hole opened at the end of the movable clip 7. A longitudinal blade 8 is arranged between the fixed clip 5 and the movable clip 7. A positioning strip 9 is arranged on the side of the longitudinal blade 8. The positioning strip 9 is in close contact with the inner wall of the positioning groove 10. The above structural design ensures that the longitudinal blade 8 can be smoothly adjusted vertically and remains stable without skewing. The positioning strip 9 and the positioning groove 10 are both symmetrically distributed about the center of the longitudinal blade 8. The positioning strip 9 is in close contact with the inner wall of the positioning groove 10. The positioning grooves 10 are symmetrically opened on the opposite surfaces of the fixed clip 5 and the movable clip 7. The above structural design enables the longitudinal blade 8 to stably slide linearly along the positioning groove 10 with the positioning strip 9 when being adjusted, and the symmetric positioning strip 9 and positioning groove 10 can prevent the longitudinal blade 8 from skewing during adjustment;

[0034] The second pliers rod 3, a first positioning plate 11 is fixed at the end of the bottom of the second pliers rod 3. The first positioning plate 11 is arranged on one side of the rotating shaft 2. A second positioning plate 12 is fixedly installed at the top of the bottom of the first pliers rod 1 on the other side of the rotating shaft 2. An adjusting sleeve 14 is rotatably installed on the side surface of the second pliers rod 3 above the second positioning plate 12. An adjusting threaded rod 15 is installed through the center of the adjusting sleeve 14. The bottom end of the adjusting threaded rod 15 is connected and fixed to the top end of the transverse blade 16.

[0035] In one embodiment, small blades 13 are fixed on the inner side surfaces of the first positioning plate 11 and the second positioning plate 12. The center of the first positioning plate 11 and the center of the longitudinal blade 8 are in the same vertical plane. The center of the second positioning plate 12 and the center of the transverse blade 16 are in the same vertical plane. The above structural design can play a certain positioning effect on the cable from the bottom.

[0036] In one preferred embodiment, the small blades 13 are symmetrically distributed on both sides of the inner walls of the first positioning plate 11 and the second positioning plate 12. The length of the small blades 13 is equal to the length of the first positioning plate 11 and the second positioning plate 12. The above structural design ensures the positioning effect of the small blades 13 on the cable.

[0037] In one embodiment, the length of the second positioning plate 12 is greater than the thickness of the first clamping rod 1, and the distance between the top ends on both sides of the second positioning plate 12 is not less than the length of the transverse blade 16. The above structural design further ensures the stability when the cable is in contact with the second positioning plate 12.

[0038] In one preferred embodiment, the front view shape of the adjusting sleeve 14 is "T"-shaped. The adjusting sleeve 14 is threadedly connected to the adjusting threaded rod 15, and both the adjusting sleeve 14 and the adjusting threaded rod 15 are symmetrically distributed about the center of the transverse blade 16. The above structural design makes the adjusting sleeve 14 easy to operate. The symmetrically distributed adjusting sleeves 14 can utilize the threaded connection relationship to conveniently drive the adjusting threaded rod 15 to drive the transverse blade 16 to linearly move to adjust the working position when rotating.

[0039] The working principle of the present utility model is as follows: When longitudinal peeling is required, first adjust the working height of the longitudinal blade 8 according to the diameter of the cable. Slightly loosen the symmetrically distributed locking bolts 6, and then push the longitudinal blade 8 with the positioning strip 9 to linearly slide and adjust along the positioning groove 10 until the position of the longitudinal blade 8 is appropriate. Rotate the locking bolt 6 to reset and squeeze the movable clamping piece 7. The movable clamping piece 7 squeezes the longitudinal blade 8 to fit and fix with the fixed clamping piece 5. Rotate the limit threaded rod 4 to move up and down to adjust the shearing amplitude. Place the head of the cable to be peeled in the first positioning plate 11, and hold the Figure 3 right ends of the first clamping rod 1 and the second clamping rod 3 in the figure, and close the left ends to perform longitudinal shearing and peeling. Figure 1 In the figure, the right ends of the first clamping rod 1 and the second clamping rod 3 are held, and the left ends are closed to perform longitudinal shearing and peeling.

[0040] When transverse peeling is required, first adjust the working height of the transverse blade 16 according to the diameter of the cable. At the same time, rotate the symmetrically distributed adjusting sleeves 14 in the same direction. The adjusting sleeves 14 drive the adjusting threaded rods 15 to drive the transverse blade 16 to linearly move by using the threaded connection relationship until the working position of the transverse blade 16 is appropriate. Stop rotating the adjusting sleeves 14, and use the thread self-locking to fix the positions of the adjusting threaded rods 15 and the transverse blade 16. Place the cable to be peeled in the second positioning plate 12, and hold the Figure 1 right ends of the first clamping rod 1 and the second clamping rod 3 in the figure, and make the second clamping rod 3 drive the transverse blade 16 to perform transverse cutting and peeling on the insulating skin of the cable.
