[0024] Embodiment 1

[0025] As Figures 1-3 shown, it relates to a cable stripping knife, which includes a U-shaped seat 1. Clamping assemblies 2 are provided on both sides of the U-shaped seat 1. A gantry 3 is fixed on the top of the U-shaped seat 1. Two support assemblies 4 are jointly connected between the two sides of the gantry 3 and the upper surface of the U-shaped seat 1. A second screw 5 penetrates through and is threadedly rotatably connected to the top of the gantry 3. The bottom end of the second screw 5 is rotatably connected to a tool holder 6 through a bearing. A tool groove 61 is formed at the bottom of the tool holder 6, and a blade 7 is installed inside the tool groove 61. An installation assembly 8 for fixing the blade 7 is provided on the side of the tool holder 6. Guide assemblies 9 are connected to both sides of the tool holder 6.

[0026] The clamping assembly 2 includes a first screw 21 that penetrates through the side wall of the U-shaped seat 1 and is threadedly connected to the side wall of the U-shaped seat 1. One end of the first screw 21 located inside the U-shaped seat 1 is rotatably connected to a pressure plate 22 through a bearing.

[0027] When using this stripping knife, the U-shaped seat 1 can be clamped at a certain position, and then the pressure plate 22 is driven to move by rotating the first screw 21, and clamping is performed by using the pressure plate 22 so that this stripping knife is fixed.

[0028] The support assembly 4 includes a diagonal rod 41 fixedly connected to the upper surface of the U-shaped seat 1 and the inner wall of the gantry 3. A roller 42 is rotatably connected to the surface of the diagonal rod 41.

[0029] When the cable moves above the two support assemblies 4, the roller 42 can reduce the friction force and make it smoother to pull the cable.

[0030] The guiding component 9 includes cross bars 91 fixed to both sides of the tool holder 6. The other end of the cross bar 91 is fixedly connected with a sliding sleeve 92. The sliding sleeve 92 is sleeved on the surface of the gantry 3 and is slidably connected with the gantry 3.

[0031] By rotating the second screw rod 5, the tool holder 6 can be driven to move up and down. The guiding component 9 is provided to make the up and down movement of the tool holder 6 more stable.

[0032] The installation component 8 includes a locking bolt 81 passing through the side wall of the tool holder 6 and threadedly connected with the side wall of the tool holder 6. And one end of the locking bolt 81 located in the tool groove 61 is in contact with the surface of the blade 7.

[0033] In this embodiment, when installing the blade 7, after inserting the blade 7 into the tool groove 61, tighten the locking bolt 81 to squeeze and fix the blade 7.

[0034] Embodiment Two

[0035] As Figures 4-6 shown, as an alternative solution to the installation component 8 in Embodiment One, a through hole 62 is provided on the side wall of the tool holder 6. A clamping hole 71 is provided at one end of the blade 7 located in the tool groove 61. The installation component 8 includes a clamping rod 82 passing through the through hole 62 and slidably connected with the through hole 62. One end of the clamping rod 82 located outside the tool holder 6 is fixedly connected with an end cap 83. A tension spring 84 is fixedly connected between the end cap 83 and the outer side wall of the tool holder 6. One end of the clamping rod 82 located in the tool groove 61 is snapped into the inside of the clamping hole 71.

[0036] In this embodiment, when installing the blade 7, first pull the clamping rod 82 out of the tool groove 61 through the end cap 83. Then insert the top of the blade 7 into the tool groove 61. Subsequently, release the end cap 83. Under the pulling action of the tension spring 84, the clamping rod 82 is snapped into the clamping hole 71 at the top of the blade 7 to realize the fixed installation of the blade 7.

[0037] Working principle: First, fix the U-shaped seat 1 at a specified position through the clamping component 2 to realize the fixed installation of the wire stripping knife. Then, according to the diameter of the cable to be stripped, rotate the second screw rod 5 to drive the tool holder 6 and the blade 7 to rise or fall, ensuring that when the cable passes through the surfaces of the two support components 4, the blade 7 can just cut open the cable skin. After the adjustment is completed, pass the cable through the surface of the support component 4 and between the blades 7, and pull the cable to move, and use the blade 7 to cut open the cable skin. The wire stripping knife is fixed and installed for use, and only needs to pull the cable alone to realize the wire stripping operation, which is safer and more reliable.
