[0029] Under the manual operation and rotation of the lead screw 2, the traction block 7 connected via the screw hole 703 is driven to move along the straightening rod 1 between the front end fixing plate 8 and the rear end fixing plate 3. At the same time, the L-shaped block 701 connected to the top of the traction block 7 and the straightening wheel 4 connected via the first screw 702 and the L-shaped rod 402 move together, and combined with the cable clamping mechanism to fix the corresponding part of the cable, it is helpful to straighten the end part of the cable and solve the problem that the cable is rough and hard and inconvenient to straighten.

[0036] The specific steps are as follows:

[0037] Step 1: According to the length of the cable end to be processed, the two rollers 102 located at the front fixing plate 8 are brought into contact with the portion of the cable at the corresponding length, and the two upper and lower limiting wheels 11 are brought into close contact with the corresponding surface of the cable under the action of the U-shaped member 10 moving inwards driven by the second screw 9 to rotate, so as to clamp and fix the whole structure on the cable;

[0038] Step 2: The first screw 702 is rotated to drive the straightening wheel 4 connected via the L-shaped rod 402 to approach the corresponding part of the cable until the balls 401 distributed in an annular manner in the middle of the straightening wheel 4 roll in contact with the surface of the cable, and at the same time, one side of the cable at this location contacts the corresponding parts of the two straightening rods 1 distributed above and below;

[0039] Step 3: Rotate the lead screw 2 to drive the traction block 7 through the screw hole 1 703 to move along the straightening rod 1 toward the rear end fixing plate 3 under the action of the sliding connection between the connecting protrusion 3 704 and the strip slide groove 103 located on the straightening rod 1, and at the same time drive the L-shaped block 701, the first screw 702 and the straightening wheel 4 connected to the traction block 7 to move, so as to realize the straightening of the cable end part, which is convenient for subsequent end stripping and other processing;

[0040] Step 4: Since the display 13 is provided with a controller and multiple control buttons, the following specific cable end stripping operation is performed: after the cable end portion is straightened, the lead screw 2 is rotated again to move the portion connected to the traction block 7 back, and the displacement size data displayed by the turned-on displacement sensor 6 and the display 13 are combined to accurately determine the starting point of the cable stripping;

[0041] Step 5: According to the known thickness of each insulating layer of the cable, the extension amount of the electric push rod 15 is adjusted and controlled so that the sharp end of the stripping blade 5 connected to the output end of the electric push rod 15 is inserted into the corresponding insulating layer. Since the cable clamping mechanism formed at the front fixing plate 8 implements rolling contact clamping on the corresponding part of the cable, the handle 12 is rotated 360° to cut the corresponding insulating layer. Thereafter, the lead screw 2 is rotated to drive the L-shaped block 701 connected to the traction block 7, the first screw 702 and the straightening wheel 4 to move toward the end of the cable to cut the insulating layer horizontally.

[0042] Step 6: After the horizontal cutting of the insulation layer is completed, the ring cutting operation in step 5 is performed again to achieve the end-to-end ring cutting of the insulation layer, and then the end of the stripping blade 5 is located in the horizontal cutting groove and combined with the overall side rotation, which helps to peel off the insulation layer at this location;

[0043] Step 7: Replace the starting position of the stripping blade 5 and repeat the above stripping operation to complete the stripping of the entire cable end.
