[0039] The working principle of this embodiment is:

[0040] First, input the movement distance of the slide 7 through the touch display 33. When cutting, release the cable through the retracting mechanism, so that the cable enters above the support platform 6 and reaches above the bearing seat 29. Then control the first hydraulic cylinder 3 to extend, drive the pressure block 5 to descend, and press the cable on the support platform 6 through the pressure block 5. Then control the third hydraulic cylinder 27 to extend, drive the pressure plate 28 to descend, and press the cable tightly on the bearing seat 29. Then start the third motor 24 to drive the slide 7 to move to the set position, thereby pulling the cable to the set position. Then control the second hydraulic cylinder 4 to extend, and cut the cable through the cutting mechanism. After cutting, the fan 11 works to blow air into the cavity 9 of the support platform 6. The wind blows to the thread end through the through hole 10, causing the thread end to rise up. Then, the clamping mechanism is driven to move toward the support platform 6 through the horizontal displacement mechanism, and then the thread end is clamped by the clamping mechanism, and the cable is pulled to perform the next cutting.
