Subsequently, the second motor 5 is started, and the output end of the second motor 5 drives the cutting blade 6 to rotate. At the same time, the first motor 3 is started, and the output end of the first motor 3 drives the screw 2 to rotate. The screw 2 will move the nut 4 back and forth. The nut 4 drives the cutting blade 6 and the second motor 5 to move at the same time. The cutting blade 6 is used to cut the cable. After the cutting is completed, the cable is taken out and the third motor 15 is started. The output end of the third motor 15 drives the middle pulley 16 to rotate. The middle pulley 16 drives the pulleys 16 on both sides to rotate through the toothed belt 17. The pulleys 16 on both sides drive the two sets of rotating members 18 to rotate at the same time. The rotating member 18 slides between the second cylindrical pin and the second slide groove, so that the slot plate 19 moves horizontally to the middle. The slot plate 19 drives the cleaning plate 26 to move through the connecting member 20. The cleaning plate 26 pushes the debris in the third chamber to the opening, so that the debris falls into the collection box 7, and the debris is cleaned, completing the use of the device.
