At the bottom end of the activity plate 302, first springs 306 are symmetrically installed. The bottom ends of the first springs 306 are fixedly connected to the inner bottom wall of the fixed box 301. A magnetic block 308 is installed on the activity plate 302. An electromagnet 307 is fixedly installed on the inner bottom wall of the fixed box 301. The electromagnet 307 is externally connected to a power supply and a rheostat. The resistance value of the rheostat is controlled by the controller 2. At the top end of the activity plate 302, longitudinal rods 303 are symmetrically installed. The longitudinal rods 303 penetrate above the fixed box 301. At the top ends of the longitudinal rods 303, a mounting seat 304 is fixedly installed. A tensioning wheel 305 is rotatably installed on the mounting seat 304. The tensioning wheel 305 is in contact with the bottom wall of the cable. Under the elastic force of the first spring 306, pressure can be exerted on the cable, so that the cable remains taut. When the tension needs to be adjusted, the electromagnet 307 is controlled to be energized, and the repulsive force generated by the electromagnet 307 is controlled through the rheostat. The electromagnet 307 generates a repulsive force on the magnetic block 308, thereby adjusting the tensioning force of the tensioning wheel 305 on the cable.

[0025] The cable limiting component 4 includes two side plates 401 fixedly installed on the base 1. A lower limiting wheel 402 is rotatably installed between the two side plates 401. An upper limiting wheel 403 is provided above the lower limiting wheel 402. A guiding gap is provided between the lower limiting wheel 402 and the upper limiting wheel 403. On both sides of the upper limiting wheel 403, sliders 405 are symmetrically provided. The upper limiting wheel 403 is rotatably connected to the two sliders 405. The sliders 405 are slidably installed on the sliding grooves 404. The two sliding grooves 404 are symmetrically opened on one side of the two side plates 401 close to each other. At the bottom end of the slider 405, a second spring 406 is fixedly installed. The bottom end of the second spring 406 is fixedly connected to the inner bottom wall of the sliding groove 404. At the top end of the sliding groove 404, a rod groove 407 is opened. The rod groove 407 penetrates to the top end of the side plate 401. A pressure rod 409 is movably installed inside the rod groove 407. The bottom end of the pressure rod 409 is in contact with the top wall of the slider 405. At the top end of the pressure rod 409, a cross plate 408 is fixedly installed. A top frame 410 is fixedly installed at the top end of the side plate 401. The cross plate 408 is located inside the top frame 410. A screw rod 412 is rotatably installed on the top frame 410. The screw rod 412 is threadedly connected to the cross plate 408.

The motor 411 is controlled by the controller 2. The cable passes through between the upper limiting wheel 403 and the lower limiting wheel 402. When the motor 411 is started, the upper limiting wheel 403 moves downward, so that the lower limiting wheel 402 and the upper limiting wheel 403 are in contact with the outer wall of the cable, which is convenient for limiting cables with different diameters. At the same time, the downward movement of the upper limiting wheel 403 can also press and position the cable, which is convenient for processing the cable.

[0026] Working principle: During operation, first pass the cable to be processed through between the lower limit wheel 402 and the upper limit wheel 403 on one side, then pass above the tension wheel 305, and then pass through between the lower limit wheel 402 and the upper limit wheel 403 on the other side to complete the installation;

[0027] Turn on the motor 411 to make the screw 412 rotate. Since the cross plate 408 is threadedly connected to the screw 412, it drives the pressure rod 409 to move downward, thereby pushing the upper limit wheel 403 downward until the lower limit wheel 402 and the upper limit wheel 403 contact the outer wall of the cable, which is convenient for limiting cables with different diameters. At the same time, the downward movement of the upper limit wheel 403 can press and fix the cable, which is convenient for processing the cable part between the two cable limiting components 4;

[0028] At the same time, the tension wheel 305 contacts the bottom wall of the cable. Under the elastic force of the first spring 306, it can generate a pressure on the cable to keep the cable taut. When the tension needs to be adjusted, control the electromagnet 307 to be energized, and control the repulsive force generated by the electromagnet 307 through the sliding rheostat. The electromagnet 307 generates a repulsive force on the magnetic block 308, thereby adjusting the tension force of the tension wheel 305 on the cable.
