[0051] When the first rack 290 moves back and forth, it synchronously drives the traction frame 291 to move left and right. When the traction frame 291 moves left and right, it drives the lower end of the lever connecting arm 450 to move left and right, so that the middle of the lever connecting arm 450 rotates on the movable groove 160 to perform a lever movement. When the bottom of the lever connecting arm 450 moves to the left, the top of the lever connecting arm 450 moves to the right. When the bottom of the lever connecting arm 450 moves to the right, the top of the lever connecting arm 450 moves to the left, so that the top of the lever connecting arm 450 drives the second rack 44 0 moves left and right, when the second rack 440 moves left and right, the meshing drives the first gear 460 to reciprocate, the first gear 460 synchronously drives the second gear 470 to reciprocate, the second gear 470 drives the top and bottom sliding links 480 to open and close through the third rack 481, the sliding link 480 synchronously drives the jacket 490 to open and close, the jacket 490 is unfolded to wrap the wire rope of the fried wire in the jacket 490, and the jacket 490 presses the fried wire of the wire rope onto the wire rope when it is closed;
