[0022] First, by moving the moving rod 12 up and down, the moving rod 12 drives the third gear 11 and the fourth gear 14 to move, thereby making the third gear 11 mesh with the second gear 9, or making the fourth gear 14 mesh with the first gear 5, and when the third gear 11 and the second gear 9 are meshed, the fourth gear 14 and the first gear 5 are not meshed; the fourth gear 14 and the first gear 5 are meshed so that the third gear 11 and the second gear 9 are not meshed. Secondly, since the same moving plate 17 is fixedly connected between the two threaded rods 8, the two threaded rods 8 are in a fixed state, so during the rotation of the threaded barrel 7, the threaded rod 8 will be driven to move up and down relative to the threaded barrel 7;

At this time, the moving rod 12 is moved upward, and the moving rod 12 drives the third gear 11 and the fourth gear 14 to move upward until the first gear 5 and the fourth gear 14 are meshed. At this time, the lower fixing ring 13 and the center plate 3 are abutted, and the moving rod 12 is rotated. The moving rod 12 drives the bolt 4 to rotate through the first gear 5 and the fourth gear 14, and screws the bolt 4 into the corresponding threaded hole 2 until the nut 6 and the fixing plate 1 are abutted, thereby completing the cable limiting operation.
