The third shaft 16 travels on the spur rack 20 through the gear set 18, and cooperates with the support block 14 and the roller 15 to drive the first circular plate 4 and the sanding machine 3 to move. When the moving speed of the belt sander 3 needs to be adjusted, it is only necessary to adjust the other gears of the gear set 18 to mesh with the spur rack 20, start the electric push rod 21, and the electric push rod 21 drives the moving plate 22 to move on the supporting plate, and the moving plate 22 drives the sliding sleeve 23 to slide on the surface of the third rotating shaft 16, and the first slide bar 24 slides in the first slide groove 25, and the sliding sleeve 23 drives the gear set 18 to move, so that the other gears mesh with the spur rack 20. When the third rotating shaft 16 rotates, the third rotating shaft 16 drives the sliding sleeve 23 and the gear set 18 to rotate through the first slide bar 24 and the first slide groove 25; Before grinding, it is necessary to make the sanding belt of the sanding machine 3 contact with the cable surface, start the motor 9 to drive the first circular gear 11 to rotate, the first circular gear 11 drives the second circular gear 26 to rotate, the second circular gear 26 drives the second ring gear 28 to rotate, the second ring gear 28 drives the circular ring plate 27 to rotate, the circular ring plate 27 drives the four arc rods 30 to move toward the center of the first circular plate 4 through the connecting rod 29, so that the flexible rod 31 is inserted into the arc rod 30, so that one end of the adjacent arc rods 30 contacts each other, and the four arc rods 30 form a closed loop circle, the arc rod 30 can press the mounting plate 7 to move, and the mounting plate 7 drives the sanding machine 3 to move, so that the sanding belt of the sanding machine 3 contacts the cable surface, and the first spring 33 is stretched. When the motor 9 drives the circular ring plate 27 to rotate in the opposite direction, the arc rod 30 moves outward at the same time. Under the action of the first spring 33, the mounting plate 7 and the sanding machine 3 move away from the cable. Before grinding the cable, the protective cover 34 is pushed so that the protective cover 34 covers both the cable and the belt sander 3 inside, so that the flying chips generated during the grinding process will not fly around. A self-locking component is provided on the protective cover 34, which can lock the protective cover 34 on the bottom plate 1; When the sanding belt of the sanding machine 3 is pressed tightly against the cable surface, the protective cover 34 can be pushed to put the protective cover 34 in place, the cross bar 43 can contact and push the connecting plate 42, the magnet 44 can be adsorbed on the connecting plate 42, and the protective cover 34 is fixed. The connecting plate 42 can drive the plug post 39 to be inserted into the hollow cylinder 37, the second spring 38 is compressed, and the plug post 39 drives the second circular gear 26 to be out of mesh with the first circular gear 11. The subsequent motor 9 can drive the first circular gear 11 to continue to rotate, thereby driving the sanding machine 3 to move and rotate, and the first circular gear 11 cannot drive the second circular gear 26 to rotate, so that the arc rod 30 does not need to continue to move. When the protective cover 34 is opened, the cross bar 43 is not in contact with the connecting plate 42. Under the action of the second spring 38, the second circular gear 26 moves back and re-engages with the first circular gear 11. When the motor 9 drives the second circular gear 26 to rotate through the first circular gear 11, the second circular gear 26 can drive the arc rod 30 to move through the circular ring plate 27 and the second ring gear 28, so that the arc rod 30 drives the sanding machine 3 to move, and the circular ring plate 27 can drive the arc rack 50 to rotate. When the protective cover 34 is pushed to move, the second circular gear 26 moves to a position where it is not meshed with the first circular gear 11. The second circular gear 26 at this position just meshes with the rotated arc rack 50. At this time, the arc rod 30 moves into place to press the sanding belt of the sanding machine 3. The cable surface needs to keep the sanding machine 3 in this state. It is only necessary to prevent the second circular gear 26 from rotating. When the cross bar 43 presses the connecting plate 42, the connecting plate 42 drives the plug post 39 and the rectangular block 49 to move, so that one side wall of the rectangular block 49 is flush with the side wall of the first circular plate 4. Under the action of the third spring 46, the L-shaped plate 47 moves downward, and then moves back a small distance of the protective cover 34, so that the plug post 39 can drive the rectangular block 49 to be inserted into the rectangular opening 48, so that the plug post 39 can no longer rotate, thereby preventing the second circular gear 26 and the annular plate 27 from rotating.
