After the protective cover 6 has been used for a long time, the staff starts the first motor 12 to make its output shaft end drive the bidirectional screw rod 11 to rotate. The rotating bidirectional screw rod 11 drives the two sliders 10 and the vertical plate 2 to move away from each other along the direction of the slide groove 9 by screwing in the thread, so that the two baffles 4 move away from each other. After that, the staff pulls the protective cover 6 to make the limit plate 8 disengage from the limit groove 7, which is convenient for the staff to quickly disassemble the line protective cover 6. Then the staff aligns the positioning groove 401 at one end of the new protective cover 6 with the corresponding positioning plate 501 and inserts the protective cover 6 into the roller body of the line roller 5. Then the staff controls the output shaft of the first motor 12 to reverse, so that the two baffles 4 are close to each other, so that the position of the protective cover 6 is fixed. By setting a quickly detachable protective cover 6, it is possible to effectively protect the line roller 5 for a long time, prevent the rope column from being severely worn and causing the tail cable to slip or break when tightened, and avoid safety hazards.
