[0024] Specifically, rotate the fixing frame 4 to drive the first screw rod 2 to rotate. Through the threaded connection between the first screw rod 2 and the box body 1, the fixing frame 4 is fixed on the box body 1. After the fixing frame 4 and the box body 1 are in contact, the positioning rod 12 and the positioning hole 13 are on the same horizontal line. The positioning rod 12 is inserted into the interior of the positioning hole 13. Through the clearance fit between the positioning rod 12 and the positioning hole 13, the fixing frame 4 is fixed. Under the action of the rotating rod 5, the pulley 6 is driven to rotate.

[0025] In this embodiment, a driving component is provided between two adjacent mounting plates 3. The driving component includes two driving rods 9. Both of the two driving rods 9 are movably connected to the opposite side surfaces of two adjacent mounting plates 3 through bearings respectively. A second screw rod 10 with one end extending into it is movably connected to the opposite side surface of each of the two driving rods 9. The second screw rod 10 is fixedly connected to the limiting plate 11. Support grooves 7 are formed in the top surfaces of the two mounting plates 3.

After the fixing frame 4 and the box body 1 are fitted, the positioning rod 12 and the positioning hole 13 are located on the same horizontal line, and the fixing rod 15 is pulled to deform the fixing rod 15, so that the fixing rod 15 is separated from the fixing groove 14, and the driving rod 9 is rotated to make the driving rod 9 rotate. Through the threaded connection between the driving rod 9 and the second screw rod 10 and the sliding connection between the support plate 8 and the support groove 7, the second screw 10 drives the limiting plate 11 to move, and the positioning rod 12 is inserted into the interior of the positioning hole 13. Through the clearance fit between the positioning rod 12 and the positioning hole 13, the fixing frame 4 is fixed, and the fixing rod 15 is pushed to reset the fixing rod 15. The fixing rod 15 is inserted into the interior of the fixing groove 14, and the rubber ring 16 fits with the fixing groove 14 to fix the driving rod 9. Under the action of the rotating rod 5, the pulley 6 is driven to rotate.
