The sliding plate 9 is slidably connected in the limiting cavity 4, and a clamping block 10 is fixedly connected to the end face of the sliding plate 9 away from the cushion block 2. The clamping block 10 is wedge-shaped, and a clamping groove 11 is provided on the supporting cross beam 3. The clamping block 10 slides through the column 1 and is matched with the clamping groove 11. A sliding opening is provided on the inner wall of one side of the limiting cavity 4, and a pressing block 17 is fixedly connected to one side wall of the sliding plate 9, and the pressing block 17 is slidably connected in the sliding opening;

[0022] The fixing assembly includes two threaded rods 12 rotatably connected to the inner wall of the fixing cavity 6 away from the supporting beam 3. The two threaded rods 12 are fixedly connected with a worm gear 13. The two worms 7 are respectively meshed with the two worm gears 13. The two worms 7 are fixedly connected with a sprocket 14. The two sprockets 14 are transmitted by a chain 15. The two threaded rods 12 are threadedly connected with a clamping block 16. The two clamping blocks 16 are provided with anti-skid pads to improve the friction between the clamping blocks 16 and the supporting beam 3 and improve the stability of the supporting beam 3.
