Two locking pins 15 are slidably installed on the first crossbar 8. The locking pins 15 cooperate with the slots. Worms 19 are rotatably installed in both pull rods 12. Two worm wheels 21 are meshed on both worms 19. The four worm wheels 21 are fixedly connected to four rotating shafts 20 respectively. A knob 18 is fixedly installed at one end of both worms 19. When the worm 19 rotates, the worm 19 drives the two worm wheels 21 to rotate. A return spring 16 is sleeved on the outer side of both locking pins 15. The two ends of the return spring 16 are fixedly connected to the outer side of the first crossbar 8 and the outer side of the locking pin 15 respectively.

[0033] In this embodiment, damping springs 4 are installed in each of the four first sliding grooves 3. The four damping springs 4 are respectively connected to the two first support rods 5 and the two second support rods 6. Two mounting grooves are opened in each of the two pull rods 12. Through holes are opened in the inner walls of the four mounting grooves. Rotating shafts 20 are rotatably installed in each of the four through holes. Hooks 17 are fixedly connected to one end of each of the four rotating shafts 20. When the rotating shafts 20 rotate, the rotating shafts 20 drive the hooks 17 to rotate.
