[0026] By aligning the hole opened on the connecting frame 501 with the damping rod 11, since two groups of damping rods 11 and the connecting frame 501 are provided, the connecting frame 501 drives the first coil sleeve 4 to move horizontally downward. At this time, the ratchet 506 is meshed with the tooth plate 505. During the descent of the connecting frame 501, the ratchet 506 is driven to rotate, thereby driving the fourth bevel gear 507 to rotate, so that the first bevel gear 508 drives the first rotating rod 509 to rotate, and the second bevel gear 510 drives the third bevel gear 511 to rotate, thereby driving the four screws 512 to rotate synchronously, and through the limitation of the sliding rod 516, the second moving plate 515 drives the fixer 514 to clamp and fix the damping rod 11.
