The screw rod 2234 is threadedly matched with the screw hole 2132. A second through hole is provided on the side wall of the frame 212 for the synchronization shaft 2232 to pass through.

[0029] It is worth noting that when the number of the transmission components 223 is two or more, since the rotation directions of the two symmetrically arranged second bevel gears 2231 are opposite, the threads of the two symmetrically arranged lead screws 2234 are arranged in opposite directions.

[0030] Exemplarily, the transmission unit 2233 may include two bevel gears, or may include a worm gear and a worm, etc. When the transmission unit 2233 includes two bevel gears, one bevel gear is sleeved on the synchronous shaft 2232, and the other bevel gear is sleeved on the lead screw 2234; when the transmission unit 2233 includes a worm gear and a worm, the worm gear is sleeved on the lead screw 2234, and one end of the worm is connected to the synchronous shaft 2232.
