Both the first driving rack 320 and the second driving rack 330 are meshed with the driving gear 310 , so that the driving gear 310 rotates to simultaneously drive the first driving rack 320 and the second driving rack 330 . The first driving rack 320 is located on the first side of the driving gear 310, the second driving rack 330 is located on the second side of the driving gear 310, and the first side is set opposite to the second side, so that the driving gear 310 can simultaneously drive the first The driving rack 320 and the second driving rack 330 move in opposite directions.

Therefore, through the cooperation of the driving gear 310, the first driving rack 320 and the second driving rack 330, and the above arrangement, the driving gear 310 can simultaneously drive the first driving rack 320 and the second driving rack 330 in opposite directions. direction to move, and then drive the two ends of the flexible screen 200 to move in opposite directions.
