The first motor drives the rotating rod to rotate. Under the limitation of the first through hole, the rotating rod drives the moving rod to move through the transmission rod, and the moving rod drives the shielding plate to move. The extension direction of the first through hole is the same as the moving direction of the moving rod.

[0114] The driving assembly includes a limiting block, a moving rod, a transmission rod, a rotating rod, and a first motor.
