In this way, when the power member 41 drives the moving plate 30 to move, the sliding assembly 423 guides the movement, and meanwhile, since the sliding range of the sliding assembly 423 is limited by the first limiting assembly 421 and the second limiting assembly 422, the maximum moving distance of the moving plate 30 is the distance between the first limiting assembly 421 and the second limiting assembly 422.
