When the conveyor belt 1 2 located at the front side is When the drawer slide on the rear conveyor belt 28 is transported to the right side of the outer support frame 64 through the transfer group 4, the connecting frame 693 is driven by the telescopic component 694 to cooperate with the connecting plate 691 to drive the inner support frame 63 to move upward, so that the inner support frame 63 drags the drawer slide upward, and drives the telescopic component 694 to slide to the left through the hydraulic cylinder 2 695.
