Specifically, a first end of the connecting rod 451 is perpendicularly connected to a second end of the telescopic plate 442.

Under the condition that the connecting rod 451 and the clamping plate 452 rotate along with the telescopic plate 442, the control unit 500 controls to open the push rod element 455, and the push rod element 455 drives the driving plate 456 and the extending plate 457 to ascend so as to increase the intercepting area of the goods; the pusher member 455 may lower the drive plate 456 and the extension plate 457 in the event that the pusher member 455 does not require interception of cargo.
