The transmission assembly comprises a pallet unit and the boxes are stacked at the upstream side of the pallet unit. The driving unit drives the circulating line body so that the boxes are transported towards the transmission assembly. The guide rod unit comprises a guide rod. An avoiding groove is formed in each bottom tray for containing the guide rod that extends towards the transmission assembly. An included angle is formed between an extending direction of the guide rod and a feeding direction of the circulating line body.
