Specifically, in case that the inside of the containing unit 200 needs to be refrigerated, the control unit 700 controls to turn on the refrigerating unit 300; in case that it is necessary to move the box unit 100, the control unit 700 controls to turn on the turnover motor 510, and the turnover motor 510 turns over the buffer member 550 and the moving member 560 through the driving gear 520, the transmission member 530, and the driven member 540, so that the rolling member 562 of the moving member 560 contacts the ground and lifts up the box unit 100, and then the worker may pull the box unit 100 through the handle unit 400.

In the case that the control unit 700 controls to turn on the moving unit 500, the control unit 700 firstly controls to turn on the turnover motor 510, and after the turnover motor 510 drives the moving element 560 to turn over to be perpendicular to the ground through the driving gear 520, the transmission element 530, the driven element 540 and the buffering element 550, the control unit 700 then controls to turn on the driving motor 563, so that the driving motor 563 drives the rolling element 562 to rotate.
