The carrying tray 10 is generally provided with side lugs at both sides thereof, by which the side lugs can be supported by a support sub-platform, i.e., one implementation of the aforementioned engaging portion 1211. The side lugs generally have a certain draft angle, and when the first carrying platforms 1210 at two sides are folded, the carrying tray 10 is supported by the side lugs. After the stacked boat 10 falls onto the second carrying platform 1310, the first carrying platform 1210 is folded and reset, wherein the supporting sub-platform coincides with the lateral ear of the next bottom boat 10 at the position of the plane where the first supporting platform is located, and after the transportation mechanism 1120 draws away the bottom boat 10, the upper boat 10 falls down and is further supported by the first carrying platform 1210. Of course, a stop 1212 may be disposed at the edge of the carrying surface 3231d of the first carrying platform 1210 to prevent the carrying tray 10 within the carrying range of the first carrying platform 1210 from being moved by the transportation mechanism 1120.
