Since the multi-layer support 13 is designed in a vertical manner, the space in the box can be fully utilized to place a larger number of workpieces. The box door 3 is closed, the device is started, and the motor 126 starts to work. The sun gear 123 is driven to rotate through the belt transmission mechanism 125. The sun gear 123 is engaged with the planetary gear 122, and the planetary gear 122 is engaged with the gear ring 124, thereby driving the rotating disc 121 to rotate, realizing that the multi-layer support 13 revolves around the axis of the sun gear 123 while rotating on its own axis.
