The power source 1 is a right-angle speed reducing motor. The first rotating pair and the second rotating pair are driven to rotate through the rotation of the right-angle speed reducing motor, so that the container 5 can perform superimposed movement of three paths of translation, rotation and overturning. The first swing arm 3 rotates relative to the first rotating shaft 2, and if the first rotating shaft 2 is used as a static reference system, the rotating direction of the mounting rack 4 is perpendicular to that of the first swing arm 3, and the same is true of the second rotating pair. When the equipment runs, the power source 1 provides power to drive the first rotating pair to move and drive the second rotating pair to move at the same time, and a power output mechanism is not additionally arranged at the position of the second rotating shaft 6.
