Through the setting of the rotating component 1, the first gear 15 is driven to rotate when the servo motor 14 is powered on, and the rotating shaft 12 is further driven to rotate through the engagement of the second gear 16, thereby driving the fixed frame 3, the spring sheet 4 and the movable frame 5 to rotate in a circle through the rotating platform 13, thereby realizing the rotation adjustment of the discharge position of the loading tray of the movable frame 5, and facilitating the docking of the discharge position.
