Under the vibration adjustment of the posture adjusting mechanism 4, the long axis of the mango is parallel to the axis direction of the rotating shaft 16. The adjusted mango continues to move on the conveying belt 1. The first branch plate 22 is relatively thin, and the adjusted mango is smoothly moved onto the first branch plate 22. Under the action of the driving assembly, the mango slides from the first branch plate 22 to the second branch plate 23 and is turned over. The inspected side of the mango contacts the second branch plate 23, and then slides along the inclined second branch plate 23 to the conveying belt 1, and is inspected by the downstream staff, so as to select another mango with a defect.
