These fruits will first come into contact with the top plate 17 and squeeze the top plate 17. After being squeezed, the top plate 17 will transfer the pressure to the damping spring 16 so that The damping spring 16 is in a compressed state. When the damping spring 16 is compressed, it absorbs the impact generated when the fruit collides with the top plate 17, reducing the impact of the fruit colliding with the top plate 17.
