The invention discloses a navel orange picking device. The navel orange picking device comprises a U-shaped frame, wherein a through hole is formed in the upper surface center of the U-shaped frame, positioning threaded holes are formed in two sides of the upper surface of the U-shaped frame, positioning threaded rods are in thread connection on the inner-side surfaces of the positioning threadedholes, positioning plates are rotationally connected on the lower surfaces of the positioning threaded rods through rotating blocks, the outer surfaces of the positioning plates are glidingly connected to two ends of the inner-side surface of the U-shaped frame, connecting threaded holes are formed in two ends of the inner-side surface of each positioning plate, connecting threaded rods are in thread connection with the inner-side surfaces of the connecting threaded holes, collecting baskets are glidingly connected on the front end surfaces of the connecting threaded rods through inserting holes, and the outer surfaces of the collecting baskets are glidingly connected to the inner-side surface of the U-shaped frame. The navel orange picking device is in thread connection with the positioning plates through the U-shaped frame, so that the convenience and the stability of use can be greatly improved to ensure the picking efficiency and safety.
