Defective product sorting equipment suitable for special-shaped nuts

The invention relates to defective product sorting equipment suitable for special-shaped nuts. The defective product sorting equipment comprises a base table, a vibration feeder, a conveying mechanism, a thickness size detection unit, a threaded hole detection unit, a defective product sorting mechanism, a good product box and an unqualified product box. The vibration feeder is used for continuously inputting the special-shaped nuts to the conveying mechanism. The conveying mechanism is used for driving the special-shaped nuts to directionally flow. The thickness size detection unit and the threaded hole detection unit are arranged at the two sides of the conveying mechanism respectively. After the special-shaped nuts flow to the detection station, the thickness size detection unit acts to detect whether the thickness size of the special-shaped nuts meets the quality inspection standard or not, and at the same time, the threaded hole detection unit acts to detect whether the relative position, the aperture an
