After the shunted fasteners enter the working range of the clamping plate 415, the first electric push rod 414 operates, enabling the screw of the screw fastener to be quickly cleaned by the first cleaning brush 417, realizing the batch cleaning of the screw fasteners. At the same time, when the clamping plate 415 moves, it will push the lifting frame 504 to move accordingly. The sliding rod 510 slides along the sliding hole 509. With the cooperation of the spring 511, the nut of the screw fastener is clamped between the clamping plate 415 and the limit frame 501. The second electric push rod 506 is started, and the lifting frame 504 moves downward along the lifting hole 503 to a suitable position, enabling the second cleaning brush 505 to contact the nut, achieving targeted cleaning of the nut and improving the operation efficiency of the cleaning equipment.
