Skid locking device

The utility model discloses a skid locking device which comprises a base, a rotating shaft which is vertically sleeved on the base, a plate spring and an eccentric pin which penetrates through one end of the base and is connected with the rotating shaft, one end of the plate spring is fixed on the base, and the other end of the plate spring is abutted against and contacted with the outer wall surface of the rotating shaft. A flow guide groove is formed in the outer wall face of the rotating shaft, and in the length direction of the rotating shaft, the two ends of the flow guide groove extend to the two ends of the rotating shaft correspondingly. The electrophoretic paint can flow down along the flow guide grooves formed in the rotating shaft, and the contact area between the plate spring and the rotating shaft can be reduced through the flow guide grooves, so that the electrophoretic paint accumulated between the plate spring and the rotating shaft is reduced. The flow guide groove can also increase the area
