The utility model relates to a technical?equipment field, concretely relates to roll anchor clamps are electroplated to the sheet metal. The utility model provides a roll anchor clamps has the wheel on splint set up, make roll anchor clamps reduce the frictional force between roll anchor clamps and the track at the track internal motion under the drive of sheet metal, makes the transmission of sheet metal go on steadily. Holder and splint cooperate, and self elasticity of holder makes the clamping part support and leans on be in clamping state on the splint, carry out the centre gripping to the sheet metal. In the time will going up the unloading, exert the exogenic action to the holder, self elasticity of resistance holder makes the clamping part keep away from splint, forms the clearance between clamping part and the splint. Put into the clearance with the sheet metal during material loading, then cancel the exogenic action, the sheet metal just by the centre gripping between clamping part and splint, during the unloading, then direct taking off the sheet metal from the clearance can. Therefore, the utility model discloses a roll anchor clamps can realize the automatic continuous electroplating production of sheet metal.
