The driving member 21 in this embodiment may be a conventional motor (not shown) that directly or indirectly drives the conductive shaft 12 or the hanging plate 11 to rotate by using a driving shaft. Since the conductive posts 13 are used to facilitate the movement of the contact point of the workpiece 30 by gravity along with the rotation of the hanging plate 11, the present embodiment is preferably applied to the electroplating of a ring-shaped workpiece.
