When the middle driven gear 71 rotates, the projection 72 is rotated, the projection 72 intermittently pushes the driving rod 73 to move upwards, and the projection 72 is separated from the driving rod 73 along with the continuous rotation of the driven gear 71, so that the driving rod 73 moves downwards under the action of gravity. In the process, the driving rod 73 drives the moving block 9 and the fins 91 to move up and down in a reciprocating mode, so that the lower electroplating liquid can be extruded, electroplating ions settled on the lower portion are given, and the electroplating ions flow upwards, and therefore electroplating of workpieces can be completed. And the electroplated layer on the surface of the workpiece is more uniform.

It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications should not be construed as affecting the performance of the invention and its practical application.
