[0014] The second cathode rod is installed with an insulating sleeve.

[0015] A roller shaft for contacting the second cathode rod is installed in the plating tank, and the height of the roller shaft is adjustable.

[0016] The beneficial effects of the present utility model are:

The supporting roller 7 on the supporting seat 6 supports the second cathode rod 4, facilitating the rotation of the second cathode rod 4. During electroplating, electricity is simultaneously applied to the first cathode rod 2 and the second cathode rod 4, thereby ensuring uniform electroplating of the rotor and improving the electroplating quality.

[0030] In the embodiment, as Figure 1 、 Figure 3 shown, the supporting seat 6 includes a first supporting seat 61 arranged on the outer wall of the plating tank 1 and a second supporting seat 62 arranged inside the plating tank 1. The second supporting seat 62 is equipped with a lifting mechanism 8. The first supporting seat 61 and the second supporting seat 62 respectively support the second cathode rod 4, facilitating the stable rotation of the second cathode rod 4. When it is necessary to install the rotor and move the second cathode rod 4, the second supporting seat 62 can be lowered to facilitate the forward and backward movement of the second cathode rod 4. A sealing member is provided between the second cathode rod 4 and the plating tank 1.

[0031] In the embodiment, as Figure 1 、 Figure 3 shown, the lifting mechanism 8 includes a mounting seat 81 that cooperates with the second supporting seat 62. A rotating shaft 82 is arranged inside the mounting seat. An eccentric wheel 83 for supporting the second supporting seat 62 is installed on the rotating shaft 82, and a handle 84 is equipped on the rotating shaft 82. By rotating the eccentric wheel 83, the second supporting seat 62 can be lifted and lowered, with a simple structure and convenient operation.
