Electroplating clamp for laboratory

The electroplating clamp for the laboratory comprises a length adjusting device, a cathode side rotating clamp and an anode side rotating clamp, a shaft I and a shaft II are welded to the two ends of the length adjusting device respectively, and the cathode side rotating clamp and the anode side rotating clamp are rotationally connected with the shaft I and the shaft II respectively. The length adjusting device comprises a slideway and a sliding plate, the slideway and the sliding plate are in sliding connection, the slideway is in a semi-I shape with an upward opening part, the sliding plate is a cuboid, strip-shaped holes are formed in the bottom face of the slideway, 3-5 round holes corresponding to the strip-shaped holes are formed in the sliding plate, bolts penetrate through the strip-shaped holes and the round holes to fix the slideway and the sliding plate, and the slideway and the sliding plate are locked through matched nuts. The clamp is arranged at the bottom of an electroplating container in the
