The invention provides a rack for anodizing. The rack for anodizing comprises a hanging rod, wherein the hanging rod is provided with a sleeving section for corresponding workpieces to sleeve; and a first clamping structure and a second clamping structure which are matched with each other to fixedly clamp the workpieces on the sleeving section are arranged at two ends of the sleeving section. The rack for anodizing has the beneficial effects that the sleeving section is arranged on the hanging rod, the annular workpieces sleeve the sleeving section, the first clamping structure and the second clamping structure which fixedly clamp the workpieces are arranged at two ends of the sleeving section, so that fixing surfaces of each workpiece are two end surfaces, the first clamping structure and the second clamping structure are matched with each other, the effect of fixing the workpieces can be guaranteed effectively, the workpieces can be ensured to be in contact with the rack well, and then the anodizing treatment effect is improved.
