[0013] 1. For this heat dissipation rack for a transformer iron core, by setting a control assembly, the slider is moved on the surface of the connecting seat. The sliding rod fixed on the surface of the slider slides by abutting against the support block through the support rod. The vertical rod fixed on the surface of the support block synchronously moves horizontally on the surface of the flat rod when stressed. When the vertical rod moves, the clamping rod fixed on the surface of the vertical rod will slide on the surface of the connecting seat and be inserted into the through hole opened on the surface of the positioning block.
