step S5, after the limiting pin shaft penetrates into the ear plate, starting a lifting mechanism to lift the carbon electrode clamp device; when the lifting is initial, the clamp beam is firstly lifted, and the limiting pull rod and the supporting seat are still kept still on the carbon electrode; until the ear plate of the pull rod contacts with the limit pin shaft, the clamping mechanism keeps the open state, the carbon electrode clamp device is integrally lifted, and the carbon electrode is left on the bearing surface.
