The invention belongs to the technical field of telescopic supporting rods, and particularly relates to a cold extrusion forming method for a telescopic supporting rod and the telescopic supporting rod. A metal raw material is subjected to two-stage annealing and cold extrusion treatment after coating, and then a part is subjected to heat treatment reinforcement, so that the telescopic supporting rod which is formed through pure cold extrusion and high in strength is manufactured. The telescopic supporting rod component is simple in structure, high in fatigue resistance and light in weight, the product quality of the telescopic supporting rod component is effectively improved, various metal treatment modes are creatively integrated and arranged in the whole machining process, and the telescopic supporting rod component has remarkable substantive features.
