The invention relates to a medical camouflage net supporting rod capable of being disassembled and assembled quickly for the field. The medical camouflage net supporting rod comprises a base, rod bodies and a top disc. The rod bodies comprise the outer rod body and the inner rod body. The side wall of the lower end of the outer rod body is provided with an axial vertical through hole. Transverse through holes are formed in the upper end and the lower end of the vertical through hole in a stretching mode in the peripheral direction respectively. A ground nail is arranged at the lower end of the outer rod body in a penetrating mode. The lower end of the ground nail is a tip. A baffle perpendicular to a nail body is arranged on the ground nail. The baffle stretches out of the through hole in the side wall of the outer rod body. According to the medical camouflage net supporting rod, on the one hand, supporting plates of the top disc in the supporting rod can be folded when not used, the occupied storage space can be reduced to the maximum degree, and conveying and storage are facilitated; on the other hand, the telescopic ground nail is arranged in the rod bodies; when the base needs to be fixed to the ground, the ground nail stretches out of the rod bodies, the lower ends of the rod bodies are arranged in a sleeve of the base in a penetrating mode, the ground nail is knocked to be pinned into the ground, and the supporting effect of the supporting rod is stable.
