The invention discloses a lifting support column with an elastic buffer function. The lifting support column comprises a first sealing cylinder body and a second sealing cylinder body, wherein the first sealing cylinder body is internally provided with a piston; the upper part of the piston is connected with a connecting rod; a supporting plate is arranged on the other end of the connecting rod; the lower end of the first sealing cylinder body is connected with a piston which is arranged in the second sealing cylinder body; a gap between the upper end of the second sealing cylinder body and the first sealing cylinder body is sealed; hydraulic oil is provided at the lower end of a piston sheet in the second sealing cylinder body; and a plurality of air holes are formed in the upper end face of the first sealing cylinder body. The lifting support column overcomes the deficiencies in the prior art, and is reasonable in design and compact in structure; through the improvement on the basis of the conventional hydraulic cylinder, an air cylinder with the buffer function is designed, and a return spring structure is arranged at the upper end of the air cylinder, so that the pressure-bearing buffer effect is further improved.
