Portable telescopic drawing support

The invention relates to a construction site drawing containing device, in particular to a portable telescopic drawing support. The problems that due to the fact that existing drawing placing is manually operated, time and labor are consumed, and construction efficiency is influenced are solved. The portable telescopic drawing support comprises an elliptical annular support core, five cylindrical hinges are arranged on the support core, two symmetric cylindrical hinges are connected with telescopic support arms, the other three evenly-arranged cylindrical hinges are connected with telescopic support legs, and drawing clips are arranged at the outer ends of the two telescopic support arms. The portable telescopic drawing support is reasonable and reliable in structural design, the problem that labor intensity is large due to manual operation is solved, supporting is stable, and normal use is not influenced even though it is windy. Meanwhile, unfolding and folding are convenient, carrying is facilitated, and the advantages of being simple in structure, convenient to process and low in cost are achieved.
