The invention discloses a rapid sampling device for underground geology and geophysical prospecting, and belongs to the technical field of underground sampling. The device comprises a fixing assembly which comprises a bottom plate; a connecting assembly is mounted on the bottom plate, a rotatable winding reel is mounted on the connecting assembly, and a cable is wound on the winding reel; the sampling assembly comprises a mounting frame and a sampling barrel which are sequentially arranged from top to bottom; an air cylinder is mounted on the mounting frame, the cable is connected with the mounting frame, a sampling drill bit is arranged in the sampling barrel, and an output shaft of the air cylinder is connected with the sampling drill bit; the supporting assembly comprises a limiting plate and a telescopic assembly; the limiting plate is located on the outer side of the sampling barrel, an output shaft of the air cylinder is connected with the telescopic assembly, and the telescopic assembly is connected with the limiting plate. By arranging the supporting assembly, the problem that the sampling drill bit of the rapid sampling device shakes during sampling is solved, and the safety of the sampling process is improved.
