Geological profile measuring device

The invention discloses a geological profile measuring device, relates to the technical field of geological survey, and solves the problems that an existing total station prism is not supported stablyin use, occupies a large space and is liable to be damaged due to collision and the like in a prism carrying process. The geological profile measuring device comprises a telescopic support rod, wherein the lower portion of the telescopic supporting rod is slidably connected with a set of sliding adjusting bases; three sets of swing push rods are hinged to the lower portion of the sliding adjusting base in a circumferential array arrangement mode. A group of adjusting connecting rods are hinged to the rear end surfaces of each group of upper and lower protective covers; and the two groups of adjusting connecting rods are connected through a group of adjusting operating rods. Folding and unfolding of the telescopic installation ground feet are achieved, and an occupied space is reduced; meanwhile, the supporting ca
