The utility model relates to a large-aperture elastic modulus instrument probe and effectively solves the problem about testing of elasticity modulus of large-aperture borehole. The structure of the large-aperture elastic modulus instrument probe is as follows: a jack is mounted on a fixing bracket and connected with a pressure sensor mounted on the fixing bracket; a steel partition board is mounted at the rear end of the jack; a front bearing plate is mounted at the front end of the jack; a displacement sensor is mounted between the front bearing plate and the jack; one end of an internal thread sleeve rod is vertically mounted in the center of the steel partition board, and the other end of the internal thread sleeve rod is vertically mounted in the center of a rear bearing plate; an internal thread sleeve in contact with the steel partition board is mounted on the internal thread sleeve rod; an amplifier mounted a position, close to the jack, of the fixing bracket and is connected with the pressure sensor
