The utility model discloses a drill hole deformation observation instrument under a shaft. The drill hole deformation observation instrument under the shaft is designed in order to solve the problem that an existing seismic deformation observation instrument under a shaft can be stricken by lightning easily. The observation instrument comprises a comprehensive probe device arranged under the shaft of a drill hole, a data acquisition controller arranged on the ground, a light guider and a light guiding light source, a transmitter extends into the shaft of the drill hole, and the transmitter and a photovoltaic power generation panel are arranged in a spaced mode; the data acquisition controller is connected with the comprehensive probe device through data signal optical fibers. The observation instrument is designed in the way, an electric shock channel is cut off fundamentally, high-voltage thunder and lightning pulses can not enter the comprehensive probe device any more, the purposes of preventing lighting s
