Sampling device

The invention provides a sampling device, and relates to the technical field of geological sampling. The sampling device comprises a bottom shell, a sampling mechanism, a rotating mechanism for adjusting the direction of the sampling mechanism and an auxiliary mechanism for positioning the sampling mechanism, wherein the rotating mechanism comprises a rotating shell with a rotating function. According to the sampling device, through cooperation of an electric telescopic rod, a rotating shell, a rotating motor and a moving motor, the moving motor is started, an output shaft of the moving motor drives a gear to rotate, and the gear rotates to drive a sliding shell to slide in the direction of a rack rod, so that the sliding shell slides into the inner wall of the rotating shell, and then a sampling drill bit is detached; secondly, a rotating motor is started, and an output shaft of the rotating motor drives a rotating shell to rotate around the output shaft of the rotating motor, so that the angle of the sampli
