The invention provides a spark sampling device which comprises an outer cylinder and an inner cylinder, the inner cylinder is coaxially arranged in the outer cylinder in a sliding mode, the outer cylinder and the inner cylinder are provided with an inner and outer cylinder telescopic driving mechanism, the lower end of the inner cylinder is fixedly connected with a connecting disc, the connecting disc is rotatably connected with a sampling claw to enable the sampling claw to turn over up and down, and the sampling claw is connected with the outer cylinder. A sampling claw is arranged in the inner cylinder, a groove matched with the sampling claw in shape is formed in the outer wall of the inner cylinder, a torsional spring is arranged between the connecting disc and the sampling claw, the torsional spring is used for retracting the sampling claw into the groove in the outer wall of the inner cylinder or releasing the sampling claw from the groove in the outer wall of the inner cylinder, and a sampling claw retracting and releasing mechanism is arranged in the inner cylinder. In a Mars task, the device can fly relative to the ground of the Mars and is not influenced by the geology and landform of the surface of the Mars, and the stability and the reliability of sample collection are ensured. The invention also has the characteristics of simple structure, light weight and the like.
