Weak gravitational star surface particle sample collection device

The invention provides a weak gravitational force star surface particle sample collection device. The weak gravitational force star surface particle sample collection device comprises a base, a trigger rod, a knocking cone and a plurality of spiral clusters. Wherein the spiral clusters are located at the lower end of the base, the knocking cone is located in the trigger rod, the base is provided with a first cavity, and high-pressure gas is contained in the first cavity. When the trigger rod makes contact with the star catalogue, the trigger rod enters the first cavity, high-pressure gas enters the trigger rod to push the knocking cone to move towards the end, close to the spiral cluster, of the base, and therefore the knocking cone makes contact with the star catalogue to generate small particles. The weak gravitational star catalogue particle sample collection device knocks a star catalogue when touching the star catalogue, a large number of small particles are generated through knocking, collection of the
