Planet wheel displacement centrifugal directional sampler suitable for extraterrestrial celestial body

The invention relates to a planet wheel displacement centrifugal directional sampler suitable for an extraterrestrial celestial body. The planet wheel displacement centrifugal directional sampler comprises a cutter assembly, a displacement assembly, a sample sealing assembly, a separation assembly and a bracket, wherein the cutter assembly is provided with a planet carrier; a plurality of same single-rotation shaft systems are evenly distributed on the planet carrier along the circumference, and a cutter can be installed on each single-rotation shaft system, wherein the single-rotation shaft system is in matched transmission with the sun gear, so that rotation of the sun gear can drive all cutters to rotate through the single-rotation shaft system, sampling of a sampling object can be achieved through rotation of the tools, and the displacement assembly is matched with the cutter assembly to drive the cutter assembly to rotate and transpose. The sample sealing assembly can be used forcollecting a sampling sam
