Wide-positioning-error slow-release primary packaging device for extraterrestrial celestial body surface sample collection

The invention provides a wide-positioning-error slow-release primary packaging device for collecting extraterrestrial celestial body surface samples. The device completes the packaging action under the action of the funnel and the valve torsion spring. The bottom shock excitation assembly is arranged at the bottom of the primary sealing container, and shock excitation action is completed under the combined action of a torsional spring and a shock excitation motor. The funnel assembly is connected with the track plate through a bearing, connected with the axial driving assembly through a lead screw and hinged to a swing plate in the swing driving assembly. And the funnel moves along the track of the track plate. The axial driving assembly is fixed to the swing driving assembly, and the gear motor drives the lead screw to rotate and drives the funnel assembly to complete the ascending action. A swing torsion spring is arranged in the swing driving assembly, and under the action of restoring force of the torsion
