The invention provides a passive conical auxiliary guiding and clamping mechanism, and relates to the field of recycling of unmanned aerial vehicles. The passive conical auxiliary guiding and clampingmechanism comprises a plurality of rib plates, an annular connecting rope, resetting elastic assemblies, a seat ring and a base; the seat ring is mounted on the base; the rib plates are arranged on the seat ring in the peripheral direction; one end of each rib plate is mounted on the seat ring and can rotate relative to the seat ring; each resetting elastic assembly is further mounted at one endof the corresponding rib plate; the other ends of the rib plates penetrate in the annular connecting rope; and the rib plates form a conical structure in a surrounding manner. A through hole which allows recycling equipment to penetrate through is formed in the base. The passive conical auxiliary guiding and clamping mechanism has the advantages that the recycling site is small, requirements for unmanned aerial vehicles are low, and the passive conical auxiliary guiding and clamping mechanism can be used in different environments.
