1. A trans-media unmanned aerial vehicle device, comprising:
a housing, and
a piston arranged in the housing and capable of reciprocating in the housing,
wherein one end of the housing is provided with an opening; several flying wings are uniformly arranged in a circumferential direction of the piston; the flying wings are rotatably connected to a side of the piston facing the opening and configured to spread or retract; and under the pushing of the piston, the flying wings spread to an outside of the housing and retract back into the housing upon release of the piston, wherein the piston comprises a piston head, a piston tail, and a piston rod for connecting the piston head to the piston tail; and the piston tail is located outside the housing and is capable of closing the housing.
