The invention relates to a quick-assembly type rotor wing supporting rod assembly. The quick-assembly type rotor wing supporting rod assembly comprises a rotor wing supporting rod. The rotor wing supporting rod is fixedly connected with a fixing wing of an aircraft by a connecting structure. The fixing wing comprises a wing front beam and a wing rear beam. The connecting structure comprises a wingmiddle rib, a wing connecting plate and two connecting lug pieces. The wing middle rib comprises a middle rib middle part. Two ends of the middle rib middle part are correspondingly connected betweenthe wing front beam and the wing rear beam in a clamping mode. The bottom end of the middle rib middle part is fixedly connected with the wing connecting plate by a connecting piece. The rotor supporting rod is fixed to the wing connecting plate by the two connecting lug pieces. The rotor wing supporting rod assembly can be conveniently connected with a fixing wing of an existing unmanned fixingwing aircraft to form a vertical taking-off and landing unmanned fixing wing aircraft, and has the advantages of achieving fixed-pointed taking off and landing, being free from a runway and quick level flight.
