The invention relates to a retractable folding quad rotor which comprises a central supporting mechanism and four sets of propeller mechanisms. The improvement of the retractable folding quad rotor is as follows: the four sets of propeller mechanisms are four sets of retractable propeller mechanisms with identical structures; each set of retractable propeller mechanism comprises a bevel pinion, a telescopic rod, a propeller, a motor and a lifting arm mechanism, and also comprises a large conical gear and a servo motor; the servo motor, the large conical gear and the four bevel pinions form driving mechanisms of telescopic rods of the four sets of propeller mechanisms; and under the drive of the servo motor, the four bevel pinions respectively and simultaneously drive the four telescopic rods to realize outward retraction or inward retraction by virtue of screw drive of the screw rods. According to the improvement, four sets of folding mechanisms are arranged, wherein each set of folding mechanism drives each set of telescopic propeller mechanism to fold or unfold. According to the quad rotor, the telescopic mechanisms and the folding mechanisms are additionally arranged, so that the four-rotor body is greatly retracted; and compared with the conventional product, the retractable folding quad rotor disclosed by the invention has the advantages that the size of the quad rotor is effectively reduced, and the quad rotor is convenient to carry.
