Four-axis aircraft capable of folding in telescopic mode

The utility model relates to a four-axis aircraft capable of folding in a telescopic mode. The four-axis aircraft comprises a central supporting mechanism and four sets of propeller mechanisms. The improvement is that the four sets of propeller mechanisms are four sets of telescopic propeller mechanisms; each set of telescopic propeller mechanisms comprises a small bevel gear, a telescopic pole, a propeller, a motor and a lifting arm mechanism, and further comprises a large bevel gear and a servo motor; the servo motor, the large bevel gear and four small bevel gears form a drive mechanism of telescopic poles of four sets of propeller mechanisms; under the driving of the servo motor, the four small bevel gears respectively drive the four telescopic poles to stretch out or draw back simultaneously through thread transmission of a screw. The improvement is that the four-axis aircraft further comprises four sets of folding mechanisms, wherein each set of folding mechanisms drives each set of telescopic propeller mechanisms to be folded or unfolded. According to the four-axis aircraft, the telescopic mechanisms and the folding mechanisms are additionally arranged, so that the four-axis aircraft is greatly folded and unfolded, the size of the aircraft is effectively reduced relative to an existing product, and the four-axis aircraft is convenient to carry.
