The invention discloses a wearable unmanned aerial vehicle and belongs to the technical field of unmanned aerial vehicles. The wearable unmanned aerial vehicle comprises an aerial vehicle body. The aerial vehicle body is a hollow box body. The two sides of the aerial vehicle body are symmetrically provided with four wing arms capable of being closed inwards towards the center of the aerial vehicle body when folded and capable of being unfolded away from the center of the aerial vehicle body in flight. The two wings on each side are connected into a whole. The bottom end of each wing arm is provided with a rotary shaft which extends into the aerial vehicle body and is hinged to the aerial vehicle body. The aerial vehicle body is provided with a folding and unfolding control and locking mechanism for controlling the wing arms to act. The folding and unfolding control and locking mechanism is provided with a folding and unfolding key extending out of the aerial vehicle body. The front end of each wing arm is provided with a motor. A power output shaft of the motor is provided with blades. The motor is connected with a power source. According to the wearable unmanned aerial vehicle, through one-key folding and unfolding structural design, the unmanned aerial vehicle can be carried conveniently as a watch.
