The invention discloses a multi-rotor unmanned aerial vehicle and belongs to the technical field of unmanned aerial vehicles. The multi-rotor unmanned aerial vehicle comprises a body, arms, motors, rotors, protection frames, scaffolds and the like and is characterized in that a hanging bracket is further arranged on the body and comprises a hook, a hanging rod, a base and rotating shafts, wherein the hook is arranged at the upper end of the hanging rod, the base is arranged at the lower end of the hanging rod, the rotating shafts are arranged on the base and located in the clamping positions of the body, and the hanging bracket can rotate around the rotating shafts. During use, the multi-rotor unmanned aerial vehicle can be hung on an object in a high position through the hook on the hanging bracket. The multi-rotor unmanned aerial vehicle in the hanging state doesn't need battery power for supplying lift force, and the working time of airborne working equipment in a take-off and landing process can be prolonged greatly. The multi-rotor unmanned aerial vehicle can be widely applied to the field of fixed point monitoring in the air, surveillance, shooting, environmental monitoring, field scientific investigation, case reconnaissance, city management, courtyard security and protection, vehicle guard, express transportation and the like.
