The invention provides a high-reliability high-stability multi-rotor-wing unmanned aerial vehicle with a quick-dismounting function. In order to quickly dismount the unmanned aerial vehicle, the central disc and arms of the unmanned aerial vehicle are split, fan-shaped plates with central angles of more than 180 degrees are arranged on the end surfaces of arm inner parts in arm connecting structures to serve as first limiting convex grooves, fan-shaped plates with central angles of less than 180 degrees are arranged on the end surfaces of central disc inner parts in the arm connecting structures to serve as second limiting convex grooves, and each first limiting convex groove and each second limiting convex groove are clamped together to form a round plate anti-twist structure; meanwhile, in order to prevent twisting of each anti-twist structure, two column positions are added in each connecting structure to reinforce the anti-twist effect, and the arm inner parts are integrally and fixedly connected with the central disc inner parts through thread suites on the outer sides of the formed anti-twist structures, so that the firmness of the unmanned aerial vehicle during flight is guaranteed and the anti-twist function of the arms is improved. The unmanned aerial vehicle has the advantages of simple structure, and has the advantages of quickness for dismounting and convenience for connecting and mounting; especially, the firmness and rigidity of connection are guaranteed, and the flight reliability and stability of the unmanned aerial vehicle are greatly improved.
