If there are foreign objects that are easy to cut, such as kites, balloons, and plastic films, the obstacle removal work begins. If there are other foreign objects that are difficult to handle, the staff will choose a suitable method to clean them up, start the driving mechanism 4, drive the gear transmission member 1 6 and the gear transmission member 2 7 to move, and then drive the blade 71 on the surface of the gear transmission member 2 7 to perform longitudinal reciprocating motion, which cooperates with the flight of the drone body 1, thereby cutting the foreign objects, while ensuring the stability of the drone itself to avoid affecting the flight of the drone.
