An arm is hinged inside the connecting mechanism. Receiving mechanisms are arranged on both sides of the opposite surface of the housing. In the utility model, by respectively arranging connecting plates on both sides of the housing, a groove is opened in the middle of the top of the connecting plate, a number of evenly distributed springs are fixedly connected to the bottom of the groove, an adjusting plate is fixedly connected to the top of the spring, and by pressing a button, the sliding columns on both sides of the adjusting plate can slide inside the sliding groove, so that the adjusting plate can be moved up and down, thereby driving the blocking blocks at both ends of the top of the adjusting plate to move up and down. When the arm rotates, the arm is received by the up - and - down movement of the blocking blocks, solving the problems that most of the existing unmanned aerial vehicle frames have complex structures and large weights or simple structures and are not foldable.
