The unmanned aerial vehicle is reasonable in design structure; through the cooperative design of the rotating disc, the fixing blocks, the arc-shaped frames, the sliding grooves, the sliding blocks, a top plate, limiting plates and rolling wheels, when the unmanned aerial vehicle deviates in the air, due to the gravity effect, the sliding blocks can slide in the sliding grooves, and the rolling wheels can reduce friction force between the sliding blocks and the inner walls of the sliding grooves; therefore, the camera device is always in the original state, and the shooting quality is greatly improved.
