Variant type fixed-wing aircraft with foldable wings

The invention belongs to the technical field of aircrafts, and particularly discloses a variant fixed-wing aircraft with foldable wings, which comprises an aircraft body, the wings are arranged on one side of the aircraft body, a first fixing rod is fixedly connected to the inner wall of the aircraft body, a first fixing frame is arranged on one side, close to the aircraft body, of each wing, and the first fixing frame is L-shaped; the side, close to the first fixing rod, of the first fixing frame is rotationally connected with the surface of the first fixing rod, and the side, away from the first fixing rod, of the first fixing frame is rotationally connected with a first transmission rod. When the aircraft is folded backwards, a sliding table is driven to move and drives a first connecting rod and a first transmission rod to rotate, so that a first fixing frame rotates on a first fixing rod, the wings are folded backwards, and the gravity center position of the aircraft is actively controlled through longit
