The invention discloses an amplitude transformer and an aircraft using the amplitude transformer, and belongs to the technical field of aircrafts, the amplitude transformer comprises two sets of double-crankshaft lever mechanisms, two sets of angle changing devices and a driving shaft, and the two sets of double-crankshaft lever mechanisms are arranged at the two ends of the driving shaft respectively; a crankshaft A at one end of the double-crankshaft lever mechanism and one end of the angle changer are connected with the driving shaft, and the other end of the angle changer is connected with a crankshaft B at the other end of the double-crankshaft lever mechanism; flapping of wings on two sides of the aircraft is realized through two sets of double-crankshaft lever mechanisms and angle changing devices. A power source is provided for flapping of the wings by a power component, and the flapping amplitude of the wings is adjusted by an angle changer. Required lift force is obtained during takeoff through the large-amplitude flapping wings, the flight height during flight is maintained through the small-amplitude flapping wings, and energy loss is reduced. The invention is flexible and convenient to adjust, the flight attitude of the device is closer to that of birds, the device can adapt to different requirements for lift force and thrust in the flight process, and the whole process becomes more energy-saving and efficient.
