The invention provides an aircraft deformable wing mechanism, which realizes the unfolding and locking of wing surfaces on two sides of a wing body fusion aircraft at any angle, and can change the aerodynamic configuration according to different flight heights and speeds of the aircraft so as to obtain the maximum aerodynamic benefits of corresponding working conditions. A four-connecting-rod mechanism is adopted for changing linear drive into rotation around a shaft, and a driving unit is used for controlling a pair of airfoils to move symmetrically. The airfoil is stored in a wing box structure, and an airfoil unfolding mechanism is isolated from an aircraft cabin. Front and rear groups of auxiliary supporting rods and supporting chutes at the front and rear ends of the airfoils are designed to play a role in auxiliary supporting of the airfoils together. The aerodynamic configuration of the aircraft is changed by changing the area of the airfoils, the bearing capacity is further improved, and the aircraft is suitable for rocket boosting and other complex and harsh mechanical working conditions of high-speed flight, large overload and strong vibration.
