A wing torsion mechanism increasing flapping flight lift force comprises combined double beams, two wings, two supports and two electrodes. The combined double beams vibrate to drive the wings. The two wings provide aerodynamic lift force. The two supports are provided with two supporting holes and two limiting corners, wherein the two supporting holes are formed in the two sides respectively and serve as the torsion pivots of the wings, and the two limiting corners are arranged on the two sides respectively, provide space for torsion of the wings and limit the maximum angle of torsion of the wings. The two electrodes are connected to the positive electrode and the negative electrode of a direct-current power source and used for stimulating the combined double beams to vibrate. Different from an existing wing torsion mechanism of a miniature ornithopter, the wing torsion mechanism has the advantages that the wings are twisted through the supporting holes and the limiting corners, a better combination of wing flapping and twisting is achieved with the structure simplified, the aerodynamic performance is better, and therefore the flapping flight lift force can be greatly increased.
