Supporting structure and differential parallel micro-motion platform

The invention provides a supporting structure and a differential type parallel micro-motion platform. The supporting structure comprises a first hooke joint, an actuator and a second hooke joint. One end of the actuator is connected with the first hooke hinge; the second hooke joint is connected with the other end of the actuator, and the distance between the second hooke joint and the first hooke joint is adjusted through the actuator. The differential type parallel micro-motion platform comprises a movable platform, a plurality of supporting structure assemblies and a static platform, the supporting structures are connected between the first mounting surfaces and the second mounting surfaces, and the first mounting surfaces and the second mounting surfaces connected with the same supporting structure are parallel. The actuator is used in cooperation with the hooke joints, piezoelectric ceramics are replaced with the differential transmission scheme, the cost is reduced, the supporting structure with the mic
