A telescopic hinge type multi-configuration variable space folding and unfolding mechanism comprises a base, a frame connecting rod, a swing rod, a connecting hinge, a two-degree-of-freedom composite hinge I, a two-degree-of-freedom composite hinge, a secondary telescopic lever and a composite hinge connector. A plurality of configuration states such as a cuboid, a tetrahedron, a pentahedron, a rectangular pyramid, a folding state and a plane state can be obtained through motion changes of the rod pieces, and the folding mechanism has the advantages of being large in folding ratio, high in reliability, high in stability, simple in space folding and the like and can be applied to the fields of spacecraft basic frameworks, large-diameter folding and unfolding antennas, large solar panel supports and the like. And the method has relatively high adaptability and practicability.
