Multi-folded umbrella-shaped reflector

Disclosed is a multi-folded umbrella-shaped reflector. The multi-folded umbrella-shaped reflector comprises a central column (1), a fixed disk chuck (2) and a movable disk chuck (3), wherein a central fixed surface (7) is mounted at the top end of the central column (1); the fixed disk chuck (2) and the movable disk chuck (3) are both mounted on and are coaxial with the central column (1); the fixed disk chuck (2) is fixedly mounted below the central fixed surface (7); the movable disk chuck (3) is arranged below the fixed disk chuck (2) and can move along the central column (1); foldable ribs (4) are distributed in a circumferential direction using the central column (1) as the center; and a reflecting surface (5) is laid on the foldable ribs (4). For solving the problems of low unfolding rigidity, low profile precision, unsatisfactory storage ratio and the like of an existing foldable umbrella-shaped reflector, the invention provides the multi-folded umbrella-shaped reflector having the advantages of high s
