Multi-section continuous structure hand rehabilitation exoskeleton

The invention discloses a multi-section continuous structure hand rehabilitation exoskeleton, and relates to the technical field of rehabilitation medical robots. The problem that driving force of a flexible exoskeleton is insufficient is solved, and the safety problem caused by the fact that the finger rotation center of a patient of a rigid exoskeleton does not coincide with the rotation center of the exoskeleton is solved. The hand rehabilitation exoskeleton comprises a fixing plate assembly, a thumb rehabilitation exoskeleton, an index finger rehabilitation exoskeleton, a middle finger rehabilitation exoskeleton and a ring finger and little finger rehabilitation exoskeleton. The index finger rehabilitation exoskeleton comprises two first lead screw sliding block mechanisms, two first spring steel sheets and a plurality of first connecting blocks; the first connecting block is provided with a first guide sliding groove and a second guide sliding groove, one ends of the two first spring steel sheets are con
