The invention provides a hook joint formed by cross reed flexible joints, relates to the technical field of compliant mechanisms and solves the problems that at present, the biggest stroke of a compliant mechanism ranges from +/- 5 degrees to +/- 10 degrees, and the compliant mechanism can not fit with occasions with large turning angles. According to the technical scheme, four installation locating holes are formed in a core body, the four installation locating holes are connected with one ends of four flexible rotation joints respectively, the four flexible rotation joints are defined as a first flexible rotation joint, a second flexible rotation joint, a third flexible rotation joint and a fourth flexible rotation joint respectively, the other end of the first flexible rotation joint and the other end of the third flexible rotation joint are connected with a first support, and meanwhile the other end of the second flexible rotation joint and the other end of the fourth flexible rotation joint are fixedly connected with a second support. The hook joint is used for large stroke precise transmission mechanisms and the field of flexible transmission.
