Abstract

The utility model relates to a universal space double-location rotating mechanism comprising a big rotating station as a base of the rotating mechanism for carrying other components of the rotating mechanism and driving carried objects to rotate. An incident ray carrying station is arranged on the big rotating station for carrying an emission device of incident rays. A small rotating station is arranged on the incident ray carrying station for carrying a planar frame capable of rotating around a shaft of a planar frame carrying station. A planar carrier is arranged on the planar frame, and can rotate in the planar frame around the center of the planar carrier. Planar objects are arranged on the planar carrier. Four rotating mechanisms are mutually alone, and all can realize the rotation of 360 degrees corresponding to a plane or surrounding the shaft. Four rotating structures all depend on the plane of the base to rotate without adding an extra rotating inertia structure thereby realizing high rotating precision. The rotating mechanism releases a generating mechanism of the incident rays and reflected rays to be a fixing mechanism.
