The invention discloses a delta structured parallel manipulator capable of moving precisely and three-dimensionally. The delta structured parallel manipulator comprises a 3-RUU kinematic chain based delta structured parallel manipulator body, a bearing main platform and a 3-PUU kinematic chain based main platform support. The delta structured parallel manipulator body is mounted on the bearing main platform and driven by a motor on the bearing main platform through a four-link transmission mechanism; the bearing main platform which is supported by the 3-PUU kinematic chain based main platform support has three spatial translation freedom degrees and is capable of moving up and down and translating. The delta structured parallel manipulator has the advantages that on the basis of the 3-RUU kinematic chain and the 3-PUU kinematic chain, the bearing main platform can acquire a spatial movement range and is capable of not only moving up and down but also translating, and accordingly a secondary movable platform (
