The invention discloses a portable X-ray diffractometer which comprises an X-ray tube, an incident diaphragm, a reflective measuring head, a transmissive measuring head and a receiving diaphragm. The portable X-ray diffractometer is characterized in that the measuring heads are mounted on a multi-shaft mechanical hand; a detector and a light tube are mounted on the reflective measuring head; an angular instrument and a detector are mounted on the transmissive measuring head. A to-be-measured workpiece or sample is unmoved, and the measuring head is driven by the mechanical hand to conduct scanning motion on the to-be-measured workpiece in space to finish measurement. The portable X-ray diffractometer can quickly and accurately control the position and the angle of the measuring head and accurately measure the diffraction angle under the condition that the to-be-measured workpiece is unmoved, can use the X-ray tube of a conventional metal target to measure the diffraction spectrum by adopting a reflective diffraction light path, and can also use the X-ray tube of a heavy metal target to measure the diffraction spectrum by adopting a transmissive diffraction light path.
