Orientation tool for cutting three-dimensional crystal

The utility model provides a cutting three-dimensional crystal orientation tool which comprises a base, a first dial is arranged on the base, a first supporting rod is movably connected to the first dial, the first supporting rod is movably connected with a second supporting rod, a second dial and the second supporting rod are arranged at one end of the first supporting rod, and the first supporting rod is movably connected with the second supporting rod. The third dial and the clamp are arranged at the other end of the second supporting rod and movably connected with the second supporting rod. According to the tool for cutting the three-dimensional crystal orientation, a high-precision Laue method is adopted, seed crystals in any orientation can be rapidly and effectively cut, the crystal orientation deviation of the seed crystals is within 10 degrees, the efficiency of obtaining the seed crystals in specific orientation is improved, and personal errors are reduced; the tool is simple and reliable in structu
