Further, described in two, chuck includes Gripper body, and described fastening device comprises the buckling groove be located on each described Gripper body, and the lower end of described union lever is provided with and the clamping joint snapped in described buckling groove.
Further, described Gripper body also comprises the seed crystal fixture block of the arranged transversely being positioned at described Gripper body lower end.
Further, the vertical section of described seed crystal fixture block is semicircle.
Further, described Gripper body lower end is provided with the clamp groove of clamping seed crystal, and described seed crystal fixture block is located in described clamp groove.
Further, described union lever, described seed chuck and described sleeve are tungsten product or molybdenum product.
Further, described in after clamping seed crystal two, the seed chuck scarp of seed chuck forms the conical surface being positioned at described seed chuck upper end, and the inclined-plane, location in described sleeve is also conical surface, and described in two, the tapering of conical surface is identical.
Further, the upper end of described union lever is provided with the shack be connected with sapphire crystallization furnace stretching structure, and described shack protrudes from the periphery of described union lever.
By such scheme, the utility model at least has the following advantages: structure is simple, only comprise union lever, seed chuck, sleeve three assemblies, solve old-fashioned seed holder adopt binding mode to fix seed crystal brings wastes time and energy, waste the shortcomings such as material, and the internal surface of described sleeve is provided with the inclined-plane, location matched with the seed chuck scarp on described seed chuck outside surface, sleeve relies on gravity by the cooperation on inclined-plane, location and seed chuck scarp, seed chuck to be fastened by seed chuck, have self-locking function, fastening effect is safe and reliable.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technique means of the present utility model, and can be implemented according to the content of specification sheets, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
