New description: [New technical field] This creation relates to the technical field of grinders for grinding fine-edged blades, in particular to a rotary-positioned grinder seat. [Prior Art] It is known that a drill used in a drilling operation for a printed circuit board has a drill blade diameter of only about 0.1 to 1.0 mm. Such a drill is commonly known in the industry as a micro drill. Since the drill bit of the micro drill bit needs to be ground again after using it for a period of time, it can restore the precision of the drilling and prolong its service life; however, the grinding machine will wear out during the grinding of the cutting edge, resulting in the grinding machine and The spacing of the drill changes, which causes the grinding machine to gradually lose the precision of the grinding edge grinding. Therefore, the angle adjustment of the grinding machine is required. Moreover, when the grinding machine wear condition is too serious, the grinding machine needs to be performed. replace. At present, when the grinder is angle-adjusted, repaired, and replaced, it is often inconvenient due to the obstruction of other adjacent components. Therefore, it is desirable to provide a device technology that facilitates angular adjustment, repair, and replacement of the grinder to solve the problems of the prior art described above.
