Since the middle part of the microscope turntable 200 is provided with a circular hole, when the microscope turntable 200 is positioned, the plurality of bearings 42 and the limiting ring 43 are sleeved on the outer periphery of the rotating shaft 41, then the microscope turntable 200 is sleeved on the outer periphery of the bearings 42, the pressing piece 45 is installed on the upper end of the rotating shaft 41 through the nut 44, then the lower end of the rotating shaft 41 is screwed on the positioning base 3 through thread cooperation, at this time, the positioning of the microscope turntable 200 on the positioning base 3 is completed, and at this time the microscope turntable 200 can rotate around the rotating shaft 41.
