[0002] In the prior art, in the process of rock and mineral analysis and identification, rock or coal sample slices are usually involved. Rock or coal sample slices refer to rock or transparent mineral specimens used for observation and research under a polarizing microscope, because they are relatively small, about 0.03 mm thick, and about 2 cm in diameter.
[0003] In addition, the oriented thin sections of rock or coal samples cut by rock group analysis are generally required to be perpendicular to the b-axis of the rock group axis, or perpendicular to the strike of the foliation, or perpendicular to the strike of the fault plane. In principle, the direction of the thin section is selected according to the needs of the problem being studied. In the field environment, it is even more difficult to effectively find the cutting direction. In addition, the accuracy of the results of rock group analysis and microstructural oriented analysis also depends to a large extent on the preparation of oriented thin sections. Therefore, how to design a positioning device to restore it to its original state and facilitate the calibration and preparation of oriented thin sections is a technical problem that needs to be solved urgently.

The specimen inclination positioning device is sleeved on the screw rod inside the specimen orientation positioning device. Two oppositely arranged fixing rods are axially arranged inside the specimen inclination positioning device. The fixing rods are also connected to fixing claws through springs, and the axial direction of the fixing rods is perpendicular to the axial direction of the screw rod.

[0032] like Figure 1 and Figure 5 As shown, three retractable nuts 8 are vertically arranged at the bottom of the specimen orientation positioning device body 3, and a retractable bolt 9 is arranged at the bottom of the retractable nut 8. The retractable nut 8 and the retractable bolt 9 constitute a height adjustment device. Figure 1 and Figure 6 As shown, a level bubble 10 is provided on the specimen orientation positioning device body 3 for leveling, and the level bubble 10 is provided on the outer side of the specimen orientation positioning device body 3 .
