The mounting base 1 has a rotating groove 3 at its upper end, within which a circular plate 4 is rotatably mounted. A limit component 5 is mounted at one end of the mounting base 1, and one end of the limit component 5 is connected to the circular plate 4. A first telescopic rod 6 is mounted in a circular array on the upper end of the circular plate 4. The automatic polarimeter body 2 is fixedly mounted on the free end of the first telescopic rod 6. A lifting component 7 is mounted in the middle of the circular plate 4, and one end of the lifting component 7 is connected to the automatic polarimeter body 2. A control panel 8 is fixedly mounted at one end of the mounting base 1. During use, the lifting component 7 is first activated via the control panel 8. Component 7 automatically moves the automatic polarimeter body 2 to a suitable height, eliminating the need for manual adjustment by staff. This is convenient, quick, and saves time and effort. At this time, the first telescopic rod 6 extends and retracts accordingly, guiding and limiting the automatic polarimeter body 2. When it is necessary to adjust the installation angle of the automatic polarimeter body 2, first manually rotate the circular plate 4 in the rotating groove 3 to adjust the automatic polarimeter body 2 to a suitable angle. Then, the limiting component 5 limits the circular plate 4, thereby fixing the automatic polarimeter body 2, making it convenient for users to observe the test results. Then, the concentration, content, and purity of the substance are analyzed by measuring the rotation angle of the polarization vibration plane of the substance through the automatic polarimeter body 2.

[0023] like Figure 3 and Figure 4 As shown, the limiting component 5 includes a T-shaped plate 501, a damping telescopic rod 502, and a spring 503.

One end of the damping telescopic rod 502 is fixedly installed in the circular groove 504, and the free end of the damping telescopic rod 502 is fixedly connected to the T-shaped plate 501. The spring 503 is sleeved on the outside of the damping telescopic rod 502, with one end fixedly installed in the circular groove 504 and the other end fixedly connected to the T-shaped plate 501. Limiting grooves 505 are formed in a circumferential array on the outer side of the circular plate 4. The T-shaped plate 501... One end extends into the limiting groove 505. When in use, first manually move the T-shaped plate 501 outward. At this time, the damping telescopic rod 502 extends, the spring 503 is stretched, and one end of the T-shaped plate 501 is disengaged from the limiting groove 505. Then manually rotate the circular plate 4 in the rotating groove 3 to adjust the automatic polarimeter body 2 to a suitable angle. After that, release the T-shaped plate 501. Under the action of the deformation force of the spring 503, the T-shaped plate 501 automatically resets, so that one end moves into the limiting groove 505 to fix the circular plate 4, thereby fixing the automatic polarimeter body 2.

[0024] like Figure 5As shown, the lifting assembly 7 includes a servo motor 701 and a circular plate 702.
