AI Technical Summary
When observing slides, existing microscopes lack an angle rotation device, which makes it difficult to adjust the angle of the slides, which requires manual adjustment, and it is difficult to accurately control the rotation angle, which wastes time finding the original observation position.
A microscope rotation and cutting observation device is designed, including setting an inner cylinder, an outer cylinder and a rotating cap on the stage. The bottom of the inner cylinder is surrounded by a gear rail, and a shrapnel is provided with a shrapnel in the inner side wall of the outer cylinder. The rotating cap drives the inner cylinder to rotate. The shrapnel moves on the gear rail and rubs to emit a prompt sound, and cooperates with the angle mark to achieve accurate angle adjustment of the slide.
It realizes convenient and precise rotation observation of microscope slides. Instead of manual rotation, it can quickly understand the rotation angle and prevent the inner cylinder from rotating relative to the outer cylinder without external force, improving observation efficiency and angle control accuracy.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of microscopes, in particular to a microscope cutting observation device. Background Art
[0002] Microscopes are instruments that are mainly used to magnify tiny objects so that they can be seen by the naked eye, such as in the field of environmental protection, where pollution sources are observed in minute detail. Microscopes magnify objects on the glass slide on the stage. In order to ensure that the position of the glass slide is fixed during observation, it is necessary to fix it with a slide clamp to ensure that the specimen is facing the hole. To adjust the position of the glass slide, the observer often needs to manually adjust the glass slide or control the stage movement. However, there is a lack of an angle rotation device, and manual adjustment is often required. Due to magnified observation, it is difficult to determine the original observation position after the angle is offset, and it takes a lot of time to find it. In addition, it is difficult to control the rotation angle. Therefore, it is necessary to design a microscope rotation observation device that can accurately and conveniently adjust the rotation of the glass slide, instead of directly rotating the glass slide manually, while being able to accurately control the adjustment angle.
