[0002] A microscope is an optical instrument composed of a lens or a combination of several lenses. It is a symbol of mankind's entry into the atomic age. A microscope is an instrument mainly used to magnify tiny objects so that they can be seen by the naked eye. A microscope consists of an eyepiece, an objective lens, a coarse focusing screw, a fine focusing screw, a film clamp, a light aperture, a light shield, a converter, a reflector, a stage, a mirror arm, a lens barrel, a mirror mount, a condenser, and a diaphragm.

[0003] When using the existing stage, the slide needs to be placed on the stage and squeezed and clamped by a slide clamp. However, when the slide is placed, it is easy to cause wear between the slide and the stage, and there is a certain squeezing force between the slide clamp and the stage, which makes it inconvenient to place the slide. Therefore, we propose a microscope stage to solve the above problems. Utility Model Content
