A visual adjustment assembly is designed, including a main cylinder, eyepiece connector and drive ring. Through the coordination of guide screws and spiral holes, the eyepiece can only move linearly along the optical axis of the optical path system.
During the visual degree adjustment process, it is realized that the eyepiece only moves linearly along the optical axis of the optical path system, thereby improving the observation effect and accuracy of the microscope device.

A diopter adjustment mechanism is provided between the eyepiece and the connecting tube of the main microscope. When the traditional diopter adjustment mechanism is performing diopter adjustment, the eyepiece not only needs to move in a straight line, but also needs to rotate around the optical axis of the optical path system, which will cause the optical axis of the eyepiece to deviate from the optical axis of the optical path system. This phenomenon affects the observation effect and accuracy of the microscope. Therefore, a stereo microscope is needed that ensures that the eyepiece only moves in a straight line along the optical axis of the optical path system when performing diopter adjustment.

[0013] 1. When the utility model is in use, the user rotates the manual ring to drive the driving ring to rotate synchronously on the outer ring wall of the second connecting part on the main tube, and the spiral hole of the driving ring drives the guide screw to move up and down within the height range of the strip hole, thereby driving the eyepiece tube and the eyepiece to move up and down together; the user can adjust the distance between the eyepiece and the microscope host through the diopter adjustment component according to his or her own vision to obtain a clearer image. The utility model can ensure that the eyepiece can complete the diopter adjustment by only moving linearly along the optical axis of the optical path system.
[0014] 2. The eyepiece and the eyepiece tube are connected by plug-in, which is convenient for replacing eyepieces with different magnifications; the pressure ring limits the driving ring to prevent the driving ring from moving up and down, and allows it to rotate flexibly on the outer ring wall of the second connecting part.
