The working surface of the sight mark 16 is perpendicular to the optical axis of the illumination light source 29; the coupling tube 28 is connected with the sight mark film box 15 on the left and right sides by a thread, and the eyepiece tube 17 is installed on the left and right sides of the sight mark film box 15, and the two are connected by a thread; a window is opened on the eyepiece tube 17, and the plane formed by the window forms an angle of 45° with the same optical axis of the illumination light source 29; on the upper corner window of the eyepiece tube 17, a semi-reflective semi-transparent reflector structure is installed, and the semi-reflective semi-transparent reflector structure is composed of a semi-reflective semi-transparent reflector seat 18, a semi-reflective semi-transparent reflector 19, a camera rotating baffle 20, a small camera 21, a semi-reflective semi-transparent reflector revolving door camera fixed small shaft 26, and a semi-reflective semi-transparent reflector revolving door camera fixed seat 27.The semi-reflective mirror seat 18 on the semi-reflective and semi-transmissive reflecting structure is fixed on the upper corner window of the eyepiece arm 17 with screws, a semi-reflective mirror 19 is installed at the bottom of the semi-reflective and semi-transmissive mirror seat 18, the mirror surface of the semi-reflective and semi-transmissive mirror 19 faces the left and right light sources, and a semi-reflective and semi-transmissive mirror revolving door camera fixing seat 27 is installed on the upper part of the semi-reflective and semi-transmissive mirror seat 19, and the two are connected by the semi-reflective and semi-transmissive mirror revolving door camera small shaft 26 at the lower part of the left and right sides; the rotating baffle plate in front of the small camera 21 is fixed to the front end of the semi-reflective and semi-transmissive mirror revolving door camera fixing seat 27 with a nail shaft, so that it can rotate flexibly; at the bottom of the eyepiece barrel 17, a semi-reflective and semi-transmissive mirror 19 is installed. At the end, an eyepiece gluing group 25 is installed by a thread, and the focus of the eyepiece gluing group falls on the sight mark 16; on the semi-reflective and semi-transparent mirror revolving door camera fixing seat 27, the camera fixing pressure plate 22 uses screws to press the small camera 21 firmly, and the head of the small camera 21 faces the semi-reflective and semi-transparent mirror 19 and points to the eyepiece gluing group 25. The optical axis of the optical system formed by the camera rotating baffle 20, the small camera 21, the semi-reflective and semi-transparent mirror 19 and the eyepiece gluing group 25 is perpendicular to the common optical axis of the illumination light source 29; it is symmetrical with the maxillary support 23 as the center, and is symmetrically distributed relative to the front palatal support 23 in the left and right optical systems.

[0014] The illumination light source 29 in this embodiment adopts LED light source, which is welded on the light source circuit board 30. The light source circuit board 30 is fixedly connected with the light source circuit board fixing seat 31 by screws. The illumination light source 29 should be installed accordingly so that the optical axes of the two illumination light sources overlap and are on the same optical axis; the material of the connecting tube 28, the sight mark film box 15, and the eyepiece tube 17 adopts aluminum alloy ZL24 (aluminum alloy developed by Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences), the outer surface is sprayed with gray electrostatic paint, and the inner surface is sprayed with black matte paint; the semi-reflective mirror 19 is processed by Kg optical glass. The surface of the semi-reflective mirror 19 is plated with silicon oxide dielectric film and zirconium oxide dielectric film, and the transmittance and reflectivity are 50% respectively. The angle between the left and right semi-reflective mirrors 19 is 90°, which are perpendicular to each other. The left and right semi-reflective mirrors 19 and the common optical axis of the left and right illumination light sources 29 form an angle of 45°. The small camera 21 adopts the Kangli camera produced by Shenzhen Kangli Technology Co., Ltd. The resolution of the small camera 21 is 580 lines.

The structure is symmetrical with the upper jaw support 23 as the center, and the left and right optical systems are symmetrically distributed with the upper jaw support 23 as the center.

[0015] Working principle: The optical axis of the optical system of the illumination light source 29 forms an angle of 45° with the semi-reflective mirror 19, and the optical axis passes through the center of the semi-reflective mirror 19. Because the illumination light sources 29 are installed relatively, the optical axes of the optical systems of the left and right illumination light sources 29 coincide with each other on the same optical axis, so the light reflected from the semi-reflective mirror 19 is perpendicular to the common optical axis of the illumination light source 29. From the optical system formed by the left and right small cameras and the left and right eyepieces (eyepiece glue assembly 25), the optical axis of the optical system formed by the camera rotating baffle 20, the small camera 21, the semi-reflective mirror 19 and the eyepiece glue assembly 25 is also perpendicular to the common optical axis of the illumination light source 29, and the optical axis of the optical system passes through the center of the semi-reflective mirror 19, that is, the optical axis of the optical system formed by the camera rotating baffle 20, the small camera 21 and the eyepiece glue assembly 25 coincides with the optical axis of the light reflected from the illumination light source 29 by the semi-reflective mirror 19 on the same optical axis. In this way, when the illumination light source 29 is illuminating, the light is directly reflected to the eyepiece bonding group 25 through the semi-reflective and semi-transparent reflector 19, illuminating the field of view of the eyepiece bonding group 25, and focusing on the patient's condition through the eyepiece bonding group 25. When the rotating camera rotating baffle 20 leaves the field of view, it can be photographed in real time by the small camera 21 aimed at the bonding group 25, thereby achieving the purpose of the mechanism being able to process the nine eye positions of the patient's eyes in real time.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
