[0025] See also Figure 1-2 , the utility model provides a technical solution:

[0026] A simple optical test stand for a video tracheal intubation scope comprises a test plate 2, a positioning plate 3, a video tracheal intubation scope insertion tube 7 and a support plate 8. A copper stud 6 is arranged on the surface of the support plate 8, and a positioning plate 3 is fixed to the top of the copper stud 6 for easy use. A test plate 2 is arranged at the front end of the support plate 8. In order to facilitate distance measurement and positioning, a steel ruler 4 is bonded to the surface of the positioning plate 3. At the same time, a positioning rod 5 connected to the positioning plate 3 is provided on the surface of the positioning plate 3. The video tracheal intubation scope insertion tube 7 is passed through the positioning rod 5 for easy testing. A video tracheal intubation lens end 1 is arranged at one end of the positioning rod 5 close to the test plate 2.

[0027] like Figure 1 As shown:

[0028] The support plate 8 is fixed to the copper stud 6 by screws, and the copper stud 6 is fixed to the positioning plate 3 by screws, so that the three are connected together and have good stability.
