The position distance between the second bearing seat 113 relative to the first bearing seat 111 or the detection platform 131 can be adjusted and arranged according to the needs of the user.
[0029] In the present embodiment, the second bearing seat 113 can provide a structure for supporting the bottom side of the scope tube 22. After the handle 21 and the scope tube 22 are supported at the same time, the overall endoscope instrument 2 can be maintained in a horizontal state.

[0034] Further, the detection platform 131 has a backlight source 1311 and a detection table 1312. The backlight source 1311 is arranged below the detection table 1312. The backlight source 1311 emits light towards the detection table 1312. In this way, the lens end 221 of the scope tube 22 of the endoscope 2 is placed on the detection table 1312.
