Small-diameter direct and side view electric rotary focusing endoscope

The invention discloses a small-diameter direct and side view electric rotary focusing endoscope which comprises a control section and a working section rotationally connected with the control section. The control section comprises a circuit cabin and a PCB (Printed Circuit Board) arranged in the circuit cabin, and the outer end of the circuit cabin is connected with an external power supply through a connector; the working section comprises a rotation control assembly rotationally connected with the circuit cabin, and a side view assembly and a direct view assembly which are sequentially connected with the rotation control assembly. Automatic rotation of the endoscope is achieved, the front side and the side wall of a pipeline can be shot at the same time, the endoscope can better adapt to the dark environment, and the structure of the supporting device can be simplified when the endoscope is used. 本发明公开了一种小直径直侧视电动旋转对焦内窥镜，包括控制区段和与所述控制区段转动连接的工作区段；所述控制区段包括电路舱和设置在所述电路舱内的PCB电路板，所述电路舱的外端通过接插件与外部电源连接；所述工作区段包括与所述电路
