本发明技术方案的手柄组件10的壳体11形成有空腔，用于放置摆杆12、底座13和摆轴14；底座13固定于壳体11，固定方式可为卡设、螺接等。使用者操作摇杆16，带动摆杆12变换角度，进而带动牵引线15产生位移，使得蛇骨段22发生弯曲或转向，从而使摄像头组件30变换位置，以到达检测部位。
所述手柄组件10还包括摆轴限位圈17a和弹性件17b，所述弹性件17b容纳于所述摆杆12，所述摆轴限位圈17a盖设于所述摆杆12，所述第一端141穿设所述摆轴限位圈17a，并通过所述弹性件17b抵持于所述摆杆12。
本发明技术方案第二端142与摆杆12连接，第一端141弹性抵持于底座13，用于定位摆杆12的摆动角度。当操作摇杆16时，第二端142随之一起摆动，第一端141在底座13中受力被挤压，当摇杆16不受操控时，第一端141被底座13的弹性挤压力固定，使得摇杆16的角度和方位固定。相应地，底座13开设有容置孔，弹性件17b容纳于该容置孔中，摆轴限位圈17a套设于第一端141，并盖设于底座13，从而将弹性件17b和第一端141限位在底座13和摆轴限位圈17a之间。摆轴限位圈17a和底座13的固定方式可采用螺接等方式。
第一端141抵持在弹性件17b上，第一端141与摆轴限位圈17a之间的摩擦力用于保持摆轴14的位置，即保持摆杆12的位置。摆轴限位圈17a、弹性件17b与第一端141接触的面均设置为匹配的球面，以便操控摇杆16时，第一端141的位置容易发生变化。
所述摆杆12的端部设有至少一摆臂，每一摆臂连接一牵引线15，所述牵引线15贯穿所述底座13和插入管组件20，而连接于所述摄像头组件30。
本发明技术方案中摆杆12形成有多个摆臂，优选为4个，每一摆臂连接有牵引线15，带动蛇骨段22发生弯折或转向，进而控制摄像头组件30的不同位置。
所述手柄组件10还包括至少一弹簧管，每一弹簧管套设于一牵引线15外部。
本发明技术方案的每一牵引线15外套设有弹簧管，当牵引线15控制插入管组件20弯曲时，弹簧管使得弯曲处受力均匀，避免插入管组件20被磨损，此外，弹簧管能有效避免多根牵引线15之间发生缠结。
所述工业内窥镜100还包括连接于所述底座13远离摇杆一侧的安装部18、LED灯70和照明光缆80，所述LED灯容纳于所述底座和所述安装部18围成的空腔，所述安装部18还形成有与所述空腔连通的通孔，所述照明光缆80贯穿所述通孔和所述插入管组件20，连接于所述摄像头组件30。
本发明技术方案的安装部18用于固定LED灯70和照明光缆80。
所述插入管组件20包括耐磨管21和连接于所述耐磨管21的蛇骨段22，所述耐磨管21连接于所述手柄组件10，所述蛇骨段22连接于所述摄像头组件30。
插入管组件20还套设有一层钨丝网及防水膜，钨丝网用于保护插入管组件20，避免其磨损，防水膜能够防止水分进入插入管组件20内部，而影响照明光缆80和信号传输线缆的工作状态。蛇骨段22前端还设有固定件，用于固定连接摄像头组件30。
本发明技术方案的蛇骨段22的弯曲半径小，通过该蛇骨段22控制摄像头组件30的方向和角度，便于进行检测，插入管组件20还包括耐磨管21，该耐磨管21的弯曲半径大，用于将摄像头组件30送至待测部位。
进一步地，该蛇骨段22由若干关节环连接形成，根据待测对象的弯曲程度，可设计蛇骨段22的关节环的数目。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
