Abstract: A self-propelling device includes a turning unit and a supporter. The supporter includes a first support sleeve, a second support sleeve and a cover formed respectively cylindrically. A drive wheel is secured to the first support sleeve in a rotatable manner. A pair of follower rollers are secured to the second support sleeve together. The cover is fitted on an outer surface of the second support sleeve externally, and disposed in the turning unit together with the second support sleeve. The turning unit is pressed by the follower rollers to the drive wheel. When the drive wheel rotates, the turning unit is circulated around the second support sleeve in a longitudinal direction of the first support sleeve. An inner wall of a body cavity will not be damaged, as the follower rollers are covered by the cover and do not appear externally even if the turning unit breaks.

Abstract translation: 自推进装置包括转向单元和支撑件。 支撑件包括第一支撑套筒，第二支撑套筒和分别圆柱形地形成的盖子。 驱动轮以可旋转的方式固定到第一支撑套筒。 一对从动辊一起固定到第二支撑套筒上。 外壳上安装有第二支承套筒的外表面，并与第二支撑套筒一起设置在转动单元中。 转向单元被从动辊压到驱动轮上。 当驱动轮旋转时，转动单元沿着第一支撑套筒的纵向方向围绕第二支撑套筒循环。 即使转动单元断裂，体腔的内壁也不会被损坏，因为从动辊被盖子覆盖并且不会出现在外部。
