Abstract
The rotary suction device includes a suction disk, a middle cover, and an upper cover. The suction disk includes a base and a soft disk. The base includes a peripheral wall, a guide block, an inclined surface, and a central circular trough. The middle cover includes a central through hole around the peripheral wall and a guide trough. The guide trough is around the guide block, and the middle cover is capable of axial displacement relative to the suction disk. The upper cover includes a central pivot, a sliding block, and an elastic component. The central pivot is accommodated in the central circular trough such that the upper cover is capable of rotating relative to the suction disk. The elastic component is disposed between the upper cover and the suction disk. The sliding block is forced to against the inclined surface by the elastic force of the elastic component.
