Abstract
A suction device includes a suction head, a fixing assembly, a rotating assembly, and a sliding assembly. The rotating assembly includes a shaft defining a spiral sliding slot. The suction head is attached to an end of the shaft. The sliding assembly is slidable and attached to the fixing assembly and includes a guiding post. An end of the guiding post is slidable and received in the spiral sliding slot. The sliding assembly is able to slide relative to the fixing assembly to slide the guiding post along the spiral sliding slot, thereby urging the shaft together with the suction head to rotate.
