The cylinder body defines a cavity and a first air hole, and the first air hole is in communication with the cavity. The variable-volume body is arranged within the cavity. The variable-volume body is configured such that, through a change in a volume of the variable-volume body within the cavity from large to small, an air pressure within the cavity is reduced, for providing a suction force externally through the first air hole.
