Abstract
A suction device includes a sucking member having a connecting body connected integrally to a flexible disc body that is disposed under an upright sleeve, a connecting member disposed in the sleeve and connected to the connecting body, and an operating rod connected pivotally to a pivot block unit on the sleeve and to the connecting member. The operating rod is operable so that an assembly of the connecting member and the connecting body is pulled upwardly, thereby forming a vacant space between a central portion of the disc body and a supporting surface to which a peripheral portion of the disc body is attached sealingly.
