Zusammenfassung:	A suction device includes an elastic base and a release structure connected operably to the elastic base. The elastic base has a peripheral portion for to hermetically contacting a contact surface and defining a vacuum chamber therebetween when a predetermined external force is applied on the elastic base, thereby mounting the elastic base on the contact surface. The release structure has a projection protruding outwardly and partially from the elastic base when an applied force on the elastic base is greater than the predetermined external force and retracting inwardly within the elastic base so as to be disposed in the vacuum chamber when the elastic base is mounted on the contact surface such that a distance between the projection and the contact surface is greater than zero.
