The invention discloses a novel cup cover. The cup cover comprises a cover body I, a cover body II and a caliber adjusting mechanism, the cover body I and the cover body II are stacked vertically andcan rotate relative to each other, and the caliber adjusting mechanism comprises connecting rods I, connecting rods II and rubber balls; one end of each connecting rod I is connected with the inner wall of the cover body I, the other end of each connecting rod I is connected with the corresponding rubber ball, one end of each connecting rod II is connected with the inner wall of the cover body II,and the other end of each connecting rod II is connected with the corresponding rubber ball. The connecting rods I are hinged to the connecting rods II, the rubber balls are wrapped on the peripheries of the junctions between the connecting rods I and the connecting rods II, the ends, connected with the inner wall of the cover body I, of the connecting rods I are moved along with the rotation ofthe cover body I, and the ends, connected with the inner wall of the cover body II, of the connecting rods II are moved along with the rotation of the cover body II. When the cover body I and the cover body II are rotated in opposite directions, the connecting rods I and the connecting rods II get close to each other, the rubber balls are pushed toward the middle, that is to say that the rubber balls are moved in the direction close to a cup body, and thus the cup cover can be applied to containers of different calibers. The invention also provides a using method of the novel cup cover.
