  • Publication number: 20220315405
    Abstract: A bottle opener, comprising a cover, an inflating device, and a shell sleeved outside the inflating device. A valve plug assembly comprises a valve plug base, a valve plug, and a valve plug stopper. The outer wall of the rear end of an inner inflating tube is sleeved with a piston ring, and the outer wall of the top end thereof is sleeved with a stop component. The inner inflating tube is provided with a first through hole. An inflating needle passes through the first through hole and is fixed in the through hole. The cover is connected to the shell. This device opens a wooden cork by means of air pressure, thereby effectively protecting the integrity of the wooden cork and improves the tightness of the wooden cork during repeated use. The bottle opener is convenient to carry, avoids scratching, and achieves a protection effect.
