Description

Technical Field

[0001] This utility model belongs to the field of bottle opener technology, and specifically relates to a bottle opener. Background Technology

[0002] Beer bottle openers are typically made of a thin metal sheet with a notch. This sheet fits over the bottle cap, and by prying it open, the cap is lifted. With various designs, a cylindrical bottle opener has emerged that fits directly over the cap, allowing for easy opening by pressing.

[0003] This cylindrical bottle opener uses a lever principle to pry open the bottle cap with a hook-shaped metal piece. A spring structure then returns the hook-shaped metal piece to its original position for the next use. However, after prolonged use, the spring may become fatigued and its return function may deteriorate, potentially reducing the success rate of opening the bottle cap. Furthermore, the internal structure of this cylindrical bottle opener is sealed, making it impossible to disassemble the internal structure. This can lead to situations where the spring is damaged and cannot be replaced. Utility Model Content

[0004] The purpose of this invention is to provide a bottle opener to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottle opener, comprising a cylindrical outer shell, an inner sleeve that is telescopically movably disposed inside the cylindrical outer shell via a limiting movable component, a limiting anti-disengagement sleeve connected to the bottom end of the cylindrical outer shell to prevent the inner sleeve from detaching from the cylindrical outer shell, a lifting component disposed at the top of the inner sleeve, a resisting block for squeezing the lifting component disposed inside the cylindrical outer shell, an extension seat disposed on the inner edge of the inner sleeve, an installation groove disposed inside the extension seat, a metal connecting rod movably disposed within the installation groove, the top end of the metal connecting rod extending to the outer side of the top of the inner sleeve, and the metal connecting rod being able to move up and down via the lifting component, a bottle opening hook disposed at the bottom end of the metal connecting rod, and the bottle opening hook extending to the outer side of the extension seat, an operating port aligned with the installation groove disposed on the extension seat, a metal connecting rod disposed between the operating port and the metal connecting rod, and in the natural state, the metal connecting rod being kept vertical by a return spring A, and a closing protrusion for gradually narrowing the opening disposed inside the inner sleeve.

[0006] Preferably, the limiting movable component includes multiple limiting sliding protrusions disposed on the outer side of the telescopic inner sleeve, and multiple limiting sliding grooves disposed on the bottom edge of the cylindrical outer shell, wherein the limiting sliding protrusions extend into the corresponding limiting sliding grooves for limiting sliding.

[0007] Preferably, the limiting anti-detachment sleeve is connected to the bottom of the cylindrical outer shell by threads, and the minimum inner diameter of the limiting anti-detachment sleeve is consistent with the inner diameter of the cylindrical outer shell.

[0008] Preferably, the lifting assembly includes a bearing seat disposed on the top of the telescopic inner sleeve, and a pressing lever located on the bearing seat. The pressing lever is rotatably disposed on the bearing seat via a connecting shaft. A return spring B for resetting the pressing lever is also connected between the bearing seat and the pressing lever. One end of the pressing lever is kept in contact with the resisting block through the return spring B.
