Background

With the increasing level of living at present, the demands of the public on the quality of life are also increasing. Many people can match a cup of wine after working or during dining to promote appetite, relax mind and body and improve life interest, and wine is the first choice of wine tasters.

The wine with good quality is stored in the cellar for a period of time, and then is packaged into a bottle and sold in the market. In order to keep the wine in the bottle to be fermented, in most cases, a cork is plugged into the bottle mouth, and wine can be slowly fermented in the bottle by using the cork, so that a taster can obtain better wine aroma and taste when tasting the wine.

However, in the case of wine bottles with cork on the market, the cork cannot be removed by hand, and only a bottle opener is needed to remove the cork from the bottle. The conventional bottle opener is mostly provided with a grab handle, a spiral downward corkscrew is arranged at the central vertical grab handle, and the lowest end of the corkscrew is sharp so as to drill the corkscrew into a cork by rotating the grab handle. However, because cork blocks are typically tight-packed at the finish, many low-strength users are unable to remove the cork block from the finish after drilling a corking drill into the cork block; if force is forced, wine is easily leaked after the cork block is forced to be taken out because of the instability of holding the wine bottle, so that wine collected for many years is wasted, and the use is inconvenient.

Bottle openers have been developed that use a plunger to remove the cork block from the bottle. The bottle opener is provided with a cylindrical main body, one end of the main body is an open end, the other end of the main body is a closed end, a perforation is formed in the closed end, a stirring rod with parallel concave-convex lines is arranged in the perforation, one end of the stirring rod is arranged in the main body and is a spiral corkscrew, the other end of the stirring rod is a rotary grab handle, two pressing rods are arranged on two sides of the perforation of the main body, the end part of the pressing rod, which is connected with the main body, is in a gear shape, the gear-shaped part can be matched with the concave-convex lines of the stirring rod, and the gear on the pressing rod can drive the concave-convex lines on the stirring rod by utilizing the up-down driving rotation of the pressing rods, so that the stirring rod moves up and down. When the cork stopper is used, the spiral cork stopper is placed on the cork stopper, the rotary grab handle is rotated by hand to enable the cork stopper to be drilled into the cork stopper, and then the pressing rod is pressed downwards to enable the stirring rod to move upwards, so that the cork stopper is driven to leave the bottle mouth.

However, when the bottle opener is used, although labor can be saved and the cork block is not required to be pulled out of the bottle opening by force, the gear-shaped part connected with the stirring rod on the pressing rod and the pressing rod are of an integrated structure, and when the stirring rod is acted, the corkscrew continuously drills into the cork, the gear-shaped part of the pressing rod is matched with concave-convex lines of the stirring rod, so that the action between the pressing rod and the stirring rod is absolute linkage, and the pressing rod is continuously turned upwards under the drive of the acting force, so that certain inconvenience is brought to users; meanwhile, when the bottle opener has some faults and needs to be maintained and repaired daily, the inconvenience of checking and repairing is also caused due to the action linkage between the pressing rod and the stirring rod.
