After cutting off the bottle seal, wipe the bottle mouth clean with a cloth or paper towel, then insert the auger tip of the corkscrew into the center of the cork (if the cork is drilled crookedly, the cork will easily be broken), and slowly rotate in a clockwise direction To drill into the cork, if you use a butterfly-type corkscrew, when you turn the screwdriver, the handles on both sides will also rise slowly. When the handles rise to the top, just gently pull them down The cork can be pulled out (but if the cork is too long, it can be difficult to pull it out all at once).

Butterfly bottle opener:

1. Place the paper cutter on the top of the wine bottle, hold the bottle mouth with the blade, and turn 90 degrees to cut the protective paper;

2. Insert the bottle-opening needle into the wine bottle from the middle of the cork, and protect the bottle mouth with a plastic protective sleeve;

3. Inject air into the bottle by moving up and down until the cork slides out from the bottle mouth (usually 4-7 times per bottle can be opened);

4. Use the small plastic slider on the protective sleeve to withdraw the cork from the gas needle.

The double-arm lever-type bottle opener, also known as the butterfly-type bottle opener, consists of two liftable arms and an auger bit. It is labor-saving and effective, but not easy to operate, large in size, inconvenient to carry, and only suitable for home use. As the drill bit drills into the cork, its arms also rise upwards, and when it is lifted to the end, it is only necessary to press the arms and the wine cork is pulled out.

There are many kinds of bottle openers, so the principles are almost the same, and there is not much difference, so as long as you are familiar with one of them, you can change it to the other. You can understand it after a while, but pay attention to the possibility of cut off.
