It is difficult for many people to open the plastic bottle cap or the jam jar cap. So we designed a bottle opener, using the principle of gear transmission principle and sharp contact surface can increase the friction. It can open the bottle cap which is difficult to open, and can adjust the size of the bottle opening structure, which is suitable for all the size of the common bottle cap.
