Its operating principle is based on atmospheric pressure. Specifically, when the motor is running and pumping air, the valve of the connecting tube is pushed open by atmospheric pressure, allowing gas to enter the cylinder. When inflating an item like a tire, the valve is closed by the air pressure within the cylinder, allowing gas to enter the item. Therefore, air pumps are not only suitable for car tires, but can also be used to inflate a variety of items, including bicycles, balls, and rubber boats.

[0003] However, the traditional high-pressure air pump connecting pipe and the air pump are usually connected by threads, and its air tightness is usually poor. At the same time, the traditional high-pressure air pump is not convenient for restraining the handle, so it is not easy to store and produce.

[0004] The utility model is aimed at improving the above-mentioned problem, and specifically relates to a high-pressure air pump capable of displaying air pressure. Utility Model Content
