When the two joint bodies are connected, the ejector rod at the front end of the one-way valve core collides, forcing the valve core to retreat and compress the spring to open the passage.

The connection of the two joint bodies uses 6 (or 8) steel balls on the joint body to fall into the v-shaped groove of the joint body. When working, the steel balls are pressed by the outer sleeve and cannot exit. The outer sleeve is The spring resists and remains at the right end position.
