The roller moves to contact the bottom surface of the push plate and continues to press the push plate. At this time, the push plate rotates with the Z-shaped frame. The rotation of the push plate presses the rotating wheel and the fixed plate to move. At this time, the fixed plate moves with the rice-shaped disc and the inflation valve to slide on the surface of the base telescopic rod. At this time, the first spring is stretched.

[0018] 3) The vehicle hydrogen exchange station for quickly replacing hydrogen tank is used. The fixed valve and the inflation valve are connected by moving towards each other. The inflation valve presses the ring seat to move, and the sliding ring moves on the surface of the fixed valve. With the mutual movement of the fixed valve and the inflation valve, the hemispherical groove contacts and presses the ball head.
