The clamping rod 11 is provided with two groups, and the two groups of clamping rods 11 are elastically connected by a spring 12. The clamping rod 11 is squeezed by the spring 12 to keep the sliding out state, and the lower part of the clamping rod 11 is slidably connected to the inside of the side end of the positioning groove 2, and the two ends of the spring 12 are respectively fixedly connected to the two groups of clamping rods. The middle side of the connecting rod 11 is squeezed to make the clamping rod 11 slide into the inside of the connecting rod 14, and the connecting rod 14 can be quickly slid to drive the sliding assembly to quickly slide up and down to adjust the air pressure, thereby reducing the insecurity of the overall device.

The screw 3 drives the lower piston plate 8 and the block 9 to slide until the air pressure returns to a suitable range, and then the sliding handle 13 is released. At this time, the spring 12 squeezes the clamping rods 11 at both ends and the sliding handle 13 to slide to both ends. The clamping rod 11 slides into the positioning groove 2 to fix the piston plate 8 and no longer slide. At this time, the lifting device 10 can be used to drive the screw 3 to slide up and down to adjust the air pressure. When the air intake pipe 4 needs to be removed, the air intake pipe 4 can be slid up. At this time, the sliding sleeve 15 slides up under the pull of the spring 2 16 until the lower end is restricted by the water tank 6 and cannot slide.
