[0034] The operating steps of the utility model are:

[0035] When the device is in use, the threaded tube 2 can be used to install and connect with the device to be inflated. When inflating the device, the user can pull the pull rod 24 upwards and use the fixing plate 20 and the connecting rod 21 to drive the two plug blocks 18 to move closer to each other so that the plug blocks 18 are separated from the slots 17.

At this time, the inflation nozzle in the inflation device squeezes the push rod 8 so that the sealing disk 13 is separated from the sealing ring 5 to open the valve body 1, and then inflation can be carried out. After the inflation nozzle of the inflation device is separated from the air inlet pipe 3, the return spring 10 pushes the connecting plate 12 and the sealing plate 13 upward so that the sealing plate 13 contacts the sealing ring 5 again to seal the valve body 1, and then the user can pull the pull rod 24 upward to retract the plug 18 into the dust cover 4. At this time, the user inserts the dust cover 4 into the air inlet pipe 3, and when the plug 18 corresponds to the slot 17, the pull rod 24 is released, and the elastic force of the spring 23 is used to push the fixing plate 20 downward, so that the two plugs 18 are inserted into the slot 17 away from each other to fix the dust cover 4;

[0036] When it is necessary to release the pressure on the inflatable device, the user can press the push rod 8 downward so that the sealing disk 13 drives the slider 14 to slide downward. After the sealing disk 13 separates from the sealing ring 5, the gas in the inflatable device is discharged. When the slider 14 slides to the bottom of the slide groove 15, it enters the annular limit groove 16. At this time, the user can rotate the push rod 8 so that the sealing disk 13 drives the slider 14 to rotate into the annular limit groove 16, so that the sealing disk 13 is always separated from the sealing ring 5 for pressure relief and release.
