When in use, the locking block 102b at the end of the first inner tube 102a is inserted into the slot 202d of the second outer tube 201, and then rotated to a certain angle when reaching the end, so that the first inner tube 102a is connected and fixed with the second outer tube 201. In the process, the boss 103a is inserted into the rotary groove 202a-1 in the second inner tube 202a, the thimble 103b pushes the valve core 202b open, and the gas flows in the direction from the first vent hole 103a-1, enters the rotary groove 202a-1, then enters the transition groove 202a-2, then enters the valve core 202b from the transition groove 202a-2 through the second vent hole 202b-1 on the valve core 202b, and finally reaches the interior of the device to be inflated from the interior of the valve core 202 b. Meanwhile, when the valve core 202b is pushed open, the third vent port 202b-2 at the middle part thereof is just aligned with the branch port 203a on the second inner pipe 202 a. A portion of the gas enters the diversion channel 203b from the diversion port 203 a. Because the air pressure inside the inflated device is gradually increased in the inflating process, the air pressure inside the diversion channel 203b is also gradually increased, so that the air pushes the pressure bearing plate 203c to move, the first push rod 203d enables the second push rod 203f to move downwards, the locking block 102b is further extruded to move leftwards according to the direction shown in the figure, the first inner tube 102a is pulled to move towards the second inner tube 202a, and the first inner tube 102a and the second inner tube 202a are tightly connected to each other to prevent air leakage.
