Since the valve plug 8 is touched by the air core center pin 94 of the air nozzle 9, the valve plug 8 moves to the right to compress the spring 51 causes the blocking ring 86 to leave the oblique tapered wall 522 of the top post lock 52 that originally blocked the contact. The hollow space 520 of the top post lock 52 forms a circulated passage state. At this time, the chemical glue pushed by the air can pass through The passage 73 of the base 7 enters the cylindrical chamber 70, and then passes through the circulation groove 83 of the expanded end 82 outside the valve plug 8 and continues to pass through the circulation groove of the valve plug 8 in the hollow chamber 520 of the top column lock 52 85. The circulation port 540 and the screw hole 61 of the top contact pad 54 and finally enter the broken tire through the circulation hole 922 of the front seat 92 in the air nozzle 9, the hollow sleeve 93 and the valve seat 932 of the hollow sleeve 93 In this way, the rubber can be filled into the tire 99 to repair the tire. Of course, the compressed air can continue to enter the flat tire 99 for inflation until the normal tire pressure.

In summary, this creation is to provide a blowout prevention structure that combines a car tire 99 air nozzle 9 with an air compressor hose connector, which prevents the user from violating the chemical glue caused by incorrect operation steps. The lack of injection is also very progressive, which obviously meets the requirements of a creative patent.
