Referring to FIG. 4A and FIG. 4B, FIG. 4A is a cross-sectional view of a nozzle of a preferred embodiment of the present invention, and FIG. 4B is a cross-sectional view of the reversing dual-purpose nozzle of the present invention. The embodiment connects a cross-sectional view of an American nozzle. As shown in FIG. 4A, when the reversing dual-purpose nozzle of the embodiment is connected to the French air nozzle P, that is, in both directions The second internal thread 221 of the French joint end 22 of the joint 2 is screwed to the external thread P of the French air nozzle P. Accordingly, when inflating, the inflated airflow flows from the air source (such as an inflator, not shown) through the air passage 43, the central air passage 31, and the through passage 23 and opens the French valve Pv to enter the French air nozzle P. And tires (not shown).

In addition, as shown in FIG. 4B, when the reversing air nozzle of the present embodiment is connected to the American air nozzle S, the first internal thread 211 of the female joint end 21 of the bidirectional joint 2 is screwed. Thread Ss outside the American nozzle S. At this time, as shown in the figure, the American valve Sv of the American air nozzle S has been opened by the inner top member 213. That is, after the American joint end 21 of the two-way joint 2 is connected to the American air nozzle S, the American valve Sv is opened, and the inflated air flow can also flow from the air pressure source through the air passage 43, the central air passage 31 and the through passage 23 to enter the American gas. The mouth S; in addition, because the American valve Sv is in the state of being opened at any time, the air pressure of the American nozzle S can also be adjusted and released, as described in the following paragraph.

Please refer to FIG. 2 and FIG. 5 together. FIG. 5 is a cross-sectional view of the pressure relief mechanism of a preferred embodiment of the present invention. The connector 4 of the present embodiment further includes a pressure relief mechanism 44 for discharging the gas in the air passage 43. Further, the pressure relief mechanism 44 of the present embodiment includes a button 441, a cap 442, a spring 443 and an O-ring 444, and the connecting seat 4 is provided with a consistent through hole 45, which is connected to the gas. The track 43 constitutes a communication. In addition, the cap 442 is disposed at one end of the through hole 45, and the button 441 is disposed at the other end of the through hole 45 and partially protrudes from the through hole 45, and the spring 443 is located between the cap 442 and the button 441, The ring 444 is sleeved on the button 441 and located between the button 441 and the inner wall of the through hole 45.

Accordingly, when the button 441 is pressed, a gap is formed between the button 441 and the inner wall of the through hole 45, and the gas in the air passage 43 is dissipated from the gap, so that the pressure can be released. More specifically, when the American joint end 21 of the two-way joint 2 is connected to the American air nozzle S, since the American valve Sv has been opened by the inner top member 213, it is continuously opened, and when the button 441 is pressed The gas in the American nozzle S will flow out through the gap formed between the button 441 and the inner wall of the through hole 45, so that the American nozzle S can be released.

On the other hand, the pressure relief mechanism 44 of the present invention can prevent the valve core of the French air nozzle P when connected to the French air nozzle P, except that it can be depressurized when connected to the American air nozzle S. ) Vc is loose. For further explanation, please refer to FIG. 4A together, the valve core Vc of some French air nozzles P is fixed by screw rotation, and the air pressure in the air nozzle is not removed, because the internal pressure of the air nozzle is high. State, and the seal (ie, O-ring) 24 will be pressed and tightly connected to the nozzle spool Vc. Therefore, if the joint is to be disengaged from the nozzle and the rotary sleeve 3 or the two-way joint 2 is rotated, there may be a gas. The nozzle spool Vc is rotated together to cause the nozzle spool Vc to be released. However, if the button 441 is pressed at this time, the pressure in the air nozzle (air pipe, air pump) can be removed, and the sealing member 24 is not pressed by the high air pressure. When the rotating sleeve 3 or the two-way joint 2 is rotated, the valve is rotated. The core Vc does not rotate with it, so that the nozzle core Vc can be prevented from coming loose.
