Please refer to FIG. 3 , which is a schematic diagram of the multi-purpose air nozzle structure provided by the present invention when a French air nozzle A is attached. Since the French air nozzle A has a small outer diameter and a long length, the French air nozzle A can reach the The receiving port passes through the receiving hole 251 and penetrates into the pressing space 216 to connect with the mouthpiece 24 . At this time, according to the length of the French valve A in the pressing space 216 , the mouthpiece 24 is displaced. At the opposite position in the pressing space 216, and at the same time, the spring 23 disposed in the pressing portion 211 continues to give the mouthpiece 24 the thrust, so that the mouthpiece 24 can be tightly connected to the French valve A Press the butt without creating a gap. When the pull rod 42 is rotated so that the cam pull rod 40 exhibits the pressing state, the pressing section 221 penetrates into the pressing hole 214 and protrudes from the pressing space 216 , and at this time the pressing section 221 can abut against the mouthpiece 243 to prevent the mouthpiece 24 from moving in the pressing space 216, preferably the pressing section 221 can abut against the mouthpiece 243 and the outer wall of the French valve A at the same time, so that the mouthpiece The joint between 24 and the French valve A can be more tight. When the airflow enters the receiving space 11 through the inflation port 121 , the airflow further enters the pressing space 216 through the airflow hole 215 on the pressing member 21 , and at this time, the airflow can pass through the spring The air passage 241 at the end opens and the air passage 244 enters the mouthpiece 24 and inflates toward the French air nozzle A.

Please refer to FIG. 4 , which is a schematic diagram of the multi-purpose air nozzle structure provided by the present invention when an American-style air nozzle B is connected. Since the American-style air nozzle B has a larger outer diameter, when the American-style air nozzle B goes deep into the socket, The end of the American valve B is blocked by the small diameter part and can only be accommodated in the large diameter part. At this time, the nozzle piece 24 is pressed by the thrust of the spring 23 so that the nozzle piece 24 passes through the small diameter part Butt against the American valve B. When the pulling rod 42 is rotated so that the cam pulling rod 40 exhibits the pressing state, the pressing section 221 penetrates into the pressing hole 214 and protrudes from the pressing space 216 against the mouthpiece 24 in the direction of the pressing end 112 . The outer wall can prevent the mouthpiece 24 from moving in the pressing space 216 . When the airflow enters the receiving space 11 through the inflation port 121 , the airflow further communicates directly with the airflow channel 244 through the airflow perforation 215 and enters the mouthpiece 24 to inflate toward the American air nozzle B.

Through the extrusion of the spring 23, the multi-purpose air nozzle structure provided by the present invention enables the nozzle piece 24 to conform to the different lengths of the air nozzles in a deep and close corresponding engagement; the push of the cam lever 40 makes the pressing piece 22 It can protrude from the pressing space 216 against the outer wall of the mouthpiece 243 to prevent the mouthpiece 24 from being easily displaced by the pressing space 216 , and can also prevent the connection between the mouthpiece 24 and the air nozzle from being dislocated, ensuring the Multi-use pump structure effect and quality.
