' 5 [Prior Art] Φ As in the case of Taiwan's new 135498 patent (US 5,960,815), please sign the first picture, which reveals a body (18) and two connections in a housing (1〇) content. The mouth (14) (15), the body (18) is provided with a branching valve chamber (21), and the content 1 is provided with a super-flow blocking member (32). The airflow generated by the inflating action causes the superfluid blocking member (32) to block the communicating air hole of the vacant nozzle, and achieves the function of automatically switching the selection nozzle. [Invention] The main purpose of the present invention is to provide another automatic switching. Select the inflator nozzle connector of the nozzle. In order to achieve the above object, a gas nozzle joint of an inflator having an automatic switching selection nozzle according to the present invention comprises: a casing having an intake passage; and a branching chamber disposed in the casing, The two inlet nozzles are connected to each other; the two nozzle assemblies are disposed in the casing, and each of the first-class passages communicates with the aforementioned divided chambers, and each of the communicating portions forms an air hole; and an automatic switching member is disposed in the middle. Toward the room, a swing arm is formed on each side of the pivot shaft, and the two swing arms can pivot up and down for the axis, and one of the two nozzle arms closes one of the corresponding two nozzle assemblies. 4 1284722 [Embodiment] An embodiment is described with reference to the following figures: As shown in the figure, the nozzle joint of the embodiment of the invention comprises: 5 - a casing (40) having an intake passage (41), In connection with the air flow path (not shown) of the inflator, in this embodiment, a plug connector (42) is provided at the outer end of the air inlet channel (41) for plugging a hose (not shown), and then a plug The cover (43) is screwed into the preset thread (44) of the housing, and this type can be used for an inflator with an inflation hose such as a floor pump. The shell can also be directly connected to the pump without the need to connect through a hose, such as a Hand Pump or a Mini pump. A branching chamber (46) is disposed in the casing (4〇) and communicates with the aforementioned intake passage (41). The two nozzle assemblies (50) (60) are disposed in the casing (4〇), and each of the first-class passages (52) (62) I5 communicates with the aforementioned dividing chamber (46), and each of the communicating portions forms an air hole ( 53) (63). A switching member (90) is pivotally disposed in the centering chamber (46), and a swing arm (91) (92) is formed on each side of the pivot shaft, and the second swing arm (91) (92) can be pivoted (93) Swing up and down for the axis, such as a see-up plate shape, and close one of the corresponding two nozzle assemblies (5〇) (6〇) with one of the two swing arms (91) (92). 2〇(53)(63). Used to close the flow channel (52) or the flow channel (62). The second swing arm (91) (92) of the switching member (90) of the present embodiment is not in the same plane, and has an 'angle between the two. As shown in the fourth figure, when the swing arm (92) is closed, the air hole is closed. (63), the other-swing arm (91) is upwards, and the other air hole (9) is opened (as shown in the sixth figure). 5 1284722 (Prestavalve) (shown as imaginary line 120 in the figure), the top abutting member (65) is pushed up to open the swing arm (92), so that the air hole (63) is open and the other swing arm (91) Move down and close the air hole (53), then pull the trigger (8〇) to deform the elastic sleeve (51) (61) and clamp the French valve with the elastic sleeve (61) (12〇) ). After the inflation is completed, simply pull back the trigger member (8〇) to abut the first end surface (82) with the housing (40), and then return the elastic sleeve (51) (61) to its original shape and put it back. Open the clamped valve. The invention replaces the ball structure of the previous case with a seesaw structure, and the structure is simple and the operation is reliable. 1284722 [Simple description of the drawing] The first figure is a schematic diagram of the structure of the conventional double nozzle joint. The second figure is a front view of an embodiment of the present invention. The third figure is a bottom view of an embodiment of the present invention. 5 The fourth figure is a cross-sectional view taken along the line A-A in the third figure. The fifth drawing is a cross-sectional view taken along line B-B in the second drawing. Figure 6 is a schematic view showing the state of use of the embodiment of the present invention. The seventh figure is a schematic diagram of another use state of the embodiment of the present invention.
