由以上說明可知，本新型除了結構創新之外，由於該氣嘴連接單元5可轉動的安裝在該基座4的該組裝通道43內，且該氣嘴連接單元5的該氣嘴安裝部53及該操控部54分別位於該組裝通道43相反側，同時該控氣件61的該壓控部612與該操控部54位於同側的元件配置關係，確實可以讓組卸該第一氣嘴3及該第二氣嘴3’的操作更為順手，同時提高充氣操作的方便性。且本新型該阻氣環62是藉由該固定環64固定的安裝在該氣嘴連接單元5的該銜接部55內，在操作過程中不會滑移切過任何孔洞的銳利面，前述結構可以降低該阻氣環62異常磨耗，以降低氣密不足的漏氣風險。As can be seen from the above description, in addition to the structural innovation, the air nozzle connecting unit 5 is rotatably mounted in the assembly passage 43 of the base 4, and the nozzle mounting portion 53 of the air nozzle connecting unit 5 is provided. And the control portion 54 is located on the opposite side of the assembly channel 43, and the voltage control portion 612 of the air control member 61 and the control portion 54 are disposed on the same side of the component arrangement relationship, and the first nozzle 3 can be unloaded. And the operation of the second air nozzle 3' is more convenient, and the convenience of the inflation operation is improved. The gas block 62 of the present invention is fixed in the connecting portion 55 of the nozzle connecting unit 5 by the fixing ring 64, and does not slip through the sharp surface of any hole during the operation. The foregoing structure The abnormal wear of the gas barrier ring 62 can be reduced to reduce the risk of air leakage with insufficient airtightness.
惟以上所述者，僅為本新型的實施例而已，當不能以此限定本新型實施的範圍，凡是依本新型申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本新型專利涵蓋的範圍內。However, the above is only the embodiment of the present invention.
