A dental handpiece switching connector comprises a connector body, a liquid delivery control valve, and a gas discharge control valve. The liquid delivery control valve is arranged in a liquid control valve vessel of the connector body. The gas discharge control valve is arranged in a gas control valve vessel of the connector body. By means of rotating the liquid delivery control valve, different liquids can be switched and supplied for the dental handpiece. By means of rotating the gas discharge control valve, the flow direction of a compressed gas can be controlled. Accordingly, the dentist can directly control the use of the liquid and the compressed gas without using an additional foot pedal for controlling.一種牙醫手機切換連接器,主要包括一連接器本體、一輸液控制閥及一出氣控制閥,該輸液控制閥係設於連接器本體之液體控制閥槽內,而該出氣控制閥則係設於連接器本體之氣體控制閥槽內,利用透過旋轉輸液控制閥,可切換供應牙醫手機不同液體使用,而透過旋轉出氣控制閥則可控制壓縮空氣之流向,使牙醫師可直接控制液體及壓縮氣體之使用,無需增加一個腳踏板做為控制使用。1‧‧‧連接器本體11‧‧‧輸液管12‧‧‧輸氣管13‧‧‧液體控制閥槽14‧‧‧氣體控制閥槽2‧‧‧輸液控制閥21‧‧‧輸液通道221‧‧‧單螺牙222‧‧‧單螺紋3‧‧‧出氣控制閥31‧‧‧出氣通道321‧‧‧單螺牙322‧‧‧單螺紋
