A kind of dental handpiece integrated test machine, for testing high, low speed dental handpiece. The dental handpiece is made of with integrated test machine a box-structure, and structure has electric notor manipulation unit, one or six hole modular connection units, an electronic display unit, flow test units composition. The electric notor manipulates unit and is made of an electric notor socket, electric notor speed regulation button, electric motor drive switch, the positive and negative turn-button of an electric notor, an electric notor illumination button, electric notor manipulation unit can link with dental electric motor, make to drive electric motor rotation, link it with low speed mobile phone by the electric motor driven, and then drives the rotation of low speed mobile phone. The six holes modular connection unit is made of one or six hole modular connection sockets, one or six hole modular connections switching switch, a high speed handpiece driving switch, a high speed handpiece illumination button, six hole modular connection units can link with dental air motor, make to drive the rotation of low speed mobile phone； Can with tie in succession fastly, make drive high speed handpiece rotation, or be directly connected to high speed handpiece make driving rotate. The electronic display unit is made of an inductor, a voltage display table, one ampere of display table, a revolving speed display table, can sense high speed handpiece and low speed mobile phone in rotation, voltage and current and revolving speed when rotating detection. The flow test units by a water supply test flowmeter, a water supply test air gauge, one supply water test switch, one for mist test flowmeter, one for mist test air gauge, one for mist test switch, one gas supply test flowmeter, one gas supply test air gauge, one gas supply test with switch form, can be used to detect the water supply of high speed handpiece or low speed mobile phone, for mist, for airway dysfunction.
