    • A medical or dental handpiece has a grip 3. The grip 3 includes first to third rotation shafts 101, 201, and 301. The first and second shafts are connected through a first gear mechanism 1000 and the second and third shafts are connected through a second gear mechanism 2000 so that a rotation is transmitted from the first shaft through the first gear mechanism to the second shaft and then from the second shaft through the second gear mechanism to the third shaft. The first or second gear mechanism has an internal gear secured on shaft and an external gear secured on the other shaft, the internal and the external gears being engaged with each other. The external gear is substantially enclosed within a cylindrical plane 1001, 2001 extending along a peripheral edge of the internal gear.

    • A connecting means for an illuminant handpiece being characterized in that the connecting device is adapted such that at least one of the electrical connections of the electric power receiving terminals of the illumination lamp and the electric power supply terminals is performed by fitting at a position close to the axis of the grip section almost symmetrically about the axis, and the other electrical connection is performed by fitting almost symmetrically about the axis or by abutting coaxially about the axis so as to permit a mutual rotation of the terminals. With this structure, the diameter of the connection area can be made small and the grip section can have an easy-to-hold size. In addition, the distance to the irradiation section can be reduced and efficient irradiation with less optical loss is obtained. Moreover, the space or lamp replacement can be reduced.
    • 一种用于发光手持件的连接装置,其特征在于,所述连接装置适于使得所述照明灯的电力接收端子和所述电源端子的至少一个电连接通过装配在靠近 把手部分的轴线基本上围绕轴线对称,而另一个电气连接是通过围绕轴线近似对称地配合或通过围绕轴线同轴地相配合来实现的,以允许端子相互旋转。 通过这种结构,可以使连接区域的直径变小,并且把持部分可以具有易于保持的尺寸。 此外,可以减少到照射部分的距离,并且获得具有较少光损耗的有效照射。 此外,可以减少空间或灯更换。
