    • An adapter coupling device includes an adapter having a polygonal recess for receiving a bit therein and a radial hole is defined in an outer periphery of the adapter so as to receive a bead therein. A spring and a positioning block are received in the adapter and the positioning block includes stepped receiving space and an outer surface. An outer sleeve is mounted to the adapter and a spring is located therebetween. The outer sleeve has a annular groove and an inclined inner surface defined in the inner periphery thereof, wherein the inclined inner surface has a maximum inclination of 30 degrees relative to an axis of the outer sleeve. The bit can be inserted into the polygonal recess of the adapter by one hand without pushing the outer sleeve upward. The inclined inner surface of the outer sleeve pushes the bead to position the bit.
    • 适配器联接装置包括具有用于在其中容纳钻头的多边形凹槽的适配器,并且径向孔限定在适配器的外周中,以便在其中容纳珠子。 弹簧和定位块被容纳在适配器中,并且定位块包括阶梯式接收空间和外表面。 外套筒安装在适配器上,弹簧位于其间。 外套筒具有环形槽和限定在其内周中的倾斜内表面,其中倾斜内表面相对于外套筒的轴线具有30度的最大倾角。 钻头可以用一只手插入适配器的多边形凹槽中,而不向上推动外套筒。 外套筒的倾斜内表面推动胎圈来定位刀头。

    • A bit holder assembly includes a socket with a sleeve movably mounted thereto and two springs are located between the socket and the sleeve. The two springs have two respective end sections which are engaged with two inclined slots defined in the wall of the socket. The two end sections protrude into ⅕ of the inner diameter of the socket. An inner spring is located in the socket. The axial height of the first slot is larger than or equal to the axial height of the notches of the bit, and the axial height of the second slot is larger than or equal to an axial height of the annular groove of the bit. An angle between the axis of the socket and the first and second slots is smaller than 60 degrees.
    • 位保持器组件包括具有可移动地安装到其上的套筒的插座,并且位于插座和套筒之间的两个弹簧。 两个弹簧具有两个相应的端部部分,其与限定在插座的壁中的两个倾斜槽接合。 两个端部突出到插座内径的。内。 内部弹簧位于插座中。 第一槽的轴向高度大于或等于钻头槽口的轴向高度,第二槽的轴向高度大于或等于钻头的环形槽的轴向高度。 插座的轴线与第一和第二槽之间的角度小于60度。
