摘要： A motion conversion assembly is provided, wich is adapted to be attached to a power drill for converting rotational motion of the drill to a reciprocating motion to operate as a reciprocating saw. The motion conversion assembly is mounted in a housing, and employs an offset-angled spindle on a rotatable drive shaft which is coupled to an intermediate shaft sub-assembly in the housing, which cooperated whith the offset-angled apindle to produce a reciprocating motion in the intermediate shaft subassembly as the rotatable drive shaft is rotated.
摘要翻译：提供了一种运动转换组件，其适于附接到电钻上，用于将钻头的旋转运动转换成往复运动，以作为往复锯操作。运动转换组件安装在壳体中，并且在可旋转的驱动轴上采用偏置角度的主轴，该主轴联接到壳体中的中间轴子组件，其与偏移角度的主轴协作以产生往复运动作为可旋转驱动轴的中间轴子组件旋转。

摘要： A drill sharpener is provided which has a point-splitting port which simplifies the procedure for producing a split point on a drill bit undergoing sharpening. The point-splitting port is positioned relative to a grinding wheel assembly such that, when the drill held by a chuck is advanced toward the grinding wheel, a flute of the drill at the drill tip is brought into contact with the grinding wheel. The port has alignment stops therein which mate with flats provided on the barrel of the chuck to ensure proper alignment of the chuck and drill relative to the grinding wheel. The stops also limit the extent of inward travel of the chuck and drill to a predetermined distance. A debris or grit collection tube is also provided to be inserted into an unused port of the drill sharpener, to contain and confine any debris or grit attempting to exit the sharpener through the unused port.
摘要翻译：提供了一种具有分切口的钻削刀，其简化了在经历磨削的钻头上产生分裂点的过程。分切口相对于砂轮组件定位，使得当由卡盘保持的钻头朝向研磨轮前进时，钻头的钻头的凹槽与砂轮接触。该端口在其中具有对准止动件，其与设置在卡盘的筒体上的平面配合，以确保卡盘和钻头相对于砂轮的适当对准。止动件还限制卡盘和钻头向内行进到预定距离的程度。还提供碎屑或砂粒收集管以插入钻削刀的未使用的端口中，以容纳和限制试图通过未使用的端口离开磨刀机的任何碎屑或砂粒。
