摘要： A drill 30 for driving a bit 44 into a workpiece 50 includes an assembled anvil 58 and spindle 38, which are mounted for rotation together and for axial movement together within a drill housing 32. A planet carrier 56 is driven by a motor 52 and, in turn rotatingly drives the anvil 58 and the spindle 38. A chuck 42 is attached to a forward end of the spindle 58 for rotation and axial movement therewith. A plurality of rollers 162 are mounted in nests 182 of a roller cage 176, are maintained in parallel with an axis of the drill 30, and the anvil 58. The rollers 162, which are included in an automatic spindle lock 33, can be wedged between a fixed surface 74 of the drill housing 32 and a movable surface 102 of the anvil for automatically locking the spindle 38 with the housing. Following withdrawal of the bit 44 from the workpiece 50, an automatic brake 35 provides facility for braking the spindle 38. When the planet carrier 56 ceases to be driven, the anvil 58 and the spindle 38 are in a coasting mode relative to the slowing speed of the planet carrier 56. An automatic drag system 37 provides a drag between the coasting anvil 58 and the planet carrier 56 to bring the coasting speed of the anvil generally in line with the slowing speed of the planet carrier.

摘要： A tool bit such as a screw driving bit for use with a rotary power tool is conventiently stored in a cavity in the rotary power tool housing when not in use in a power tool chuck. The tool bit is retained in the recess by frictional engagement with a retainer spring. A push-button protruding from the rotary tool housing communicates with the bit holding cavity and retainer spring in a manner such that, upon depression of the push-button, the retainer spring is moved out of frictional engagement with the bit to enable its release from the storage cavity.
摘要翻译：当不用于电动工具卡盘时，诸如用于旋转动力工具的螺丝驱动钻头的工具钻头被有效地存储在旋转动力工具壳体中的空腔中。工具头通过与保持弹簧的摩擦接合而保持在凹部中。从旋转工具壳体突出的按钮与钻头保持腔和保持器弹簧连通，使得当按压按钮时，保持器弹簧移动离开与钻头的摩擦接合，以使其能够从储存腔。

摘要： A depth-adjusting system for a power tool includes a housing nose portion on which is snapped a two-piece, molded plastic depth-adjusting subassembly. Each member of the subassembly engages a respective area of the nose portion. An adjustment member is rotatably connected to the nose portion, but is releasably restrained from axial movement upon engagement with a split-ring detent on the nose portion. A locator member is threadably connected inside the adjustment member, but is restained from rotating through the interaction of integral keys formed on its interior cylindrical surface with mating longitudinal keyways formed on the nose portion. Thus when the operator rotates the adjustment member, the locator member is forced to move axially forwardly or rearwardly, depending upon the direction of rotation of the adjustment member. Another feature of this system is the use of protuberances integrally formed in the rear axial end of the locator member to inhibit lock-up between the locator member and the adjustment member after the locator member has been drawn inwardly to its rearmost position.
摘要翻译：用于电动工具的深度调节系统包括壳体鼻部，其上卡住了两件式的模制塑料深度调节子组件。子组件的每个构件接合鼻部的相应区域。调节构件可旋转地连接到鼻部，但是当与鼻部上的开口棘爪卡合时可释放地限制其轴向运动。定位器构件螺纹连接在调节构件内部，但是通过形成在其内部圆柱形表面上的整体键与形成在鼻部上的配合纵向键槽的相互作用而旋转。因此，当操作者旋转调节构件时，取决于调节构件的旋转方向，定位构件被迫轴向向前或向后移动。该系统的另一个特征是使用定位器构件的后轴向端部整体形成的突起，以在定位构件被向内拉到其最后位置之后阻止定位构件与调节构件之间的锁定。
