摘要： A power tool includes a body housing a motor with a first output shaft and an attachment for engagement with the output shaft. The attachment includes an output shaft which transmits rotational motion derived from the rotational motion of the motor and further includes a gear mechanism enabling a gear change in rotational speed between its input and output. A combination of the body and the attachment thereby provides a plurality of serially-coupled gear mechanisms.
摘要翻译：一种动力工具包括一个主体，其容纳具有第一输出轴的马达和用于与输出轴接合的附件。附件包括输出轴，该输出轴传递从马达的旋转运动导出的旋转运动，并且还包括能够在其输入和输出之间进行齿轮转速的齿轮机构。主体和附件的组合由此提供多个串联耦合的齿轮机构。

摘要： A first component part (42) for a power tool has a mounting spigot (90) with a channel (239) therein and a second component part (10) of the power tool has a spigot receiving portion (54) with a rib (101) co-operable with the channel. The first component part includes a cylindrical projection with a chamfered edge (250) and the second component part includes a detent. In a first step in coupling the components parts, the channel in the mounting spigot is aligned with the co-operable rib on the spigot receiving portion. Subsequent steps include engaging the further rib of the spigot receiving portion with a channel on a side wall and finally, urging the chamfered edge past the detent.
摘要翻译：用于动力工具的第一部件（42）具有安装插口（90），其中具有通道（239），并且电动工具的第二部件（10）具有带肋（101）的插口接收部分（54））与频道合作。第一部件包括具有倒角边缘（250）的圆柱形突出部，并且第二部件包括棘爪。在联接部件的第一步骤中，安装插口中的通道与插口接收部分上的可协作肋对准。随后的步骤包括将插口接收部分的另外的肋部与侧壁上的通道接合，并且最终将倒角的边缘推动通过制动器。

摘要： An interlock mechanism for a power tool is provided to releasably couple first and second portions of the power tool. The mechanism includes a spring normally biased into a closed position and an actuator enabling the spring to be moved to an open position. The actuator has a spring-engaging surface formed from several individual surfaces which are non coplanar.

摘要： A power tool includes a leveling device which includes a rotatable member which seeks an equilibrium position which corresponds to a level position. A rotating device includes a member which enables passage of a beam. An electrical circuit which includes an emitting device, a receiving device and an indicating device is electrically coupled such that upon activation, the emitting device emits a beam which passes through the beam passing member. The beam is received by the receiving device which, in turn, activates the indicator device. The indicator is generally a light emitting device which has a varying brightness so that the user may view the indicator from all sides of the power tool.

摘要： A coupling mechanism for a power tool is provided on one portion of the tool and comprises a generally cylindrical projection with a side wall having a radial recess extending part-circumferentially along the side wall. A further projection is formed on the side wall which extends in both directions parallel to the axis of the cylindrical projection and in a direction radially outward from the side wall as well.
