摘要： A power tool is provided which includes a motor assembly having a rotatable motor shaft mechanism, and a motor control coupled to the motor assembly and operable between a normal off condition de-energizing the motor and an on condition energizing the motor. The tool includes a rotatable tool shaft mechanism, and a clutch shiftable between a normal disengaged condition decoupling the motor shaft mechanism from the tool shaft mechanism and an engaged condition coupling the motor shaft mechanism to the tool shaft mechanism. A trigger member is engageable with both the motor control and the clutch and is moveable between a first position, wherein the motor control is in its off condition and the clutch is in its disengaged condition, and a second position holding the motor control in its on condition and the clutch in its engaged condition for driving the tool shaft mechanism. The trigger member is designed to prevent premature energization of the motor assembly.

摘要： A reversible ratcheting electric power tool has a reversible DC electric motor having an output coupled to drive a drive shaft through a reversible ratchet assembly. The tool housing has a reversing mechanism which includes a manually operable reversing cap rotatable about the axis of the drive shaft for controlling the ratcheting direction of the ratchet assembly, the cap having a pair of projections which respectively engage the actuator buttons of two direction control microswitches coupled through an on-off switch to a battery. When the ratchet assembly is in a neutral or non-ratcheting condition, both microswitches are in a normal deactuated condition connecting both of the motor terminals to the battery negative terminal. When the selector cap shifts the ratchet assembly to a forward ratcheting condition, one microswitch is actuated to connect one of the motor terminals to the battery positive terminal, and when the selector is moved to a reverse ratcheting direction, it actuates the other microswitch to connect the other motor terminal to the battery positive terminal.
摘要翻译：可逆棘轮电动工具具有可逆直流电动机，其具有联接以通过可逆棘轮组件驱动驱动轴的输出。工具壳体具有反转机构，其包括可围绕驱动轴的轴线旋转的可手动操作的反转盖，用于控制棘轮组件的棘轮方向，所述盖具有分别接合两个方向控制微动开关的致动器按钮的一对突起通过开关到电池耦合。当棘轮组件处于中性或非棘轮状态时，两个微动开关都处于将电动机端子连接到电池负极端子的正常停用状态。当选择器盖将棘轮组件移动到向前棘轮状态时，一个微动开关被致动以将电动机端子中的一个连接到电池正极端子上，并且当选择器移动到反向棘轮方向时，其致动另一个微动开关以连接另一个电机端子到电池正极端子。

摘要： A battery-powered driver tool has a tool housing with a socket-type coupler which receives a plug-type coupler of a battery pack in any of four different rotational orientations. Four keys on the battery pack are received in four keyways on the tool housing for non-rotatable engagement, the parts being retained by a split snap ring on the battery pack which cams past four cam shoulders on the tool housing, so that the parts automatically snap-engage and disengage in response to a simple push-pull motion. The battery pack includes a plurality of battery cells connected in series between positive and negative terminals which are designed to respectively engage positive and negative terminals on the tool housing in any of the four rotational orientations of the battery pack. The battery pack has a flat base surface, the parts being designed so that the tool/battery pack combination can be stood on the base surface in one rotational orientation of the battery pack.
