    • A power tool that includes a pipe holder, a knife pivotally coupled to the pipe holder, and a drive mechanism coupled to at least one of the pipe holder and the knife. The power tool also includes a motor coupled to a drive mechanism, and a removable and rechargeable battery pack coupled to the motor to selectively provide power signals to the motor. The power tool also includes a controller configured to monitor a plurality of conditions of the power tool, such as battery pack voltage, battery pack temperature, operational current, and the like. The controller is also configured to detect one or more events related to the plurality of conditions of the power tool. For example, the controller is configured to monitor the operational current of the power tool. If the operational current of the power tool exceeds a first threshold value, a power signal duty cycle is reduced from a first duty cycle value to a second duty cycle value to limit the amount of torque the power tool is able to generate.
    • 一种电动工具,其包括管支架,可枢转地联接到管保持器的刀和联接到管支架和刀的至少一个的驱动机构。 电动工具还包括耦合到驱动机构的电动机,以及耦合到电动机的可移除和可充电电池组,以选择性地向电动机提供电力信号。 电动工具还包括被配置为监视电动工具的多个状态的控制器,例如电池组电压,电池组件温度,工作电流等。 控制器还被配置为检测与电动工具的多个条件相关的一个或多个事件。 例如,控制器被配置为监视电动工具的工作电流。 如果电动工具的工作电流超过第一阈值,则功率信号占空比从第一占空比值减小到第二占空比值,以限制电动工具能产生的转矩量。

    • An arbor assembly for connecting a cutting tool to a power tool includes a shaft defining a longitudinal axis and having an end portion configured to couple to the cutting tool, and a plate surrounding a portion of the shaft adjacent to the end portion. The plate has a first surface configured to engage the cutting tool when the cutting tool is coupled to the shaft and a second surface substantially opposite the first surface. The plate is movable along the longitudinal axis relative to the shaft. The arbor assembly also includes a wedge member positioned adjacent to the second surface of the plate and defining an opening to receive a portion of the shaft. The wedge member is movable relative to the plate from a first position, in which the plate is inhibited from moving along the longitudinal axis away from the end portion, to a second position, in which the plate is movable along the longitudinal axis away from the end portion.

    • A hole saw that includes a saw body including a circular cutting edge having a cutting edge diameter, and the saw body is coupled to a guide member for rotation with the guide member. A pilot is coupled to the guide member for movement relative to the guide member and the saw body, and the pilot includes an outer guide surface having a diameter that increases in a direction from a second end portion of the guide member toward a first end portion of the guide member. The pilot is coupled to the guide member such that at least a portion of the outer guide surface extends past the circular cutting edge of the saw body in a direction from the first end portion of the guide member toward the second end portion of the guide member.
    • 一种孔锯,其包括具有切削刃直径的圆形切削刃的锯体,并且所述锯体与所述引导构件联接,以与所述引导构件一起旋转。 引导件联接到引导构件以相对于引导构件和锯体移动,并且引导件包括外引导表面,外引导表面的直径在从引导构件的第二端部朝向第一端部的方向上增大 的引导成员。 引导件联接到引导构件,使得外引导表面的至少一部分沿着从引导构件的第一端部朝向引导构件的第二端部的方向延伸超过锯体的圆形切割边缘 。

    • A hand saw that includes a saw blade and a handle assembly having a clamp member movable between a clamped position and a released position. In the clamped position the clamp member exerts a clamping force on a top edge of the saw blade within a slot of the handle assembly to couple the saw blade to the handle assembly and to retain a tang of the saw blade within the slot. In the released position the tang is removable from the slot. A first interior wall and a second interior wall of the handle assembly that define the slot are flat such that the tang of the saw blade can be removed from the slot without moving the saw blade in a direction normal to a longitudinal axis of the saw blade when the clamp member is in the released position.
    • 一种手锯,其包括锯片和具有可在夹紧位置和释放位置之间移动的夹紧构件的手柄组件。 在夹紧位置,夹紧构件在手柄组件的狭槽内在锯片的顶部边缘上施加夹紧力,以将锯片联接到手柄组件并且将锯片的柄脚保持在狭槽内。 在释放位置,脚可从插槽中移除。 限定狭槽的手柄组件的第一内壁和第二内壁是平坦的,使得锯片的柄脚可以从狭槽移除,而不会沿着垂直于锯片的纵向轴线的方向移动锯片 当夹紧构件处于释放位置时。
