    • A pipe cutter for cutting a pipe includes a cutting head assembly having a first carriage and a second carriage spaced apart to define a cutting area. The first carriage supports a cutting mechanism, and the second carriage is configured to support a pipe within the cutting area. The carriages have a locked state and an unlocked state such that when the carriages are in the unlocked state, the carriages are movable relative to each other and biased into the cutting area. The pipe cutter also includes a drive assembly configured to rotate the cutting head assembly and a locking mechanism configured for changing the carriages from the unlocked state to the locked state and for holding the carriages in the locked state. The locking mechanism includes an actuation member rotatably coupled to the first carriage.
    • 用于切割管道的管道切割器包括具有第一托架和间隔开以限定切割区域的第二托架的切割头组件。 第一托架支撑切割机构,第二托架构造成在切割区域内支撑管道。 托架具有锁定状态和解锁状态,使得当托架处于解锁状态时,托架可相对于彼此移动并且被偏压到切割区域中。 管道切割器还包括构造成旋转切割头组件的驱动组件和被构造用于将滑架从解锁状态改变到锁定状态并用于将滑架保持在锁定状态的锁定机构。 锁定机构包括可旋转地联接到第一托架的致动构件。

    • A power tool, such as a pipe cutter, includes a rotatable cutting head assembly, an electric motor connectable to a rechargeable battery, and a controller. The controller is configured to monitor the state of charge on the battery, compare the state of charge to one or more thresholds, and prevent or limit operation of the power tool when the state of charge is less than or equal to one or more of the thresholds. In some embodiments, the threshold includes the state of charge required to cut a pipe, the state of charge required to return the cutting head assembly to a home position, and a state of charge indicative of an overdischarged condition of the battery. In some embodiments, the controller is configured to detect when the pipe cutter has completed cutting the pipe and returns the cutting head assembly to the home position.
    • 诸如管道切割器的电动工具包括可旋转切割头组件,可连接到可再充电电池的电动马达和控制器。 控制器被配置为监视电池的充电状态,将充电状态与一个或多个阈值进行比较,并且当充电状态小于或等于一个或多个时,防止或限制电动工具的操作 阈值。 在一些实施例中,阈值包括切割管道所需的电荷状态,将切割头组件返回到原始位置所需的电荷状态以及指示电池的过度放电状态的充电状态。 在一些实施例中,控制器被配置为检测管切割器何时完成切割管并将切割头组件返回到原始位置。

    • A hand saw that includes a frame, a lever, and a rod movable in a first direction to increase a distance between a first blade support and a second blade support and the rod is movable in a second direction to decrease the distance between the first blade support and the second blade support. The rod is coupled to the lever and the frame such that the rod is movable in the first direction and with the lever when the lever moves from a release position toward a tension position in order to tension the blade. The rod is coupled to the lever and the frame such that the rod is movable with respect to the frame in the first direction and the second direction and movable in the first direction and the second direction independent of the lever when the lever is in the release position.
