    • A power tool includes a housing assembly, a motor, a pipe holder, and a knife pivotally coupled to the pipe holder at a pivot point for movement relative to the pipe holder. The knife is operable to pivot through an angle toward the pipe holder during a cutting motion and is operable to pivot through the angle away from the pipe holder during a return motion. The power tool also includes a drive mechanism having a first gear coupled to the motor and a second gear coupled to the knife. The power tool further includes a release mechanism coupled to the drive mechanism. The release mechanism is operable to selectively disconnect the second gear from the knife so that movement of the motor is not transmitted to the knife and the knife is movable through the angle away from the pipe holder.
    • 电动工具包括壳体组件,电动机,管道保持器和在相对于管道保持器运动的枢轴点处可枢转地联接到管道保持器的刀。 刀可操作以在切割运动期间朝向管支架枢转一定角度,并且可操作以在返回运动期间枢转穿过管夹。 动力工具还包括具有联接到马达的第一齿轮和联接到刀的第二齿轮的驱动机构。 动力工具还包括联接到驱动机构的释放机构。 释放机构可操作以选择性地将第二齿轮与刀具断开,使得马达的运动不传递到刀具,并且刀可以移动穿过远离管座的角度。
