    • A power tool that includes a driving motor and a power transmitting mechanism. The power transmitting mechanism includes a first clutch cam part, a second clutch cam part, clutch teeth, a clutch detecting mechanism and a controller that can control the driving motor in a first control mode in which the driving motor is controlled to rotate at a first rotation speed until before the first and second clutch cam parts are engaged with each other at the clutch teeth and in a second control mode in which the driving motor is controlled to rotate at a second rotation speed higher than the first rotation speed after the first and second clutch cam parts are engaged with each other at the clutch teeth.
    • 一种电动工具,其包括驱动电动机和动力传递机构。 动力传递机构包括第一离合器凸轮部,第二离合器凸轮部,离合器齿,离合器检测机构和控制器,其能够以驱动电机被控制为以第一方式旋转的第一控制模式来控制驱动电动机 旋转速度直到第一离合器凸轮部分和第二离合器凸轮部分在离合器齿之间彼此接合,并且在第二控制模式中,其中驱动电机被控制为在第一和第二离合器凸轮部分的第一转动之后以比第一转速高的第二转速旋转, 第二离合器凸轮部分在离合器齿处彼此接合。
