    • 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。

    • The power tool has a power transmitting mechanism. When a tool bit is not pressed against a workpiece, the power transmitting mechanism is held in a power transmission interrupted state, and when the tool bit is pressed against the workpiece, the power transmitting mechanism is held in a power transmission state in which the tool bit moves together with the driven-side member in an axial direction of the tool bit so that the driving-side member receives the torque from the driven-side member and the tool bit is driven. Tapered portions are provided between the driving-side member and the driven-side member and inclined with respect to the axial direction of the tool bit. When the driven-side member moves in the axial direction of the tool bit, frictional force is caused on the tapered portions and the torque of the driving-side member is transmitted to the driven-side member by the frictional force.
    • 电动工具具有动力传递机构。 当工具头没有被压在工件上时,动力传递机构保持在动力传递中断状态,并且当工具头被压靠在工件上时,动力传递机构保持在动力传递状态,其中工具 与从动侧构件一起沿着工具头的轴向移动,使得驱动侧构件从被驱动侧构件接受扭矩并且驱动工具头。 锥形部分设置在驱动侧构件和从动侧构件之间,并且相对于工具头的轴向倾斜。 当从动侧构件沿工具头的轴向移动时,在锥形部分上产生摩擦力,并且驱动侧构件的扭矩通过摩擦力传递到从动侧构件。

    • It is an object of the invention to provide an effective technique for preventing loss of a screw fastening depth regulating member removed from a machine body in a screw fastening machine. A representative screw fastening machine includes a machine body, a motor, an input shaft, an output shaft, a first clutch element, a second clutch element, a biasing member for first and second clutch elements, a screw fastening depth regulating member. The machine body has a holding part formed in an area other than the tip end region of the machine body to removably hold the screw fastening depth regulating member. The holding part is provided such that the screw fastening depth regulating member can be attached to and removed from the holding part by utilizing elastic deformation of the holding part.
    • 本发明的目的是提供一种有效的技术,用于防止在螺钉紧固机中从机体上移除的螺钉紧固深度调节件的损失。 代表性的螺丝紧固机包括机体,马达,输入轴,输出轴,第一离合器元件,第二离合器元件,用于第一和第二离合器元件的偏压元件,螺钉紧固深度调节元件。 机体具有形成在机体的顶端区域以外的区域中的保持部,以可拆卸地保持螺钉紧固深度调节构件。 保持部被设置成使得螺钉紧固深度调节构件可以通过利用保持部的弹性变形而附接到保持部分并从其移除。
