摘要： A power tool includes: a motor configured to be driven based on one of a plurality of drive modes; a mode section switch; a control portion. The control portion is configured to operate responsive to a first operation to assign one or more drive modes preselected from the plurality of drive modes to the mode selection switch. A second operation different from the first operation is capable of manipulating the mode selection switch to select one drive mode from the one or more preselected drive modes, the control portion being further configured to control the motor based on the one drive mode selected by the mode selection switch.

摘要： A power tool which has an anvil 20 that is rotated by a hammer 22 and is housed in a housing, and rotates an output shaft 18 is provided. The anvil 20 and the output shaft 18 are integrally formed into one unit, and a carrier 33 that is rotatable relative to the anvil 20 by a predetermined angle on the same axis is provided. On one portion of an outer circumferential surface of the anvil 20, a relief surface 20a is formed. Cut-out portions 33b are formed at positions opposed to each other of a carrier 33, and by allowing an engaging pin 37 to be interposed therein, a locking mechanism that limits the relative rotation between the anvil 20 and a lock ring 38 is prepared. When the tool main body is manually rotated while the hammer 22 is being stopped, the engaging pin 37 limits the relative rotation between the anvil 20 and the lock ring 38. The locked state between the anvil 20 and the lock ring 38 is released immediately when the rotation of the motor 4 is started.
摘要翻译：提供了一种电动工具，该电动工具具有通过锤子22旋转并被容纳在壳体中并且使输出轴18旋转的砧座20。砧座20和输出轴18一体地形成为一个单元，并且在相同的轴线上设置有能够相对于砧座20旋转规定角度的行星架33。在砧座20的外圆周表面的一部分上形成后刀面20a。切口部分33b形成在托架33的彼此相对的位置处，并且通过允许插入接合销37，准备了限制砧座20和锁定环38之间的相对旋转的锁定机构。当在锤子22停止时手动旋转工具主体时，接合销37限制砧座20和锁定环38之间的相对旋转。当砧座20和锁定环38之间的锁定状态被立即释放马达4的旋转开始。
