    • An impact power tool includes an impact mechanism for applying a striking impact to an output shaft by using an output power of a motor. A strike detection unit detects the striking impact applied by the impact mechanism to obtain a striking timing and a striking speed detection unit calculates a striking speed from the striking timing obtained by the strike detection unit and a rotation angle of the motor obtained by a rotation angle detection unit. A control unit counts the number of striking impact detected by the strike detection unit and stops the motor if the number of striking impact reaches a predetermined strike number. The control unit is designed to correct the predetermined strike number when the striking speed obtained in the striking speed detection unit is equal to or lower than a specified striking speed.
    • 冲击动力工具包括用于通过使用马达的输出功率对输出轴施加撞击冲击的冲击机构。 击打检测单元检测冲击机构施加的冲击冲击以获得打击定时,并且击打速度检测单元根据由击打检测单元获得的打击定时和通过旋转角得到的马达的旋转角度来计算打击速度 检测单元 控制单元计数由罢工检测单元检测到的冲击冲击次数,并且如果撞击次数达到预定罢工次数,则停止马达。 控制单元被设计成当在打击速度检测单元中获得的打击速度等于或低于指定的打击速度时,校正预定的打击次数。
