摘要： A power tool, such as a hedgetrimmer, comprising a motor (5), typically electric, a blade set (2, 3) comprising at least one blade (2, 3) driven for reciprocating motion by the motor (5) and a drive train (6) connecting the motor (5) to the blade set (2, 3), the drive train (6) having a coupled state in which motion of the motor (5) is coupled to the blade set (2, 3) and an uncoupled state in which motion of the motor (5) is not coupled to the blade set (2, 3), the drive train (6) being capable of sudden transition from the uncoupled state to the coupled state so as to transfer angular momentum built up in the motor (5) or the drive train (6) to the blade set (2, 3). This allows for a hammer action to be provided to the blades, so that a strong impulse, larger than the force normally exerted by the blade set can be transmitted to the blade set for particularly stubborn obstacles. The drive train may comprise a centrifugal clutch (10), arranged to engage suddenly once the rotational speed of an output shaft (7) of the motor (5) increases above a first threshold and to disengage once the rotational speed of the output shaft (7) drops below a second threshold.
摘要翻译：一种电动工具，例如电动工具，其包括通常电动的电动机（5），包括用于由电动机（5）往复运动驱动的至少一个叶片（2,3）的叶片组（2,3）将马达（5）连接到叶片组（2,3）上的列车（6），具有马达（5）的运动联接到叶片组（2,3）的联接状态的传动系（6）以及电动机（5）的运动未联接到所述叶片组（2,3）的非耦合状态，所述传动系（6）能够从所述非耦合状态突然转变到所述耦合状态，以便传递角在马达（5）或传动系（6）中积聚到叶片组（2,3）的动量。这允许对叶片提供锤击动作，使得比通常由刀片组施加的力更大的强冲击可以被传递到用于特别顽固的障碍物的刀片组。传动系可以包括离心式离合器（10），其一旦马达（5）的输出轴（7）的旋转速度增加到高于第一阈值并且一旦输出轴的转速（ 7）下降到第二阈值以下。
