Abstract

一种电动工具，包括：马达(1)；输出轴(2)，与工作头(21)配接；运动转换机构，连接所述马达和输出轴，能够将马达的旋转运动转换为轴向冲击传输给工作头；控制开关(30)，用于断开或接通电源和马达之间的电性连接；控制组件(50)，包括控制器(51)和电子开关(52)，电子开关位于马达和控制器之间，控制器控制电子开关的通断来对反映马达工作状态的特征变量进行间歇控制，使得所述电动工具的工作头间歇冲击，间歇冲击是与反复进行控制开关的开启与关闭操作时的效果相同，控制马达的电力供给实现间歇变化。该电动工具的工作头间歇地冲击，从而有效地减小了电动工具对瓷砖面的有害损失，避免在钻孔过程中，持续的作用力作用在瓷砖上，导致瓷砖破裂的情况。还涉及该电动工具的控制装置。
