摘要： A hand-held power tool for pruning and cutting vegetation and a method for replacing blades thereof. The hand-held power tool has a main body and a work head detachably mounted on the main body. The main body has a housing, a motor placed in the housing, and a first gear transmissively connected with the motor. The work head has a blade assembly and a second gear. The second gear engages with the first gear and is provided with a eccentric member connected with the blade assembly. By arranging one portion of the transmission mechanism on the work head, especially the second gear used for providing the eccentrically rotary output on the work head, the transmission mechanism is directly connected with the blade assembly. When the work head needs to be mounted on the main body, it only needs the second gear to be placed on the mandrel arranged on the main body where it will engage with the first gear. This avoids the need to align and mate the eccentric member arranged on the second gear with the upper and lower blades one by one thereby providing an assembly process that is simple and time-saving while providing a connection that is reliable.
摘要翻译：一种用于修剪和切割植被的手持式电动工具及其更换叶片的方法。手持式电动工具具有可拆卸地安装在主体上的主体和工作头。主体具有壳体，放置在壳体中的电动机和与电动机透射连接的第一齿轮。工作头具有刀片组件和第二齿轮。第二齿轮与第一齿轮啮合并且设置有与叶片组件连接的偏心构件。通过将传动机构的一部分布置在工作头上，特别是用于在工作头上提供偏心旋转输出的第二齿轮，传动机构直接与叶片组件连接。当工作头需要安装在主体上时，仅需要将第二齿轮放置在布置在主体上的与第一档啮合的心轴上。这避免了将布置在第二齿轮上的偏心构件与上下刀片逐一对准和配合，从而提供了一种组装过程，该组装过程在提供可靠的连接的同时是简单和省时的。
