摘要： A lawn cutting device includes a handle having a hollow connecting part that has a bottom end portion defining a bottom opening and a driving member having an output shaft that is received in the connecting part of the handle and that extends outwardly through the bottom opening. The device also includes a blade-mounting seat spaced apart from the bottom end portion of the connecting part of the handle, and aligned coaxially with and secured to the output shaft. The device further includes a blade member mounted on the blade-mounting seat; and a protecting member including a cup-shaped body that is coaxially aligned with and that extends from the blade-mounting seat, and that defines a recess which receives the bottom end portion of the connecting part of the handle therein.

摘要： A power tool includes a housing, a battery-operated power supplying unit, a driving unit, and a battery status indicator. The power supplying unit is mounted in the housing, is adapted to be connected to a battery unit, and includes a processor unit capable of monitoring status of the battery unit. The driving unit is mounted in the housing, is adapted to be coupled to a tool bit, and is coupled electrically to the power supplying unit. The processor unit controls drive operation of the driving unit. The battery status indicator is mounted to the housing, is coupled electrically to the power supplying unit, and is controlled by the processor unit to generate a light output visible externally of the housing for visually indicating the status of the battery unit as monitored by the processor unit.
摘要翻译：电动工具包括壳体，电池供电单元，驱动单元和电池状态指示器。供电单元安装在壳体中，适于连接到电池单元，并且包括能够监视电池单元的状态的处理器单元。驱动单元安装在壳体中，适于联接到工具头，并且电连接到供电单元。处理器单元控制驱动单元的驱动操作。电池状态指示器安装到壳体，电耦合到电力供应单元，并且由处理器单元控制，以产生在壳体外部可见的光输出，用于可视地指示由处理器监视的电池单元的状态单元。
