    • A motor unit has a tool for engaging a work piece with a frame unit, which has a gripping element for the handheld operation of the device, wherein a mechanical coupling is provided between the motor unit and frame unit, which encompasses at least one dampening element, in such a way that makes it possible to precisely guide the tool while improving the dampening of vibrations between the motor unit and frame unit. The frame unit has at least one abutting element, against which the motor unit abuts when a working force exerted by the work piece on the tool has a value below a minimum value.
    • 马达单元具有用于将工件与框架单元接合的工具,所述框架单元具有用于装置的手持操作的夹紧元件,其中在所述马达单元和框架单元之间设置有机械联接件,所述机构联接件包括至少一个阻尼元件 ,使得可以精确地引导工具,同时改善电动机单元和框架单元之间的振动的衰减。 框架单元具有至少一个邻接元件,当由工件施加在工具上的作用力具有低于最小值的值时,马达单元抵靠该邻接元件。
