摘要： The invention relates to a portable handheld tool such as a motor chain saw, cutoff machine or the like having a motor arranged in a housing. The motor drives a work tool via a drive pinion. The portable, handheld tool is provided with a handle arrangement for holding and guiding the tool with the handle arangement being decoupled from the motor system by antivibration elements. Soft antivibration elements are required to obtain high isolation; whereas, the antivibration elements have to be as stiff as possible in order to reliably guide and hold the handheld tool. The antivibration elements holding the handle arrangement on the side of the drive pinion are arranged to lie approximately in a common plane. This arrangement makes it possible to use softer antivibration elements without the required stiffness for guiding and holding becoming too low.

摘要翻译： 本发明涉及一种便携式手持工具，例如具有布置在壳体中的电机的电动链锯，切断机等。 电机通过驱动小齿轮驱动作业工具。 便携式手持式工具设置有用于保持和引导工具的把手装置，其中手柄布置通过防振元件与电动机系统分离。 需要软的抗振元件才能获得高隔离度; 而为了可靠地引导和保持手持式工具，防振元件必须尽可能的坚硬。 保持手柄装置在驱动小齿轮一侧的防振元件大致设置在公共平面上。 这种布置使得可以使用较软的防振元件，而不需要刚性用于引导和保持变得太低。
