摘要： A hammer drill for manually guided operation includes an electric drive motor, a tool spindle and a pneumatic hammer function. The hammer drill includes a pressure piston, a striker, and a beat piece for striking axially against a tool that is held by the tool spindle. When the striker reaches a forward limit position, an end section thereof protrudes into a retaining ring that is aligned coaxially with the spindle axis. Manufacturing quality can be improved by bracing the retaining ring against an annular collar in the tool spindle on the one side and axially against a locking ring set in an annular groove conformed in the tool spindle via a retaining disc on the other side. The retaining ring, the retaining disc and the non-return disc are each mirror-symmetrical.
摘要翻译：用于手动引导操作的锤钻包括电驱动马达，工具主轴和气锤功能。锤钻包括压力活塞，撞针和用于与工具主轴保持的工具轴向冲击的打击片。当撞针到达前进极限位置时，其端部突出成与主轴轴线同轴对准的保持环。通过将保持环支撑在一侧的工具主轴中的环形环上并且通过另一侧上的保持盘轴向抵靠设置在工具主轴中的环形槽中的锁定环，从而可以提高制造质量。保持环，固定盘和止回盘均为镜面对称的。

摘要： An auxiliary handle for a hand-held power tool has a handle part gripped by a hand of an operator and defining an axial direction. An attachment part with which the auxiliary handle is to be attached to a power tool is provided. An elastic damping element connects the handle part and the attachment part, wherein the handle part is secured to the attachment part by positive fit. A unitary holding section is connected to the handle part or the attachment part and a unitary securing section is connected to the attachment part or the handle part. The holding section surrounds with lateral play in all directions the securing section on all sides so that a damping space is generated between the securing section and the holding section. The damping element fills out the damping space at least partially.
摘要翻译：用于手持式电动工具的辅助手柄具有由操作者的手夹持的手柄部分并且限定轴向方向。提供将辅助手柄附接到动力工具的附接部件。弹性阻尼元件连接把手部分和附接部分，其中手柄部分通过正配合固定到附接部分。一体式保持部与手柄部或连接部连结，整体式固定部与安装部或手柄部连接。保持部围绕着所有方向的侧向游动，在固定部和保持部之间产生阻尼空间。阻尼元件至少部分填充阻尼空间。
