    • A dust-intercepting member is so mounted on a hand-held power tool as to contact a structure being acted upon around the tool element of the power tool, by a mounting arrangement which includes two hollow elongated mounting members one of which is received within the other for telescoping relative thereto while being retained against rotation with respect to the other mounting member about the common axis of the mounting members, and a helical compression spring the ends of which are respectively received in the interiors of the mounting members and urge the latter in opposite directions. The other mounting member is attached to an auxiliary hand grip which, in turn, is mounted on a cylindrical extension of the housing by a quick-release clamping arrangement. A setting ring on the inner one of the mounting members determines the depth of penetration of the tool element into the structure. A depth-determining profiled rod is displaceably and arrestably mounted on the auxiliary hand grip. The outer one of the mounting members is connected to the profiled rod when the intercepting arrangement is mounted on the auxiliary hand grip.
    • 防尘构件安装在手持式电动工具上,以便通过包括两个中空的细长安装构件的安装装置接触作用在电动工具的工具元件周围的结构,其中一个被接纳在电动工具的内部 另一个用于相对于其伸缩,同时相对于另一个安装构件相对于安装构件的公共轴线保持抵抗旋转;以及螺旋压缩弹簧,其端部分别容纳在安装构件的内部并将其推入 相反的方向 另一个安装构件附接到辅助手柄,辅助手柄又通过快速释放夹紧装置安装在壳体的圆柱形延伸部上。 在安装构件的内部的设置环确定工具元件进入结构的穿透深度。 深度确定的成型杆可移动和可阻止地安装在辅助手柄上。 当拦截装置安装在辅助手柄上时,外部安装构件连接到成型杆。
