摘要： A setting tool for screwing a threaded rod into a receiving material includes a work driver formed by a sleeve-like member. A retainer part is secured within one end of the sleeve-like member for holding the threaded rod while it is inserted. The end of the threaded rod located in the retainer part bears against a piston positioned within the sleeve-like member. A hydraulic medium holds the piston against the end of the threaded rod so that the rod is held in the work driver. After a threaded rod has been set, the rod can be removed from the retainer part by relieving the pressure of the hydraulic medium acting on the piston. The pressure is built-up as the threaded rod is screwed into the receiving material. The pressure is released by opening a valve connected to the space in the sleeve-like member containing the piston and hydraulic medium.

摘要： A setting tool for screwing threaded rods into a base material includes a receiving member (I) with a threaded bore (2) extending axially through it. The receiving member (1) is positioned in a blind bore (4) of an entrainment member (3). Receiving member (1) is axially displaceable relative to the entrainment member (3) by means of a ball thread spindle (6). The axial displacement of the receiving member (1) in the blind bore (4) is limited by a stop (5) and by an annular disk-shaped closure element (8). The threaded rod can extend through the closure element (8) into the threaded bore (2). The engagement of the threaded rods with the stop (5) can be released in a simple manner after the completion of the screwing-in procedure.
摘要翻译：用于将螺杆拧入基材的定位工具包括具有轴向延伸通过其的螺纹孔（2）的接收构件（I）。接收构件（1）定位在夹带构件（3）的盲孔（4）中。接收构件（1）通过滚珠丝杠（6）相对于夹带构件（3）可轴向移动。接收构件（1）在盲孔（4）中的轴向位移由止动件（5）和环形盘形封闭元件（8）限制。螺纹杆可以延伸通过封闭元件（8）进入螺纹孔（2）。螺纹杆与止动件（5）的接合可以在螺纹拧紧过程完成之后以简单的方式释放。
