Abstract:
The invention relates to a screwing tool that comprises a drive arranged in a housing and an output shaft connected to said drive, a screwdriver point being arranged at the front face of the output shaft. The aim of the invention is to provide a screwing tool with which different connecting elements, in particular actuating and clamping elements consisting of a screwable sleeve and an inner screw can be screwed with only a single screwing tool. In order to achieve this aim, the screwing tool comprises a receiving part (500) which surrounds the output shaft and is displaceably guided in the direction of the axis (202) of the output shaft (200) against the force of a return element (505). Furthermore, an annular screwing tool (400), which surrounds the output shaft (200) and the screwdriver point (201), is rotatably mounted on the receiving part (500) for detecting the drive contours (305) of the peripheral surface (304) of a connecting element (303), at least one shiftable clutch (600) being arranged between the rotatably mounted annular screwing tool (400) and the output shaft (200).
