摘要

The invention relates to a torque wrench (1) as a power wrench, with a drive motor (13) with an intermediate gear (16) connected downstream of the drive motor (13) and with a helical gear (5) connected downstream of the intermediate gear (16) as a planetary gear with an output-side screwing tool part (10) ), and with a housing (2) with at least one handle (3) in which the drive motor (13) and the intermediate gear (16) are arranged in sequence. According to the invention, the drive motor (13) is arranged and fixed in a rotationally fixed manner in the housing (2) and the intermediate gear (16) is rotatably mounted in the housing (2) and connected in a rotationally fixed manner to a ring gear (24) of the planetary gear, so that during a screwing operation by an operator only the reaction forces occurring on the housing (2) by the drive motor (13) need to be supported and the reaction forces occurring through the intermediate gear (16) are also supported with the torque support foot (7).
