The invention relates to a power tool, in particular a pipe press, comprising a drive, an output shaft, a threaded spindle drive and a linear actuator, the torque generated by the drive being transmittable to the linear actuator via the output shaft and the threaded spindle drive connected to the output shaft. The power tool comprises an eccentric transmission for torque adjustment between the drive and the threaded spindle drive, where the eccentric transmission comprises a drive eccentric drivable by the drive, an eccentric gear drivable by the drive eccentric, and a compensation coupling, the compensation coupling is drivable by the eccentric gear and is used to transfer torque from the eccentric gear to the output shaft. 本发明涉及一种动力工具、特别是管压机，包括驱动器、输出轴、螺纹主轴驱动器和线性致动器，其中，由该驱动器产生的扭矩能够经由该输出轴和连接到该输出轴的该螺纹主轴驱动器传递到该线性致动器。该动力工具包括用于在该驱动器与该螺纹主轴驱动器之间进行扭矩调节的偏心传动装置，其中，该偏心传动装置包括能够由该驱动器驱动的驱动偏心件、能够由该驱动偏心件驱动的偏心齿轮、以及补偿联接器，该补偿联接器能够由该偏心齿轮驱动并且用于将扭矩从该偏心齿轮传递到该输出轴。
