Abstract
A power tool attachment part for a power tool, comprising: an elongate housing including an upper housing part and a lower housing part interconnected with the upper housing part. An input gear is configured to be connected to an output shaft of a power wrench, which input gear is arranged at a first end of the housing. An output gear has an output interface. The output gear is arranged at a second end of the housing. A first intermediate gear is arranged inside the housing and configured to transmit torque of the input gear to the output gear. The first intermediate gear is rotationally mounted on a first intermediate gear shaft. A torque sensor is configured to measure radial forces acting on the first intermediate gear shaft to thereby obtain a measure of the torque at the output gear.

A power tool attachment part for a power tool, comprising:
- an elongate housing including an upper housing part and a lower housing part interconnected with the upper housing part;
- an input gear configured to be connected to an output shaft of a power wrench, which input gear is arranged at a first end of the housing;
- an output gear with an output interface, which output gear is arranged at a second end of the housing;
- a first intermediate gear arranged inside the housing and configured to transmit torque of the input gear to the output gear, which first intermediate gear is rotationally mounted on a first intermediate gear shaft;
- a torque sensor configured to detect radial forces acting on the first intermediate gear shaft to thereby obtain a measure of the torque at the output gear, wherein the torque sensor comprises a piezo-electric element or a strain gauge;
- and
- an electronics unit configured to receive measurements from the torque sensor and transmits the measurements to a control unit associated with and configured to remotely control operation of the power tool.
