Abstract
A setting torque tool to tighten a screw or a similar fastener to a target torque is disclosed. The torque tool comprises a main body with a housing and a drive shaft, which is firmly attached to the housing to transfer a torque. The drive shaft has a connection area, to which a drive can be connected. An adapter for an operating tool rotates together with the housing and the drive shaft to transfer the torque, Sensor measure and evaluate the torque transferred. A release mechanism, which is arranged in the housing, releases the torque tool upon reaching a target torque.

-14. (canceled)
A torque tool (10, 110, 310, 410) which releases at a target torque for tightening screws and similar fasteners, comprising:
- a main body (12, 112, 312, 412) with a housing (14, 114, 314, 414) which rotate around a common axis to transfer a torque;
- a drive shaft (18, 118, 218, 318) firmly connected with the housing (14, 114, 314, 414) to transfer the torque;
- a connection area (27, 127, 327) on the drive shaft (18, 118, 318) configured to connect to a drive;
- an adapter (30, 130, 330) for an operating tool, which is provided on the main body (12, 112, 312, 412) and rotates together with the housing (14, 114, 314, 414) and the drive shaft (18, 118, 318) to transfer the torque;
- a sensor (74, 174, 374) to measure and evaluate the torque transferred;
- and
- a release mechanism (44, 144, 344, 444) which is arranged in the housing (14, 114, 314, 414) and which releases upon reaching a target torque,
- wherein the adapter (30, 130, 330) for the operating tool is pivot-mounted in the housing (14, 114, 314, 414), and
- wherein the release mechanism (44, 144, 344, 444) contains a locking mechanism (46, 146, 346, 446), which connects the adapter (30, 130, 330) to the housing (14, 114, 314, 414) to transfer the torque and unlock when the release mechanism (44, 144, 344, 444) is released to allow said adapter to rotate freely in the housing (14, 114, 314, 414).
