Turn angle indicator for torque spanner can be coupled to spanner and displays angle by digital roller mechanism driven by spanner

摘要

The turn angle indicator (1) can be used with a torque spanner (3) to display the angle. The device can be coupled, at least indirectly, to the torque spanner. The angle is displayed by a digital roller mechanism driven by the tool. The digital roller mechanism may be connected to the spanner via a transmission in a housing containing a rotatable drive element.
