Torque wrench with an indicator mechanism, adjustment mechanism, and a signaling mechanism for signaling to a remote device when a torque to be applied has been reached

摘要

Torque wrench with an indicator mechanism (7) that has an adjustable indicator resistance that is set so the tool holder applies a specified torque. The resistance is set with an adjustment mechanism (15), while a transmitter transmits a signal to a receiver when the set torque is reached. A coding device (21) is provided to generate a signal when the adjustment value is reached.
