Abstract
An input module for a torque wrench includes a hollow shank having a first end and a second end. A driving head is partially received in the first end of the hollow shank and has a driving stub laterally disposed thereon. A sensing unit is mounted in the driving head. A grip is disposed on the second end of the hollow shank. An input mechanism includes a display device, multiple rotary rings and a processing unit. The multiple rotary rings are co-axially and rotatably mounted on the outer periphery of the hollow shank adjacent to the grip and electrically connected to the processing unit for inputting an alarm torque value to the processing unit.
