The function shaft has a head adapted to drive a workpiece and a connecting rod laterally extending from the head. The connecting rod is received in and engaged to one end of the handle. The function shaft has a torque sensor mounted in the connecting rod and electrically connected to the counter for sensing a torque value from the head, whereby the counter executes a weighted compute and shows date when receiving a signal from the torque sensor.
