Abstract: A torque-indicating extensive apparatus includes an extensive rod, two sensors and a display unit. The extensive rod includes a first engaging section for engagement with a handle, a second engaging section for engagement with a bit, a middle section extending between the first and second engaging sections, and a waist formed on the middle section. The size of the waist is larger than that of the second engagement section so that stress is not concentrated in the waist when torque is transmitted through the extensive rod. The sensors are attached to the waist. The display unit is electrically connected to the sensors.
