A torque structure includes a first body, a first strain gauge, a second strain gauge, and a second body unit. The first body is provided with a first receiving groove. The first strain gauge detects a bending strain of t he first body. The second strain gauge detects a torque deformation amount of the first body. The second body unit includes a second body, an indicator, a housing, and a power supply member. The second body is provided with a second receiving groove and a slot. The indicator is mounted in the slot and provided with a switch, a first push button, and a second push button. The indicator is electrically connected with the first strain gauge and the second strain gauge. The housing and the power supply member are received in the second receiving groove.
