The fixing portion 51 has an amount. The measuring member 54 extends from the fixing portion 51. In use, the dentist combines an artificial root (not shown) with the working portion 52, and then holds the trigger portion 53 to rotate, so that the operator can then adjust the measurement when the trigger portion 53 is rotated. The torque of the piece 54 is marked to obtain the torque of the current output. When the triggering portion 53 is aligned with the predetermined torque indicating value of the measuring member 54, it represents that the operator has turned to achieve the predetermined torque value, that is, stops rotating.
