A torque wrench has a force-applying rod. The force-applying rod is connected to a transmission rod. The transmission rod can swing relative to the force-applying rod. A transmission shaft is disposed in the transmission rod. Two ends of the transmission shaft are connected to a drive unit and a drive unit, respectively. A trip unit and an adjustment unit are disposed between the force-applying rod and the transmission rod. The adjustment unit has a main scale ring, an adjustment ring, and a secondary scale ring. The drive unit is first started to tighten a workpiece in place quickly, and then the workpiece is further tightened manually. The workpiece can be locked quickly and accurately with a constant torque. The positions of the main scale ring and the secondary scale ring can be adjusted to correct the torque value.
