ABSTRACT:
A detent structure of a torque wrench for adjusting operation angle thereof, including a wrench handle, two detents, a resilient member and a working head. One end of the wrench handle is formed with a pivot cavity. Via the resilient member, the detents are movably disposed in the pivot cavity of the wrench handle. One end of each detent is formed with an engaging section having a connecting channel. The other end of each detent has a pres section. Two ends of the resilient member are formed with two connecting sections inserted in the connecting channels of the detents. One end of the working head has an engaging section pivotally disposed in the pivot cavity of the wrench handle. The engaging sections of the detents are engaged with the engaging section of the working head. By means of the resilient member disposed between the detents, a user can press the press sections of the detents with little strength to disengage the engaging sections of the detents from the engaging section of the working head. Under such circumstance, the working head can be easily pivoted to adjust operation angle.
