A breaking torque wrench (2) comprises a head portion 8 pivotally connected to a main tubular body (4) and a breaking mechanism (10) comprising a first part (22) and a second part (24) which have a movable point of mutual contact, wherein the first part (22) is connected to the head portion 8 and the second part 24 is resiliently urged into contact with the first part (22), such that when the torque wrench (2) is used to apply a predetermined torque, the first part (22) moves relative to the second part (25), allowing the head portion (8) to pivot about the main tubular body (4) of the torque wrench and the second part 24 to move relative to the main tubular body (4). |
