The torque wrench 30 includes a shank 40 having a drive head 42 at a front end and two pivoted ends (45, 47, Figure 5) at a rear end. A front end of a connection rod 50 is pivotally connected with the first pivoted end. A housing 60 includes a tubular body 61 and a casing 65 fixedly disposed on one side of the tubular body. The connection rod is relatively slidably fitted in the tubular body. A torque adjustment mechanism includes a fixing block (70, Figure 5) mounted in the tubular body by at least two pins 75. A stop member 80 is received in the casing with a front end pivotally connected with the second pivoted end of the shank. The stop member is angularly displaceable within the casing. The fixing block may be easily demounted from the tubular body for replacement. An alternative torque wrench includes a branch bar, a sandwich pivot structure with two lugs, a collar and at least one pin member. |
