A rotatable handle arrangement for a torque-adjustable wrench including a hollow sleeve fixed at a distal end of the moment arm by a fixing element. An internal toothed portion is formed in a stepped hole of the hollow sleeve and positioned adjacent to one side of the in-place-rotatable handle. In the normal state, the internal toothed portion is engaged with an external toothed portion of the in-place-rotatable handle by means of an elastic element. The torque-adjustable rod of a torque adjusting mechanism is driven by the in-place-rotatable handle for adjusting the torque value when the in-place-rotatable handle is pushed in the direction of the hollow sleeve so as to disengage the internal and external toothed portions from each other. In this way, an expected adjustment is achieved. After the adjustment, the external force is released and the internal and external toothed portions are automatically restored in an engaged and locked position (of the normal state) by means of the self-resilience of the elastic element.
