Abstract
A pneumatic driven wrench comprises: a housing defining a middle channel; a cylinder defining two fluid passages; a rotor; a first valve; a second valve driven by a valve-switching member for controlling fluid communication between the middle channel and a selected one of the fluid passages; a valve-triggering unit for driving the first valve; and a locking member driven by the valve-triggering unit to move between releasing and locking positions. The locking member engages one of the valve-switching member and the second valve when at the locking position. The locking member is disengaged from the one of the valve-switching member and the second valve when at the releasing position.
