A pneumatically operated driving tool having an improved release locking function having a working cylinder, a drive-in tappet mounted on the working piston, a control valve array for moving the piston to the lower dead center and to the upper dead center, and a piston return chamber which is connected to the working cylinder via a first opening adjacent to the lower dead center and via a second opening spaced apart from the lower dead center. The driving tool further includes a mouth tool having a drive-in channel, a magazine having an opening adjacent to the mouth tool, a sensor comprising a slidable sensor head, a sensor slide portion connected to the sensor head and an abutment portion extending transversely to the sensor slide portion's direction of displacement. The driving tool further includes a trigger lever for displacing the valve rod, having a pivotally mounted valve lever as well as a control lever mounted thereon, wherein the free end of the control lever end is supported by the abutment portion before actuation of the sensor and before actuation of the trigger lever, and wherein the control lever end remains supported by the abutment portion after actuating the sensor. When the trigger lever is actuated, so that the control lever actuates the valve rod, the free end of the control lever slips from the abutment portion until the sensor, which locks when actuating the valve rod and unlocks when releasing the valve rod, is reactivated so that the valve rod is not further displaced by the trigger lever.
