Improvements in the mechanisms of rock drills, which in combination with a motor suitable to act with a pressurized air supply device located in a box, comprise a working cylinder for compressed air, a moving member inside said cylinder, under the pressure of air, a cylinder head next to the box, a cylindrical main control valve rotatable in a first cylindrical bore made in the cylinder head with its axis practically parallel to the axis of the working cylinder and arranged to control the compressed air that a rotary cylindrical auxiliary valve is sent to the work cylinder in a second cylindrical bore made in the cylinder head with its axis practically parallel to the axis of the working cylinder and arranged to control the compressed air of the feeding device, handles for actuating said valves, and a handle on the cylinder head located transversely to the cylinder axis work and placed next to said handles so that a hand that grips the handle can trigger the repeated handles without releasing it.
