1. A pneumatic tool comprising:
a main chamber configured to reserve compressed air supplied from an air source;
a drive mechanism configured to drive by an air pressure of the compressed air by the compressed air reserved in the main chamber being supplied;
a head valve having a first chamber configured to reserve the compressed air that is supplied from the air source, and configured to be actuated depending on pressure fluctuation in the first chamber to allow the compressed air to be supplied from the main chamber to the drive mechanism;
a trigger valve configured to actuate the head valve by exhausting the compressed air in the first chamber; and
a control valve configured to disable exhaustion of the compressed air of the first chamber by the trigger valve.
