ABSTRACT:
A screw driving and turning machine comprises: a body having a nose portion; a driving cylinder received in the body; a screw driving mechanism having a driving piston having a driving and turning bit slidably accommodated in the driving cylinder, wherein compressed air is fed into the driving cylinder to drive the driving piston, and a screw held in the nose portion of the body is driven to a state in which a head portion of the screw is raised; a screw turning mechanism having an air motor driven by a portion of compressed air fed to the driving cylinder, for turning the screw, which has been driven by the driving piston; a stop valve for opening and closing an air passage between the driving cylinder and the air motor, arranged in the middle of the air passage; and a contact arm slidably arranged along the nose portion, for operating the stop valve by being pushed to the body in accordance with pressing an end of the contact arm against a material into which the screw is driven, wherein the feed of compressed air from the driving cylinder to the air motor is stopped by closing the stop valve when the contact arm is pushed to a predetermined position by pressing an end of the contact arm against the material into which the screw is driven.
