    摘要： AN AUTOMATIC SCREWDRIVER HAVING A HEAD WITH A MOVABLE SECTION WHICH IS NORMALLY RETRACTED SO THAT THE SCREWDRIVER BLADE IS RESILIENTLY URGED AGAINST A SCREW LOCATED IN THE SCREWDRIVER AND HAVING MEANS FOR MOVING THE MOVABLE SECTION FORWARD TO ALLOW THE FEEDING OF A SCREW INTO THE HEAD AND THEREAFTER RETRACTING THE MOVABLE SECTION. URGING THE SCREWDRIVER BLADE RESILIENTLY AGAINST THE HEAD OF THE SCREW PREVENTS THE SCREW FROM BACKING UP IN THE HEAD WHEN IT IS APPLIED TO A WORKPIECE. PNEUMATIC PRESSURE IS USED TO MOVE THE MOVABLE SECTION OF THE HEAD FORWARD.
