Abstract
PURPOSE: To forcibly removing a screw from a band, and to automatically thread the screw into a work material by connecting a lower end of a motor portion of an air motor and a lower part of a sub piston to each other for fixation, and integrally arranging the motor portion and the sub piston freely to be moved in the vertical direction. CONSTITUTION: A trigger 11 is pulled so that a valve 16 takes the compressed air inside of an air reservoir chamber 41 through an intake hole 33 of a motor portion 20, and an air motor 18 is driven so as to rotate a bit 1. At the same time, an intake passage 13 is connected to a discharge passage 15, and the air inside of the valve chamber 41 and a sub cylinder 50 is opened to the atmospheric air, and a head valve 36 is pushed up by the compressed air inside of the air reservoir chamber 40 so as to cut off the communication of the inside of the cylinder 26 with the atmospheric air. On the other hand, compressed air inside of the air reservoir chambers 40, 22, 14 is supplied in a sub cylinder 53 through a cylinder 26, and the motor portion 20 and the sub piston 61 are integrally pushed down with each other, and the bit 1 is lowered while it is rotated, and a screw 3 is lowered by a tip of the bit 1 so as to be removed from the band 19, and threaded into the work material 7, 10.
