Electric driver tool for synthetic resin screw

Abstract

To suction a screw by a negative pressure to correct an attitude of the screw to a normal attitude and hold the screw.SOLUTION: A driver bit 16 is enclosed through a space 22 by a cylindrical suction cylinder 21. A negative pressure is formed in the space 22 through a suction passage 24 by an ejector mechanism. A pointed end part 17 of the driver bit 16 protrudes to the outer side of an end 27 of the suction cylinder 21 slightly. The negative pressure is created in the space 22 to generate airflow A flowing from the lower side to the upper side near the pointed end part 17. When a screw B is suctioned by the airflow A and the pointed end part 17 contacts with a head H of the screw B, the screw B is pushed up at the head H and concurrently corrected to a substantially normal attitude with the pointed end part 17 set as a supporting point. Then, a plus groove of the screw B is fitted in the pointed end part 17.SELECTED DRAWING: Figure 3
