Claims

[Claims for Utility Model Registration] A driver bit that rotates in response to rotation from a motor is arranged in the driver body, and a suction sleeve having a suction mechanism is arranged around this dry eight bit to suck the driver bit. It is configured to be movable relative to the sleeve, and a chuck unit is attached to the tip of the driver body, while a piston part is arranged within the driver body so that it can freely move back and forth, and the suction sleeve and driver bit are moved as the piston part moves. In a suction type screw tightening tool configured to move together, a screw supply switch and a motor l switch are arranged on the driver body, and when the screw supply switch is turned on, the screw is supplied to the chuck unit and the piston part moves forward. A suction type screw tightening tool characterized in that the suction type screw tightening tool is configured to supply air so as to cause the screw to tighten, and to stop the air supply and suction when the motor drive switch is not turned on within a predetermined time after the screw supply switch is turned on.
