Claims

[Claims for Utility Model Registration] A driver bit that rotates in response to the rotation of a motor and a guide sleeve arranged around the driver bit so as to be relatively movable,
In a screw tightening unit configured to lower these together by the operation of a cylinder and to attract a screw to the tip of a driver bit, an air supply source is connected to the first supply/discharge port of the cylinder via a pressure reducing valve. A driver that connects the driver bit, sets the pressing force of the cylinder in the direction in which the driver bit descends to a small value, and directly connects the drive shaft of the motor and the driver bit via a connector so that they reciprocate together, and further holds the motor. while arranging the sensor so as to move with the base, the guide three is biased by a spring so as to be retractable with respect to the driver base;
The screw lifting detection device is characterized in that a dog that moves with the movement of the guide sleeve is arranged at a predetermined distance from the sensor, and the movement of the dog is detected by the sensor.
