When the flange(41) located on both side of the lower part of the adapter(40) descends perpendicularly down to the upper end of the lever(20), the slot(42) enters the inside(21) of the lever(20). As the tool adapter(40) continues descending, the lever(20) turns round on the pin(22) guiding the lower flange(41). At this time, because the ball(31) is applying the pressure by the force of the spring, when the lever completes the rotation, the tool adapter(40) is fixed at the designated position and the safe arrival of the adapter is recognized by the sensor(60).
