置。 A device for screw connection consisting of a male screw and a female screw, which includes a driver bit that is directly fitted to the male screw, and a screwdriver bit that is directly connected to the driver bit or connected via a gear to rotate the driver bit at high speed. A first motor with low torque and low inertia, a one-way clutch directly connected to the driver bit, and a second motor with low speed and constant torque connected directly to the one-way clutch or through a gear, The first motor rotates and screws the male screw until the head bearing surface of the male screw seats on the upper surface of the object to be tightened, and then the rotational speed of the driver bit decreases due to the seating of the male screw. As the rotational speed of the second motor catches up, the one-way clutch locks, and the second motor
A screw tightening device characterized in that the motor backs up the first motor to turn the driver bit and tighten the male screw.
