Claims

[Scope of utility model registration request]

The upper arm, which has a worm for the upper arm driven via a shaft and bevel gear that transmits the rotational force from the motor, is placed on the top of the tightening tool body, and can be moved up and down through a slide hole at the bottom of the main body. A lower arm that slides as the moving shaft rotates is disposed facing each other, and an electric tightening tool equipped with an independent lower arm worm is attached to the lower arm, and an electric tightening tool is attached to the center of the disk. A nut fitting hole that matches the outer shape of the nut is drilled, and a worm wheel is carved on the outer peripheral surface of the disk to engage with both upper and lower worms mounted on the upper and lower arms of the electric tightening tool. A power tool for high-speed nut tightening that is combined with a tightening jig that has a positioning plate facing the nut fitting hole.
