Claims

[Scope of utility model registration request]

It consists of a main body that incorporates an electric motor and a power transmission mechanism to which the output shaft of the electric motor is connected, and an outer sleeve and an inner sleeve that are attached to the front of the main body and to which the driving force of the electric motor is transmitted via the power transmission mechanism. A bolt tightening machine that fits the tip of the outer sleeve into the nut, fits the tip of the inner sleeve into the tip of the Torsia bolt, rotates the outer sleeve and the inner sleeve in relatively opposite directions, and fastens the Torsia bolt. , a temporary tightening sleeve having a built-in torque limiting mechanism that does not transmit torque exceeding the temporary tightening torque to the Torsia bolt;
The sleeve for final tightening which does not have the above-mentioned torque limiting mechanism,
A bolt tightening machine characterized in that either the outer sleeve or the inner sleeve is attached to the main body interchangeably.
