Claims

[Scope of utility model registration request]

In a multi-axis tightening device that simultaneously tightens a plurality of objects to be tightened by sockets connected to a plurality of drive units each having a fluid motor driven by a fluid supplied from a fluid source, a predetermined one of the plurality of drive units The fluid motor of the unit is connected to the fluid source via a switching valve that can be switched to a cutoff position to stop only the fluid motor of the predetermined unit while driving the remaining fluid motors, and the output of the predetermined unit is The socket connected to the shaft is connected to a first joint that is connected to the output shaft of the drive unit and rotates together with the fluid motor, and a first joint that is connected to the second joint via an elastic body. The fastened joint is expandable and retractable along the axial direction of the joint by or against the elastic force of the elastic body, and the rotational force of the drive unit is transmitted through the first joint. A multi-axis tightening device comprising: a second joint formed with a socket portion that fits into an accessory.
