As explained above, according to the present invention, after positioning the hooking portion of the coupling member on the guide portion of the coupled member, the rotating arm is rotated by the drive mechanism, so that the hooking portion of the hooking portion is rotated. The coupling member engages with the engaging portion of the movable arm, pulls in the coupled member, and pushes it out to release the coupling, so the coupling can be performed without positioning the coupled side and the coupled side with high precision. It has the advantage that it can be uncoupled, it can be firmly coupled, and it can also be used as a gripping device.
