The link cannot be moved after it is attached and detached to a static model

I use https://github.com/Pitrified/gazebo_r... to attach my robot‘s tail link to ground_plane's link,but the head link cannot be moved after it is detached from the ground_plane's link. Not native English Speaker，Thanks！

The head link appear to be fixed at the joint points.

not fix,but a trick can "fix it",just attach a box to ground_plane then attach your model to the box.
