Pivot points to test different states of model

Hey there, I would love to attach different pieces of my model together on Different pivot points, so I can test like extended and retracted states.
At the moment I have to move and tilt every part on its own to check differences and that takes up a lot of time when there is a lot of geometry involved.

Like in the Pictures!


Thanks for the help.

You can use translate or align tool. That would be a easy way.
