I found this today - have no idea what it is or what it does. Anyone?

I have no idea how this thing works - i believe it's broken. The bottom shaft with the holes turns and I hear and feel the gears inside the unit working, but none of the other shafts turn, extend, or move at all. And it's heavy.
