Problem with neck - pictures

This is what I mean of inner bottom of the nut:

Inner bottom is what we don't see here, inner bottom is being hit by the rod when the nut cannot be screwed more clockwise.

How would you call this inner bottom in English in better way?
 
You need to stop. Take the washers out. You either have a dual action rod like the first rod picture you showed or the rod is broken at the anchor end.

If its dual action, the nut has broken away from the inner rod. Push the rod back into the neck. Put a small hex nut on the threads. Put the socket nut on and tighten the two nuts against each other so they are locked together (once they contact each other, use a wrench on the hex nut to reverse it as you tighten the socket nut against it). Loosen the nut, continue loosening and see resistance will begin: the rod will begin to bend the other direction and flatten the neck.

You see the threads at each end of the rod are reverse threaded to each other. Turn one way the ends are drawn together and the flat bar bends away from the round rod. The other way the ends push apart and the flat bar bends closer to the round rod.

You mean this way? turn the lower nut counterclockwise and the upper nut clockwise so they block the rod and turning any of them will turn the rod?

the upper nut will be the regulation nut. how can I say 100% that the rod at the opposite side has broken from the opposite side nut?
 
Yes like that. Although I have thought about it all day and don't think you have a dual. rod. Sorry if i have misled you. You posted a picture of a dual and had me thinking you do have one. But there is no evidence of a weld on the nut or threads. But it's worth a try and see what happens.

If your rod is standard and broken at the head end, it would turn quite easily. Put a mark on the rod and see if it rotates when you tighten.

Yes I put dual rod pictures not mentioning that I have one. What standard rod look like/work like?
