Looking at the picture I think the control lever assembly can be bend back if the metal is not broken.
Those control lever assemblies are made of thick gauge metal.
Is hard to tell from the picture if is only bent.
Like Paul said the collar is probably seized. So you need a new 9mm head.
If memory serves well I think I have a brand new 9mm head that I don't need any more ( I have to look for it) that works with that pump. If you want it let me know.
But you need to remove the rotor head from the pump. Not an easy task... Too many parts that can fall off.
I would remove the control lever assembly and see if you can straight it out and then you will need a new 9 mm head.
Please let us know what you find once you remove the control lever assembly.
We love pictures
