You have TWO bends to address. They are indicated by the red arrows.
The handle end is the most fragile part of this.
The Blue arrow shows where the pin is that holds it in place.
This pin is usually tapered so it only comes out one way.
If you do not have a pin punch set an old nail with the point filed down to a flat can be gently tapped to drive the pin out. then you will have access to the handle without risking the fragile cast iron body of the handcrank.
Once removed you can support it where the long thick green arrow is and GENTLY tap the opposite side (where the other thick green arrow is) to straighten it.
A few taps are better than one big whack.
