How come blood vessels and nerves are not pinched when we bend our elbows/knees and other bend parts?

*Bendy parts. Sorry for title typo.

Well, depends on how you define pinched. They aren't really pinched because they aren't in the joint barring major trauma.  They can, however, have slight pressure on them at maximal flexion (particularly if you are a bit big) that you would experience as "pins and needles" and eventually pain over time.  That would be those in front of the joint. Those passing behind could be put on slight stretch with the same symptoms. Other neurovascular structures pass beside the joints and don't care that much about flexion usually.
