'penguin' is the definition.
I know nothing about this answer so I can't judge whether this works.

'pinch star parts' is the wordplay.
'parts' indicates an anagram (the parts of the original word ordered differently).
'pinch'+'star'='pinchstar'
'pinchstar' anagrammed gives 'CHINSTRAP'.

'of' is the link.

Can you help me to learn more?

(Other definitions for chinstrap that I've seen before include "securing device" , "This secures cover for head" , "hat" , "Bit of helmet" , "Band" .)

I've seen this clue in the Sydney Morning Herald.
