I wonder what this phrase means here.
Nothing is gonna keep you from getting what you deserve, not if I can help it.

He's not riding on the back of that motorcycle, not if I can help it.
She won't be invited again, not if I can help it
I wonder what the phrase "not if I can help it" means here.
Please could I trouble you, asking you of explaining the meaning of that phrase in each sentence to me?
Please help me!
