I don't know when you got him, or how much you handle him.
You should keep handling him until he gets used to you. If you're afraid of him striking, then wear gloves, socks, etc. on your hands. If he does bite you, the first time is always the scariest, but it doesn't hurt, so just be persistent. Short periods of holding, everyday can help I think.
You can use a hook or hanger to move him if you're really nervous, but it won't help your snake adjust to you picking him up. Maybe if you use a hanger/hook to get him out of his cage, then hold him, rather than reaching in, he'll be less likely to strike? That's just a guess. I don't know. Someone else could probably help you more.
Be persistent though!
