It looks like you have screwed a freewheel onto a uniglide hub?
If you can grip the cassette hub splines with some slip jaw (water pump) pliers maybe you could unscrew the freewheel with the correct tool inserted in the end…?
That hub takes a cassette, not a freewheel. I would go to a shop before you permanently damage something

It looks like you were trying to fit a screw-on *freewheel* to a freehub that should take a *cassette* instead. [That was never going to work](https://www.sheldonbrown.com/free-k7.html), and it’s quite possible that you’ve damaged both the freewheel and the freehub body now. A pin spanner will help you disassemble the freewheel, but won’t help you get it off the hub.
I suggest right now that you stop trying to force the freewheel off, sit back, have a cup of tea or whatever it is you usually do to relax, then do some research about what your next step will be. Maybe you can get the freewheel off, and the freehub splines are still OK – in this case you can buy the correct cassette and fit it. Maybe the freewheel is permanently stuck there, but you can take the freehub body off and replace it. This might be a job for a bike shop if you’re not confident with rebuilding hubs. Good luck!
You’re mixing incompatible standards here. I’d recommend going to your friendly LBS and letting them handle this for you.
You have managed to somehow install a freewheel on to a freehub. Remarkable actually. I wouldn’t have believed it was possible! And broke your tool. Congrats. Do first, think later.
Everything you did here is wrong and I am not sure how to answer your “question”. You have ruined all these components and will need to replace them.
Your hub is meant to accept a cassette, not a freewheel.
A cassette is a stack of individual gears that mesh with the splined ratcheting mechanism integrated into the hub, and secured with a lockring. A freewheel, on the other hand, is one unit that combines the gears and ratcheting mechanism, and it threads directly into the hub.
To remove the freewheel, you’ll want to pick up a freewheel removal tool, such as the Park tool FR-1.3. Make sure to get one that is compatible. It fits into the interior splines and allows you to use a wrench. Sorry that people are being rather rude to you.
