That look like a square taper so a sqare taper extractor should do the trick. what extractor did you buy?

The ebay extractor tool looks like the right one.

Are you saying the black part of it won't screw into the crank?

You have backed the axtraction part out the body before trying to screw it in haven't you, that one should do the business.

the middle bolt that you crew into the crank is too big for the axle its screwing into if that makes sense
