Description says spring loaded 510 pin so turning it won't help.
If you press down on it does it move? Or is it stuck? Sometimes they need a little persuasion to move for the first time.
If it does move, then the 510 on your doge is just longer than normal (growing trend as pablo said) and there's not much you can change to get it to fit.
I guess you could take some material off the 510 insulator to let the positive pin recess higher up into the base. But then you can't use it on a hybrid connection or it will short.
If you don't have a mechanical mod with hybrid connection, tear into the doge and see if you can sand down the insulator to allow the positive pin to be run further into the base. Take the smallest amount off at a time and test it. Once you take too much off your screwed.
