Don't do that if you are not good for repairing laptop. That will damage your laptop and be dangerous.
Either repair your laptop adapter or buy a new adapter. If you can't let your laptop charger repaired by yourself, you had better replace a new charger.If you are on a budget on a new charger, consider buying a third party charger:
