How can I unlock the passcode without restore it? Because I never backup my data. I don't want to lose all of my data

That is not possible. If you didn't want to lose your data, you should be regularly creating backups of data. There is no way for you to create a backup now, and getting the iPhone to work again is going to require you to restore it to factory. Without a backup, you will have to set it up as new. The time to begin creating backups is before you have a problem.
