i cant leave my clan can anyone helt me

Go to this page scroll all the way down and search for your name. Next to it should be a Quit button.

If you just dont know how to, you simply press the "clan" button up in the left corner and scroll down. Next to your name there will be a "quit" button.
Edit : too slow

Do note that if your clan is in clan war, you cannot leave.
