I used my drill today and I went to drill a into a piece of brick and the bit went back into the drill somehow. I can open and close the chuck but the drill bit will not come out. When I push on the end of the chuck it goes into the drill, it has a lot of movement.

I tried everything to try and get the drill bit out, nothing works, I don't understand how it could get stuck in the drill when I can still open and close the teeth to the chuck. Thanks.
