There's a blade thing coming out of the hinge on my laptop?

So, I have some version of a Lenovo Ideapad (not touchscreen.), and one day I accidentally dropped it off of my bed. Usually, it would've been alright, but that one time, the hinge had something coming out of it that seemed like a weapon type of blade. It absolutely will not budge after I tried to move it, and I imagine it's the part that goes inside the hinge itself.
I have no idea how to fix this, I don't know if I CAN fix it, or if I should take it to a shop. Help me out?
