Can anyone tell me what this nut is called and how to remove it in a way I can return the mechanism to normal working order? Also, what kind of special tools will I need?
The first photo is of the outside end-cap of a set of vertical blinds. The gear on the other side, not shown in the first picture, connects into a long shaft used to rotate the row of blinds to vary the amount of light coming through a glass door.
I'm actually trying to replace a broken axle that held some pulleys for the draw strings purposed to slide all the blinds in one direction or another. However, the pulley axle was located in this end-cap assembly. In order to get to their area, I need to remove this end, it looks like, and the only thing barring removal seems to be this weird looking nut.
Second photo is a view from the other side which shows how the gear couples to the shaft. Maybe there is a different way to uncouple and remove the end cap?

I wish comments would allow pictures, but what you have is something generically called a "push on fastener" I have to disagree with jsotola, I consider them "barely reusable", they often break when when removing, esp. if old. I wouldn't count on being able to re-use it.
I attached a pic of something what I think is close to what you have.
