What is the Name and Construction Process for Interlocking Gear Mechanisms?

[NextDaVinci]

I am referring to the gear-like circular faces that interlock when forced together and allow rotation when unlocked on these arms. I want to design one, but I can't seem to find out what its called.

Any advice as to how to make these out of metal in a basic machine shop is also welcome.

Thanks!

Welcome to PF;
Have a look in the manual that comes with it to find out what the manufacturer calls them.
I know them as "locking screws" or "locking pins" depending on their operation.

The simplest operation is just to have a bolt through the joint - tightening the bolt makes the joint stiffer.
After that you can have all the fun you like with toothed wheels and pins - which will only lock the joint at particular angles.
