a locking mechanism, comprising:
a first locking segment positioned on the engagement surface, wherein the first locking segment comprises:
at least two protrusions extending away from the engagement surface on a bottom of the top articulating portion, wherein the at least two protrusions are tapered between the bottom surface of the top articulating portion and a bottom surface of the two protrusions; and
recesses extending into the engagement surface of the top articulating portion and positioned between the at least two protrusions; and
a second locking segment extending away from the engagement surface and positioned adjacent to the first locking segment, wherein the second locking segment forms a continuous protrusion surrounding the at least two protrusions and recesses, and wherein the second locking segment is angled between the bottom surface of the top articulating portion and a bottom surface of the second locking segment; and
