1. A scissor mechanism, comprising:
(a) a branched rivet containing three or more radially projecting coplanar protrusions spaced apart around a perimeter of said branched rivet, each of said three or more radially projecting coplanar protrusions having a single arm rotatably mounted thereon,
each of said arms being of equal length,
each of said arms being rotatable about said protrusion in a single plane,
each of said arms is rotatably mounted on one of said protrusions at a midpoint of said arm, and,
each of said arms has
an orthogonally extending rod attached proximate to an upper end of said arm and
an orthogonally extending sleeve attached proximate to a lower end of said arm, said rod and said sleeve extending in a direction parallel to each other.
