Aquí, un ejemplo:

Gracias por actualizar tu código. Baso esta revisión en su nuevo código, que debe trasladar a la pregunta. El problema es que el \ifxancla anterior ya no se ejecuta. Entonces necesitas mover \ifxel ancla.
\anchor{tm}{\ifx\pgf@posicion@manivela\pgf@izquierda
\northeast \pgf@x=-\pgf@x \pgf@y=1.5\pgf@y
\else
\northeast \pgf@x=\pgf@x \pgf@y=1.5\pgf@y
