Abstract: A bi-axial swivel assembly allows the rotation of a bracket around the longitudinal axis of a support shaft when the restriction cam lies inside an imaginary reference plane. The attitude of the bracket is allowed to change around the longitudinal axis of the support shaft. Only if the bracket allows the restriction cam get off a recess, the perpendicular surface serves to prevent the restriction cam from protruding outside the imaginary reference plane. The attitude of the bracket can be prevented from changing around the rotation axis perpendicular to the longitudinal axis. The bi-axial swivel assembly allows the wire to penetrate through first and second hollow spaces. When the bracket rotates around the longitudinal axis, the wire is only forced to suffer from a slight torsion within the first hollow space. The wire can be protected from a larger flexure.
