<p>The stopper has a blocking groove extending parallel to a adjustment direction (Z) and offset with respect to an adjustment groove (29) angularly around the adjustment direction. The blocking groove immobilizes a reserve pin (6) to block the rotation of a circular base cylinder-shaped rod (4.2) of a support component (4) in a receptacle (21) of a support casing (2). The rod includes teeth (4.21, 4.22) co-operating with throats of the receptacle, where the stopper is in a blocking configuration. The throats are juxtaposed parallel to the adjustment direction. An independent claim is also included for a method for adjusting height of a stopper.</p> |
