Flexible guide with adjustable translation table for rotary resonator mechanism, in particular of a horological movement

A flexible guide for a rotary resonator mechanism, the guide comprising:

• a fixed support;
• an element movable relative to the fixed support;
• at least one main flexible strip allowing the movable element to move relative to the fixed support by bending the main flexible strip(s) in a rotary movement about a centre of rotation, the flexible guide being arranged substantially in a plane;
• at least a first translation table joined to one end of the main flexible strip, so that the first translation table is configured to move in translation at least in part under the effect of the bending of the main flexible strip;
• and
• means for adjusting the rigidity of the first translation table,
• wherein the first translation table includes at least one secondary flexible strip, the at least one secondary flexible strip is perpendicular to the main flexible strip in the rest position of the flexible guide.
