1. A device for fixing a position of at least one variable guide vane row of a turbomachine, guide vanes of each variable guide vane row being coupled together by a synchronizing ring having at least one opening therein, the device comprising:
a support arm fixed relative to the turbomachine;
a plurality of ring fixing sets coupled to the support arm for fixing the position of the at least one variable guide vane row, each ring fixing set including:
a holding member coupled to the support arm and including an elongated plate having an elongated hole extending along a longitudinal extent of the elongated plate; and
a fixing bolt extending through the elongated hole and including:
a first end configured to couple to the holding member such that the fixing bolt is adjustable relative to the holding member along both a longitudinal extent of the holding member and a longitudinal extent of the fixing bolt, and
a second end configured to couple to the at least one opening of the synchronizing ring in order to fix a circumferential position of the synchronizing ring and the position of the guide vanes of the variable guide vane row to which the synchronizing is coupled.
