Although "chioccole" may be "scrolls" in some contexts, here I believe they are "lead nuts" (presumably on a machine tool). The lead nut (chiocciola) is the part that, affixed to a sliding table or other moving machine part, imparts linear motion to the relative axis because it (the nut) is engaged with a rotating "lead screw" (madrevite). It seems, in my mind, perfectly logical to instruct the machine operator to disengage the nuts to prevent undesirable axis movements, although I admit that I have never before encountered a setup wherein the nuts can be disengaged at the press of a button.
