The utility model relates to a disconnect -type frequency modulation structure including a casing, one first drive change, a second drive change with a connecting piece. Wherein this first commentaries on classics piece that drives the commentaries on classics piece in order can mutual driven mode setting up in an accommodation space of this casing with this second, this connecting piece joins this first driving changes the piece, and this connecting piece has a draw -in groove, in a separation blade one end projection to this draw -in groove of this casing to make this connecting piece can't be relatively this first driving change a separation, again the one end of this connecting piece can be controlled and drive this first drive to change rotate. From this, this disconnect -type frequency modulation structure because of first drive to change to drive with the second change the piece and hide completely and locate this casing, and can avoid frequency modulation structure or (window) curtain blade to damage.
