Abstract:
1. A curtain bead chain fixing device, comprising: a bead chain guide way being extended across the fixing device for a bead chain serving as a pull cord for controlling a curtain to extend therethrough and become connected to the fixing device; a first elastically movable interfering element being provided with a first fixing hole and arranged to one of two opposite sides of the bead chain guide way to elastically movably extend into the bead chain guide way; and a second elastically movable interfering element being provided with a second fixing hole and arranged to the other side of the bead chain guide way to elastically movably extend into the bead chain guide way; wherein the first interfering element extended into the bead chain guide way interferes with the bead chain, such that the bead chain is prevented by the first interfering element from freely moving in and along the bead chain guide way; and wherein when the fixing device is adequately mounted to a wall surface with a fastening element extended through the first fixing hole, the first interfering element is forced out of bead chain guide way; and wherein the second interfering element extended into the bead chain guide way interferes with the bead chain, such that the bead chain is prevented by the second interfering element from freely moving in and along the bead chain guide way; and wherein when the fixing device is adequately mounted to a wall surface with a fastening element extended through the second fixing hole, the second interfering element is forced out of bead chain guide way.
