  • the second screw member 7 When it is necessary to adjust the tightness of the belt 13, the second screw member 7 is loosened, so that the frame 2 can be controlled to move linearly with respect to the curtain rod 1 to adjust the tightness of the belt 13. When the belt 13 is adjusted to a desired tightness, the second screw member 7 is secured again.
  • the rail 11A and the other rail 11B there can be two rails of the curtain rod 1, and they are the rail 11A and the other rail 11B arranged opposite to each other.
  • the other rail 11B also has two side panels 111 arranged parallel to each other and separated from each other and a spacing 112 defined between the two side panels 111.
