The spool is located within the adjustment aperture and the spool is movable within the adjustment aperture in a radial direction of the spool;

When the reel completes the winding of the curtain cord, the reel is fixed in the adjustment hole by the tension of the curtain cord.

The curtain rope fixing seat is located at two ends of the curtain, and the curtain rope fixing seat is fixed on the window frame, and the two ends of the curtain rope are respectively fixed by the curtain rope fixing seat, and the curtain slides up and down on the fixed length curtain rope, once the curtain is installed, the curtain The rope does not need to be adjusted in length. The length of the curtain cord can be adjusted according to the length of the window before installation, and the curtain cord is inserted through the rope hole of the reel and then fixed. When adjustment is needed, the reel is rotated. Since the reel can jump up and down in the adjustment hole, a certain space is left for the winding curtain rope, and the length of the curtain cord is adjusted, since the ends of the curtain cord are fixed, the curtain The tension of the rope causes the reel to remain in the adjustment hole after adjusting the length of the curtain cord. When it is necessary to adjust again, the curtain rope is relaxed, and then the adjustment is repeated, and the above steps are repeated. Depending on the length of the window, the length of the curtain cord can be adjusted to meet the need to mount the curtain to different windows.

Preferably, the method further comprises a curved tooth surface, the curved tooth surface is located on the end surface of the body, and the curved tooth surface is located at one end of the adjusting hole; and a disk is integrally formed with the spool at one end of the roller, The circumferential surface is provided with serrations; the serrations on the disc cooperate with the curved serration surfaces to prevent the reel from rotating within the adjustment aperture after the curtain cord is tensioned. A "shaped" groove is formed in the center of the disc. When the reel falls due to the tension of the curtain cord into the bottom of the adjustment hole, the serration cooperates with the latch to ensure that the reel does not rotate within the adjustment hole. When adjustment is needed, insert the paddle into the “one” groove, and pull the reel. The serration on the reel pulls out the tooth. Because the diameter of the upper part of the adjustment hole is larger, the reel moves upward and adjusts as needed.
