[0029] Next, the technical solutions in the embodiments will be described clearly and completely in conjunction with the attached Figures 1-9 , as shown in Figure 1 and Figure 5 , each adjustment unit can be inserted and connected through the cooperation of the engaging block 2 fixed on the top surface and the engaging groove 3 opened on the bottom surface. Since the top of the engaging block 2 is provided with a convex arc structure, the engaging block 2 can be stably installed in the engaging groove 3, so that several groups of adjustment units can be sequentially installed below the mounting plate 10. By installing the adjustment units, the distance from the bottom of the daylighting curtain to the window sill or the ground can be controlled, which is beneficial to reducing the divergence of sunlight into the room.

[0030] As Figures 2-4As shown, when the right extension plate 5 moves to the right, the right extension plate 5 will drive the left extension plate 5 to move to the left through the connecting gear 4, so that the two extension plates 5 move away from each other synchronously. By cooperating the two extension plates 5 with the adjustment frame 1, daylighting curtains of different widths can be adapted for use. This is beneficial to improving the applicability of the device while reducing the possibility of light leakage and avoiding affecting the uniformity of indoor daylighting;

[0031] When the two extension plates 5 move horizontally, the extension plate 5 will drive the slider 6 fixed on the outer side to move horizontally in the chute on the inner side wall of the adjustment frame 1. The setting of the slider 6 makes the movement of the extension plate 5 more stable and avoids the situation of the extension plate 5 falling off;

[0032] As Figure 6 shown, through the threaded connection between the connecting threaded block 7 and the connecting screw 8, the connecting screw 8 can be threadedly connected to the right side of the right extension plate 5. Since the threaded convex block is fixed on the top surface of the connecting screw 8 and the threaded groove is provided on the bottom surface of the connecting screw 8, adjacent two connecting screws 8 can be threadedly connected. Through the threaded connection of adjacent two connecting screws 8, several groups of connecting screws can be correspondingly installed on the right side of the right extension plate 5. By pulling one group of connecting screws 8, multiple groups of right extension plates 5 can be driven to move to the right, making the operation of the extension plate 5 more convenient and beneficial to improving the use experience of the daylighting curtain;

[0033] As Figure 4 and Figures 7-9 shown, after the adjustment unit is installed, the engaging block 2 will be slidably inserted into the engaging groove 3. The turntable 9 can drive the threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the connecting frame 12, the rotation of the threaded rod 11 will drive the connecting frame 12 to move vertically downward. Since the connecting frame 12 penetrates through the adjustment frame 1, the connecting frame 12 will drive the limiting plate 13 fixed on the bottom surface to be inserted into the limiting groove opened in the upper right of the corresponding adjustment frame 1, so as to limit the left and right positions of adjacent two adjustment frames 1, and further avoid the situation of the engaging block 2 moving out of the engaging groove 3, which is beneficial to improving the installation stability of the adjustment frame 1.
