5. Specific implementation methods:

As shown in Fig. 2, Fig. 3, Fig. 4, and Fig. 5, the utility model includes several blades 1, stay cords 2 and angle adjustment lines 3, and several blades 1 are connected together by stay cords 2, and both sides of the stay cords 2 are connected together. The angle adjustment line 3 for adjusting the turning angle of the blade 1 is installed. In addition, it also includes a rotating rod 4, a guide rail seat 5 and a driving part. Be to match, the side of turning bar 4 ends is provided with the driving part that traction turning bar 4 rotates, and the top end of stay cord 2, angle adjustment line 3 is installed and connected on the turning bar 4. Rotation bar 4 can be semicircle type, also can be semicircular ring type. The cooperation between the rotating rod 4 and the guide rail seat 5 is tightly squeezed together, and the ends that are arranged on the two sides of the rotating rod 4 are respectively provided with a driving part, and the two driving parts can be at the same end of the rotating rod 4 or can be distributed on Both ends, the driving part can be pull bar 12, also can be rope 13. Mounting holes 14 are arranged on the top surface of the guide rail seat 5 , and adjustment screws 15 are also installed outside the guide rail seat 5 .

As shown in Fig. 6, Fig. 7 and Fig. 8, the utility model also includes a rolling shutter mechanism, which includes a lock outer cover 6, a lock inner cover 7 and a spring 8, and the lock outer cover 6 is closed at one end and opened at the other end. 9. The spring 8 and the lock inner sleeve 7 are sequentially stuffed into the lock coat 6 from the opening 9. The lock coat 6 and the lock inner sleeve 7 are respectively provided with holes 10 and through holes 11, and the tail of the drawstring 2 is worn. Vias 10 and vias 11. When the curtain is to be put away, overcome the resistance of the spring 8 and press down the inner sleeve 7 of the lock, so that the hole 10 on the outer sleeve 6 of the lock is aligned with the through hole 11 on the inner sleeve 7 of the lock, so that the stay cord 2 can be separated from the shutter mechanism. Push the lock cover 6 upwards together, and tighten the stay cord 2. The blades 1 are stacked together. Finally, release the lock inner cover 7. Under the action of the spring 8, the upper hole 10 of the lock cover 6 and the The through hole 11 on the lock inner sleeve 7 is staggered to clamp the stay cord 2, and the blade 1 is put away.

The principle of the utility model is: after installation, pull the pull bar 12 or the rope 13 to make the rotating rod 4 rotate around the guide rail seat 5, so that the blade 1 tilts in one direction as the rotating rod 4 turns over, because the rotating rod 4 and the guide rail seat The fit between 5 is tightly squeezed together, and a certain frictional force is generated between them, and when turning to a certain angle, the rotating rod 4 can stop steadily and will not rotate in the opposite direction. To make the blade return to the horizontal position, another pull bar 12 or rope 13 must be pulled again to make the blade 1 rotate in the opposite direction along with the turn bar 4 and reach the horizontal position. When the rotating rod 4 is semicircular, the rotating rod 4 is more elastic, the cooperation between the rotating rod 4 and the guide rail seat 5 is better, and the friction effect is better.
