Principle of embodiment:

initially, the sliding rod 2 is located at the lower side of the first supporting roller 1, the sliding block 22 is located at the lower side of the second supporting roller 5, the first connector can slide freely on the sliding rod 2, the sliding block 22 can slide freely on the second supporting roller 5, the second hook 14 is located at the side of the sliding rod 2 far away from the second supporting roller 5, the first hook 13 is matched with the sliding rod, the sleeve 11 is located at the side of the window shade close to the first connector, the accommodating groove 6 is located at the lower side of the first supporting roller 1, and the accommodating groove 6 is located at the side of the first connector close to the second supporting roller 5, as shown in fig. 1; the driving plate 16 is positioned between the shifting plates 15; the lower edge of the driving piece 16 is higher than the upper edge of the first connecting head and lower than the upper edge of the shifting piece 15;

when the curtain needs to be drawn, the driving pieces 16 are separated and positioned at two ends of the first supporting roller 1, the driving pieces 16 drive the shifting pieces 15 to straighten the upper edge of the yarn curtain, at the moment, the first connecting heads are uniformly distributed along the first supporting roller 1, then the gear 26 rotates, the second ends are positioned at two ends of the second supporting roller 5 to straighten the upper edges of the window shade and the stay wire, and at the moment, the first connecting heads correspond to the sliding blocks 22;

for convenience of description, the first support roller 1 rotates clockwise by about 270 degrees, the second support roller 5 rotates clockwise by about 90 degrees, the first hook 13 and the second hook 14 face upward, the radius of curvature of the first hook 13 is matched with the outer diameter of the sliding rod 2, so that the first joint rotates around the axis of the sliding rod when the first support roller 1 rotates, see fig. 8;

then the adjusting cylinder is operated, the second supporting roller 5 moves towards the first supporting roller 1, the driving roller 7 also moves towards the first supporting roller 1 under the action of the connecting mechanism, the driving roller 7 presses the yarn curtain on the first supporting roller 1, the sleeve 11 is positioned at the upper side of the first hook 13, the first spring 19 is extended, and the sliding plate 18 and the side plate 17 slide relatively, see fig. 9;

then the lifting rope 20 is loosened by the clamping mechanism (the principle of the clamping mechanism is that the pushing cylinder extends when needing to be clamped by the stretching of the pushing cylinder, the pushing rod extrudes the inclined plane, shortens when needing to be loosened and is far away from the clamping block), the iron beads 21 come out of the embedded groove 23, the sleeve 11 moves downwards under the action of gravity and is hooked by the first hook 13, and the upper edge of the window shade is connected by the first connecting head, which is shown in figure 10;

then the cylinder motor is operated, the sliding rod 2 is rotated upwards and is disengaged from the second hook 14, then the first electric cylinder 3 is shortened, and the sliding rod 2 enters the receiving groove 6, see fig. 11;

the first supporting roller 1 and the driving roller 7 rotate, the first connecting head and the window blind move downwards, the lower hem of the window blind descends and is dragged on the ground, the weight of the lower hem of the window blind is greatly increased, and the upper edge of the window is away from the ceiling by a certain distance, so that the shading effect is not influenced when the upper edge of the window blind descends by a certain height; see fig. 12;

when reduction is needed, the first supporting roller 1 and the driving roller 7 rotate, the first connecting head and the window shade move upwards, the iron beads 21 are upwards close to the embedded groove 23, the iron beads 21 are sucked into the embedded groove 23 by the electromagnet 24, and then the lifting rope 20 is clamped by the clamping mechanism, which is shown in fig. 13;

under the action of the first electric cylinder 3, the second supporting roller 5 is far away from the first supporting roller 1, the first spring 19 is shortened, (at the moment, the driving roller 7 is still pressed against the screen curtain), under the action of the lifting rope 20, the screen curtain is far away from the first supporting roller 1, the sleeve 11 is hooked with the first hook 13, so that the first hook 13 is pulled towards the second supporting roller 5 by the sleeve 11, the second hook 14 is towards the first supporting roller 1, and the pulling action of the screen curtain is used for positioning the second hook 14; see fig. 14;

then the first electric cylinder 3 is extended and rotated at the same time, the slide bar 2 enters the second hook 14, and is engaged with the second hook 14, see fig. 15;

then first supporting roller 1 rotates certain angle clockwise, and first connector also rotates along with first supporting roller 1, and cover 11 and first crotch 13 are thrown off, then driving roller and second supporting roller 5 keep away from first supporting roller 1, realize the separation of window shade 8 and yarn curtain this moment promptly, then first supporting roller 1 and second supporting roller 5 anticlockwise rotation can get back to initial condition.
