As an embodiment of the present invention, the fixing clip 84 includes a clamping plate 841, a rotating post 842, and a strong spring 843; the number of the clamping plates 841 is two, and the rotating column 842 is arranged between the two clamping plates 841; the number of the strong springs 843 is two and the strong springs are respectively arranged at two sides of the rotating column 842; when the curtain is in work, the clamping force of the fixing clamp 84 is effectively enhanced due to the arrangement of the double-strong spring 843, the phenomenon that the curtain falls off in the use process is effectively avoided, meanwhile, the fixing clamp 84 is used for clamping the curtain cloth, so that the curtain cloth is more convenient to mount and dismount, and the curtain cloth is convenient to replace and wash when being used in a family.

The specific working process is as follows:

when the device works, firstly, the auxiliary end 3 is pulled away from the power end 1, so that the extension section 6 and the extension rod 71 fixedly connected with the auxiliary end 3 are displaced relative to the guide rail section 2, the first lead screw 27, the second lead screw 28 and the third lead screw 29, so that the distance between the power end 1 and the auxiliary end 3 is changed, when the distance between the two is properly adjusted, the inflation valve arranged on the side surface of the auxiliary end 3 inflates the inflation bag 75, so that the inflation bag 75 deforms, the extension section 6 and the guide rail section 2 are maximally displaced, sufficient pressure is generated on the power end 1 and the auxiliary end 3 along with the increase of the deformation degree of the inflation bag 75, so that the adsorption head 11 and a window sill are tightly combined, so that the installation is completed, then, three kinds of curtain fabrics with different light transmittances and wind permeabilities are sequentially fixed with the hooks 8 in the first chute 21, the second chute 22 and the third chute 23, then the motor 46 is started through the controller, the output shaft of the motor 46 rotates to drive the driving wheel 47 to rotate, because the driving wheel 47 is meshed with the first gear 41 in the initial state, the rotating driving wheel 47 drives the first gear 41 to rotate so as to enable the first lead screw 27 fixedly connected with the first gear 41 to rotate at a constant speed, the first lead screw 27 rotates in the first slide rail 24, so that the first slide block 271 meshed with the first lead screw 27 in the first slide rail 24 moves at a constant speed, the first slide block 271 moving at a constant speed drives the curtain so as to enable the first layer of curtain to be pulled open at a constant speed, when the first slide block 271 moves to the auxiliary end 3 under the meshing rotation of the first lead screw 27, the first slide block moving continuously generates pressure on the extrusion plate 51, so that the extrusion plate 51 moves towards the inside of the fourth chute 5, so that the extrusion bag 52 in the fourth chute 5 deforms, and the deformed extrusion bag 52 slowly introduces the internal gas into the inflatable bag 53 through the duct, the air bag 53 is deformed, so that the sliding plate 45 moves in the first guide groove 44, the motor 46 on the upper surface of the moving sliding plate 45 also moves and is finally engaged with the second gear 42, so that the second gear 42 rotates, the rotating second gear 42 drives the second lead screw 28 to continuously rotate, at this time, due to the displacement of the motor 46, the first gear 41 changes from rotating to stationary, the first sliding block 271 stops moving, the second sliding block 281 does constant-speed motion under the engagement transmission of the second lead screw 28 and slowly pulls the second layer of window curtain, when the second sliding block 281 reaches the auxiliary end 3, the pressing plate 51 is also pressed, so that the pressing bag 52 introduces more air into the air bag 53, the sliding plate 45 continuously moves with the motor 46, the operation is repeated until the third sliding block 291 completely pulls the third layer of window curtain, the third sliding block 291 presses the pressing plate 51, after the squeezing plate 51 pushes the air in the squeezing bag 52 into the air bag 53, the driving shaft and the motor 46 are separated from the third gear 43 under the driving of the sliding plate 45, at this time, the opening of the curtain is completed, when the curtain needs to be closed, the motor 46 is controlled by the controller to rotate reversely, so that the third lead screw 29, the second lead screw 28 and the first lead screw 27 rotate reversely, the third slide block 291, the second slide block 281 and the first slide block 271 move reversely until the third slide block is reset, and the three layers of curtains are closed.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
