The roller blind 2 of the present invention is composed of the above components, please refer to Fig. 4 to Fig. 7-1, and cooperate with As shown in Fig. 7-2 and Fig. 11, when the components of the roller blind 2 are assembled with the fixing device 5, due to the snap button 52 Using the elastic range of the spring 53 with the inside of the spring damping sleeve 54, when the roller blind 2 is about to be installed on the window Above, first fix the fixing brackets 7 at the left and right ends, and then assemble the roller blind 2 in the following two ways. Middle: The first method is as shown in Fig. 7-1 to Fig. 8-3, and as shown in Figs. 10 and 11, first install it in the set The first fixing post 521 at the left end of the tube 3 is guided into the through hole 724 by the guiding groove 725 fixed at the left end. When the safety latch 57 is pulled out from the first through hole 527, the telescopic end 572 passes through the first through hole 527. The width of the triangular shape is reduced in the hole 527, so that the safety latch 57 can be pulled out completely, and the original locking The pressing buckle 52 is unlocked in the state of When the guide groove 725 fixed on the right end is about to be introduced into the through hole 724 for positioning, the guide groove 725 can be pressed at the same time. A fixing post 521 compresses the spring 53 installed in the first chamber 524 and the second chamber 545, And let the pressing button 52 move in the second chamber 545 and toward the abutting convex portion 543, and the pressing button 52 An idling can be formed in the second chamber 545, so that the third fixing post 41 is positioned toward the through hole 724, and the After that, when the first fixing post 521 that was originally pressed is released, the elastic force of the compressed spring 53 will gradually gradually return to its original state, and push the button 52 away from the abutting protrusion 543 and gradually reset, so that the The second embedding rods 525 are respectively abutted and fixed on the abutting ends 516 to prevent the pressing buckle 52 from passing through the first opening. The outer side of 512 is pulled out, and finally, the safety latch 57 is inserted through the first through hole 527 to make the press buckle 52 A locked state is formed, so that the curtain sheet 8 is opened and closed. The second method is like Figure 7-1 and Figure 7-2, And as shown in Figures 8-3 to 11, the third fixing post 41 first installed on the right end of the sleeve 3 is fixed on the The guide groove 725 on the right end is guided into the through hole 724 for positioning, and then the safety pin 57 is passed through the first through hole When the 527 is pulled out, the telescopic end 572 passes through the first through hole 527 to reduce the width of the triangular shape, so as to reduce the width of the triangle. It is convenient to pull out the safety latch 57 completely, unlock the pressing buckle 52 in the original locked state, and then, When the first fixing post 521 installed at the left end of the sleeve 3 is about to be guided into the guide groove 725 fixed at the left end During the process of positioning the through hole 724, the first fixing post 521 can be pressed and installed in the first chamber at the same time. 524 and the spring 53 inside the second accommodating chamber 545 are tightened, so that the pressing buckle 52 is in the second accommodating chamber 545 and Moves toward the abutting protrusion 543, and the pressing button 52 can form an idle rotation in the second chamber 545, so that the The first fixing post 521 is positioned toward the through hole 724 , and after that, the first fixing post 521 is initially pressed when released After that, the elastic force of the compressed spring 53 will gradually return to the original state, and the pressing button 52 will gradually move away from the The abutting protrusions 543 are pushed and gradually reset, so that the second embedding rods 525 are respectively abutted and fixed on the abutting ends 516, to prevent the push button 52 from coming out from the outside of the first opening 512, and finally, the safety latch 57 By inserting into the first through hole 527, the pressing button 52 is in a locked state, so that the roller blind 2 can be inserted from the left or right end of the roller blind 2.
