[0057] The working principle of the present invention is as follows: when the user manually closes the curtain, the user pulls one end of the curtain to move, thereby driving the multiple sets of hooks 3 to move, and the multiple sets of pulleys 27 and the multiple sets of side wheels 28 move inside the slideway, and the auxiliary hooks 3 move, so that the user can manually control the curtain;

[0058] When the user uses the curtain through the opening and closing system, the user starts the driving motor 4 through the remote control or the mobile phone software control end, driving the driving shaft 5 to rotate clockwise, and the outer wall of the driving shaft 5 is threadedly connected with the inner wall of the two groups of movable seats 6. The two groups of movable seats 6 move toward the center end of the driving shaft 5, thereby driving the two groups of mounting plates 8 to move, and one end of the multiple groups of guide plates 13 is arc-shaped, and the multiple groups of guide plates 13 push the two groups of movable columns 10 respectively, so that the two groups of movable columns 10 are displaced in the direction of the two groups of push plates 9.

[0061] After the two groups of push plates 9 are separated from the two groups of support plates 29, the two groups of curtains are closed, the movable seat 6 continues to move, the multiple groups of movable columns 10 are respectively moved to the other end of the multiple groups of guide plates 13, and separated from the multiple groups of guide plates 13, and the multiple groups of springs 12 respectively push the two groups of push plates 9 to reset, so that the two groups of push plates 9 are respectively moved to the other side of the two groups of support plates 29, and the driving motor 4 is turned off.

[0063] First, the two groups of first tooth plates 7 are respectively moved to one side of the two groups of transmission gears 15, and the two groups of first tooth plates 7 are respectively meshed and connected with the two groups of transmission gears 15, so the two groups of transmission gears 15 rotate, thereby driving the two groups of transmission shafts 14 to rotate, and then driving the two groups of transmission bevel gears 16 to rotate, and the two groups of transmission bevel gears 16 are respectively meshed and connected with the two groups of linkage bevel gears 18, and the two groups of linkage bevel gears 18 rotate, thereby driving the two groups of linkage shafts 17 to rotate, and the multiple groups of linkage shafts 17 are respectively connected by synchronous belts, so the multiple groups of linkage shafts 17 rotate synchronously, driving the multiple groups of limit blocks 19 to flip, so that the multiple groups of limit blocks 19 are respectively separated from the multiple groups of limit grooves 30, and the fixed connection between the mounting seat 1 and the fixing seat 2 is released;

[0064] When the fixed connection between the mounting seat 1 and the fixed seat 2 is released, the two groups of movable seats 6 continue to move, driving the second tooth plate 21 to engage with the limit gear 23, and the limit gear 23 rotates, driving a group of limit shafts 22 to rotate. The multiple groups of limit shafts 22 are respectively connected by multiple groups of synchronous belts, so the multiple groups of limit shafts 22 rotate synchronously, thereby driving the multiple groups of winding wheels 24 to rotate, and then releasing the traction rope 25, so that the mounting seat 1 moves downward, so that the mounting seat 1 moves to a height suitable for the user to disassemble the curtains, thereby improving the practicality and convenience of the curtains.
