The other end is wound around the first hole 212 opened by the housing 21 through the wire wheel 114, and the bottom plate 22 is extended downwardly. The third wire body 1133 is connected to the winding wire at one end. The other end of the rod 112 is disposed around the outer edge of the winding bar 112. The other end of the third rope body 1133 extends downwardly from the second hole 213 of the casing 21 via the wire wheel 114. The bottom plate 22, when the user operates the bottom plate 22 to pull down, simultaneously pulls and The second and third rope bodies 1132 and 1133 are connected, and the first rope body 1131 is originally received in the first reel 1111a and is also drawn around the outer edge of the winding rod 112, and is originally wound around the first winding body 1111a. The elastic winding piece 1111c outside the spring reel 1112 is temporarily pulled and wound around the outer edge of the first accommodating disk 111b of the first reel 1111, and the elastic winding piece 1111c is elastic when the bottom plate 22 is retracted by operation. Release the rewinding to retract the outer edge of the first spring reel 1112, and simultaneously drive the first reel 1111 to rewind and retract the first rope body 1131 to the first reel 1111a, and the other end of the first rope body 1131 pulls the The winding bar 112 rotates to recover and wind the second and third rope bodies 1132, 1133 to the outer edge of the winding bar 112, and closes the bottom plate 22 to the casing 21, and simultaneously folds the curtain 23 to complete all actions. . The main purpose of the present invention is to directly mount the components such as the winding bar 112 and the winding spring wheel set 111 on the base 11, and directly form the structure on the base 11 to fix the components, thereby simplifying the component and reducing the manufacturing cost. And reduce the overall height to reduce the space required for the overall setup.
