Embodiment Construction
[0027] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The content mentioned in the embodiments does not limit the present invention, and the present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] A flexible and variable force cord retracting device provided by the present invention includes a hollow metal rod 1 for winding the cord and fixed mounting parts 2 installed on the left and right ends of the hollow metal rod 1. When in use, the fixed mounting part 2 It can be fixed directly above the window head with screws; one end of the hollow metal rod 1 is embedded with a flexible variable force elastic structure, and the other end of the hollow metal rod 1 is embedded with a driven structure. The ends are rotatably connected to the fixed mounting part 2 through a flexible variable force el...
