[0002] Curtains have the functions of sunshade, heat insulation, regulating indoor light, and interior decoration. Curtains include rolling curtains, folding curtains, etc. Pleated curtains are divided into venetian blinds, pleated curtains, honeycomb curtains, day and night curtains, etc. according to their different functions. Venetian blinds can adjust the light, and honeycomb curtains adopt a unique honeycomb design with constant temperature and sound insulation effects. Day and night curtains can be adjusted at will between light transmittance and opacity.
[0003] Most of the above-mentioned curtains include a curtain box, curtain cloth and a low rod. At least one set of middle rods is provided in the middle of large-sized curtains. The curtain cloth is pulled back and unfolded, folded and unfolded by a pull rope to adjust the shading effect. For example, a magnetic honeycomb curtain with application number 202022005378.4 uses a pull rope to drive the low rod and the middle rod to move up and down relative to the curtain box to achieve the folding and unfolding of the curtain cloth. However, this type of curtain needs to be in a horizontal state when used. The existing honeycomb curtains mainly adjust the length of the pull rope by manual knotting before leaving the factory. The operation is cumbersome and requires repeated knotting, which wastes manpower. Utility Model Content
