A kind of Roman Shade (also a roman shade, a hundred curtain or a horizontal curtain) developed by the curtain industry. The Romance curtain mainly uses a so-called curtain ejector group to control the traction cable to drive the curtain body designed by the roll or other materials to form a hundred fold, wave, flat fold and the like. It is known that the traction cable is usually connected to the lower portion of the curtain body at the bottom end. When the curtain body is to be wound up, the traction cable is rolled to interlock the lower portion of the curtain body to start winding; however, the main control curtain body is controlled. The controller for lifting up and down includes a set of bead chained bead chain, which can drive a rotating shaft of the winding traction cable, and when the two-way controlled bead chain rope is pulled, the bead chain seat drives the rotating shaft Roll up, or loosen the traction cable to achieve the function of lifting up and down. Such structures are, for example, M290529, "The Curtain's Bead Chain Control Block Structure", announced by the Republic of China on May 11, 2006, and M261586, "The Pearl of the Curtains," announced by the Republic of China on April 11, 2005. Chain Control Device", No. M420276 announced by the Republic of China on January 11, 2012 Structure and so on.
