[0002] With the progress and development of science and technology, the roller shutter has been widely used in residential, apartment, office building and public places. The roller shutter in the prior art is usually a pull rope type roller shutter. The user lowers or raises the curtain body by pulling the pull rope and keeps the curtain body at the desired position by the locking mechanism. However, the pull rope is made of plastic material, and if the curtain body of the pull rope type roller shutter is large, the pull rope is prone to breakage, and the service life is short. At the same time, the locking mechanism in the prior art has poor stability for locking the curtain body, and is inconvenient to use. Therefore, the roller shutter in the prior art cannot meet the use requirements of modern people.
