The sliding of the slider is utilized to realize the pulling and pulling function of the drawer. In order to make the drawer achieve a better use effect, an additional buffer is arranged inside the slide rail. When the slider slides, the buffering characteristics of the buffer are utilized to realize the buffering characteristics of the drawer when it is pulled and pulled, thereby avoiding the noise generated when the drawer is pulled and pulled or the slider being separated from the slide rail due to excessive force when pulling and pulling the drawer.
