At this time, the user pulls the screen body 104, so that the screen body 104 drives the guide slider 201 to slide inside the guide slot 202. Under the joint action of the guide slider 201 and the guide slot 202, the screen body 104 is guided. At this time, the guide slider 201 drives the positioning card 2032 away from the inside of the positioning card slot 2033. When the guide slider 201 moves inside the guide slot 202, When the drain pipe is installed, the rotating ball 2031 rotates on the surface of the guide slider 201.
