[0045] In the smart terminal, the fixed shell pulls the screen through the pull rope, driving the movable shell to do telescopic movement together, and the screen moves twice as far as the movable shell. However, during use, the movement distance of the screen in the smart terminal relative to the fixed shell is twice the stretching distance of the whole machine. The pull rope occupies a large structural space. At the same time, the tension of the pull rope in the expanded and contracted states is different, so the tension on the screen is also different, resulting in different amounts of screen arching.
