During the unfolding process of the first sliding plate, although the first sliding plate is mostly pulled out of the device, the touch flexible display screen 10 is always protected due to the following movement of the P-shaped first accommodating cavity. The rotating shaft 53 is added to assist the sliding to change into partial rolling, so that the sliding is smoother, and the curvature radius of the sliding bending part is increased, so that the service life of the touch flexible display screen 10 is further prolonged. In other embodiments, the second form is a horizontal P-shaped form in which the rotating shaft is located at the lower portion of the strip-shaped cavity, that is, the strip-shaped cavity is attached to the back of the first sliding plate, and the principle is similar to the first form, and reference is made to the first form, which is not described again.
