The second supporting member 2 may be made of a spring steel material for making a spring, such as manganese steel, and the second supporting member 2 may be made of a sheet strip, so that the second supporting member 2 can keep straight and has a certain plasticity in a normal state, so that when the second supporting member 2 curls towards or away from the first supporting member 1, the second supporting member 2 can store elastic potential energy, when the second supporting member 2 curls towards or away from the first supporting member 1, the second supporting member 2 can release the elastic potential energy, and the second supporting member 2 can be more labor-saving in a flattening process due to release of the elastic potential energy in the flattening process, and can keep a normal straight state after the elastic potential energy is completely released, so that the second supporting member 2 can more stably support the first supporting member 1.
The specific setting mode of the second supporting piece 2 not only can ensure the normal curling and flattening performances of the second supporting piece 2, but also can ensure that the flattening process is more labor-saving by means of the released self elastic potential energy, and the second supporting piece 2 can keep a normal straight state after the elastic potential energy is completely released, so that the second supporting piece 2 can support the first supporting piece 1 more stably.
In an alternative of this embodiment, at least one arc-shaped section 21 is provided in the section of the second support 2 along the extension direction of the second support 2; wherein, when the second supporting piece 2 is curled, the arc section 21 is elastically deformed to reduce the radian of the second supporting piece; when the second support 2 is flat, the arc-shaped section 21 is elastically deformed to increase the radian of the second support.

During the crimping process of the second support 2 away from the first support 1, the two ends of the arc-shaped section 21 are gradually and relatively far away, so that the bending radian of the arc-shaped section 21 is gradually reduced, and elastic potential energy is stored. When the two ends of the arc-shaped section 21 are relatively far apart to a maximum distance, i.e. when the arc-shaped section 21 is extended to a straight line, the second support member 2 reaches a maximum degree of curling, and the arc-shaped section 21 is bent to be closely attached to the first support member 1.
The opening of the arc-shaped section 21 is arranged towards the first supporting piece 1, and when the second supporting piece 2 is curled, the screen 6 can sequentially wrap the first supporting piece 1 and the second supporting piece 2 and is wound into a spiral shape, so that the wound screen 6 can still display information towards the projection of the external part.
In an alternative to this embodiment, at least one of the two ends of the arcuate segment 21 is connected to the first support 1.
The connection of the two ends of the arc-shaped section 21 with the first supporting member 1 refers to a connection in a broad sense, and includes a connection manner such as a fixed connection, a movable connection, a limiting clamping connection and the like.

During the process of crimping the second support 2 towards the first support 1, the two ends of the arc-shaped section 21 are gradually relatively far away, so that the bending radian of the arc-shaped section 21 is gradually reduced, and elastic potential energy is stored. When the two ends of the arc-shaped section 21 are relatively far apart to a maximum distance, i.e. when the arc-shaped section 21 is extended to a straight line, the second support member 2 reaches a maximum degree of curling, and the arc-shaped section 21 is bent to be closely attached to the first support member 1.
The opening of the arc-shaped section 21 is arranged away from the first supporting piece 1, when the screen 6 is wound, the second supporting piece 2 and the first supporting piece 1 are sequentially wrapped outside the screen 6, and the protection effect on the screen 6 during winding can be improved.
