The screen frame 1 is provided with a positioning groove 5. A plurality of positioning grooves 5 are distributed along the length direction of the screen frame 1. The positioning groove 5 is used to constrain the first connecting rod 2 and / or the second connecting rod 3. The first connecting rod 2 drives the second connecting rod 3 to move through the third connecting rod 4 hinged therewith. The driving mechanism can drive the first connecting rod 2 or the second connecting rod 3 to move through a driving motor, an electric push rod or the like. The movement of the first connecting rod 2 and the second connecting rod 3 relative to the screen frame 1 is realized.
