将张紧机构设置为弹性张紧机构，通过第一弹性件426连接第一转接座424和第三滑块422，并使第一屏体转接件200与第一转接座424连接，既能够实现柔性屏20的张紧，能够避免柔性屏20与第三滑块422的硬性连接。
为使柔性屏20始终保持张紧平整状态，在支撑结构件10伸缩的过程中，第一弹性件426对第一转接座424所施加的张紧力方向保持不变。第二滑移支撑件130朝着远离第一滑移支撑件120的方向移动以使支撑结构件10伸展时，张紧力方向与第二滑移支撑件130的移动方向相反；第二滑移支撑件130朝着靠近第一滑移支撑件120的方向移动以使支撑结构件10收缩时，张紧力方向与第二滑移支撑件130的移动方向相同。
