所述左侧转动支撑件5和右侧转动支撑件6分别由多根指形结构连成一体构成，它们的转动导向结构包括排列成栅板状的导向板71并设置导向槽72，所述导向板71和指形结构的间隙配合。所述左侧转动支撑件5和右侧转动支撑件6分别设有与导向槽72配合的导向杆51、61，所述导向槽72的顶部设置有平槽720，并利用铰链转至对应柔性屏展平的状态时，由柔性屏长度的约束而所述左侧支撑结构和右侧支撑结构向中间回退的运动，使所述导向杆51、61进入所述平槽720而将铰链转至对应柔性屏展平的状态锁定。
所述栅板状导向板71可以由连接结构73连接成整体，然后安装在左侧支撑结构、右侧支撑结构中。所述左侧转动支撑件5和右侧转动支撑件6也可以是其它的转动部件，比如板、块等。
所述中间支撑结构和左侧连接臂之间以及和右侧连接臂之间设置有扭力机构，以提高操 作手感和提供随时停止随时定位功能。所述扭力机构包括一对簧管件8，所述簧管件8处在中间支撑结构100中，所述簧管件8具有分别对应左侧连接臂和右侧连接臂的簧管81、82，一个簧管件8与同一侧的左侧连接臂3和右侧连接臂4对应，并分别通过轴80连接，所述轴80穿过中间支撑结构、簧管和连接臂，其中，与连接臂固定连接，与中间支撑结构间隙配合，与簧管为被夹紧的关系。所述扭力机构也可设置在发生相对转动的其它部位间，
应用上述铰链的移动终端，以手机或电子书为例，所述柔性屏300铺设在所述铰链的内侧，并且和所述中间支撑结构之间，只和所述中间支撑结构100的中间部位101固定连接，所述柔性屏和左侧支撑结构、右侧支撑结构固定连接。所述中间支撑结构100、左侧转动支撑件3和右侧转动支撑件4、左侧支撑结构、右侧支撑结构共同构成柔性屏展平时的支撑结构。
以上所述仅为本发明的具体实施例，但本发明的结构特征并不局限于此，任何本领域的技术人员在本发明的领域内，所作的变化或修饰皆涵盖在本发明的保护范围之中。
