柔性显示屏6使用完成后需要收纳时，按压开关按键4052触碰开关54使电路板43控制驱动件45驱动驱动轴451转动，由于驱动轴451远离驱动件45的一端固定于螺杆493内，即驱动轴451固定于插接于螺杆493的通孔4932内的连接杆484，连接杆484通过固定支架48固定于壳体40，且驱动件45固定于转动框42内，因此，驱动件45驱动所述驱动轴451转动使驱动件45相对于螺杆493转动，即驱动轴451的转动能带动转动框42在壳体40内转动，使柔性显示屏6收卷于转动框42上，至柔性显示屏6全部收纳于壳体40内， 拉柱7挡止于壳体40的通槽4020的外表面。此时，转动框42回转了最大旋转圈数，柔性显示屏6无法再被向内收纳，转动框42也无法向内转动，方便携带便携式显示装置100。
便携式显示装置100需要充电时，将充电插头穿过插入孔4062插接于USB接口86，USB接口86通过充电电路板8及电路板43给电池47充电。
如图13所示，根据实际展开的需要，如只需将柔性显示屏6部分展开时，向外拉拉柱7使柔性显示屏6部分展开，以带动转动框42转动，直至柔性显示屏6展开至所需宽度，收卷机构4及拉柱7定位于部分展开的柔性显示屏6相对的两端即可。
在基他实施例中，螺杆493相对的两端也可以分别设置有制动环，螺母491螺接于螺杆493上并位于两个所述制动环之间，当螺母491转动至抵顶制动环时，螺母491停止转动。具体的，当螺母491转动至抵顶其中一制动环时，螺母491无法再旋转，柔性显示屏6完全展开，柔性显示屏6靠近转动框42处与转动框42的外壁相切；当螺母491转动至抵顶另一制动环时，螺母491无法再旋转，柔性显示屏6完全收纳于壳体40内。
如图14所示，在另一实施例中，柔性显示屏6靠近转动框42处设置有感应器66，所述感应器66电性连接于电路板43，所述感应器66能制止驱动轴451相对于驱动件旋转。具体的，当柔性显示屏6完全展开时，即柔性显示屏6靠近转动框42处与转动框42的外壁相切，感应器60检测到感应信号并发送信号给电路板43，电路板43控制驱动轴451相对于驱动件45不再旋转，使柔性显示屏6无法再被向外拉伸，转动框42也无法转动，能防止柔性显示屏6与转动框42的连接处形成较少的弯折角，防止柔性显示屏6的损坏。
以上是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
