具体实施方式
请参照图1至图4所示，其显示出了本发明之实施例的具体结构；所述伸缩管式车载后背支架，包括有安装杆和装设于安装杆上以用于固定移动终端的的安装部。
其中，所述安装杆包括有连接头10和分别连接于连接头10左、右端的两个连接管（分别如图示20、30），两个连接管的外端均连接有卡持部（分别如图示41、42），至少一个连接管30内部装设有伸缩弹簧，相应的卡持部42则受伸缩弹簧作用而相对连接管30可左右位移式设置。本实施例中，所述伸缩弹簧为压力弹簧50，所述卡持部42具有向外开口的U形夹401，所述U形夹401覆设有U形硅胶扣403。
所述卡持部41、卡持部42的内侧均连接有插接段402，所述插接段402伸入相应连接管的外端内部。所述插接段402的外表面、连接管的内表面，两者中其一设置有凸肋61，另一设置有凹槽62，所述凸肋61适配于凹槽62内，所述凸肋61、凹槽62均与连接管同轴向延伸设置。
所述安装部包括有装设于安装杆上的转动杆件70、安装于转动杆件70上的360度转动球头组件80及装设于360度转动球头组件80上的夹头90；其中，所述转动杆件70具有中空杆体段71和连接于中空杆体段71一侧的枢接口72，中空杆体段71套接于安装杆上，枢接口72的上、下侧均设置有锁固壁73，锁固壁73上开设有第一连接孔731，前述360度转动球头组件80具有枢接座81，其枢接座81上开设有第二连接孔811，枢接座81伸入枢接口72内，通过螺丝701依次穿过上侧的第一连接孔731、第二连接孔811及下侧的第一连接孔731，螺丝701的下端适配有调节螺母702，此处的螺丝701设置有调节柄部以方便手动调节。
所述连接头10具有中间限位台11和自中间限位台11两侧分别往外延伸的两个连接轴段(如图示连接轴段12、连接轴段13)；一个连接管20套设于其中一个连接轴段12的外围，另一个连接管30套设于中间限位台11的外围，伸缩弹簧（图示：压力弹簧50）一端套设于另一个连接轴段13的外围，伸缩弹簧另一端连接于相应的卡持部42；前述中空杆体段71的一端往内径向延伸形成有环形止挡部74，中空杆体段71套设于前述另一个连接管30的外围，环形止挡部74限位于前述另一个连接管30的内侧端。
当然，所述伸缩弹簧也可以设计为拉力弹簧，这样，将前述卡持部设计为具有向内开口的勾部，在使用时，将其中一个或两个卡持部往外拉，使两个卡持部分别勾于两个金属杆的外侧，利用弹簧拉力形成安装杆于车座头枕金属杆上的定位。这种勾部式设计相比前述U形夹结构设计而言，安装杆的整体体积会稍大一些，因此，在实际设计应用时可以依据实际需优选前述如图1至图4所示的实施方案。
综上所述，本发明的设计重点在于，其主要是通过将安装杆设计为可弹性伸缩结构，其装设应用变得极其简单，直接将安装杆卡持于车座头枕金属杆100上即可，拆卸时将一卡持部42沿内侧移动（或将卡持部41、卡持部42同时往内移）即可将整个安装杆取出；同时，安装杆整体结构简单、紧凑，稳定性佳。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
