具体实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，下面结合附图，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本实用新型，并不用于限定本实用新型。
请参阅图1至图4，一种组合三脚架，包括起到中轴作用的子架1和母架2，所述子架1和所述母架2通过主连接架3组合在一起；
所述子架1的一端与所述主连接架3相穿插，所述子架1能够沿着m轴的方向往返运动；所述子架1的另一端安装有用于保证所述子架1刚度和平行度的Y型支撑架4；
所述母架2与所述主连接架3通过螺旋件5调节或固定展开角度，所述母架2通过外扳扣锁6完成伸缩态。
三根所述中轴腿101均匀布置在三根所述主架腿201的外侧，主要组合方式如图16至图20所描述。
请参阅图7，所述母架2包括三根主架腿201，每根所述主架腿201包括多根同轴心相套接且能够沿着所述主架腿201的长度方向伸缩的伸缩腿202；相邻所述伸缩腿202相交处通过外扳扣锁6相连接；
最底端的所述伸缩腿202的底端与管脚203相套接，最顶端的所述伸缩腿202的顶端通过所述旋转件5与所述主连接架3活动相接。
在一种可能的实现方式中，多根伸缩腿202为五根，第一伸缩腿202a内套接有第二伸缩腿202b，第二伸缩腿202b内套接有第三伸缩腿202c，第三伸缩腿202c内套接有第四伸缩腿202d，第四伸缩腿202d内套接有第五伸缩腿202e。
并且第二伸缩腿202b、第三伸缩腿202c、第四伸缩腿202d和第五伸 缩腿202e均可以沿着第一伸缩腿202a的长度方向往返运动。从而使得可伸缩腿202伸长或缩短。
在一种可能的实现方式中，多根伸缩腿202为五根，五根所述伸缩腿202分别为第一伸缩腿202a、第二伸缩腿202b、第三伸缩腿202c、第四伸缩腿202d和第五伸缩腿202e，所述第五伸缩腿202e与所述第四伸缩腿202d相离的一端与管脚203相套接，所述第一伸缩腿202a与所述第二伸缩腿202b相离的一端通过所述旋转件5与所述主连接架3活动相接。
请参阅图8至13所述外扳扣锁6包括一体化弹性外环604，所述一体化弹性外环604分别与每根所述伸缩腿202的a端相套接，所述一体化弹性外环604包括弹性带605，所述弹性带605的悬空端设有用于与板扣臂606相紧，且用于紧固所述伸缩腿202的弹性带支点凸起6051，与所述弹性带支点凸起6051相对应的所述外扳扣锁6上对称设有滑动槽孔607。
所述板扣臂606与所述弹性带支点凸起6051相邻的一端设有扳扣前臂606a，所述板扣前臂606a上安装有板扣轴孔606b，所述扳扣臂606与所述弹性带支点凸起6051相离的一端设有扳扣尾扣606c；
所述扳扣轴孔606b通过转轴与所述滑动槽孔607相穿设；
每根所述伸缩腿202与所述外扳扣锁6相离一端的外表面设有防止所述伸缩腿202彼此之间相脱离的止滑片404。
止滑片404的作用为：拉伸下一级伸缩腿202直至止滑片404的端部与衬套601的端部相抵接，按紧或板扣臂606从而使衬套601与对应的伸缩腿402相紧固或松弛，从而完成相伸缩腿402的伸缩或固定。
在一种可能的实现方式中，转轴穿过板扣轴孔606b并插入滑动槽孔607中，由于滑动槽孔607为腰孔，转轴能够在滑动槽孔607内运动。
由于扳扣前臂606a的端部设有凸起，转轴转动时，转轴在滑动槽孔607内滑动，从而扳扣前臂606a的凸起挤压弹性带支点凸起6051，从而使弹性带605紧压住伸缩腿202，使一体化弹性外环604与伸缩腿相扣紧，保持相邻的伸缩腿之间的稳定性；
或使弹性带605与伸缩腿保持松弛的状态，使一体化弹性外环604与伸缩腿处于松弛的状态，使相邻的伸缩腿之间处于滑动的状态。
锁扣的运动状态为：
释放状态：向外搬动板扣臂606，在杠杆原理的作用下，转轴在滑动槽孔607内移动到止点，继续转动板扣臂606，板扣臂606后退，在材料弹力的作用下，弹性带支点凸起6051退回到自然状态。此时弹性带605不会对弹性带支点凸起6051形成压力，相邻的伸缩腿可以自由滑动。
锁紧状态：反向压下板扣臂606，板扣前臂606a的凸起首先接弹性带支点凸起6051，继续压板扣臂606，则会推动转轴顺势在滑动槽孔607内移动到下支点，在继续压板扣臂606，在杠杆原理的作用下，板扣臂606会推动弹性带支点凸起6051向前移动，从而压紧弹性带605，达到挤压衬套601，从而锁紧相邻的伸缩腿。
请参阅图5和图6，所述子架1包括三根中轴腿101，所述主连接架3上分布设有三个楔形孔301，三根所述中轴腿101分别与三个所述楔形孔301一一对应相穿设；
所述楔形孔301内安装有楔形片302，所述主连接架3的外圆周上旋转套接有环套303，所述楔形片302与所述环套303的内壁滑动相连接，通过旋转所述环套303以推动所述楔形片302上下运动，当向下运动时，由于楔形的作用，楔形片302向内横向运动，将子架的中轴腿101压向内壁 304，实现锁紧对中轴腿101的，方向运动则释放。
请参阅图15，所述主连接架3带有三个铰接棘轮305，分别通过销轴501连接三个旋转件5，旋转件内通过销轴501放置棘爪扳手502，销轴上同时放置了同轴心扭簧503以保持棘爪扳手的工作位置；每条所述伸缩腿202的a端均设有与衬套凸起603相插接的衬套槽口208，所述衬套凸起603设置在衬套601上，所述衬套601上开设有对称且交错设置的衬套缝602和所述衬套凸起603。
请参阅图14、图5和图2，三根所述中轴腿101之间安装有所述Y型支撑架4，所述Y型支撑架4的每条边分别与三根所述中轴腿101的安全 尾塞相嵌接，以对所述子架1起到辅助支撑和限位作用；同时Y型支撑架4设有对接螺纹，与所述母架2对接，以实现所述母架2作为独立的三脚架。
当子架脱离母架时，需要将Y型支撑架4取出，与主架连接架3的螺纹306对接，成为主架的云台对接载台，完成主架作为三脚架的独立功能。
三根所述中轴腿101能够插入三根所述主架腿201之间的侧间隙，以使三根所述中轴腿101和三根所述主架腿201之间紧密且交错排布。从而形成最紧凑的空间结构。图16至图20为下图中的断面设计的例子。
