本实施例中，内套管42定位于支撑块上是其中一种形式，另一种形式为支撑块41上固设有多边形定位件，如四边形或方形定位件，内套管42下端与该多边形定位件配合连接，内套管42下端的形状与多边形定位件的形状相适配，如四边形或方形，以使内套管42相对多边形定位件周向定位，进一步的，螺纹套43形状亦可为四边形或方形，其可套设于内套管42上端，由内套管42内壁对其限位，使其被周向定位，具体的，螺纹套43可包括内置于内套管42内的内置部位431及径向延伸的外沿部位432，外沿部位432配置于内套管42上端，螺纹套43内壁上具有内螺纹，如图2所示。
作为更为细化的特征，外沿部位432的外径与内套管42的外径相适配，外沿部位432与内套管42的两个相对壁相齐平。
具有若干螺杆单元5，螺杆单元5螺纹配置于螺纹套43上，具有外螺纹，其与螺纹套43螺纹连接，当其转动时，因螺纹套43受制于内套管42、支撑块41的限定，使其无法动作，从而使螺杆单元5在旋转过程中向上提升，而螺杆单元5又包括有或设置有可带动底座同步动作的配合部位，因此，在螺杆单元5向上提升时，能够带动底座1一端随之提升，已实现底座1的抬升；底座1的下降原理相似。
对于螺杆单元5与底座1之间的配合，本实施例中，螺杆单元5包括螺杆上部51和螺杆下部52，螺杆上部51的外径小于螺杆下部52的外径，螺杆上部51可穿过传动组件箱体3上的通孔31并延伸至传动组件箱体3内，螺杆上部51的外径可与通孔31的外径相适配，而螺杆下部52的外径大于通孔31的直径，其无法穿过该通孔31，因此，螺杆下部52上沿形成所述配合部位，在螺杆单元5往上提升时，螺杆下部52上沿提供接触位，带动底座1同步抬升；而螺杆单元5下降时，结合重力作用，底座1可随之下降。
因螺杆单元5旋转会与相应接触的面产生摩擦，从而可在螺杆上部51上套设平面轴承61，平面轴承61具体可位于螺杆上部51位于传动组件箱体3外的部位上，位于传动组件箱体3下方，当然，平面轴承61的外径需大于通孔31外径，以代替螺杆下部52与传动组件箱体3底面相接触，进一步的，传动组件箱体3底面可开设用于容置平面轴承61的槽体，如图2所示。
本实施例中，在螺杆上部51位于传动组件箱体3内的部位上设置有轴承62，具体的，传动组件箱体3内底面上开设相应槽体，轴承62容置于该槽体处，如图2所示。
而为提升底座1升降的稳定性，可在外套管2与内套管42之间设置滑套7，如图2所示，滑套7滑动套设于内套管42上，滑套7可通过紧固件与外套管2固连。
对于传动相关的部件，本实施例中，螺杆单元5与驱动单元8传动连接，驱动单元8作为动力源，设置于底座1上，驱动单元8与螺杆单元5可为直接传动连接，如直接带动螺杆单元5旋转；又可通过若干传动部件的形式使两者传动连接，如在两者之间设置传动轴9或若干锥齿轮的形式。
如图1-图4所示，本实施例中，驱动单元8为电机，其可设置于底座1纵向管件上或纵向管件上延伸的部件上，其输出轴81端延伸入对应的传动组件箱体3内，输出轴81端具有第一锥齿轮82，螺杆单元5上端具有与第一锥齿轮81传动配合的第二锥齿轮53。
上述结构已可实现驱动单元8带动一套升降机构实现升降，而要使两套同步动作，本实施例中，如图1、图3所示，在两套升降机构之间设置一传动轴9，即两个外套管2上的螺杆单元5通过该传动轴9传动连接，以使两者可同步动作。
回到上述内容，第一锥齿轮82与第二锥齿轮53传动配合，对应的，传动轴9两端均具有第三锥齿轮91，其两端的第三锥齿轮91分别位于对应的传动组件箱体3内，并与对应的第一锥齿轮82和/或第二锥齿轮53传动配合。
由此，驱动单元8作为动力源，其可带动其输出轴81及第一锥齿轮82转动，第一锥齿轮82转动促使第二锥齿轮53及第三锥齿轮91转动，其中，第二锥齿轮53转动带动螺杆单元5转动；第三锥齿轮91转动带动传动轴9转动，实现两端的螺杆单元5同步动作。
位于远离驱动单元8侧的螺杆单元5相关部件的布局可参见图4所示。
实施例2：
本实施例相较于实施例1，区别在于驱动单元的布置位置不同以及因布置位置不同而需要有的相关传动部件，其余均相同。
参见图4-图8，本实施例中，底座1一端具有至少三个外套管2，位于两侧的外套管2与实施例1中相同，其内部具有内套管42、螺纹套43、螺杆单元5等部件，而位于中间的中部外套管2a，其用于安装驱动单元8，同样的，驱动单元8可为电机。
用于安装驱动单元8的中部外套管2a与其他外套管2具有不同之处，其底部具有用于支撑驱动单元8的底板2b，底板2b可与中部外套管2a一体成型，中部外套管2a底座同样可设置有支撑块41，如图6所示。
本实施例中，用于安装驱动单元8的中部外套管2a上同样可装配有传动组件箱体3，驱动单元8对应的第一锥齿轮81位于该传动组件箱体3内，传动轴9穿设于该传动组件箱体3处，传动轴9位于该传动组件箱体3内具有额外的锥齿轮，如第四锥齿轮92，其与驱动单元8的第一锥齿轮81传动配合。
 本实施例中，驱动单元8采用内置布局，通过传动轴9将力传输至两端的螺杆单元5处，已实现底座1的升降。
实施例3：
本实施例相较于实施例1，区别在于驱动单元的布置位置不同以及因布置位置不同而需要有的相关传动部件，其余均相同。
参见图4、图9及图10，本实施例中，底座1一侧两端分别具有对应的外套管2、内套管42、螺纹套43、螺杆单元5等升降用部件，驱动单元8可设置于两个外套管2之间的横管上或设置于该横管上的延伸部件上，在用于传动连接两个螺杆单元5的传动轴9上具有皮带轮，皮带轮可带动传动轴9同步转动，两者周向定位，对应的，驱动单元8的输出轴81上同样具有皮带轮，两个皮带轮上安装传动皮带10，驱动单元8亦可为电机。
即本实施例中，驱动单元8通过传动皮带10与传动轴9传动连接，再由传动轴9两端对应的第三锥齿轮91与螺杆单元5上端的第二锥齿轮53传动连接，如此带动两个螺杆单元5同步动作，实现底座1的升降。
实施例4：
本实施例相较于实施例1，区别在于驱动单元为手摇机构，其余均相同。
参见图1-图10，本实施例中，传动轴9至少有一端延伸至对应的传动组件箱体3外，再由与其形状相适配的手摇机构（图中未示意）摇动其转动，从而带动相应的螺杆单元5转动实现底座1的升降。
