该具体实施方式中，进一步地，所述连接臂05的一端固定在天线架04上的具体结构为：所述天线架04包括立柱，及套设在所述立柱上、且可沿立柱升降的升降座；则所述连接臂05的一端固定在天线架04立柱上的升降座上，并可随升降座做升降移动。
在本发明第六实施方式中，如图5所示，所述第一连接件02与所述第二连接件06通过台阶式连接轴07连接。
在该具体实施方式中，进一步地，第二连接件06的侧壁设有第一安装孔62和第一定位孔63(所述第一安装孔62和第一定位孔63均为通孔，即贯穿第二连接件06两边侧壁)；所述第一连接件02的侧壁设有第二安装孔25、及垂直定位孔26和水平定位孔27；其中，所述台阶式连接轴07的一端固定在第一连接件02设有第二安装孔25的侧壁上，另一端穿过第二连接件06的第一安装孔62，所述台阶式连接轴07可在第一安装孔62中旋转活动；所述第二连接件06的第一定位孔63与第一连接件02的垂直定位孔26或水平定位孔27通过插销或螺钉可拆卸连接。
在该具体实施方式中，进一步地，所述台阶式连接轴07包括：第一台阶71、与第一台阶71相连并穿装于第一安装孔62内的第二台阶72、与第二台阶72相连的第三台阶73，其中，所述第一台阶71与第一连接件02设有第二安装孔25的侧壁通过螺钉74螺纹连接；所述第二台阶72贯穿第一安装孔62，所述第三台阶73穿出第一安装孔62，使得台阶式连接轴07可在第一安装孔62中旋转活动。
在该具体实施方式中，进一步地，所述台阶式连接轴07还包括固定板75，所述固定板75套设在第三台阶73上，所述固定板75与连接臂05通过螺钉74螺纹连接，使装置更加稳固。

可以理解的是，由于第二连接件06固定在连接臂05上，第二连接件06与第一连接件02通过台阶式连接轴07活动相连，只需要第二连接件06的第一定位孔63与第一连接件02上的垂直定位孔26或水平定位孔27相连，即可实现第一连接件02不同方位的改变，即改变插销 或螺钉穿插在垂直定位孔26、水平定位孔27的不同状态来改变第一连接件02的位置状态，进而通过第一连接件02带动台阶式连接轴07绕台阶式连接轴07的轴线旋转。如图4所示该状态下，第一连接件02上的天线03水平放置；若改变插销或螺钉穿插位置，可将第一连接件02上的天线03垂直放置(即图6中非金属气缸01的位置)。
在本发明第七实施方式中，如图7是非金属位置传感器08的剖面图；本发明实施例3提供的旋转角度可调天线装置002还包括非金属位置传感器08，所述台阶式连接轴08进一步与非金属位置传感器08连接；其中，所述非金属位置传感器08具体包括：

可以理解的是，本实施方式中，所述第四密封圈8124将第二缸体81分割为第二缸体上腔室811和第二缸体下腔室812。
当人工旋转第一连接件02，将天线03在垂直放置状态或水平放置状态之间切换，则第二连接件06带动台阶式连接轴07旋转，从而带动非金属位置传感器08的连接杆伸缩移动，达到状态1(如图7所示)或状态2(如图8所示)，导致不同气孔的导通，形第一或第二气压信号，并触发外部气电转换装置的微动开关，所述的外部气电转换装置将第一或第二气压信号转化成第一或第二电信号，则当外部控制设备接收到第一或第二电信号时，可判断、检测和/或显示天线处于垂直放置状态或水平放置状态。
可以理解的是，本发明中所述的“上”、“下”并不代表绝对空间。
值得注意的是，为了降低天线架本身对测试的干扰，本发明各实施方式中的非金属气缸01、第一连接件02、天线03、天线架04的支柱及升降座、连接臂05、第二连接件06、非金属传感器08、台阶式连接轴07及这些组件之间的连接部件均采用非金属材质制备而成。

本发明实施例4提供了一种旋转角度可调天线系统003，包括本发明实施例2提供的旋转角度可调天线装置001，还包括与非金属气缸01相连的第一输气装置、与第一输气装置相连 的控制装置，所述输气控制装置用于：发送第一或第二输气指令给第一输气装置；所述第一输气装置用于：当接收输气控制装置发送的第一输气指令时，向非金属气缸06的第一通孔113输气，使得第一活塞杆14向第二通孔114推进，当接收输气控制装置发送的第二输气指令时，向非金属气缸06的第二通孔114输气，使得第一活塞杆14向第一通孔113推进。可以理解的是，通过所述非金属气缸01的第一活塞杆14的伸缩带动旋转套做0-90°旋转，进而带动天线做0-90°旋转。进一步地，所述输气控制装置具体用于控制进入所述非金属气缸第一通孔或第二通孔中气流的方向及大小，进而控制所述非金属气缸的第一活塞及第一活塞杆做伸缩移动的方向和速度。
实施例5一种旋转角度可调天线系统
图9是本发明实施例5提供的旋转角度可调天线系统004的结构示意图。

可选地，由于控制设备可判断天线处于水平放置状态还是垂直状态，可进一步通过对本发明的控制设备的控制程序进行预设，比如，当控制设备判断天线处于水平放置状态，预设控制设备中的控制程序不输出控制天线向某个方向的移动指令，从而避免无效移动。
具体地，本发明提供旋转角度可调天线系统004还包括第二输气装置，所述第二输气装置用于给非金属位置传感器08的气缸输气，具体地，本发明实施例提供的输气装置用于给第二非金属位置传感器08的第一径向气孔821、所述第二径向气孔822、第三径向气孔823中的进气孔输气。
本发明还可有其它实施方式，凡是采用同等替换或等效变换形成的技术方案，均落在本发明要求的保护范围之内。
