一同参考图5、图6，所述转轴43的一端呈六角形结构，并通过此六角形结构不可转动地固定在连接臂2上。圆环状的环形磁体41安装在连接臂2上，并与转轴43同轴。夹持臂13上设有朝向所述连接臂2凸起的轴套14，轴套14中装有两个轴承15。转轴43的另一端通过上述两个轴承15与轴套14同轴连接，并且转轴43的末端通过垫片和锁紧螺母44将整个夹持臂13可转动地安装在转轴43上。所述绕组线圈42安装在轴套14上，并位于环形磁体41的内部。优选地，在本实施例中，所述绕组线圈42包括11组等角度分布设置的子线圈。
继续参考图3、图4，夹持机构还包括充电接口17、电池以及PCB板18。所述PCB板18安装在夹持臂13内部。充电接口17的一端与PCB板18电连接，另一端外露于夹持臂13。电池与PCB板18电连接且设置在夹持臂13内。上述绕组线圈42与该PCB板18电连接，并由电池供电。
本实施例的夹持机构的工作方式为：在夹持机构工作前，松开锁紧环31，锁紧环31向下(图示方向)移动，使得锁紧环31与连接臂2之间具有间隙。然后打开夹持机构的电源，云台电机即可驱动夹持臂13转动一定的角度并保证夹持臂13以及安装在夹持臂13上的手机的平衡。当云台电机断电时，手动转动夹持臂13至所需的拍摄角度后，通过拧紧锁紧环31，使得锁紧环31向上移动并抵顶连接臂2，实现锁定夹持臂13与连接臂2之间的夹角。
进一步地，如图7所示，本发明还提供一种手持云台，包括手柄5、伸缩杆(图未示)以及如上所述的夹持机构。具体地，伸缩杆的一端与手柄5连接，另一端与连接臂2转动连接。手柄5包括套接部51以及转动连接于所述套接部51下端的至少三个支撑脚52。优选地，本实施例的手柄5包括三个支撑脚。这三个支撑脚52收合后可作为手持使用，所述套接部51与收合后的支撑脚52内部形成中空腔，所述伸缩杆可收纳于所述中空腔内。在需要使用三脚架模式自拍时，将三个支撑脚52展开即可使用；在进行手持自拍或者收纳时，将三个支撑脚52转动至靠近伸缩杆，便可进行手持或收纳，十分方便快捷。
为提高手持云台的使用体验，手持云台还包括无线遥控器6，所述无线遥控器6可拆卸地安装在套接部51上。在使用三角架模式自拍时，由于使用者与手持云台的距离较远，此时通过手持无线遥控器6进行远程操控即可实现远距离拍摄；在使用手持拍摄模式时，通过使用组装在手柄5上的无线遥控器6即可进行近距离拍摄。
应当理解的是，以上实施例仅用以说明本发明的技术方案，而非对其限制，对本领域技术人员来说，可以对上述实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而所有这些修改和替换，都应属于本发明所附权利要求的保护范围。
