参见图12所示，所述轴承22位于所述第二壳体20的转子轴204围成的空间内并与所述转子轴204固定在一起，所述转子111套设于所述转子轴204的外围并与所述转子轴204固定在一起，所述转子111位于所述第一壳体10的收纳空间104内，所述轴承22套设于所述第一壳体10的定位柱103，使得所述转子111转动时可带动所述转子轴204转动，进一步带动所述夹持机构2转动。所述固定件12固定于所述定位柱103的顶端并位于所述第二壳体20的基部201的上方，以把第一壳体10限位于所述第二壳体20。
参见图13至图14所示，所述锁定件31用于和所述限位部1022配合，所述拨动件32可被操作以带动所述锁定件31移动，以使所述锁定件31处于与所述限位部1022相配合的状态或者与所述限位部1022相分离的状态。所述锁定机构3与所述限位部1022相配合时，能够锁定所述夹持机构2，以阻止所述夹持机构2的自由转动；所述锁定机构3与所述限位部1022分离时，能够解锁所述夹持机构2，所述夹持机构2能够自由转动。在其他实施方式中，所述限位部1022还可设置于所述夹持机构2，对应地，所述锁定机构3设置于所述转轴机构1。
所述锁定件31部分收容于所述第二壳体20的第一凹陷槽2010，所 述锁定件31的压接部310与所述第二壳体20抵持，以防止锁定件31脱离所述第二壳体20。所述第二壳体20的一对导引柱2012分别组装入所述锁定件31的一对通孔3105内，以引导锁定件31的上下移动。所述锁定件31的锁定部311从所述第二壳体20的贯穿孔2013内穿出。所述弹性件23的一端与所述盖板24抵持，另一端与所述锁定件31抵持。所述弹性件23部分收容于所述锁定件31的容纳槽3104，以确保弹性件23不会脱离所述锁定件31。所述锁定件31的锁定部311与所述第一壳体10的限位部1022配合，使得所述夹持机构2止转，以把所述夹持机构2限位于锁定状态。所述限位部1022包括凹槽，所述锁定部311向下移动进入所述凹槽，以锁定所述夹持机构2，所述锁定部311向上移动脱离所述凹槽，以解锁所述夹持机构2。所述第二抵持部322脱离所述第一抵持部3101后，若所述锁定部311位于相邻的两个凹槽之间，所述夹持机构2的转动能够带动所述锁定部311移动至凹槽的上方并向下落入所述凹槽。
参见图15与图16所示，解锁时，推动所述拨动件32的操作部321，所述拨动件32的第二抵持部322沿所述锁定件31的倾斜部3102移动至所述锁定件31的第一抵持部3101的下方，以支撑所述第一抵持部3101，以使得所述锁定部311处于脱离所述限位部1022的第一位置；在此过程中，所述锁定件31向上移动以脱离与所述限位部1022的配合且压缩所述弹性件23，所述夹持机构2可自由转动。所述夹持机构2处于解锁状态时，所述拨动件32的凸出部3220收容于所述第一抵持部3101的第一凹陷31010内，防止拨动件32受不当外力时移动，导致所述夹持机构2向锁定状态转换。
当需要使得夹持机构2处于锁定状态时，推动所述拨动件32的操作部321，所述拨动件32的凸出部3220从所述第一抵持部3101的第一凹陷31010内移出，所述拨动件32的第二抵持部322沿所述锁定件32的倾斜部3102移动，所述第二抵持部322脱离所述锁定件32的第一抵持部3101， 所述锁定件32受重力以及弹性件23的抵顶力的作用向下移动，使得所述锁定部311从所述第一位置运动至与所述限位部1022配合的第二位置，使得所述夹持机构2止转。所述夹持机构2处于锁定状态时，所述拨动件32的凸出部3230收容于所述锁定件32的第二凹陷3103内，防止拨动件32受不当外力时移动，导致所述夹持机构2向解锁状态转换。
所述凸出部3220也可设置于所述锁定件31，相应地，所述第一凹陷31010与第二凹陷3103设置于所述拨动件32。所述夹持机构2转动的过程中，所述第二壳体20的第二抵挡部205沿所述第一壳体10的轨道槽1020移动，当所述第二抵挡部205与所述第一壳体10的第一抵挡部1021抵持时，所述夹持机构2停止继续转动，所述夹持机构2可朝向相反的方向继续转动，以防止夹持机构2过度转动。
本发明手持云台通过锁定机构3使得所述夹持机构2可在锁定状态与解锁状态之间切换，锁定状态时，所述夹持机构2不可转动，方便组装固持件8或者拍摄装置，增加了安装的便利性；由于所述夹持机构2不可转动，组装固持件8或者拍摄装置时，可握持所述转轴机构1，相对于仅握持所述夹持机构2，增大了握持的面积，方便握持，增加了组装的便利性；同时，也可握持所述云台轴臂105，由于所述云台轴臂105比较长，更加方便握持，进一步地增加了安装的便利性。
以上对本发明实施方式所提供装置进行了详细介绍，本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施方式的说明只是用于帮助理解本发明的核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
