本发明之定位机构16的具体结构不局限于上述实施方式。本发明之定位机构16也可以为其它的形式，也可以将定位机构16连接在安装部14上，当安装部14旋转至合适的位置时，通过手动的方式，通过定位机构16将安装部14固定于托盘12，例如，所述定位机构16为连接于安装部14的螺栓，相应地，在托盘12上设置至少两个螺栓孔，当安装部14相对托盘12旋转至合适位置时，将螺栓锁固在对应的螺栓孔内，从而实现安装部14与托盘12之间的固定。
另外，安装部14与托盘12也可以通过安装部14与托盘12之间的摩擦力实现定位，即安装部14贴紧托盘12，安装部14相对托盘转动的过程中，外力克服摩擦力实现转动，外力消除，通过摩擦力实现安装部14与托盘12之间的定位。
其它实施方式中，安装部14与托盘12之间相互接触的表面设置齿牙，通过齿牙之间的相互啮合，实现二者相互转动过程中的定位。
请参阅图3，所述托盘12还包括第一限位面127和第二限位面128用于限制所述安装部14的相对所述托盘12的转动范围，所述安装部14位于所述第一限位面127和所述第二限位面128之间，且在所述第一限位面127与所述第二限位面128之间相对所述托盘12转动。第一限位面127和第二限位面128限制了安装部14的转动范围，即限制了光纤连接头之光输出口的转动范围，这样避免光纤连接头转动力角度过大，只要在需要的范围内转动，提高了光输出口方向 调节的效率。
具体而言，托盘12包括前端121和后端129，所述安装部14枢接于所述托盘12的前端121，所述托盘12还包括连接器128及光纤导向结构123，所述连接器128设置于所述后端129，所述光纤导向结构123位于所述安装部14与所述连接器128之间，所述光纤连接头通过光纤F电连接至所述连接器128，所述光纤导向结构123用于定位所述光纤F走向。
本实施方式中，所述光纤导向结构123包括多个隔墙1232，所述多个隔墙1232相互平行设置，且相邻的两个所述隔墙1232之间形成通道C，以供所述光纤F通过。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
