可选的，端口6可以为直槽，即尺寸不变的直线型凹槽，位于配合部的外部；或者端口6可以为直径缩小的收缩端口，位于配合部的外部，即相对于配合部的内径而言具有收缩的趋势。
可选的，壳体1设置有屏幕11，转轴键8的转动中心轴平行于屏幕11，且平行于壳体1的周向侧壁所在平面或者平行于周向侧壁的切平面。
请参考图1和图2，转轴键8的轴线平行与屏幕11平面设置，当屏幕11为矩形屏幕或设置屏幕11的主平面为矩形结构，壳体1的周向侧壁为若干个平面结构，依次连接围绕主平面设置时，转轴键8的轴线平行于壳体1的周向侧壁；或者，当屏幕11为圆形屏幕或设置屏幕11的主平面为圆形结构，壳体1的周向侧壁为环形面或弧面时，转轴键8的轴线平行于周向侧壁的环形面或弧面的切平面。该设置方式能够让转轴键8的转动更加便于操作。
在上述实施例的基础之上，转轴键8与安装部4中的一者设有弹性凸起7，另一者设有定位凹槽9，转轴键8转动过程中，弹性凸起7与定位凹槽9形成至少一次的卡接或脱离，以提供给操作者卡顿效果。
转轴键8转动的使用过程中，操作者能够感受到弹性凸起7滑入定位凹槽9后不易滑出的卡顿，从而确定转动至一定位置。
需要说明的是，弹性凸起7与定位凹槽9的配合位置，可以与感应装置对转轴键8的感应状态进行匹配，例如，感应装置感应到转轴键8转动至一个角度时，对应实现一次切换屏幕11，同时也对应弹性凸起7与一个定位凹 槽9的配合位置，从而使操作者感觉到切换屏幕11的确认。
通常设置为一个弹性凸起7和多个定位凹槽9，是由于凸起的结构相对复杂，凹槽的结构更容易加工，不考虑加工因素，也可以设置一个定位凹槽9和多个弹性凸起7。
优选为定位凹槽9在周向上均匀分布。可以根据使用需要合理分配定位凹槽9在周向上的设置个数和间距，以转轴键8转动用于切换屏幕11为例，设置感应装置和控制器的控制方式，使得弹性凸起7由一个定位凹槽9移动至与其相邻的另一个定位凹槽9之间的转动角度，恰好对应实现屏幕11切换的转动角度。
在一个实现转轴键8的转动感应具体实施例中，感应装置为光电传感器3，壳体1设有透光部2，透光部2位于感应装置与转轴键8之间，转轴键8的结构沿周向具有变化，以使感应装置可感应转动的转轴键8的转动。
转轴键8周向可以为锯齿结构、齿轮结构或其他具有几何特征变化的结构，感应装置为光敏元件，二者之间设置的透光部2具体为透光板、透光薄膜等，感应装置能够感应转轴键8在周向上转动，转动过程中，根据转轴键8的结构特点，感应装置可以连续性的或者阶段性的产生感应信号，并用于发送给控制器。
需要说明的是，转轴键8的操作与转动方向无关，无论顺时针或逆时针均可操作。
感应装置可选的类型多样，其中一种感应装置可以直接感应转轴键8反射设备外部的光线(自然光、灯光)，这种方式在常规使用条件下能够正常使用。
还有一个实施例中感应装置需要配合自带光源使用，自带光源可以设置在壳体上，用于(直接或透过透光部2)向转轴键8发射光线，感应装置接收转轴键8反射的光线，该方式可以用于黑暗环境的使用。
更进一步地，自带光源可以选择发射特定类型或波段的(区别于自然光)光线，感应装置用于接收特定类型(或波段)的光线，以避免由于设备外部其他自然光线的扰动造成感应装置的检测错误。
为了避免感应装置的检测错误，还可以在转轴键8的位置遮光结构，起到降低外部影响的作用。
可选的，感应装置对顺时针转动的转轴键8与逆时针转动的转轴键8的感应效果可以不同，例如，转轴键8外表面具有棘轮结构，其顺时针转动时，感应装置所感应光强或光效为递增，其逆时针转动时，感应装置所感应光强或光效为递减，从而丰富不同转动方向带来的控制效果。
在上述任意一个实施例的基础之上，透光部2(具体为透光板)与壳体1焊接连接，以形成放置感应装置的密封腔体，转轴键8位于密封腔体的外部。焊接连接紧密，不易出现间隙，焊接不会影响透光部2的透光效果，并能够起到将转轴键8隔离在壳体1外部的作用。
在上述任意一个实施例的基础之上，弹性凸起7注塑于透光部2。
可选的，透光部2为透光板。或者可以为边缘具有硬质连接框架的透光膜，透光膜需要具有一定的强度和硬度，硬质连接框架用于连接在壳体1上。
在一个具体的实施例中，转轴键8包括部分伸出于安装部4的旋转部81和连接于旋转部81并与安装部4限位卡接的柱体82，定位凹槽9设于柱体82，弹性凸起7设置于安装部4中。
旋转部81位于转轴键8的中部，其两端设置柱体82，两个柱体82的中心线共线，且均设置在安装部4中。
可选的，弹性凸起7包括Pogo Pin，即弹性顶针。Pogo Pin的底座部分可以通过注塑操作固定于透光部2，请参考图4，两个Pogo Pin均位于透光板上，弹性移动的一端朝向设置转轴键8的方向，用于配合转轴键8的定位凹槽9使用。
除了对转轴键8反射的光线感应以外，还可以通过磁感应实现上述方案，在一个具体实施例中，感应装置为感应磁场强度的磁检测装置，转轴键8的周向上设有若干个磁性部件。由于转轴键8转动过程中，磁性部件与磁检测装置的距离有变化，磁检测装置检测到的磁通量或磁场强度存在变化，能够实现对转轴键8转动状态的感应。磁性部件在轴向上的排布位置和数量可以根据实际情况进行调整，或者可以与定位凹槽9的设置数量、排布配合设置。
可选的，感应装置获取转轴键8的转动后发送给控制器，控制器可以以此控制屏幕11的切换，此外，也可以用于控制声音的调节、亮度的调节等，本申请转轴键8的作用不仅限于对屏幕11的切换作用。
除了上述各个实施例中所提供的可穿戴设备的主要结构和连接关系以 外，本申请还提供了一种可穿戴设备的组装方法，应用于上述任一项的可穿戴设备；组装方法包括：
将转轴键8可转动地安装于壳体1的安装部4，安装部4为壳体1的外部结构，且与壳体1内部不连通。
可选的，感应装置为光电感应装置，组装方法还包括：
将Pogo Pin嵌件注塑于透光部2；
将透光部2的边缘密封安装于壳体1的通孔，透光部2位于感应装置和转轴键8之间。
本申请提供的可穿戴设备的装配过程具体包括：首先，将转轴键8组装在壳体1的安装凹槽内，具体包括将转轴键8上的主体82经过安装凹槽的端口后安装于安装凹槽的内部；接着，将Pogo Pin与透光板嵌件注塑于一体，形成透光组件，使得Pogo Pin的防水效果更加可靠；然后，将透光组件与设置有转轴键8的壳体1通过超声波焊接组装，能够形成密封结构，解决基础的防水问题。
相比于按键式的切屏设备而言，本申请提供的可穿戴设备可以避免增加防水要求，相比于通过触摸屏实现切屏的设备而言，本申请可以保证防水的水平，降低出现在水下失效的可能。本申请能够简化产品气密性的测试过程，降低对组装工艺的要求，并能够节省成本，提高产品的可靠性。
除了上述各个实施例中所提供的可穿戴设备的主要结构和连接关系以外，该可穿戴设备还应该具有屏幕、穿戴件等结构，该部分内容可以参考现有技术，本文不再赘述。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
