以下将配合附图及实施例来详细说明本申请的实施方式，藉此对本申请如何应用技术手段来解决技术问题并达成技术功效的实现过程能充分理解并据以实施，以下结合附图对本发明的结构做进一步说明。
实施例1
图1为本申请的调节装置的分解结构示意图，如图1所示。
本申请提供了一种调节装置，其包括：转轮10、瞳距调节组件及物距调节组件。
其中，瞳距调节组件包括：第一螺杆20、与第一螺杆20啮合连接 的瞳距调节执行机构。
物距调节组件包括：第二螺杆30、与第二螺杆30啮合连接的物距调节执行机构。
转轮10的中心设有通孔11。通孔11、第一螺杆20及第二螺杆30同轴，转轮10能沿轴线方向在第一螺杆20与第二螺杆30上移动。
转轮10移动至第一螺杆20上时，转轮10与第一螺杆20通过连接结构连接，转轮10能带动第一螺杆20一同转动。转轮10移动至第二螺杆30上时，转动与第二螺杆30通过连接结构连接，转轮10能带动第二螺杆30一同转动。
转轮10带动第一螺杆20一同转动时，第一螺杆20可控制瞳距调节执行机构进行瞳距调节。转轮10带动第二螺杆30一同转动时，第二螺杆30可控制物距调节执行机构进行物距调节。本申请提供的技术方案，通过转换转轮10与第一螺杆20或第二螺杆30的连接，使得仅通过转轮10即可控制瞳距调节执行机构及物距调节执行机构，进而进行瞳距调节或物距调节。调节机构的结构简单，占用空间小，而且操作部件少，仅通过一个部件即可实现瞳距或物距调节。操作过程简单方便，提高了佩戴的舒适度，能够让不同视力的使用者极其方便地使用头显设备。
下面对于本申请提供的调节装置做进一步的详细介绍。
参见图1至3，连接结构包括：弹性插件12及与弹性插件12配合的凹槽13。弹性插件12包括但不限于为弹性卡销或弹性卡珠。
其中，一种可实现方式是，弹性插件12设置在转轮10的通孔11的孔壁上，第一螺杆20和第二螺杆30上设有凹槽13。
以弹性插件12为弹性卡珠为例，举例来说，弹性卡珠包括固定件、弹簧及滚珠。转轮10的通孔11的孔壁上设置有连接槽53。固定件固定连接在连接槽53内，弹簧设置在固定件及滚珠之间。滚珠设置在连接槽53的槽口处，连接槽53的槽口的尺寸小于滚珠的尺寸，滚珠可部分伸出槽口。另外，也可省去固定件，弹簧固定在连接槽53内，滚珠设置在槽口与弹簧之间。
弹性卡珠可为多个，周向均匀分布在转轮10的通孔11的孔壁上。例如，弹性卡珠有两个，分别为可以分为第一弹性卡珠及第二弹性卡珠，第一弹性卡珠及第二弹性卡珠沿转轮10的通孔11的轴向方向并排设置。相应地，凹槽13也为多个，多个凹槽13均匀周向分布在第一螺杆20上与弹性卡珠相配的位置及多个凹槽13均匀周向分布在第二螺杆30上与弹性卡珠相配的位置。
以转轮10与第一螺杆20连接为例，转轮10在第一螺杆20上移动时，弹性卡珠中的滚珠被压缩进第一螺杆20的连接槽53内。当转轮10移动至凹槽13位置时，弹性卡珠中的滚珠伸入凹槽13内，转轮10转动时可通过弹性卡珠驱动第一螺杆20转动。
当然，连接结构除了上述的设置方式之外，还包括另一种可实现方式，第一螺杆20和第二螺杆30上均设有弹性插件12，转轮10的通孔11的孔壁上设有凹槽13。上述两种方式可以结合使用，此处不做具体限定。
本申请中，为实现瞳距的调节，一种可实现方式是，参见图1和图4，瞳距调节执行机构包括：第一齿轮21、第二齿轮22、第一齿条23和第二齿条24。其中，第一齿轮21和第二齿轮22通过直杆连接。第一齿轮21与第一螺杆20啮合。第一齿条23与第二齿条24平行。第二齿轮22处于第一齿条23与第二齿条24之间，且分别与第一齿条23和第二齿条24啮合。
具体地，转轮10与第一螺杆20通过连接结构连接，转轮10带动第一螺杆20一同转动时，第一螺杆20带动第一齿轮21转动，第二齿轮22与第一齿轮21同步转动。转轮10在向不同方向(顺时针或逆时针)转动时，可驱动第二齿轮22向不同的方向转动。第二齿轮22向不同的方向转动时带动与其啮合的第一齿条23和第二齿条24向相背或相向的方向移动。在实际使用时，第一齿条23和第二齿条24分别连接在不同的镜筒上，第一齿条23和第二齿条24向相背或相向的方向移动时，进而实现不同镜筒之间的瞳距调节。
继续参见图4，第一螺杆20与连接第一齿轮21及第二齿轮22的直 杆垂直设置，第一螺杆20向第一齿轮21输出动力的方式包括多种，一种可实现方式是，第一螺杆20包括螺纹齿，第一齿轮21为直齿轮。螺纹齿轮转动时可带动直齿轮转动。另一种可实现的方式是，第一螺杆20包括为锥齿，第一齿轮21为锥齿轮。
第二齿轮22与第二齿轮22啮合的第一齿条23及第二齿条24均为直齿轮，可保证瞳距调节时移动的平滑性。
本申请中，为实现物距的调节，一种可实现方式是，参见图1和图5，物距调节执行机构包括：传动杆31、执行杆32及推动件33。其中，传动杆31上设有第一锥齿轮34及与第二螺杆30啮合的第三齿轮35。执行杆32上设有第一锥齿轮34啮合的第二锥齿轮36。推动件33与执行杆32螺纹连接。
第二螺杆30带动第三齿轮35转动，第三齿轮35带动第一锥齿轮34旋转，第二锥齿轮36带动执行杆32旋转，使得推动件33沿执行杆32的轴线方向移动。
具体地，转轮10与第二螺杆30通过连接结构连接，转轮10带动第二螺杆30一同转动时，第二螺杆30带动第三齿轮35转动，第一锥齿随第三齿轮35同步转动，第一锥齿驱动第二锥齿转动，从而实现执行杆32转动。转轮10在向不同方向(顺时针或逆时针)转动时，可驱动执行杆32向不同的方向转动。执行杆32向不同的方向转动时，可驱动推动件33沿执行杆32的轴线方向往复移动。在实际使用时，推动件33与显示器52连接，在推动件33沿执行杆32的轴线方向往复移动时，可带动显示器52沿执行杆32的轴线方向做往复运动，实现显示器52的物距的调节。
继续参见图5，第二螺杆30与传动杆31垂直设置，第二螺杆30向传动杆31输出动力的方式包括多种，一种可实现方式是，第二螺杆30包括螺纹齿，第三齿轮35为直齿轮。另一种可实现方式是，第二螺杆30及第三齿轮35均为锥齿轮。
传动杆31与执行杆32垂直设置，除了通过锥齿方式输出动力外， 还包括第一锥齿轮34为螺纹齿，第二锥齿轮36为直齿轮。
需要说明的是，推动件33的数量可为一个或多个，执行杆32的数量与推动件33的数量一致。在实际使用中，推动件33与显示器52连接，为了保证显示器52能够平稳的进行移动，推动件33优选地为双数，以第三齿轮35为中心，对称分布在传动杆31上。
参见图1和图6，为方便用户切换转轮10与第一螺杆20或第一螺杆20连接，调节装置还包括：转轮推板40。
转轮推板40的一种可实现的方式是，转轮推板40上开有转轮孔41，转轮孔41的两相对侧边设有平行的两推板42。转轮10通过转轮孔41进入两推板42之间的空隙，且转轮10与两推板42平行。
用户通过转轮推板40对转轮10进行操作，从而切换转轮10与第一螺杆20或第一螺杆20连接。为了方便用户在切换时能够准确获知转轮10的连接状态，在转轮推板40上可设置有指示标记，例如，在转轮孔41的两相对侧边设置指示文字或图形。
实施例2
图7为本申请的头显设备的分解结构示意图，参见图7。

下面通过具体使用场景来介绍头显设备如何进行瞳距及物距调节的。
参见图8至图11，需要调节头显设备的瞳距时，将转轮10推动至图10中所示的位置，此时，参见图11，转轮10与第一螺杆20连接，转轮10上的弹性插件12伸入凹槽13内。此时，顺时针或者逆时针转动转轮10，转轮10带动第一螺杆20转动，第一螺杆20带动第一齿轮21转动，第二齿轮22与第一齿轮21同步转动，第二齿轮22在向不同的方向转动时带动第一齿条23及第二齿条24相背或者相向移动，从而第一齿条23及第二齿条24带动第一镜筒50及第二镜筒51相背或相向移动。停止旋转转轮10，则完成瞳距的调节。
需要调节物距时，参见图8及图9、图12及图13，将转轮10推动至图12中所示的位置，此时，参见图14，转轮10与第二螺杆30连接，转轮10上的弹性插件12伸入凹槽13内。此时，顺时针或者逆时针转动转轮10，转轮10带动第二螺杆30转动，第二螺杆30带动传动杆31转动，传动杆31带动执行杆32转动，执行杆32在向不同的方向转动时带动推动件33沿执行杆32的轴线方向做直线往复运动。停止旋转转轮10，则完成物距的调节。
继续参见图7，头显设备还包括：前壳54、带有显示口的隔板、带有操作孔的中壳55及带有镜孔的后壳56。
