请参阅图1至图2，本实用新型一种透镜调节装置包括固定支架106、透镜支架103以及连接件以及紧固弹片102，透镜支架103设有安 装透镜104的区域；其中，固定支架106和透镜支架103分别设有第一导向区域和第二导向区域，连接件一端活动连接于固定支架106的第一导向区域，连接件另一端活动连接于透镜支架103的第二导向区域，使得在外力下透镜支架103和固定支架106可在至少两个方向上相对位移；透镜支架103通过紧固弹片102安装在固定支架106上。
本实施例的透镜调节装置使用导向区域和连接件的相对滑动取代了通常所用的导轨，来调节透镜104的位置。透镜支架103用于安装固定透镜104，固定支架106用于安装透镜支架103，固定支架106与透镜支架103之间的安装方式为通过设置紧固弹片102夹持两者而使两者紧密贴合。紧固弹片102用于固定支架106与透镜支架103固定为一体前对两者进行夹紧，限制固定支架106与透镜支架103在两者接触面的垂直方向上的运动。透镜支架103上的第一导向区域和固定支架106上的第二导向区域通过连接件互相活动连接，第一导向区域用于调节透镜104移动的第一方向，第二导向区域用于调节透镜104移动的第二方向，当对透镜支架103施加外力时，根据施加的力的方向，透镜支架103可通过第一导向区域和连接件的相对运动在第一方向上移动，也可通过第二导向区域和连接件的相对运动在第二方向上移动，从而使透镜104在不同方向上位移，少数几次调节后即可准确定位透镜104。以下将对固定支架106、透镜支架103和连接件的具体结构做详细说明。
可选的，第一导向区域设有沿第一方向的第一轨道，第二导向区域设有沿第二方向的第二轨道，连接件一端可滑动装配于第一轨道，连接件另一端可滑动装配于第二轨道。第一轨道和第二轨道可以是滑槽或长孔，只需供连接件滑动，即可带动透镜104产生位移，完成透镜104的位置调节。
可选的，第一轨道是贯通固定支架106且沿第一方向设置的第一腰型孔108，第二轨道是贯通透镜支架103且沿第二方向设置的第二腰型孔109，第一方向垂直于第二方向，连接件是依次穿过第一腰型孔108和第二腰型孔109的紧固螺钉107。腰形孔为两端是半圆弧，中间是平行平面的通孔，紧固螺钉107在相互垂直的第一腰型孔108和第二腰型 孔109内滑动时，即是向垂直的第一方向和第二方向上移动，透镜104经过两方向的调节可以到达预设的位置。
可选的，第一腰型孔108和第二腰型孔109的数量可以为一组也可以为多组，当第一腰型孔108和第二腰型孔109均为一个时，两者的位置均分别设于固定支架106和透镜支架103的中心线上，当为多组时，以固定支架106和透镜支架103的中心线对称分布。由于紧固螺钉107是穿过第一腰型孔108和第二腰型孔109连接固定支架106和透镜支架103，上述设置可以达到力的平衡，在调节透镜104位置时不受透镜支架103本身重力的影响。
本实施例中设置的紧固弹片102除用于限制固定支架106与透镜支架103在两者接触面的垂直方向上的运动之外，同时还对第一腰型孔108和第二腰型孔109的位置进行预调整，使紧固螺钉107可以从两者之间穿过。

本实施例中的透镜调节装置还包括锁定弹片101及紧固件107，锁 定弹片101上与第一腰型孔108和第二腰型孔109对应位置设有通孔115，紧固件107依次穿过第一腰型孔108、第二腰型孔109和通孔115，将透镜支架103和固定支架106固定于锁定弹片101上，紧固件107可以为螺栓。锁定弹片101用于透镜支架103在垂直面上的固定，将锁定弹片101、透镜支架103和固定支架106固定为一体，使透镜支架103无法在垂直面上运动，保证锁定弹片101和固定支架106不会脱离，但在接触面上可以相对滑动。
本实施例中的透镜104通过透镜弹片105固定于透镜支架103上；透镜弹片105和透镜支架103上均设有多个相应的螺栓孔111，两者通过螺栓可拆卸式连接。固定支架106上与对应安装透镜104的区域处对应位置开设有通光孔112，用于容纳透镜104及透镜弹片105。透镜弹片105为环形固定件，透镜104安装于环形中间，透镜弹片105通过螺栓与透镜支架103固定。通光孔112开设于固定支架106中部，直径大于或接近于透镜弹片105外边缘的直径，使之可以容纳透镜弹片105。
请参阅图3和图4，本实施例中的透镜支架103上还设有调节孔113，固定支架106与调节孔113的位置相对应处形成缺口114，使调节孔113外露与调节件连接。本实用新型的透镜调节装置需借助外部的调节件对透镜支架103施加力，使透镜支架103可以在第一方向和第二方向上移动，该调节件可以使用螺丝刀、扳手或其它硬质物，插入调节孔113内施加相应的力，即可以使透镜支架103滑动，简单方便的调整透镜支架103的位置。调节孔113通常设于透镜支架103的上部，为不遮挡调节孔113，固定支架106在相应位置处形成了缺口114，该缺口114在两者夹紧时使调节孔113外露，便于调节件进行位置调节。另外，在透镜支架103上设置调节孔113，调节件插入调节孔113内即可带动透镜104向不同方向位移，满足透镜104在一侧调整不同方向的使用需求。
本申请中调节孔113的数量为多个，且多个调节孔113以透镜支架103的中垂线为中心线对称分布。为便于调节，本实施例中调节孔113的数量优选为两个，分别分布于透镜支架103的两侧。当需要使透镜支架103向左侧移动时，调节件插入位于右侧的调节孔113内施加力；当 需要使透镜支架103向右侧移动时，调节件插入位于左侧的调节孔113内施加力，调节件插入离调节目标较远的调节孔113内时力矩较大，施加较小的力即可使透镜支架103移动，调节时更省力。
使用本实用新型的透镜调节装置，通过一个连接件活动连接两个导向区域，固定支架和透镜支架通过导向区域在连接件上移动从而带动透镜位移，分别进行透镜不同方向的位置调节，取代了常用的两套导轨或滑轨的调节结构，结构简单，降低制造成本且便于操作。
以上仅为本实用新型的实施方式，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
