具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本实用新型的一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本实用新型保护的范围。
请同时参阅图1-5所示，本实用新型提供一种方棒固定装置100以及应用该方棒固定装置100的光学设备(未图示)。
方棒固定装置100包括支架1、弹性件2以及光栅3，弹性件2可拆卸连接于支架1，光栅3固定于支架1。
光学设备包括方棒固定装置100以及方棒4，方棒4固定支撑于方棒固定装置100。
具体的，支架1用于支撑固定方棒和光栅3，弹性件2跨接于支架 1并将方棒4向支架1的方向抵压并形成固定，方棒4与光栅3相对间隔设置。
在本实施方式中，支架1包括相互垂直连接的第一固定板11和第二固定板12、同时连接于第一固定板11和第二板12同一端的第三固定板13以及贯穿第三固定板13设置的进光通口130；第一固定板11、第二固定板12以及第三固定板13两两相互垂直。
方棒固定支撑于支架1，弹性件2跨接于第一固定板11和第二固定板12，并将方棒向支架1抵压并形成固定。也就是说，弹性件2的一端固定于第一固定板11的远离第一固定板11和第二固定板12相连的一侧，弹性件2的另一端固定于第二固定板12的远离第二固定板12和第一固定板11相连的一侧。
进一步的，为了使方棒4的安装方便，支架1还设置了用以定位支撑方棒4的凸台部110，凸台部110包括第一定位凸台111和第二定位凸台112。
第一固定板11朝向弹性件2的一侧凸出形成至少两个间隔分布的凸台部110，每一凸台部110包括分别抵接于第二固定板12的第一定位凸台111和第二定位凸台112，第一定位凸台111与第二定位凸台112交错设置且第二定位凸台112的高度小于第一定位凸台111的高度；方棒4分别抵接于第一定位凸台111和第二定位凸台112。
光栅3固定收容于进光通口130，方棒4与进光通口130相对且沿进光通口130的光轴方向(即X轴)延伸，两个凸台部110沿光轴方向(即X轴)间隔分布；更优的，方棒沿光轴方向(X轴)朝向光栅3的正投影完全落在光栅3的范围内。
在本实施方中，方棒4包括四个分别平行于光轴方向(X轴)的侧面以及两个垂直于光轴方向(X轴)且与光栅3正对设置的端面。
方棒4的侧面包括分别平行于第一固定板11且相对间隔设置的第一面41和第二面42以及分别平行于第二固定板12且相对间隔设置的第三面43和第四面44，其中，第一面41与第三面43相邻，第二面42与第四面44相邻；第一面41靠近第一固定板11并抵接于第一定位凸台111，第三面43靠近第二固定板12并抵接于第二定位凸台112，第 二面42和第四面44靠近弹性件2。
上述结构中，凸台部110为方棒4提供了定位支撑，使得方棒4的安装更加方便，且有效地提高了方棒4的定位精度。
需要说明的是，凸台部设置的位置不限于第一固定板，凸台部也可以设置于第二固定板，即第一定位凸台和第二定位凸台由第二固定板凸出形成；当然，第一定位凸台由第一固定板凸出形成和第二定位凸台由第二固定板凸出形成也是可行的。
在本实施方式中，弹性件2包括跨接于第一固定板11和第二固定板12的弹性件主体21以及由弹性件主体21沿其长轴的一侧向第一固定板11和第二固定板12的连接处弯折延伸的弹性臂22；弹性臂22凹陷形成具有圆角的卡槽220。
弹性臂22抵压于方棒4相邻的且靠近弹性件2的两个侧面，即弹性臂22分别抵压于第二面42和第四面44；弹性臂22包括抵压于第二面42的第一臂221以及抵压于第四面44的第二臂222，第一臂221与第二臂222间隔形成卡槽220，由第二面42与第四面44共同形成的直角40卡设于卡槽220内。
第一定位凸台111和第二定位凸台112与卡槽220形成限位空间(图未标)，进一步的，限位空间朝向光栅3的正投影完全落在光栅3的范围内；方棒4固定收容于限位空间内，此时，第一臂221抵压于第二面42，由于发生弹性形变，第一臂221产生沿Y轴方向朝向第一定位凸台111的压应力，该压应力使得第一面41压向第一定位凸台111并形成固定；第二臂222抵压于第四面44，由于发生弹性形变，第二臂222产生沿Z轴方向朝向第二定位凸台112的压应力，该压应力使得第三面43压向第二定位凸台112。
上述结构中，通过弹臂22的设置，使得支架1、弹性件2和方棒4之间实现多点固定，保证了方棒4固定的可靠性，使得方棒固定装置100可适用于各种不同尺寸或不同结构形式的方棒，增强了固定装置100的适用性，使得其能够用于固定尺寸较小的微型方棒。
同时，第一臂221的圆角位置抵压于第二面42，第二臂222的圆角位置抵压于第四面44，使得弹性臂22与方棒4之间的接触面积小， 即在保证方棒4固定可靠的情况下，增大弹性件2与方棒4之间的接触面积，且减小弹性件2与方棒4之间的压强，避免弹臂22压坏方棒4，使得方棒固定装置100也能适用于微型方棒；同时，在弹性件2同时抵压于方棒4相邻的两个侧面，在安装时，避免了弹性件2产生的力矩对方棒4产生不良影响，提高方棒4安装的精度，且减小位置偏移，从而使得方棒固定装置100的可靠性高。
进一步的，本实施方式中的弹性件2一般为钣金件，钣金件的厚度较薄，为了避免弹性件主体21在弹性臂22抵压于方棒4时弯曲形变，弹性件2还设有由弹性件主体21凸出延伸的加强筋23，加强筋23与弹性臂22对应设置且分别位于弹性件主体21沿其长轴的相对两侧；通过加强筋23的设置，增加了弹性件主体21与弹性臂22对应的位置的厚度，使得设置了加强筋23的位置不易弯曲形变，从而进一步提高弹性件2的可靠性，使得方棒4的固定更加可靠，进一步有效地提高了方棒固定装置100的可靠性。
更进一步的，弹性件2的数量与凸台部110是对应设置的。比如，本实施方式中，凸台部110包括了两个，则弹性件2也包括两个，两个弹性件2相互平行且间隔设置。当然，凸台部110和弹性件2的数量是不限的，其可以根据实际使用的需要而进行具体的设置。
值得一提的是，弹性件主体21的相对两侧分别可拆卸连接于第一固定板11和第二固定板12，在本实施方式中，该可拆卸连接的方式采用螺钉紧固。
在此应该指出，第一固定板11和第二固定板12分别开设有螺纹孔10，弹性件主体21的相对两侧分别开设有贯穿其上且与螺纹孔10对应设置的通孔210，通孔210可以是光孔或者是螺纹孔，在本实施方式中，弹性件2为较薄的钣金件，因此通孔210一般设为光孔。
方棒固定装置100还包括螺钉5，螺钉5穿过通孔210与螺纹孔10形成螺纹固定并使弹性件主体21固定于支架1。
当然，弹性件与支架的固定方式不限于螺纹紧固的形式，采用其他可拆卸连接的固定方式对弹性件和支架进行固定也是可以的，比如，弹性件可拆卸卡扣于支架，或者弹性件上设置凸柱，固定板板上设置孔进 行配合也是可行的。
与相关技术相比，本实用新型的方棒固定装置包括支架以及可拆卸连接于支架的弹性件，支架包括相互垂直连接的第一固定板和第二固定板，弹性件跨接于第一固定板和第二固定板；本实用新型的光学设备包括本实用新型的方棒固定装置以及方棒，方棒支撑于第一固定板和第二固定板，弹性件将方棒抵压于第一固定板和第二固定板并形成固定，固定装置的在光学设备的应用，使得在安装方棒时，避免了方棒受到弹性件产生的力矩影响，使得方棒安装的精度高且位置偏移小，从而使得方棒固定装置的可靠性高；同时，通过增大接触面积的方式减小弹性件与方棒之间的压强，避免坏方棒，使得方棒固定装置也能适用于微型方棒。
以上所述的仅是本实用新型的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本实用新型创造构思的前提下，还可以做出改进，但这些均属于本实用新型的保护范围。
