可以理解的，上述的QBH接头200与第一筒体110紧配合，限制QBH接头200相对第一筒体110移动错位，还设置止转结构120固定QBH接头200，止转结构120包括第一销轴121，第一销轴121固定于第一筒体110上，第一销轴121沿垂直于第一筒体110轴线的方向布置，第一销轴121的一端与QBH接头200上的第一凹槽210对正，当QBH接头200插入承插容纳腔111内时，第一销轴121的第一端位于第一凹槽210内，第一销轴121的第一端沿第一凹槽210轴向滑动，至第一销轴121与第一凹槽210的槽壁上端抵接，限制QBH接头200相对第一筒体110旋转，第一销轴121的第二端与第二凹槽310对正，当第一筒体110插入QD光纤连接块300内时，第一销轴121的第二端沿第二凹槽310轴向滑动，至第一销轴121的第二端与第二凹槽310的槽壁下端抵接，限制QD光纤连接块300转动，第一销轴121能够同时连接QBH接头200和QD光纤连接块300，并限制QBH接头200和QD光纤连接块300转动，激光输出头转接装置100的结构简单紧凑，体积小。作为变形的，也可以在第一筒体110上设置两根销轴，一根销轴连接QBH接头200和第一筒体110，另一根销轴连接QD光纤连接块300和第一筒体110，也能够实现限制QBH接头200和QD光纤连接块300转动的目的。
参见图1、图2、图3和图4所示，图3为本申请实施例提供的转接装置的侧视图，图4为图3中A-A剖视图。
在一些实施方式中，止转结构120还包括第二筒体122和第二销轴123，第二筒体122为中空的圆筒结构，第二筒体122套设于插接段112上，第二筒体122的内壁与插接段112的外壁贴合，第二筒体122与插接段112同轴设置，第二筒体122与插接段112转动连接；第二销轴123沿第二筒体122的径向延伸，插接段112上设有周向布置的通孔114，第二销轴123位于通孔114内，第二销轴123具有第一端和第二端，第二销轴123的第一端与第二筒体122固定连接，第二销轴123的第二端穿过通孔114，延伸至承插容纳腔111内，第二筒体122转动，带动第二销轴123在通孔114内沿周向移动，第二销轴123的第二端从通孔114的一侧移动至另一侧，当QBH接头200插入承插容纳腔111内，第二销轴123的第二端位于QBH接头200上的第三凹槽220内，转动第二筒体122，第二销轴123的第二端可与第三凹槽220的侧壁抵接配合，以限制QBH接头200沿轴向移动。
上述第二销轴123和通孔114的数量和设置的位置与QBH接头200上的第三凹槽220的数量和位置对应，设置三根第二销轴123，对应的第一筒体110的侧壁上开设有三个通孔114，三根第二销轴123沿第二筒体122的圆周等距离间隔设置，三个通孔114沿第一筒体110的圆周等距离间隔设置，且通孔114由两第一槽壁和两第二槽壁围合而成，第一槽壁沿第一筒体的圆周延伸，第一槽壁呈弧形，第一槽壁的中部向止推段一侧凹陷，第二槽壁呈圆弧形连接两第一槽壁的端部，第二销轴123在通孔114内移动顺畅，便于操作。
可以理解的，通过上述的第一销轴121限制QBH接头200绕轴线转动，第二销轴123限制QBH接头200沿轴线上下移动，将QBH接头200锁紧固定于激光输出头转接装置100内部，通过第二筒体122转动带动第二销轴123移动，合理利用插接段112与QD光纤连接块300内壁之间的间隙，结构紧凑，设计巧妙。
在上述实施方式的基础上，参见图4所示，第二筒体122靠近止推段113的一端与止推段113之间间隔一定距离，第二筒体122背离止推段113一端的边缘设有多个缺口124，多个缺口124沿第二筒体122的边缘周向间隔设置，对应的，插接段112上设有多个凸起125，多个凸起125沿插接段112的外壁周向间隔设置，多个凸起125与第二筒体122背离止推段113一端的边缘贴合，转动第二筒体122，第二销轴123的第二端从通孔114的一侧移动至另一侧，凸起125移进或移出缺口124。
可以理解的，上述的第二筒体122可以与插接段112外壁紧配合，限制第二筒体122转动，但考虑到第二筒体122与插接段112外壁之间的摩擦力较大，不利于操作，因此，通过在第二筒体122的边缘设置多个缺口，当第二筒体122转动到位后，第二销轴123与第三凹槽220的侧壁抵接时，凸起125位于缺口124内，第二筒体122的缺口124与凸起125贴合，限制第二筒体122转动，提高了止转结构120与QBH接头200配合的结构稳固性。
在上述实施方式的基础上，参见图4所示，第二筒体122背离缺口124的一端与止推段113之间设置有第一弹性件126，第一弹性件126产生的弹性恢复力沿第二筒体122轴向延伸，以使得第二筒体122的边缘与凸起125贴合。
可以理解的，参见图4和图5所示，上述的第一弹性件126为弹簧，弹簧套设在插接段112上，弹簧的一端与止推段113抵接，弹簧的另一端与第二筒体122靠近止推段113的一端抵接，第二筒体122靠近止推段113的一端与插接段112的外壁之间形成一弹簧槽128，弹簧的另一端位于弹簧槽128内，防止弹簧滑出，弹簧处于弹性压缩状态下，随着第二筒体122转动，弹簧的弹性恢复力作用于第二筒体122上，将第二筒体122的边缘抵靠凸起125，当凸起125位于缺口124内，限制第二筒体122转动，以提高转接装置整体结构的稳固性。
在上述实施方式的基础上，参见图4所示，止推段113的外壁设有限位槽127，限位槽127向止推段113的轴向凹陷，限位槽127用于与QD光纤连接块300上的限位珠320抵接，以限制QD光纤连接块300轴向移动。
参见图7和图9所示，图9为图7中E处的局部放大图。
上述的限位槽127由第一侧壁1270、第二侧壁1271和底壁1272围合呈的一侧开口的槽结构，开口向QD光纤连接块300一侧，底壁1272连接第一侧壁1270和第二侧壁1271，第一侧壁1270背离插接段112一侧，第一侧壁1270与底壁1272垂直，第二侧壁1271靠近插接段112一侧，第二侧壁1271倾斜设置，第二侧壁1271向插接段112的方向倾斜，限位槽127的开口的截面形状呈喇叭状，大于限位珠320位于QD光纤连接块300外的部分尺寸，以方便限位珠320进入限位槽127内。
参见图10和图11所示，图10为本申请实施例提供的激光输出头组件的结构示意图，图11为图10中F-F剖视图。
本申请实施方式中还提供一种激光器输出组件，包括上述任一项的激光输出头转接装置100、QD光纤连接块300和QBH接头200，其中，QD光纤连接块300包含有套筒结构330，套筒结构330内设有沿轴向贯通的第一腔体340，套筒结构330可套设于与第一筒体110上，通过止转结构120与第一筒体110连接，第一腔体340与承插容纳腔111连通，QBH接头200可插入承插容纳腔111内，进入第一腔体340内，通过止转结构120与第一筒体110连接。
参见图12所示，图12为本申请实施例提供的QD光纤连接块的结构示意图。
上述的套筒结构330包括第一套筒331、锁紧套筒333、第三套筒335和锁紧螺钉338，第一套筒331设有第一腔体340，第一套筒331的外表面设有周向布置的法兰连接盘332，第一套筒331的靠近激光输出头转接装置100的一端边缘处设有第二凹槽310，第二凹槽310可以与第一销轴121的第二端抵接，第一凹槽210、第二凹槽310和第一销轴121沿轴线布置，且第一凹槽210、第二凹槽310和第一销轴121位于同一直线上；锁紧套筒333套设于第一套筒331上，锁紧套筒333的内壁与第一套筒331的外壁之间形成间隙334，间隙334内设有限位珠320，限位珠320部分延伸出第一套筒331，锁紧套筒333背离激光输出头转接装置100的一端与法兰连接盘332之间设有第二弹性件337，锁紧套筒333可沿轴线方向移动，锁紧套筒333向下移动，限位珠320沿径向向外松动，将第一销轴121的第二端与第二凹槽310对中，转接装置100插入QD第一套筒331内，至第一销轴121与第二凹槽310抵接，松开锁紧套筒333，限位珠320受锁紧套筒333的作用向靠近轴线的方向径向移动，嵌入限位槽127内，限制转接装置100径向移动，向下按压锁紧套筒333，限位珠320向背离轴线的方向径向移动，限位珠320与限位槽127脱落，沿轴向拔出转接装置100；第三套筒335套设于第一套筒331上，第一套筒331上设有刻度尺336，刻度尺336的一端与法兰连接盘332的一侧连接，另一端向背离法兰连接盘332的一侧延伸，第三套筒335上设有与刻度尺336配合的窗口，第三套筒335沿轴向移动；锁紧螺钉338，沿径向布置，锁紧螺钉338的一端穿过第三套筒335与第一套筒331抵接，以固定第三套筒335。
可以理解的，切割应用过程中，更换激光输出头后，需要对激光切割头的焦距进行调节，将激光聚焦到指定位置，从而达到更好的加工质量，一般通过调节第三套筒335的上下位置，来调节激光器输出的焦点位置，本申请实施方式中设置刻度尺336，当QD接头与QD光纤连接块300连接时，调焦后，记录下刻度尺336上的刻度为第一刻度，当QBH接头通过转接装置100与QD光纤连接块300连接，调焦后，记录下刻度尺336上的刻度为第二刻度，后续再更换激光输出头后，只需要根据激光输出头的类型，将第三套筒335调节到第一刻度或第二刻度即可，操作简单，调试效率高，提高了激光加工效率。
