上述保护机构包括滑动安装在壳体2上的两个保护盖10，其中一个保护盖10靠近操作手柄5，保护盖10均包括固定连接的第一段和第二段13，第一段和第二段13相互平行，且第一段位于第二段13的外侧，爪扣9位于第二段13的移动路径上。操作手柄5上滑过程中，靠近爪扣9的第二段13会被带动一起上滑，从而使靠近操作手柄5的保护盖10整体上滑，保护盖10的第一段12位于第二段13的外侧，从而靠近操作手柄5的保护盖12的第一段可以上滑至另一个保护盖10的第一段12的下方，保护盖10的第一段12的移动行程即为操作手柄5的移动行程。
实施例2
如图4、图5、图8所示，一种卷动窗帘安全防护操作结构，本实施例和实施例1的区别在于操作壳6上设有安装操作按钮的安装槽，操作壳6上设有位于安装槽中间的挡条21，挡条21的设置方向和壳体2的长度方向相同，挡条21的宽度小于等于隔离墙17的端面的宽度，操作按钮和挡条21之间设有若干弹簧18，操作按钮的上下两端分别设有向对应侧延伸出去的卡扣19。操作按钮整体都可以被按下，按压接触面大，按压更加的方便，弹簧18可以让操作按钮按压后自动回弹。
上述操作按钮包括上行按钮7和下行按钮8，上行按钮7正对上行腔3设有向壳体2垂直延伸的拉珠绳卡接部，下行按钮8正对下行腔4设有向壳体2垂直延伸的拉珠绳卡接部，上行按钮7和下行按钮8均可垂直于壳体2方向来回移动。
上述拉珠绳卡接部为爪扣9，当操作按钮按下时，爪扣9会嵌入拉珠绳1的两个拉珠之间，滑动操作手柄5上行或下行可以带动拉珠绳1上行或下行。
上述拉珠绳卡接部也可以为多个设置在同一直线上的爪扣9，每个爪扣9对应拉珠绳1上两个相邻拉珠之间的绳子。多个爪扣9的设置可以使操作按钮和拉珠绳1的接触卡点增多，从而能够方便拉动重量比较大的窗帘。
实施例3
本实施例和实施例1或实施例2的区别在于开口侧的壳体2上设有将部分开口遮住的保护机构，保护机构和操作手柄5一起将开口完全遮住，不仅防止异物进入壳体2卡住拉珠，保护拉珠的操作安全；还可以防止拉珠从壳体2内外露被儿童拿去玩耍，造成不必要的安全隐患。上述保护机构包括滑动安装在壳体2上的两个保护盖10，其中一个保护盖10靠近操作手柄5，保护盖10均包括固定连接的第一段和第二段13，第一段和第二段13相互平行，且第一段位于第二段13的外侧，爪扣9位于第二段13的移动路径上。操作手柄5上滑过程中，靠近爪扣9的第二段13会被带动一起上滑，从而使靠近操作手柄5的保护盖10整体上滑，保护盖10的第一段12位于第二段13的外侧，从而靠近操作手柄5的保护盖12的第一段可以上滑至另一个保护盖10的第一段12的下方，保护盖10的第一段12的移动行程即为操作手柄5的移动行程。
本实用新型的实施1到实施例3中的任意一种壳体2都可以为如图9所示的第一种壳体或第二种壳体，第一种壳体的壳体和上行腔3之间、上行腔3和下行腔4之间、下行腔4和壳体2之间均设有空腔20。第二种壳体的上行腔和下行腔之间的隔离墙17为空心，可以节省壳体的材料，同时不影响壳体的体积，和第一种壳体比起来可以使壳体的体积更小。
上述第一种壳体或第二中壳体的表面还可以设有凹凸的波浪结构22，均匀的波浪结构可以增加壳体表面的摩擦力，增加握持的力度，且波浪结构22还可以在壳体碰撞的时候提供一定的保护，减轻壳体表面的碰撞接触，减轻壳体表面的碰撞擦伤。
文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
