参见图6-7所示，转子7位于固定轴17远离过渡驱动盘1圆心的一侧。
凸轮槽6开设于凸轮盘4的下部，或沿竖直方向贯穿凸轮盘4。凸轮槽6用于在相对过渡驱动盘1转动时，通过转子7驱动第一夹手3在伸出位置和缩回位置之间切换。当凸轮槽6未贯穿凸轮盘4时，通过凸轮槽6的顶部抵触转子7的顶部，防止转子7在凸轮槽6中运动时发生竖直方向的位移；当凸轮槽6贯穿凸轮盘4时，通过在凸轮槽6中设置限位件抵触转子7的顶部，防止转子7在凸轮槽6中运动时发生竖直方向的位移。
在本实施例中，凸轮槽6沿自身凸轮曲线的方向曲线靠近或曲线远离第一轴12的轴心线，凸轮槽6沿背离第一轴12的方向弧形外凸。多个凸轮槽6形状相同，用于在凸轮盘4相对过渡驱动盘1转动时，通过多个转子7一一对应的驱动多个第一夹手3同步伸出或同步缩回，以在伸出位置和缩回位置之间同步切换。多个第一夹手3的伸出速度和缩回速度完全相同，伸出距离和缩回距离也完全相同。参见图2-3所示，转子7位于凸轮槽6远离第一轴12的一端时，第一夹手3向外伸至最远处，转子7位于凸轮槽6靠近第一轴12的一端时，第一夹手3向内缩至最里处。
上述一种用于瓶子传送的保护装置还包括同轴环设于过渡驱动盘1外侧周部的且用于配合第一夹手3抵接瓶子瓶口的圆弧形挡圈11。通过设置该圆弧形挡圈11，不仅用于配合第一夹手3承载抵接并传送瓶子，还用于在第一夹手3缩回后，使瓶子从圆弧形挡圈11与过渡驱动盘1之间的间隙中向下掉落。
一种用于瓶子传送的保护方法，包括以下步骤：
(1)将上游的吹瓶机构8输出的瓶子通过过渡驱动盘1送入下游的灌装机构10中，在过渡驱动盘1上设置可伸缩的用于夹持瓶子的第一夹手3；第一夹手3伸出时，用于配合上游的吹瓶机构8出瓶，还用于配合下游的灌装机构10进瓶；参见图2所示，第一驱动盘2沿顺时针方向转动，用于通过机械手9取出吹瓶机构8中吹制成型的瓶子，过渡驱动盘1逆时针转动，用于通过第一夹手3接收机械手9上的瓶子，第二驱动盘顺时针转动，用于通过第二夹手接收第一夹手3上的瓶子；此时动力机构5未启动，凸轮盘4与过渡驱动盘1同步转动；
(2)当吹瓶机构8和灌装机构10中的一个或两个出现异常时，动力机构5驱动凸轮盘4相对过渡驱动盘1逆时针转动，使转子7进入凸轮槽6靠近第一轴12的一端，使第一夹手3直线内缩或转动内缩，第一夹手3与上游的机械手9之间间隔排列，并使第一夹手3与下游的第二夹手之间间隔排列；使过渡驱动盘1同时与上游的第一驱动盘2和下游的第二驱动盘之间解除联动，避免了紧急制动时由于上下游不同步造成的撞击问题；
(3)当需要单独调节吹瓶机构8或灌装机构10时，动力机构5驱动凸轮盘4相对过渡驱动盘1逆时针转动，使转子7进入凸轮槽6靠近第一轴12的一端，使第一夹手3直线内缩或转动内缩，第一夹手3与上游的机械手9之间间隔排列，并使第一夹手3与下游的第二夹手之间间隔排列；使过渡驱动盘1同时与上游的第一驱动盘2和下游的第二驱动盘之间解除联动，避免了调节时由于上下游不同步造成的撞击问题，实现了吹瓶机构8和灌装机构10之间联动的临时解除。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并加以实施，并不能以此限制本发明的保护范围，凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
