同时，限位部42与连接部43垂直布设，简化了加工工艺，使得模具简单，装配方便的同时，也节省了成本。
具体的，连接部43内置有旋转槽43-1，与此相对应的，尼龙旋转件45上固设有与旋转槽43-1相适配的卡扣闷头43-2，卡扣闷头43-2套接于旋转槽43-1内。
限位部42外侧沿其长度方向布设有限位凸条42-1，相对应的，第一轴承套管2-2内侧形成有与限位凸条42-1相适配的凹槽2-3；通过限位凸条42-1与凹槽2-3之间的相互卡接配合，使得轴承定位座40与子页片5的第二轴承套管3-3定位，这样子页片5在旋转过程中，进而带动轴承定位座40在轴芯30上旋转。
外壳44的上端面与尼龙旋转件45的上端面在同一平面；本实用新型设置有外壳44，外壳44卡接于连接部与尼龙旋转件上，而且，在合页装配过程中，外壳位于第一轴承套管与第二轴承套管之间，减少了缝隙产生，同时，外壳采用不锈钢的保护套，颜色可电镀同合页，更美观。
导向部41的端部呈圆弧过渡结构41-1；导向部41上形成有导向缺口41-2，该导向缺口 41-2与限位凸条42-1位置相对应；且圆弧过渡结构41-1形成有导向面，这样方便第二轴承套管3-3插接于轴承定位座40上，提高两者之间的装配效率，同时，导向部41上形成有导向缺口41-2，该导向缺口41-2与限位凸条42-1位置相对应；方便了限位凸条42-1能快速准确的插入导向缺口41-2。
第二轴承套管3-3沿其长度方向形成有连接槽3-5；尼龙套32装配于连接槽3-5内，所述连接部43顶部周向形成有呈V形结构的内凹槽46，与此相对应的，尼龙旋转件45底部周向形成有呈V形结构的凸起块47，尼龙旋转件45装配于连接部43时，凸起块47贴合安装于内凹槽46上；本实用新型通过设置呈V形结构内凹槽和凸起块相互贴合连接，使得连接部与尼龙旋转件之间的旋转受力面改变，更耐磨和抗压，其受力面主要集中在V形结构的斜面上，受力面积越大，压力越小，整体的装配稳定性就越高。
本实用新型的尼龙旋转件通过按压的方式镶嵌于连接部的旋转槽43-1内，通过自身的旋转起到了轴承的作用；其材质为尼龙66，机械强度和硬度很高，刚性很大；并添加了聚四氟乙烯，它的摩擦系数极低，所以可作润滑作用。
第一轴承套管2-2的端部装配有螺栓2-5，其中，螺栓2-5呈T型结构，螺栓2-5的一端伸入第一轴承套管2-2内，另一端抵靠于第一轴承套管2-2上；螺栓2-5对于轴芯30起到保护限位作用。
