优选地，镜框连接件的连接凸块至少有一个弧形抵触端面，该弧形抵触端面与定位槽孔的中心为偏心结构，在所述镜框连接件受力时，镜框连接件会沿着第一活动槽活动，该状态下所述弧形抵触端面与所述第一活动槽端面是线性接触，实现在失去外力作用时复位功能。
优选地，所述的弧形抵触端面设置有两个，其中所述第一活动槽底面为180度平面，镜框连接件的连接凸块活动在述第一活动槽内，通过设置弧形抵触端面该镜框连接件双向自动复位。

实施例
如图1至图14所示，本实用新型公开了应用于眼镜的新型眼镜脚组件，包括弹簧机芯5、用于连接镜框的镜框连接件4以及用于连接镜脚的镜脚连接件1，
镜框连接件4连接镜框的作用即桩头，本方案的桩头内不需要设置弹簧，镜脚连接件1作为连接镜脚以让其实现旋转的需求，弹簧机芯5设于镜脚连接件4上，镜框连接件1与镜脚连 接件4之间安装有中枢块2，镜框连接件1、中枢块2与镜脚连接件4依次相互抵靠设置，三者且通过弹簧机芯5连接成一体，中枢块2具有活动槽口，所述镜框连接件相可沿着中枢块的活动槽口多方向旋转，所述的弹簧机芯包括具有弹性功能的伸缩件8，伸缩件8一般采用弹簧，形变的镜框连接件通过伸缩件可复位至原来状态，其中图1为本产品的初始状态。
具体地，所述的镜脚连接件4开有通腔，弹簧机芯还包括有滑杆，该滑杆设于通腔中并伸出形成有连接端头3，中枢块2具有第一活动槽A和第二活动槽B，第一活动槽A和第二活动槽B相交形成有相通区2-2，所述的镜框连接件1具有连接凸块1-7，滑杆的连接端头3从中枢块的第二活动槽B伸到相通区2-2，镜框连接件的连接凸块1-7从中枢块的第一活动槽A伸到相通区2-2与所述连接端头相连接，形成旋转支点，使镜框连接件1、中枢块2与镜脚连接件4三个部件组装成一个整体。伸缩件8一般是一端安装在滑杆的末端12上，另一端抵触在镜脚连接件4壳体13外，如果滑杆向上拉会压缩弹簧，根据弹簧的特性，产生一个回复的力。
第一活动槽A的作用是让镜框连接件1在通过其设置的连接凸块1-7实现在力的作用下发生旋转，即图1中所示的H和G方向，可参考图11-14的示意；第二活动槽B的作用是镜框连接件1和中枢块为一体，沿着E和F方向旋转，参考图7-10，实现了单个弹簧机芯即可多方向旋转的效果，设计比较独特，其依据的是以连接凸块1-7与连接端头3的配合作为支点。
其中，所述的连接端头具有弧形槽口3-1以及定位凸起，弧形槽口3-1以及定位凸起构成的钩状连接端头，连接凸块开有定位槽孔1-4，定位槽孔内加工有弧形凸面，连接端头与连接凸块的定位槽孔配合时，所述的弧形槽口3-1贴合在弧形凸面上，使用该结构目的是保证旋转时，利用圆弧的设计以及其特点，实现旋转的顺畅以及运行的可靠性。
镜框连接件1的连接凸块1-7至少有一个弧形抵触端面1-6，该弧形抵触端面1-6与定位槽孔的中心为偏心结构，在所述镜框连接件受力时，镜框连接件会沿着第一活动槽活动，该状态下所述弧形抵触端面与所述第一活动槽端面是线性接触，实现在失去外力作用时复位功能，偏心结构的特性是在倾斜一方时，结合本方案的弹簧机芯其是可以快速拉回原来的状态，而且不需要受力。
进一步的，所述的弧形抵触端面1-6设置有两个，其中所述第一活动槽底面2-3为180度平面，镜框连接件的连接凸块活动在述第一活动槽内，通过设置弧形抵触端面该镜框连接件双向自动复位，实现两个方向的旋转。
镜脚连接件具有适配平台7，该适配平台7与所述的中枢块下端面抵靠，中枢块的下 端面至少有一个圆弧过渡端面C和直角过渡端面D。所述的适配平台具有与圆弧过渡端面相接触的侧挡台6，该侧挡台呈斜状设置。其中，直角过渡端面和圆弧过渡端面处于中枢块的下端面两对面。由于运动在第二活动槽B方向，但是眼镜脚一般在收纳时需要折叠，故本方案设计了直角过渡端面D，其可以在受力作用下，不会发生自动复位，具体可以参考图9-图10，而圆弧过渡端面C的目的是让其能快速自动复位，再利用增设呈斜状的侧挡台，进一步的实现快速回位。均可沿着第一活动槽和第二活动槽的两边旋转90°。
中枢块的第一活动槽和第二活动槽呈90度形式设置。该方案可以实现四个方向90°的旋转。
所述的镜框连接件具有上滑行平台1-2，该上滑行平台1-2具有两个呈弧状的侧壁1-3，对应的中枢块具有弧形上端面2-1，侧壁贴合在弧形上端面相互抵触。通过该方案进一步保证了镜框连接件运行的可靠性和顺畅。
本方案的工作原理为：
1、镜框连接件1在中枢块部件的第一活动槽A以连接凸块1-7和连接端头3的连接处的支点，沿着槽的两边转动90°，当镜框连接件1尾部没有作用力时部件在弹簧8的拉伸力下，由于镜框连接件1部件的定位槽孔1-4的孔中心与弧形抵触端面1-6部件的两边圆弧是偏心的，在弹簧机芯的作用力下使其自动弹回原来位置。
2、当作用G方向时，会向前压到90°时，由于中枢块的D处为直角即不设置成圆弧的即可，使其可以定位在90°，该状态一般是在收纳镜脚时。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。
