所述安装槽31内设有弹性连接件5，所述弹性连接件5采用弹性金属件一体成型，其包括支撑环52、弹性片51、限位环53，所述弹性片51设有2个，并对称设置，所述限位环53设置在支撑环52下端外圈。
其中，所述弹性片51包括有向内凸的卡接部511以及卡接部511上下两端向外延伸的导向部512，具体的，所述卡接部511与导向部512形成开口朝外的“V”型结构。
所述安装槽31内壁底部形成有环形限位槽32，所述安装槽31的内侧壁上形成有与弹性片51相对应的借位槽33，所述弹性连接件5通过支撑环52固定嵌设在环形限位槽32内，安装方便，所述弹性片51与借位槽33对应以保证有足够的空间进行变形动作，同时限位环53与安装槽31的下端限位配合，同时接头底座3通过螺栓固定安装在机身1上时，能与机身1共同夹紧限位环53，以保证弹性连接件5的固定安装。
所述环形安装凸台41外设有卡台42，当环形安装凸台41插入到安装槽31内时，卡台42与弹性连接件5的弹性片51限位配合，使得接头4牢固地安装于接头底座3上。
所述接头底座3与接头4通过弹性片51与卡台42的配合结构实现固定连接，其在拆卸过程中，能够通过弹性片51的导向部512，带来一定的引导作用，带动弹性片51变形，拆卸操作更加轻松方便，同时通过弹性片51的卡接部511与卡台511形成限位卡接，通过弹性片51本身的弹性特性，使得其能够保持牢固的固定支撑，确保不会出现在使用过程中的意外脱落问题，进而达到头部2与机身1之间理想的连接状态。
进一步的，所述卡台42上下端面倾斜设置形成导向斜面结构，与弹性片51 的“V”型结构配合，拆卸更加简单。
所述环形安装凸台41外还形成有与安装槽31适配的限位凸环45，且所述卡台42与限位凸环45之间形成与弹性片51相适配的卡槽46，设置限位凸环45，使得接头4与接头底座3连接更加牢固。
当然，也可以如图12所示不设置限位凸环，这样在剃须过程中，浮动效果更好更加灵活。
另外，所述接头4上端形成有球形凸台43，所述头部2下端固定设置有枢转连接件6，所述枢转连接件6中心对应形成有球面安装槽61，所述接头4向上至下穿过球面安装槽61设置，所述球形凸台43与球面安装槽61轴向限位并形成球面配合，通过球面配合，能够实现较好的浮动效果，更好地适应人体轮廓，相较于常规的十字形万向浮动结构，结构更加灵活简单，而且零件更好，易于实现，成本低。
进一步的，在所述球形凸台43外表面向外凸出有两个中心对称设置的限位轴44，所述球面安装槽61侧壁对应形成有限位槽62，所述限位轴44卡入限位槽62，保证其不会出现轴向转动，保证良好的剃须效果。
另外，所述个人护理装置不局限于剃须刀，在实际应用中，上述个人护理装置还可以是剃毛器、按摩器等。
