较佳地，所述锁卡凹槽之后槽壁向前上方倾斜延伸出厚度尺寸呈相同、递增或递减布置的凸起舌头。
较佳地，所述锁卡凹槽之后槽壁表面及下槽壁表面均为平面且两者之间夹角为锐角，所述锁卡凹槽的左槽壁表面和右槽壁表面由所述手柄的下至上方呈逐渐靠近彼此方向的倾斜布置。
为实现上述的目的，本申请的手柄具有匹配所述接纳腔的插接头，所述插接头开设有锁卡凹槽，所述锁卡凹槽的槽口形成于所述插接头的后表面及上表面，所述锁卡凹槽的前槽壁表面由所述手柄的下至上的方向向所述手柄的后上方倾斜，所述锁卡凹槽的前槽壁表面与所述倾斜面面面抵接，所述倾斜面与所述下表面之间的交汇处位于所述锁卡凹槽的前槽壁表面与下槽壁表面之间的空间。
与现有技术相比，由于构件壳体的前侧向上延伸出的弹性卡接臂，弹性卡接臂的自由端向构件壳体的后方弯曲并位于接纳腔内，弹性卡接臂的自由端具有上表面、下表面及连接于上表面和下表面之间并位于后方的倾斜面，倾斜面由构件壳体的下至上的方向向构件壳体的前上方倾斜，故在手柄的插接头插入接纳腔的过程中，由插接头顶推弹性卡接臂的自由端做靠近构件壳体的前方弹性变形，从而使得插接头顺畅地越过倾斜面与下表面的交汇处再与倾斜面进行 面面抵接，因而使插接头可靠地夹持于倾斜面与接纳腔对应的腔壁之间，再结合自由端的倾斜面与插接头面面抵接，故借助由构件壳体单侧延伸出的一个弹性卡接臂便能实现互联构件与手柄之间的扣合连接，以在确保互联构件与手柄之间可靠扣合的条件下实现单点扣合，以简化结构。

具体实施方式
为了详细说明本申请的技术内容、构造特征，以下结合实施方式并配合附图作进一步说明。
如图1及图2所示，本申请的互联构件10与手柄20对插配合，以便于互联构件10与手柄20之间的装拆连接；为便于互联构件10与手柄20之间的拆卸，故在手柄20设有释锁操作件30，但不限于此。
结合图3及图4，互联构件10包括构件壳体11、由构件壳体11的左右两侧分别向上延伸出的枢摆支撑臂12及由构件壳体11的前侧向上延伸出的弹性卡接臂13。构件壳体11的内部具有接纳腔111，接纳腔111贯穿构件壳体11的上端面112及下端面113，以便于手柄20从下端面113插入接纳腔111内；弹性卡接臂13的自由端131向构件壳体1的后方弯曲并位于接纳腔111内，弹性卡接臂13的自由端131具有上表面1311、下表面1312及连接于上表面1311和 下表面1312之间并位于后方的倾斜面1313，倾斜面1313由构件壳体11的下至上的方向向构件壳体11的前上方倾斜，一方面便于下面描述到的手柄20之插接头21在插入接纳腔111的过程中顺畅地越过倾斜面1313与下表面1312的交汇处1314，再与倾斜面1313面面抵接；另一方面借助倾斜面1313与插接头21的面面抵接，使得倾斜面1313在插接头21的拔出方向增加对插接头21的阻挡力，有效地防止插接头21与弹性卡接臂13的自由端131之间的意外释卡。具体地，倾斜面1313与下表面1312之间的交汇处1314及倾斜面1313与上表面1311之间的交汇处1315为弧形过渡，故在插接头21插入接纳腔111的过程中，使得插接头21更顺畅地越过倾斜面1313与下表面1312之间的交汇处1314，再与倾斜面1313面面抵接，借助倾斜面1313与上表面1311之间的交汇处1315，防止上表面1311给倾斜面1313与插接头21之间的面面抵接带来干扰，进一步确保倾斜面1313与插接头21之间面面抵接的可靠性。举例而言，上表面1311及下表面1312各为外凸的弧形表面，上表面1311的弧径大于下表面1312的弧径，以使得自由端131为弧形钩，但不以此为限。可理解的是，根据实际需要，倾斜面1313与下表面1312之间的交汇处1314或倾斜面1313与上表面1311之间的交汇处1315为弧形过渡，故不以此为限。更具体地，如下：
如图1及图4所示，构件壳体11分别向上延伸出从构件壳体11之左侧包围接纳腔111的左围臂114及从构件壳体11之右侧包围接纳腔111的右围臂115，弹性卡接臂13从构件壳体11的前侧包围接纳腔111并呈间隔开地位于左围臂114及右围臂115之间，以使得接纳腔111形成扁窄的腔体，从而使得插接头21与接纳腔111之间的配合更好；具体地，构件壳体11之左侧的枢摆支撑臂12呈间隔开地位于左围臂114的左侧，构件壳体11之右侧的枢摆支撑臂12呈间隔开地位于右围臂115的右侧，这样设计能防止装配于枢摆支撑臂12上的刀头在枢摆过程中分别与左围臂114和右围臂115造成干扰，因而确保刀头枢摆的可靠性，但不限于此。
如图1至图2，以及图5及图6所示，手柄20具有匹配接纳腔111的插接头21，插接头21开设有锁卡凹槽211，锁卡凹槽211的槽口211a形成于插接头 21的前表面21a及上表面21b，锁卡凹槽211的后槽壁表面211b由手柄20的下至上的方向向手柄20的前上方倾斜，以使得后槽壁表面211b与倾斜面1313的倾斜匹配，从而使得锁卡凹槽211的后槽壁表面211b与倾斜面1313相抵接；倾斜面1313与下表面1312之间的交汇处1314位于锁卡凹槽211的后槽壁表面211b与下槽壁表面211c之间的空间2111，状态见图3所示。具体地，锁卡凹槽211之后槽壁表面211b及下槽壁表面211c均为平面且两者之间夹角为锐角，锁卡凹槽211的左槽壁表面211e和右槽壁表面211f由手柄20的下至上方呈逐渐靠近彼此方向的倾斜布置，使得弹性卡接臂13的自由端131在插接头21插入接纳腔111的过程中更顺畅地卡于锁卡凹槽211内，借助左槽壁表面211e及右槽壁表面211f，并有效地防止位于锁卡凹槽211内的弹性卡接臂13的自由端131左右晃动。为使得插接头21更容易顺畅地越过倾斜面1313与下表面1312之间的交汇处1314，锁卡凹槽211之后槽壁向前上方倾斜延伸出厚度尺寸呈相同、递增或递减布置的凸起舌头211d，但不限于此。
如图2及图3所示，释锁操作件30包含滑设于手柄20的按压头31及与按压头31连接的顶推杆32，顶推杆32穿置于插接头21内，顶推杆32还伸至锁卡凹槽211并位于弹性卡接臂13的自由端131正下方，以在使用者对按压头31进行按压操作时，使顶推杆32跟随按压头31相对手柄20滑移，从而使滑移的顶推杆32顶推弹性卡接臂13的自由端131产生弹性变形，以使得弹性卡接臂13的自由端131脱离与插接头21的锁卡凹槽211的锁合，从而实现弹性卡接臂13的自由端131与插接头21之锁卡凹槽211相释锁的目的。具体地，按压头31及顶推杆32沿手柄20的上下方向滑动布置，故当使按压头31沿图7c中按压头31旁边的箭头所指方向滑移时，使得顶推杆32跟随按压头31一起滑移，从而由滑移的顶推杆32顶推弹性卡接臂13之自由端131沿图7c中的箭头C所指方向弹性变形，进而使得弹性卡接臂13之自由端131脱离与插接头21的锁卡凹槽211的锁合，因而允许互联构件40与手柄20之间的拆卸，但不以此为限。
结合图7a至图7c，对手柄20与互联构件10的扣合过程进行说明：如图7a 所示，使手柄20沿插接头21旁边的箭头所指方向插入互联构件10的接纳腔111内，直到插接头21之凸起舌头211d的端部与倾斜面1313和下表面1312之间的交汇处1314相抵接为止；当插接头21之凸起舌头211d的端部与倾斜面1313和下表面1312之间的交汇处1314相抵接时，此时保持原来的方向使插接头21继续插入接纳腔111，使得插接头21之凸起舌头211d的端部顶推弹性卡接臂13的自由端131沿图7b中箭头C所指方向产生弹性变形，状态见图7b所示，从而使得倾斜面1313和下表面1312之间的交汇处1314避开对插接头21之凸起舌头211d的端部阻挡，以允许对插接头21之凸起舌头211d的端部越过倾斜面1313和下表面1312之间的交汇处1314，而倾斜面1313和下表面1312之间的交汇处1314则从锁卡凹槽211的槽口211a进入锁卡凹槽211内，并在弹性卡接臂13的弹性力作用下，使得倾斜面1313和下表面1312之间的交汇处1314在插接头21继续插入接纳腔111的过程中沿着锁卡凹槽211的后槽壁表面211b滑移，直到弹性卡接臂13的自由端131的倾斜面1313与后槽壁表面211b面面抵接为止，状态见图7c所示。
与现有技术相比，由于构件壳体11的前侧向上延伸出的弹性卡接臂13，弹性卡接臂13的自由端131向构件壳体11的后方弯曲并位于接纳腔111内，弹性卡接臂13的自由端131具有上表面1311、下表面1312及连接于上表面1311和下表面1312之间并位于后方的倾斜面1313，倾斜面1313由构件壳体11的下至上的方向向构件壳体11的前上方倾斜，故在手柄20的插接头21插入接纳腔111的过程中，由插接头21顶推弹性卡接臂13的自由端131做靠近构件壳体11的前方弹性变形，具体是由插接头21的凸起舌头211d顶推弹性卡接臂13的自由端131做靠近构件壳体11的前方弹性变形，使得插接头21之锁卡凹槽211的后槽壁表面211b顺畅地越过倾斜面1313与下表面1312的交汇处1314再与倾斜面1313进行面面抵接，因而使插接头21可靠地夹持于倾斜面1313与接纳腔111对应的腔壁之间，再结合自由端131的倾斜面1313与插接头21面面抵接，故借助由构件壳体11单侧延伸出的一个弹性卡接臂13便能实现互联构件10与手柄20之间的扣合连接，以在确保互联构件10与手柄20之间可靠扣合的条件 下实现单点扣合，以简化结构。
值得注意者，当上述的弹性卡接臂13可由构件壳体10的后侧向上延伸出所成时，此时的弹性卡接臂13的自由端131向构件壳体11的前方弯曲并位于接纳腔111内，故不上述的举例为限。当弹性卡接臂13由构件壳体10的后侧向上延伸出时，此时的锁卡凹槽211的槽口211a形成于插接头21的后表面及上表面21b，锁卡凹槽211的前槽壁表面由手柄20的下至上的方向向手柄20的后上方倾斜，锁卡凹槽211的前槽壁表面与倾斜面1313面面抵接，倾斜面1313与下表面1312之间的交汇处1314位于锁卡凹槽211的前槽壁表面与下槽壁表面211c之间的空间，故不以此为限。
另，构件壳体41的前方、后方、左侧及后侧的建立是以剃须刀100在向下剃刮胡须时，互联构件40面对皮肤的一方称为前方，互联构件40背对皮肤的一方称为后方，此时位于左侧的称为互联构件40的左侧，位于右侧的称为互联构件40的右侧，位于上侧的称为互联构件40的上端，位于下侧的称为互联构件40的下端。
以上所揭露的仅为本申请的较佳实例而已，当然不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，仍属于本申请所涵盖的范围。
