下面结合附图对本申请做进一步说明：
如图1至5所示，本申请的一个优选实施例包括用于连接第一分体件1和第二分体件2的第一连接模块31和第二连接模块32，第一分体件1和第二分体件2可以为任意两个需要固接的分体构件，第一分体件1和第二分体件2为套设连接，当该模块化连接机构3用于切削刀具上时，第一分体件1和第二分体件2可以为刀柄13和连接主轴，通过模块化连接机构3能够方便的对两者进行连接，让刀柄13能够跟随连接主轴活动。
第一连接模块31和第二连接模块32滑动连接，第一连接模块31和第二连接模块32容置于第一分体件1在垂直于轴心所在平面的方向上开设的安装通道11内，第一连接模块31和第二连接模块32预置于安装通道11内，连接前不易丢失掉落。
安装通道11经过第一分体件1的轴心，使模块化连接机构3设置于安装通道11内时不会使第一分体件1的重心发生偏移，重量均衡分布，重心能够保持在轴心位置，提升刀柄13和连接主轴在转动中的稳定，减少活动载荷。
第一连接模块31和第二连接模块32适于相互远离，第一连接模块31和第二连接模块32初始状态下为靠近状态，当对第一分体件1和第二分体件2进行连接时，可控制第一连接模块31和第二连接模块32相互远离，第一连接模块31和第二连接模块32适于在相互远离时伸至第一分体件1外侧与第二分体件2抵触配合从而使第一分体件1和第二分体件2固接，第一连接模块31和第二连接模块32相互远离进行抵触配合的形式能够保证刀柄13和连接主轴在转动时，第一连接模块31和第二连接模块32受到离心力的影响具有相互远离的趋势，从而将离心力转化为对第二分体件2抵触的压力，从而提升连接结构的强度，提升第一分体件1和第二分体件2的固接稳定性。
第一连接模块31和第二连接模块32外侧皆设置有抵触部33，第二分体件2上开设有卡接槽21，抵触部33适于与卡接槽21偏心嵌合卡接并阻止第二分体件2相对第一分体件1活动，抵触部33的轴心为A1，卡接槽21的轴心为A2，A1位于A2的左侧，嵌合卡接时能够使抵触部33的左侧优先与卡接槽21的左侧配合抵触，由于卡接槽21具有加工误差，在加工时可以对卡接槽21预留加工余量，利用偏心嵌合的方式能够利用该加工余量避免加工装配误差导致的固接稳定性降低，让第一分体件1和第二分体件2能够进行整体的接触固接，减少两者之间的装配缝隙，降低两者之间可能发生活动的概率。
抵触部33四周具有引导环面331，引导环面331能够降低抵触部33和卡接槽21配合的难度，随着抵触部33嵌入卡接槽21内深度的增加，引导环面331能够使第一分体件1和第二分体件2之间发生轴向移动配合，第一分体件1和第二分体件2之间的缝隙能够逐渐缩减，直至发生紧密抵触配合实现固接，降低配合难度，同时引导环面331的存在能够使抵触部33依据嵌入深度适应卡接槽21的的加工误差，实现较为完美的连接装配。
引导环面331和抵触部33的轴心之间的夹角为α，0°＜α＜45°，该夹角范围内，抵触部33能够使第二连接模块32在安装通道11内的移动距离大于第一分体件1和第二分体件2发生的轴向移动距离，增加调节精细度，同时提升抵触部33对第二分体件2的卡接强度，降低抵触部33变形损坏的概率。
α的优选角度为20°，该角度下通过引导环面331对第二分体件2施加的压力的分解，让第一连接模块31和第二连接模块32之间的滑动连接结构处的受力与抵触部33处受到的剪切力相平衡，获得更好的稳定性，避免结构损坏。
第一连接模块31和第二连接模块32之间的滑动连接形式优选为丝杆连接，丝杆连接能够将第一连接模块31的转动转化为第二连接模块32的滑动，实现两者的靠近或远离，第一连接模块31和第二连接模块32适于不断开的相互靠近或远离，保证第一连接模块31和第二连接模块32之间的连接关系的稳定，避免连接结构失效，第一连接模块31和第二连接模块32相互靠近时，抵触部33能够解除对第二分体件2的抵触配合，从而使第一分体件1和第二分体件2解除固接，让两者能够拆卸分离，方便第一分体件1和第二分体件2的拆卸更换。
进一步的，第一连接模块31和第二连接模块32之间的滑动连接形式优选为螺纹丝杆连接，第一连接模块31和第二连接模块32适于沿安装通道11移动，安装通道11起引导作用，提升第一连接模块31和第二连接模块32的活动稳定性，第一连接模块31适于在安装通道11内转动从而远离或靠近第二连接模块32，利用螺纹丝杆的工作原理，通过第一连接模块31的转动使第二连接模块32能够与其产生相对滑动，转动操作滑动的形式不易误操作，也能够避免第一连接模块31和第二连接模块32发生自主移动影响连接结构的稳定性。
第一连接模块31和第二连接模块32的主体形状优选为圆柱形，第一连接模块31可以为类螺栓结构，第二连接模块32可以为圆柱环，安装通道11一侧设置有限位件34，限位件34适于阻止第二连接模块32转动，由于第一连接模块31和第二连接模块32为螺纹连接，第二连接模块32可能随着第一连接模块31的转动而发生转动，从而无法实现丝杆滑动，限位件34的存在能够阻止该情况的发生。
第二连接模块32一侧开设有定位槽321，限位件34一端适于与定位槽321配合卡接，限位件34优选设置于第一分体件1的轴心处，第一连接模块31和第二连接模块32的抵触部33的长度相同且分别位于限位件34的两侧，使第一连接模块31和第二连接模块32能够受力均匀的抵至两侧的第二分体件2的卡接槽21内。
刀柄13内无液体通道12时，限位件34可以为块状结构；刀柄13内开设有液体通道12时，限位件34可以为环状结构，限位件34与液体通道12同轴心，限位件34不干涉液体通道12的液体流过，而第一连接模块31和第二连接模块32远离实现第一分体件1和第二分体件2的固接时，第一连接模块31和第二连接模块32之间会形成缝隙，液体可从缝隙处流过实现流通。
抵触部33适于在第一连接模块31和第二连接模块32相互靠近时收容至安装通道11内，避免抵触部33影响第一分体件1和第二分体件2之间的分离拆卸。
第一连接模块31上设置有用于控制其转动的操作孔332，操作孔332沿第一连接模块31的轴心方向设置，操作孔332优选为六边形孔，通过六角螺杆能够方便的对第一连接模块31进行转动，能够有效避免误操作导致连接结构松动分离。
第二分体件2上开设有连通操作孔332与外界的通孔22，通孔22可以连通卡接槽21，抵触部33嵌合抵触至卡接槽21内时能够方便的从外界对操作孔332进行操作。
第一连接模块31和第二连接模块32沿周向嵌设有密封圈35，密封圈35过盈配合于第一连接模块31与安装通道11之间以及第一连接模块31与安装通道11之间，密封圈35优选使用橡胶材质，能够在第一连接模块31和第二连接模块32与安装通道11之间增加滑动阻尼，阻止第一连接模块31和第二连接模块32随意滑动，同时具有密封效果，当刀柄13内的液体通道12经过模块化连接机构3时，能够阻止液体从第一连接模块31和第二连接模块32处流出。
第二连接模块32的抵触部33的外端可以为封闭式结构，方便与第一连接模块31做出区分，避免发生误操作；第二分体件2在与第二连接模块32的抵触部33抵触配合的卡接槽21处可以为封闭结构，阻止从外界对第二连接模块32进行操作，避免发生误操作。
