为了使本公开的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本公开进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本公开。

为了说明本公开所提供的技术方案，以下结合具体附图及实施例进行详细说明。
在一个或多个实施例中，本公开提供了一种离合切换组件，对于齿轮自紧钻夹头、扁爪自紧钻夹头、内螺纹自紧钻夹头和外螺纹自紧钻夹头均可采用该离合切换组件，实现其前体201和后体202之间的同步转动，或各自独立转动。本公开实施例提供的离合切组件，具有分离效果可靠、稳定的特点，使用该离合切换组件的钻夹头，有利于保证正常的生产进度，提高生产效率。
参见图18和图19所示，本公开实施例的离合切换组件包括：第一接合子101、第二接合子102和分离件103。第一接合子101被配置为与钻夹头的前体201相连接，且能够与前体201同步转动；钻具具有工作端和锁紧端，钻具的工作端能够使物体上钻出孔，而钻具的锁紧端插入钻夹头中，通过钻夹头的夹爪对锁紧端进行夹紧固定，实现钻具随着钻夹头的前体201一起转动。当钻具安装于钻夹头上后，从钻具的锁紧端向钻具的工作端观察时，钻夹头顺时针转动的方向为钻夹头的正转方向，钻夹头逆时针转动的方向为钻夹头的反转方向。而后体202沿钻夹头的正转方向转动时，实现夹爪对钻具的夹紧；后体202沿钻夹头的反转方向转动时，实现夹爪对钻具的松开。第二接合子102与第一接合子101相对设置，第二接合子102与第一接合子101之间具有间隙，这样使得分离件103能够伸入。第二接合子102被配置为与钻夹头的后体202相连接，且能够与后体202同步转动。第一接合子101与第二接合子102之间具有使前体201与后体202同步转动的接合状态，以及具有使前体201与后体202各自独立转动的分离状态，在分离状态下前体201与后体202各自独立转动，也就是前体201与后体202之间能够发生相对转动，后体202相对前体201正转或反转。钻夹头的前体与后体同轴设置。
当第一接合子101与第二接合子102相接合时，第一接合子101与第二接合子102保持相对固定，这样前体201与后体202便能够同向转动，即前体201与后体202一起正转或反转；当第一接合子101与第二接合子102相分离时，第一接合子101与第二接合子102之间能够相对转动，这样后体202便能够相对于前体201正转或反转，即可以实现后体202对钻具的夹紧或松开。分离件103的至少部分结构被配置为逐渐伸入或退出第一接合子101与第二接合子102之间，使得第一接合子101之间和第二接合子102之间的距离改变，以使第一接合子101与第二接合子102在接合状态和分离状态之间切换，通过分离件103插入或脱出第一接合子101与第二接合子102之间，改变第一接合子101之间和第二接合子102之间的距离。当逐渐置入分离件103时，当置入第一接合子101与第二接合子102之间分离件103的部分的最大高度不小于第一接合子101与第二接合子102之间的最小分离高度，第一接合子101与第二接合子102便处于分离状态，第一接合子101与第二接合子102便能够发生相对转动。第一接合子101和第二接合子102之间的分离高度方向与分离件103的高度方向相平行。第一接合子101和第二接合子102之间的分离高度的方向，也就是第一接合子101和第二接合子102之间的间距的方向。分离件103的至少部分结构(设定的部分)逐渐伸入第一接合子与第二接合子之间时，可以实现第一接合子与第二接合子逐渐分离；而当分离件103的至少部分结构退出第一接合子与第二接合子之间时，可以是该部分结构部分退出或完全退出第一接合子与第二接合子之间。
需要说明的是，分离件伸入或退出实现接合状态与分离状态的切换的实施方式主要包括两种。第一种方式，分离件的至少部分结构伸入第一接合子与第二接合子之间时，第一接合子与和第二接合子之间为分离状态；而分离件的至少部分结构退出第一接合子与第二接合子之间时，第一接合子与和第二接合子之间为接合状态。第二种方式，分离件的至少部分结构退出第一接合子与第二接合子之间时，第一接合子与和第二接合子之间为接合状态；而分离件的至少部分结构伸入第一接合子与第二接合子之间时，第一接合子与和第二接合子之间为分离状态。
在一些实施例中，第一接合子与前体周向固定，且第一接合子与前体轴向固定；第二接合子102与后体202周向固定，且第二接合子102能够相对于后体202沿轴向移动设定距离，由于第二接合子102 与后体202周向固定，因此后体202转动时能够带动第二接合子102一起转动，由于第一接合子与前体周向固定，因此前体转动时能够带动第一接合子一起转动。需要说明的是，在一些其它实施方式中，第一接合子101与钻夹头的前体201为一体设置。
在另外一些实施例中，第一接合子与前体周向固定，且第一接合子能够相对于前体沿轴向移动设定距离；第二接合子102与后体202周向固定，且第二接合子102与后体202轴向固定，由于第二接合子102与后体202周向固定，因此后体202转动时，能够带动第二接合子102一起转动。
需要说明的是，在一些其它可能的实施方式中，第一接合子与第二接合子相接合或分离的方式采用第一接合子周向固定，且第一接合子能够沿前体的轴向运动，而第二接合子的周向固定，且第二接合子能够后体的轴向运动。
本公开至少一个实施例提供的离合切换组件，通过将第一接合子101与钻夹头的前体201周向固定，将第二接合子102与钻夹头的后体202周向固定，并使第一接合子或第二接合子102能够沿钻夹头的轴向移动，这样第一接合子101与第二接合子102之间相接合后，实现前体201与后体202同步转动，从而使得钻夹头在正转和反转时都不易造成钻具的松动，同时利用分离件103以伸入或退出第一接合子101和第二接合子102之间的间隙，以改变第一接合子101与第二接合子102之间的状态，使得第一接合子101与第二接合子102在接合状态与分离状态之间切换，采用分离件103伸入或退出可以方便的实现接合与分离之间切换；，或通过一分离件使第一接合子相对于前体轴向移动，以使得第一接合子与第二接合子在分离状态和接合状态之间切换。当需要松开拆卸掉钻具时，使分离件103伸入第一接合子101和第二接合子102之间的间隙，这样第一接合子101与第二接合子102相分离，从而实现后体202能够相对于前体201独立转动，从而便于松开钻具。
在一些实施例中，离合切换组件还包括复位件104，复位件104具有弹性。复位件104被配置为使第一接合子101与第二接合子102之间的距离逐渐减小，以使第一接合子101与第二接合子102由分离状态向接合状态切换。通过复位件104利于保证接合的稳定性。
在一些实施例中，复位件104的材质为金属，例如为不锈钢或其它材质。复位件104为波形垫片。第一接合子101和第二接合子102均具有相对的内侧和外侧，第一接合子101的内侧与第二接合子102的内侧相对。复位件104位于第二接合子102的外侧或复合位于第一接合子101的外侧。当第一接合子101与第二接合子102分离时，第一接合子与第二接合子之间的距离增大，复位件104能够被压缩，具有弹性势能。
需要说明的是，在一些其它实施方式中，复位件104还可以为弹簧等具有弹性的零件。在另外一些其它可能的实施方式中，复位件位于第一接合子与第二接合子之间。
参见图1、图8、图20、图23、图31、图36、图43和图50所示，在一个实施例中，当分离件103至少部分结构逐渐从第一接合子101和第二接合子102之间退出时，被压缩的复位件104的弹性势能被释放，使得第一接合子101和第二接合子102接合。
参见图54和图61所示，在一个实施例中，当分离件103至少部分结构逐渐伸入第一接合子101和第二接合子102之间的设定位置时，被压缩的复位件104的弹性势能被释放，使得第一接合子101和第二接合子102接合。
在一些实施例中，第一接合子101和第二接合子102均为片状结构；第一接合子101与第二接合子102之间具有止动结构，以使第一接合子101与第二接合子102之间能够接合而同步转动。通过止动结构实现第一接合子101与第二接合子102相接合时，前体201与后体202同步转动。
在一些实施例中，止动结构为齿结构105，第一接合子101的内侧和第二接合子102的内侧均具有齿结构105，第一接合子101上的齿结构105与第二接合子102上的齿结构105相啮合实现两者的第一接合子101与第二接合子102的接合，即第一接合子101与第二接合子102在周向上保持相对固定，两者能够绕前体201的轴线同步转动。当第一接合子101上的齿结构105与第二接合子102上的齿结构105相分离时，实现第一接合子101与第二接合子102之间的分离。
在一个实施例中，第一接合子101和第二接合子102的外轮廓呈圆形，这样利于保证钻夹头转动的 稳定性；齿结构105即为设置在片状结构的片面上的多个齿，且多个齿呈圆形分布在片面上，齿可以为棘齿。需要说明的是，在一些其它实施方式中，第一接合子101和第二接合子102的外轮廓均呈正多边形。
参见图5、图6和图7所示，在一些实施例中，分离件103为具有倾斜面106的楔块。楔块被配置为沿前体201的径向伸入或退出第一接合子101与第二接合子102之间的间隙。第一接合子101上的内侧的表面具有第一导向滑槽108，楔块能够沿第一导向滑槽108移动，以实现楔块的径向移动，楔块沿前体201的径向移动方向的一侧与第一接合子101上的轴向凸部111之间设置有第一弹簧109，轴向凸部111和第一接合子101上均具有供第一弹簧109插入的弹簧定位孔110。通过楔块与第二接合子102相接触的部分之间设置的倾斜面106实现对第二接合子102的作用，实现分离。这样通过手用力握住楔块，楔块进入第一接合子101与第二接合子102之间的间隙，使第一接合子101和第二接合子102分离，当手松开时楔块在第一弹簧109的作用下弹出，实现第一接合子101和第二接合子102的接合。
参见图9所示，在一些实施例中，离合切换组件还包括转动部112，转动部112被配置为在其自身绕前体201的轴线转动时，转动部112能够使分离件103的至少部分结构伸入或退出第一接合子101与第二接合子102间的间隙。转动部112绕前体201的轴线转动时，能够使分离件103的部分结构伸入或退出第一接合子101与第二接合子102之间实现两者的分离或接合。
参见图8和图12所示，在一些实施例中，转动部112为套状结构或弧形结构。转动部112的转动方向具有分离方向和接合方向；分离方向与钻夹头的正转方向相同，接合方向与钻夹头的反转方向转动相同。转动部112沿钻夹头的正转方向转动时，实现第一接合子101与第二接合子102之间的分离；转动部112沿钻夹头的反转方向转动时，实现第一接合子101与第二接合子102之间的接合。

需要说明的是，在一些实施例中，导向槽113的长度延伸方向可以弧形。另外，当第一接合子101与前体201为一体结构时，导向槽113的部分结构还开设在前体201上。转动部112上的定位孔114，还可以设置定位槽的形式。再者，在一些其它可能的实施方式中，当第二接合子周向和轴向固定，而第一接合子周向固定时，采用在第二接合子上设置导向槽，并利用旋转体实现第一接合子沿轴向移动。
