实施例7
如图7和图13所示，本实施例与实施例6的结构基本相同，不同之处在于，插接头7的头部具有若干个沿周向均匀分布的卡柱14，当卡柱14在外力作用下时能向连接螺母10的轴心线方向收拢从而使插接头7的头部进入到卡台13中，当外力失去时，所述的卡柱14能向远离连接螺母10的轴心线方向扩张从而使卡柱14与卡台13卡接配合。本实施例中，卡柱14的数量为3个以上并间隔均匀排列。
调节螺栓9与连接螺母10螺接的一端具有一个插销件15，所述的插接头7的头部具有中心通道16，所述的卡柱14围绕中心通道16均匀设置，当调节螺栓9进入到连接螺母10中的合适位置时，所述的插销件15能插入到中心通道16中并压迫卡柱14向远离连接螺母10的轴心线方向移动。
具体的说，卡台13的端部上具有呈到圆台锥形的第二卡台斜面132，卡台13的底部为平面，插接头头部72靠近卡台13的一端呈平面状，当连接螺母10下拉时，则卡台13与插接头7形成卡接配合，第二卡台斜面132的设计便于插接头头部72插入到卡台13中。 优选方案，在卡台13的底部设有一个呈环形并向外凸出的卡台挡圈133，在插接头头部72靠近卡台13的一侧设有呈环形的且大小与卡台挡圈133相配适的插接头凹槽73，从而进一步稳固插接头7与卡台13的卡接配合。
插销件15一端固定在调节螺栓9的端部上，插销件15可以是插接、或螺接或焊接等方式与调节螺栓9实现固定连接。插销件15的另一端设有三角锥体151，该三角锥体151最大处的直径不小于中心通道16的孔径，三角锥体151进入中心通道16后，椎体外壁与卡柱14接触，推动卡柱14，对卡柱14起到定位作用，从而使卡柱14形成具有固定形状的插接头头部72。
实施例8
如图8和图14所示，本实施例与实施例7的结构基本相同，不同之处在于，卡台13靠近插接头头部72的一端具有第三卡台斜面134，插接头头部72靠近卡台13的一侧具有与第三卡台斜面134斜度相配适的插接头斜面74，第三卡台斜面134与插接头斜面74接触后形成斜面配合式的卡接，卡接更牢固。
具体的说，插接头斜面74设在卡柱14上。
实施例9
如图9和图15所示，本实施例与实施例5的结构基本相同，不同之处在于，插接头7包括插接头端部71和插接头头部72，插接头端部71连接连接头2，插接头头部72插入到中间螺母12中，插接头头部72由若干个沿周向均匀分布的卡柱14组成，当卡柱14在外力作用下时能向连接螺母10的轴心线方向收拢从而使插接头7的头部进入到中间螺母12中，当外力失去时，所述的卡柱14能向远离连接螺母10的轴心线方向扩张从而使卡柱14与中间螺母12卡接配合。本实施例中，卡柱14的数量为3个以上并间隔均匀排列。
调节螺栓9与连接螺母10螺接的一端具有一个插销件15，所述的插接头7的头部具有中心通道16，所述的卡柱14围绕中心通道16均匀设置，当调节螺栓9进入到连接螺母10中的合适位置时，所述的插销件15能插入到中心通道16中并压迫卡柱14向远离连接螺母10的轴心线方向移动。
具体的说，中间螺母12两端均为平面状，卡柱14的外壁具有至少一个平面状的插接头台阶75，若干个卡柱14上的插接头台阶75相互连接形成环形的台阶部，通过台阶部与中间螺母的端面进行卡接配合。
插销件15的另一端设有三角锥体151，该三角锥体151最大处的直径不小于中心通道16的孔径，三角锥体151进入中心通道16后，椎体外壁与卡柱14接触，推动卡柱14，对卡柱14起到定位作用，从而使卡柱14形成具有固定形状的插接头头部72。
如图11和图12所示，连接件的工作原理是通过调节螺栓9的转动从而调整调节螺栓9进入到连接螺母10的长度，并以此来调整连接螺母10的位置，当连接螺母10的位置合适时，插接头7与连接螺母10卡接配合，从而实现两个预制构件100的固定连接。
具体的说，以实施例8所示的连接件为例，如图11所示，插接头7已经插入到连接螺母10中，但连接螺母10与插接头7并与卡接，此时，两个预制构件100之间的距离是不固定的。如图12所示，转动调节螺栓9或者转动连接螺母10，均可以调整调节螺栓9进入到连接螺母10中的位置，实际上就是在调整连接螺母10的位置，在图12中，连接螺母10被下拉后与插接头头部72接触并卡接配合，此时，两个预制构件100之间的位置固定，实现 固定连接。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
