所述第一接触面、第二接触面上均连续设置有若干沿周向排布的齿体11，从而在相邻齿体11之间形成一齿槽12，所述齿体11分别嵌入对应的齿槽12内，将第一接触面、第二接触面卡接，所述齿体11的一个面为平行于螺杆1、套筒5轴向的竖直面，所述齿体11的另一个面为倾斜面，该竖直面与倾斜面之间形成的夹角为锐角。
上述螺杆1的头部4与其螺旋部3一体成型结构；上述齿体11的竖直面与倾斜面之间形成的夹角为62°；上述第一端部8远离第二端部9一端的外径小于套筒5的内径。
使用时，先将螺杆、螺母与套筒组装成为一体的螺栓组件，使螺母上的凸条一端嵌入到套筒上的线槽内，从而使得螺母与套筒保持相对固定，再将螺栓组件穿过待连接部件的安装通孔，然后通过扳手等工具固定套筒、旋转螺杆，随着螺杆的旋转，螺母沿着螺杆的轴向朝着靠近螺杆头部的方向运行，进一步使得凸条嵌入套筒上的线槽内，同时套筒在螺母具有锥形面的第一端部作用下向外张开，当螺母移动到适当位置，停止旋转螺杆，通过螺杆头部与套筒上齿体与齿槽的相互配合，避免螺杆发生反向旋转而使连接松动。
采用上述高稳定性螺栓连接组件时，其可以代替焊接、对一侧为密闭空间的多个部 件(如管柱体)实现紧固连接，且操作方便、紧固效果好，且完全不会出现打滑、跟转甚至松动脱落的情况，进而保证部件之间连接的稳定性；
通过凸条端部与线槽的嵌入卡接，保证螺母与套筒的相对固定，从而实现仅从外侧即可快速实现对螺母与螺栓的拧紧，进一步的，还可以起到导向作用，配合第一端部的锥形面，通过螺母的进一步向套筒方向移动，将套筒一端向外撑开，进一步保证连接结构的稳定性和连接强度，避免发生连接松动等情况；
通过截面为直角三角形的斜齿之间的相互配合，使得螺杆只可以往一个方向旋转，避免安装完成后发生回转导致连接松动，且将齿体直接设置于套筒和螺杆头部，结构一体性和稳定性好；
进一步的，两个凸缘部的设置，可以增大套筒与螺杆头部之间的接触面积，进一步增强其上齿体、齿槽之间卡合的面积，增大螺杆反向转动的阻力，进一步避免螺杆回转导致连接松动。
上述实施例只为说明本实用新型的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本实用新型的内容并据以实施，并不能以此限制本实用新型的保护范围。凡根据本实用新型精神实质所作的等效变化或修饰，都应涵盖在本实用新型的保护范围之内。
