Technical Problem
[0003]本实用新型所要解决的技术问题在于：提供一种反向紧固螺栓装置，它解决了现有技术中常规螺栓紧固工具无法将反向紧固螺栓的问题
Benefits of technology
[0032]通过采用上述技术方案，在滑动壳相对主体发生滑动时，由于齿条与限位齿轮啮合，此时限位齿轮发生转动，当插接柱在复位弹簧的弹性作用下朝向固定板运动时，带动活动板朝向固定板运动，此时活动板带动限位杆朝向限位齿轮方向运动并最终与限位齿轮比表面抵接，当限位孔与限位杆端部对齐时，限位杆端部插入限位孔内限制限位齿轮的转动，在限位齿轮和齿条的啮合作用下，滑动壳将无法运动并保持静止状态，此时装夹凸块和锁紧头的间距也将固定，提高了在转移主体位置的过程中延伸臂和辅助板的稳定性，避免在主体移动过程中延伸臂和辅助板发生运动影响主体的转移运动。
