首先对夹线机构进行说明，滑套8、滑动杆14、第二滑动杆17三者的运动类似圆珠笔，初始状态下，线槽7两侧的滑套8对应的滚轮32抵靠在一起，第二导向坡16抵靠在奇导向坡上，导向凸块18抵靠在第二滑槽19远离滑动杆14的一端，此时，第二滑动杆17抵靠在限位凸条25底端，当第二滑动杆17受到相应的力朝向滑套8运动时，导向凸块18沿着第二滑槽19滑动，弹簧被压缩，第三导向坡23朝向第二导向坡16运动，然后第三导向坡23与第二导向坡16相遇，然后第三导向坡23推动第二导向坡16沿着齿边11运动，在第三导向坡23的作用下，第二导向坡16与其对应的齿边11存在压力，在齿边11的阻挡下，第二导向坡16不会在第三导向坡23上滑动，凸起15沿着齿边11滑动，当凸起15与齿边11脱离之后，第二导向坡16沿着第三导向坡23滑动，滑动到第二齿边22与第三导向坡23交界处，滑动杆14旋转一定角度，然后推动第二滑动杆17朝向滑套8运动的力消失，在第二弹簧的作用下，凸起15朝向第二滑动杆17方向运动，带动第二滑动杆17朝向远离滑套8方向运动，当第二导向坡16抵靠在偶导向坡上的时候，第二导向坡16与第三导向坡23分离，第二导向坡16沿着偶导向坡滑动到滑槽13，然后沿着滑槽13运动到槽底，当第二导向坡16运动到槽底的时候，第二导向坡16重新与第三导向坡23抵靠在一起，相比初始状态，滑动杆14朝向滑套8移动一段距离，即，滑动杆14裸露在滑套8外的长度“变短”了。另外，在弹簧的作用下，导向凸块18沿着第二滑槽19滑动到初始位置，滚轮32重新抵靠在一起。
当第二滑动杆17再次收到朝向滑套的力，第二滑动杆17朝向滑套8运动，当第二导向坡16与第三导向坡23相遇，然后第二导向坡16被第三导向坡23推动，第二导向坡16沿着齿边11运动，当第二导向坡16脱离齿边11时，第二导向坡16沿着第三导向坡23滑动，运动到第三导向坡23与第二齿边22交界处，此时，滑动杆14旋转一定角度，然后第二滑动杆17朝向远离滑动杆14方向运动，在第二弹簧的作用下，凸起15朝向第二滑动杆17方向运动，当第二导向坡16抵靠在奇导向坡的时候，第二导向坡16与第三导向坡23分离，最终第二导向坡16运动到奇导向坡与齿边11的交界处，在弹簧的作用下，导向凸块18重新回到初始位置，滚轮32重新抵靠在一起。滑动杆14裸露在滑套8外的长度重新“变长”了。
以此往复，每次第二滑动杆17“伸缩”一下，滑动杆14裸露在滑套8外的长度，在“长”“短”之间来回切换。
本实施例中，利用上述空气间隙避雷器的安装装置进行避雷器安装方法如下：
一种空气间隙避雷器的安装方法，其步骤如下:步骤a，在地面上，滑动调节套33调节调节套33到手持杆1底端的距离，拧紧调节螺栓，将避雷器3底端放置在托盘4上，固定绳5穿过限位环然后将避雷器3系住；步骤b，地面人员通过滑轮组将避雷器3和空气间隙避雷器的安装装置提升到横担29上，由横担29上的电工接收并预备安装的位置；步骤c，在横担29上，确认调节套33到手持杆1 底端的距离无误，由一名电工拉住手持杆1，另一名电工拉住绝缘绳30，还有一名电工扶住避雷器3，慢慢下放避雷器3，滚轮32与分裂导线2相遇，分裂导线2位于滚轮32之间，分裂导线2挤压滚轮将滚轮分开，滚轮挤压对应的第二滑动杆17，当滚轮32向下运动时，滚轮32先被分裂导线2分开，然后又合拢，此时，第二滑动杆17完成一次“伸缩”，滑动杆14裸露在滑套8外的长度变短，此时，滑动杆14端面与限位凸条25对应侧齐平，在第三弹簧的作用下，滑套8朝向手持杆1方向运动，滑动杆14贴着限位凸条25滑动，滚轮32向上运动，最终将分裂导线2挤压在线槽7的槽底，从而将分裂导线2夹住，当手持杆1晃动的时候，由于此时，第三导向坡23与第二导向坡16抵靠在一起，此时当滚轮想要朝向滑套8运动的时候，第三导向坡23推不动第二导向坡16，因为限位凸条25将第二滑动杆17抵住了，防止夹线机构松开分裂导线2；步骤d，电工通过螺栓将避雷器3低压端安装在横担29上，确认无误后，解开固定绳5，然后转动手持杆1，此时，夹线机构不动，托盘4转动180度，避开避雷器3，防止向上拉的时候带动避雷器，然后向上用力拉手持杆1，分裂导线2推动滚轮32朝向线槽7的槽口运动，第二滑动杆17在限位凸条25上滑动，当第二滑动杆17运动到限位凸条25的端部的时候，分裂导线2将滚轮32分开再合拢，夹线机构与分裂导线2分开，第二滑动杆17完成一次“伸缩”，滑动杆14裸露在滑套8外的长度重新变长，滑动杆14重新抵靠在限位凸条25的底端。从而完成回收空气间隙避雷器的安装装置。
