另外，也可以通过在拉杆上开设纵向非圆形孔，对应的转轴也非圆柱转轴，以防止转轴与拉杆之间产生相对转动，进一步通过在非圆形孔与非圆柱转轴之间设置冗余空间，使拉杆相对转轴能够进行水平的前后微调。
在上述任一技术方案中，优选地，拉杆的侧壁设置有第一限位结构；第三插孔内设置有与第一限位结构配合的第二限位结构；第三插孔内还设置有第三限位结构；第一限位结构与第二限位结构之间设置有弹性缓冲件。

在上述任一技术方案中，优选地，所弹性缓冲件为套接于拉杆上的弹簧或设置于第三插孔内的弹性填充物。
在该技术方案中，通过将弹性缓冲件设置为套接于拉杆上的弹簧或设置于第三插孔内的弹性填充物，一方面，能够满足对转轴限位的要求，另一方面，通过弹簧或弹性填充物的弹性形变，在需要拉杆前后移动调整时，能够满足调整需求。
在上述任一技术方案中，优选地，第二连接部为圆柱插头；固定轴的周向设置有缺口部，以在拉杆旋转后，使圆柱插头插入固定轴；缺口部设置有第一卡接面，第一卡接面通过与圆柱插头的内侧端面配合，实现拉杆卡接；缺口部还设置有与第一卡接面具有指定夹角的第二卡接面，固定轴通过旋转指定夹角的角度，使内侧端面与第二卡接面卡接配合，其中，第一卡接面与固定轴的轴心的距离大于第二卡接面与固定轴的轴心的距离，以通过固定轴旋转，减小第一外壳与第二外壳之间的组装间隙。
在该技术方案中，将第二连接部设置为圆柱插头，并且圆柱插头的插头直径大于相邻的连接杆的直径，通过拉杆转动，在实现第一连接部与第二连接部连接的同时，将圆柱插头通过固定轴上设置的缺口部，插入固定轴，在缺口部设置有与拉杆方向垂直的第一卡接面，通过第一卡接面与圆柱插头的内侧端面的配合，实现拉杆的固定，从而实现了第一锁扣部与第二锁扣部在第一方向的连接，操作方便，可靠性高。

具体地，当转轴旋转90°时，圆柱插头卡接在固定轴的第一方向位置，此时第一卡接面至固定轴的轴心距离比较大，通过旋转固定轴90°后，圆柱插头固定在固定轴第二卡接面，此时第二卡接面至固定轴的轴心距离被缩小，实现拉紧的效果。
在上述任一技术方案中，优选地，在第二卡接面的卡接区域还设置有与圆柱插头的头部圆角曲面配合的接触面，以通过头部圆角曲面与接触面过盈配合，实现锁死。
