所述转动杆12一端穿设机架2于第一夹头11一侧设有安装板17，另一端固设有感应环31，所述安装板17上固设有基准板15，所述基准板15两端向两侧凸起对称设置有顶尖16，所述基准板15中心设置有圆弧形长槽101，所述顶尖16沿圆弧形长槽101两侧圆弧中心连线对称设置，即顶尖16至圆弧中心连线相等，所述顶尖16间连线垂直于管件加工面，所述圆弧形长槽101用于调节顶尖16间连线至转动杆12轴心间距离。
所述转动杆12上套设有第一弹簧18，所述第一弹簧18两端分别顶靠机架2及安装板17，所述第一弹簧18与机架2及安装板17配合时优选采用垫片，以减少转动杆12转动时第一弹簧18与机架2及安装板17间的相对摩擦力。
所述感应环31为铁质圆环，即一种可被磁铁吸引的环状铁圈，且转动杆12上设有可安装感应环31的固定板。
所述第一夹头11的从动轴内穿设有滑动杆21，所述滑动杆21为六角杆，所述滑动杆21穿设第一夹头11后在靠近管件一侧设置有收集仓22，所述收集仓22通过螺栓固定连接于滑动杆21端部，所述收集仓22收集口水平向上设置； 所述机架2上设有与滑动杆21相配合的导向板23，所述导向板23上设置有六角孔，即滑动杆21滑动穿设于导向板23的六角孔内，所述滑动杆21上设有挡板，所述挡板设置于导向板23靠近第一夹头11一侧，所述挡板与导向板23间设置有第二弹簧24，所述第二弹簧24套设于滑动杆21上且两端分别顶靠挡板及导向板23。

所述压板34面积大于限位板26面积，且压板34优选设置于固定切割头1 的固定座上，即压板34随切割头1的下降而下降，当切割头1下降至一定位置沿轨迹切割时，限位板26也始终位于压板34面积内。
使用如上述一种激光切割设备的方法：使用时，先将管件通过第一夹头11及第二夹头19固定于机架2上，且将基准板15上下方的顶尖16对准需要打孔的基准点，随后切割头1移动至基准板15上方对准基准板15上端的顶尖16，因两端顶尖16在一直线上，因此切割头1对准了管件上的基准点，随后切割头1下移切割，此时压板34与限位板26接触的同时按钮33被按压，电磁铁32通电将感应环31吸合，转动杆12滑动使基准板15远离切割头1一侧，与此同时限位板26压缩第三弹簧27，滑动杆21在第二弹簧24的张力下将收集仓22推入管件内，将切割头1切割后的废料收集入收集仓22内；当正面切割完成后，切割头1上移，随后第二夹头19将管件翻转180°，翻转的同时第一夹头11上的第一齿轮13带动转动杆12上的第二齿轮14转动180°，管件上已切割的孔翻转至另一侧的底部的同时基准板15翻转至已切割的孔的一侧，顶尖16此时对准的始终是已切割的孔的基准点，此时将切割头1移动至基准板15上方对准上端的顶尖16即可对准第二次切割的基准点，随后重复第一次切割的过程，两次切割完成后的孔保证了较高的同心度。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
