A kind of Fang removing device structure,Its include a screw,One horizontal supporting plate,One first spiral lock,One second spiral lock and an elastic element,It is locked in root of the tooth through the tip of screw,And what screw is arranged by the wherein a positioning hole on horizontal supporting plate,And will combine Hou the first spiral lock,Second spiral lock and elastic element are locked by the upper end of screw,Most Hou penetrates the first spiral lock of rotation and the second spiral lock,It forces screw to move up while also root of the tooth being driven to move up,And the elastic element of bottom in the second spiral lock of what is set through compression simultaneously,Make root of the tooth by upward pulling force,Thereby to reach the purpose for pulling out root of the tooth.一種牙根拔除裝置結構，其包括有一螺釘、一水平支撐板、一第一螺鎖件、一第二螺鎖件與一彈性元件，透過螺釘之尖部鎖入牙根內，並由水平支撐板上之其中一定位孔套設於螺釘，以及將組合後之第一螺鎖件、第二螺鎖件與彈性元件由螺釘之上端鎖入，最後透過轉動第一螺鎖件與第二螺鎖件，迫使螺釘向上移動同時也帶動牙根向上移動，且同時透過壓縮設置於第二螺鎖件內底部之彈性元件，使牙根受到向上的拉力，藉此以達到拔除牙根之目的。
