The invention relates to the technical field of lifting tools, and particularly discloses a lifting tool for underground drill bit fishing. The a lifting tool comprises a supporting base, wherein a rotating mechanism is fixed at the top of the supporting base, and the rotating mechanism is used for rotating a fishing tool to realize rotation in the horizontal direction; and a first supporting plate is fixed to the top of the rotating mechanism, second supporting plates which are symmetrically distributed are fixed to the two ends of the upper surface of the first supporting plate, a rotating rod is fixed between the top ends of the two second supporting plates, a telescopic mechanism is arranged between the top ends of the two second supporting plates and used for stretching out, drawing back and moving the fishing tool in the horizontal direction. and the storage and the use are convenient. According to the lifting tool for underground drill bit fishing, by arranging the rotating mechanism, a rotating motor drives a first threaded rod and a second threaded rod to rotate, therefore a moving plate is driven to slide on the first threaded rod and the second threaded rod, a sliding rod is matched to slide in a sliding groove, a rotating circular disc is driven to rotate, a supporting circular disc is driven to rotate through a rotating shaft, and the lifting tool is rotated, so that the application range is widened.

    本发明涉及起吊工具技术领域,具体公开了一种井下钻头打捞用起吊工具,包括支撑底座,支撑底座顶部固定有转动机构,转动机构用于对打捞工具进行转动,实现水平方向上的转动;转动机构顶部固定有第一支撑板,第一支撑板上表面两端固定有对称分布的第二支撑板,两个第二支撑板顶端之间固定有转动杆,两个第二支撑板顶端之间设有伸缩机构,伸缩机构用于对打捞工具进行水平方向上的伸缩和移动,便于收纳和使用;本发明通过设置转动机构,使转动电机驱动第一螺纹杆和第二螺纹杆转动,从而带动移动板在第一螺纹杆和第二螺纹杆上滑动,配合滑动杆在滑动槽内滑动,带动转动圆盘转动,通过转动轴带动支撑圆盘转动,使起吊工具进行转动提高适用范围。
