[0002] At present, when a small geological drilling rig uses a power head for drilling, the process of pulling the drilling rig out of the well is time-consuming and inefficient. For example, when pulling out the drill, the power head of the drilling rig is pulled out of the well by the winch. It is necessary to install a lifting ring and a tilting cylinder under the power head, and put the drill rod in the lifting card, and the lifting ring and the lifting card are used to drive the drill rod out of the well.
