[0002] Oil wells are holes drilled according to the well layout system of oil field development planning for the extraction of oil. They are channels for oil to rise from the bottom of the well to the wellhead. Oil wells include single-tube oil wells and double-tube oil wells. Oil wells are often damaged during use, and operators are required to frequently repair the wells. During the repair process, the largest and most arduous workload for operators is to install and remove threads of oil pipes and drill tools. In the past, pipe pliers or chain pliers were used, which were not only labor-intensive but also dangerous.
