Description

Technical Field

[0001] This utility model relates to the field of tubing wrench technology, specifically a tooth-less tubing wrench that facilitates easy operation for adding and removing threads. Background Technology

[0002] Tubing wrenches are tools specifically designed for tightening and loosening tubing threads. Connecting and disconnecting tubing is an essential part of oil extraction and drilling. Therefore, using tubing wrenches to apply and remove threads is a fundamental and important task in the oil industry. However, existing tubing wrenches are typically lifted using a workover machine, and then pushed to the position for applying and removing threads by technicians. After use, the wrenches need to be manually pulled back. This process is not only labor-intensive but also time-consuming and inconvenient, posing certain safety risks. Utility Model Content
