Description

Technical Field

[0001] The utility model relates to the technical field of oilfield operation tools, in particular to a multifunctional pipe clamp used for oilfield well site operations. Background Art

[0002] Pipe clamps are a common tool used in oilfield operations. In actual use, it is found that when using traditional pipe clamps to tighten pipe fittings, the jaws and pipe fittings are prone to slippage. This defect not only affects the tightening effect, but also easily leads to the safety hazard of the pipe clamp hitting people. In addition, when using pipe clamps, it is often necessary to install a force tube on the handle of the pipe clamp to extend the power torque to achieve the purpose of labor saving. However, when the force tube is installed on the handle of the traditional pipe clamp, after applying torque, the force tube is easy to slip off the handle, posing a hidden danger to the personal safety of workers.
