[0002] During the exploration and development process, oil needs to be transported using oil pipelines, and oil pipelines are generally fixedly connected through oil casing couplings. The length of oil pipelines is generally long, and generally multiple sets of oil casing couplings are required for fixed connection. Moreover, they will be worn out during long-term use, so the demand for oil casing couplings naturally increases.

The existing clamping tooling of the oil casing coupling is generally formed in one piece with the mechanical equipment for processing the oil casing coupling, and is fixedly connected to each other. The clamping tooling is only applicable to mechanical processing equipment of corresponding specifications, and cannot be applied to different mechanical processing equipment according to actual conditions.
