This method causes the straightening equipment to be large in size and heavy in weight, making it difficult to carry. In addition, the existing straightening equipment can only perform a single process on the longitudinal or lateral horizontality of the pipe. When the pipe is bent in two directions, it is necessary to straighten one direction and then flip the pipe, thereby performing a secondary straightening process, which affects the straightening efficiency of the pipe. Therefore, it is necessary to design a straightening mechanism to solve the above problems. Utility Model Content
