The butt joint structure of the traditional cabin body enables the phase angle between the cabin bodies to be fixed before assembly, and because the shells of the cabin bodies are processed separately in batches, if the butt joint phase angle is determined during processing of the shells of the cabin bodies, the processing difficulty is high, and the processing cost is high. For example, with the adoption of the cabin body butt joint structure connected by the screws, when the connection screw holes of the two cabin bodies are processed, the phase angle is accurately positioned twice, and the phase angle accuracy of final assembly is difficult to guarantee after twice error accumulation. For the cabin body butt joint structure adopting threaded connection, the conventional thread machining precision is difficult to meet the phase angle precision of two sections of cabin bodies after the threads are screwed down.
