A second hinge seat 23 is provided inside the upper end of the storage groove 201.

[0034] The torsion correction frame 30 is located between the front support assembly 10 and the rear support assembly 20. The torsion correction frame 30 has a torsion correction channel 301 for a pipe (not shown) to pass through. The torsion correction channel 301 extends left and right. Specifically, the torsion correction frame 30 includes two horizontal plates 31 and two vertical plates 32. The two horizontal plates 31 are arranged parallel to each other and extend forward and backward. The two vertical plates 32 are arranged parallel to each other and extend vertically. One vertical plate 32 is connected between the front ends of the two horizontal plates 31, and the other vertical plate 32 is connected between the rear ends of the two horizontal plates 31. The two vertical plates 32 and the two horizontal plates 31 form the aforementioned torsion correction channel 301. In this embodiment, the two horizontal plates 31 and the two vertical plates 32 are fixedly connected together by welding. In addition, the cross-section of the torsion correction channel 301 is square so that square pipes can be torsion corrected. In addition, the outer sides of the two vertical plates 32 are respectively arranged on the front ear fork plate 33 and the rear ear fork plate 34.

Then, the pipe is passed through one end of the torsion correction channel 301, and then the pipe is transported along the torsion correction channel 301. During the transportation process, when the pipe is stuck, the front oil cylinder 40 and the rear oil cylinder 50 are controlled to work, so that the front oil cylinder 40 and the rear oil cylinder 50 cooperate to drive the torsion correction frame 30 to rotate forward or backward, thereby realizing the torsion correction operation of the pipe.
