After the pipe supporting hand 320 supports the pipe column, the axis of the transmission arm 311 coincides with the axis of the fixing base 110, the position of the transmission arm 311 after the pipe column is supported is the boundary of the buckling device where the fixing base 110 is located, and the part below the hinge point of the transmission arm 311 is always located between the fixing base 110 and the slip 120, so that the occupied space of the buckling device is reduced, and meanwhile, the transmission arm 311 is prevented from colliding with a person or object on the right side of the positioning plate 130 when rotating.

The pipe supporting arm 310 may be designed as an integral structure, i.e. the driving arm 311 and the supporting arm 312 are integrally formed, or as an integral structure, i.e. the driving arm 311 and the supporting arm 312 are respectively formed and connected to form the pipe supporting arm 310.
