[0006] Furthermore, the articulated mechanism includes a cylinder, a cylinder upper seat and a cylinder lower seat, one end of the cylinder is hinged to the cylinder upper seat through a first cylinder pin, and the other end is hinged to the cylinder lower seat through a second cylinder pin, the cylinder upper seat is fixedly arranged on the front traction frame, and the cylinder lower seat is fixedly arranged on the rear frame.

[0007] Furthermore, the flipping mechanism comprises a front traction frame flipping seat and a front traction frame flipping seat pin. The front traction frame flipping seat is fixedly arranged on the front traction frame and is hinged to the rear frame through the front traction frame flipping seat pin.

[0008] Furthermore, a first traction pin is provided at the lower portion of the front traction frame, and a second traction pin is provided at the lower portion of the front end of the rear frame.

[0009] Compared with the prior art, the advantages of the utility model are as follows:

[0010] (1) It has various forms. It can be used as a flatbed semi-trailer of normal length or as an extended flatbed semi-trailer. As a normal flatbed semi-trailer, it can transport a 20-foot container and various bulk cargoes. As an extended flatbed semi-trailer, it can transport a 40-foot container / 2 20-foot containers and various bulk cargoes.

[0011] (2) Compared with conventional semi-trailers, it has two towing pins, making it more flexible. The size of the vehicle can be changed according to road conditions, cargo size, etc. to meet transportation needs. When space is limited, the front towing frame can be raised and it can be used as a flatbed semi-trailer of normal length to improve vehicle passability; when there is no space requirement, the front towing frame can be lowered and it can be used as an extended flatbed semi-trailer to improve vehicle loading capacity.
