Multiple fixing slots are opened on both sides of the inside of the mounting rod. The multiple fixing slots on the same side of the mounting rod are equidistantly distributed along the length of the mounting rod. The two first mounting posts are located in the middle of the mounting rod and correspond to two of the multiple fixing slots opened inside the mounting rod. Fixing posts are slidably arranged inside the two first mounting posts. U-shaped forks are fixedly arranged at the upper ends of the two fixing posts.

[0005] By adopting the above technical solution, two first mounting columns are set, and fixed columns are set inside both first mounting columns. U-shaped forks are set at the upper end of both fixed columns. When in use, after adjusting the position of the U-shaped forks, the front of the vehicle to be towed is lifted with a jack, and then the U-shaped forks are placed under the vehicle. The front axle of the vehicle is then inserted into the U-shaped forks to tow the vehicle. At the same time, because the fixed columns are slidably set inside the first mounting columns, the fixed columns can be removed from the first mounting columns for easy storage when not in use.

[0006] Preferably, multiple second mounting posts are provided on both sides of the mounting rod, and the multiple second mounting posts correspond to the positions of the fixing grooves;

[0007] By adopting the above technical solution, and by setting multiple second mounting posts, the distance between the two fixed posts and the U-shaped fork can be changed by inserting the fixed post into different second mounting posts during use, thus making it suitable for use with vehicles of different specifications and with a wider range of applications.

[0015] By adopting the above technical solution, after the vehicle to be towed is placed on this device, the tow bar can be connected to the rescue vehicle using the connecting buckle, and then the vehicle can be towed away.

[0016] Preferably, mounting brackets are fixedly provided on both sides of the mounting rod, wheel mounting seats are fixedly provided inside the two mounting brackets, and wheels are rotatably provided at one end of the two wheel mounting seats;

[0017] By adopting the above technical solution, the two wheels are symmetrically distributed on both sides of the mounting rod, which can effectively prevent rollover caused by the shift of the center of gravity during movement.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] This type of two-wheeled road transport trailer features multiple second mounting posts and two first mounting posts. Each of the two first mounting posts contains a fixed post, and both fixed posts have U-shaped forks at their upper ends. In use, after adjusting the position of the U-shaped forks, a jack is used to lift the front of the vehicle to be towed. The U-shaped forks are then inserted under the vehicle, and the front axle is engaged with the U-shaped forks to tow the vehicle. Because the fixed posts slide inside the first mounting posts, they can be pulled out and then inserted into two of the second mounting posts depending on the vehicle. This allows for adjusting the distance between the fixed posts and the U-shaped forks, making it suitable for towing vehicles of different sizes. The adjustment process is simple, improving towing efficiency. The mounting posts also have markings on their surface, allowing for easy adjustment of the U-shaped fork spacing.
