[0027] Embodiment 2

[0028] A rear bracket for a breakdown vehicle, the outer walls of the ends of the first support plate 5 and the second support plate 7 away from the load-bearing rod 1 are both sleeved with support tubes 9, the two groups of support tubes 9 are respectively slidably connected to the outer walls of the first support plate 5 and the second support plate 7, a fixing groove 10 is opened on the upper surface of the support tube 9, the fixing groove 10 abuts against the outer wall of the tire, adjusting holes 11 are opened on one side of the support tube 9, the second support plate 7 and the auxiliary connecting plate 6, and fixing bolts 12 are inserted into the adjusting holes 11.

[0029] In this embodiment, specifically: the second support plate 7 is parallel to the first support plate 5, and multiple groups of adjustment holes 11 are provided, and the multiple groups of adjustment holes 11 are evenly distributed;

[0030] Among them, the multiple groups of adjustment holes 11 enable the staff to adjust the distance between the fixed slots 10 on both sides of the load-bearing rod 1 according to the tire spacing, so that the rear bracket of the breakdown vehicle can tow vehicles of different models.

[0031] In this embodiment, specifically: a connecting shaft 13 is provided at one end of the load-bearing rod 1 away from the second hinge block 4, a traction plate 14 is provided at the bottom end of the connecting shaft 13, and the traction plate 14 is connected to the breakdown vehicle;

[0032] Among them, the two sets of fixed slots 10 on the same side of the load-bearing rod 1 are close to each other, the fixed slots 10 are inclined towards the tires of the vehicle to be towed, the electric hydraulic rod 8 is electrically connected to an external power source, the electric hydraulic rod 8 adopted in this application is a prior art, and the connection between the electric hydraulic rod 8 and each component is also a prior art.
