In the initial state, the adjusting plate 12 is away from the fixed plate 11. When the adjusting plate 12 approaches the fixed plate 11, the adjusting plate 12 and the fixed plate 11 drive the swing arm 15 to rotate close to each other, and the swing arm 15 drives the support arm 16 and the tug rod 22 to extend outward, thereby controlling the ground clearance of the tug rod 22. The telescopic amount of the tug rod 22 is adjusted according to the depth of the tire sinking, and the telescopic amount of the tug rod 22 is maintained at a reasonable level. When the wheel hub drives the tug rod 22 to rotate upward, the next tug rod 22 contacts the ground, and the tug rod 22 is connected to the fixed shaft 29 and the foot support body. 33 drives the auxiliary escape foot 25 to contact the road surface, and the auxiliary escape foot 25 plays a supporting role. When the auxiliary escape foot 25 is opened outward, the road soil contacts the supporting paddles 24 on the upper side of the auxiliary escape foot 25. The function of the supporting paddles 24 is to increase the supporting surface of the auxiliary escape foot 25, which is suitable for muddy roads. When the wheel hub drives the tugboat rod 22 to rotate upward and leave the ground, the auxiliary escape foot 25 contracts inward, folds the supporting paddles 24, reduces the cross-sectional area of ​​the auxiliary escape foot 25, and facilitates the auxiliary escape foot 25 to be pulled out of the mud.
