When in use, the hose is stored in the accommodating cavity of the vehicle body, and is transported and laid through the front wheel body and the rear wheel body, which greatly reduces the labor intensity of firefighters. At this time, the folding mechanism flips the belt reel rod to be parallel to the radial direction of the rear wheel body to avoid the belt reel rod hindering transportation and laying. When the fire fighting is over, the vehicle body is inverted so that the rear wheel body is located at the top, and the folding mechanism flips the belt reel rod to be parallel to the axial direction of the rear wheel body. The hose is placed in the gap between the two belt reel rods. The rear wheel body can be turned to quickly roll up the hose. There is no need to carry an additional belt reel device, which is more convenient to use, greatly reducing the labor intensity of firefighters and improving firefighting efficiency. The diameter of the rear wheel body is larger than the diameter of the front wheel body, and the height of the upper end of the rear wheel body is higher than 1 / 2 of the height of the vehicle body, so as to facilitate belt reeling, and the rear wheel body is directly larger than the belt roll diameter after belt reeling.
