More optimally, as shown in fig. 2 and 4, in the advancing process of the vehicle body 100, the vehicle body 100 can rock due to the reason that the road surface is uneven or particles such as stones exist on the road surface, and meanwhile, the roadblocks are formed by orderly stacking a plurality of roadblocks in sequence, and when the vehicle body 100 rocks, the roadblocks placed in the mounting holes can rock together, so that the roadblocks can topple over, and for solving the problem, the upper end face of the mounting plate 140 is provided with a blocking component.
