A connecting rod 4 is slidably connected to the inner wall of the sliding groove 8. A mating wheel 5 is fixedly connected to the lower surface of the connecting rod 4. A first positioning hole 6 is opened on the surface of the connecting rod 4, and a second positioning hole 7 is opened on the surface of the connecting rod 4 below the first positioning hole 6. A mating hole 9 is opened on the surface of the support frame 3. One end of the mating hole 9 penetrates the front and back surfaces of the support frame 3. A fixing bolt 10 is provided in the mating hole 9. A limit plate 11 is fixedly connected to the top of the connecting rod 4. The inner wall of the sliding groove 8 is slidably connected to the limit plate 11. When the device is used for road compaction, the fixing bolt 10 is removed from the mating hole 9, and then the connecting rod 4 is lifted upwards, causing the connecting rod 4 to slide with the sliding groove 8, thereby making the second positioning hole 7 coincide with the mating hole 9. Then, one end of the fixing bolt 10 is passed through the mating hole 9 and the second positioning hole 7, and the nut is tightened on the fixing bolt 10, so that the mating wheel 5 leaves the ground. The road roller 2 is used to flatten the ground. When the device is moved, the fixing bolt 10 is removed first, and the connecting rod 4 is pushed downwards, so that the mating wheel 5 is in contact with the ground. At the same time, the first positioning hole 6 coincides with the mating hole 9. The position of the mating wheel 5 is fixed by the fixing bolt 10. When the device is moved, the mating wheel 5 shares the pressure, so that the road surface is not easily damaged.
