In use, the reinforcing strip 102 is fixed to the ground, and then the second inclined plate 203 is flipped to the lower side of the first inclined plate 201, so that the second inclined plate 203 and the first inclined plate 201 are on the same inclined plane. At this time, the lower edge of the second inclined plate 203 is in contact with the ground. Then, the car is driven on the lifting plate 5 through the second inclined plate 203 and the first inclined plate 201. After the car is removed from the ramp support, the second inclined plate 203 is flipped towards the first inclined plate 201, thereby reducing the area occupied by the entire ramp support and effectively ensuring the use effect of the ramp support.
