When the bottom plate 220 flips from the vertical state to the inclined state, The second gear lever 240 is away from the first gear lever 130, and the second gear lever 240 is lowered, and the spare tire 3 is lowered. The firefighter standing on the side of the fire truck can take out the spare tire 3 in the second placement point 210 without climbing up. The use of this vehicle-mounted spare tire carrying device can achieve fixed carrying of the spare tire 3. When the spare tire 3 needs to be replaced, the firefighter does not need to go to the roof to remove the spare tire 3, which greatly reduces the operational risk. The spare tire 3 can be removed from the vehicle or put back by one person, which is simple and labor-saving, and improves the efficiency of replacing the spare tire 3.
[0038] The vehicle-mounted spare tire carrying device provided by the utility model has the following beneficial effects:
