The existing bottom-hung spare tire dismounting process and device have the following shortcomings: 1) the spare tire tool taking and placing process is time-consuming and laborious. The spare tire tool of part SUV models or pick-up truck models is placed below the trunk cover plate, and all the articles in the trunk need to be taken out before the spare tire tool is taken. When the articles in the trunk are more or heavier, it is very inconvenient to take and place and the taking and placing time is relatively long. 2) the assembly mode of the spare tire tool is relatively complex. The spare tire tool usually includes a force wrench, a force rod and an extension rod, which need to be manually installed, and the installation direction of the force wrench has a clear requirement. The whole assembly process is not very friendly to the drivers who have not operated the spare tire tool and female drivers. 3) the manual rotation of the spare tire tool to drive the lifter assembly process is time-consuming and laborious, and the assembled force rod needs to be placed in the tire unloading space of the driving lifter assembly, and rotated with force until the spare tire is completely unloaded. The rotating force is about 30NM (not the same for different models), and the time is about 4 minutes. Female drivers operate more laboriously, and it is more laborious in special environments such as highland areas. CONTENT OF THE UTILITY MODEL
