[0002] In the current tractor manufacturing enterprises, after the manufacture of the tractor is completed, it needs to be shipped to the sales site, but because the tractor is relatively large in size, it is generally not transported to the sales site by transport tools, but is transported by self-driving. The newly shipped tractor is not combined with the semitrailer, and the two sides of the vehicle frame are generally full of components such as tire mudguards, fuel tanks, and starting batteries, and there is no space to place the spare tire frame. In the process of sending the vehicle to the sales site, a rope is generally temporarily bound on the vehicle frame, and because there is no special spare tire fixing frame on the vehicle frame, the fixing is often not very firm, and some manufacturers temporarily fasten the spare tire on the vehicle frame or the tractor saddle by using a bent hook and fasteners, but it is difficult to reliably fix the spare tire by using the bent hook, and the spare tire is prone to displacement during transportation due to jolting, and even accidents may occur due to insecure fixing of the spare tire during transportation, which poses a certain safety hazard.
