The utility model relates to the technical field of tire fixing devices, in particular to an adjustable tire fixing device which comprises a first supporting frame, a second supporting frame and a transverse connecting
assembly, the first supporting frame and the second supporting frame are adjustably connected to the two ends of the transverse connecting
assembly, and the transverse connecting
assembly comprises an angle iron piece and a connecting plate. A plurality of connecting holes are formed in the ends, close to each other, of the angle iron piece and the connecting plate, the connecting holes are distributed in the length direction of the angle iron piece or the connecting plate, and the angle iron piece and the connecting plate are connected with the connecting piece in a matched mode through a certain connecting hole. The tire fixing device solves the problems that a traditional tire fixing device is poor in compatibility, tedious in operation, prone to loosening and the like, the size-adjustable structure is adopted, the tire fixing device can adapt to various vehicle types, tools do not need to be replaced, one
machine has multiple purposes, and the
purchase cost of a user is reduced. The
system is suitable for logistics transportation, maintenance workshops, field camping and other scenes. And the operation efficiency and the user experience are improved through the quick mounting and dismounting structure.
