Trundle double-pedal linkage structure

The utility model relates to the technical field of mechanical equipment, and particularly discloses a trundle double-pedal linkage structure which comprises a support assembly, wheel pieces, a linkage brake assembly, a brake assembly and a brake release assembly. The support assembly is provided with a first rotating shaft and a second rotating shaft, and the wheel pieces are arranged at the two ends of the support assembly through the first rotating shaft; the linkage brake assembly is arranged on the support assembly, the brake assembly is rotationally arranged on the support assembly through a first rotating shaft, the brake assembly acts on the linkage brake assembly so that the linkage brake assembly can be meshed with the wheel sheet to enter a brake state, and the brake release assembly is rotationally arranged on the support assembly through a second rotating shaft and is in meshed connection with the brake assembly. And the brake releasing assembly acts on the brake assembly, so that the linkage bra
