Abstract
Provided is a stroller. A stroller rack comprises a front wheel support, a back wheel support, an adjusting frame, a push rod frame and a back sliding piece, wherein the upper portion of the back wheel support and the upper portion of the front wheel support are in rotating connection around a first shaft, and the lower portion of the push rod frame and the back wheel support are in rotating connection around a fourth shaft. The back sliding piece can only be arranged on the push rod frame in a sliding mode in the length direction of the push rod frame up and down. The adjusting frame and the back wheel support are in rotating connection around a second shaft. The front portion of the adjusting frame can slide in the length direction of the front wheel support up and down and be arranged on the front wheel support around a third shaft in a rotating mode, and the back portion of the adjusting frame is arranged on the back sliding piece around a fifth shaft in a rotating mode. The second shaft is arranged below the first shaft and placed above the fourth shaft.
