Baby walker speed reducing mechanism

The utility model discloses a speed reducing mechanism of a baby walker, which relates to the technical field of baby walkers and comprises a first speed reducing mechanism used for being connected to wheels of the baby walker, a second speed reducing mechanism used for being connected to a baby walker main body and a speed regulating mechanism acting between the first speed reducing mechanism and the second speed reducing mechanism. A transmission connecting part is formed at the inner end of the first speed reducing mechanism, and a transmission piece is formed on the surface of the transmission connecting part; a reinforcing cavity is formed in the first speed reducing mechanism and located in at least one part of the area of the transmission connecting part, and a reinforcing pin is arranged in the reinforcing cavity. The reinforcing pin is arranged in the reinforcing cavity, so that the overall strength of the first speed reducing mechanism is improved, and the service life of the speed reducing mechanis
