Abstract
A locking gear of kid handcarts comprises a first bar, a second bar connected to the first bar by a rotation pivot. The second bar is provided with a sliding part and the middle of the first bar and the sliding part is provided with a first locking gear. The first locking gear has two working position of locked up and unlocked. When the sliding part sleeks along the direction of the second bar and makes the relative position of the two change, the first locking gear converts from the working position of locked up to the working position of unlocked. The middle of the second bar and the sliding part is provided with a second locking gear. The second locking gear has the working position of locked up and unlocked. Only the second locking gear is in the working position of unlocked the first locking gear can be unlocked, that's to say the wheelbarrow of children need twice unlocking control to be folded. This can play the effect of insurance, and do well to the safety of children on the wheelbarrow of children.
