The support part supports the baby shelf. The occupant can put the baby on the baby shelf and hug the baby with one hand. Therefore, the hand can be free to operate the buttons, and the support part can be grasped and supported during the ride, which effectively avoids A fall occurs during the ride, which improves the safety of riding the elevator. In addition, when the baby shelf is not needed, the baby shelf can also be accommodated in the shelf slot, thereby saving riding space, and when the baby shelf is stowed, the support part can also be used by the occupant to grasp and support; During operation, pull the handle to make the stop rod retract into the transverse slide groove. At this time, the stop rod releases the blocking of the first sliding block, and the first sliding block will drive the lifting rod upward under the elastic restoring force of the first return spring. The lifting rod drives the rack to go up. When the rack goes up, it will drive the second gear to rotate in a clockwise direction. The second gear will drive the first gear and the baby shelf to rotate counterclockwise until the baby shelf rotates to a vertical position. In the state, the folding of the baby shelf is completed, and finally the handle is released, so that the blocking lever is reset under the elastic restoring force of the second return spring.
