Problems solved by technology

[0003] During the folding process of the above baby stroller, as long as a downward force is given to the push handle bar, the front end of the push handle bar will drive the front end of the rear wheel bracket to When the front and bottom move, the sliding sleeve will also slide to the rear end of the rear wheel bracket under the action of the connecting rod, so that the size of the vehicle can be reduced in the up and down direction after folding. Although this folding method is very convenient to operate, the overall After the car is folded, the size in the front and rear directions cannot be reduced, so there is still the problem of large volume after folding, and the packaging volume cannot be fundamentally reduced
