Problems solved by technology

[0002] The shoulder strap holes of traditional child safety seats are all fixed. When adjusting the seat straps, you have to remove the shoulder straps from the original shoulder strap holes and then insert them into another row of shoulder strap holes. The operation is cumbersome and time-consuming.
Now, the shoulder belt of the child safety seat is adjusted together with the lifting of the headrest. The adjustment of the headrest is mainly based on the oblique structure of the pull rod. Reliable and adjustable, its transmission structure is complicated, there are many parts, the production cost is high, the spring is difficult to cooperate and assemble, and there are hidden dangers in the stability and service life of the spring
