Schoolbag rods belong to a class of aluminum alloy rods

The obvious style of the aluminum alloy rod is the schoolbag rod, so its matching material is different from other rod matching materials. Because the ultra-light levers of schoolbags are used by many elementary school students now, they have become an artifact for them to reduce the burden of schoolbags, making it easier to go to and from school. Like the two-wheeled schoolbag trolley style, its own weight is much lighter than the four-wheel and six-wheel.

Will there be any connection between the luggage trolley and the bag trolley?

What are the points of communication between the luggage cart and the schoolbag lever? The first is the similarity of appearance and structure.
