3 Product classification
3.1 Varieties
3.1.1 According to the different structures, it can be divided into two types: integral type (the wheel body and the box are connected by fixings), as shown in Figures 1 and 2; detachable type (the wheel body is not connected by fixings, but is directly inserted into the base and connected to the box body), as shown in Figures 3 and 4. 3.1.2 According to the different types, it can be divided into two types: directional type, as shown in Figures 1 and 3; steering type, as shown in Figures 2 and 4.
