Specifically, Figure 7 and Figure 8 As shown, according to an embodiment of the present application, two edges of the bottom of the box body 6 facing each other may have mounting blocks 15, and correspondingly, corresponding positions on the platform 1 may have mounting grooves 8, and the mounting blocks 15 at the bottom of the box body 6 may be installed in the mounting grooves 8 on the platform 1 to achieve detachable installation of the box body 6 and the platform 1. Specifically, as Figure 8 As shown, the end of the installation groove 8 is larger in size for the installation block 15 to enter, and the size of other parts of the installation groove 8 is smaller than the end. After the installation block 15 enters from the end, it slides to other parts to achieve snap-on limiting.
