[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0014] 1. The first storage box and the second storage box are rotated by external force, while the hinge is between the first storage box and the second storage box and has a connecting function, so as to ensure that the first storage box and the second storage box can maintain a horizontal position after the rotation is completed, and then when one side of the first storage box contacts one side of the second storage box, the card block is driven by the second storage box to contact one side of the first storage box, and at the same time, the inclined surfaces of the limit blocks on both sides contact the inclined surfaces on both sides of the card block, and then continue to apply pressure to the second storage box, so that the squeezing of the card block causes the limit blocks on both sides to slide, and when the second storage box and the first storage box maintain a horizontal position, the card block fits with the card slot, and at the same time, the limit block limits and fixes the sliding card block, thereby realizing and improving assembly efficiency.

[0015] When the first storage box is in a horizontal position and needs to be fixed, the inclined surfaces on both sides of the card block will fit with the inclined surfaces of the limit block, and then continue to apply pressure to the card block, so that the limit block slides in the second sliding groove, and then the limit block slides to drive the limit post to slide, and the first spring contracts at the same time. When the card block abuts against the limit sliding block, the first spring will drive the limit block to slide through its own force, so that the limit block abuts in the square card slot, thereby fixing the first storage box to prevent loosening during movement. When contact limit fixation is required, pressure is applied to the pressing post so that the pressing post slides to drive the fixed block to slide, and then the fixed block slides to drive the limit sliding block to slide, thereby releasing the limit fixation of the card block, thereby achieving and improving usability.
