[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] Example: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a size-adjustable packaging box, including a top plate 1, a side plate 3, and a bottom plate 5; The rear end of the base plate 5 is connected to the rear plate 6, the rear plate 6 is connected to the auxiliary rear plate A601, the rear side of the auxiliary rear plate A601 is connected to the auxiliary rear plate B602, the top plate 1 is placed on the upper end of the base plate 5, the rear side of the top plate 1 is connected to the auxiliary top plate A101, the rear side of the auxiliary top plate A101 is connected to the auxiliary top plate B102, and the auxiliary top plate B102 is connected to the auxiliary rear plate B602. The two sets of side plates 3 are placed on the left and right sides of the base plate 5 respectively, and are connected to the left and right sides of the base plate 5 respectively.

[0020] Among them, such as Figure 3 and Figure 4 As shown, each of the two sets of side panels 3 has a secondary side panel A301 connected to its rear side, and a secondary side panel B302 connected to the rear side of secondary side panel A301. A secondary side panel C303 is connected to the rear side of secondary side panel B302. Each of the two sets of side panels 3 has a secondary side panel D304 connected to its front end. By folding the secondary side panels A301, B302, and C303 on the rear side of the side panels 3, the lateral width of the packaging box is changed to accommodate items of different widths. After folding, secondary side panel D304 connects to the inner surface of the positioning plate 4, increasing the stability of the packaging box.

[0021] Among them, such as Figure 2 and Figure 4 As shown, the front of the top plate 1 is connected to the front plate 2, and the front plate 2 is connected to the auxiliary front plate A201. The auxiliary front plate A201 is connected to the auxiliary front plate B202. A set of box magnets 1 203 are installed on the left and right ends of the auxiliary front plate B202 respectively. The auxiliary front plate A201 and the auxiliary front plate B202 form a multi-layer movable connection structure, which makes it easy to ensure the flexible connection between the box magnets 1 203 and the box magnets 2 7 without changing the height when the horizontal dimension of the packaging box changes.
