[0018] When using the product, if it is necessary to package products of different sizes and shapes, first place the inner liner box 3 in the placement slot 2 of the box body 1. If the products need to be placed separately, according to the quantity and size of the products, insert the first insert plate 601 into the first slots 401 at both ends of the first storage cavity 4. Then, insert multiple second insert plates 602 into the corresponding second slots 402 on both sides of the first storage cavity 4. By adjusting the number and position of the second insert plates 602, the first insert plate 601 and the second insert plate 602 are vertically engaged, thus dividing the first storage cavity 4 into multiple relatively independent placement areas that conform to the product size. This allows for flexible adjustment of the internal space of the packaging box to accommodate different products.

[0019] This utility model also includes that the cover plate 8 is a horizontally arranged rectangular plate structure, and a pull strip 802 is provided between the two tear lines 801.

[0020] The present invention also includes that the first storage cavity 4 has a first slot 401 at both ends, the first insert plate 601 is inserted into the first slot 401 at both ends, and multiple sets of oppositely arranged second slots 402 are provided on both sides of the first storage cavity 4.

[0021] The present invention also includes that multiple second insert plates 602 are arranged in parallel with each other, and both ends of the second insert plates 602 are inserted into the second slots 402, and the first insert plate 601 is perpendicularly engaged with the second insert plate 602.
