A fifth fold line is provided between the upper cover plate and the rear plate, and a second assembly opening is provided on the fifth fold line. The lower bottom plate is folded upward along the second fold line between the lower bottom plate and the rear plate. Then, the stop plate extending from the other side of the lower bottom plate relative to the rear plate is folded inward along the third fold line between the lower bottom plate and the stop plate, so that the stop plate can be located opposite the rear plate. (A04) The inner cover plate extending from the other side of the stop plate relative to the lower bottom plate is folded inward along the fourth fold line between the stop plate and the inner cover plate. The first fixing protrusion of the inner cover plate protruding from the other side of the stop plate is inserted into the second assembly opening on the fifth fold line corresponding to the upper cover plate, thereby forming a positioning. (A05) Fold the upper cover plate inward along the fifth fold line to fit it against the surface of the inner cover plate. Then, fold the positioning plate extending from the other side of the upper cover plate relative to the rear plate upward along the sixth fold line between the upper cover plate and the positioning plate to align the fixing opening at the center of the positioning plate with the stop plate. At this time, fold the side plates extending from the two sides of the positioning plate inward along the seventh fold line between the positioning plate and the two side plates to insert the second fixing protrusions on the other side of each side plate into the first assembly openings at the first fold line corresponding to the two support plates to form a fixation. (A06) Fold the positioning plate with a wider positioning base plate extending from one side upward along the ninth fold line between the positioning plate and the positioning base plate to align the positioning base plate horizontally with the lower base plate. (A07) The positioning device is inserted into the receiving space of the main body through an opening on one side of the trapezoidal main body, and the positioning base plate of the positioning device is slightly smaller than the bottom plate of the main body, so that the two sides of the positioning base plate can abut against the inner wall surface of the main body; (A08) The preset storage item to be placed is inserted into the positioning device through the fixing opening of the positioning plate and held against the surface of the stop plate, thereby fixing it inside the positioning device; (A09) The lid of the main body of the box with the opening is closed upwards to complete the assembly of the present invention.

6. The assembly method of the gold brick packaging box as described in claim 5, wherein in step (A04), the remaining two opposite sides of the stop plate each have an extended side plate, and the side plate is folded inward along the second inward fold line between the side plate and the stop plate, so that the two side plates can be aligned with the inner wall surface of the two side plates when the two side plates are assembled, thereby relying on the two side plates to provide support for the stop plate, so as to prevent excessive deformation when the preset storage object abuts against the stop plate.

7. The assembly method of the gold brick packaging box as described in claim 5, wherein in step (A05), an eighth fold line is provided between the two second fixing protrusions and the two side plates of the positioning device, which can provide the two second fixing protrusions with greater flexibility in bending by the eighth fold line, and facilitates the fixing of the second fixing protrusions.
