[0002] The packaging box is an important part of the product. On today's dazzling shopping mall shelves, what first catches people's eyes is often the packaging box of the product. The packaging box plays a very important role in the sales of the product. Especially its role in attracting consumers, increasing the added value of the product, meeting the spiritual needs of consumers, and consolidating the brand and corporate image is increasingly recognized by people.

[0003] For example, a microphone packaging box disclosed in Chinese Utility Model CN214608581U includes a box body and a cover body covering the box body. The box body includes a storage part. The cover body includes a first cover plate and a second cover plate. One side of the first cover plate is connected to the boundary of the storage part, and one side of the second cover plate is also connected to the boundary of the storage part. The first cover body and the second cover body are oppositely arranged on the storage part.

That is to say, when the first fixing plate 121 is folded and rotated relative to the top cover 12, the substrate 13 can be synchronously driven to rotate so that the substrate 13 abuts against the bottom plate 111 and stands up to form the structure of the microphone holder 20.

[0043] Specifically, a first pulling plate 123 is provided at the end of the first fixing plate 121 facing away from the top cover 12, and second insertion plates 124 are provided on the left and right sides of the first pulling plate 123. The second insertion plates 124 on the left and right sides can be inserted into the left and right insertion interfaces 1125 at the front side correspondingly. With such a structure, when in the state of the microphone packaging box 10, the user can directly pull the first pulling plate 123 to act on the top cover 12 to rotate counterclockwise and fold backward, and act on the substrate 13 to rotate counterclockwise and fold forward to obtain the structure of the microphone holder 20; during the process of opening the microphone packaging box 10, the microphone installed inside can be displayed at different angles, making the opening method more ceremonial; at the same time, it can be used as a support structure for displaying the microphone, enriching the function of the microphone packaging box 10 and allowing the user to reuse it repeatedly.

[0044] More specifically, the support seat body includes a first seat body 131 and a second seat body 132. The second seat body 132 and the first seat body 131 are integrally formed at a front and rear distance on the side surface of the substrate 13 facing away from the top cover 12; the first seat body 131 is provided with a first support through hole 1311 penetrating its front and rear surfaces, and the second seat body 132 is provided with a first support blind hole 1321 penetrating its rear surface; when the top cover 12 and the substrate 13 are folded into the microphone holder 20, the second seat body 132 can abut against the bottom plate 111. During the process of loading the microphone, first insert the bottom of the microphone through the first support through hole 1311, and then continue to move the microphone until the bottom of the microphone is inserted into the first support blind hole 1321, and the installation operation of the microphone can be completed.

[0045] Please also read Figures 2 to 4 Preferably, after the top cover 12 and the base plate 13 are folded into the microphone stand 20, the top cover 12, the base plate 13 and the bottom plate 111 are arranged in a triangle, and the base plate 13 and the bottom plate 111 form a first angle a1, which is between 1 degree and 177 degrees. For example, the second seat body 132 is placed against the front end of the first accommodating cavity 116, so that the first angle between the base plate 13 and the bottom plate 111 is 110 degrees, so that the microphone can be displayed tilted; or the base plate 13 is perpendicular to the bottom plate 111, so that the first angle between the base plate 13 and the bottom plate 111 is 90 degrees, so that the microphone can be displayed vertically; or the first angle between the base plate 13 and the bottom plate 111 is set to 177 degrees, so that the microphone can be displayed nearly flat.
