[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-3 The packaging box shown includes a base 1 and a box body 2. The base 1 provides support for the box body 2 and allows the lid 3 to be folded and flipped on it. The lid 3 is fixedly connected to the top of the base 1, which facilitates the placement of items. The box body 2 is fixedly connected to the top of the base 1.

[0025] Furthermore, the interior of the box 2 is equipped with a limiting mechanism 4 for positioning items. The limiting mechanism 4 includes a limiting plate 41, a guide plate 42, and an adjusting column 44. The limiting plate 41 facilitates the placement of items and promotes the movement of the buffer plate 43. The limiting plate 41 also helps to clamp and limit the items, preventing them from sliding freely and increasing the stability of the placement. The guide plate 42 provides horizontal guidance for the sliding of the limiting plate 41 and facilitates its installation and removal. The adjusting column 44 locks the position of the limiting plate 41, allowing for position adjustment to accommodate items of different sizes. The guide plate 42 is fitted against the inner wall of the box 2, and the limiting plate 41 is slidably mounted on the guide plate 42. 1. Used for clamping and positioning items. Adjusting column 44 is slidably set on limiting plate 41. Limiting grooves that cooperate with adjusting column 44 are equidistantly opened at the bottom of inner wall of box 2. Assembly plate is symmetrically fixedly connected to the top of guide plate 42. Assembly plate and assembly bolt facilitate the installation and disassembly of guide plate 42 and limiting plate 41, which is convenient for use according to needs. Assembly bolt is threadedly connected to the side of assembly plate. One end of assembly bolt is threadedly connected to inner wall of box 2. Guide groove is opened on the side of limiting plate 41. Guide plate 42 is slidably connected to the inner cavity of guide groove. Buffer plate 43 is fixedly connected to the side of limiting plate 41. Buffer plate 43 is made of rubber and has a certain deformation, which is beneficial for clamping and protecting items.

[0026] More specifically, the top of the limiting plate 41 has a square groove, and a traction frame 45 is installed inside the square groove. The traction frame 45 is convex in shape, which facilitates the movement of the adjusting column 44 and allows for traction operations on the adjusting column 44, causing it to disengage from the inner cavity of the limiting groove. The bottom of the traction frame 45 is fixedly connected to the adjusting column 44. The bottom end of the inner wall of the square groove has a first sliding groove symmetrically provided to cooperate with the adjusting column 44, and a second sliding groove is provided at the bottom end of the inner wall of the square groove. The inner cavity of the second sliding groove is provided with a bearing plate 46, which facilitates the vertical guidance of the sliding of the round rod and also facilitates the compression of the spring 48. The top of the bearing plate 46 is symmetrically fixedly connected with a square plate. The square plate and the positioning bolts facilitate the installation and removal of the bearing plate 46 to install and remove the spring 48. The side threads of the square plate are inserted. A positioning bolt is connected, with one end of the positioning bolt threadedly inserted into the inner wall of the second slide groove. A linkage plate 47 is fixedly connected between adjacent adjusting columns 44, which facilitates the simultaneous movement of the adjusting columns 44 and allows for simultaneous operation of two adjacent adjusting columns 44. The linkage plate 47 is slidably inserted into the inner cavity of the second slide groove. A round rod is symmetrically fixedly connected to the top of the linkage plate 47, which helps guide the deformation of the spring 48. The outer wall of the round rod is slidably inserted into the bearing plate 46. A spring 48 is sleeved on the outside of the round rod. The elastic force of the spring 48 helps to push the linkage plate 47 to move, making it easy for the linkage plate 47 and the adjusting column 44 to return to their original positions after movement, and facilitating repeated operation of the adjusting column 44. One end of the spring 48 is in contact with the bearing plate 46, and the other end of the spring 48 is in contact with the inner wall of the second slide groove.
