[0031] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0033] Please see Figure 1 and Figure 2 The cutter assembly 1000 includes a first cutter 1 and a second cutter 2. The first cutter 1 is used to interlock and engage with the second cutter 2. The first cutter 1 and the second cutter 2 together enclose a first limiting space A, which is used to limit the movement of accessories housed in the packaging box. The engaging engagement of the first cutter 1 and the second cutter 2 allows for the containment and limiting of the accessories, preventing unexpected displacement due to external forces during transportation. Furthermore, the engaging structure of the first cutter 1 and the second cutter 2 facilitates quick and easy disassembly of the cutter assembly 1000, improving the user's comfort in handling accessories and facilitating recycling, thereby increasing the resource utilization rate of the cutter assembly 1000.

[0034] It is understood that the materials of the card-splitter assembly 1000 include, but are not limited to, plastic, cardboard, rubber, metal plate, etc. For example, in this embodiment, the material of the card-splitter assembly 1000 is cardboard.

[0035] It is understandable that the locking structure of the first card 1 and the second card 2 includes, but is not limited to: card hook and card slot, card slot and card, card slot and card slot, or card slot and card claw, etc.

[0036] For example, in this embodiment, a slot-to-slot mating structure is used. For details, please refer to [the relevant documentation / reference]. Figure 3 and Figure 4 The first blade holder 1 includes a first body 11 and a plurality of first locking portions 12 extending from the first body 11, with a first locking groove 13 formed between any two adjacent first locking portions 12; the second blade holder 2 includes a second body 21 and a plurality of second locking portions 22 extending from the second body 21, with a second locking groove 23 formed between any two adjacent second locking portions 22; the first locking groove 13 is used for engaging the second body 21, and the second locking groove 23 is used for engaging the first body 11. Furthermore, the engaging directions of the first locking groove 13 and the second locking groove 23 are opposite, so that while the first locking groove 13 engages the second body 21, the first body 11 is engaged within the second locking groove 23, ensuring a stable connection between the first blade holder 1 and the second blade holder 2.

[0037] Furthermore, the depth of the first slot 13 is the same as the height of the second body 21, and the depth of the second slot 23 is the same as the height of the first body 11, so that the surfaces of the first blade card 1 and the second blade card 2 after being engaged are flush, which facilitates the stacking of the multi-layer blade card assembly 1000.

[0038] For example, in this embodiment, the depth of the first card slot 13 and the second card slot 23 is 64mm, and the height of the first body 11 and the second body 21 is 64mm.

[0039] Furthermore, a first inclined portion 121 is provided on one side of the end of the opening of the first slot 13 of the first locking part 12, and a second inclined portion 122 is provided on the other side of the end of the opening of the first slot 13 of the first locking part 12. The first inclined portion 121 of one first locking part 12 and the second inclined portion 122 of the other first locking part 12 together form a trumpet-shaped first guide groove 14. The trumpet-shaped first guide groove 14 is connected to the first slot 13. The first guide groove 14 is used to guide the second body 21 into the first slot 13. The trumpet-shaped first guide groove 14 makes the opening of the first guide groove 14 linearly shrink from large to small during the process of the second body 21 being inserted into the first slot 13. The insertion of the second body 21 does not require manual precision positioning. It is only necessary to insert the second body 21 into the first guide groove 14, and the inclined side wall of the first guide groove 14 can guide the second body 21 during installation.

[0040] Understandably, the width and depth of the first guide groove 14 are determined based on actual needs and in combination with the width of the first slot 13. This embodiment will not provide specific examples.

[0041] For further details, please refer to Figure 3 and Figure 4 In some embodiments, the second locking part 22 has a third inclined part 221 on one side of the end of the slot of the second locking groove 23, and a fourth inclined part 222 on the other side of the end of the slot of the second locking part 22. The third inclined part 221 of one second locking part 22 and the fourth inclined part 222 of the other second locking part 22 together form a trumpet-shaped second guide groove 24. The trumpet-shaped second guide groove 24 is connected to the second locking groove 23 and is used to guide the first body 11 into the second locking groove 23. The trumpet-shaped second guide groove 24 causes the slot of the second guide groove 24 to linearly decrease in size from large to small during the process of the first body 11 being inserted into the second locking groove 23. The insertion of the first body 11 does not require manual precision positioning; it is only necessary to insert the first body 11 into the second guide groove 24, and the inclined sidewall of the second guide groove 24 can guide the first body 11 during installation.

[0042] In some embodiments, please refer to Figure 3At least one first locking portion 12 is provided with a first groove 123, which is used to receive the limiting portion of the pad layer B to limit the pad layer B; and / or, at least one second locking portion 22 is provided with a second groove 223, which is used to receive the limiting portion of the pad layer B to limit the pad layer B. By receiving the limiting portion of the pad layer B with the first groove 123, the pad layer B is limited along the second direction Y, and / or, by receiving the limiting portion of the pad layer B with the second groove 223, the pad layer B is limited along the first direction X. Thus, the pad layer B is limited along the first direction X or the second direction Y, or both the first direction X and the second direction Y, so that the pad layer B will not be displaced unexpectedly when it is placed on the blade holder assembly 1000, thereby ensuring the isolation of the accessories between different layers and between the card holder assemblies, and avoiding collisions between accessories of different layers during transportation, which could cause damage to the accessories.

[0043] For further details, please refer to Figure 3 In some embodiments, the bottom of the first groove 123 is provided with a first clearance groove 124 for a user's finger to insert; and / or, the bottom of the second groove 223 is provided with a second clearance groove 224 for a user's finger to insert. By providing the first clearance groove 124 or the second clearance groove 224, when the first limiting space A contains an accessory, the user's finger can smoothly pass through the first clearance groove 124 or the second clearance groove 224, thereby directly contacting the accessory and facilitating the user's removal of the accessory.

[0044] Understandably, to protect the components, the pad B should be made of a material with elastic deformation capabilities, such as sponge, rubber, or plastic. Therefore, when the multi-layer blade assembly 1000 is stacked, the pad B is compressed. The presence of the first clearance groove 124 and the second clearance groove 224 ensures that there is sufficient space to accommodate the compressed limiting part when the pad B is compressed, further enhancing the limiting effect on the pad B.

[0045] It should be noted that the number of the first cutter card 1 and the second cutter card 2 mentioned above are all positive integers greater than or equal to one. For example, when the number of the first cutter card 1 and the second cutter card 2 is one, when the cutter card assembly 1000 is installed in the packaging box, the first cutter card 1 and the second cutter card 2 divide the receiving cavity of the packaging box into multiple first limiting spaces A; when the number of the first cutter card 1 and the second cutter card 2 is multiple, the multiple first cutter card 1 are spaced apart along the first direction X, and the multiple second cutter card 2 are spaced apart along the second direction Y, and the multiple first cutter card 1 and the multiple second cutter card 2 together enclose multiple first limiting spaces A; the existence of multiple first limiting spaces A allows multiple accessories to be stored in the packaging box at the same time. The first direction X and the second direction Y are perpendicular.

[0046] Furthermore, the distance between multiple second cutter cards 2 or multiple first cutter cards 1 can be adjusted to form multiple first limiting spaces A of different sizes, so that accessories of different sizes can be accommodated in first limiting spaces A of different sizes.

[0047] Understandably, the distance between multiple first blade cards 1 is determined by the spacing between multiple second card slots 23, and the distance between multiple second blade cards 2 is determined by the spacing between multiple first card slots 13. Therefore, adjusting the distance between multiple first blade cards 1 is essentially adjusting the distance between multiple second card slots 23 or changing the insertion distance between multiple first blade cards 1; adjusting the distance between multiple second blade cards 2 is essentially adjusting the distance between multiple first card slots 13 or changing the insertion distance between multiple second blade cards 2.

[0048] For example, in this embodiment, the distance between any two adjacent first slots 13 is 52mm, and along the extending direction of the second blade 2, the distances between the multiple second slots 23 are 60mm, 180mm, 130mm, and 54mm, respectively. This allows the first blade 1 and the second blade 2 to engage to form multiple first limiting spaces A of different sizes.

[0049] In actual packaging and transportation processes, it is also necessary to transport small-sized machines or parts (such as power cords, small-volume machine bodies, etc.). Therefore, the aforementioned first limiting space A needs to be further divided to accommodate small-sized parts. In some embodiments, please refer to [the relevant documentation]. Figure 5 and Figure 6 The tool holder assembly 1000 also includes multiple third tool holders 3, which are spaced apart along the first direction X. The multiple third tool holders 3 intersect and engage with multiple second tool holders 2, and are arranged side-by-side with the first tool holders 1. The tool holder assembly 1000 also includes multiple fourth tool holders 4, which are spaced apart along the second direction Y and alternately arranged with the multiple second tool holders 2. The multiple fourth tool holders 4 and the multiple third tool holders 3 are cross-connected to divide a portion of the first limiting space A into multiple first cavities A1. The first cavities A1 are distributed side-by-side along the second direction Y. By alternating the arrangement of the fourth tool holders 4 and the second tool holders 2, the fourth tool holder 4 can further divide the first limiting space A within its area to form the first cavities A1. This allows small-sized parts to be contained within the first cavities A1 by the inner wall of the first cavities A1, thus preventing damage to the small-sized parts caused by shaking within the first limiting space A.

[0050] For further details, please refer to Figure 3 , Figure 5 and Figure 6The third cutter 3 includes a third body 31 and a plurality of third locking portions 32 extending from the third body 31, with a third locking groove 33 formed between any two adjacent third locking portions 32; the fourth cutter 4 includes a fourth body 41 and a plurality of fourth locking portions 42 extending from the fourth body 41, with a fourth locking groove 43 formed between any two adjacent fourth locking portions 42; the third locking groove 33 is used for engaging the second body 21 and the fourth body 41, and the fourth locking groove 43 is used for engaging the third body 31. Through the engagement of the third locking groove 33 with the second body 21 and the engagement between the third locking groove 33 and the fourth body 41, the first limiting space A is divided into a plurality of first cavities A1. Furthermore, the insertion directions of the third locking groove 33 and the fourth locking groove 43 are opposite, thereby ensuring that while the third locking groove 33 engages the second body 21 and the fourth body 41, the third body 31 is engaged within the fourth locking groove 43.

[0051] Furthermore, the depth of the third slot 33 is the same as the height of the second body 21 or the fourth body 41, and the depth of the fourth slot 43 is the same as the height of the third body 31, so that the surfaces of the third blade card 3 and the fourth blade card 4 are flush after they are engaged, which facilitates the stacking of the multi-layer blade card assembly 1000.

[0052] For example, in this embodiment, the depth of the third card slot 33 and the fourth card slot 43 is 64mm, and the height of the third body 31 and the fourth body 41 is 64mm.

[0053] It should be noted that the length of the fourth cutter card 4 is selected according to the actual number of first compartments A1 to be divided. For example, when only one set of first compartments A1 is needed along the second direction Y, the length of the fourth cutter card 4 should be ensured to be less than the length of the first limiting space A to be divided. In order to organize the layout of the accessories housed in the first limiting space A, in this embodiment, the third cutter card 3 and the fourth cutter card 4 are set at the edge area of ​​the multiple first limiting spaces A formed by the first cutter card 1 and the second cutter card 2. The specific dimensional parameters will not be described in detail in this embodiment.

[0054] Furthermore, the opening of the third slot 33 can also be provided with a third guide groove 34 similar to the first guide groove 14 or the second guide groove 24 mentioned above. Specifically, a fifth inclined portion 321 is provided on one side of the end of the opening of the third slot 33 of the third locking part 32, and a sixth inclined portion 322 is provided on the other side of the end of the opening of the third slot 33 of the third locking part 32. The fifth inclined portion 321 of one third locking part 32 and the sixth inclined portion 322 of the other third locking part 32 together form a trumpet-shaped third guide groove 34. The groove 34 is connected to the third slot 33. The third guide groove 34 is used to guide the second body 21 and the fourth body 41 into the third slot 33. The trumpet-shaped third guide groove 34 makes the groove opening linearly smaller from large to small during the process of the second body 21 and the fourth body 41 being inserted into the third slot 33. The insertion of the second body 21 and the fourth body 41 does not require manual to ensure precise positioning. It is only necessary to insert the second body 21 and the fourth body 41 into the third guide groove 34, and the inclined side wall of the third guide groove 34 can guide the second body 21 and the fourth body 41 during installation.

[0055] Furthermore, the fourth card slot 4 can also be provided with a fourth guide slot 44 similar to the first guide slot 14, the second guide slot 24 and the third guide slot 34 described above. The corresponding fourth card part 42 is also provided with a seventh inclined part 421 and an eighth inclined part 422 to form the fourth guide slot 44 described above. For the specific structure and function of the guide slot, please refer to the above embodiments by analogy. It will not be described in detail here.

[0056] It should be noted that the third cutter 3 may be provided with a corresponding third groove (not shown in the figure), and / or the fourth cutter 4 may also be provided with a corresponding fourth groove 423, so that the third groove and the fourth groove 423 can accommodate the limiting part of the pad B, thereby further strengthening the limiting of the pad B and ensuring that the pad B will not undergo unexpected displacement.

[0057] Furthermore, the bottom of the third groove may also be provided with a third clearance groove (not shown in the figure), and / or the bottom of the fourth groove 423 may also be provided with a fourth clearance groove 424, so as to facilitate the user's fingers to be inserted, thereby facilitating the user to remove small-volume parts located in the first cavity A1, improving the convenience of the user's picking and placing operation and enhancing the user's user experience.

[0058] It should be noted that, in order to further enhance the stability of the pad B placed between the multi-layer blade card assembly 1000, in some embodiments, any one or more of the first blade card 1, the second blade card 2, the third blade card 3, and the fourth blade card 4 may be provided with limiting grooves. Specifically, the first main body 11 is provided with a first limiting groove 111 on the side opposite to the first card part 12; the second main body 21 is provided with a second limiting groove 211 on the side opposite to the second card part 22; the third blade card 3 is provided with a third limiting groove on the side opposite to the third card part 32; and the fourth blade card 4 is provided with a fourth limiting groove 411 on the side opposite to the fourth card part 42.

[0059] Regarding the aforementioned padding layer B, it is understood that the structure that padding layer B can adopt includes, but is not limited to, the following: a thin plate-shaped padding layer, a strip-shaped padding layer, a column-shaped padding layer, etc.

[0060] For example, in this embodiment, the pad B is a strip-shaped pad B and there are multiple strip-shaped pads B. Further, along the third direction Z, the center line of the first limiting groove 111 coincides with the center line of the first groove 123, the center line of the second limiting groove 211 coincides with the center line of the second groove 223, the center line of the third limiting groove coincides with the center line of the third groove, and the center line of the fourth limiting groove 411 coincides with the center line of the fourth groove 423, so as to ensure that when multiple blade assemblies 1000 are stacked, a portion of the strip-shaped pad B is received in the first groove 123 of one blade assembly 1000, and another portion of the strip-shaped pad B is received in the first limiting groove 111 of another blade assembly 1000. A portion of the strip-shaped pad B is received in the second groove 223 of the two-blade clamping assembly 1000, and another portion of the strip-shaped pad B is received in the second limiting groove 211 of another clamping assembly 1000. Alternatively, a portion of the strip-shaped pad B is received in the third groove of the one-blade clamping assembly 1000, and another portion of the strip-shaped pad B is received in the third limiting groove of another clamping assembly 1000. Alternatively, a portion of the strip-shaped pad B is received in the fourth groove 423 of the one-blade clamping assembly 1000, and another portion of the strip-shaped pad B is received in the fourth limiting groove 411 of another clamping assembly 1000. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular.

[0061] It is understandable that the matching of the strip-shaped pad B with the first limiting groove 111 and the first recess 123, the second limiting groove 211 and the second recess 223, the third limiting groove and the third recess, and the fourth limiting groove 411 and the fourth recess 423 needs to be selected and matched according to actual needs. This embodiment will not provide examples of each one.

[0062] It should be noted that the limiting part of the strip-shaped pad B is composed of the body of the strip-shaped pad B, thereby simplifying the structure of the pad B.

[0063] In this embodiment, the cutter assembly 1000 includes a first cutter 1 and a second cutter 2. The first cutter 1 is used to cross and engage with the second cutter 2. The first cutter 1 and the second cutter 2 together enclose a first limiting space A, which is used to limit the movement of accessories housed in the packaging box. Through the above structure, the cross-engaging structure of the first cutter 1 and the second cutter 2 can be used to limit the movement of accessories. Moreover, the engaging structure is a detachable connection method, making it convenient to pick up and put down accessories. The detachable nature also allows the cutter assembly 1000 to be recycled, improving the resource utilization rate of the packaging box using the cutter assembly 1000 and avoiding resource waste.

[0064] This utility model also provides an embodiment of a packaging box, which includes a box body, at least one padding layer B, and the aforementioned card-holding assembly 1000. For the structure and function of the card-holding assembly 1000, please refer to the above embodiment; details will not be repeated here. The box body is provided with a receiving cavity; both the card-holding assembly 1000 and the padding layer B are housed within the receiving cavity, and the card-holding assembly 1000 abuts against the inner wall of the receiving cavity. When the number of card-holding assemblies 1000 is greater than or equal to two, the two card-holding assemblies 1000 together clamp multiple padding layers B.
