Detailed Implementation

[0066] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The manner described in the following exemplary embodiments does not represent all manner consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0067] As described in the technical background above, existing cash registers require adjustment of the display angle to ensure clear viewing for both users and customers when used in different locations due to variations in placement height and location. However, current dual-screen cash registers on the market have several issues: firstly, the rotation angle between the first and second screens is limited, typically between 0° and 45°, with a maximum of 60°, and the display orientation is fixed, failing to meet the needs for multi-angle and multi-directional display; secondly, most displays cannot be rotated, significantly restricting the cash register's usability in various scenarios. Furthermore, the base design of the cash register also presents certain limitations.

[0068] Meanwhile, to ensure stability, traditional cash registers typically have large bases, which not only increase packaging volume and costs for packaging, storage, and transportation, but may also affect users' willingness to purchase. Although some cash registers adopt a detachable base design to reduce packaging volume, this design requires users to install the base themselves after purchase, increasing the complexity of secondary assembly, causing inconvenience, and also affecting user experience and purchasing enthusiasm to some extent. Therefore, how to design a cash register that can flexibly adjust the display angle and has a foldable base has become an urgent technical problem to be solved.

[0069] Based on this, this application provides a cash register terminal. (Refer to...) Figure 1 , Figure 2 , Figure 8 and Figure 9 The POS terminal includes a support assembly 1, a display assembly, and a steering assembly. The support assembly 1 includes a main support member 10. The display assembly includes a first display screen 2 and a second display screen 3 disposed on both sides of the main support member 10. The steering assembly includes a first rotating bracket 20 and a second rotating bracket 30.

[0070] This application achieves independent multi-angle adjustment of the first display screen 2 and the second display screen 3 relative to the main support member 10 by setting a dual-axis steering assembly. Specifically, one end of the first rotating bracket 20 is rotatably connected to the first side of the main support member 10 about a first horizontal axis Z1, allowing the first display screen 2 to be adjusted vertically. Simultaneously, the first display screen 2 is also rotatably connected to the other end of the first rotating bracket 20 about a second axis Z2, enabling horizontal adjustment of the first display screen 2. Similarly, one end of the second rotating bracket 30 is rotatably connected to the second side of the main support member 10 about a first axis Z1, and the second display screen 3 is rotatably connected to the other end of the second rotating bracket 30 about a third axis Z3, thereby enabling independent adjustment of the second display screen 3.

[0071] In this design, the first axis Z1, the second axis Z2, and the third axis Z3 are all orthogonal to each other and intersect at the center of the main support 10. This design allows the display screen to be flexibly adjusted in three-dimensional space to meet the viewing needs of users and customers in different scenarios. For example, in convenience stores, supermarkets, and other places, the height and position of the checkout counter vary. By adjusting the display screen at multiple angles, the content can be clearly seen at various heights and positions, improving the user experience. In addition, this multi-angle adjustment function also allows users to adjust the display screen to landscape or portrait mode according to actual needs, further expanding the application scenarios of the POS terminal and enabling it to adapt to more business environments and usage requirements.

[0072] Specifically, refer to Figure 14 Figures 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, and 1-8 illustrate the angle diagrams of the first display screen 2 and the second display screen 3 in a partial POS terminal. It should be noted that this application is not limited to these. In this design, the first display screen 2 and the second display screen 3 have a wide range of adjustable angles to meet the needs of different scenarios. For example, the first display screen 2 can be vertically rotated within a range of 0° to 90° around a first horizontal axis Z1, and horizontally adjusted within a range of 0° to 180° around a second axis Z2; similarly, the second display screen 3 can also be adjusted independently. This multi-angle adjustment function allows the POS terminal to flexibly adapt to users and customers of different heights and viewing angles, ensuring that the display content is clearly visible in various situations, effectively improving the practicality of the device and the user experience. Furthermore, the precise design of the pivot assembly ensures the stability and accuracy of the display screen during adjustment, further enhancing the reliability and durability of the device.

[0073] From a technical implementation perspective, the dual-axis steering assembly design in this application not only provides a high degree of freedom in adjustment but also ensures structural compactness and stability through the orthogonal arrangement of the axes. This design avoids interference problems caused by display screen adjustment while maintaining the overall balance and durability of the device. For users, this adjustment method is simple to operate, requiring no complex tools or professional skills to quickly adjust the display screen angle, significantly improving the ease of use and adaptability of the device.

[0074] In summary, the POS terminal of this application, through the design of a dual-axis steering component, not only solves the limitations of existing POS machines in terms of display screen adjustment, but also improves the user experience and expands the application range of the device through flexible adjustment functions and a stable structural design, providing greater convenience and flexibility for use in different business scenarios.

[0075] In some implementations, refer to Figure 5The end of the first rotating bracket 20 rotatably connected to the main support member 10 is defined as the first support-side connection end 100, and the end of the first rotating bracket 20 connected to the first display screen 2 is defined as the first display-side connection end 200. (Refer to...) Figure 6 The end of the second rotating bracket 30 that is rotatably connected to the main support member 10 is defined as the second support side connection end 300, and the end of the second rotating bracket 30 that is connected to the second display screen 3 is defined as the second display side connection end 400.

[0076] Continue to refer to Figure 1 The steering assembly also includes a pivot assembly, which includes a first pivot 40 and a second pivot 50. The first support side connection end 100 of the first rotating bracket 20 is rotatably connected to the main support member 10 via the first pivot 40 and the second pivot 50, and the second support side connection end 300 of the second rotating bracket 30 is rotatably connected to the main support member 10 via the first pivot 40 and the second pivot 50. The first pivot 40 and the second pivot 50 are arranged at intervals along the direction of the first axis Z1, and their central axes are collinear with the first axis Z1.

[0077] This configuration allows the first display screen 2 and the second display screen 3 to be independently adjusted at multiple angles relative to the main support 10. The arrangement of the first pivot 40 and the second pivot 50 not only enhances the stability of the rotational connection but also enables flexible vertical rotation of the first display screen 2 and the second display screen 3.

[0078] Secondly, the compact design of the pivot assembly helps reduce the overall size of the device and improve space utilization, while ensuring smooth and precise rotation, thus enhancing the user experience.

[0079] In some implementations, refer to Figure 4 The main support member 10 includes a first mounting ear 110 and a second mounting ear 120 spaced apart along the first axis Z1. (Refer to...) Figure 5 The first support-side connecting end 100 includes a third mounting ear 210 and a fourth mounting ear 220 spaced apart along the first axis Z1. (Refer to...) Figure 6 The second support side connection end 300 includes a fifth mounting ear 310 and a sixth mounting ear 320 spaced apart along the first axis Z1.

[0080] Specifically, refer to Figure 3A first pivot 40 is rotatably mounted through a first mounting ear 110, a third mounting ear 210, and a fifth mounting ear 310, forming a first revolute joint 500, enabling the first rotating bracket 20 and the second rotating bracket 30 to rotate synchronously or asynchronously around a first axis Z1. A second pivot 50 is rotatably mounted through a second mounting ear 120, a fourth mounting ear 220, and a sixth mounting ear 320, forming a second revolute joint 600, further enhancing the stability and load-bearing capacity of the structure.

[0081] This configuration, through the cooperation of multiple mounting ears and pivots, not only achieves a reliable connection between the rotating bracket and the main support 10, but also ensures the stability and accuracy of the display screen during adjustment. Furthermore, by rationally arranging the position and spacing of the mounting ears, the entire steering assembly minimizes its size and weight while meeting mechanical strength requirements, thereby optimizing the overall design of the POS terminal and enhancing the product's market competitiveness.

[0082] In some embodiments, the pivot assembly further includes a third preload assembly. (See also...) Figure 7 The third pre-tightening structure includes a butterfly washer 401 sleeved on the main shaft (first pivot 40 or second pivot 50) and a nut 402 screwed onto the main shaft.

[0083] Taking the assembly process of the first rotating joint 500 as an example, refer to Figure 3 and Figure 7 First, a butterfly-shaped washer 401 is fitted onto the first pivot 40. Then, the first pivot 40 is sequentially passed through the fifth mounting ear 310, the first mounting ear 110, and the third mounting ear 210. Finally, a nut 402 is fitted onto the end of the first pivot 40 and tightened. When the nut 402 is tightened, a preload is applied to the butterfly-shaped washer 401, causing it to elastically deform and thus generating continuous pressure in the rotating joint. This design effectively prevents gaps caused by loosening of rotating parts during long-term use, ensuring the reliability and stability of the rotating connection. Simultaneously, the elastic deformation of the butterfly-shaped washer 401 also provides a certain damping effect, making the adjustment of the first display screen 2 and the second display screen 3 more stable and precise, improving the user's operating experience. Furthermore, by adjusting the tightness of the nut, the pressure of the butterfly-shaped washer can be fine-tuned to adapt to different usage scenarios and needs, further enhancing the flexibility and adaptability of the POS terminal.

[0084] Similarly, during the assembly of the second revolute joint 600, a butterfly washer 401 is first fitted onto the second pivot 50. Then, the second pivot 50 is sequentially passed through the sixth mounting ear 320, the second mounting ear 120, and the fourth mounting ear 220. Finally, a nut 402 is fitted onto the end of the second pivot 40 and tightened. When the nut 402 is tightened, a preload is applied to the butterfly washer 401, causing it to elastically deform and thus generating continuous pressure within the revolute joint. The resulting effect is the same as that of the first revolute joint 500 described above, and will not be repeated here.

[0085] In some implementations, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The steering assembly also includes a first limiting structure, which is respectively disposed in the first rotary joint 500 and the second rotary joint 600. The first limiting structure includes a first limiting boss 130, a first limiting groove 230 and a second limiting groove 330.

[0086] In one embodiment, a first limiting structure is provided in the first rotating joint 500. Specifically, a first limiting boss 130 structure is provided on both axial end faces of the first mounting ear 110. A first limiting groove 230 is formed on the axial end face of the third mounting ear 210 near the first mounting ear 110, and a second limiting groove 330 is formed on the axial end face of the fifth mounting ear 310 near the first mounting ear 110. The first limiting groove 230 on the third mounting ear 210 cooperates with the first limiting boss 130 near the third mounting ear 210 to limit the rotation of the first rotating bracket 20. The second limiting groove 330 on the fifth mounting ear 310 cooperates with the first limiting boss 130 near the fifth mounting ear 310 to limit the rotation of the second rotating bracket 30.

[0087] In one embodiment, a first limiting structure is provided in the second rotary joint 600. Specifically, continue to refer to... Figure 3 , Figure 4 , Figure 5 and Figure 6 A first limiting boss 130 structure is provided on both axial end faces of the second mounting ear 120. A first limiting groove 230 is formed on the axial end face of the fourth mounting ear 220 near the second mounting ear 120, and a second limiting groove 330 is formed on the axial end face of the sixth mounting ear 320 near the second mounting ear 120. The first limiting groove 230 on the fourth mounting ear 220 cooperates with the first limiting boss 130 near the fourth mounting ear 220 to limit the rotation of the first rotating bracket 20. The second limiting groove 330 on the sixth mounting ear 320 cooperates with the first limiting boss 130 near the sixth mounting ear 320 to limit the rotation of the second rotating bracket 30.

[0088] The first limiting mechanism provided in this application can effectively limit the rotation angle of the first rotating bracket 20 and the second rotating bracket 30 in the vertical direction, thereby preventing the first display screen 2 and the second display screen 3 from interfering with each other during rotation.

[0089] In some embodiments, the first limiting boss 130 includes a limiting surface 1301.

[0090] In one embodiment, refer to Figure 4 and Figure 5 The limiting surface 1301 abuts against the end face of the first limiting groove 230 at a ±90° rotation position. Specifically, when the first rotating bracket 20 rotates to the ±90° position, the limiting surface 1301 of the first limiting boss 130 will be in close contact with the end face of the corresponding first limiting groove 230, thereby preventing further rotation. This design ensures that the rotation angle of the display screen in the vertical direction is limited to a safe and practical range, effectively preventing structural damage or interference between display screens caused by excessive rotation. At the same time, precise limit control improves the stability of the device and the user's operating experience.

[0091] In one embodiment, refer to Figure 4 and Figure 6 The limiting surface 1301 and the end face of the second limiting groove 330 abut against each other at a ±90° rotation position.

[0092] Specifically, when the second rotating bracket 30 rotates to a position of ±90°, the limiting surface 1301 of the first limiting boss 130 will make tight contact with the end face of the corresponding second limiting groove 330, thereby preventing further rotation. This design ensures that the rotation angle of the display screen in the vertical direction is limited to a safe and practical range, effectively preventing structural damage or interference between display screens caused by excessive rotation. At the same time, precise limit control improves the stability of the device and the user's operating experience.

[0093] In some implementations, refer to Figure 10 When the display sides of the first display screen 2 and the second display screen 3 are both located on the same plane, the distance between the edge of the first display screen 2 near the pivot assembly and the center point of the pivot assembly is the first pitch E1, and the distance between the edge of the second display screen 3 near the pivot assembly and the center point of the pivot assembly is the second pitch E2. The first pitch E1 and the second pitch E2 are equal.

[0094] This arrangement ensures the symmetry and coordination of the two displays in terms of spatial layout, helping to maintain the overall balance and stability of the POS terminal. By making the first pitch E1 and the second pitch E2 equal, it can be guaranteed that the movement trajectories of the two displays will not interfere when the display angle is adjusted, thus improving the reliability and lifespan of the equipment.

[0095] In some implementations, refer to Figure 8 , Figure 9 and Figure 10 The steering assembly also includes a first rotating component 60 and a second rotating component 70. The first rotating component 60 is located on the non-display side of the first display screen 2, and the second rotating component 70 is located on the non-display side of the second display screen 3. The first display screen 2 is rotatably connected to the first display side connection end 200 of the first rotating bracket 20 via the first rotating component 60, and the second display screen 3 is rotatably connected to the second display side connection end 400 of the second rotating bracket 30 via the second rotating component 70.

[0096] Specifically, the first rotating assembly 60 includes a first connector 610 located on the non-display side of the first display screen 2 and a first mating member 620 located on the first display side connection end 200 of the first rotating bracket 20. The first connector 610 and the first mating member 620 are connected by a first fastener 650 to form a third rotating pair 700.

[0097] This configuration allows the first display screen 2 to be rotated relative to the first rotating bracket 20, increasing the flexibility and adjustability of the display screen.

[0098] Specifically, the second rotating assembly 70 includes a second connector 710 located on the non-display side of the second display screen 3, and a second mating member 720 located on the second display side connection end 400 of the second rotating bracket. The second connector 710 and the second mating member 720 are connected by a second fastener 750 to form a fourth rotating pair 800. Similarly, this arrangement allows the second display screen 3 to also be subject to additional rotational adjustments relative to the second rotating bracket 30.

[0099] The beneficial effects of the first rotating component 60 and the second rotating component 70 are mainly reflected in the following aspects:

[0100] First, by setting a rotating component on the non-display side of the display screen, the display screen can not only rotate around the first axis with the rotating bracket, but also rotate and adjust within its own plane, thereby better adapting to different display needs and viewing angles.

[0101] Secondly, the compact design of the rotating components allows the display screen to be adjusted in multiple directions within a limited space, avoiding the problem of excessive space being occupied by an oversized adjustment mechanism, making the overall design of the POS terminal more compact and reasonable.

[0102] Furthermore, users can easily adjust the angle and orientation of the display screen according to actual usage scenarios and needs, without the need for complicated disassembly and reinstallation processes, thus improving the ease of use of the device and user satisfaction.

[0103] Finally, the rotating components and rotating brackets connected by fasteners ensure the stability and reliability of the structure during the adjustment of the display screen, reducing the risk of poor display effect or equipment damage due to loosening or shaking.

[0104] In one embodiment, refer to Figure 8 and Figure 9 The first connector 610 and the second connector 710 are configured as connecting shafts, the first mating part 620 and the second mating part 720 are configured as connecting holes, and the first fastener 650 and the second fastener 750 are configured as lock nuts.

[0105] Specifically, align the connecting shaft on the non-display side of the first display screen 2 with the connecting hole on the first rotating bracket 20 and insert it, then tighten the locking nut to complete the connection between the first display screen 2 and the first rotating bracket 20.

[0106] Similarly, align the connecting shaft on the non-display side of the second display screen 3 with the connecting hole on the second rotating bracket 30 and insert it, then tighten the locking nut to complete the connection between the second display screen 3 and the second rotating bracket 30.

[0107] In some embodiments, the steering assembly further includes a second limiting structure located in the third rotary joint 700 and the fourth rotary joint 800, respectively, including a second limiting boss 240, a third limiting boss 340, a third limiting groove 6100 and a fourth limiting groove 7100.

[0108] In one embodiment, a second limiting structure is provided in the third rotary joint 700. Specifically, refer to... Figure 3 , Figure 8 and Figure 10 A second limiting boss 240 structure is provided at the first display side connection end 200 of the first rotating bracket 20, and a third limiting groove 6100 is provided on the non-display side of the first display screen 2. The third limiting groove 6100 cooperates with the second limiting boss 240 to limit the rotation of the first display screen 2.

[0109] In one embodiment, a second limiting structure is provided in the fourth rotary joint 800. Specifically, refer to... Figure 3 , Figure 9 and Figure 10 A third limiting boss 340 structure is provided at the second display side connection end 400 of the second rotating bracket, and a fourth limiting groove 7100 is provided on the non-display side of the second display screen 3. The fourth limiting groove 7100 cooperates with the third limiting boss 340 to limit the rotation of the second display screen 3.

[0110] The second limiting mechanism provided in this application effectively restricts the rotation of the first display screen 2 and the second display screen 3 within their respective planes, preventing interference between them during rotation. This design ensures the stability and safety of the display screens when adjusting their angles, preventing structural damage or obstruction of displayed content due to excessive rotation. Simultaneously, precise limiting control enhances the reliability of the device and the user experience, enabling the POS terminal to maintain good display quality and mechanical performance in various usage scenarios.

[0111] In some embodiments, the first rotating assembly 60 further includes a first preload assembly. The first preload assembly is used to enhance the stability of the connection and the precision of adjustment.

[0112] Specifically, refer to Figure 8 The first pre-tightening component includes a first friction element 630 and a first elastic element 640. The first friction element 630 is disposed between the first connecting member 610 and the first mating member 620, increasing friction to prevent loosening and unnecessary rotation at the connection, ensuring that the first display screen 2 can stably maintain its position after being adjusted to the desired angle. The first elastic element 640 is disposed between the first mating member 620 and the first fastener 650, providing continuous elastic pressure to make the connection between the first connecting member 610 and the first mating member 620 tighter, further improving the reliability of the connection and the accuracy of adjustment. This design not only effectively reduces the problem of loosening due to long-term use or external forces, but also improves the user's operating experience when adjusting the display screen angle, making the adjustment process smoother and more precise. Furthermore, the first pre-tightening component has a simple structure, low cost, and is easy to install and maintain, bringing convenience to the overall design and use of the POS terminal. Preferably, the first elastic element 640 can be configured as a butterfly-shaped spring.

[0113] In one embodiment, during the assembly of the third rotary joint 700, the first friction element 630 is first fitted onto the connecting shaft (first connector 610) on the non-display side of the first display screen 2. In this step, the first friction element 630 fits tightly against the connecting shaft, providing the necessary friction for subsequent assembly. Next, the first rotating bracket 20 is fitted onto the connecting shaft with the first friction element 630 installed through the connecting hole (first mating part 620), ensuring a tight and smooth fit between the first rotating bracket 20 and the connecting shaft. Subsequently, a butterfly spring is fitted onto the end of the connecting shaft and tightened with a locking nut (first fastener 650). When the locking nut is tightened, the butterfly spring undergoes elastic deformation, generating continuous pressure between the connecting shaft and the first rotating bracket 20. This pressure not only effectively prevents loosening at the connection point but also provides a certain damping effect, making the first display screen 2 more stable and precise when adjusting its angle. The entire assembly process is simple and efficient, and the tight fit of each component ensures the stability and reliability of the third rotary joint 700 during long-term use.

[0114] In some embodiments, the second rotating assembly 70 includes a second preload assembly. The second preload assembly is used to enhance the stability of the connection and the precision of adjustment.

[0115] Specifically, refer to Figure 9 The second pre-tightening component includes a second friction element 730 and a second elastic element 740. The second friction element 730 is disposed between the second connector 710 and the second mating member 720, increasing friction to prevent loosening and unnecessary rotation at the connection, ensuring that the second display screen 3 can stably maintain its position after being adjusted to the desired angle. The second elastic element 740 is disposed between the second mating member 720 and the second fastener 750, providing continuous elastic pressure to make the connection between the second connector 710 and the second mating member 720 tighter, further improving the reliability of the connection and the accuracy of adjustment.

[0116] In one embodiment, during the assembly of the fourth rotary joint 800, the second friction element 730 is first fitted onto the connecting shaft (second connector 710) on the non-display side of the second display screen 3. In this step, the second friction element 730 fits tightly against the connecting shaft, providing the necessary friction for subsequent assembly. Next, the second rotary bracket 30 is fitted onto the connecting shaft with the second friction element 730 installed through the connecting hole (second mating part 720), ensuring a tight and smooth fit between the second rotary bracket 30 and the connecting shaft. Subsequently, the butterfly spring is fitted onto the end of the connecting shaft and tightened with a lock nut (second fastener 750). The specific effect can be referenced to the effect of the first pre-tightening component in the third rotary joint 700, and will not be elaborated further here.

[0117] In some implementations, refer to 1. Figure 10 and Figure 11 The support assembly 1 also includes a base 11, which includes a base plate 111 and a movable extension plate 112. The main support member 10 is detachably connected to the base plate 111, and the movable extension plate 112 can be folded relative to the base plate 111 within the range of 0° to 90°.

[0118] In one embodiment, refer to Figure 10 The base plate 111 is fixedly installed on the main support member 10, serving as a stable foundation for the entire base 11 structure.

[0119] Reference Figure 11 and Figure 12 The movable expansion plate 112 is connected to the base plate 111 via the slide groove 113 and the slide shaft 114 to form a movable structure.

[0120] Specifically, when a POS terminal is needed, refer to... Figures 13a to 13d The movable extension plate 112 can rotate around its axis until it is flush with the base plate 111, thus forming a spacious and stable support surface. After the movable extension plate 112 is rotated into place, the tight engagement of the sliding shaft 114, the slot (not shown in the figure), and the latch (not shown in the figure) ensures a secure connection between the movable extension plate 112 and the base plate 111, preventing displacement or shaking during use. It is understood that... Figures 13a to 13b to Figures 13c to 13d The order of the displayed structures represents the sequence of steps in using the POS terminal.

[0121] Specifically, when the POS terminal needs to be packaged or stored, the operator must first pull the movable extension plate 112 to a certain position, aligning the hole at the end of the slide 113 with the shaft, before the movable extension plate can be easily folded up. This design ensures that the movable extension plate will not interfere with or damage other components during the folding process, while also facilitating quick packaging operations and improving overall ease of use. Understandably, Figures 13d to 13c to Figures 13b to 13a The order of the displayed structures indicates the sequence of the POS terminal storage process.

[0122] In some embodiments, to prevent the movable extension plate from accidentally flipping over when not in use or during packaging and transportation, the sliding shaft 114 on the base plate 111 is specially processed in the middle section and designed to be flat, effectively restricting the flipping of the movable extension plate 112. This design not only increases the stability of the structure, but also makes the entire base 11 more compact and space-saving when stored and transported.

[0123] The design of this base 11 offers several advantages in practical applications. Firstly, it allows for flexible adjustment of the base plate's size and shape to suit different usage needs. The movable extension plate can be deployed when a larger support surface is required, while it can be folded up when space is limited or for transport, significantly improving the device's adaptability and portability. Secondly, through a well-designed mechanical structure, such as the coordinated use of components like the slide groove 113, slide shaft 114, slots, and buckles, the stability and reliability of the base 11 during use and storage are ensured, extending the device's lifespan. Furthermore, this design prioritizes ease of operation; users can easily unfold and fold up the base 11 without the need for additional tools or complicated procedures, thus enhancing the user experience.

[0124] In some embodiments, a corrugated structure 115 is also provided on the outer surface of the movable extension plate 112, which can hold items such as pens and prevent them from being rolled away. Specifically, the corrugated structure 115 has a unique design, which is not only stylish in appearance but also highly practical.

[0125] Specifically, the corrugated structure 115 can be composed of a series of parallel wavy stripes, forming multiple slots. Each slot is wide enough to easily hold various stationery items, such as ballpoint pens, fountain pens, and markers, and can even accommodate small office supplies, such as sticky notes and paper clips. This design cleverly utilizes the surface space of the movable extension plate, making the POS terminal more functionally diverse.

[0126] Furthermore, the corrugated structure 115 can be made of a soft and elastic material, ensuring that items placed inside are securely fixed and will not fall due to minor external impacts or vibrations. This material is also wear-resistant and stain-resistant, easy to clean and maintain, ensuring the cleanliness and durability of the movable extension plate. In practical use, users can place frequently used stationery in the corrugated structure 115 for quick access when needed, greatly improving work efficiency. For example, in convenience stores or small supermarkets, cashiers can quickly grab a pen to record notes or fill out forms during busy work without having to search for stationery, reducing operation time and improving service efficiency.

[0127] Furthermore, the wavy stripe structure does not affect the folding function of the movable extension plate. When the extension plate needs to be folded up, the wavy structure 115 can fit tightly without taking up extra space, ensuring the overall compactness and portability of the POS terminal.
