DETAILED DESCRIPTION

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clear and understandable, the present application is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0039] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0040] It should also be noted that, in the embodiment of the present application, Figure 1 The XYZ rectangular coordinate system established in the definition is: the side located in the positive direction of the X axis is defined as the front, and the side located in the negative direction of the X axis is defined as the back; the side located in the positive direction of the Y axis is defined as the left, and the side located in the negative direction of the Y axis is defined as the right; the side located in the positive direction of the Z axis is defined as the top, and the side located in the negative direction of the Z axis is defined as the bottom.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0042] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0043] Currently, dictionary pens on the market typically have a trigger structure at the bottom, consisting of a feeler, a spring, and a microswitch. When the user presses the dictionary pen against the content to be scanned, the feeler retracts inward and triggers the microswitch, turning on the scanning function. When the user lifts the pen, the spring's elastic force resets the feeler, turning off the scanning function. As a result, the trigger structure is complex and takes up a lot of space, limiting the design and development of dictionary pens. This results in a high degree of homogeneity among dictionary pens on the market and a relatively monotonous user experience.

[0044] Therefore, some embodiments of the present application provide a new type of dictionary pen, which can detect the user's pressing action on the front end of the shell in real time through a pressure sensor, and can turn on or off the scanning function according to the detection data of the pressure sensor.

[0045] In order to illustrate the technical solution provided by this application, a detailed description is given below with reference to specific drawings and embodiments.

[0046] Example 1

[0047] See also Figure 1 、 Figure 2 Some embodiments of the present application provide a dictionary pen, including a shell 10 and a pressure sensor 20. The front end of the shell 10 is provided with an opening 11 that passes through in the up-down direction. The shell 10 has a front wall structure 12 located in front of the opening 11, and two side wall structures 13 located on the left and right sides of the opening 11 respectively; the pressure sensor 20 is provided in the opening 11 and is installed on the front wall structure 12 or the side wall structure 13. The pressure sensor 20 is used to detect the user's pressing action on the front end of the shell 10. The dictionary pen can turn on or off the scanning function according to the detection data of the pressure sensor 20.

[0048] It should be noted that the housing 10 can be an integrally formed structure or a split, connected structure, and this embodiment does not impose any restrictions on this. The front end of the housing 10 is provided with an opening 11 extending vertically therethrough, and the pressure sensor 20 is disposed within the opening 11. This arrangement allows the housing 10 to provide dustproof and waterproof protection for the pressure sensor 20, thereby ensuring the performance and service life of the pressure sensor 20.

[0049] At least one pressure sensor 20 is provided. When only one pressure sensor 20 is provided, the single pressure sensor 20 can be installed on the front wall structure 12 or the side wall structure 13. When multiple pressure sensors 20 are provided, multiple pressure sensors 20 can be installed on the front wall structure 12 and / or the side wall structure 13, respectively. This embodiment does not impose any limitation on this.

[0050] Since the pressure sensor 20 is installed on the front wall structure 12 or the side wall structure 13, when the front wall structure 12 or the side wall structure 13 on which the pressure sensor 20 is installed is subjected to stress and causes at least local strain, the pressure sensor 20 can detect the strain amount and changes in its coverage area, so as to identify and detect "whether the user has pressed the front end of the shell 10" based on this.

[0051] It should also be noted here that the lower side opening of the opening 11 forms a scanning window, and the dictionary pen also includes a scanning module (not shown in the figure) connected to the signal of the pressure sensor 20. According to the detection data of the pressure sensor 20, when the pressure sensor 20 recognizes that the user presses the front end of the shell 10, the scanning module can turn on the scanning function and scan and read the scanned content through the scanning window, otherwise the scanning module will turn off the scanning function.

[0052] Therefore, the scanning pen provided in the embodiment of the present application can bear the pressing force through the front wall structure 12 and transmit the pressing force to the front wall structure 12 and the side wall structure 13 when the user holds the dictionary pen and presses the front end of the shell 10 of the dictionary pen on the scanning content, and through the stress, at least part of the front wall structure 12 or the side wall structure 13 where the pressure sensor 20 is installed is strained. Based on this, the pressure sensor 20 can detect the strain amount and change of its coverage area, so as to identify and detect "whether the user has pressed the front end of the shell 10". According to the detection data of the pressure sensor 20, the dictionary pen can turn on the scanning function when the pressure sensor 20 identifies and detects that the user has pressed the front end of the shell 10, otherwise the dictionary pen turns off the scanning function.

[0053] Therefore, compared with the existing dictionary pens, the dictionary pen provided in the embodiment of the present application can significantly simplify the number of components and structural complexity of the related structures used to trigger the dictionary pen to turn on or off the scanning function, can significantly save the space occupied by the related structures used to trigger the dictionary pen to turn on or off the scanning function, can provide more possibilities for the design and development of the dictionary pen, and can effectively improve the user experience of the dictionary pen.

[0054] See also Figure 1 、 Figure 2In this embodiment, the pressure sensor 20 is installed on the sidewall structure 13, and the sidewall structure 13 has a strain detection area 131. The pressure sensor 20 covers at least a portion of the strain detection area 131, and the strain detection area 131 is provided with a first stress groove 1311.

[0055] Based on the setting of this embodiment, when the user holds the dictionary pen and presses the front end of the dictionary pen shell 10 on the scanned content, the front wall structure 12 can bear the pressing force and transmit the pressing force to the side wall structure 13. Subsequently, based on the first stress groove 1311 set in the strain detection area 131 of the side wall structure 13, the stress can be concentrated at and near the first stress groove 1311, so that the strain detection area 131 is subjected to concentrated stress and generates concentrated strain at and near the first stress groove 1311. Therefore, the pressure sensor 20 that at least covers the local area of ​​the strain detection area 131 can sensitively, reliably and effectively detect the strain amount and change of its coverage area, so as to accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0056] In this embodiment, the parameters such as the groove depth and groove width of the first stress groove 1311 are not limited exclusively.

[0057] See also Figure 1 、 Figure 2 In this embodiment, the first stress groove 1311 is extended along the up-down direction and is penetrated along the up-down direction.

[0058] By extending the first stress groove 1311 in the up-down direction and setting it through in the up-down direction, the extension direction of the first stress groove 1311 can be intersected with or even perpendicular to the stress direction, which can relatively weaken the structural strength of the strain detection area 131 at and near the first stress groove 1311, and ensure the structural strength of the strain detection area 131 at the front and rear sides of the first stress groove 1311. Based on this, the stress can be concentrated at and near the first stress groove 1311, and the strain detection area 131 can be subjected to concentrated stress to generate concentrated compressive strain at and near the first stress groove 1311, thereby facilitating the pressure sensor 20 to sensitively, reliably and effectively detect the strain amount and changes, and accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0059] Of course, in other possible implementations, the first stress groove 1311 may be formed by extending along other directions; and / or, the first stress groove 1311 may be arranged non-through along its extension direction; and / or, a plurality of first stress grooves 1311 may be provided, and the plurality of first stress grooves 1311 are arranged crosswise; this embodiment does not impose any restrictions on this.

[0060] See also Figure 1 、 Figure 2In this embodiment, the side wall structure 13 is an integrally formed structure. This configuration facilitates the processing of the side wall structure 13 and simplifies the assembly process of the side wall structure 13.

[0061] See also Figure 1 、 Figure 2 In this embodiment, a plurality of pressure sensors 20 are provided, and the plurality of pressure sensors 20 are respectively arranged on the two side wall structures 13 .

[0062] Based on the setting of this embodiment, when the user holds the dictionary pen and presses the front end of the shell 10 of the dictionary pen on the scanned content, the front wall structure 12 can bear the pressing force and transmit the pressing force to the two side wall structures 13. Subsequently, the multiple pressure sensors 20 respectively arranged on the two side wall structures 13 can respectively detect the strain and change of the corresponding side wall structures 13. Therefore, the detection data of multiple pressure sensors 20 can be integrated to accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0063] See also Figure 1 、 Figure 2 In this embodiment, the pressure sensor 20 is bonded to the front wall structure 12 or the side wall structure 13. Specifically, the pressure sensor 20 can be bonded to the front wall structure 12 or the side wall structure 13 using, but not limited to, double-sided tape 30, adhesive film, dispensing glue, or glue. This arrangement ensures and improves the convenience, reliability, and stability of the connection between the pressure sensor 20 and the front wall structure 12 or the side wall structure 13.

[0064] See also Figure 1 、 Figure 2 In this embodiment, the pressure sensor 20 is a polymer material pressure sensor 20 .

[0065] By adopting the above-mentioned solution, the pressure sensor 20 can have the characteristics of being solid, lightweight, soft, flexible, and impact-resistant, and can detect strains at the micron level, thereby ensuring and improving the performance and detection accuracy of the pressure sensor 20, and ensuring and extending the service life of the pressure sensor 20.

[0066] Of course, in other possible implementations, the pressure sensor 20 may also be a piezoresistive pressure sensor, a piezoelectric pressure sensor, a capacitive pressure sensor, or other types of sensors.

[0067] In the prior art, since the tentacles are movable parts, the existing dictionary pens cannot be effectively sealed at least at the tentacles, resulting in the existing dictionary pens being easily infiltrated with water and dust, thereby affecting the performance and service life of the existing dictionary pens.

[0068] For this, see Figure 1 、 Figure 2In this embodiment, the dictionary pen further includes two glass screens (not shown in the figure), which respectively seal and cover the upper and lower openings of the opening 11.

[0069] By adopting the above-mentioned scheme, the dictionary pen provided in this embodiment can, on the basis of setting the pressure sensor 20 in the opening 11, seal and cover the upper and lower openings of the opening 11 through two glass screens respectively, so as to achieve the purpose of enclosing the pressure sensor 20 in the internal space through the two glass screens and the shell 10. Based on this, the sealing, dustproof and waterproof properties of the dictionary pen can be effectively guaranteed and improved, the performance of the dictionary pen can be effectively guaranteed and improved, and the service life of the dictionary pen can be effectively guaranteed and extended.

[0070] Example 2

[0071] The difference between this embodiment and the first embodiment is that:

[0072] See also Figure 3 In this embodiment, the sidewall structure 13 includes a sidewall body 132 and a first structural member 133 installed on the inner side of the sidewall body 132 and forming a strain detection area 131. The first structural member 133 is provided with at least a portion of a first stress groove 1311.

[0073] By adopting the above-mentioned scheme, the side wall body 132 and the first structural member 133 forming the strain detection area 131 can be separately molded to facilitate the molding of the first structural member 133 and the first stress groove 1311; and then the first structural member 133 is installed to the inner side of the side wall body 132 by embedding or other means. In this way, the strain detection area 131 can also be subjected to concentrated stress and generate concentrated strain at and near the first stress groove 1311, so that the pressure sensor 20 can detect the strain amount and change of the strain detection area 131, and can identify and detect "whether the user has pressed the front end of the shell 10".

[0074] Example 3

[0075] The difference between this embodiment and the first embodiment is that:

[0076] See also Figure 4 、 Figure 5 In this embodiment, the pressure sensor 20 is installed on the front wall structure 12, and the front wall structure 12 includes a front wall body 121 and a load-bearing member 122. The front side of the front wall body 121 is provided with a mounting groove 1211, and the bottom of the mounting groove 1211 is provided with a hollow groove 1212. The load-bearing member 122 is installed in the mounting groove 1211, and the pressure sensor 20 is installed on the rear side of the load-bearing member 122. The pressure sensor 20 is spaced apart from the bottom of the hollow groove 1212.

[0077] It should be noted here that the edge portion of the load-bearing member 122 is supported by the bottom of the installation groove 1211, and the portion of the load-bearing member 122 corresponding to the hollow groove 1212 is suspended in the air. Based on this, the load-bearing member 122 can form a strain beam that can generate strain under stress.

[0078] The pressure sensor 20 is mounted on the rear side of the load-bearing member 122. When the load-bearing member 122 is stressed and strained, the pressure sensor 20 detects the amount of strain and changes in its coverage area, thereby identifying whether the user has pressed the front end of the housing 10. During this time, the hollow groove 1212, particularly the gap between the pressure sensor 20 and the bottom of the hollow groove 1212, creates a deformation space for the load-bearing member 122 and the pressure sensor 20 to deform.

[0079] Therefore, based on the setting of this embodiment, when the user holds the dictionary pen and presses the front end of the shell 10 of the dictionary pen on the scanned content, the load-bearing member 122 can bear the pressing force and produce strain due to the stress. Based on this, the pressure sensor 20 installed on the rear side of the load-bearing member 122 can detect the strain amount and change of its coverage area, so as to identify and detect "whether the user has pressed the front end of the shell 10". Subsequently, according to the detection data of the pressure sensor 20, the dictionary pen can turn on the scanning function when the pressure sensor 20 identifies and detects that the user has pressed the front end of the shell 10, otherwise turn off the scanning function.

[0080] See also Figure 4 、 Figure 5 In this embodiment, a second stress groove 1221 is provided on the rear side of the load-bearing member 122 .

[0081] By arranging a second stress groove 1221 on the rear side of the load-bearing member 122, the structural strength of the load-bearing member 122 at and near the second stress groove 1221 can be relatively weakened. Based on this, when the load-bearing member 122 bears the pressing force, the stress can be concentrated at and near the second stress groove 1221, making it easy for the load-bearing member 122 to generate concentrated strain at and near the second stress groove 1221. Therefore, the pressure sensor 20 can sensitively, reliably and effectively detect the strain amount and changes in its coverage area, so as to accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0082] See also Figure 4 、 Figure 5 In this embodiment, the second stress groove 1221 is formed to extend along the left-right direction.

[0083] By extending the second stress groove 1221 in the left-right direction, the extension direction of the second stress groove 1221 can be intersected with or even perpendicular to the stress direction, which can relatively weaken the structural strength of the load-bearing member 122 at and near the second stress groove 1221, and ensure the structural strength of the load-bearing member 122 at the upper and lower sides of the second stress groove 1221. Based on this, the stress can be concentrated at and near the second stress groove 1221, and the load-bearing member 122 can be subjected to concentrated stress and generate concentrated bending strain at and near the second stress groove 1221, thereby facilitating the pressure sensor 20 to sensitively, reliably and effectively detect the strain amount and changes, and accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0084] In this embodiment, the parameters such as the groove depth and groove width of the second stress groove 1221 are not limited exclusively.

[0085] Of course, in other possible implementations, the second stress groove 1221 may be set to be through or non-through along its extension direction; and / or, the second stress groove 1221 may be extended along other directions; and / or, multiple second stress grooves 1221 may be provided, and multiple second stress grooves 1221 are cross-arranged; this embodiment does not impose any restrictions on this.

[0086] Example 4

[0087] The difference between this embodiment and the first embodiment is that:

[0088] See also Figure 6 In this embodiment, the pressure sensor 20 is installed on the front wall structure 12, which includes a front wall body 121, a load-bearing member 122 and a second structural member 123. A mounting groove 1211 is provided on the front side of the front wall body 121, and a hollow groove 1212 is provided at the bottom of the mounting groove 1211. The load-bearing member 122 and the second structural member 123 are both installed in the mounting groove 1211, and the second structural member 123 is installed on the rear side of the load-bearing member 122. The pressure sensor 20 is installed on the rear side of the second structural member 123, and the pressure sensor 20 is spaced apart from the bottom of the hollow groove 1212.

[0089] It should be noted that the edge of the second structural member 123 is supported by the bottom of the mounting groove 1211, while the portion of the second structural member 123 corresponding to the hollow groove 1212 is suspended in the air. As a result, the second structural member 123 can form a strain beam that can generate strain under stress. The second structural member 123 can be, but is not limited to, a steel sheet.

[0090] The pressure sensor 20 is mounted on the rear side of the second structural member 123. When the second structural member 123 is subjected to stress and strain, the pressure sensor 20 detects the amount of strain and changes in its coverage area, thereby identifying whether the user has pressed the front end of the housing 10. During this time, the hollow groove 1212, particularly the gap between the pressure sensor 20 and the bottom of the hollow groove 1212, creates a deformation space for the second structural member 123 and the pressure sensor 20 to deform.

[0091] Therefore, based on the setting of this embodiment, when the user holds the dictionary pen and presses the front end of the shell 10 of the dictionary pen on the scanned content, the load-bearing member 122 can bear the pressing force and transfer the pressing force to the second structural member 123. Subsequently, the second structural member 123 can be subjected to stress and produce strain. Based on this, the pressure sensor 20 installed on the rear side of the second structural member 123 can detect the strain amount and change of its coverage area, so as to identify and detect "whether the user has pressed the front end of the shell 10". Subsequently, according to the detection data of the pressure sensor 20, the dictionary pen can turn on the scanning function when the pressure sensor 20 identifies and detects that the user has pressed the front end of the shell 10, otherwise turn off the scanning function.

[0092] See also Figure 6 In this embodiment, a third stress groove 124 is provided on the rear side of the second structural member 123 .

[0093] By providing the third stress groove 124 on the rear side of the second structural member 123, the structural strength of the second structural member 123 at and near the third stress groove 124 can be relatively weakened. Based on this, when the second structural member 123 is subjected to stress, the stress can be concentrated at and near the third stress groove 124, making it easy for the second structural member 123 to generate concentrated strain at and near the third stress groove 124. As a result, the pressure sensor 20 can sensitively, reliably and effectively detect the strain amount and changes in its coverage area, so as to accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0094] See also Figure 6 In this embodiment, the third stress groove 124 is formed to extend along the left-right direction.

[0095] By extending the third stress groove 124 in the left-right direction, the extension direction of the third stress groove 124 can be intersected with or even perpendicular to the stress direction, which can relatively weaken the structural strength of the second structural member 123 at and near the third stress groove 124, and ensure the structural strength of the second structural member 123 at the upper and lower sides of the third stress groove 124. Based on this, the stress can be concentrated at and near the third stress groove 124, and the second structural member 123 can be subjected to concentrated stress and generate concentrated bending strain at and near the third stress groove 124, thereby facilitating the pressure sensor 20 to sensitively, reliably and effectively detect the strain amount and change, and accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0096] In this embodiment, the parameters such as the groove depth and groove width of the third stress groove 124 are not limited exclusively.

[0097] Of course, in other possible implementations, the third stress groove 124 may be provided through or not along its extension direction; and / or, the third stress groove 124 may be extended along other directions; and / or, a plurality of third stress grooves 124 may be provided, and the plurality of third stress grooves 124 may be cross-arranged; this embodiment does not impose any limitation on this.

[0098] Example 5

[0099] See also Figure 7 In this embodiment, a third stress groove 124 is provided on the rear side of the load-bearing member 122 .

[0100] By relocating the third stress groove 124 to the rear side of the load-bearing member 122, the structural strength of the load-bearing member 122 at and near the third stress groove 124 can be relatively weakened. Based on this, when the load-bearing member 122 bears the pressing force, the stress can be concentrated at and near the third stress groove 124, making it easy for the part of the second structural member 123 corresponding to and near the third stress groove 124 to produce concentrated strain. Therefore, the pressure sensor 20 can sensitively, reliably and effectively detect the strain amount and changes in its coverage area, so as to accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0101] Example 6

[0102] The difference between this embodiment and the first embodiment is that:

[0103] See also Figure 8In this embodiment, the pressure sensor 20 is installed on the front wall structure 12. The front wall structure 12 includes a front wall body 121 and a load-bearing member 122. The front wall body 121 is provided with a mounting groove 1211 on its front side surface. The load-bearing member 122 is installed in the mounting groove 1211. The bottom of the mounting groove 1211 is provided with a fourth stress groove 1213. The pressure sensor 20 is installed on the rear side of the front wall body 121 and is arranged corresponding to the mounting groove 1211.

[0104] Based on the setting of this embodiment, when the user holds the dictionary pen and presses the front end of the dictionary pen shell 10 on the scanned content, the load-bearing member 122 can bear the pressing force and transfer the pressing force to the bottom of the mounting groove 1211. Subsequently, based on the fourth stress groove 1213 set at the bottom of the mounting groove 1211, the stress can be concentrated at and near the fourth stress groove 1213, so that the bottom of the mounting groove 1211 is subjected to concentrated stress and concentrated strain is generated at and near the fourth stress groove 1213. Therefore, the pressure sensor 20 installed on the rear side of the front wall main body 121 and corresponding to the mounting groove 1211 can sensitively, reliably and effectively detect the strain amount and changes in its coverage area, so as to accurately identify and detect "whether the user has pressed the front end of the shell 10" based on this.

[0105] In this embodiment, parameters such as the groove width of the fourth stress groove 1213 are not limited exclusively.

[0106] See also Figure 8 In this embodiment, the fourth stress groove 1213 is set to penetrate along the front-to-back direction.

[0107] By setting the fourth stress groove 1213 through in the front-to-back direction, the portion of the bottom of the installation groove 1211 corresponding to the fourth stress groove 1213 can be hollowed out, thereby significantly weakening the structural strength of the bottom of the installation groove 1211 at and near the fourth stress groove 1213. Based on this, stress can be concentrated at and near the fourth stress groove 1213, and the bottom of the installation groove 1211 can be subjected to concentrated stress and generate concentrated strain at and near the fourth stress groove 1213, thereby facilitating the pressure sensor 20 to sensitively, reliably and effectively detect the strain amount and changes, and accurately identify and detect whether the user has pressed the front end of the shell 10.

[0108] Of course, in other possible implementations, the fourth stress groove 1213 may not be arranged to penetrate along the front-to-back direction, and this embodiment does not limit this.

[0109] See also Figure 8 In this embodiment, the fourth stress groove 1213 is formed extending along the left-right direction.

[0110] By extending the fourth stress groove 1213 in the left-right direction, the extension direction of the fourth stress groove 1213 can be intersected with or even perpendicular to the stress direction, which can relatively weaken the structural strength of the bottom of the mounting groove 1211 at and near the fourth stress groove 1213, and ensure the structural strength of the bottom of the mounting groove 1211 at the upper and lower sides of the fourth stress groove 1213. Based on this, the stress can be concentrated at and near the fourth stress groove 1213, and the bottom of the mounting groove 1211 can be subjected to concentrated stress to generate concentrated bending strain at and near the fourth stress groove 1213, thereby facilitating the pressure sensor 20 to sensitively, reliably and effectively detect the strain amount and change, and accurately identify and detect "whether the user has pressed the front end of the shell 10".

[0111] Of course, in other possible implementations, the fourth stress groove 1213 may be set to be through or non-through along its extension direction; and / or, the fourth stress groove 1213 may be formed by extending along other directions; and / or, a plurality of fourth stress grooves 1213 may be provided, and the plurality of fourth stress grooves 1213 are cross-arranged; this embodiment does not impose any restrictions on this.

[0112] Example 7

[0113] See also Figure 4 In this embodiment, a curved surface 1222 is provided on the front side of the load-bearing member 122 .

[0114] By adopting the above-mentioned solution, when the user holds the dictionary pen and presses the front end of the dictionary pen shell 10 on the scanned content, the curved surface 1222 on the front side of the load-bearing member 122 can smoothly contact the scanned content. Based on this, the risk of the scanned content being scratched or worn by the load-bearing member 122 can be effectively reduced, thereby ensuring and improving the performance of the scanning pen.
