Description

Technical Field

[0001] The utility model relates to the technical field of learning supplies, in particular to a sitting posture correction device. Background Art

[0002] A sitting posture corrector is an auxiliary device specially designed to help students maintain a good sitting posture. With the habit of modern students sitting for long periods of time, the accompanying bad sitting posture problem is becoming increasingly prominent, which not only causes body posture deformation, but also may cause pain in the lumbar spine, cervical spine and other parts, and even affect normal growth and development in severe cases. Therefore, using a reasonable and effective sitting posture corrector is crucial to cultivate students' good sitting habits.

[0003] The sitting posture corrector in the related art includes a desktop board and a correction bracket. The desktop board provides a writing or reading surface for students, while the correction bracket is installed on the outer edge of the desktop board and is perpendicular to the desktop board. When in use, the correction bracket is set in front of the student's upper body to prevent excessive forward leaning, thereby helping students maintain a correct upper body posture and avoid long-term hunched or hunched sitting posture.

[0004] This design of sitting posture corrector has a good sitting posture correction effect, but it also has some shortcomings. First, since the correction bracket is fixedly connected to the desktop panel, the flexibility of the device is reduced to a certain extent. Sometimes students do not need to use the correction bracket, but simply use the desktop for writing or reading. At this time, the presence of the correction bracket will cause a certain degree of space and visual interference. However, since the two are fixed together, it is not easy to remove the correction bracket or change its shape. Secondly, this design is also insufficient in portability. Since the correction bracket is fixed vertically to the desktop panel, the entire device takes up a large space when stored or carried, which brings inconvenience to the user. At the same time, during transportation, the correction bracket is also easily damaged by collision. Utility Model Content

[0070] The sitting posture correction device according to an embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0071] Reference Figures 1 to 9 As shown, the sitting posture correction device provided according to an embodiment of the utility model includes a desktop panel 10 and a correction bracket 20.

[0072] Specifically, the outer edge of the desktop panel 10 has a pivot interface H10. The desktop panel 10 can be made of a solid plastic material, and the size of the panel can be appropriately designed according to the usage scenario, for example, about 60cm×40cm. The pivot interface H10 on the desktop panel 10 is used to correct the rotation installation of the bracket 20.

[0073] The correction bracket 20 is used to correct the sitting posture of the user. The correction bracket 20 comprises a base 201 and a bracket 202. The base 201 is pivotally arranged in the pivot interface H10 around a horizontal axis. A limiting structure is arranged between the base 201 and the side wall of the pivot interface H10.

[0074] The base 201 is usually made of high-strength plastic or metal material, such as aluminum alloy. The base 201 is pivotally assembled in the pivot interface H10, so that the correction bracket 20 can rotate around the horizontal axis. The bracket 202 is used to prevent the student's upper body from leaning forward when in use, and plays a corrective role in maintaining the sitting posture. The bracket 202 can adopt various bracket structures in the prior art, such as a "human" shape and other structural designs.

[0075] The limiting structure is configured to limit the correction bracket 20 to different positions, and the different positions include at least a first position and a second position. When the correction bracket 20 is located at the first position, the correction bracket 20 is located above the desktop panel 10 and is substantially perpendicular to the desktop panel 10; when the correction bracket 20 is located at the second position, the correction bracket 20 is located below the desktop panel 10 and forms a predetermined angle with the desktop panel 10.

[0076] As for the limiting structure, its function is to accurately limit the correction bracket 20 to several different main use positions, so as to ensure a good correction effect and user experience.

[0077] When the sitting posture needs to be corrected, the correction bracket 20 is first rotated and erected, and the limiting structure is used to make it in the first position. At this time, the bracket 202 is vertically arranged above the desktop 10 and is substantially perpendicular to the desktop, forming an effective barrier to prevent students from leaning forward and hunching over. When students sit at the desk to write or read, the bracket 202 can naturally limit the degree of forward leaning of the upper body, thereby achieving the purpose of correcting a bad sitting posture.

[0078] When the correction function is not needed, the correction bracket 20 only needs to be easily rotated to the second position and positioned through the limiting structure. At this time, the bracket 202 will be stored under the desktop panel 10, presenting a certain preset angle with the desktop, and will not cause obstruction or blockage to the space above the desktop panel 10, thereby avoiding space occupation and visual interference in the vertical state.

[0079] It should be noted that the limiting structure can adopt various common limiting mechanism forms such as protrusions and grooves, teeth and tooth grooves, elastic limiting structure, etc., which can be selected according to actual conditions, as long as the correction bracket 20 can be limited to the required use position more accurately.

[0080] According to the sitting posture correction device provided by the embodiment of the utility model, through the pivot connection between the base 201 of the correction bracket 20 and the outer edge of the desktop board 10, the correction bracket 20 can be flexibly switched and freely positioned in different positions. When the correction bracket 20 is in the first position, it can be vertically set above the desktop board 10, and is roughly vertical to the desktop. At this time, it can effectively prevent the student's upper body from leaning forward and assist in correcting a bad sitting posture. When the correction function is not needed, the correction bracket 20 can be flexibly rotated to the second position, lying under the desktop board 10, maintaining a certain angle with the desktop, avoiding space occupation and visual interference in a completely vertical state. This adjustable design not only improves the flexibility and portability of the correction device, but also enhances its applicable scenarios, allowing students to decide whether to enable the correction function according to specific needs. At the same time, the limiting structure between the pivot interface H10 and the base 201 can ensure that the correction bracket 20 is accurately positioned at different positions, further ensuring the correction effect and user experience.

[0081] It should be noted that when the correction bracket 20 is located in the second position, the correction bracket 20 is located below the desktop panel 10 and is at a predetermined angle with the desktop panel 10. Preferably, the predetermined angle is ninety degrees. That is, the correction bracket 20 is located below the desktop panel 10 and is substantially perpendicular to the desktop panel 10. In this form, when the correction function is not needed, it will hardly interfere with the user's space and viewing angle. Of course, the predetermined angle can also be other angles, such as one hundred and twenty degrees greater than ninety degrees, etc.

[0082] Reference Figure 3 As shown, in one embodiment of the utility model, the different positions also include a third position. When the correction bracket 20 is located at the third position, the correction bracket 20 is located above the desktop panel 10 and is in contact with the bottom surface of the desktop panel 10. In this state, the volume and space occupied by the entire correction device are minimized, making it convenient to carry and store.

[0083] When the device needs to be carried or stored for a long time, the correction bracket 20 can be rotated to the third position, and the limiting structure can be used to firmly position it in a folded state that fits the desktop panel 10. This compact storage form greatly reduces the volume and size of the entire correction device, making it very convenient to carry and store. In addition, in this folded state, since the bracket 202 is against the bottom of the desktop panel 10, it is not easy to be damaged even if it is squeezed during transportation and carrying, thus avoiding the problem that when the bracket 202 is in a vertical state with the desktop panel 10, it is easy to be squeezed and cause damage to the connection between the bracket 202 and the desktop panel 10.

[0084] The design of the third position not only makes the sitting posture correction device flexible and practical, but also greatly enhances its portability and storage convenience. It is compact and occupies very little space, which can greatly reduce the burden when it needs to be carried or stored for a long time, improves the reliability of storage, and prevents damage. This compact storage method improves the use scenario and user experience of the device.

[0085] Reference Figures 4 to 7 As shown, in one embodiment of the utility model, the limiting structure includes an elastic positioning part and a plurality of positioning grooves H11, and the elastic positioning part is arranged on the base 201. The elastic positioning part refers to a protrusion arranged on the base 201, which has a certain elastic deformation ability and can produce temporary displacement when subjected to force. The elastic positioning part can be a structure integrally formed with the base 201, or a split metal structure, etc., and its shape can be designed to be cylindrical, spherical, conical or other appropriate shapes.

[0086] A plurality of positioning grooves H11 are arranged on the desktop board 10 at intervals in the circumferential direction around the horizontal axis, and each positioning groove H11 corresponds to one of the different positions. For example, there are three positioning grooves H11, and the positions of the three positioning grooves H11 correspond to the first position, the second position, and the third position of the correction bracket 20, respectively.

[0087] The positioning groove H11 can be a concave structure, designed to be rectangular, semicircular or other shapes that match the elastic positioning part, and its internal size needs to be slightly larger than the size of the elastic positioning part itself, so as to accommodate the insertion of the elastic positioning part. When the elastic positioning part is inserted into the positioning groove H11, the correction bracket 20 can be accurately limited to the corresponding position to achieve accurate positioning.

[0088] When the correction bracket 20 rotates, the elastic positioning part rotates with the base 201 and selectively engages with one of the plurality of positioning slots H11 to limit the correction bracket 20 to the corresponding position. In other words, when the correction bracket 20 rotates, the base 201 also rotates, thereby driving the elastic positioning part to rotate in the circumferential direction. When the elastic positioning part rotates to the position of a certain positioning slot H11, it will engage into the positioning slot H11 due to its own elastic deformation.

[0089] In this embodiment, the above-mentioned limiting structure is adopted. On the one hand, no additional complex mechanism is required, and its overall size and space occupancy are relatively compact, and the installation and disassembly of each component are relatively simple, which is conducive to reducing the cost and difficulty of manufacturing and assembly. On the other hand, the positioning groove H11 has good design flexibility, and the number and distribution position can be freely set according to actual needs, so as to better meet the precise positioning requirements for different positions in different scenarios. On the other hand, the limiting structure is simple and convenient to use. The correction bracket 20 only needs to be easily rotated to the desired position to be accurately positioned, without the need for other cumbersome adjustment operations, which reduces the complexity of use and improves the user experience.

[0090] Reference Figures 4 to 6 As shown, in one embodiment of the present invention, the pivot interface H10 is a U-shaped opening, and the opening of the U-shaped opening is open to the outside of the desktop board 10. The design of the U-shaped opening is conducive to the assembly and disassembly of the base 201, and is also conducive to the rotation of the correction bracket 20 from the first position to the second position.

[0091] The two side walls of the U-shaped opening have a shaft portion 101, the axis of the shaft portion 101 extends along the horizontal direction, and pivot holes H20 are provided at both ends of the base 201, and the pivot holes H20 correspond to the shaft portion 101 one by one and are pivotally matched.

[0092] That is, the pivot hole H20 at one end of the base 201 is sleeved with the shaft portion 101 on one side, and the pivot hole H20 at the other end of the base 201 is also sleeved with the shaft portion 101 on the opposite side. The base 201 can rotate freely around the shaft portion 101, achieving a stable and reliable pivot connection. This connection structure is not only easy to assemble, but also the fit between the base 201 and the shaft portion 101 is tight and reliable, which can ensure the smooth rotation of the correction bracket 20 when in use.

[0093] It can be understood that a plurality of the positioning grooves H11 can be arranged on the side wall of the rotating shaft portion 101 or the U-shaped opening, and the elastic positioning portion is arranged at the end of the base 201. In this way, a limiting structure can be formed between one end or both ends of the base 201 and the U-shaped opening. The limiting structure arranged at the end of the base 201 can improve the limiting stability of the correction bracket 20, especially when the limiting structures are formed at both ends of the base 201, it can ensure that the correction bracket 20 maintains good stability after being rotated to the desired position.

[0094] Preferably, the side wall opposite to the opening in the U-shaped opening can serve as a limiting wall. When the correction bracket 20 rotates to the first position, on the one hand, the correction bracket 20 is limited to the first position by the limiting structure, and on the other hand, the correction bracket 20 is abutted against the above-mentioned limiting wall. The limiting wall can be used to limit the correction bracket 20 from continuing to rotate toward the inside of the desktop panel 10, thereby maintaining the correction bracket 20 in a reliable vertical state, thereby playing an effective and reliable blocking and correction role.

[0095] Reference Figures 4 to 6 As shown, in one embodiment of the present invention, the end of the shaft portion 101 extends into the pivot hole H20, a plurality of positioning grooves H11 are provided on the end surface of the end of the shaft portion 101, the base 201 is a hollow structure, and the elastic positioning portion is provided in the end of the base.

[0096] In this embodiment, the positioning groove H11 is provided on the end surface of the shaft portion 101 extending into the pivot hole H20. On the one hand, the limiting structure can be hidden inside the base 201 to ensure its reliability and improve safety. On the other hand, the end surfaces of the base 201 and the two side walls of the U-shaped opening can be fitted together, making the rotation of the base 201 more stable and reliable.

[0097] It can be understood that in other embodiments, the positioning groove H11 can also be arranged on the outer peripheral wall of the rotating shaft portion 101, and multiple positioning grooves H11 are arranged at circumferential intervals along the rotating shaft portion 101. Correspondingly, the elastic positioning portion can be arranged on the inner wall of the pivot hole H20. In this way, the elastic positioning portion and the positioning groove H11 can be selectively engaged to achieve a limiting effect.

[0098] Reference Figures 4 to 7 As shown, in one embodiment of the utility model, the positioning groove H11 is a strip groove extending radially along the rotating shaft portion 101, and the elastic positioning portion includes an elastic support foot portion 2011a and a strip positioning portion 2011b, one end of the elastic support foot portion 2011a is fixed on the base, and the strip positioning portion 2011b is formed on the elastic support foot portion 2011a and is adapted to the strip groove.

[0099] In this embodiment, the positioning groove H11 adopts a strip groove structure extending radially along the rotating shaft portion 101. These strip grooves are in the form of narrow and long strip grooves, and the cross-sectional shape of the strip grooves can be semicircular arc-shaped, etc., and the size needs to match the strip positioning portion 2011b of the elastic positioning portion. The strip groove design arranged in the radial direction enables the elastic positioning portion to obtain a larger force-bearing area when it is inserted, thereby improving the reliability and accuracy of the limit, and also facilitates the selection of the number of positioning grooves H11, so that the correction bracket 20 can be accurately positioned at more angles.

[0100] At the same time, the elastic positioning part adopts an elastic foot part 2011a, and the elastic foot part 2011a can be made of a metal strip or a plastic strip with a certain elasticity. When it is a plastic strip, it can be formed with the base 201 by an integral injection molding process. The free end of the elastic foot is located in the inner cavity of the base 201 and is fixedly connected with a strip-shaped positioning part 2011b. The outer dimensions of the strip-shaped positioning part 2011b match those of the strip-shaped groove. The elastic positioning part adopting this structure utilizes the elasticity of the elastic foot part 2011a to improve the elastic engagement between the elastic positioning part and the positioning groove H11, ensuring that the limiting is reliable and stable. At the same time, it also ensures that the elastic positioning part can smoothly escape from the positioning groove H11 when rotating, ensuring its convenient use.

[0101] Reference Figure 6 As shown, in some embodiments of the present invention, the base 201 includes a first shell portion 201a and a second shell portion 201b, the first shell portion 201a is provided with a first half hole H201 at both ends, and the second shell portion 201b is provided with a second half hole H202 at both ends.

[0102] The first shell portion 201a is connected to the second shell portion via a detachable connecting piece, the first half hole H201 and the second half hole H202 correspond one to one and are combined to form the pivot hole H20. During assembly, the first shell portion 201a and the second shell portion 201b can be buckled into each other and then connected via detachable connecting pieces such as screws to achieve assembly.

[0103] In this embodiment, the base 201 is a structure composed of a first shell 201a and a second shell 201b connected in a detachable manner. This design not only improves the convenience of manufacturing, processing and assembly, but also provides great convenience for subsequent disassembly and maintenance.

[0104] Exemplarily, the first shell 201a and the second shell 201b are both hollow semi-tubular structures, and the first half hole H201 and the second half hole H202 are respectively opened on the end surfaces at both ends. The inner diameters of the first half hole H201 and the second half hole H202 are the same, and when they are aligned and combined with each other, they can form a complete pivot hole H20 for accommodating the shaft portion 101. A number of threaded holes are also opened on the first shell 201a and the second shell 201b for installing detachable connecting parts, such as screws, bolts, etc. During assembly, the first shell 201a and the second shell 201b are first buckled up and down to combine the first half hole H201 and the second half hole H202 of the two into a complete pivot hole H20. Then screw the screws into the threaded holes and tighten them, so that the first shell 201a and the second shell 201b are tightly engaged in the axial direction and assembled into a whole base 201.

[0105] Reference Figures 4 to 6As shown, in one embodiment of the utility model, a stop head 101a is formed at the end of the shaft portion 101, the diameter of the stop head 101a is larger than the diameter of the shaft portion 101, and is stopped on the inner side of the end wall of the first shell portion 201a and the second shell portion 201b, and the positioning groove H11 is located on the end surface of the stop head 101a away from the shaft portion 101.

[0106] After the first shell 201a and the second shell 201b are buckled and assembled, the stopper head 101a of the rotating shaft portion 101 can be restricted inside the two ends of the base 201, thus improving the reliability between the base 201 and the rotating shaft portion 101 after assembly, and the base 201 is not easily separated from the rotating shaft portion 101. In addition, since the diameter of the stopper head 101a is larger than the diameter of the rotating shaft portion 101, it is more convenient and effective to arrange the positioning groove H11 on the end surface of the stopper head 101a. For example, the size of the positioning groove H11 can be designed to be larger, so that the limiting effect is more reliable and stable.

[0107] Reference Figures 8 to 9 As shown, in some embodiments of the utility model, a receiving groove is provided on the desktop panel 10, and the sitting posture correction device also includes a rotating bracket 30, which is pivotally provided on the desktop panel 10 and can be switched between an open state and a folded state. The rotating bracket 30 is made of plastic parts, and can also be made of metal parts. The rotating bracket 30 can adopt various structural shapes as long as it can achieve the support function for the electronic device. In order to reduce the volume of the rotating bracket 30 in the folded state, the rotating bracket 30 is usually constructed as a sheet-like structure.

[0108] When the rotating bracket 30 is in the open state, the rotating bracket 30 is suitable for carrying the electronic device so that the electronic device forms a predetermined viewing angle, and when the rotating bracket 30 is in the folded state, the rotating bracket 30 is folded into the receiving groove. Exemplarily, in the folded state, the rotating bracket 30 is parallel to or overlaps with the desktop panel 10. In the open state, the rotating bracket 30 forms an angle of 90 to 120° with the desktop panel 10, which is convenient for supporting the electronic device at a suitable viewing angle.

[0109] During use, if you need to use electronic devices such as tablet computers and mobile phones for study or work, you can open the rotating bracket 30 located on the front of the desktop panel 10. Opening method: Rotate the rotating bracket 30 in the receiving slot upward by a certain angle to a fully open state.

[0110] After the rotating bracket 30 is fully opened, electronic devices such as tablet computers and mobile phones can be placed on the desktop 10 and leaned against the rotating bracket 30 to form a desired viewing angle of the electronic device. After use, after removing the electronic device, the rotating bracket 30 is rotated downward and retracted into the receiving slot for storage.

[0111] In this embodiment, a rotating bracket 30 is arranged on the desktop panel 10, so as to realize the combination of the correction function and the support of the electronic device. A receiving groove is provided on the desktop panel 10, and the rotating bracket 30 can be rotated to a folded state and stored in the receiving groove, which effectively saves desktop space and improves the convenience of use. When it is necessary to use electronic devices such as tablet computers and mobile phones, it is only necessary to turn the rotating bracket 30 to an open state, and then the electronic device can be placed on it, without the need for an additional bracket, which is very convenient to use and has low user cost. In addition, the integrated design of the rotating bracket 30 and the desktop panel 10 not only avoids the hidden danger of the electronic device bracket possibly tipping over, but also enhances the user experience. At the same time, the overall integrated design makes the device compact in structure, beautiful and elegant, and suitable for use in various scenarios such as home and office.

[0112] Reference Fig. 9 As shown, in one embodiment of the present invention, the receiving groove includes a first receiving groove H12, and the rotating bracket 30 includes a supporting member 301, which is arranged in the first receiving groove H12 and is pivotally connected to the desktop panel 10 and can rotate between a fourth position and a fifth position.

[0113] When the supporting member 301 is located at the fourth position, the supporting member 301 is located in the first receiving groove H12. When the supporting member 301 rotates to the fifth position, a first angle is formed between the supporting member 301 and the desktop panel 10 so that the electronic device can lean on the supporting member 301.

[0114] In this embodiment, the rotating bracket 30 includes a supporting member 301, which is pivotally connected to the first receiving groove H12 on the desktop panel 10 and can be rotated between the fourth position and the fifth position. When the supporting member 301 is in the fourth position, i.e., the fully stored state, the top surface of the desktop panel 10 will be restored to a flat state, and will not cause any occupation of the desktop panel 10. When it is necessary to use electronic devices such as tablet computers and mobile phones, it is only necessary to rotate the supporting member 301 to turn it to the fifth position. In the fifth position, the supporting member 301 will rise on the desktop panel 10 at a certain angle, providing a reasonable tilting viewing angle for the electronic device. The user only needs to lean the entire electronic device against the supporting member 301 to obtain a viewing angle.

[0115] In one embodiment of the present invention, the rotating bracket 30 further includes a stopper 302 , which is disposed on the desktop panel 10 to prevent the electronic device from sliding when the electronic device leans on the supporting member 301 , so that the electronic device maintains a predetermined viewing angle.

[0116] In this embodiment, the rotating bracket 30 also includes a stopper 302. The stopper 302 is a small-sized stopper, which is arranged adjacent to the first receiving groove H12. When the supporting member 301 rotates from the fourth position to the fifth position, an electronic device such as a mobile phone, a tablet, etc. can be placed between the supporting member 301 and the stopper 302, and the back of the electronic device is leaned against the supporting member 301, and the bottom edge of the electronic device is leaned against the stopper 302. In this way, under the stopping effect of the stopper 302 on the electronic device, the electronic device is prevented from slipping during the use of the supporting member 301 at an inclined viewing angle. As long as the electronic device is placed between the stopper 302 and the supporting member 301, the position of the device can be firmly fixed, so that the viewing angle of the electronic device remains unchanged.

[0117] By adding the design of the stopper 302, the actual usage scenario is fully taken into consideration, which plays an important role in preventing the electronic device from slipping and maintaining a stable viewing angle, thereby greatly improving the user experience.

[0118] Preferably, when the supporting member 301 is located at the fifth position, the height of the stopping member 302 is smaller than the height of the supporting member 301 , and a loading interval for placing the electronic device is defined between the supporting member 301 and the stopping member 302 .

[0119] That is, when the rotating bracket 30 is in use, the stopper 302 protrudes from the desktop panel 10 at a relatively small height, while the supporting member 301 has a relatively high height dimension. This arrangement enables the supporting member 301 to reliably support the electronic device and keep it at a suitable viewing angle. At the same time, the stopper 302 plays a stopping role to keep the electronic device stable while reducing the blocking of the electronic device by the stopper 302, thereby maintaining a better viewing effect.

[0120] In addition, it should be noted that a moderate spacing space (i.e., loading spacing) is formed between the stopper 302 and the supporting member 301. This spacing space serves as a specific loading area for placing electronic devices. Users only need to slide mobile phones, tablets and other devices naturally along the supporting member 301 to accurately place the devices in this loading area, which is convenient for users to quickly, easily and conveniently place electronic devices when using them.

[0121] The size of the loading spacing is usually smaller than the width of the electronic device and larger than the thickness of the electronic device. In this way, after the electronic device is placed, it can form a tilted state, thereby meeting the user's reasonable needs for viewing angle.

[0122] In some embodiments of the present invention, the receiving groove includes a second receiving groove H13 , the stopping member 302 is disposed in the second receiving groove H13 and is pivotally connected to the desktop panel 10 and is rotatable between the sixth position and the seventh position.

[0123] When the stopping member 302 is located at the sixth position, the stopping member 302 is located in the second receiving groove H13. When the stopping member 302 rotates to the seventh position and the supporting member 301 is located at the fifth position, a second angle is formed between the stopping member 302 and the desktop panel 10 and the loading spacing is limited between the stopping member 302 and the supporting member 301.

[0124] In this embodiment, the stopper 302 is also designed to be a pivotable structure so that it can rotate freely between the sixth position and the seventh position. When the stopper 302 is in the sixth position, it will be completely received in the second receiving groove H13, so that the desktop panel 10 remains in a complete and flat state. When the electronic device needs to be used, the supporting member 301 is first rotated out of the first receiving groove H12 to the fifth position to form a predetermined tilt angle, and then the stopper 302 is rotated out of the second receiving groove H13 to the seventh position. At this time, the stopper 302 will protrude above the desktop panel 10 at an appropriate height and angle, and the above-mentioned loading spacing is formed between the stopper 302 and the inclined surface of the supporting member 301. The user only needs to slide the electronic device into this loading spacing at an appropriate angle.

[0125] The stopper 302 also adopts a pivoting design, which further improves the simplicity and practicality of the product while maintaining the function of preventing slippage. When not in use, the supporting member 301 and the stopper 302 can be completely stored in the first receiving groove H12 and the second receiving groove H13 respectively, and will not occupy any desktop space. This storable and extendable design is easy to operate and greatly improves the practicality and portability of the product.

[0126] It can be understood that in other embodiments of the present invention, the stop member 302 can also be a fixed structure. For example, the stop member 302 is formed as a protrusion slightly protruding from the top surface of the desktop panel 10. The protrusion can be an integrally molded structure with the desktop panel 10, or it can be a split structural member that is post-installed and fixed by means of snap-fit, plug-in, threaded connection, bonding, etc.

[0127] In some embodiments, the correction bracket 20 is a telescopic correction bracket with adjustable height, so as to meet the different usage needs of users.
