[0047] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention. All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.
[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0049] In order to solve the problem that the current movable study table needs to be equipped with a separate desk lamp during use, which causes inconvenience in use, the present invention provides a movable study table, see Figure 1 As shown, the movable study table includes a movable desktop 1, a clamping structure 2 and a desk lamp; wherein the movable desktop 1 is an ergonomic desktop structure, and the movable desktop 1 is connected to the clamping structure 2, and the movable desktop 1 is connected to the desktop of an ordinary desk through the clamping structure 2, thereby improving the desktop of the ordinary desk into an ergonomic structure.
[0050] To facilitate user use, the movable study table provided in the present application also includes a desk lamp, which includes a lamp head 3 for lighting and a bracket 4 connected to the lamp head 3, through which the lamp head 3 is supported and fixed. At the same time, the present application preferably connects the bracket 4 to the clamping structure 2, so as to save space while expanding the function of the movable study table.
[0051] The movable study table provided by the present invention expands the function of the movable study table by providing a desk lamp, thereby avoiding the need to separately equip the movable study table with a desk lamp when using the movable study table, thereby facilitating use; at the same time, the bracket 4 is connected to the clamping structure 2, thereby saving space and the use area of the movable study table, and also improving the stability of the desk lamp structure, thereby preventing the desk lamp from slipping during use.
[0052] The movable desktop 1 includes a desktop body 11 and an arm rest 12; the desktop body 11 is a plate-like structure and is located in the middle of the desktop; there are two arm rests 12, which are connected to both sides of the desktop body 11 in a downwardly inclined state, and are used to support the two arms of the user; the use sides of the two arm rests 12 and the use side of the desktop body 11 together form an arc-shaped structure, and the use side of the desktop body 11 forms a concave structure in the direction away from the user.
[0053] In the present application, arm rests 12 for supporting the arms are arranged on both sides of the desktop body 11, and the two arm rests 12 are further arranged to be connected to the two sides of the desktop body 11 in a downwardly inclined state. Arranging the two arm rests 12 to be connected to the two sides of the desktop body 11 in a downwardly inclined state specifically means that the two arm rests 12 are respectively connected to the two sides of the desktop body 11, and the height of the two arm rests 12 away from the desktop body 11 is lower than the height of the two arm rests 12 connected to the desktop body 11.
[0054] By setting the two arm rests 12 in a downwardly inclined shape, when the user puts his or her arms on the arm rests 12, the arm near the elbow is placed on the side of the arm rest 12 away from the desk body 11, and the arm near the wrist is placed on the side of the arm rest 12 close to the desk body 11. Since the height of the side of the arm rest 12 away from the desk body 11 is lower than the height of the side of the arm rest 12 close to the desk body 11, when the user's arm is supported by the arm rest 12, the height of the side of the user's arm near the elbow is lower than the height of the side near the wrist, so that the arm is in a state of slightly drooping elbow. This state is not only more ergonomic, but also can concentrate most of the gravity on the arm on the elbow, thereby reducing the pressure between the muscles under the arm and the arm rest 12, and then alleviating the squeezing force on the muscles under the arm during writing, thereby improving the user's comfort during writing and improving the writing effect.
[0055] In order to further improve the user's comfort, according to ergonomics, the use side of the two armrests 12 and the use side of the desktop body 11 in this application jointly form an arc structure, and the use side of the desktop body 11 forms a concave structure in the direction away from the user. The use side of the armrest 12 specifically refers to the side of the armrest 12 close to the user when the desktop is in use; similarly, the use side of the desktop body 11 specifically refers to the side of the desktop body 11 close to the user when the desktop is in use. When the use side of the two armrests 12 and the use side of the desktop body 11 jointly form an arc structure, and the use side of the desktop body 11 forms a concave structure in the direction away from the user, after the user's arm is placed on the armrest 12, an eight-shaped structure is formed between the two arms, so that the posture of the eight-shaped structure is more ergonomic, so that the arm can be completely placed on the armrest 12, and under the support of the armrest 12, the arm is in a relatively relaxed state, thereby improving the comfort during use and effectively relieving the user's fatigue. The preferred desktop body 11 of this application and the armrests 12 on both sides together form a scallop-like shape.
[0056] In order to ensure the comfort of the user during use, the present application preferably sets the downward inclination angle of the arm rest 12 in the range of 4° to 10°, and further preferably sets the downward inclination angle of the arm rest 12 to 5.5°, on the one hand, to avoid the arm rest 12 from sliding off easily due to the downward inclination angle being too large, and on the other hand, to avoid the arm rest 12 from being too small to effectively relieve the squeezing of the muscles under the arm. The downward inclination angle of the arm rest 12 in the present application specifically refers to the angle between the line connecting the highest point and the lowest point on the arm rest 12 and the horizontal line when the desktop body 11 is in a horizontal state.
[0057] The material of the armrest 12 can be the same as or different from that of the desktop body 11. In order to take into account both the mechanical strength and the comfort of use of the armrest 12, see Figure 2 As shown, the arm rest 12 of the present application preferably includes a steel plate 121 and a covering layer 122, and the steel plate 121 further includes a supporting portion 1211 and a connecting end 1212, wherein the supporting portion 1211 is used to support the user's arm, and the covering layer 122 is covered on the outer side of the supporting portion 1211; the connecting end 1212 is connected to the desktop body 11.
[0058] The present application preferably uses a flexible material for the covering layer 122, and further preferably uses a flexible material selected from a group consisting of a foamed flexible material, plastic, rubber, silicone, and latex, so that the user's arm is in direct contact with the flexible material, further alleviating the squeezing of the armrest 12 on the muscles under the arm. The steel plate 121 may be a common steel plate, and the specific shape, size, and thickness of the steel plate 121 may be determined according to requirements; the present application preferably uses a spring steel plate for the steel plate 121. The use of a spring steel plate is beneficial to increasing the resilience of the armrest 12 and preventing the armrest 12 from deforming, thereby improving the comfort of use of the armrest 12 and extending the service life of the armrest 12.
[0059] In order to facilitate the connection of the armrest 12 with the desktop body 11, the present application preferably comprises an upper desktop body and a lower desktop body 111 connected to each other, and the connection end 1212 is embedded between the upper desktop body and the lower desktop body 111. The connection method between the upper desktop body and the lower desktop body 111 can be fastener connection, bonding, snap connection, etc., and the present application does not limit the connection method between the upper desktop body and the lower desktop body 111.
[0060] Since the armrest 12 includes a steel plate 121 located in the middle and a covering layer 122 covering the outer side of the supporting portion 1211 in the steel plate 121, the desktop body 11 is configured as an upper desktop body and a lower desktop body 111 connected to each other, and the connecting end 1212 is embedded between the upper desktop body and the lower desktop body 111, so that the connecting end 1212 is located in the middle of the desktop body 11. On the one hand, it helps to increase the connection strength between the connecting end 1212 and the desktop body 11, thereby increasing the connection strength between the armrest 12 and the desktop body 11. On the other hand, the thickness of the covering layer 122 can be adjusted so that the upper surface of the covering layer 122 is flush with the upper surface of the desktop body 11, thereby improving the user's comfort and the aesthetics of the desktop.
[0061] Furthermore, in order to increase the connection strength between the desktop body 11 and the armrest 12, the present application further provides a protrusion 1111 on the lower desktop body 111, a groove matching the protrusion 1111 is provided on the upper desktop body, and a through hole 1213 matching the protrusion 1111 is provided on the connecting end 1212. When assembling the armrest 12 and the desktop body 11, first place the armrest 12 on the lower desktop body 111, place the protrusion 1111 on the lower desktop body 111 in the through hole 1213 on the connecting end 1212, then place the protrusion 1111 on the lower desktop body 111 in the corresponding groove on the upper desktop body, and then connect the upper desktop body and the lower desktop body 111, so that the connection between the armrest 12 and the desktop body 11 can be achieved. Since the protrusion 1111 on the lower desktop body 111 is located in the through hole 1213 on the connecting end 1212, the protrusion 1111 can limit the displacement of the connecting end 1212, thereby preventing the armrest 12 from being separated from the desktop body 11, and improving the connection strength between the armrest 12 and the desktop body 11. The number of protrusions on the lower desktop body 111 is at least one. In order to improve the stability of the connection, the present application preferably has three protrusions 1111 on the lower desktop body 111, and correspondingly, the number of grooves on the upper desktop body is three, and the number of through holes 1213 on the connecting end 1212 is also three.
[0062] The clamping structure 2 is used to connect the movable desktop 1 to the desktop of an ordinary desk, see Figure 3 , Figure 4 As shown, the clamping structure 2 in the present application includes a length adjustment structure 21, an angle adjustment structure 22 and a desktop sliding lock 23, wherein the length adjustment structure 21 is distributed in the horizontal direction and is used to be connected to the desktop of an ordinary desk; the length of the clamping structure 2 can be adjusted by the length adjustment structure 21, so that the clamping structure 2 can be connected to ordinary desks of various sizes and specifications, thereby expanding the use range of the movable study table; the angle adjustment structure 22 is used to adjust the inclination angle of the movable desktop 1 in the movable study table, and the front end of the length adjustment structure 21 is connected to the front end of the angle adjustment structure 22; the front end in the present application specifically refers to the end close to the user when the movable study table is installed on an ordinary desk; the desktop sliding lock 23 is connected to the movable desktop 1, the desktop sliding lock 23 is arranged on the angle adjustment structure 22, and the desktop sliding lock 23 is slidably connected to the angle adjustment structure 22, and the desktop sliding lock 23 slides on the angle adjustment structure 22, driving the movable desktop 1 to slide along the angle adjustment structure 22, thereby realizing the position adjustment of the movable desktop 1 in the front and rear directions.
[0063] At the same time, since the desktop sliding lock 23 is connected to the movable desktop 1, and the desktop sliding lock 23 is arranged on the angle adjustment structure 22, the movable desktop 1 is connected to the angle adjustment structure 22 through the desktop sliding lock 23, so that when the angle adjustment structure 22 adjusts the inclination angle, the inclination angle of the movable desktop 1 can be driven to change.
[0064] The desktop sliding lock 23 in the present application is equivalent to the desktop sliding structure. By setting the desktop sliding lock 13 on the angle adjustment structure 22, an integrated design of the desktop sliding structure and the angle adjustment structure 22 is realized, so that the clamping structure 2 can adjust the inclination angle of the movable desktop 1 while also being able to adjust the position of the movable desktop 1 in the front and rear directions, that is, the distance between the movable desktop 1 and the user.
[0065] During the use of the movable study table, first, according to the size of the desktop of the ordinary desk to be connected, the length of the clamping structure 2 is adjusted through the length adjustment structure 21, so that the length of the clamping structure 2 is adapted to the desktop size of the ordinary desk to be connected, and then the clamping bracket 4 is connected to the desktop of the ordinary desk through the length adjustment structure 21; then, according to the use requirements, the movable desktop 1 is adjusted to the required angle through the angle adjustment structure 22, and then the position of the movable desktop 1 in the front-to-back direction is further adjusted through the desktop sliding lock 23, so that the adjusted movable desktop 1 can meet the use requirements of the user; similarly, in the process of adjusting the movable desktop 1, the position of the movable desktop 1 in the front-to-back direction can also be adjusted through the desktop sliding lock 23, and then the inclination angle of the movable desktop 1 can be adjusted through the angle adjustment structure 22, or the two adjustment processes are performed alternately until the movable desktop 1 is adjusted to the position that meets the use requirements of the user.
[0066] To facilitate connecting the clamping structure 2 to the desktop of an ordinary desk, the length adjustment structure 21 in the present application includes a telescopic connecting member 211, and a first clamping member 212 and a second clamping member 213 respectively connected to the two ends of the telescopic connecting member 211. When connected to the desktop of an ordinary desk, the first clamping member 212 and the second clamping member 213 are respectively clamped at the two ends of the desktop of the ordinary desk.
[0067] The length of the telescopic connection member 211 is adjustable. By adjusting the length of the telescopic connection member 211, the distance between the first clamping member 112 and the second clamping member 113 is adjusted, so that the movable study table can be suitable for ordinary desks of various sizes.
[0068] Specifically, the telescopic connector 211 preferably includes two parallel mother rods.

By arranging the desktop sliding lock 23 and the first adjustment lock 224 in the first support rod 2221, the desktop sliding structure and the angle adjustment structure 22 can be integrated, which is conducive to simplifying the structure of the movable learning table.
[0075] In order to simultaneously set the desktop sliding lock 23 and the first adjustment lock 224 in the first support rod 2221, see Figure 5 As shown, in the present application, the first support rod 2221 is provided with a first groove 2223 adapted to the desktop sliding lock 23, and a second groove 2224 adapted to the first adjustment lock 224; the first groove 2223 is arranged on the inner side of the second groove 2224, and the opening direction of the first groove 2223 is upward, and the opening direction of the second groove 2224 is downward.

[0092] The light source is designed as a main lamp 33 and two auxiliary lamps 34, and the angles of the auxiliary lamp lighting parts 342 of the two auxiliary lamps 34 are adjustable. When the desk lamp is used, the light angles of the auxiliary lamp lighting parts 342 are adjusted by adjusting the angles of the auxiliary lamp lighting parts 342 on both sides. Combined with the light angle of the main lamp 33, the light emitted from the lamp head 3 has multiple emission directions, thereby avoiding the shadow of the object on the desktop after the object appears within the illumination range of the lamp head 3, thereby improving the lighting effect of the desk lamp.

[0098] To further enhance the lighting effect, see Figure 8 As shown, the present application preferably connects the main lamp 33 to the rotating part 341 via a first rotating shaft 331; wherein the first rotating shaft 331 is horizontally distributed along a direction perpendicular to the connecting surface; the connecting surface here still refers to the surface on the rotating part 341 that contacts the main lamp 33.
[0099] The first rotating shaft 331 is distributed along the horizontal direction, and the first rotating shaft 331 is perpendicular to the connecting surface; for the present application, it is preferred that the main lamp 33 and the auxiliary lamp 34 are both rectangular structures, and when the desk lamp is in use, the lengths of the main lamp 33 and the auxiliary lamp 34 are distributed along the left and right directions of the user. Therefore, in the present application, the first rotating shaft 331 is distributed along the length direction of the main lamp 33, that is, the first rotating shaft 331 is distributed along the left and right directions of the user; the main lamp 33 is rotatably connected to the rotating part 341 through the first rotating shaft 331, so that the rotating part 341 can rotate in the vertical direction, and when the rotating part 341 rotates, it drives the auxiliary lamp lighting part 342 to rotate in the vertical direction, thereby further adjusting the illumination angle of the auxiliary lamp 34 in the vertical direction, expanding the lighting range of the auxiliary lamp 34, so that the lamp head 3 can meet the different lighting needs of the user and expand the scope of use.
[0100] To facilitate connecting the main lamp 33 with the auxiliary lamp 34, see Fig.16 As shown, the main lamp 33 includes a main lamp housing 332, and the two end covers of the main lamp housing 332 are each provided with a third mounting hole 3321; the first rotating shaft 331 is distributed along the length direction of the main lamp 33; the rotating part 341 is provided with a fourth mounting hole 3415, and the first rotating shaft 331 is suitable for cooperating with the third mounting hole 3321 and the fourth mounting hole 3415 to realize the rotational connection between the main lamp 33 and the rotating part 341, thereby realizing the rotational connection between the main lamp 33 and the auxiliary lamp 34 in the vertical direction; in the specific connection process, the first rotating shaft 331 is sequentially passed through the fourth mounting hole 3415 and the third mounting hole 3321 to realize the rotational connection between the main lamp 33 and the rotating part 341.
[0101] In order to further improve the damping of the rotation between the main light 33 and the auxiliary light 34, a second rubber pad 3316 is arranged between the first rotating shaft 331 and the third mounting hole 3321 in the present application, and the second rubber pad 3316 is used to increase the resistance during the rotation process, so that the auxiliary light 34 can be stopped at any position during the rotation process; specifically, the second rubber pad 3316 is provided with a through hole adapted to the first rotating shaft 331, and the first rotating shaft 331 is passed through the through hole to realize the connection between the second rubber pad 3316 and the first rotating shaft 331.
[0102] In the present application, a second through hole 3317 is provided along the axis of the first rotating shaft 331 to facilitate laying of the electric wires through the second through hole 3317; in order to avoid damage to the electric wires during the rotation of the auxiliary lamp 34, the present application further limits the rotation angle of the rotating part 341 by providing a second limiting structure.
[0103] Specifically, the main lamp housing 332 in the present application further includes a second nut 3322 adapted to the first rotating shaft 331, and a second limiting structure 3323; the second nut 3322 and the second limiting structure 3323 are both arranged in the third mounting hole 3321; the first rotating shaft 331 passes through the fourth mounting hole 3415, the second rubber pad 3316, the second limiting structure 3323 in sequence;
[0104] 3323 is connected to the second nut 3322, and the second limiting structure 3323 is connected to the rotating part 341; a limiting protrusion 3324 is set on the second limiting structure 3323, and a limiting groove 3325 is set in the third mounting hole 3321; the limiting groove 3325 is suitable for cooperating with the limiting protrusion 3324 to realize the limitation of the rotation angle of the first rotating shaft 331.
[0105] When the rotating part 341 rotates, it drives the second limiting structure 3323 connected thereto to rotate; during the rotation of the second limiting structure 3323, the rotation range of the limiting protrusion 3324 is limited by the limiting groove 3325 and can only rotate within a certain range; therefore, the rotating part 341 connected to the second limiting structure 3323 can only rotate within a certain angle range, thereby limiting the rotation range of the rotating part 341 to avoid damage to the wires due to unlimited rotation of the rotating part 341 during use.
[0106] In the present application, a first clamping portion 3418 is provided on the side of the rotating portion 341 close to the main light 33, and a second clamping portion 3326 is provided on the side of the second limiting structure 3323 close to the rotating portion 341. The second clamping portion 3326 is suitable for cooperating with the first clamping portion 3418 to realize the connection between the second limiting structure 3323 and the rotating portion 341.
[0107] The main lamp 33 in the present application includes a main lamp housing 332 with a groove-type structure, and a main lamp lighting part 333 connected to the bottom of the main lamp housing 332; wherein the main lamp lighting part 333 and the auxiliary lamp lighting part 342 can be lighting structures of any structural form in the prior art, and the present application does not make specific limitations on the main lamp lighting part 333 and the auxiliary lamp lighting part 342.
[0108] Furthermore, in the present application, a reading tracking device 31 is provided in the lamp head 3, so that the reading position of the user on the book can be tracked and marked by the reading tracking device 31 during the reading process; the present application preferably sets the reading tracking device 31 in the main lamp 33; for the present application, after the main lamp housing 332 is connected to the main lamp lighting part 333, a storage space is enclosed between the main lamp housing 332 and the main lamp lighting part 333, and the present application sets the reading tracking device 31 in the storage space.
[0109] See also Fig. 9 , Fig.10 As shown, the reading tracking device 31 in the present application includes a light-emitting structure 311, a connecting structure 312 and a stepper motor 313; wherein the light-emitting structure 311 can emit light, and the reading or copying position is marked by irradiating the light on the corresponding position on the book; the connecting structure 312 is fixedly connected to the light-emitting structure 311; the connecting structure 312 is connected to the output shaft 3131 of the stepper motor 313, and the connecting structure 312 is driven to rotate by the stepper motor 313, thereby driving the light-emitting structure 311 to rotate, and while the light-emitting structure 311 rotates, the position of the light irradiated on the book by the light-emitting structure 311 changes, and the new reading or copying position is marked by the changed light position.
[0110] When using the reading tracking device 31, the position of the reading tracking device 31 is determined according to the book to be read or copied, so that the light emitted by the light-emitting structure 311 in the reading tracking device 31 can illuminate the corresponding position on the book; according to the needs of reading, the operation of the stepper motor 313 is controlled, and while the stepper motor 313 is running, the light irradiated onto the book by the light-emitting structure 311 is adjusted to the required position, and the reading position is marked to achieve tracking of the reading position.
[0111] Specifically, corresponding buttons may be provided on the reading tracking device 31, such as an up button (not shown in the figure) and a down button (not shown in the figure). The up button and the down button are both connected to the stepper motor 313 by signal or electrically connected. The operation of the stepper motor 313 is controlled by the up button and the down button to realize the upward and downward movement of the light on the book, thereby realizing the tracking of the reading position.
[0112] The reading tracking device 31 provided by the present invention drives the light emitting structure 311 to rotate through the stepping motor 313, so that the light emitted by the light emitting structure 311 moves on the book, thereby tracking the reading position through the moving light, thereby improving reading and learning efficiency.
[0113] To facilitate the control of the operation of the reading tracking device 31, the reading tracking device 31 in the present application may also include a control module, which is connected to the stepper motor 313 signal so that the operation of the stepper motor 313 can be controlled by the control module to improve the intelligence of the control; specifically, the present application preferably includes a single-chip microcomputer to simplify the control system.
[0114] See also Fig.17 As shown, the connection structure 312 in the present application includes an arc-shaped toothed ring 3121, and a first toothed structure is arranged on the inner wall of the toothed ring 3121; a gear shaft 3132 is fixedly connected to the output shaft 3131 of the stepper motor 313, and a second toothed structure is arranged on the outer side of the gear shaft 3132; the second toothed structure is suitable for cooperating with the first toothed structure to make the output shaft 3131 mesh with the toothed ring 3121.
[0115] When the reading tracking device 31 is used, the stepper motor 313 operates according to instructions, such as an upward movement instruction issued by the user through the upward movement button, or a downward movement instruction issued by the user through the downward movement button, and the output shaft 3131 rotates. The rotation direction of the output shaft 3131 is determined according to the corresponding instructions; because the output shaft 3131 is engaged with the gear ring 3121 through the gear shaft 3132, the output shaft 3131 rotates while driving the gear ring 3121 to rotate, and then drives the light-emitting structure 311 connected to the connecting structure 312 to rotate, so that the light emitted by the light-emitting structure 311 moves on the book, thereby realizing the tracking of the reading position.
[0116] To ensure that the light emitted from the reading tracking device 31 always shines on the book, as shown in Figure 17, the reading tracking device 31 provided in the present application also includes a first limiting structure 314 arranged adjacent to the connecting structure 312, and the first limiting structure 314 is used to limit the rotation angle range of the connecting structure 312.
[0117] Specifically, the first limiting structure 314 includes a first photoelectric sensing switch 3141 and a second photoelectric sensing switch 3142, and the connecting structure 312 includes a first light baffle 3122 and a second light baffle 3123, and the first light baffle 3122 and the second light baffle 3123 are respectively arranged at the two ends of the gear ring 3121; the first light baffle 3122 is adapted to the first photoelectric sensing switch 3141; the second light baffle 3123 is adapted to the second photoelectric sensing switch 3142; the first photoelectric sensing switch
[0118] 3141 and the second photoelectric sensor switch 3142 are both connected to the control module signal.
[0119] The position of the first photoelectric sensor switch 3141 is determined according to the upper limit position of the light emitting structure 311. When the light emitting structure 311 rotates to the upper limit position, the light emitted by the light emitting structure 311 just irradiates the highest position of the book. At this time, the first light baffle 3122 contacts the first photoelectric sensor switch 3141, and the control module controls the stepper motor 313 to stop running. The position of the second photoelectric sensor switch 3142 is determined according to the lower limit position of the light emitting structure 311. When the light emitting structure 311 rotates to the lower limit position, the light emitted by the light emitting structure 311 just irradiates the lowest position of the book. At this time, the second light baffle 3123 contacts the second photoelectric sensor switch 3142, and the control module controls the stepper motor 313 to stop running. It should be understood that, due to the different sizes of different books, the distance between the highest point and the lowest point of different books is different. Therefore, in order to make the reading tracking device 31 applicable to most books, in the present application, when the light emitting structure 311 is transferred to the upper limit position and the lower limit position, the light emitted does not necessarily correspond to the highest position and the lowest position on each book.
[0120] Furthermore, the reading tracking device 31 provided in the present application also includes a motor base 3133, which is fixedly connected to the stepper motor 313 and is used to fix the stepper motor 313; the first limiting structure 314 also includes a circuit board 3143, wherein the first photoelectric sensing switch 3141 and the second photoelectric sensing switch 3142 are both fixedly connected to the circuit board 3143; the output shaft 3131 passes through the motor base 3133, the circuit board 3143 and is fixedly connected to the gear shaft 3132 in sequence.
[0121] In order to improve the stability of the connecting structure 312, the connecting structure 312 is further rotatably connected to the motor base 3133 through a pin shaft 3124; specifically, one end of the pin shaft 3124 passes through the circuit board 3143 and is fixedly connected to the motor base 3133, and the other end is rotatably connected to the connecting structure 312, so that during the operation of the reading and tracking device 31, the connecting structure 312 can rotate around the pin shaft 3124 to prevent the connecting structure 312 from falling off.
[0122] The range of reading tracking is determined by the rotation angle of the gear ring 3121. The preferred rotation angle range of the gear ring 3121 is 75°. Within this rotation angle range, reading tracking of books of most sizes can be achieved. The light emitting structure 311 in the present application can be any structure that can emit light. The preferred light emitting structure 311 in the present application is selected from a light emitting diode and a straight line laser module.
[0123] See also Fig.11 As shown, after the reading tracking device 31 is placed in the main lamp 33, in order to facilitate the light emitted by the light emitting structure 311 to be emitted from the main lamp 33, the main lamp lighting part 333 is provided with a light-transmitting hole 3331 adapted to the light emitting structure 311. When the reading tracking device 31 is used, the light emitted by the light emitting structure 311 in the reading tracking device 31 is emitted through the light-transmitting hole 3331 and illuminates the book to track and mark the reading position.

A first light reflecting layer is arranged on the inner side of the top end of the main light lighting shell 3332. The present application preferably provides a light transmitting hole 3331 at the top end of the main light lighting shell 3332.
[0125] In order to prevent the light emitted by the light emitting structure 311 from being diffused by the light diffuser plate 3333, so that the area of light irradiated on the book is too large, and the reading position cannot be accurately marked, the present application preferably provides a transparent structure compatible with the light hole 3331 on the light diffuser plate 3333, that is, the light diffusion structure is not provided at the transparent structure, so that the light emitted by the light emitting structure 311 passes through the light hole 3331 and the transparent structure in turn and is emitted from the main light 33, and the emitted light does not pass through the light diffuser plate and is therefore not further diffused, so that the light emitted by the light emitting structure 311 is irradiated on the book in a point-like or straight-line structure, which effectively marks the reading position.
[0126] For ease of operation, the switch and other command buttons of the reading tracking device 31 can be integrated with the command buttons of the desk lamp; in addition, since the lamp head 3, as a light source, will also emit light after the desk lamp is turned on; in order to enable the light emitted by the light-emitting structure 311 to still be able to mark the reading position when the desk lamp is turned on, the present application preferably has a color of the light emitted by the light-emitting structure 311 that is different from the color of the light emitted by the lamp head 3; or the brightness of the light emitted by the light-emitting structure 311 is significantly brighter than the brightness of the light emitted by the lamp head 3.

By rotatably connecting the reading bookshelf 5 to the bracket 4, the angle of the reading bookshelf 5 can be adjusted by rotation during the reading process, so that the reading bookshelf 5 meets the user's usage needs. In addition, by making the height of the reading bookshelf 5 lower than the height of the lamp head 3, the position and height of the lamp head 3 and the reading bookshelf 5 can be adjusted by the bracket 4, so that the light emitted by the light emitting structure 311 in the lamp head 3 can be irradiated onto the books on the reading bookshelf 5, and the reading position is marked and tracked by the light irradiated onto the reading bookshelf 5 by the light emitting structure 311.
[0129] In order to facilitate the connection between the reading bookshelf 5 and the bracket 4, the bracket 4 in the present application includes a second horizontal support frame 44, one end of the second horizontal support frame 44 is rotatably connected to the vertical support frame 42, and the other end is rotatably connected to the reading bookshelf 5.

[0131] For ease of operation, the present application prefers that the damping direction of the third oil cylinder 46 is upward. On the one hand, it is convenient to support the reading bookshelf 5 through the damping of the third oil cylinder 46 to improve the stability of the movable study table structure; on the other hand, it reduces the difficulty of lifting the reading bookshelf 5 upward, thereby reducing the difficulty of adjusting the angle of the reading bookshelf 5.

[0133] The bracket 4 provided in the present application also includes a fourth oil cylinder 47, the bottom end of the fourth oil cylinder 47 is rotatably connected to the second connecting plate 424, and the piston rod of the fourth oil cylinder 47 is connected to the second connecting upper rod 4221; the present application preferably has the damping direction of the fourth oil cylinder 47 as downward, so that when the vertical support frame 42 is adjusted forward or backward, it is necessary to overcome the damping force of the fourth oil cylinder 47, and the fourth oil cylinder 47 can be used to keep the vertical support frame 42 balanced after being adjusted forward or backward, and at the same time, the difficulty of adjusting the vertical support frame 42 to the vertical direction can be reduced, which is convenient for operation.
[0134] The vertical support frame 42 in the present application is provided with the second connecting upper rod 4221 sleeved on the outside of the first connecting upper rod 4211, and the second connecting lower rod 4222 sleeved on the outside of the first connecting lower rod 4212, so as to improve the aesthetics of the bracket 4 on the one hand, and on the other hand, the connection point between the first connecting lower rod 4212 and the second connecting plate 424, the first connecting lower rod
[0135] The connection points between the bracket 4212 and the base 41, the connection points between the second connecting lower rod 4222 and the second connecting plate 424, and the connection points between the second connecting lower rod 4222 and the base 41 together form a parallelogram structure.

The parallelogram structure is used to keep the angle of the bracket 4 stable, thereby preventing the angle of the bracket 4 from changing automatically during use without adjustment by the user, thereby improving the stability and safety of the bracket 4 structure.
[0136] The first horizontal support frame 43 in the present application, through the third connecting rod 431, the fourth connecting rod 432, the first connecting plate 433 and the first dovetail connection part 32, together form a parallelogram structure; the second horizontal support frame 44, through the fifth connecting rod 441, the sixth connecting rod 442, the second connecting plate 424 and the second dovetail connection part, together form a parallelogram structure, through the parallelogram structure to make the angle of the lamp head 3 and the reading bookshelf 5 remain stable, and the angle will not change during use due to the weight of the lamp head 3 and the reading bookshelf 5 themselves.
[0137] The desk lamp provided by the present invention, through the multiple parallelogram structures in the bracket 4, on the one hand, enables the bracket 4 to adjust the height and angle of the lamp head 3 and the reading bookshelf 5, and on the other hand, enables the angle of the bracket 4 to remain unchanged after the adjustment is completed, thereby improving the stability of the structure.
[0138] The reading bookshelf 5 in the present application includes a book clamping device 51 and two book pressing devices 52 respectively arranged on both sides of the book clamping device 51; wherein the book clamping device 51 is used to clamp the spine of the book so as to fix the book; the book clamping device 51 is used to fix the opened pages of the book to prevent the pages from being closed again.
[0139] Specifically, participate Fig.12 , Fig.13 As shown, the book clamping device 51 in the present application includes a fixing portion 511, a first main body portion 512, a second main body portion 513 and a first adjustment structure 514; wherein the first main body portion 512 and the second main body portion 513 are relatively arranged at the front side of the fixing portion 511; the first main body portion 512 and the second main body portion 513 are slidably connected to the fixing portion 5111 through the first adjustment structure 514, so as to adjust the distance between the first main body portion 512 and the second main body portion 513 through the first adjustment structure 514. The front side here specifically refers to the side close to the user when the book clamping device 51 is in use.
[0140] When the book clamping device 51 is used specifically, the first adjusting structure 514 is used to first adjust the distance between the first main body 512 and the second main body 513 to be greater than the thickness of the book to be read, and then the spine of the book is placed between the first main body 512 and the second main body 513, and the first adjusting structure 514 is used to reduce the distance between the first main body 512 and the second main body 513, so that the first main body 512 and the second main body 513 are both in contact with the book, and the book is clamped, thereby fixing the book.
[0141] On the one hand, the book clamping device 51 forms a space for accommodating the spine of a book by arranging the first main body 512 and the second main body 513 to be slidably connected to the fixing part 511. The spine of the book is placed in the space, and the distance between the first main body 512 and the second main body 513 is adjusted by the first adjustment structure 514, so that the first main body 512 and the second main body 513 clamp the book to prevent the spine from bulging toward the side close to the reader, thereby preventing the opened pages from being closed, thereby improving the comfort of use. On the other hand, since the distance between the first main body 512 and the second main body 513 can be adjusted, the book clamping device provided by the present application can clamp books of different thicknesses and has a wide range of applications.
[0142] In order to adjust the distance between the first main body 512 and the second main body 513, the first adjustment structure 514 in the present application includes an adjustment rod 5141 and a gear adjustment structure fixedly connected to the adjustment rod 5141; the adjustment rod 5141 is rotatably connected to the fixed part 511; and the gear adjustment structure is slidably connected to the first main body 512 and the second main body 513 at the same time.
[0143] In order to improve the stability and aesthetics of the book clamping device structure, the present application preferably configures the fixing portion 511 to be a hollow structure, and the adjustment rod 5141 is arranged through the fixing portion 511 and is rotatably connected to the fixing portion 511; at the same time, the gear adjustment structure is arranged in the fixing portion 511, and the gear adjustment structure is slidably connected to both the first main body portion 512 and the second main body portion 513.
[0144] When it is necessary to adjust the distance between the first main body 512 and the second main body 513, rotate the adjusting rod 5141. When the adjusting rod 5141 rotates, it drives the gear adjustment structure to move, and then the action of the gear adjustment structure drives the first main body 512 and the second main body 513 to slide accordingly along the fixed part 511, thereby realizing the adjustment of the distance between the first main body 512 and the second main body 513.
[0145] Specifically, the gear adjustment structure in the present application includes a first bevel gear 5142, a second bevel gear 5143, a third bevel gear 5144, a first threaded rod 5145, a second threaded rod 5146, a first slider 5147 and a second slider 5148, wherein the first bevel gear 5142 is fixedly connected to the adjustment rod 5141, the second bevel gear 5143 and the third bevel gear 5144 are arranged opposite to each other, and the second bevel gear 5143 and the third bevel gear 5144 are both meshed with the first bevel gear 5142; the second bevel gear 5143 and the third bevel gear 5144 are meshed with the first bevel gear 5142; The bevel gear 5143 is fixedly connected to the first threaded rod 5145, and the third bevel gear 5144 is fixedly connected to the second threaded rod 5146; the first slider 5147 is threadedly connected to the first threaded rod 5145, and the first slider 5147 is fixedly connected to the first main body 512; the second slider 5148 is threadedly connected to the second threaded rod 5146, and the second slider 5148 is fixedly connected to the second main body 513; the number of the first slider 5147 and the second slider 5148 in this application are both two.
[0146] When it is necessary to adjust the spacing between the first main body portion 512 and the second main body portion 513, the adjusting rod 5141 is rotated. When the adjusting rod 5141 rotates, the first bevel gear 5142 is driven to rotate. Since the second bevel gear 5143 and the third bevel gear 5144 are both meshed with the first bevel gear 5142, and the second bevel gear 5143 and the third bevel gear 5144 are arranged opposite to each other, when the first bevel gear 5142 rotates, the second bevel gear 5143 and the third bevel gear 5144 are driven to rotate in opposite directions, and then the second bevel gear 5143 and the third bevel gear 5144 are further meshed with each other. The bevel gear 5144 drives the first threaded rod 5145 and the second threaded rod 5146 to rotate respectively, and the rotation directions of the first threaded rod 5145 and the second threaded rod 5146 are opposite; since the first slider 5147 is connected to the first threaded rod 5145 by a thread, and the position of the first threaded rod 5145 does not change during the rotation process, therefore, when the first threaded rod 5145 rotates, the first slider 5147 is driven to move along the axial direction of the first threaded rod 5145; and since the first slider 5147 is fixedly connected to the first main body 512, the first slider 5147 moves at the same time When the second slider 5148 is rotated, the first main body 512 is driven to move along the axial direction of the first threaded rod 5145; similarly, since the second slider 5148 is connected to the second threaded rod 5146 through a thread, and the position of the second threaded rod 5146 does not change during the rotation process, the second slider 5148 is driven to move along the axial direction of the second threaded rod 5146 when the second threaded rod 5146 rotates; and since the second slider 5148 is fixedly connected to the second main body 513, the second slider 5148 moves and drives the second main body 513 to move along the axial direction of the second threaded rod 5146. and because the first threaded rod 5145 and the second threaded rod 5146 rotate in opposite directions, the first slider 5147 and the second slider 5148 move in opposite directions, so that the first main body 512 and the second main body 513 move in opposite directions, that is, the first main body 512 and the second main body 513 always move toward the center of the book clamping device at the same time, or always move away from the center of the book clamping device at the same time, thereby increasing or decreasing the distance between the first main body 512 and the second main body 513, and then realizing operations such as clamping or taking out the spine of the book.
[0147] The maximum thickness of the book that can be clamped by the book clamping device is determined by the length of the first threaded rod 5145 and the second threaded rod 5146. The maximum thickness of the book that can be clamped in the present application is preferably 24 mm; this thickness range can meet the clamping requirements of most books on the market.
[0148] The number of the gear adjustment structures may be one or more. To improve the stability of the book clamping device structure, the present application preferably uses two gear adjustment structures. The two gear adjustment structures are respectively disposed at the two ends of the fixing portion 511 .
[0149] In order to facilitate the adjustment of the adjustment rod 5141, the gear adjustment structure in the present application further includes a first adjustment knob 5149, which is fixedly connected to the bottom end of the adjustment rod 5141. The bottom end of the adjustment rod 5141 in the present application specifically refers to the end of the adjustment rod 5141 close to the bottom of the book when the book clamping device is used. By providing the first adjustment knob 5149 fixedly connected to the adjustment rod 5141, the adjustment rod 5141 can be driven to rotate by rotating the first adjustment knob 5149, thereby reducing the difficulty of operation and facilitating use.
[0150] See also Figure 12 to Figure 15 As shown, the book pressing device 52 in the present application includes a pressure rod 521 for pressing and fixing the opened book pages, and a pressure rod adjustment structure 522 for adjusting the pressure rod 521; wherein, the pressure rod 521 is located in front of the book clamping device 51, and the pressure rod adjustment structure 522 is connected to the rear side of the book clamping device 51; the front of the book clamping device 51 in this article specifically refers to the side of the book clamping device 51 on which the book is placed; the pressure rod 521 is slidably connected to the pressure rod adjustment structure 522 along the front-to-back direction of the book clamping device 51, so that the position of the pressure rod 521 can be adjusted along the front-to-back direction of the book clamping device 51, thereby adjusting the distance between the pressure rod 521 and the book clamping device 51 through the pressure rod adjustment structure 522.
[0151] To facilitate clamping of books, the pressure rods 521 in the present application are distributed along the up and down directions of the book clamping device 51; specifically, the directions referred to by "up", "down", "front", "back", "left" and "right" in the present application refer to the directions indicated by the direction indicators in the accompanying drawings.
[0152] When using the book pressing device 52, firstly, the pressing rod 521 is adjusted in a direction away from the book clamping device 51 through the pressing rod adjusting structure 522, so that the distance between the pressing rod 521 and the book clamping device 51 is increased; the book is placed in front of the book clamping device 51, the pages are turned over, and the opened pages are placed between the pressing rod 521 and the book clamping device 51, and then the pressing rod 521 is adjusted in a direction close to the book clamping device 51 through the pressing rod adjusting structure 522, so that the distance between the pressing rod 521 and the book clamping device 51 is reduced, until the pressing rod 521 clamps the opened pages, thereby fixing the book.
[0153] To facilitate the adjustment of the position of the pressure rod 521, the pressure rod adjustment structure 522 in the present application includes a shell 5221 and a second adjustment structure arranged in the shell 5221; the upper and lower ends of the shell 5221 are provided with first slide grooves 5222 distributed along the front and rear directions of the book clamping device 51, and both ends of the pressure rod 521 are connected to the second adjustment structure through the first slide grooves 5222; a switch structure is also provided on the shell 5221, and the switch structure is connected to the second adjustment structure.
[0154] The operation of the second adjustment structure is controlled by a switch structure arranged on the shell 5221. During the operation of the second adjustment structure, the pressure rod 521 is driven to slide in the first slide groove 5222 on the shell 5221, so as to adjust the position of the pressure rod 521. The distance between the pressure rod 521 and the book clamping device 51 is adjusted by adjusting the position of the pressure rod 521.
[0155] The second adjustment structure in the present application includes a seventh connecting rod, an adjusting bolt 5223, a stepper motor 313 and a control module, wherein the seventh connecting rod is distributed in the up-down direction, and both ends of the seventh connecting rod are connected to the pressure rod 521 through the first slide groove 5222; specifically, the pressure rod 521 in the present application includes a pressure rod body 5211 distributed in the up-down direction, and two eighth connecting rods 5212 respectively connected to the two ends of the pressure rod body 5211, the eighth connecting rod 5212 is distributed in the front-to-back direction, and the eighth connecting rod 5212 is fixedly connected to the seventh connecting rod; the adjusting bolt 5223 is distributed in the front-to-back direction, the adjusting bolt 5223 and the stepper motor 313 are fixedly connected to the shell 5221, and the adjusting bolt 5223 is threadedly connected to the seventh connecting rod; the stepper motor 313 is connected to the adjusting bolt 5223; the switch structure and the stepper motor 313 are both connected to the control module signal.
[0156] The operation of the stepper motor 313 is controlled by a switch structure; during the operation of the stepper motor 313, the adjusting bolt 5223 is driven to rotate; specifically, in the present application, during the operation of the stepper motor 313, the synchronous wheel is driven to rotate by a synchronous belt, and the synchronous wheel is connected to the adjusting bolt 5223, so that the adjusting bolt 5223 is driven to rotate while the synchronous wheel rotates; since the adjusting bolt 5223 is fixedly connected to the housing 5221, and the adjusting bolt 5223 is connected to the seventh connecting rod by a thread, during the rotation of the adjusting bolt 5223, the seventh connecting rod is driven to move in the forward and backward direction along the adjusting bolt 5223; whether the movement of the seventh connecting rod is forward or backward is determined by the rotation direction of the stepper motor 313, and therefore, the seventh connecting rod can be controlled to move in the corresponding forward and backward direction by controlling the operation of the stepper motor 313.
[0157] When the seventh connecting rod moves forward or backward, it drives the eighth connecting rod 5212 connected thereto to move forward or backward, and then drives the pressure rod body 5211 to move forward or backward through the eighth connecting rod 5212; when the pressure rod body 5211 moves forward, the distance between the pressure rod 521 and the book clamping device 51 increases; when the pressure rod body 5211 moves backward, the distance between the pressure rod 521 and the book clamping device 51 decreases, thereby realizing the adjustment of the distance between the pressure rod 521 and the book clamping device 51.
[0158] In order to improve the degree of automation of the book pressing device 52, the seventh connecting rod in the present application includes a front connecting rod 5225 and a rear connecting rod 5226 arranged in parallel with each other, the front connecting rod 5225 is located on the side close to the book clamping device 51, and the rear connecting rod 5226 is located on the side away from the book clamping device 51; the front connecting rod 5225 and the rear connecting rod 5226 are connected by an axle pin, and the axle pin connection is provided with a gap; the axle pin connection in the present application specifically refers to that, of the front connecting rod 5225 and the rear connecting rod 5226, one connecting rod is provided with a connecting shaft, and the other connecting rod is provided with a connecting hole adapted to the connecting shaft; the connecting shaft is located in the connecting hole, and there is a certain gap between the connecting shaft and the connecting hole. , so that the front connecting rod 5225 is connected to the rear connecting rod 5226 through the connecting shaft and the connecting hole, and the connecting shaft can slide in the connecting hole within a certain range; the present application prefers that the gap is 2mm, that is, the distance between the front connecting rod 5225 and the rear connecting rod 5226 can float within a range of 2mm; both ends of the rear connecting rod 5226 are connected to the pressure rod 521; the adjusting bolt 5223 is connected to the front connecting rod 5225 by a thread; the front connecting rod 5225 is connected to a trigger plate 5227, and the rear connecting rod 5226 is provided with an infrared emitting device 5228 adapted to the trigger plate 5227, and the infrared emitting device 5228 is connected to the control module signal.
[0159] When it is necessary to turn the page, the stepping motor 313 is controlled by the switch structure to drive the adjusting bolt 5223 to rotate. When the adjusting bolt 5223 rotates, it drives the front connecting rod 5225 to move forward, that is, drives the front connecting rod 5225 to move in the direction close to the book clamping device 51; at the same time, since the front connecting rod 5225 is connected to the rear connecting rod 5226 by an axle pin, when the front connecting rod 5225 moves forward, it drives the rear connecting rod 5226 to move forward; and since the rear connecting rod 5226 is connected to the pressure rod 521, it drives the pressure rod 521 to move forward, so that the pressure rod 521 moves in the direction away from the book clamping device 51, and the distance between the pressure rod 521 and the book clamping device 51 increases, which is convenient for turning the pages of the book.
[0160] After turning the pages of the book, the stepper motor 313 is controlled to rotate in the reverse direction through the switch structure, so that the stepper motor 313 drives the adjusting bolt 5223 to rotate in the reverse direction. When the adjusting bolt 5223 rotates in the reverse direction, the front connecting rod 5225 is driven to move backward, that is, the front connecting rod 5225 is driven to move in the direction away from the book clamping device 51; at the same time, since the front connecting rod 5225 is connected to the rear connecting rod 5226 by the axle pin, when the front connecting rod 5225 moves backward, the rear connecting rod 5226 is driven to move backward; and since the rear connecting rod 5226 is connected to the pressure rod 521, the pressure rod 521 is driven to move backward, so that the pressure rod 521 moves in the direction close to the book clamping device 51; when the pressure rod 521 contacts the book, the book prevents the pressure rod 521 from continuing to move in the direction close to the book clamping device 51 At the same time, the rear connecting rod 5226 connected to the pressure rod 521 stops moving backward; at this time, the stepper motor 313 continues to rotate, driving the front connecting rod 5225 to continue to move in the direction away from the book clamping device 51, and at the same time, the front connecting rod 5225 drives the trigger plate 5227 to move in the direction away from the book clamping device 51; since the position of the rear connecting rod 5226 remains unchanged, the distance between the trigger plate 5227 and the infrared emitting device 5228 is reduced, and the trigger plate 5227 blocks the infrared rays emitted by the infrared emitting device 5228, triggering the stop operation command of the stepper motor 313, and the control module connected to the signal of the infrared emitting device 5228, such as a single chip microcomputer, issues a stop operation command for the stepper motor 313, and the stepper motor 313 stops running, thereby clamping the opened book pages.
[0161] Furthermore, in the present application, a buffer structure is provided between the front connecting rod 5225 and the rear connecting rod 5226, and the buffer structure preferably includes a spring. By providing the buffer structure, when the rear connecting rod 5226 stops running and the front connecting rod 5225 continues to move away from the book clamping device 51, the buffer structure applies resistance to the front connecting rod 5225 in the direction of approaching the book clamping device 51, thereby preventing the front connecting rod 5225 from applying too much force to the rear connecting rod 5226 during the movement, thereby preventing excessive pressure on the book, thereby improving safety.
[0162] In the present application, during the process of driving the pressure rod 521 to move forward and backward, the rotation direction of the output shaft of the stepper motor 313 is determined according to the extending direction of the thread of the adjusting bolt 5223 and other conditions, and is not specifically limited herein.
[0163] The switch structure in the present application can be a switch button, or a corresponding command button can be set in the form of a touch screen; for ease of use, the present application preferably has a switch structure including an infrared switch, which is used to sense the user's gestures, and the control module converts the gestures sensed by the infrared switch into electrical signals, and controls the operation of the stepper motor 313 through the electrical signals.

[0168] Specifically, the third adjustment structure 523 in the present application includes a first adjustment rod 5231, a gear structure fixedly connected to the first adjustment rod 5231, and a rack 5232 meshed with the gear structure; the rack 5232 is fixedly connected to the book clamping device 51 along the left-right direction. The first adjustment rod 5231 is distributed along the up-down direction; by rotating the first adjustment rod 5231, the gear structure is driven to rotate; because the gear structure is meshed with the rack 5232, and the rack 5232 is fixedly connected to the book clamping device 51, when the gear structure rotates, the pressure rod adjustment structure 522 is driven to move along the left-right direction, and the pressure rod 521 is driven to move along the left-right direction, thereby adjusting the position of the pressure rod 521 on the book clamping device 51 along the left-right direction, so that the pressure rod 521 can clamp books of different widths.
[0169] In order to improve the stability of the structure of the book pressing device 52, the present application preferably has two sets of gear structures, and the two sets of gear structures are respectively connected to the two ends of the first adjustment rod 5231. The present application preferably has a gear structure including a first gear 5233 and a second gear 5234 that mesh with each other, the first gear 5233 is fixedly connected to the first adjustment rod 5231, and the second gear 5234 is meshed with the first rack 5232, so that when the position of the pressing rod 521 in the left and right directions is adjusted, the moving direction of the pressing rod 521 is consistent with the rotation direction of the first adjustment rod 5231, so that the adjustment of the pressing rod 521 is more in line with the sensory perception of most users.
[0170] To facilitate the rotation of the first adjustment rod 5231 , the third adjustment structure 523 in the present application also includes a second adjustment knob 5235 , which is fixedly connected to the first adjustment rod 5231 , so that the first adjustment rod 5231 can be rotated by rotating the second adjustment knob 5235 .
[0171] In order to ensure the stability of the structure of the book pressing device 52, the third adjustment structure 523 in the present application also includes a guide rail 5236 and a second slide groove 5237 adapted to the guide rail 5236; the guide rail 5236 and the second slide groove 5237 are both distributed in the left-right direction; the second slide groove 5237 is fixedly connected to the housing 5221, and the guide rail 5236 is fixedly connected to the book clamping device 51. When the pressure rod adjustment structure 522 moves in the left-right direction, the guide rail 5236 slides in the second slide groove 5237, thereby improving the connection strength between the pressure rod adjustment structure 522 and the book clamping device 51, thereby improving the stability of the structure. Further, in the present application, a rubber or plastic structure is provided in the second slide groove 5237 to increase the damping between the guide rail 5236 and the second slide groove 5237, so that when the second adjustment knob 5235 stops rotating, the pressure rod adjustment structure 522 can stop moving immediately.
