[0030] Combined with Figures 2 to 8 , a writing board includes a support frame 1. A drawing mechanism 2 is arranged inside the support frame 1. A support mechanism 3 is fixedly connected to the bottom of the support frame 1. A writing panel 4 is fixedly connected to the inside of the front surface of the support frame 1;

[0031] The drawing mechanism 2 includes a slider 21. The slider 21 is slidably connected to the inside of the top end of the support frame 1. An L-shaped handle 22 is fixedly connected to the top of the slider 21. There are two L-shaped handles 22. Storage boxes 23 are respectively fixedly connected to the inner sides of the two L-shaped handles 22. An elastic band 24 is fixedly connected to the inside of the storage box 23. A positioning strip 25 is fixedly connected to the right end of the top of the support frame 1. A clamping seat 26 is fixedly connected to the front surface of the right L-shaped handle 22. A first spring 261 is fixedly connected to the front surface of the clamping seat 26. A T-shaped rod 27 is fixedly connected to the front surface of the first spring 261. A T-shaped round card shaft 28 is rotatably connected to the surface of the T-shaped rod 27. A gear rack 29 is rotatably connected to the top end of the back surface of the support frame 1. There are two gear racks 29. T-shaped support bars 291 are fixedly connected to the surfaces of the two gear racks 29. A hollow seat 292 is slidably connected to the surface of the T-shaped support bar 291. A T-shaped round shaft 293 is rotatably connected to the inside of the bottom end of the hollow seat 292. There are two T-shaped round shafts 293 and two storage boxes 23. One ends of the two T-shaped round shafts 293 are respectively rotatably connected to the back surfaces of the two storage boxes 23. A chute is opened in the inside of the top end of the support frame 1. The surface of the slider 21 is slidably connected to the inside of the chute.

[0032] Furthermore, positioning holes are formed on the surface of the positioning bar 25. One end of the surface of the T-shaped rod 27 matches the inside of the positioning hole. A circular groove is formed inside the card seat 26. The lower surface of the T-shaped circular card shaft 28 is movably connected to the inside of the circular groove. An E-shaped groove is formed at the top of the circular groove. The upper surface of the T-shaped circular card shaft 28 is located inside the E-shaped groove. Pull one of the L-shaped handles 22 to drive the movement of the T-shaped circular shaft 293 on its back, thereby driving the rotation of the hollow seat 292 and the T-shaped support bar 291, and simultaneously driving the rotation of the two T-shaped support bars 291 and the hollow seat 292 under the meshing action of the gear and the rack 29, and correspondingly driving the movement of the storage box 23 on the other side at the same time. Thus, the two storage boxes 23 can be pulled out of the support frame 1 simultaneously, facilitating the taking and using operations of writing tools. When it comes to storage after use, the writing tools can be stored under the action of the above structure, enabling the writing board to have a storage function and facilitating the use of the user.

[0033] Embodiment 2

[0034] Refer to Figures 1 - 8 and, on the basis of Embodiment 1, it is further obtained that the support mechanism 3 includes U-shaped seats 31. There are two U-shaped seats 31, and the two U-shaped seats 31 are respectively fixedly connected to the left and right sides of the support frame 1. A second spring 32 is fixedly connected inside the U-shaped seat 31. One end of the back of the second spring 32 is fixedly connected to a limit plate 33. A long rod 34 is fixedly connected inside the limit plate 33. One end of the long rod 34 is fixedly connected to a dial bar 35. A gantry frame 37 is fixedly connected to the bottom end of the back of the support frame 1. A rotating rod 38 is rotatably connected inside the gantry frame 37. A support base 39 is fixedly connected to the surface of the rotating rod 38. Positioning rings 36 are respectively fixedly connected to both ends of the rotating rod 38.

[0035] Furthermore, ring holes are formed on the surface of the positioning ring 36. The surface of the long rod 34 matches the inside of the ring holes. Through holes are formed inside the U-shaped seat 31. The surface of the long rod 34 penetrates through the through holes formed inside the U-shaped seat 31, enabling the support base 39 to rotate under the support of the rotating rod 38. After rotating to form a suitable angle with the support frame 1, the long rod 34 can be reinserted into the positioning ring 36. Thus, when in use, it is not necessary to hold the writing panel 4 by hand, and the writing panel 4 can form a certain angle, thereby facilitating the display of the writing panel 4.

[0036] During the actual operation process, when this device is in use and the writing tablet is being used, the writing tool is placed inside the storage box 23 and fixed by the elastic band 24. When it is necessary to use the writing tool for writing, first move the T-shaped round card shaft 28 to the right side of the E-shaped groove, and then pull the T-shaped rod 27 until one end of it disengages from the clamping position inside the positioning strip 25. Then, snap the T-shaped round card shaft 28 into the left side of the E-shaped groove. At this time, pull one of the L-shaped pull handles 22 to drive the T-shaped round shaft 293 on its back to move, thereby driving the hollow seat 292 and the T-shaped support bar 291 to rotate. Under the meshing action of the gear and rack 29, the two T-shaped support bars 291 and the hollow seat 292 rotate simultaneously, and correspondingly drive the storage box 23 on the other side to move at the same time. Thus, the two storage boxes 23 can be pulled out of the support frame 1 at the same time, facilitating the taking and using operations of the writing tool. When it comes to storage after use, the writing tool can be stored under the action of the above structure;

[0037] When writing, when it is necessary to support the writing panel 4 at a certain angle without holding it by hand, pull the bar 35 away from the support frame 1 at this time to drive the long rod 34 to move so that it disengages from inside the positioning ring 36. Then, the support base 39 can rotate under the support of the rotating rod 38. After rotating to form a suitable angle with the support frame 1, snap the long rod 34 back into the positioning ring 36. In this way, during use, there is no need to hold the writing panel 4 by hand, and the writing panel 4 can form a certain angle, thus facilitating the display of the writing panel 4.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or elements inherent to this process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
