Abstract

The application discloses a computer-aided input device for data processing, which comprises a frame plate, and first and second pull plates arranged on the two sides of the frame plate respectively. The elastic force of the second spring is utilized to pressurize the buffer sleeve, so that the clamping plate can be completely limited in the placing groove, and the slide rail and the clamping plate can clamp the side edges of the paper by the clamping groove. At this time, the side edges of the paper are placed on the bottom surface of the placing groove, so that the paper cannot fall from the surface of the frame plate, and the stability of the paper between the two clamping frames is improved. The half-ring frame with the same height as the limiting frame does not block the information data on the paper, and the positions of the two clamping frames relative to the two side edges of the paper, so that the user can directly see the data information on the paper. Due to the limitation of the auxiliary input device, the paper cannot shake and turn pages during the input process, and the user can quickly input the data information on the surface of the paper.

Description

Technical Field

[0001] This invention belongs to the field of information entry technology, and specifically relates to a computer-aided data entry device for data processing. Background Technology

[0002] A computer is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and has storage and memory functions. A computer is a modern intelligent electronic device that can run according to a program and automatically and rapidly process massive amounts of data. It consists of hardware and software systems.

[0003] With the development of computer technology, much information in documents needs to be entered into the network using computers, which necessitates the use of data entry aids. Existing computer-aided data entry devices mostly fix the paper to the top of the device, which is then placed on a desktop. During use, users need to frequently look up and down, which is tiring and reduces work efficiency over time. Even when paper documents are fixed to the device, existing fixing devices only restrict the top of the paper, making the document prone to shaking and page flipping. Users then need to re-fix the paper document, further reducing data entry efficiency.

[0004] Therefore, it is necessary to invent a computer-aided data entry device for data processing to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides a computer-aided data entry device for data processing, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a computer-aided data entry device for data processing, comprising a frame plate, a first pull plate and a second pull plate respectively provided on both sides of the frame plate, and two movable devices provided inside the frame plate, the outer ends of the two movable devices respectively penetrating the first through slots on both sides of the frame plate, and the first pull plate and the second pull plate respectively correspondingly connected to the two movable devices.

[0007] A semi-ring frame is provided on the front side of the frame plate, and a clamping device is provided on the inner side of the semi-ring frame. The inner side of the clamping device is fixedly connected to one end of the movable rod on the front side of the movable device, and the other end of the movable rod is connected to the movable device. A second through groove is provided on the front side of the frame plate, and the movable rod passes through the second through groove.

[0008] The bottom of the frame is provided with a base plate, which is connected to the frame by multiple screws. The bottom end of the screws penetrates the base plate, and the top end of the screws is threadedly connected to the frame.

[0009] Furthermore, the frame plate has two movable slots inside, and two movable devices correspond one-to-one with the two movable slots. The first through slot is connected to the second through slot through the movable slot. The movable device includes a sliding plate. The end of the movable rod is located inside the sliding groove of the sliding plate. The clamping device is slidably connected to the sliding groove of the sliding plate through the movable rod. The outer side of the sliding plate is provided with a ring plate. The first pull plate and the second pull plate are fixedly connected to the two sliding plates through the ring plate respectively.

[0010] Furthermore, the number of ring pieces is set to two, and a baffle is provided between the two ring pieces. The outer side of the baffle is corresponding to the inner side of the two ring pieces, and the outer side of the baffle is fixedly connected to the inner side wall of the movable groove through a limiting rod. A limiting groove corresponding to the limiting rod is provided at the center of each of the two ring pieces, and the ring pieces are slidably connected to the limiting rod through the limiting groove.

[0011] Furthermore, the overall shape of both ring pieces is set as a quarter-ring-shaped structure. The two ring pieces are symmetrically arranged with the horizontal center line of the baffle as the axis, and the concave surfaces of the two ring pieces are arranged opposite each other. The ring pieces pass through the first through groove, and the convex surfaces of the two ring pieces slide corresponding to the side wall of the first through groove.

[0012] Furthermore, both of the outer sides of the baffles are provided with adjusting screws, the inner ends of the adjusting screws are in contact with the outer sides of the baffles, the outer ends of the adjusting screws pass through the first through groove, and the two adjusting screws pass through the center of the first pull plate and the second pull plate respectively. The center of the outer side of the first pull plate and the second pull plate are rotatably connected with rotating sleeves, and the rotating sleeves are spirally sleeved on the outer end surface of the adjusting screws.

[0013] Both of the baffles are provided with a first spring on their inner sides. One end of the first spring is in contact with the inner side of the baffle, and the other end of the first spring is in contact with the outer side of the slide plate. The first spring is located between the two ring plates.

[0014] Furthermore, the clamping device includes two clamps, each clamp including a slide, with a placement groove provided on the inner side of the slide, and a clamping plate provided inside the placement groove. One end of the movable rod passes through the clamping plate, and the end passing through the clamping plate is fixedly connected to the side wall surface of the placement groove. A buffer sleeve is also provided inside the placement groove, and the buffer sleeve is fitted onto the surface of the movable rod and is made of silicone material.

[0015] Furthermore, the clamping plate slides in correspondence with the placement groove via a movable rod. The length of the placement groove is the same as the length of the clamping plate, and the bottom surface of the placement groove corresponds to and fits against the bottom surface of the clamping plate.

[0016] The shape of the placement groove is the same as that of the clamping plate, and the clamping plate forms a clamping groove with the placement groove through the buffer sleeve.

[0017] Furthermore, both clamps are attached to the front side of the frame plate via clamping plates, and the placement slots of the two slides are arranged opposite each other. A limiting frame is provided on the outer side of the clamp, a slide bar is provided on the inner side of the limiting frame, and a groove is provided on the outer side of the slide. Both slides are slidably connected to the slide bar through the groove.

[0018] Furthermore, the clamping device also includes a bracket, with both ends of the bracket passing through a semi-ring frame and both ends of the bracket being fixedly connected to the outer side of the limiting frame. The height of the semi-ring frame is the same as the height of the limiting frame, and the semi-ring frame and the limiting frame are on the same horizontal plane. Both ends of the bracket are provided with a second spring, one end of the second spring being in contact with the inner side of the semi-ring frame, and the other end of the second spring being in contact with the outer side of the limiting frame.

[0019] Furthermore, the end cross-sectional shape of the slide bar is set to be oval, and the width of the oval slide bar end is greater than the width of the inner side of the slide bar. The length of the slide bar is less than the length of the limiting frame, and the slide bar and the limiting frame are integrated.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. This invention utilizes the elastic force of the second spring to pressurize the buffer sleeve by the slide and clamp, allowing the clamp to be completely confined within the placement slot. This facilitates the slide and clamp to hold the sides of the paper using the slot, with the bottom of the paper's sides resting on the bottom surface of the placement slot. This prevents the paper from falling off the shelf surface and improves the stability of the paper between the two clamps. The semi-circular frame, at the same height as the limiting frame, does not obstruct the information data on the paper. At the same time, the relative positions of the two clamps holding the sides of the paper allow the user to directly see the data information on the paper. Due to the limitations of the auxiliary input device, the paper will not shake or flip during the input process, allowing the user to quickly input the data information on the paper surface.

[0022] 2. This invention allows for the individual movement of the first or second pull plate, or simultaneous movement of both. Utilizing a rotating sleeve in conjunction with an adjusting screw, and constrained by a first spring, the first and / or second pull plates can drive the clamps to slide on the surface of the slide bar via a ring, a sliding plate, and a movable rod. This allows the distance between the two clamps to vary between a maximum and a minimum distance, facilitating the clamping of different sizes of paper in the auxiliary input device and improving its adaptability to various paper sizes.

[0023] 3. This invention allows the user to directly pull the first and / or second pull plates. The first and / or second pull plates, through the ring plates, cause the sliding plate to compress the first spring. At the same time, the sliding plate can drive the clamps to move on the slide bar through the movable rod until the two sides of the plate are respectively in the clamping grooves of the two clamps. When the first and / or second pull plates are released, the elastic force of the first spring rebounds. The elastic force of the two first springs is used to make the two clamps clamp the plate with high hardness, which improves the stability of the plate between the two clamps and makes it convenient for the user to enter the data information of the plate surface.

[0024] 4. This invention connects multiple screws to the bottom surface of the mounting plate with threads at one end, and then the bottom end of the screws penetrates through the base plate, with the bottom end face of the screws flush with the bottom surface of the base plate. By using the base plate and screws in cooperation, the entire auxiliary input device can be stably placed on the computer desktop. The screws of appropriate length also make the front side of the mounting plate flush with the user's face, allowing the user to quickly observe the data information on the paper on the front side of the mounting plate in the horizontal direction without having to frequently look down or up, thus reducing the burden on the user's neck.

[0025] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides a computer-aided data entry device for data processing, such as... Figure 1 As shown, the device includes a frame plate 1, with a first pull plate 2 and a second pull plate 3 respectively on both sides of the frame plate 1. Two movable devices are installed inside the frame plate 1, with their outer ends penetrating through first through slots 4 on both sides of the frame plate 1. The first pull plate 2 and the second pull plate 3 are connected to the two movable devices one-to-one. A semi-ring frame 5 is installed on the front side of the frame plate 1, with a clamping device on its inner side. The inner side of the clamping device is fixedly connected to one end of a movable rod 6 on the front side of the movable device, and the other end of the movable rod 6 is connected to the movable device. A second through slot 7 is provided on the front side of the frame plate 1, through which the movable rod 6 passes. A base plate 8 is installed at the bottom of the frame plate 1, connected to the frame plate 1 by multiple screws 9, with the bottom end of the screws 9 penetrating the base plate 8 and the top end of the screws 9 threadedly connected to the frame plate 1. After connecting one end of multiple screws 9 to the bottom surface of the frame plate 1 with threads, the bottom end of the installed screws 9 passes through the base plate 8, and the bottom end face of the screws 9 is flush with the bottom surface of the base plate 8. With the cooperation of the base plate 8 and the screws 9, the entire auxiliary input device can be stably placed on the computer desktop. The screws 9 of appropriate length make the front side of the frame plate 1 flush with the user's face, so that the user can quickly observe the data information on the paper on the front side of the frame plate 1 in the horizontal direction without having to frequently look down or up, thus reducing the burden on the user's neck.

[0035] exist Figure 1In this design, the shelf 1 has two movable slots 10 inside, and two movable devices correspond one-to-one with the two movable slots 10. A first through slot 4 communicates with a second through slot 7 via the movable slots 10. Each movable device includes a sliding plate 11, with the end of a movable rod 6 located inside a groove 12 of the sliding plate 11. A clamping device is slidably connected to the groove 12 of the sliding plate 11 via the movable rod 6. An annular piece 13 is provided on the outer side of the sliding plate 11. A first pull plate 2 and a second pull plate 3 are both fixedly connected to the two sliding plates 11 via the annular piece 13. When the sliding plate 11 slides inside the movable slots 10, it can drive the clamping bracket 20 to slide on the surface of the slide bar 26 via the movable rod 6. The movable slots 10 limit the maximum and minimum distance between the two clamping brackets 20, thereby allowing real-time adjustment of the distance between the two clamping brackets 20 according to the size of the paper.

[0036] exist Figure 1 and Figure 3 In this design, two annular pieces 13 are provided, with a baffle 14 positioned between them. The outer side of the baffle 14 corresponds to the inner side of the two annular pieces 13, and the outer side of the baffle 14 is fixedly connected to the inner wall of the movable groove 10 via a limiting rod 15. Each of the two annular pieces 13 has a limiting groove 16 at its center, corresponding to the limiting rod 15, and the annular pieces 13 are slidably connected to the limiting rod 15 via the limiting groove 16. The overall shape of both annular pieces 13 is a quarter-ring-shaped structure. The two annular pieces 13 are symmetrically arranged about the horizontal center line of the baffle 14, and their concave surfaces face each other. The annular pieces 13 penetrate the first through groove 4, and their convex surfaces slidably correspond to the side wall of the first through groove 4. When the first pull plate 2 and / or the second pull plate 3 drive the slide plate 11 to move inside the movable groove 10 via the ring plate 13, the concave surface of the ring plate 13 slides on the outer side surface of the baffle 14. Since the convex surfaces of the two ring plates 13 correspond to the side sliding of the first through groove 4, the first pull plate 2 and / or the second pull plate 3 and the slide plate 11 can move stably, preventing the first pull plate 2 and / or the second pull plate 3 from shaking during movement. The baffle 14 uses the limiting rod 15 to limit the limiting groove 16 of the ring plate 13, so that the first pull plate 2 and / or the second pull plate 3 can only move in the horizontal direction. When the rotating sleeve 18 rotates, the limiting rod 15 can limit the ring plate 13, thereby preventing the first pull plate 2 and / or the second pull plate 3 and the slide plate 11 from rotating.

[0037] exist Figure 1 and Figure 2In this configuration, each of the two baffles 14 has an adjusting screw 17 on its outer side. The inner end of the adjusting screw 17 is in contact with the outer side of the baffle 14. The outer end of the adjusting screw 17 passes through the first through groove 4. The two adjusting screws 17 pass through the center of the first pull plate 2 and the second pull plate 3, respectively. A rotating sleeve 18 is rotatably connected to the center of the outer side of the first pull plate 2 and the second pull plate 3. The rotating sleeve 18 is spirally sleeved on the outer end surface of the adjusting screw 17. Each of the two baffles 14 has a first spring 19 on its inner side. One end of the first spring 19 is in contact with the inner side of the baffle 14, and the other end of the first spring 19 is in contact with the outer side of the slide plate 11. The first spring 19 is located between the two ring plates 13. When it is necessary to change the distance between the two clamps 20, the first pull plate 2 or the second pull plate 3 can be moved individually, or the first pull plate 2 and the second pull plate 3 can be moved simultaneously. The rotating sleeve 18 can be used in conjunction with the adjusting screw 17. Under the constraint of the first spring 19, the first pull plate 2 and / or the second pull plate 3 can drive the clamp 20 to slide on the surface of the slide bar 26 through the ring plate 13, the slide plate 11 and the movable rod 6. The distance between the two clamps 20 can be adjusted appropriately according to the shape of the paper. When clamping a plate with high hardness, the distance between the two clamps 20 can be adjusted, and the first pull plate 2 and / or the second pull plate 3 can be pulled directly. The first pull plate 2 and / or the second pull plate 3, through the ring plate 13, cause the slide plate 11 to squeeze the first spring 19. At the same time, the slide plate 11 can drive the clamp 20 to move on the slide bar 26 through the movable rod 6 until the two sides of the plate are respectively in the clamping grooves of the two clamps 20. When the first pull plate 2 and / or the second pull plate 3 are released, the elastic force of the first spring 19 rebounds. The elastic force of the two first springs 19 is used to make the two clamps 20 clamp the plate, which improves the stability of the plate between the two clamps 20.

[0038] exist Figure 1 and Figure 4 The clamping device includes two clamps 20. When neither of the outer surfaces of the two sliding plates 11 can press against the first spring 19, the two clamps 20 are at their maximum distance. When both inner surfaces of the two sliding plates 11 are in contact with the inner surface of the movable groove 10, the two clamps 20 are at their minimum distance. Each clamp 20 includes a slide 21 with a placement groove 22 inside. A clamping plate 23 is located inside the placement groove 22. One end of the movable rod 6 passes through the clamping plate 23 and is fixedly connected to the side wall surface of the placement groove 22. A buffer sleeve 24 is also provided inside the placement groove 22, fitted onto the surface of the movable rod 6, and made of silicone material. The device allows for the individual movement of one clamp 20 or simultaneous movement of both clamps 20, enabling the distance between the two clamps 20 to vary between maximum and minimum distances. This facilitates the clamping of different sized papers by the auxiliary input device, improving its adaptability to various paper sizes.

[0039] exist Figure 1 and Figure 4 In this configuration, the clamping plate 23 slides in correspondence with the placement groove 22 via the movable rod 6. The length of the placement groove 22 is the same as the length of the clamping plate 23, and the bottom surface of the placement groove 22 corresponds to and fits against the bottom surface of the clamping plate 23. The shape of the placement groove 22 is equal to the shape of the clamping plate 23, and the clamping plate 23 forms a clamping groove with the placement groove 22 through the buffer sleeve 24. The elastic force of the second spring 28 causes the slide 21 and the clamping plate 23 to press against the buffer sleeve 24, so that the clamping plate 23 can be completely confined inside the placement groove 22. This allows the slide 21 and the clamping plate 23 to clamp the side of the paper using the clamping groove. At this time, the bottom side of the paper rests on the bottom surface of the placement groove 22, which can prevent the paper from falling off the surface of the frame plate 1 and improve the stability of the paper between the two clamps 20.

[0040] exist Figure 1 and Figure 5 In this configuration, both clamps 20 are attached to the front side of the frame plate 1 via clamping plates 23, and the placement slots 22 of the two slides 21 are arranged opposite each other. A limiting frame 25 is provided on the outer side of each clamp 20, and a slide bar 26 is provided on the inner side of the limiting frame 25. A groove is provided on the outer side of each slide 21, and both slides 21 are slidably connected to the slide bar 26 via the groove. The end cross-section of the slide bar 26 is oval, with the width of the oval end being greater than the width of the inner side of the slide bar 26. The length of the slide bar 26 is less than the length of the limiting frame 25, and the slide bar 26 and the limiting frame 25 are integrated. The oval outer end of the slide bar 26 improves the connection stability between the slides 21 and the slide bar 26, facilitating stable left and right sliding of the slides 21 on the surface of the slide bar 26 via the groove, and preventing the slides 21 from detaching from the slide bar 26. When the support 27 is moved, the support 27 can drive the slide 21 to move back and forth through the slider 26 on the limiting frame 25, so that the slide 21 and the clamping plate 23 can hold the paper.

[0041] exist Figure 1 The clamping device further includes a bracket 27, with both ends of the bracket 27 penetrating the semi-ring frame 5 and fixedly connected to the outer side of the limiting frame 25. The height of the semi-ring frame 5 is the same as the height of the limiting frame 25, and the semi-ring frame 5 and the limiting frame 25 are on the same horizontal plane. A second spring 28 is provided on both ends of the bracket 27, with one end of the second spring 28 fitting against the inner side of the semi-ring frame 5 and the other end fitting against the outer side of the limiting frame 25. The semi-ring frame 5, at the same height as the limiting frame 25, does not obstruct the information data on the paper. Simultaneously, the relative positions of the two clamps 20 clamping the sides of the paper allow the user to directly see the data information on the paper. Due to the limitations of the auxiliary input device, the paper will not shake or flip during input, facilitating quick data entry by the user.

[0042] Working principle of this invention:

[0043] Refer to the instruction manual appendix Figure 1-5 Before inputting the data from the paper into the computer, the height of the entire auxiliary input device needs to be adjusted. Select a suitable length of screw 9, connect one end of multiple screws 9 to the bottom surface of the holder plate 1, and then insert the bottom end of the installed screw 9 through the base plate 8, with the bottom end face of the screw 9 flush with the bottom surface of the base plate 8. With the cooperation of the base plate 8 and the screw 9, the entire auxiliary input device can be stably placed on the computer desktop. The appropriate length of screw 9 also makes the front side of the holder plate 1 flush with the user's face, allowing the user to quickly observe the data on the paper on the front side of the holder plate 1 in the horizontal direction without having to frequently look down or up, thus reducing the burden on the user's neck.

[0044] After the height of the entire auxiliary input device is adjusted, before the data information on the paper is entered into the computer, the paper needs to be confined to the front side of the shelf 1.

[0045] When holding paper, the distance between the two clamps 20 can be adjusted according to the shape of the paper. At this time, the inner sides of the first pull plate 2 and the second pull plate 3 are respectively in contact with the two sides of the frame plate 1.

[0046] The distance between the two clamps 20 needs to be increased. The elastic force of the first spring 19 is used to make the inner end of the adjusting screw 17 fit against the outer side of the baffle 14. If the first pull plate 2 is moved and the rotating sleeve 18 on the first pull plate 2 is rotated, due to the limitation of the adjusting screw 17 by the baffle 14, the spiral effect of the rotating sleeve 18 and the adjusting screw 17 causes the first pull plate 2 to move on the surface of the adjusting screw 17 on the left. At this time, the first pull plate 2 pulls the left slide plate 11 to the left inside the movable groove 10 on the left through the ring plate 13 on the left. The left slide plate 11 and the left baffle 14 cooperate to press the first spring 19 on the left. The left slide plate 11 drives the left clamp 20 to move to the left on the slide bar 26 through the movable rod 6, thereby increasing the distance between the two clamps 20.

[0047] If the second pull plate 3 is moved, the rotating sleeve 18 on the second pull plate 3 is rotated. The spiral effect of the rotating sleeve 18 and the adjusting screw 17 causes the second pull plate 3 to move on the surface of the adjusting screw 17 on the right side. At this time, the first pull plate 2 pulls the right slide plate 11 to the right inside the right movable groove 10 through the right ring plate 13. The right slide plate 11 and the right baffle 14 cooperate to press the right first spring 19. The right slide plate 11 drives the right clamp 20 to move to the right on the slide bar 26 through the movable rod 6, which facilitates increasing the distance between the two clamps 20.

[0048] The first pull plate 2 and the second pull plate 3 can also be moved simultaneously, rotating the two rotating sleeves 18, causing the two clamps 20 to slide on the slide bar 26, increasing the distance between the two clamps 20. When it is necessary to reduce the distance between the two clamps 20, the rotating sleeve 18 is rotated in the opposite direction, and the elastic force of the first spring 19 rebounds. Utilizing the helical engagement between the rotating sleeve 18 and the adjusting screw 17, as well as the rebound force of the first spring 19, the slide plate 11 located at the outer end of the movable groove 10 gradually moves towards the inner end of the movable groove 10, thereby reducing the distance between the two clamps 20. The distance between the two clamps 20 can be adjusted according to the size of the paper. It is possible to move one clamp 20 individually or both clamps 20 simultaneously, allowing the distance between the two clamps 20 to vary between the maximum and minimum distances. This facilitates the clamping of different sizes of paper by the entire auxiliary input device, improving its adaptability to different paper sizes.

[0049] After the distance between the two clamps 20 is defined, when paper needs to be clamped, the support 27 is pulled. The support 27 compresses the second spring 28 through the limiting frame 25. At this time, the limiting frame 25 gradually moves away from the frame plate 1. The elastic force of the buffer sleeve 24 rebounds, causing the clamp 23 to slide on the surface of the movable rod 6. A clamping groove is formed between the clamp 23 and the placement groove 22. The outer side of the clamp 23 is always in contact with the front side of the frame plate 1. At the same time, the slide 21 also drives the end of the movable rod 6 to move inside the slide groove 12, clamping the two sides of the paper respectively. Placed inside the corresponding slots of the two clamps 20, the support 27 is released, and the elastic force of the second spring 28 rebounds, causing the limiting frame 25 to move towards the frame plate 1. The buffer sleeve 24 reduces the impact force between the slide 21 and the clamp plate 23. Since the frame plate 1 limits the clamp plate 23, the slide 21 and the clamp plate 23 clamp the side of the paper. At this time, the bottom side of the paper is placed on the bottom surface of the placement slot 22, which can prevent the paper from falling off the surface of the frame plate 1 and improve the stability of the paper between the two clamps 20.

[0050] When the paper needs to be replaced, simply pull the bracket 27. At this time, the elasticity of the buffer sleeve 24 causes the clamp 23 to separate from the slide 21, making it easy to pull the paper directly out between the two clamps 20. Place the new paper inside the clamping slots of the two clamps 20, release the bracket 27, and use the elasticity of the second spring 28 to clamp the paper again.

[0051] When clamping a plate with high hardness, the distance between the two clamps 20 can be adjusted, and the first pull plate 2 and / or the second pull plate 3 can be pulled directly. The first pull plate 2 and / or the second pull plate 3, through the ring plate 13, cause the slide plate 11 to squeeze the first spring 19. At the same time, the slide plate 11 can drive the clamp 20 to move on the slide bar 26 through the movable rod 6 until the two sides of the plate are respectively in the clamping grooves of the two clamps 20. When the first pull plate 2 and / or the second pull plate 3 are released, the elastic force of the first spring 19 rebounds. The elastic force of the two first springs 19 is used to make the two clamps 20 clamp the plate, which improves the stability of the plate between the two clamps 20.

[0052] Since the limiting frame 25 and the semi-ring frame 5 are on the same horizontal plane and have the same height, the semi-ring frame 5 will not block the information data on the paper. At the same time, the two clamps 20 hold the two sides of the paper respectively, so that the user can directly see the data information on the paper. Due to the limitation of the auxiliary input device, the paper will not shake or turn during the input process, which makes it convenient for the user to quickly input the data information on the paper surface.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
