An imaging scanning driving device and a driving method

Abstract

The present invention discloses an imaging scanning driving device and a driving method, which include a supporting mechanism. The supporting mechanism includes a base as a substrate. On the upper end surface of the base, sliding platforms are symmetrically fixedly connected with the center as the axis. On the opposite sides of the two sliding platforms, a placement plate for placing the palm is slidably connected. In the present invention, the displacement mechanism drives the upper moving frame and the lower moving frame to move synchronously. During the moving process, the guiding mechanism drives the placement plate to move. The upper moving frame, the lower moving frame, and the placement plate will move towards each other synchronously, which can accelerate the scanning progress. At the same time, finger gap airbags are also arranged on the placement plate. During the movement of the upper moving frame, the compression mechanism will work to supply air to the finger gap airbags. After the finger gap airbags expand, they will produce a squeezing and supporting effect on the fingers. At this time, the fingers will automatically unfold, and the scanning heads on the upper moving frame and the lower moving frame will also obtain clearer scanning images of the palm during the scanning process.

[0002] As an important branch of modern science and technology, imaging scanning technology plays a vital role in many fields, including medical diagnosis. In the medical field, imaging scanning technology is widely used to visualize the internal structure of the human body, helping doctors to accurately judge the condition and formulate treatment plans. Traditional methods mostly use X-rays, CT, MRI and other methods to achieve imaging scanning.

[0003] In the existing technology, scanning equipment can usually only realize a single scanning platform movement, which not only limits the scanning speed, but also may cause instability and errors in the scanning process. When the palm is in a disabled state, the patient cannot independently control the extension of the fingers. The existing scanning equipment often ignores the situation of the fingers being together, and there is no effective mechanism to ensure that the fingers are spread and flat during the scanning process, which affects the clarity and accuracy of the scanning image, and then affects the subsequent recognition and analysis process.

[0015] A driving method for an imaging scanning driving device

[0016] S1. Place the palm on the upper end face of the placement board, insert the middle finger and ring finger into the gap formed by the finger gap airbag, then the driving mechanism starts to work and drives the displacement mechanism to move. The upper moving frame and the lower moving frame will move synchronously, and the upper and lower areas of the palm will be scanned by the scanning head;

[0017] S2. During the movement of the upper moving frame, the guiding rope will be pulled. At this time, the placement board will move linearly through the guiding rope under the movement of the upper moving frame. The moving direction of the upper moving frame is opposite to that of the placement board, and it can cooperate with the scanning head during the scanning process to accelerate the scanning progress;

[0018] S3. After the driving mechanism starts to work, one output end of the driving motor drives the second driving rod to rotate, thereby driving the cam to rotate and cooperate with the compression mechanism, so that the compression mechanism can generate gas, and the gas is transported to the finger gap airbag through the expansion mechanism. After the finger gap airbag is filled with gas, it will expand and squeeze the fingers, causing them to expand outwards, which can be more accurate during the scanning process by the scanning head and avoid the situation where the scanning accuracy decreases due to the fingers being closed together.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In the present invention, a displacement mechanism is provided to synchronously move the upper moving frame and the lower moving frame. During the movement, the placement board will be driven to move through the guiding mechanism. The upper moving frame, the lower moving frame and the placement board will move synchronously in opposite directions. During this process, the scanning progress can be accelerated. At the same time, a finger gap airbag is also provided on the placement board. During the movement of the upper moving frame, the compression mechanism will work to supply gas to the finger gap airbag. After the finger gap airbag expands, it will have an effect of squeezing and supporting the fingers. At this time, the fingers will automatically expand, and the scanning imaging of the palm by the scanning heads on the upper and lower moving frames will also be clearer during the scanning process.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 - Figure 4 The present invention provides a technical solution: an imaging scanning driving device, including a support mechanism 1. The support mechanism 1 includes a base 11 as a base. Symmetrically fixed to the upper end face of the base 11 are sliding platforms 12. A placement plate 13 for placing the palm is slidably connected to one side of the two sliding platforms 12 facing each other. Fixed to the outer side wall of the base 11 is a support frame 14. Fixed to the upper end face of the support frame 14 is a protective frame 15. Symmetrically fixed to the upper end face of the base 11 below the sliding platforms 12 are U-shaped frames 16. A displacement mechanism 2 is provided on one side of the two U-shaped frames 16 facing each other. Above the two U-shaped frames 16 is a guiding mechanism 3 for driving the synchronous movement of the placement plate 13 and a partial structure of the displacement mechanism 2. Inside the protective frame 15 is a driving mechanism 4 for driving the displacement mechanism 2 to work. Inside the placement plate 13 is an expansion mechanism 6 for expanding the fingers. On one side of the driving mechanism 4 inside the protective frame 15 is a compression mechanism 5 for providing a power source for the expansion mechanism 6.

[0037] With the above technical solution, the sliding connection between the symmetrically arranged sliding platforms 12 and the placement plate 13 enables different-sized palms to be properly placed, realizing personalized adjustment. The design of the sliding platforms 12 also facilitates the rapid positioning and fixing of the palm position, improving the scanning efficiency. The ingenious setting of the displacement mechanism 2 enables the scanning head 19 to accurately move along a predetermined trajectory, covering the entire palm area and achieving a comprehensive and detailed scan. The introduction of the guiding mechanism 3 realizes the synchronous movement of the placement plate 13 and a partial structure of the displacement mechanism 2. This innovative design not only enhances the stability during the scanning process but also enables the scanning head 19 to always maintain the best distance from the palm, thereby improving the quality of the scanned image. By precisely controlling the working state of the driving mechanism 4, flexible adjustment of the scanning speed and accuracy can be achieved to meet the requirements of different application scenarios. The expansion mechanism 6 can moderately expand the fingers, effectively solving the problem of scanning blind spots caused by the fingers being closely attached, making the scanning results more complete and accurate.

[0038] Please refer to Figure 2 - Figure 5, on the opposite sides of the two U-shaped frames 16, sliding grooves 17 are provided. Inside the two U-shaped frames 16, tooth grooves 18 are evenly provided. Symmetrically and fixedly connected to the lower end surface of the placing plate 13 are first fixing brackets 131. Symmetrically and fixedly connected to the lower end surface of the sliding table 12 are second fixing brackets 132. At the interval between the first fixing brackets 131 and the second fixing brackets 132, a damping reset device 133 for facilitating the reset of the placing plate 13 is fixedly connected by bolts.

[0039] With the above technical solution, the design of the sliding grooves 17 provided on the opposite sides of the two U-shaped frames 16 provides a stable and smooth sliding path for the placing plate 13 and its connecting components, ensuring that the fine adjustment of the palm position during the scanning process can be carried out accurately and smoothly. At the same time, the tooth grooves 18 evenly provided inside the U-shaped frames 16 provide precise meshing points for subsequent meshing, ensuring that the displacement mechanism 2 can drive the placing plate 13 and the palm thereon to perform the scanning movement accurately. The introduction of the damping reset device 133 can automatically help the placing plate 13 reset to the initial position after the scanning is completed, thereby simplifying the operation process and improving the work efficiency. At the same time, the buffering effect of the damping reset device 133 can also effectively reduce the impact and noise generated by the rapid reset, enhancing the user experience.

[0040] Please refer to Figure 4 - Figure 7 , the displacement mechanism 2 includes an upper moving frame 21 and a lower moving frame 22 which are mirror-symmetrically arranged. On the opposite sides of the upper moving frame 21 and the lower moving frame 22, a plurality of scanning heads 19 for scanning the human palm are fixedly connected. On the outer side walls of the upper moving frame 21 and the lower moving frame 22, hanging plates 24 are fixedly connected. On the sides of the plurality of hanging plates 24 away from the upper moving frame 21 and the lower moving frame 22, movable wheels 26 are rotatably sleeved, and the movable wheels 26 are slidably connected inside the sliding grooves 17. On the outer side walls of the upper moving frame 21 and the lower moving frame 22, fixed rods 23 are rotatably sleeved. At the ends of the two fixed rods 23, gears 25 meshing and driving with the tooth grooves 18 are fixedly connected. On the outer wall of the fixed rod 23 connected to the upper moving frame 21, a first synchronous wheel 231 is fixedly sleeved. On the outer wall of the fixed rod 23 connected to the lower moving frame 22, a first clamping frame 221 is fixedly sleeved.

[0041] With the above technical solution, several scanning heads 19 are evenly distributed on the opposite side of the upper moving frame 21 and the lower moving frame 22, which can scan every part of the palm in great detail, ensuring a clear understanding of the bones of the palm after scanning. The smooth sliding of the movable wheel 26 inside the chute 17 ensures that the upper moving frame 21 and the lower moving frame 22 can move smoothly along the predetermined trajectory, thus realizing the full coverage of the palm by the scanning head 19. The gear 25 at the end of the fixed rod 23 is in meshing transmission with the tooth groove 18 inside the U-shaped frame 16, realizing the precise positioning and motion control of the displacement mechanism 2. The first synchronous wheel 231 fixedly sleeved on the outer wall of the fixed rod 23 connected to the upper moving frame 21 and the first clamping frame 221 fixedly sleeved on the outer wall of the fixed rod 23 connected to the lower moving frame 22 provide important structural support for the synchronous motion and fixed connection of the displacement mechanism 2.

[0042] Please refer to Figure 4 - Figure 10 On the outer walls of the two fixed rods 23, on one side of the first clamping frame 221 and the first synchronous wheel 231, there is a V-shaped limiting plate 27 rotatably connected through a bearing, and the V-shaped limiting plate 27 is rotatably connected to the first clamping frame 221 and the first synchronous wheel 231. On the side of the V-shaped limiting plate 27 away from the protective frame 15, there is a synchronous plate 28 fixedly connected, and both ends of the synchronous plate 28 are fixedly connected with limiting push frames 281. The limiting push frame 281 on the side close to the lower moving frame 22 is rotatably sleeved on the outer wall of the first clamping frame 221.

[0043] With the above technical solution, the rotational connection between the V-shaped limiting plate 27 and the first clamping frame 221 and the first synchronous wheel 231 further improves the flexibility of the structure, enabling the V-shaped limiting plate 27 to play a supporting role while limiting the lower moving frame 22 to ensure the synchronous motion of the upper moving frame 21 and the lower moving frame 22. The limiting push frames 281 fixedly connected to both ends of the synchronous plate 28 not only enhance the structural strength of the synchronous plate 28 but also provide a reliable support point for its connection with components such as the first clamping frame 221. Especially, the limiting push frame 281 on the side close to the lower moving frame 22 is rotatably sleeved on the outer wall of the first clamping frame 221. This design not only ensures the synchronous motion between the synchronous plate 28 and the lower moving frame 22 but also realizes the further limiting and stabilization of the first clamping frame 221 through the rotational connection of the limiting push frame 281.

[0044] Please refer to Figure 4 - Figure 7, the guiding mechanism 3 includes a mounting plate 31 fixedly connected to the upper end faces of two U-shaped frames 16. On the opposite sides of the two mounting plates 31, guiding wheels 32 are symmetrically and rotatably sleeved. At the edge of the upper end face of the upward moving frame 21 and at the center of the placing plate 13 close to one side of the protective frame 15, limit blocks 33 are fixedly connected. A guiding rope 34 is arranged between the two limit blocks 33. The guiding rope 34 is wound around the outer walls of the two guiding wheels 32, and the guiding wheels 32 are slidably connected to the two guiding ropes 34.

[0045] With the above technical solution, through the mounting plate 31 fixedly connected to the upper end faces of the two U-shaped frames 16, the guiding mechanism 3 is stably installed at the key position of the scanning system. The mounting plate 31 not only provides reliable support for components such as the guiding wheels 32, but also ensures the structural stability and durability of the entire guiding mechanism 3. The two guiding wheels 32 are symmetrically and rotatably sleeved on the opposite sides of the mounting plate 31. Their existence provides the necessary guiding and support for the smooth sliding of the guiding rope 34. By connecting the two limit blocks 33 with the guiding rope 34 and winding it around the outer walls of the two guiding wheels 32, precise control and guidance of the movement trajectory of the displacement mechanism 2 are achieved.

[0046] Please refer to Figure 11 and Figure 12 , the driving mechanism 4 includes a load-bearing plate 41 slidably connected to the inner bottom end of the protective frame 15. A driving motor 42 is fixedly connected to the upper end face of the load-bearing plate 41. One output end of the driving motor 42 is fixedly connected to a first driving rod 43, and the first driving rod 43 penetrates through the protective frame 15 and is slidably connected to the protective frame 15. A second synchronous wheel 44 is fixedly connected to the outer wall of the first driving rod 43. A second clamping frame 222 is fixedly connected to the end of the first driving rod 43. The end of the V-shaped limiting plate 27 away from the upward moving frame 21 is rotatably connected to the first driving rod 43 through a bearing, and the V-shaped limiting plate 27 is located on both sides of the second clamping frame 222 and the second synchronous wheel 44. A synchronous belt 45 is sleeved on the outer walls of the first synchronous wheel 231 and the second synchronous wheel 44. Second electric push rods 46 are symmetrically and fixedly connected to the inner side wall of the protective frame 15. The telescopic ends of the second electric push rods 46 are fixedly connected to the outer side wall of the load-bearing plate 41. The output end of the driving motor 42 away from the first driving rod 43 is fixedly connected to a second driving rod 47, and a cam 48 is fixedly connected to the end of the second driving rod 47.

[0047] With the above technical solution, the drive motor 42 serves as the power source of the drive mechanism 4, and its performance directly affects the movement speed and accuracy of the scanning head 19. The first drive rod 43 penetrates through the protective frame 15 and is slidably connected to the protective frame 15. The second synchronous pulley 44 fixed to its outer wall is connected to the first synchronous pulley 231 through a synchronous belt 45, realizing the synchronous movement between the displacement mechanism 2 and the drive motor 42. This not only simplifies the structure of the drive mechanism 4 but also improves the transmission accuracy and reliability. At the same time, the end of the first drive rod 43 is fixedly connected to the second bracket 222, and the rotational connection with the V-shaped limit plate 27 further enhances the structural stability and movement stability. The introduction of the second electric push rod 46 provides additional power support for the drive mechanism 4. Its telescopic end is fixedly connected to the outer wall of the load-bearing plate 41. By adjusting the telescopic length of the second electric push rod 46, the linear position adjustment of the load-bearing plate 41 and the entire drive mechanism 4 can be achieved, so as to meet the position adjustment under different scanning requirements.

[0048] Please refer to Figure 11 and Figure 12 , the compression mechanism 5 includes guide frames 51 symmetrically and fixedly connected to the upper end surface of the load-bearing plate 41. A piston rod 52 is slidably sleeved inside the guide frame 51. Rotating sleeves 54 are provided at the ends of the two piston rods 52 close to the cam 48. A positioning plate 53 is fixedly connected to the outer wall of the piston rod 52. A limit spring 56 that ensures the roller 54 abuts against the end surface of the cam 48 is fixedly connected to the side of the positioning plate 53 close to the guide frame 51. One end of the piston rod 52 away from the cam 48 is fixedly connected to a piston head body 55. Piston cylinders 57 are symmetrically and fixedly connected to the upper end surface of the load-bearing plate 41 on one side of the guide frame 51, and the piston head body 55 is slidably sleeved inside the piston cylinder 57. Intake valves 58 are provided at the intake ends of the two piston cylinders 57.

[0049] With the above technical solution, the guide frame 51, as the basic structure of the compression mechanism 5, is symmetrically and fixedly connected to the upper end surface of the load-bearing plate 41, providing stable guidance for the sliding of the piston rod 52. The piston rod 52 is slidably sleeved inside the guide frame 51, and a roller 54 is rotatably sleeved at one end of the piston rod 52 close to the cam 48. The roller 54 not only reduces the frictional resistance between the cam 48, but also improves the smoothness and durability of the movement. When the cam 48 rotates, the change in its contour will push the roller 54 and the piston rod 52 to reciprocate along the guide frame 51. The existence of the limit spring 56 ensures that the roller 54 always abuts against the end surface of the cam 48. Even when the contour of the cam 48 changes greatly, stable contact and transmission can be maintained, which not only improves the accuracy and reliability of the transmission, but also provides the necessary restoring force for the reciprocating movement of the piston rod 52. When the piston rod 52 reciprocates, the piston head body 55 will slide inside the piston cylinder 57, thereby changing the volume and pressure of the gas in the cylinder. The intake ends of the two piston cylinders 57 are provided with intake valves 58. This design allows external gas to enter the piston cylinder 57 when needed, providing the necessary initial conditions for gas compression. At the same time, the opening and closing of the intake valve 58 can be precisely controlled according to actual needs, so as to realize flexible adjustment of gas charging.

[0050] Please refer to Figure 11 - Figure 13 As shown in, the expansion mechanism 6 includes an intelligent control air plate 61 fixedly connected inside the placement plate 13. A plurality of first air pipes 62 are fixedly connected to the air outlet end of the intelligent control air plate 61. A plurality of finger joint air bags 64 are fixedly connected to the upper end surface of the placement plate 13. The end of the first air pipe 62 is fixedly connected to the air inlet end of the finger joint air bag 64. A constant pressure valve 63 for stabilizing the gas pressure is arranged inside the intelligent control air plate 61. The air inlet end of the intelligent control air plate 61 is fixedly connected to a second air pipe 65 that can penetrate the protective frame 15. The air outlet ends of the two piston cylinders 57 are fixedly connected to a three-way pipe 67. The end of the three-way pipe 67 is fixedly connected to a corrugated air pipe 66 that can be telescoped. The end of the corrugated air pipe 66 is fixedly connected to the second air pipe 65. The exhaust end of the intelligent control air plate 61 is fixedly connected to an exhaust pipe 68 that penetrates the placement plate 13. An exhaust valve 69 is installed on the outer wall of the exhaust pipe 68 at the edge of the placement plate 13.

[0051] With the above technical solution, the intelligent control air plate 61, as the core component of the expansion mechanism 6, integrates advanced control technology and a constant pressure valve 63 inside. It can achieve precise control and stable output of gas pressure. By being fixedly connected inside the placement plate 13, the intelligent control air plate 61 can be conveniently connected to components such as the first air pipe 62, providing a stable and reliable gas supply for actuators such as the finger gap airbag 64. Through the precise control of the intelligent control air plate 61, the finger gap airbag 64 can simulate the opening and closing actions of fingers, achieving tight fitting and effective fixation of the object to be scanned. This not only improves the accuracy and stability of scanning but also provides a more comfortable and natural scanning experience for users. The introduction of the three-way pipe 67 and the corrugated air pipe 66 provides a more flexible and convenient path for the transmission of gas from the piston cylinder 57 to the intelligent control air plate 61. The telescopic design of the corrugated air pipe 66 enables it to adapt to gas transmission requirements at different positions and angles, thereby improving the adaptability and flexibility of the entire expansion mechanism 6. By precisely controlling the opening and closing of the exhaust valve 69, precise control of the gas discharge speed and discharge volume can be achieved, thus ensuring the stability and controllability of the gas pressure inside the intelligent control air plate 61.

[0052] Please refer to Figure 9 and Figure 10 As shown in, a first electric push rod 29 is fixedly connected to the outer side wall of the protective frame 15. The telescopic end of the first electric push rod 29 is fixedly connected to a mounting frame 291, and the mounting frame 291 is slidably connected to the outer side wall of the protective frame 15. The outer side wall of the mounting frame 291 is fixedly connected to the outer side wall of the V-shaped limiting plate 27.

[0053] With the above technical solution, the telescopic end of the first electric push rod 29 is ingeniously fixedly connected to the mounting frame 291. The adoption of this connection method enables the mounting frame 291 to move flexibly with the telescopic movement of the first electric push rod 29, greatly increasing the flexibility and adaptability of the operation. Through the close combination with the mounting frame 291, precise positioning and effective restraint of the object to be limited can be achieved, thereby greatly enhancing the safety and reliability of the entire displacement mechanism 2.

[0054] A driving method for an imaging scanning driving device, please refer to Figure 1 - Figure 13 ,

[0055] S1. Place the palm on the upper end surface of the placement plate 13, and insert the middle finger and the ring finger into the gap formed by the finger gap airbag 64. Then, the driving mechanism 4 starts to work and drives the displacement mechanism 2 to move. The upper moving frame 21 and the lower moving frame 22 will move synchronously, and the upper and lower regions of the palm will be scanned by the scanning head 19.

[0056] S2. During the movement of the upper moving frame 21, the guide rope 34 will be pulled. At this time, the placement plate 13 will realize linear motion through the guide rope 34 under the movement of the upper moving frame 21. The movement direction of the upper moving frame 21 is opposite to that of the placement plate 13. During the scanning process of the scanning head 19, the upper moving frame 21 can cooperate with the placement plate 13 to speed up the scanning progress.

[0057] S3. After the driving mechanism 4 starts working, an output end of the driving motor 42 drives the second driving rod 47 to rotate, and then drives the cam 48 to rotate, and cooperates with the compression mechanism 5, so that the compression mechanism 5 can generate gas, and the gas is transported to the finger gap airbag 64 through the expansion mechanism 6. The finger gap airbag 64 will expand after being filled with gas, and squeeze the finger to expand it to the surroundings, which can make the scanning process of the scanning head 19 more accurate and avoid the situation where the scanning accuracy is reduced due to the fingers being close together.

[0058] For scanning of human palms: when scanning the palms, it is necessary to first place the palms on the upper end surface of the placement plate 13, and insert the middle finger and the ring finger into the gaps formed by several finger gap airbags 64, and then start the drive motor 42 to drive the first drive rod 43 to rotate. After the first drive rod 43 rotates, it will drive the second synchronous wheel 44 and the synchronous belt 45 to rotate, and the synchronous belt 45 is sleeved on the outer walls of the second synchronous wheel 44 and the first synchronous wheel 231, so that the first synchronous wheel 231 and the fixed rod 23 can be driven to rotate. Since gears 25 are respectively provided at both ends of the fixed rod 23, the gear 25 meshes with the tooth grooves 18 opened inside the U-shaped frame 16. At this time, the rotation of the gear 25 can move back and forth inside the U-shaped frame 16, and push the upper moving frame 21 to move. By providing a V-shaped limit plate 27, it can The lower moving frame 22 is driven to move synchronously. During the movement of the upper moving frame 21, the first clamping frame 221 will be pushed to move through the V-shaped limit plate 27, the synchronous plate 28 and the limit push frame 281, so as to achieve the purpose of driving the lower moving frame 22 synchronously. Since the upper moving frame 21 and the lower moving frame 22 are synchronously moved through the V-shaped limit plate 27, when the V-shaped limit plate 27 moves, the telescopic end of the first electric push rod 29 will push the mounting frame 291 to move, thereby driving the V-shaped limit plate 27 to move, and the telescopic end of the second electric push rod 46 will also push the load-bearing plate 41, thereby cooperating with the V-shaped limit plate 27 to realize the movement of the upper moving frame 21 and the lower moving frame 22, and the upper moving frame 21 and the lower moving frame 22 are provided with a scanning head 19 at the opposite end, through which the palm can be scanned and transmitted to an external imaging device;

[0059] Supplementary description of the guiding mechanism 3 and the expansion mechanism 6: During the movement of the upper moving frame 21, the guiding rope 34 will be pulled. The guiding rope 34 is wound around the outer walls of two guiding wheels 32, and the other end is connected to the end of the placement plate 13. Therefore, when the upper moving frame 21 pulls the guiding rope 34 to move, the guiding wheels 32 will rotate to reduce the friction, and the placement plate 13 will be pulled. The placement plate 13 slides on the outer wall of the sliding table 12. At this time, the upper moving frame 21 and the lower moving frame 22 move away from the protective frame 15, while the placement plate 13 moves towards the protective frame 15. In this way, the scanning time can be reduced and synchronous scanning can be carried out. After the driving motor 42 works, it can synchronously drive the second driving rod 47 to rotate. The driving motor 42 is a double-shaft motor. When the second driving rod 47 drives the cam 48 to rotate, it will cooperate with the two piston rods 52. The end face of the cam 48 forms a sliding connection with the roller 54 at the end of the piston rod 52. When the convex surface of the end face of the cam 48 contacts the piston rod 52, the piston rod 52 moves and squeezes the limit spring 56. The end of the piston rod 52 is provided with a piston head body 55, and the piston head body 55 is located inside the piston cylinder 57. At this time, the piston head body 55 reciprocates, and the air flow inside the piston cylinder 57 is accelerated. The gas is sent into the second air pipe 65 and the intelligent control air plate 61 through the three-way pipe 67 and the corrugated air pipe 66. The intelligent control air plate 61 will send the gas into the finger joint airbag 64 through the first air pipe 62. At this time, the finger joint airbag 64 will expand and squeeze and support the fingers. At this time, the fingers will move around when being squeezed, and the fingers will tend to be straight after being supported and be at the same height as the back of the hand, and there will be no situation where the finger area is low. When scanning the palm, it will be more accurate. At the same time, through the reciprocating movement of the two piston rods 52 and the piston head body 55, the gas movement speed can be accelerated. And a constant pressure valve 63 is also provided inside the intelligent control air plate 61 to ensure the stability of the gas inside the finger joint airbag 64 and avoid excessive gas. Excessive gas will control the exhaust valve 69 to open through the intelligent control air plate 61. At this time, the gas inside the intelligent control air plate 61 and the finger joint airbag 64 will be discharged through the exhaust pipe 68, so as to achieve the purpose of stabilizing the gas.
