In the present invention, the base plate 1 is rotatably connected to the base 2 through a rotating shaft, and the base plate 1 rotates up and down relative to the base 2. The structures of the two clamping arms 3 are the same. The clamping arms 3 are detachably and telescopically connected to the front end of the base 2. A hook 32 is provided at the front end of the clamping arm 3, and the hook 32 is used for clamping on the vehicle steering wheel. By moving the clamping arm 3 back and forth, the clamping space between the hook 32 and the base 2 is adjusted to form the installation and fixation of the base plate 1. Two mounting cavities 21 for mounting the clamping arms 3 are provided at the front end of the base 2. The mounting cavities 21 are rectangular cavities, polygonal cavities or cavities of any shape. The two mounting cavities 21 are located on the left and right sides of the front end of the base 2. An arc-shaped avoidance groove 24 with symmetrically opposite ends is provided between the two mounting cavities 21. An anti-slip rubber pad is provided in the arc-shaped avoidance groove 24. An avoidance hole 22 is provided through the mounting cavity 21 on the base 2. The avoidance hole 22 is located on the top wall of the mounting cavity 21. The avoidance hole 22 is a rectangular hole with a certain length and is arranged longitudinally to facilitate the front and back movement of the first button body 33. First teeth 23 are provided on the inner wall of the mounting cavity 21. The first teeth 23 and the avoidance hole 22 are located on the same wall surface of the mounting cavity 21. The clamping arm 3 includes a sliding seat 31. The hook 32 is rotatably connected to the sliding seat 31 with damping. The sliding seat 31 is adapted to the mounting cavity 21. The clamping arm 3 is an L-shaped structure as a whole. An arc-shaped groove body 321 is provided on the hook 32. The arc-shaped groove body 321 is an arc-shaped groove body with a spiral design to be adapted to the annular grip of the steering wheel. The arc-shaped groove body 321 is adapted to and closely fits the annular grip on the steering wheel. A flexible filler is fixedly provided in the arc-shaped groove body 321. The flexible filler is set to any one of flexible silicone, flexible plastic or cloth to prevent the hook 32 from scratching the leather wrapped on the outer surface of the vehicle steering wheel. The clamping arm 3 is slidably arranged in the mounting cavity 21 through the sliding seat 31. The sliding seat 31 includes a first button body 33 and a first return spring 34 arranged inside the housing of the sliding seat 31. The housing of the sliding seat 31 includes an upper housing 311 and a bottom housing 312. The bottom housing 312 is detachably connected to the upper housing 311 by screws or buckles for assembling the first button body 33 and the first return spring 34. The upper housing 311 and the bottom housing 312 have an accommodation cavity. The first button body 33 and the first return spring 34 are both installed in the accommodation cavity. Among them, the top end of the first return spring 34 contacts the bottom of the first button body 33, and the bottom end of the first return spring 34 abuts against the bottom of the accommodation cavity. The first button body 33 is connected to the sliding seat 31 for up and down pressing. The first return spring 34 is arranged below the first button body 33. The first return spring 34 is used for the pressing and resetting of the first button body 33. Second teeth 331 and protruding top posts 332 are provided on the upper surface of the first button body 33. The second teeth 331 and the protruding top posts 332 penetrate through the housing of the sliding seat 31. The second teeth 331 are engaged with the first teeth 23 on the mounting cavity 21. The top posts 332 pass through the avoidance hole 22 and extend out of the housing of the base 2. When the user needs to move the clamping arm 3 forward or backward, only need to press the top post 332 on the first button body 33. The first return spring 34 is compressed by the pressing force and deforms. At the same time, the first button body 33 slides downward. The second teeth 331 on the first button body 33 disengage from the first teeth 23 inside the mounting cavity 21. At this time, the clamping arm 3 is in an unlocked state. The clamping arm 3 can slide back and forth along the length direction of the mounting cavity 21, or the clamping arm 3 can be pulled out of the mounting cavity 21.The clamping arm 3 is disassembled to facilitate the overall storage. When the user releases the first button body 33, the first return spring 34 returns to its original position, and the first button body 33 slides upward to return to its initial state. The second teeth 331 on the first button body 33 engage with the first teeth 23 inside the installation cavity 21 to form a locked state of the clamping arm 3. The length of the avoidance hole 22 is the distance for the front-back movement of the clamping arm 3. For example, when the clamping arm 3 is moved backward, the hook 32 on the clamping arm 3 moves away from the base 2, and the clamping space between the hook 32 and the base 2 increases. When the clamping arm 3 is moved forward, the hook 32 on the clamping arm 3 approaches the base 2, and the clamping space between the hook 32 and the base 2 decreases; In this way, by providing two clamping arms 3 that can move back and forth, and allowing the user to adjust the clamping space between the base 2 and the hook 32 on the clamping arm 3 to fit the steering wheels of different vehicle models. Moreover, with the cooperation between the hook 32 and the base, the fixing effect is better, effectively enhancing the market applicability and usage scenarios of the product.

[0020] Embodiment 2 Such as Figure 6 And Figure 7As shown, the improvement of this embodiment is that the clamping arm 3 includes a rotating shaft 20, and the clamping hook 32 is fixedly connected to one end of the rotating shaft 20. The clamping arm is rotatably connected to the base 2 through the rotating shaft and the mounting cavity. The base 2 includes a second reset spring 35, a fixing nut 36 and an adjusting threaded rod 37. The second reset spring 35 and the fixing nut 36 are both located inside the shell of the base 2. The fixing nut 36 is fixedly installed behind the mounting cavity 21. Through holes are reserved on the rotating shaft 20 and the clamping hook 32. The adjusting threaded rod 37 passes through the through holes and the corresponding cavity wall of the mounting cavity 21 and is connected to the fixing nut 36. The front end of the adjusting threaded rod 37 is provided with an external thread tooth of a certain length, which is adapted to the internal thread tooth on the fixing nut 36. The adjusting threaded rod 37 is threadedly connected to the fixing nut 36, and the rear end of the adjusting threaded rod 37 is a twist handle The second return spring 35 is sleeved on the adjusting threaded rod 37, and the front end of the second return spring 35 abuts against the rotating shaft 20 on the card arm 3, and the rear end of the second return spring 35 abuts against the corresponding inner wall of the mounting cavity 21, forming an elastic support for the card arm 3 to slide forward and backward. In this embodiment, the mounting cavity 21 is a cylindrical cavity, and the rotating shaft 20 is adapted to the mounting cavity 21, and the rotating shaft 20 is inserted into the mounting cavity 21. When the user needs to move the substrate 1 forward and backward, the adjusting threaded rod 37 can be turned counterclockwise or clockwise. Under the thrust or pull of the adjusting threaded rod 37, the card arm 3 moves forward and backward along the length direction of the mounting cavity 21. For example, when the card arm 3 is moved backward, the hook 32 on the card arm 3 moves away from the base 2, and the clamping space between the hook 32 and the base 2 increases. When the card arm 3 is moved forward, the hook 32 on the card arm 3 is close to the base 2, The clamping space between the hook 32 and the base 2 is reduced. When the arm 3 moves to the innermost side of the base 2, the second return spring 35 is in a compressed state. When the adjusting threaded rod 37 is turned counterclockwise or clockwise, the arm 3 automatically moves forward under the return force of the second return spring 35. When the adjusting threaded rod 37 is completely disengaged from the fixing nut 36, the arm 3 can be disassembled, and adjustment, disassembly and installation are very convenient.

[0021] Embodiment 3 like Figures 8-11As shown in the figure, a support assembly 11 is provided on the substrate 1. One end of the support assembly 11 is connected to the base 2, and the other end of the support assembly 11 is connected to the substrate 1, forming a horizontal support effect on the substrate 1. The support assembly 11 includes a first connecting member 100, a second connecting member 101, and a third connecting member 102. One end of the first connecting member 100 is rotatably connected to the base 2, and the other end of the first connecting member 100 is rotatably connected to the second connecting member 101. One end of the third connecting member 102 is rotatably connected to the substrate 1, and the third connecting member 102 is slidably connected to the second connecting member 101 in the front and back directions. A locking mechanism is provided between the third connecting member 102 and the second connecting member 101. The locking mechanism is used to lock and unlock the position of the third connecting member 102 sliding in the front and back directions. The locking mechanism includes a second button body 30, a third return spring 40, and a third tooth pattern 50. The second button body 30 and the third return spring 40 are both provided inside the housing of the second connecting member 101. The housing of the second connecting member 101 includes a top shell 1011 and a bottom shell 1012. The top shell 1011 is detachably connected to the bottom shell 1012 by screws or snaps. There is a sliding cavity with a certain length inside the top shell 1011 and the bottom shell 1012. One end of the third connecting member 102 is inserted into the sliding cavity. The third return spring 40 is provided below the second button body 30. The third return spring 40 is used for the pressing and resetting of the second button body 30. The second button body 30 has the same structure as the first button body 33. The third tooth pattern 50 is located on the housing of the third connecting member 102. The third tooth pattern 50 is correspondingly arranged and meshed with the second tooth 331 on the second button body 30. In this embodiment, a relief groove 1021 with a certain depth and length is provided at the bottom of the third connecting member 102. A rectangular through hole 1022 is opened along the length direction in the middle of the relief groove 1021. The third tooth pattern 50 is evenly arranged on the two opposite sides of the rectangular through hole 1022. The second button body 30 is located in the relief groove 1021. The top post 332 on the second button body 30 passes through the rectangular through hole 1022 and extends out of the housing of the third connecting member 102 through the bottom shell 1012. When the second tooth 331 on the second button body 30 meshes with the third tooth pattern 50 on the third connecting member 102, it is the locked state of the third connecting member 102. When the user needs to adjust the pitch angle or horizontal state of the substrate 1, only need to press the second button body 30. When the second tooth 331 on the second button body 30 disengages from the third tooth pattern 50 on the third connecting member 102, at this time, it is the unlocked state of the third connecting member 102. At this time, the user moves the third connecting member 102 back and forth, so that the substrate 1 rotates up and down to adjust the horizontal state of the base 1; In this way, by setting the support assembly 11 in the present invention, the horizontal support of the substrate 1 by the support assembly 11 is utilized to increase the stability of the substrate. Moreover, the substrate 1 is rotatably connected to the base 2. Through the adjustment of the support assembly 11, the control of the pitch angle of the substrate 1 can be realized, thereby optimizing the user experience.

[0022] Working principle: The present invention includes a substrate 1, a base 2, and two clamping arms 3 arranged left and right on the base 2. When in use, first, unlock the clamping arm 3 by pressing the first button body 3 or loosen the adjusting threaded rod 37, and move the clamping arm 3 backward to a suitable position. At this time, the hook 32 on the clamping arm 3 is far away from the base 2, leaving enough installation space. Rotate the hook 32 on the clamping arm 3 so that the arc-shaped groove bodies 321 on the two hooks 32 are aligned with the back of the annular grip on the steering wheel one by one and snap in. The corresponding front of the annular grip on the steering wheel contacts the arc-shaped avoidance groove 24 on the base 2. Then, push the clamping arm 3 forward one by one or tighten the adjusting threaded rod 37. The clamping arm 3 moves towards the base 2, and the clamping space between the hook 32 and the base 2 shrinks until the hook 32 firmly clamps the annular grip of the steering wheel, forming a clamping state of the hook 32 and the base 2 on the vehicle steering wheel, completing the preliminary installation and fixation of the in-vehicle steering wheel table board. Then, by adjusting the third connecting member 102, the first connecting member 100 is brought into contact with the vehicle steering wheel, forming a supporting state for lifting the substrate 1. The user can adjust the front-back movement distance of the third connecting member 102, thereby adjusting the horizontal supporting state of the supporting component 11 for the substrate 1. The longitudinal accommodation space of the substrate 1 can also be increased by moving the clamping arm 3 back and forth, which can prevent the items placed on the substrate 1 from contacting the steering wheel.

[0023] In summary, the present invention is provided with two clamping arms 3 that can move back and forth, and allows the user to adjust the clamping space between the base 2 and the hook 32 to adapt to the steering wheels of different vehicle models. Moreover, by using the cooperation between the hook 32 and the base, the fixing effect is better, effectively enhancing the market applicability and usage scenarios of the product; The horizontal support of the substrate 1 by the support component 11 is used to increase the stability of the substrate. Moreover, the substrate 1 is rotatably connected to the base 2, and by adjusting the support component 11, the control of the pitching angle of the substrate 1 can be realized, thereby optimizing the user experience.
