Description

[0002] In the field of video monitoring, film shooting, production and manufacturing, the equipment or material is supported by a platform, and the angle of the equipment or workpiece is often adjusted by the angle of the platform. Spatial adjustment generally involves six degrees of freedom (three distance degrees of freedom and three angle degrees of freedom). The conventional adjustment mode of the angle degree of freedom generally uses a pair of main materials for one degree of freedom. In specific practice, the angle of the upper material is deflected relative to the rotation center of the lower material by a gear / cam / screw or a screw thread, thereby achieving the purpose of adjusting the angle.
[0003] When adjusting two or more angle degrees of freedom, the adjustment is realized by the superposition of two adjustment modules (meaning that two degrees of freedom require two pairs of main materials). However, this angle adjustment mode uses a large number of materials, increases the volume and complexity of the platform, and the error affecting the angle accuracy is also accumulated and expanded.

[0050] Embodiment one
[0051] In combination Figures 1 to 2 The application provides an angle adjusting platform 10. The angle adjusting platform 10 comprises a base 100, an adjusting platform 200, a first adjusting rod 310, a second adjusting rod 320 and a first elastic member 330. The adjusting platform 200 is rotatably mounted on the base 100 in a first direction 101. Specifically, the base 100 has a first direction 101, a second direction 102 and a third direction 103 perpendicular to each other. Alternatively, the base 100 is plate-shaped, and the first direction 101 is the thickness direction of the base 100.
[0052] The length direction of the first adjusting rod 310 is consistent with the first direction 101, one end of the first adjusting rod 310 abuts against one of the base 100 and the adjusting platform 200, and the other end of the first adjusting rod 310 is adjustably connected to the other of the base 100 and the adjusting platform 200.
[0053] In some embodiments, in combination Figures 1 to 3One end of the first adjusting rod 310 abuts against the adjusting table 200, limiting the first adjusting rod 310 from continuously moving towards the base 100 along the first direction 101 relative to the adjusting table 200, and the other end of the first adjusting rod 310 is adjustably connected to the base 100. By adjusting the position, the adjusting table 200 can be pulled towards the base 100 along the first direction 101, so as to adjust the included angle between the base 100 and the adjusting table 200.
[0054] For example, the adjusting table 200 has a first through hole 201 extending along the first direction 101, the base 100 has a first threaded hole 106 extending along the first direction 101, and one end of the first adjusting rod 310 abuts against the side of the adjusting table 200 away from the base 100, i.e., the head of the first adjusting rod 310 cannot pass through the first through hole 201. The other end of the first adjusting rod 310 passes through the first through hole 201 and is threadedly connected to the first threaded hole 106. By threadedly connecting, the position of the other end of the first adjusting rod 310 in the base 100 can be accurately adjusted, so that the included angle between the adjusting table 200 and the base 100 can be finely adjusted, thereby meeting the demand for high-precision angle adjustment. At the same time, by adjusting the tightness of the threaded connection, the inaccuracy caused by manufacturing errors or wear can also be compensated to a certain extent. Compared with simple sliding or hinging, the threaded connection not only converts the helical motion of the thread into the motion of the adjusting table 200 in the direction of the screw axis, but also correspondingly generates the angle change with respect to the rotation center, and enhances the stability of the connection, so as to resist greater external forces and vibrations, ensure that the adjusting table 200 maintains a stable posture during adjustment, and has a simple setting manner and is conducive to reducing manufacturing costs. The user can easily adjust the position of the first adjusting rod 310 by rotating it, without the need for complex tools or operations, thereby reducing the use difficulty and improving the adjustment efficiency. In the present scheme, the first adjusting rod 310 can be compactly installed in the base 100 by using the first through hole 201 on the adjusting table 200 and the first threaded hole 106 on the base 100, without occupying too much space, which helps to reduce the overall volume of the angle adjustment platform 10 and improve the space utilization.
[0055] For another example, the adjusting table 200 has a first through hole 201 extending along the first direction 101, the base 100 has a first clamping hole extending along the first direction 101, and one end of the first adjusting rod 310 abuts against the side of the adjusting table 200 away from the base 100, i.e., the head of the first adjusting rod 310 cannot pass through the first through hole 201. The other end of the first adjusting rod 310 passes through the first through hole 201 and is adjustably clamped in the first clamping hole.
[0056] It can be understood that the first adjusting rod 310 is adjustably mounted on the base 100, and in addition to threaded connection, clamping, sliding connection, adjustably bonded position, adjustably magnetic position, etc. can be used, which are not specifically limited here.
[0057] In some embodiments, the first adjusting rod 310 is adjustably mounted on the base 100, and in addition to threaded connection, clamping, sliding connection, adjustably bonded position, adjustably magnetic position, etc. can be used, which are not specifically limited here.
[0058] In some embodiments, the first adjusting rod 310 is adjustably mounted on the base 100, and in addition to threaded connection, clamping, sliding connection, adjustably bonded position, adjustably magnetic position, etc. can be used, which are not specifically limited here.
[0059] In some embodiments, the first adjusting rod 310 is adjustably mounted on the base 100, and in addition to threaded connection, clamping, sliding connection, adjustably bonded position, adjustably magnetic position, etc. can be used, which are not specifically limited here. Figures 1 to 3
[0060] For example, in combination with Figures 1 to 3 The adjusting table 200 has a second through hole 202 extending along the first direction 101, the base 100 has a second threaded hole 107 extending along the first direction 101, one end of the second adjusting rod 320 abuts against the side of the adjusting table 200 away from the base 100, and the other end of the second adjusting rod 320 passes through the second through hole 202 and is threadedly connected to the second threaded hole 107. Through the threaded connection, the position of the other end of the second adjusting rod 320 in the base 100 can be accurately adjusted, so that the included angle between the adjusting table 200 and the base 100 can be finely adjusted to meet the needs of high-precision angle adjustment. At the same time, by adjusting the tightness of the threaded connection, the inaccuracy caused by manufacturing errors or wear can also be compensated to a certain extent. Compared with simple sliding or hinging, the threaded connection not only converts the helical motion of the thread into the motion of the adjusting table 200 in the direction of the screw axis, but also enhances the stability of the connection, can resist greater external forces and vibrations, ensures that the adjusting table 200 maintains a stable posture during adjustment, and the setting method is simple, which is conducive to reducing manufacturing costs. Users can easily adjust the position of the second adjusting rod 320 by rotating it without the need for complex tools or operations, reducing the difficulty of use and improving the adjustment efficiency. In this scheme, the second adjusting rod 320 can be compactly installed in the base 100 by using the second through hole 202 on the adjusting table 200 and the second threaded hole 107 on the base 100, without occupying too much space, which helps to reduce the overall volume of the angle adjusting platform 10 and improve the space utilization.
[0061] For another example, the adjusting table 200 has a second through hole 202 extending along the first direction 101, the base 100 has a second clamping hole extending along the first direction 101, one end of the second adjusting rod 320 abuts against the side of the adjusting table 200 away from the base 100, i.e. the head of the second adjusting rod 320 cannot pass through the second through hole 202. The other end of the second adjusting rod 320 passes through the second through hole 202 and is adjustably clamped in the second clamping hole.
[0062] It can be understood that the second adjusting rod 320 is adjustably installed on the base 100, and in addition to threaded connection, clamping, it can also be connected by sliding, adjustably bonded, adjustably magnetized, etc., which is not limited here.
[0063] In some other embodiments, one end of the second adjusting rod 320 abuts against the base 100, limiting the second adjusting rod 320 from moving continuously towards the adjusting table 200 along the first direction 101 relative to the base 100, and the other end of the second adjusting rod 320 is adjustably connected to the adjusting table 200. By adjusting the position, the base 100 can be pulled towards the adjusting table 200 along the first direction 101, and the angle between the base 100 and the adjusting table 200 can be adjusted. For example, the base 100 has a through hole extending along the first direction 101, and the adjusting table 200 has a threaded hole extending along the first direction 101. One end of the second adjusting rod 320 abuts against the side of the base 100 away from the adjusting table 200, i.e., the head of the second adjusting rod 320 cannot pass through the through hole. The other end of the second adjusting rod 320 passes through the through hole and is threadedly connected to the threaded hole. By threadedly connecting, the position of the other end of the second adjusting rod 320 in the adjusting table 200 can be accurately adjusted, so that the angle between the adjusting table 200 and the base 100 can be finely adjusted, thereby meeting the requirement of high-precision angle adjustment. For another example, the base 100 has a through hole extending along the first direction 101, and the adjusting table 200 has a clamping hole extending along the first direction 101. One end of the second adjusting rod 320 abuts against the side of the base 100 away from the adjusting table 200, i.e., the head of the second adjusting rod 320 cannot pass through the through hole. The other end of the second adjusting rod 320 passes through the through hole and is adjustably clamped in the clamping hole. It can be understood that the second adjusting rod 320 is adjustably mounted on the adjusting table 200, and in addition to threadedly connecting and clamping, it can also be slidably connected, adjustably bonded, adjustably magnetically attracted, etc., which are not limited here.
[0064] In the present embodiment, the first elastic member 330 is compressed between the base 100 and the adjusting table 200 along the first direction 101. The first elastic member 330 limits the base 100 and the adjusting table 200 from approaching each other without external force, provides stable support force for the adjusting table 200, prevents the adjusting table 200 from shaking or deviating during angle adjustment, and thus enhances the stability of the entire angle-adjusting platform 10. In combination with the abutting effect of the first adjusting rod 310 and the second adjusting rod 320, the base 100 and the adjusting table 200 are limited from moving away from each other without external force, thereby ensuring that the base 100 and the adjusting table 200 are relatively stationary without external force. The number of the first elastic member 330 can be one, two or more, which is not limited here. The first elastic member 330 can be sleeved with the first adjusting rod 310, can be sleeved with the second adjusting rod 320, or can be clamped between the base 100 and the adjusting table 200 without sleeving the first adjusting rod 310 and the second adjusting rod 320, which is not limited here.
[0065] In some embodiments, the number of the first elastic members 330 is more than two, and part of the first elastic members 330 are sleeved with the first adjusting rod 310, and the first adjusting rod 310 provides circumferential limiting for the first elastic members 330, so as to ensure the position stability of the first elastic members 330 in the plane perpendicular to the first direction 101. Meanwhile, the first elastic members 330 can provide additional damping effect when the position of the first adjusting rod 310 is adjusted, further reducing vibration and impact, ensuring the stability of adjustment, and the elastic deformation can absorb part of the energy generated in the adjustment process, so that the angle adjustment is more smooth and smooth, and the first adjusting rod 310 can better maintain its position when subjected to external force, avoiding the angle deviation caused by external force interference. Further, for higher intensity vibration, the first elastic members 330, the first adjusting rod 310 and the elastic body 350 are combined to realize vibration absorption.
[0066] In some embodiments, the number of the first elastic members 330 is more than two, and part of the first elastic members 330 are sleeved with the second adjusting rod 320, and the second adjusting rod 320 provides circumferential limiting for the first elastic members 330, so as to ensure the position stability of the first elastic members 330 in the plane perpendicular to the first direction 101. Meanwhile, the first elastic members 330 can provide additional damping effect when the position of the second adjusting rod 320 is adjusted, further reducing vibration and impact, ensuring the stability of adjustment, and the elastic deformation can absorb part of the energy generated in the adjustment process, so that the angle adjustment is more smooth and smooth, and the second adjusting rod 320 can better maintain its position when subjected to external force, avoiding the angle deviation caused by external force interference.
[0067] In some other embodiments, the first adjusting rod 310 is sleeved with the first elastic member 330, and the second adjusting rod 320 is sleeved with the first elastic member 330. For example, in combination with Figure 1 and Figure 2 , the number of the first adjusting rod 310 is one, the number of the second adjusting rod 320 is one, and the number of the first elastic member 330 is two, one of the first elastic members 330 is sleeved with the first adjusting rod 310, and the other first elastic member 330 is sleeved with the second adjusting rod 320.
[0068] In this embodiment, by adjusting the connection length of the first adjusting rod 310 and the second adjusting rod 320, the first adjusting rod 310 can be adjusted first and then the second adjusting rod 320 is adjusted, for example, the distance between the base 100 and the adjusting table 200 at the first adjusting rod 310 and the second adjusting rod 320 is increased, and the distance corresponds to the same central angle, so as to realize the rotation of the adjusting table 200 relative to the base 100 around the line (see the second direction 102) connecting the first adjusting rod 310 and the second adjusting rod 320, and realize one angle degree adjustment. By adjusting the connection length of the first adjusting rod 310 or the second adjusting rod 320 alone, for example, the distance between the base 100 and the adjusting table 200 at the first adjusting rod 310 or the second adjusting rod 320 is increased, so as to realize the rotation of the adjusting table 200 relative to the base 100 around the perpendicular line (see the third direction 103) of the line connecting the first adjusting rod 310 and the second adjusting rod 320, and realize another angle degree adjustment. Based on this, the first adjusting rod 310 and the second adjusting rod 320 can be linked to realize the adjustment of two angle degrees, without the need to use multiple pairs of main materials for superposition, which not only greatly simplifies the structure of the angle adjusting table 10, but also significantly reduces the required material quantity, reduces the volume and improves the integration, reduces the manufacturing cost, complexity and cumulative error, and improves the angle adjusting precision.
[0069] In this embodiment, the video monitoring camera, the camera, the lens or the workpiece to be processed and the like work components can be installed on the adjusting table 200, and by adjusting the angle degree of freedom between the adjusting table 200 and the base 100, the angle adjustment of the work component is realized, and the camera angle, the photographing angle or the processing angle is adjusted. In this embodiment, the angles of two work components can also be adjusted, for example, one work component is installed on the adjusting table 200, and the other work component is installed on the base 100, and by adjusting the angle degree of freedom between the adjusting table 200 and the base 100, the angle degree of freedom between the two work components is realized.
[0070] In some embodiments, in combination with Figure 3 and Figure 4 The base 100 has a first station 104 and a second station 105, and the adjusting table 200 is rotatably installed on the first station 104 in the first direction 101. The first station 104 is arranged to facilitate the positioning and installation of the adjusting table 200 on the base 100. Optionally, the second station can be installed with another work component, or can not be installed, which is not limited here.
[0071] Specifically, the first station 104 and the second station 105 are spaced apart along the second direction 102 to avoid interference with the angle adjustment of the adjusting table 200, and the structure is orderly and compactly distributed.
[0072] Specifically, the workpiece with a large mass is installed at the second work station 105, and the workpiece with a small mass is installed at the first work station 104.
[0073] In the conventional carrier, two angle degrees of freedom adjustment need to be realized by superposition of two adjustment modules, each adjustment module including a pair of main materials, the second adjustment module being installed at the output end of the first adjustment module, and the adjustment table 200 being installed at the output end of the second adjustment module, which leads to increase of the volume and complexity of the carrier, and the error affecting the angle precision is also accumulated and enlarged.
[0074] The angle adjustment carrier 10 provided by the application can realize relative angle adjustment of two lenses under the space degree of freedom, replace the complex mechanical hand adjustment mode in a certain range, has the characteristics of high module bearing capacity, easy adjustment, and high reliability when applied to the video monitoring field. At least two angles are adjusted by using a pair of main materials (the base 100 and the adjustment table 200), which reduces the intermediate links and error accumulation, has the characteristics of simple structure, high precision, and good reliability, can meet the demand of the adjustment platform of the 10-100 micrometer level for the 500g mass level, and expands the application scenarios under the condition of no multi-axis mechanical hand or high-precision slide table support.
[0075] In some embodiments, when the angle adjustment is completed, the two ends of the first adjustment rod 310 and the second adjustment rod 320 are respectively bonded and fixed on the base 100 and the adjustment table 200. Based on this, the optimal angle position of the adjustment table 200 obtained by fine adjustment can be long-term maintained. This is particularly important for application scenarios that require high-precision angle adjustment (such as optical equipment, precision measuring instruments, etc.), for example, to ensure that the state of the two lenses that have been focused will not change due to accidental movement, thereby ensuring the clarity and accuracy of the captured or monitored images.
[0076] In some embodiments, in combination with Figure 1 and Figure 2 , the angle adjustment carrier 10 further includes a rotation center shaft 340, the length direction of the rotation center shaft 340 is consistent with the first direction 101, the rotation center shaft 340 is fixedly installed on the base 100, and the adjustment table 200 is rotatably sleeved with the rotation center shaft 340. The rotation center shaft 340 serves as the fulcrum of the rotation of the adjustment table 200, which improves the stability and reliability of the adjustment table 200 during rotation. The rotation center shaft 340 can ensure that the adjustment table 200 rotates accurately around the first direction 101 during rotation, and reduces the error caused by factors such as mechanism gap and friction.
[0077] In one of the embodiments, in combination with Figure 2 and Figure 3The angle-adjusting base 10 further comprises an elastic body 350 sleeved on the rotating central shaft 340, and the elastic body 350 is located between the base 100 and the adjusting platform 200. The elastic body 350 separates the adjusting platform 200 and the base 100, and plays a role of stably supporting the adjusting platform 200 when the adjusting platform 200 rotates relative to the base 100, without causing the rotating central shaft 340 to deviate due to the extrusion of the elastic body 350 relative to the base 100.
[0078] Optionally, the elastic body 350 is a spring, a disc spring, a rubber pad or the like elastic object.
[0079] In one embodiment, in combination with Figure 2 and Figure 3 , the first adjusting rod 310 and the second adjusting rod 320 are spaced apart along the second direction 102, so that the line connecting the first adjusting rod 310 and the second adjusting rod 320 is the second direction 102, and the perpendicular line of the line is the third direction 103, and the rotation of the adjusting platform 200 around the second direction 102 or the third direction 103 is precisely controlled by the first adjusting rod 310 and the second adjusting rod 320.
[0080] In one embodiment, the first adjusting rod 310 and the second adjusting rod 320 are equidistant from the rotating central shaft 340 along the second direction 102, which on the one hand improves the structural symmetry and enhances the overall stability, and on the other hand simplifies the adjustment process and makes it easier to achieve consistent adjustment between the two, and when angle-adjusting around the second direction 102, it is more convenient to control the adjustment amount proportion of the two.
[0081] In one embodiment, the first adjusting rod 310 and the second adjusting rod 320 are equidistant from the rotating central shaft 340 along the third direction 103, which on the one hand improves the structural symmetry, uniformly distributes the load and enhances the overall stability, and on the other hand simplifies the adjustment process and makes it easier to achieve consistent adjustment between the two, and when angle-adjusting around the second direction 102, it is more convenient to control the adjustment amount proportion of the two, and improves the adjustment accuracy.
[0082] Specifically, the first adjusting rod 310, the second adjusting rod 320 and the rotating central shaft 340 form an isosceles triangle, and the line connecting the first adjusting rod 310 and the second adjusting rod 320 is the base of the isosceles triangle, so that when the first adjusting rod 310 and the second adjusting rod 320 are adjusted around the second direction 102, only the first adjusting rod 310 and the second adjusting rod 320 need to be adjusted by the same amount and in the same direction, without the need for complex calculation or multiple attempts, thereby simplifying the adjustment process.
[0083] In one embodiment, the distance between the first adjusting rod 310 and the rotation center axis 340 in the third direction 103 is greater than or equal to 1 / 2 of the size of the adjusting table 200 in the third direction 103. The distance between the first adjusting rod 310 and the rotation center axis 340 is large, so the same adjustment amount corresponds to a smaller angle of adjustment, which realizes fine adjustment of the angle and can achieve micron-level adjustment. For example, the angle adjustment table 10 is applied to the field of video monitoring. For the current double-lens fusion high-definition image / video output, the adjustment precision reaches the pixel level, and the stability precision reaches the pixel level, realizing pixel-level image coincidence.
[0084] In one embodiment, the distance between the first adjusting rod 310 and the rotation center axis 340 in the third direction 103 is less than or equal to 3 / 4 of the size of the adjusting table 200 in the third direction 103. One is to avoid excessive torque, and the other is to avoid being too close to the edge to reduce the connection strength.

The distance between the first adjusting rod 310 and the rotation center axis 340 is large, so the same adjustment amount corresponds to a smaller angle of adjustment, which realizes fine adjustment of the angle and can achieve micron-level adjustment.

One is to avoid excessive torque, and the other is to avoid being too close to the edge to reduce the connection strength.
[0089] In one embodiment, the distance between the second adjustment rod 320 and the rotation center axis 340 in the third direction 103 is greater than or equal to 1 / 2 of the size of the adjustment table 200 in the third direction 103. The distance between the second adjustment rod 320 and the rotation center axis 340 is large, so the same adjustment amount corresponds to a smaller adjustment angle, which achieves fine adjustment of the angle and can achieve micron-level adjustment.
[0090] In one embodiment, the distance between the second adjustment rod 320 and the rotation center axis 340 in the third direction 103 is less than or equal to 3 / 4 of the size of the adjustment table 200 in the third direction 103. This is to avoid excessive torque and to avoid being too close to the edge to reduce the connection strength.
[0091] In one embodiment, the distance between the second adjustment rod 320 and the edge of the adjustment table 200 in the third direction 103 is less than or equal to 3 times the diameter of the second adjustment rod 320 and greater than the radius of the second adjustment rod 320, so as to increase the distance between the second adjustment rod 320 and the rotation center axis 340 in the third direction 103 as much as possible.
[0092] In one embodiment, the distance between the second adjustment rod 320 and the rotation center axis 340 in the second direction 102 is greater than or equal to 1 / 3 of the size of the adjustment table 200 in the second direction 102.

[0094] In one embodiment, the distance between the second adjustment rod 320 and the edge of the adjustment table 200 in the second direction 102 is less than or equal to 3 times the diameter of the second adjustment rod 320 and greater than the radius of the second adjustment rod 320, so as to increase the distance between the second adjustment rod 320 and the rotation center axis 340 in the second direction 102 as much as possible.
[0095] In some embodiments, in combination with Figure 1 and Figure 2The angle-adjusting base 10 further comprises a first supporting rod 360, the length direction of the first supporting rod 360 is consistent with the first direction 101, one end of the first supporting rod 360 is fixedly connected to one of the base 100 and the adjusting table 200, and the other end of the first supporting rod 360 is movably inserted through the other of the base 100 and the adjusting table 200 and is in abutment with the other. The first supporting rod 360 can effectively transfer and disperse the weight of the adjusting table 200 and its load, and enhance the structural stability of the entire angle-adjusting base 10.
[0096] In some embodiments, the base 100 is provided with a connecting plate 110, and the angle-adjusting base 10 further comprises a third adjusting rod 410, the length direction of the third adjusting rod 410 is consistent with the second direction 102, one end of the third adjusting rod 410 is in abutment with one of the connecting plate 110 and the adjusting table 200, and the other end of the third adjusting rod 410 is adjustably connected to the other of the connecting plate 110 and the adjusting table 200. By adjusting the connection position, the third adjusting rod 410 can realize the rotation of the adjusting table 200 relative to the base 100 around the first direction 101, and realize the adjustment of three angles of freedom, so as to meet more complex adjustment requirements.
[0097] In some embodiments, in combination with Figures 1 to 3 One end of the third adjusting rod 410 is in abutment with the connecting plate 110, so as to limit the third adjusting rod 410 from continuously moving along the second direction 102 towards the adjusting table 200 relative to the connecting plate 110, and the other end of the third adjusting rod 410 is adjustably connected to the adjusting table 200. By adjusting the position, the third adjusting rod 410 can push the adjusting table 200 to rotate around the first direction 101, so as to realize the adjustment of the included angle between the base 100 and the adjusting table 200.
[0098] For example, the connecting plate 110 has a third through hole 111 extending along the first direction 101, the adjusting table 200 has a third threaded hole 204 extending along the first direction 101, one end of the third adjusting rod 410 is in abutment with the side of the connecting plate 110 away from the adjusting table 200, i.e., the head of the third adjusting rod 410 cannot pass through the third through hole 111, and the other end of the third adjusting rod 410 is inserted through the third through hole 111 and is threadedly connected to the third threaded hole 204. By means of the threaded connection, the position of the other end of the third adjusting rod 410 in the adjusting table 200 can be accurately adjusted, so that the included angle between the adjusting table 200 and the connecting plate 110 can be finely adjusted, thereby meeting the requirement of high-precision angle adjustment.
[0099] For example, the connecting plate 110 has a third through hole 111 extending along the first direction 101, the adjusting table 200 has a third clamping hole extending along the second direction 102, and one end of the third adjusting rod 410 abuts against the side of the connecting plate 110 away from the adjusting table 200, i.e., the head of the third adjusting rod 410 cannot pass through the third through hole 111. The other end of the third adjusting rod 410 passes through the third through hole 111 and is adjustably clamped in the third clamping hole.
[0100] It can be understood that the third adjusting rod 410 is adjustably mounted on the base 100, and can be connected by screwing, clamping, sliding, adjustably bonding, adjustably magnetic attraction, etc., which are not specifically limited herein.
[0101] In other embodiments, one end of the third adjusting rod 410 abuts against the adjusting table 200, and the other end is adjustably connected to the connecting plate 110, so that the angle between the base 100 and the adjusting table 200 formed by the first direction 101 can be adjusted. The third adjusting rod 410 is adjustably mounted on the connecting plate 110, which can be connected by screwing, clamping, sliding, adjustably bonding, adjustably magnetic attraction, etc., which are not specifically limited herein.

The second supporting rod 420 can effectively transmit and disperse the weight of the adjusting table 200 and its load, and enhance the structural stability of the entire angle adjusting table 10.
[0103] In one of the embodiments, in combination with Figure 2 The angle adjusting table 10 further comprises a second elastic member 430, the second elastic member 430 is arranged between the connecting plate 110 and the adjusting table 200 in compression in the second direction 102. The second elastic member 430 can play a buffering role when the adjusting table 200 is subjected to external impact or vibration, reducing the direct impact of the impact or vibration on the adjusting table 200 and its working components, and protecting them from damage. During the adjustment process, the second elastic member 430 can provide a certain supporting force to help the adjusting table 200 maintain a stable position and angle, prevent slight deviation or shaking caused by external factors, and thus improve the accuracy and stability of the adjustment. Further, for higher intensity vibration, the second elastic member 430 is combined with the second supporting rod 420 and the elastic body 350 to absorb the vibration.
