Description

Technical Field

[0001] This invention relates to the field of camera accessory technology, and more specifically, to a magnetic ball head and tripod head assembly. Background Technology

[0002] In the field of photography, the pan and tilt head is an essential support system. Almost every tripod uses a pan and tilt head. Based on their structural principles, pan and tilt heads can be categorized into ball heads, 3D heads, cantilever heads, and hydraulic heads, among others. Among the many choices for tripod heads, the ball head's advantages, such as quick positioning and easy locking, have made it a popular choice. Furthermore, ball heads are relatively cheaper and can be made smaller and lighter. Compared to other types of pan and tilt heads, ball heads can be made more compact and have lower production costs, resulting in the vast majority of portable tripods and pan and tilt heads on the market using a ball head design.

[0003] However, ball heads also have obvious drawbacks. Because they lock by controlling the contact surface and tightness of the rubber block at the bottom of the ball head via a locking knob, they are more prone to wear and tear and asynchronous locking action with increased use. Once the locking force decreases, the most direct manifestation is the "nodding" phenomenon of the ball head, a common problem encountered by long-time ball head users. Furthermore, when adjusting a fixed angle, the camera's weight can cause the ball head to tilt due to the reduced locking force of the locking knob on the ball head. The ball falls over quickly after losing its supporting force; in both of these situations, the camera fixed on the gimbal is very likely to be thrown off or heavily impacted onto the ball head base or other accessories, causing damage to the camera and economic loss. In addition, when the tripod is set at the right angle, fine adjustments are often needed to adjust the angle during composition and shooting. Once the locking device at the bottom of the tripod is released, the shooting angle will change significantly. This will also prevent the photographer from adjusting the shooting angle more precisely to achieve the perfect composition and shooting effect, thus wasting a lot of time to reset the tripod angle. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing ball heads, where the fixed camera quickly falls over when the locking device is lost, easily leading to camera damage. This invention provides a magnetic ball head and tripod head assembly. By introducing a magnetic component to form a preset and fixed magnetic attraction with the omnidirectional ball head, the ball head will not tip over rapidly under its own weight or the weight of the external accessories connected to the first fixing part, thus preventing damage to the external accessories. The magnetic fixation allows for better manual fine-tuning of the angle, making it easier to achieve perfect composition and shooting effects. Therefore, this invention optimizes the safety of using the ball head when freely adjusting and fixing the shooting angle, reduces the problem of damage to external accessories, and has excellent practical performance and broad market prospects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A magnetic spherical gimbal includes:

[0007] A swivel ball table, including the ball head and connecting handle;

[0008] The limiting seat includes a ball seat for accommodating a ball head, and a limiting member that movably abuts against the ball head and limits the rotation of the ball head within the ball seat;

[0009] Magnetic attachment, fixed inside the ball seat and attracting the ball head;

[0010] The first fixing part and the second fixing part are used for detachably connecting external accessories and are respectively connected to the connecting handle and the limiting seat.

[0011] It should be noted that the ball head of the universal ball table of the present invention is made of a magnetically pleasing metal material. A fixed attraction force is formed between the ball head and the ball seat through the magnetic suction component. The magnetic suction component can hold the ball head and provide a strong magnetic attraction force. So much so that when the limiting component reduces the contact and locking force with the ball head, the magnetic attraction force can play an auxiliary attraction and buffering role, which can provide a certain support for the ball head. The ball head will not tip over rapidly under its own weight or the weight of the external accessories connected to the first fixing part, thereby preventing the external accessories from being bumped or broken. In addition, the magnetic attraction force between the magnetic suction component and the ball head will not gradually decrease due to wear after long-term use, as is the contact damping of traditional rubber blocks and ball heads. The magnetic attraction force between the magnetic suction component and the ball head of the present invention can be maintained stably for a long time, with very good reliability and stability.

[0012] This invention features a simple structure. By introducing a magnetic suction component, a preset and fixed magnetic force is formed between the ball head and the gimbal. This magnetic force should be less than the maximum static friction between the limiting component and the ball head, and greater than the sliding friction between the limiting component and the ball head. This invention combines the advantages of multi-angle adjustment and fastening of the gimbal, overcoming the technical defect of existing ball heads that are prone to "nodding" after wear or loss of locking force, leading to damage to external accessories. The preset magnetic force of this invention is stable and exists. Combined with the movable abutment of the limiting component, the combination of the two optimizes the safety of the ball head when adjusting and fixing the shooting angle, reducing the problem of damage to external accessories. At the same time, when quick composition and shooting are required, after releasing the limiting component, the ball head will not change the camera's shooting angle significantly under the magnetic force of the magnetic suction component. The magnetic fixation allows for better manual fine-tuning of the angle, achieving perfect composition and shooting effects through fine-tuning. It has excellent practical performance and broad market prospects.

[0013] It should also be noted that the external accessories connected to the first fixing part and the second fixing part of the present invention include, but are not limited to, cameras, mobile phones, tripods, support rods, stabilizers and other types. By connecting the connecting handle and the limiting seat through the first fixing part and the second fixing part, different external accessories can be quickly assembled and disassembled, realizing the multi-functional use of the magnetic ball gimbal of the present invention.

[0014] Furthermore, the limiting member includes a first clamping block and a second clamping block located inside the ball seat and movable relative to each other, and a bidirectional screw with one end passing through the ball seat and threadedly connected to both the first clamping block and the second clamping block. When the bidirectional screw is rotated, the helical directions of the first clamping block and the second clamping block are opposite, and the first clamping block and the second clamping block move and abut against the ball head under the rotation of the bidirectional screw.

[0015] It should be noted that the limiting component for fixing the angle of the omnidirectional ball table in this invention achieves locking by clamping the ball head. Rotating the bidirectional screw clockwise or counterclockwise can cause the first clamping block and the second clamping block with opposite helical directions to move towards or away from each other. This principle is used to adjust whether the first clamping block and the second clamping block abut against the ball head, thereby fixing the rotation angle of the ball head. This fastening method of the limiting component of this invention has a simple structure and reliable and effective movement. In addition, rubber or plastic parts can be provided on the side of the first clamping block and the second clamping block that contacts the ball head.

[0016] Furthermore, the limiting component also includes an adjusting handle located at the other end of the bidirectional screw. The adjusting handle facilitates the application of force and reduces operational difficulty.

[0017] Furthermore, the magnetic attracting component includes an arc-shaped magnetic attracting ring and / or annular magnetic attracting ring distributed around the outer periphery of the ball head. Both the arc-shaped magnetic attracting ring and the annular magnetic attracting ring are composed of several magnetic blocks arranged in sequence. The side of the arc-shaped magnetic attracting ring and the annular magnetic attracting ring facing the ball head matches the spherical curvature of the ball head.

[0018] It should be noted that the number of magnetic components is not unique. A single arc-shaped magnetic ring or a ring-shaped magnetic ring can be set, or both arc-shaped and ring-shaped magnetic rings can be set at the same time. The arc-shaped or ring-shaped magnetic rings are composed of several magnetic blocks arranged in sequence. This can better adapt to the arc shape of the ball head, reduce the processing difficulty of each magnetic block, and reduce the difficulty of installing and fixing the arc-shaped or ring-shaped magnetic rings on the outside of the ball head.

[0019] Furthermore, the ball seat includes an annular seat surrounding the end of the ball head, and a cylindrical outer shell surrounding the annular seat; one end of the bidirectional screw passes through the cylindrical outer shell and is threadedly connected to the first clamping block and the second clamping block respectively, and the magnetic attractor is embedded in the annular seat and located between the cylindrical outer shell and the ball head.

[0020] It should be noted that the annular seat is cup-shaped and fitted onto the end of the ball head, providing a base for the ball head to rotate. A preferred configuration is a magnetic component that is annularly embedded within the annular seat. Alternatively, the magnetic component can be additionally arranged around the outer circumference of the ball head in the form of an arc-shaped magnetic ring and / or a circular magnetic ring, working together with the annular seat to form a rotating base for the ball head. Simultaneously, the magnetic component generates a uniform magnetic force on the ball head, optimizing the overall structural design. This provides both a good securing and limiting effect on the ball head and a uniform adsorption force, ensuring consistent damping during rotation and resulting in a better user experience and performance.

[0021] Furthermore, the bottom of the annular seat is provided with a truncated cone hole with a gradually increasing diameter. The first clamping block and the second clamping block move relative to each other within the range of the outer diameter of the bottom surface of the truncated cone hole. The outer periphery of the upper end face of the first clamping block and the second clamping block is provided with a chamfer parallel to the inner inclined surface of the truncated cone hole.

[0022] It should be noted that the annular seat and the limiting member cooperate with each other. A truncated cone hole is opened at the bottom of the annular seat, which limits the movement of the first clamping block and the second clamping block within the range of the outer diameter of the bottom surface of the truncated cone hole. The ball head is mounted in the annular seat, and the end of the ball head is exposed from the bottom surface of the truncated cone hole. The first clamping block and the second clamping block move and abut against the end of the ball head on the bottom surface of the truncated cone hole. Since the inner inclined surface of the truncated cone hole and the chamfer opened on the upper end surface of the first clamping block and the second clamping block form a contact fit, it can guide the movement of the first clamping block and the second clamping block on the one hand, and improve the stability of the movement of the first clamping block and the second clamping block on the other hand.

[0023] Furthermore, at least one clearance groove is provided at the end of the cylindrical outer shell, located at the end where the connecting handle extends out of the cylindrical outer shell. The clearance groove can increase the rotation angle of the omnidirectional ball table. Since the connecting handle is located above the ball head in the omnidirectional ball table, there is contact interference between the connecting handle and the cylindrical outer shell, limiting the rotation range of the connecting handle. When the clearance groove is provided at the upper end of the cylindrical outer shell, the connecting handle can avoid and rotate into the clearance groove during the rotation of the ball head, increasing the omnidirectional ball table's rotation angle and swing range.

[0024] Furthermore, the first fixing part includes a fixing plate fixed to the connecting handle, an adjusting plate that movably abuts against the fixing plate, and a first limiting screw rod with one end passing through the adjusting plate and threadedly connected to the fixing plate. The upper end surfaces of the fixing plate and the adjusting plate form an inverted trapezoidal groove with a small opening and a large bottom for engaging a camera quick-release plate. It should be noted that the width of the inverted trapezoidal groove is adjustable by the movement of the adjusting plate, thus adapting to quick-release plates of various sizes. Preferably, the first fixing part connected to the connecting handle is used for attaching external cameras and other accessories. In use, the connecting handle faces upwards, making it easier to rotate and adjust the angle during use.

[0025] Furthermore, the second fixing part includes a rotating platform with one end inserted into the ball seat and rotatably fastened to the lower end of the ball seat, and a second limiting screw rod with one end passing through the ball seat and movably abutting against the rotating platform; the second limiting screw rod is threadedly connected to the ball seat, and the bottom of the rotating platform is also provided with a mounting screw hole for threaded connection with the tripod. It should be noted that the mounting part of the tripod and other external accessories is provided with standard mounting bolts. After the rotating platform is fixed to the tripod, if it is necessary to adjust the shooting angle, the ball seat can be rotated, which will drive the universal ball table, limiting seat, first fixing part and other structures fixed relative to the ball seat to rotate relative to the rotating platform, so as to realize 360-degree angle adjustment with the axis of the ball seat as the center. By tightening the second limiting screw rod, the second limiting screw rod abuts against the rotating platform, restricting the relative rotation between the rotating platform and the ball seat. The structure is simple and effective.

[0026] A tripod head includes a tripod and the aforementioned magnetic ball head, with a second fixing part detachably threadedly connected to the tripod.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This invention utilizes a magnetic suction component to create a fixed attractive force between the ball head and the ball seat. The magnetic suction component effectively holds the ball head in place, providing a secure magnetic force. Even when the limiting component reduces the contact and locking force with the ball head, the magnetic force assists in the attraction and provides cushioning and damping, offering some support to the ball head. This prevents the ball head from rapidly tipping over under its own weight or the weight of the external attachment connected to the first fixing part, thus preventing damage to the external attachment. Furthermore, unlike the contact damping of traditional rubber blocks and ball heads, the magnetic force between the magnetic suction component and the ball head does not gradually decrease due to wear after prolonged use. The magnetic attraction between the magnetic attachment and the ball head in this invention can be maintained stably for a long time, exhibiting excellent reliability and stability. When quick composition and shooting are required, after releasing the limiting component, the ball head will not significantly change the camera's shooting angle under the magnetic attraction of the magnetic attachment. The magnetic fixation allows for better manual fine-tuning of the angle, achieving perfect composition and shooting effects through fine-tuning. This ensures the safety of using the ball head when freely adjusting and fixing the shooting angle, reduces the problem of damage to external accessories, and also reduces the difficulty of fine-tuning the angle during shooting, improving the shooting effect. It has excellent practical performance and broad market prospects. Attached Figure Description

[0038] Example 1

[0039] like Figures 1 to 3 As shown, a magnetic spherical gimbal includes:

[0040] The omnidirectional ball table 1 includes a ball head 11 and a connecting handle 12;

[0041] The limiting seat 2 includes a ball seat 21 for accommodating the ball head 11, and a limiting member 22 that movably abuts against the ball head 11 and limits the rotation of the ball head 11 within the ball seat 21;

[0042] The magnetic component 3 is fixed inside the ball seat 21 and attracts the ball head 11;

[0043] The first fixing part 4 and the second fixing part 5 are used for detachably connecting external accessories and are respectively connected to the connecting handle 12 and the limiting seat 2.

[0044] In this embodiment, the ball head 11 of the omnidirectional ball table 1 is made of a magnetically adsorbable metal material.

[0045] This embodiment has a simple structure. By introducing a magnetic suction component 3 to form a preset and fixed magnetic attraction force with the universal ball table 1, the magnetic attraction force is less than the maximum static friction force between the limiting component 22 and the ball head 11, and the magnetic attraction force is greater than or equal to the sliding friction force between the limiting component 22 and the ball head 11.

[0046] This embodiment combines the advantages of multi-angle adjustment and fastening of the gimbal 1, overcoming the technical defect of existing gimbals that are prone to "nodding" after wear or loss of locking force, leading to damage to external accessories. The preset magnetic attraction force in this embodiment is stable, and combined with the movable abutment limit of the limiting component 22, the combination of the two optimizes the safety of the gimbal when adjusting and fixing the shooting angle, reducing the problem of damage to external accessories. At the same time, when quick composition and shooting are required, the limiting component 22 can be released, and the ball head 11 will not change the shooting angle of the camera significantly under the magnetic attraction force of the magnetic component 3. The magnetic fixation can better realize manual fine-tuning of the angle, and achieve perfect composition and shooting effect by fine-tuning the angle. It has very good practical performance and broad market prospects.

[0047] In this embodiment, the first fixing part 4 is fixedly connected to the connecting handle 12 and is used to connect an external camera. The second fixing part 5 is connected to the limiting seat 2 and is used to connect an external tripod, support rod, or stabilizer. In use, the ball head 11 rotates in the ball seat 21, and the connecting handle 12 on the ball head 11 faces upward and can rotate and swing within a certain space. The first fixing part 4 connected to the connecting handle 12 connects to the external camera, enabling adjustment and rotation at different positions and angles. By connecting the connecting handle 12 and the limiting seat 2 through the first fixing part 4 and the second fixing part 5, the connecting handle 12 and the limiting seat 2 can be quickly disassembled and assembled, and different external accessories can be matched, realizing the multi-functional use of the magnetic ball head in this embodiment.

[0048] like Figures 2 to 3 As shown, the limiting member 22 includes a first clamping block 221 and a second clamping block 222 located inside the ball seat 21 and movable relative to each other, and a bidirectional screw 223 with one end passing through the ball seat 21 and threadedly connected to the first clamping block 221 and the second clamping block 222. When the bidirectional screw 223 is rotated, the helical directions of the first clamping block 221 and the second clamping block 222 are opposite, and the first clamping block 221 and the second clamping block 222 move and abut against the ball head 11 under the rotation of the bidirectional screw 223.

[0049] It should be noted that in this embodiment, the limiting member 22 used to fix the angle of the omnidirectional ball table 1 is locked by clamping the ball head 11. Rotating the bidirectional screw 223 clockwise or counterclockwise can cause the first clamping block 221 and the second clamping block 222 with opposite helical directions to move towards or away from each other. This principle is used to adjust whether the first clamping block 221 and the second clamping block 222 are in contact with the ball head 11, thereby fixing the rotation angle of the ball head 11. This fastening method of the limiting member 22 has a simple structure and reliable and effective movement.

[0050] In this embodiment, a rubber pad may be provided on the side of the first clamping block 221 and the second clamping block 222 that contacts the ball head, which can provide greater frictional resistance and have a better limiting effect.

[0051] like Figures 2 to 3 As shown, the limiting member 22 also includes an adjusting handle 224 located at the other end of the bidirectional screw 223. The adjusting handle 224 facilitates the application of force to rotate the bidirectional screw 223, reducing the difficulty of operation.

[0052] In this embodiment, the magnetic attractor 3 includes an arc-shaped magnetic ring 31 and an annular magnetic ring 32 distributed around the outer periphery of the ball head 11. Both the arc-shaped magnetic ring 31 and the annular magnetic ring 32 are composed of several magnetic blocks arranged sequentially. The side of the arc-shaped magnetic ring 31 and the annular magnetic ring 32 facing the ball head 11 matches the spherical curvature of the ball head 11. In this way, the magnetic attractor 3 can adapt to the arc shape of the ball head 11, reducing the processing difficulty of each magnetic block and the difficulty of installing and fixing the arc-shaped magnetic ring 31 or the annular magnetic ring 32 on the outside of the ball head 11.

[0053] like Figure 2 As shown, the ball seat 21 includes an annular seat 211 surrounding the end of the ball head 11, and a cylindrical outer shell 212 surrounding the outside of the annular seat 211; one end of the bidirectional screw 223 passes through the cylindrical outer shell 212 and is threadedly connected to the first clamping block 221 and the second clamping block 222 respectively.

[0054] In this embodiment, the annular magnetic ring 32 of the magnetic suction component 3 is embedded on the annular seat 211 and located between the columnar outer shell 212 and the ball head 11.

[0055] It should be noted that the annular seat 211 is cup-shaped and fitted onto the end of the ball head 11, providing a base for the ball head 11 to rotate. The annular magnetic ring 32 in the magnetic suction component 3 is embedded in the annular seat 211, and the arc-shaped magnetic ring 31 in the magnetic suction component 3 surrounds the outer circumference of the ball head 11. Together with the annular magnetic ring 32 in the annular seat 211, they form a base for the rotation of the ball head 11. At the same time, the magnetic suction component 3 generates a uniform magnetic attraction force on the ball head 11, optimizing the overall structural design. Firstly, it has a good fastening and limiting effect on the ball head 11, and secondly, it can form a uniform attraction force on the ball head 11, so that the damping effect is the same when the ball head 11 rotates, resulting in a better feel and performance.

[0056] like Figure 2 As shown, the bottom of the annular seat 211 is provided with a truncated cone hole 2110 with a gradually increasing diameter. The first clamping block 221 and the second clamping block 222 move relative to each other within the range of the outer diameter of the bottom surface of the truncated cone hole 2110. The outer periphery of the upper end face of the first clamping block 221 and the second clamping block 222 is provided with a chamfer parallel to the inner inclined surface of the truncated cone hole 2110.

[0057] It should be noted that the annular seat 211 and the limiting member 22 cooperate with each other. A frustum hole 2110 is opened at the bottom of the annular seat 211, which limits the movement of the first clamping block 221 and the second clamping block 222 within the range of the outer diameter of the bottom surface of the frustum hole 2110. The ball head 11 is mounted in the annular seat 211, and the end of the ball head 11 is exposed from the bottom surface of the frustum hole 2110. The first clamping block 221 and the second clamping block 222 move and abut against the end of the ball head 11 on the bottom surface of the frustum hole 2110. Since the inner inclined surface of the frustum hole 2110 and the chamfer opened on the upper end surface of the first clamping block 221 and the second clamping block 222 form a contact fit, it can guide the movement of the first clamping block 221 and the second clamping block 222 on the one hand, and improve the stability of the movement of the first clamping block 221 and the second clamping block 222 on the other hand.

[0058] like Figure 3 As shown, a clearance groove 2121 is provided at the end of the cylindrical outer shell 212, and the clearance groove 2121 is located at the end of the connecting handle 12 that extends out of the cylindrical outer shell 212. In this embodiment, the arc-shaped magnetic ring 31 in the magnetic suction component 3 is located at the end of the cylindrical outer shell 212 where the clearance groove 2121 is provided, and the arc-shaped magnetic ring 31 surrounds the outer periphery of the ball head 11 and forms a clearance at the clearance groove 2121.

[0059] The clearance groove 2121 can increase the rotation angle of the omnidirectional ball table 1. Since the ball head 11 in the omnidirectional ball table 1 is provided with a connecting handle 12, there is contact interference between the connecting handle 12 and the cylindrical shell 212, and the rotation range of the connecting handle 12 is limited. When the clearance groove 2121 is opened at the upper end of the cylindrical shell 212, the connecting handle 12 can avoid and rotate into the clearance groove 2121 during the rotation of the ball head 11, thereby increasing the rotation angle and swing range of the omnidirectional ball table 1.

[0060] The advantage of this embodiment lies in the fixed attraction force formed between the ball head 11 and the ball seat 21 by the magnetic suction component 3. The magnetic suction component 3 can attract the ball head 11 and provide a strong magnetic attraction force, so that when the limiting component 22 reduces the contact and locking force with the ball head 11, the magnetic attraction force can play an auxiliary attraction and buffering role, providing a certain support for the ball head 11. The ball head 11 will not tip over rapidly under its own weight or the weight of the external accessories connected to the first fixing part 4, thereby preventing the external accessories from being bumped or broken. At the same time, when quick composition and shooting are required... When shooting, the limiting piece 22 is released. Under the magnetic attraction of the magnetic component 3, the ball head 11 will not change the shooting angle of the camera significantly. The magnetic fixation can better realize manual fine-tuning of the angle, and achieve perfect composition and shooting effect by fine-tuning the angle. In addition, the magnetic attraction between the magnetic component 3 and the ball head 11 will not be like the contact damping of the traditional rubber block and the ball head 11, which will gradually reduce the damping due to wear after long-term use. In this embodiment, the magnetic attraction between the magnetic component 3 and the ball head 11 can be maintained stably for a long time, with very good reliability and stability.

[0061] Example 2

[0062] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0063] In this embodiment, the first fixing part 4 is fixedly connected to the connecting handle 12 and is used to connect an external tripod, support rod, or stabilizer. The second fixing part 5 is connected to the limiting seat 2 and is used to connect an external camera. In use, the ball head 11 rotates in the ball seat 21, with the connecting handle 12 of the ball head 11 facing downwards. The first fixing part 4 connected to the connecting handle 12 is used to connect an external tripod, support rod, or stabilizer, and the second fixing part 5 connected to the limiting seat 2 is used to connect the camera. The position and angle of the camera are adjusted by swinging the limiting seat 2, allowing the limiting seat 2 to swing around the ball head 11 within a certain spatial range. Through the connection of the connecting handle 12 and the limiting seat 2 via the first fixing part 4 and the second fixing part 5, the connecting handle 12 and the limiting seat 2 can be quickly disassembled and assembled, and different external accessories can be used, realizing the multi-functional use of the magnetic ball head in this embodiment.

[0064] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0065] Example 3

[0066] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0067] like Figure 4As shown, the first fixing part 4 includes a fixing plate 41 fixed to the connecting handle 12, an adjusting plate 42 movably abutting against the fixing plate 41, and a first limiting screw rod 43 with one end passing through the adjusting plate 42 and threadedly connected to the fixing plate 41. The upper end surfaces of the fixing plate 41 and the adjusting plate 42 form an inverted trapezoidal groove 40 with a small opening and a large bottom for snapping into a camera quick-release plate. It should be noted that the width of the inverted trapezoidal groove 40 can be adjusted by the movement of the adjusting plate 42, so it can be adapted to quick-release plates of various sizes. In this embodiment, the first fixing part 4 connected to the connecting handle 12 is preferably used for external cameras and other accessories. When in use, the connecting handle 12 faces upward, so that this embodiment is more convenient to rotate and adjust the angle during use.

[0068] like Figure 3 and Figure 5 As shown, the second fixing part 5 includes a rotating platform 51 with one end inserted into the ball seat 21 and rotatably fastened to the lower end of the ball seat 21, and a second limiting screw rod 52 with one end passing through the ball seat 21 and movably abutting against the rotating platform 51; the second limiting screw rod 52 is threadedly connected to the ball seat 21, and the bottom of the rotating platform 51 is also provided with a mounting screw hole 53 for threaded connection with the tripod. It should be noted that the mounting parts of the tripod and other external accessories are equipped with standard mounting bolts. In this embodiment, after the rotating platform 51 is fixed to the tripod, if it is necessary to adjust the shooting angle, the ball seat 21 can be rotated to drive the universal ball table 1, the limiting seat 2, the first fixing part 4 and other structures fixed relative to the ball seat 21 to rotate relative to the rotating platform 51, so as to achieve 360-degree angle adjustment with the axis of the ball seat 21 as the center. By tightening the second limiting screw rod 52, the second limiting screw rod 52 abuts against the rotating platform 51, restricting the relative rotation between the rotating platform 51 and the ball seat 21. The structure is simple and effective.

[0069] In this embodiment, the rotating platform 51 is rotatably fastened to the cylindrical shell 212, and the second limiting rod 21 passes through the cylindrical shell 212 and moves to abut against the part of the rotating platform 51 that extends into the cylindrical shell 212.

[0070] The other structures and principles of this embodiment are the same as those of Embodiment 1.
