Description

Technical Field

[0001] This utility model relates to the technical field of photographic equipment, and in particular to a camera gimbal with an adjustable safety block position. Background Technology

[0002] During the photography process, a camera tripod is generally used to mount and stabilize the camera, camcorder, and other photography equipment to prevent blurry images caused by hand tremors or equipment movement during shooting.

[0003] In some related technologies, such as patent publication number CN218268044U, a photographic gimbal with an adjustable safety block position is disclosed. This includes a gimbal body, a safety block, and a displacement adjustment mechanism. The gimbal body has a mounting groove for mounting a quick-release plate and a movable groove extending through the mounting groove. The safety block is movably mounted on the gimbal body and extends upwards along the movable groove onto the surface of the mounting groove. The displacement adjustment mechanism is located between the safety block and the gimbal body, used to drive the safety block to move within the movable groove. The displacement adjustment mechanism includes a swing arm rotatably mounted on the gimbal body, and the safety block is connected to the swing arm. The displacement adjustment mechanism also includes a corner positioning structure located between the safety block and the gimbal body. The corner positioning structure includes at least two positioning grooves circumferentially distributed around the rotation axis of the swing arm, and the safety block is elastically connected to a positioning protrusion capable of extending into any of the positioning grooves. The main body of the gimbal has a platform section located in the movable slot, a positioning slot located in the platform section, a safety block with a channel facing the platform section, a positioning protrusion that is a ball head accommodated in the channel, and a spring member that abuts against the ball head in the channel so that the ball head extends out of the narrow opening and enters the positioning slot.

[0004] To accommodate different sizes of quick-release plates, when the position of the safety block needs to be adjusted, the first screw is loosened first, and then the swing arm is driven to rotate. At this time, the ball head leaves the first positioning groove and enters the upper surface of the platform, causing the spring to be in a compressed state. When the swing arm rotates until the ball head aligns with the second positioning groove, the spring returns to its original shape, pushing the ball head into the positioning groove so that the swing arm rotates to the required angle position. However, this solution has a problem: the first screw needs to be loosened first, meaning that the user needs to use a tool (such as a screwdriver) or brute force to loosen the first screw before each adjustment of the safety block position, which is not convenient.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0037] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0038] To address the problem that existing camera pan-tilt heads are not convenient to operate when changing the position of the safety block 34, this utility model provides a camera pan-tilt head with an adjustable safety block position.

[0039] The following describes in detail the specific structure of a camera pan-tilt unit with an adjustable safety block position provided by an embodiment of this utility model, according to the appendix. Figure 1-4 As shown, the specific structure of the camera pan-tilt unit with adjustable safety block position includes a pan-tilt unit body 1, a position adjustment component 2, and a locking component 3.

[0040] The main body 1 of the gimbal has a rotating cavity 11 and multiple positioning holes 12.

[0041] Specifically, the pan-tilt body 1 is the basic structure of the entire adjustable safety block camera pan-tilt head, providing stable support for the camera equipment. The camera equipment is mounted on the quick-release plate, which is then assembled onto the pan-tilt body 1. The support of the pan-tilt body 1 ensures the stability of the camera equipment during use, preventing it from shaking or shifting due to external forces. The rotating cavity 11 accommodates the rotating part 21, allowing it to rotate freely within it, while providing the necessary space and guidance to ensure smoother and more precise movement of the rotating part 21. The spacing of the positioning holes 12 allows the safety pin 34 to be switched between multiple preset positions. That is, depending on the type of quick-release plate, the position of the safety pin 34 is adjusted by inserting it through one of the positioning holes 12.

[0042] It is understood that there are two positioning holes 12 in this embodiment of the present invention, which correspond to quick-release plates of different specifications, such as the locking holes of DJI quick-release plates and Manfrotto quick-release plates.

[0043] according to Figures 1-3 As shown, the position adjustment assembly 2 includes a rotating part 21 and a first elastic member 23; the rotating part 21 is rotatably disposed in the rotating cavity 11, and a protrusion 22 is provided at the end of the rotating part 21; the first elastic member 23 is sleeved on the outer periphery of the rotating part 21, and the first elastic member 23 is built into the rotating cavity 11 along with the rotating part 21, one end of the first elastic member 23 abuts against the protrusion 22, and the other end of the first elastic member 23 abuts against the bottom of the rotating cavity 11, so that the first elastic member 23 is in a compressed state.

[0044] Specifically, the rotating part 21 can rotate freely about its axis within the rotating cavity 11. A protrusion 22 is provided at the end of the rotating part 21, which abuts against a first elastic member 23. The first elastic member 23 is sleeved on the outer periphery of the rotating part 21 and is housed within the rotating cavity 11 along with the rotating part 21. By abutting one end of the first elastic member 23 against the protrusion 22 at the end of the rotating part 21 and the other end against the bottom of the rotating cavity 11, the first elastic member 23 provides an elastic force to push the rotating part 21 back to its initial position.

[0045] During operation, the rotating part 21 is in its initial position, while the first elastic element 23 is in a naturally extended or slightly compressed state. At this time, the protrusion 22 of the rotating part 21 abuts against one end of the first elastic element 23, and the other end of the first elastic element 23 abuts against the bottom of the rotating cavity 11. The elastic force of the first elastic element 23 keeps the rotating part 21 in its current position, preventing it from rising or falling arbitrarily due to external forces. When the position of the rotating part 21 needs to be adjusted, the user can manually pull the rotating part 21. During the pulling process, the protrusion 22 of the rotating part 21 compresses the first elastic element 23, storing elastic potential energy. Due to the elastic force of the first elastic element 23, the rotating part 21 experiences a certain resistance during rotation, which helps the user to more precisely control the rotation angle. When the rotating part 21 rotates to the desired position, the user releases the rotating part 21. At this time, the first elastic element 23 releases elastic potential energy during the process of restoring its original shape, pushing the protrusion 22 of the rotating part 21 back to the initial position or keeping it in the current position. Due to the elastic force of the first elastic element 23, the rotating part 21 will be stably kept in the new position and will not be easily moved by external force.

[0046] according to Figure 3As shown, the locking assembly 3 includes a safety pin 34, a pulling part 33, and a swing arm 31. The pulling part 33 is detachably disposed at the bottom of the rotating part 21 and can drive the rotating part 21 to move axially along the rotating cavity 11. One end of the swing arm 31 is connected to the pulling part 33. The safety pin 34 is fixed vertically to the other end of the swing arm 31. The first elastic member 23 can drive the safety pin 34 to pass through the positioning holes 12 at different positions to position different types of quick release plates.

[0047] Specifically, the pulling part 33 is detachably disposed at the bottom of the rotating part 21 for manually driving the rotating part 21 to move axially along the rotating cavity 11. The movement of the pulling part 33 drives the movement of the safety pin 34 through the swing arm 31. One end of the swing arm 31 is connected to the pulling part 33, and the other end is connected to the safety pin 34. The function of the swing arm 31 is to convert the lifting and lowering movement of the pulling part 33 into the lifting and lowering movement of the safety pin 34. At the same time, when the rotating part 21 is rotating, the safety pin 34 is driven to rotate along with it through the swing arm 31.

[0048] In the initial state, the safety pin 34 passes through one of the positioning holes 12 on the gimbal body 1, locking the rotating part 21 in its current position. When the position of the rotating part 21 needs to be adjusted, the user manually pulls the pulling part 33 downwards. The downward movement of the pulling part 33 drives the safety pin 34 downwards via the swing arm 31, causing the safety pin 34 to disengage from the positioning hole 12. At the same time, the first elastic element 23 is compressed, storing elastic potential energy. At this time, the rotating part 21 can rotate freely. After the safety pin 34 disengages from one of the positioning holes 12, the user can freely rotate the rotating part 21 to adjust it to the desired position. For example, rotating the rotating part 21 until the end of the safety pin 34 faces the other positioning hole 12. Because the first elastic element 23 is compressed, when the rotating part 21 is adjusted to the desired position, so that the safety pin 34 is directly below the other positioning hole 12, the user releases the pulling part 33, and the first elastic element 23... During the process of restoring the original shape, elastic potential energy is released to push the protrusion 22 upward and move it. At the same time, the pulling part 33 moves upward. When the pulling part 33 moves upward again, it drives the safety post 34 upward through the swing arm 31 until the safety post 34 passes through another positioning hole 12. In this way, the position of the safety post 34 is adjusted. With this setting, through the cooperation of the safety post 34 and the positioning hole 12, the rotating part 21 can be precisely locked in the required position to prevent it from moving arbitrarily due to external force. Moreover, the user can change the position of the safety post 34 simply by pulling the pulling part 33 and rotating the pulling part 33. The entire operation of changing the position of the safety post 34 is relatively simple and quick.

[0049] It is understood that the first elastic element 23 in this embodiment of the present invention is a spring.

[0050] according to Figure 3As shown, in some specific embodiments, the bottom of the rotating cavity 11 is provided with a guide hole 13, and the rotating part 21 is movably disposed in the guide hole 13; the outer side of the rotating part 21 is transitionally fitted with the hole wall of the guide hole 13.

[0051] Specifically, the guide hole 13 extends through the bottom of the rotating cavity 11, serving as the moving channel for the rotating part 21. Since the size of the guide hole 13 matches the outer diameter of the rotating part 21, it ensures that the rotating part 21 can move freely axially within the guide hole 13 while maintaining a certain fitting accuracy. The outer side of the rotating part 21 and the hole wall of the guide hole 13 adopt a transition fit. Since the transition fit is a fit method between clearance fit and interference fit, it allows the rotating part 21 to have a certain amount of room to move within the guide hole 13, but without excessive clearance. Thus, the hole wall of the guide hole 13 provides precise guidance to the outer side of the rotating part 21, ensuring that the rotating part 21 remains stable and accurate during rotation and axial movement.

[0052] For example, when the user drives the rotating part 21 to move axially along the rotating cavity 11 by pulling part 33, the transition fit between the outer side of the rotating part 21 and the hole wall of the guide hole 13 ensures the smoothness and accuracy of the movement. The hole wall of the guide hole 13 guides the outer side of the rotating part 21, preventing the rotating part 21 from deviating or getting stuck during the movement.

[0053] In a further embodiment, the outer diameter of the end face of the pulling part 33 facing the rotating part 21 is larger than the inner diameter of the guide hole 13.

[0054] Specifically, since the outer diameter of the end face of the pulling part 33 facing the rotating part 21 is larger than the outer diameter of the guide hole 13, the pulling part 33 cannot enter the rotating cavity 11 through the guide hole 13. This arrangement can prevent the pulling part 33 from accidentally entering the rotating cavity 11 during operation, thus avoiding interference or damage between the pulling part 33 and other components in the rotating cavity 11. In this way, when the first elastic member 23 rises to the bottom of the gimbal column when the rotating part 21 is in contact with the bottom of the pulling part 33, it prevents the pulling part 33 from directly extending into the rotating cavity 11.

[0055] Furthermore, since the outer diameter of the upper end face of the pulling part 33 is larger than the inner diameter of the guide hole 13, it means that the end face of the pulling part 33 forms a physical limit at the opening of the guide hole 13. When the safety pin 34 rises under the push of the first elastic member 23, the swing arm 31 will drive the pulling part 33 to move upward. Since the outer diameter of the end face of the pulling part 33 is larger than the inner diameter of the guide hole 13, the end face of the pulling part 33 will contact the opening of the guide hole 13. At this time, the rising height of the pulling part 33 can be limited to ensure that the safety pin 34 rises to the specified height.

[0056] In some specific embodiments, the outer side of the safety post 34 transitions into the wall of the positioning hole 12.

[0057] Specifically, the transition fit is a type of fit between clearance fit and interference fit. In this fit, there is a certain clearance between the outer diameter of the safety pin 34 and the inner diameter of the positioning hole 12, but this clearance is very small. This design allows the safety pin 34 some room to move within the positioning hole 12 without creating an excessive clearance, thus ensuring the tightness and stability of the fit. Therefore, by using a transition fit between the outer side of the safety pin 34 and the wall of the positioning hole 12, a tight fit is ensured within the positioning hole 12. This tight fit allows the safety pin 34 to stably penetrate the positioning hole 12, preventing radial wobbling after penetrating one of the positioning holes 12.

[0058] It should be noted that although the transition fit is relatively tight, there is still a certain gap, which allows the safety pin 34 to smoothly disengage from the positioning hole 12 during unlocking. This moderate gap reduces friction during unlocking, making the unlocking operation smoother.

[0059] according to Figure 4 As shown, in some specific embodiments, the rotating part 21 has a fixing hole 331, and the pulling part 33 has a locking hole 332 that is connected to the fixing hole 331. The rotating part 21 also includes a locking member 32, which is detachably inserted into both the locking hole 332 and the fixing hole 331.

[0060] Specifically, the rotating part 21 has a fixing hole 331 at its end, which is used to cooperate with the locking hole 332 of the pulling part 33 to fix the pulling part 33. The pulling part 33 is detachably disposed at the bottom of the rotating part 21. Specifically, the pulling part 33 has a through locking hole 332, which corresponds to and communicates with the fixing hole 331 of the rotating part 21. The locking member 32 is a key component for fixing the pulling part 33. By detachably inserting the locking member 32 into both the locking hole 332 and the fixing hole 331, the fixing and disassembly of the pulling part 33 can be achieved.

[0061] In normal operation, the locking element 32 is simultaneously inserted into both the locking hole 332 and the fixing hole 331, fixing the pulling part 33 to the bottom of the rotating part 21. Therefore, the rotating part 21 and the pulling part 33 are tightly connected by the locking element 32, forming a single unit, ensuring that the pulling part 33 will not loosen or fall off during operation. When it is necessary to disassemble the pulling part 33, the user manually twists the locking element 32 until it is removed. Once the locking element 32 is removed, the connection between the pulling part 33 and the rotating part 21 is released, and the pulling part 33 can be detached from the bottom of the rotating part 21. This design makes the disassembly and replacement of the pulling part 33 very convenient. Users can easily replace the pulling part 33 as needed, or quickly disassemble the component during maintenance. Conversely, when the pull part 33 needs to be reinstalled, the user aligns the pull part 33 with the bottom of the rotating part 21, so that the locking hole 332 and the fixing hole 331 are connected. Then, the user inserts the locking member 32 into both the locking hole 332 and the fixing hole 331 at the same time. The pull part 33 is fixed by the insertion of the locking member 32. The insertion of the locking member 32 ensures a tight connection between the pull part 33 and the rotating part 21, so that the pull part 33 can stably drive the rotating part 21 to move axially during operation.

[0062] It is understood that the fixing hole 331 in this embodiment of the present invention is a threaded hole, and the locking member 32 is a bolt. The bolt passes through the locking port and is inserted into the threaded hole, and is threadedly connected to the threaded hole.

[0063] according to Figures 5-11 As shown, in some specific embodiments, the pan-tilt body 1 is provided with a first movable cavity 14 and a second movable cavity 15; the camera pan-tilt with adjustable safety block position also includes a clamping assembly 4 and a width adjustment assembly 5; the clamping assembly 4 is movably disposed in the first movable cavity 14, and the width adjustment assembly 5 is disposed in the second movable cavity 15, and the width adjustment assembly 5 can move closer to or further away from the clamping assembly 4; the width adjustment assembly 5 includes a first clamping part 51, a second elastic member 52, a connecting structure 54, and a swing member 53; the first clamping part 51 is movably disposed in the second movable cavity 15. Inside, one end of the second elastic member 52 abuts against the cavity wall of the second movable cavity 15, and the other end of the second elastic member 52 abuts against the first clamping part 51; the swing member 53 is rotatably connected to one end of the connecting structure 54, and the other end of the connecting structure 54 is connected to the cavity wall of the first movable cavity 14; the swing member 53 is provided with several pressing surfaces, and the distance between each pressing surface and the cavity wall of the second movable cavity 15 is different; the swing member 53 rotates until one of its pressing surfaces abuts against the outer side of the first clamping part 51, so as to push the first clamping part 51 to move to squeeze the second elastic member 52.

[0064] Specifically, the clamping component 4 is movably disposed within the first movable cavity 14 and can move toward or away from the width adjustment component 5. The width adjustment component 5 is movably disposed within the second movable cavity 15 and can move toward or away from the clamping component 4. Thus, in the initial state, the distance between the clamping component 4 and the width adjustment component 5 is pre-adjusted according to the width of the quick-release plate. When the clamping component 4 is in the clamping state, the quick-release plate can be smoothly inserted between the clamping component 4 and the first clamping part 51. After the quick-release plate is inserted, the clamping component 4 and the width adjustment component 5 move closer to each other, causing the distance between the clamping component 4 and the width adjustment component 5 to gradually decrease, and finally the quick-release plate is tightly clamped between the two.

[0065] The function of the width adjustment component 5 is to change the distance between the clamping component 4 and the first clamping part 51 by adjusting the position of the first clamping part 51, thereby adapting to quick-release plates of different widths. The following is a detailed explanation of the operating principle of the width adjustment component 5: In the initial state, one of the pressing surfaces of the swing member 53 abuts against the outer side of the first clamping part 51, and the first clamping part 51 is in the initial position. The distance between the clamping assembly 4 and the first clamping part 51 is pre-adjusted according to the width of the quick-release plate. The quick-release plate is inserted between the clamping assembly 4 and the first clamping part 51. By rotating the swing member 53, one of the pressing surfaces of the swing member 53 abuts against the outer side of the first clamping part 51. Since the distances between different pressing surfaces and the cavity wall of the second movable cavity 15 are different, the first clamping part 51 will be pushed to different positions in the second movable cavity 15. When one of the pressing surfaces pushes the first clamping part 51 closer to the clamping assembly 4, the first clamping part 51 squeezes the second elastic member 52, and at the same time controls the clamping assembly 4 to move along the direction of the first clamping part 51 until the quick-release plate can be stably clamped. When replacing quick-release plates of other widths, rotate the swing member 53 again so that the other side of the swing member 53 abuts against the outer side of the first clamping part 51. Since the distance between the different pushing surfaces and the cavity wall of the second movable cavity 15 is different, the first clamping part 51 will be pushed to different positions, thereby changing the distance between the clamping assembly 4 and the first clamping part 51. Then, through cooperation with the clamping assembly 4, until the replaced quick-release plate can be stably clamped, the replacement of the quick-release plate is completed. In this way, quick-release plates of different widths can be quickly and stably fixed. At the same time, the whole operation process is relatively simple, which improves the versatility and convenience of the camera pan-tilt head with adjustable safety block position.

[0066] It is understood that the aforementioned pressing surfaces include a first pressing surface 531a, a second pressing surface 531b, and a third pressing surface 531c.

[0067] It should be noted that when the first clamping part 51 is pushed, the second elastic member 52 is compressed, generating an elastic force. This elastic force is transmitted to the pushing surface of the swing member 53 through the first clamping part 51, so that the outer side of the first clamping part 51 is always in contact with the pushing surface of the swing member 53. Since the outer side of the first clamping part 51 is in close contact with the pushing surface, the swing member 53 cannot rotate freely, thereby ensuring that the quick release plate can be fixed.

[0068] according to Figure 8 As shown, in some specific embodiments, an arc surface 534 is provided between adjacent pressing surfaces.

[0069] Specifically, by providing an arc surface 534 between adjacent pressing surfaces, the contact between the pressing surface and the outer side of the first clamping part 51 is smoother during the rotation of the swing member 53, thereby reducing friction between them, reducing wear, and extending the service life of the component. The smooth transition of the arc surface 534 avoids the possible jamming phenomenon when switching between the pressing surface and the first clamping part 51, ensuring smoother rotation of the swing member 53. For example, when the operating part 533 rotates the pressing part 532, causing one pressing surface of the pressing part 532 to switch to another pressing surface abutting against the outer side of the first clamping part 51, the arc surface 534 between the two pressing surfaces ensures a smoother transition during the contact between the other pressing surface and the outer side of the first clamping part 51.

[0070] according to Figure 6 As shown, in some specific embodiments, the connecting structure 54 includes a rotating shaft 541 and a connecting shaft 542; the swing member 53 is rotatably connected to both ends of the rotating shaft 541, one end of the connecting shaft 542 is connected to the outside of the rotating shaft 541, and the other end of the connecting shaft 542 is detachably connected to the cavity wall of the second movable cavity 15; the axial direction of the rotating shaft 541 is perpendicular to the axial direction of the connecting shaft 542.

[0071] Specifically, the two ends of the swing member 53 are rotatably connected to the rotating shaft 541, allowing the swing member 53 to rotate around the rotating shaft 541. One end of the connecting shaft 542 is connected to the outside of the rotating shaft 541, and the other end is detachably connected to the cavity wall of the second movable cavity 15. This arrangement allows the connecting shaft 542 to fix the position of the rotating shaft 541 while allowing the swing member 53 to rotate. The swing member 53 is rotatably connected to the rotating shaft 541 at both ends, allowing it to rotate freely around the axial direction of the rotating shaft 541. This rotatable connection allows the swing member 53 to abut against the outside of the first clamping part 51 through one of its pressing surfaces, thereby pushing the first clamping part 51 to move. Since the axial direction of the rotating shaft 541 is perpendicular to the axial direction of the connecting shaft 542, the rotation direction of the swing member 53 is independent of the fixing direction of the connecting shaft 542, thus ensuring that the swing member 53 is not restricted by the connecting shaft 542 during rotation and can freely adjust its angle.

[0072] One end of the connecting shaft 542 is connected to the outside of the rotating shaft 541, and the other end is detachably connected to the cavity wall of the second movable cavity 15. This connection method allows the connecting shaft 542 to fix the position of the rotating shaft 541, ensuring the stability of the rotating shaft 541 within the second movable cavity 15. The detachable connection between the connecting shaft 542 and the cavity wall of the second movable cavity 15 provides convenience for installation and maintenance. For example, when it is necessary to disassemble or replace the swing component 53, the connecting shaft 542 can be easily removed from the cavity wall, thereby facilitating the removal of the swing component 53 and the rotating shaft 541.

[0073] It is understood that the cavity wall of the second movable cavity 15 in this embodiment of the present invention is provided with a screw hole, and the end of the connecting shaft 542 facing the cavity wall of the second movable cavity 15 is provided with an external thread. In this way, the connecting shaft 542 is fixed by inserting the end of the connecting shaft 542 into the screw hole.

[0074] according to Figure 7 As shown, in some specific embodiments, a guide member 55 is provided in the second active cavity 15, and a guide cavity 511 is recessed in the first clamping part 51, with the guide member 55 passing through the guide cavity 511; one end of the second elastic member 52 abuts against the outer side of the guide member 55, and the other end of the second elastic member 52 abuts against the cavity wall of the guide cavity 511.

[0075] Specifically, the guide member 55 is disposed within the second movable cavity 15, thereby guiding the movement direction of the first clamping part 51. The guide cavity 511 is recessed within the first clamping part 51, cooperating with the guide member 55 to ensure that the first clamping part 51 can move along a predetermined trajectory. One end of the second elastic member 52 abuts against the outer side of the guide member 55, and the other end abuts against the cavity wall of the guide cavity 511, providing elastic force to the cavity wall of the guide cavity 511 of the first clamping part 51. By rotating the swing member 53, one of its pressing surfaces abuts against the outer side of the first clamping part 51, thereby pushing the first clamping part 51 to move. During the movement of the first clamping part 51, the guide member 55 slides within the guide cavity 511, ensuring that the first clamping part 51 moves smoothly along the predetermined trajectory. Thus, the movement trajectory of the first clamping part 51 is more precise under the guidance of the guide member 55, avoiding large deviations and wobbling of the first clamping part 51 during its movement within the second movable cavity 15.

[0076] It should be noted that the guide member 55 of this utility model embodiment has a spring hole recessed on the side facing the first clamping part 51, and the second elastic member 52 passes through the spring hole. The spring hole provides installation space for the second elastic member 52, and also ensures that the second elastic member 52 will not shift or fall off when it is in a compressed or extended state.

[0077] according to Figure 8 As shown, in some specific embodiments, the swing member 53 includes an integrally formed operating part 533 and a pushing part 532; the pushing part 532 is rotatably connected to one end of the connecting structure 54, and each pushing surface is disposed on the outer side of the pushing part 532.

[0078] Specifically, the operating part 533 is part of the swing member 53, which facilitates the user to push the entire swing member 53 to rotate. It can be understood that the operating part 533 is a handle that is easy for the user to grip. Thus, the user can manually operate the operating part 533 to make the entire pressing part 532 rotate around the axis of the rotation shaft 541, thereby adjusting the specified pressing surface to abut against the outer side of the first clamping part 51.

[0079] In some specific embodiments, the clamping assembly 4 includes a second clamping part 41, a pushing part 42, and a driving structure 43; the second clamping part 41 is rotatably disposed in the first movable cavity 14 and is disposed opposite to the first clamping part 51, and the pushing part 42 is disposed in the first movable cavity 14; the second clamping part 41 is provided with a first inclined surface 411, and the pushing part 42 is provided with a second inclined surface 421, and the first inclined surface 411 and the second inclined surface 421 are disposed opposite to each other; the power output end of the driving structure 43 is drivenly connected to the pushing part 42, and can drive the second inclined surface 421 to approach or move away from the first inclined surface 411.

[0080] Specifically, the second clamping part 41 is rotatably disposed within the first movable cavity 14 and is opposite to the first clamping part 51, for clamping the quick-release plate. The pushing part 42 is disposed in the first movable cavity 14, and through the cooperation between the first inclined surface 411 and the second inclined surface 421, it pushes the second clamping part 41 to rotate. The driving structure 43 provides power to drive the pushing part 42 to move, thereby causing the second clamping part 41 to rotate until it can abut against the quick-release plate.

[0081] The second clamping part 41 is rotatably disposed within the first movable cavity 14 via a rotating shaft 412, and can rotate axially around the rotating shaft 412 within the first movable cavity 14. The second clamping part 41 is provided with a first inclined surface 411, which cooperates with the second inclined surface 421 of the pushing part 42. That is, the first inclined surface 411 allows the second clamping part 41 to rotate when acted upon by the pushing part 42. The pushing part 42 is disposed within the first movable cavity 14, and is provided with a second inclined surface 421, which is opposite to the first inclined surface 411 of the second clamping part 41. Through the interaction between the two inclined surfaces, the pushing part 42 drives the second clamping part 41 to rotate. The pushing part 42 is drivenly connected to the power output end of the drive structure 43, and can receive the power released by the drive structure 43, thereby enabling the pushing part 42 to move along the direction of the second clamping part 41.

[0082] For example, when the second clamping part 41 is in its initial position, the first inclined surface 411 and the second inclined surface 421 are positioned opposite each other but not yet in contact, and the pushing part 42 is also in its initial position, with the second inclined surface 421 opposite to the first inclined surface 411 but not yet in contact. The driving structure 43 is in an inactive state, and the power output end does not apply force to the pushing part 42. When the quick-release plate is inserted between the first clamping part 51 and the second clamping part 41, the driving structure 43 is activated, causing its power output end to drive the second inclined surface 421 of the pushing part 42 to approach the first inclined surface 411 of the second clamping part 41. When the second inclined surface 421 abuts against the first inclined surface 411, the pushing part 42 pushes the second clamping part 41 to rotate through the interaction of the inclined surfaces. The second clamping part 41 rotates under the action of the pushing part 42 until it can abut against the quick-release plate. At this time, through the cooperation of the second clamping part 41 and the first clamping part 51, the quick-release plate is clamped together, thereby ensuring that the quick-release plate can be fixed.

[0083] It should be noted that when the second inclined surface 421 abuts against the first inclined surface 411, an interaction force is generated between the two inclined surfaces. Due to the design of the inclination angle of the inclined surfaces, this interaction force can be decomposed into two components, such as a vertical component and a horizontal component. The vertical component is perpendicular to the component of each inclined surface and is used to push the second clamping part 41 to rotate. The other horizontal component is parallel to the component of each inclined surface, so that the second inclined surface 421 of the pushing part 42 can slide along the first inclined surface 411, thereby achieving the function of further pushing the second clamping part 41.

[0084] according to Figure 11 As shown, it can be understood that the drive structure 43 includes a drive member 431 and a threaded shaft 432; the gimbal body 1 has a threaded opening 433 that communicates with the first movable cavity 14, and the threaded shaft 432 passes through the threaded opening 433. One end of the threaded shaft 432 is connected to the push part 42, and the other end of the threaded shaft 432 is connected to the drive member 431. When the drive member 431 drives the threaded shaft 432 to rotate, the threaded shaft 432 can move toward the second clamping part 41 due to the cooperation between the external thread of the threaded shaft 432 and the threaded opening 433. At this time, the threaded shaft 432 can synchronously drive the push part 42 to move along with it until the second inclined surface 421 of the push part 42 abuts against the second inclined surface 421, so as to push the second clamping part 41 to abut against the quick release plate.

[0085] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
