Description

Technical Field

[0001] The utility model belongs to the technical field of shooting auxiliary equipment, in particular to a quick-release plate. Background Art

[0002] In the field of photography, shooting auxiliary equipment such as shooting stabilizers, shooting pan heads, tripods, etc. are all connected to the shooting equipment through quick release mounts. For photographers, the relatively complicated quick release mount assembly process may cause them to miss some important photographic images, affecting the photography experience.

[0003] Chinese patent CN221323905U discloses a "quick-install mechanism" comprising a base, a movable block, a locking block, a quick-install seat, and a trigger assembly. When the trigger is in the released position, the quick-install seat can be pressed into a dovetail groove from the front of the base. When the trigger is in the locked position, the trigger pushes the locking block toward the movable block, allowing the locking block and movable block to cooperate and lock the quick-install seat in the dovetail groove. However, this device requires manual movement of the trigger to a fixed position for locking or unlocking, requiring considerable effort to pull the trigger, making it difficult to quickly install or remove the quick-install seat and consuming considerable time and effort. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the utility model provides a quick release plate, which can quickly assemble and unlock the shooting equipment and photographic accessories by pressing a button. The operation is simple, time-saving and labor-saving, and the installation is stable and not easy to fall off.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a quick-release plate, comprising:

[0006] a first adapter;

[0007] a second adapter, formed with an accommodating cavity, into which at least a portion of the first adapter can extend;

[0008] A limiting assembly includes a locking member and an unlocking member, wherein the unlocking member is movably connected to the second adapter member, and the locking member has at least a locking portion, and the locking portion extends into or tends to extend into the accommodating cavity;

[0009] External force is applied to drive the unlocking member to move relative to the second adapter member, which drives the locking member to rotate, so as to achieve locking or releasing of the first adapter member by the locking portion.

[0010] The utility model realizes the assembly and disassembly of the first adapter member through the cooperation of the limit component and the second adapter member. The unlocking member is pressed to trigger the locking part to loosen the first adapter member, so that the first adapter member and the second adapter member are quickly separated, and the unlocking process is quick and simple. During installation, it is only necessary to loosen the unlocking member, thereby driving the locking member to automatically reset, so that the first adapter member and the second adapter member can be quickly assembled. The installation is convenient and stable and not easy to fall, which effectively prevents the shooting equipment from falling and being damaged. The overall structure is simple and the operation saves time and effort.

[0011] Furthermore, the lock member is rotatably connected to the second adapter member and further comprises an actuating portion and a pivot point, with the actuating portion and locking portion located on either side of the pivot point. The unlocking member comprises an inclined surface, with the actuating portion abutting against the inclined surface. The inclined surface drives the actuating portion to slide along the inclined direction of the inclined surface, thereby driving the lock member to rotate, extend, or extend into the accommodating cavity, thereby releasing and locking the lock member relative to the first adapter member. The inclined surface and the actuating portion have a simple structure and are easy to manufacture.

[0012] Furthermore, the locking member and the elastic member abut against each other. When the unlocking member moves relative to the second adapter, the inclined surface drives the action portion to tilt upward, thereby driving the locking portion to rotate away from the first adapter, thereby releasing the locking portion from the first adapter. When the unlocking member moves in the opposite direction relative to the second adapter, the elastic member drives the action portion to return to its original position along with the inclined surface, causing the locking portion to tilt upward and extend into the accommodating cavity, thereby locking the locking portion to the first adapter. The elastic member recovers its deformation, thereby automatically driving the locking portion to tilt upward, facilitating the locking portion to reset and lock the first adapter in a timely manner, thereby preventing the locking portion from becoming stuck during reset and affecting the locking function of the quick-release plate. Furthermore, the elastic member has a variety of structures to meet different usage requirements.

[0013] Furthermore, the action portion is a columnar structure; there are two action portions, which are symmetrically arranged on both sides of the lock. The columnar structure of the action portion can reduce the friction between the sliding surface and the inclined surface, making it easier for the action portion to slide relative to the inclined surface. The two action portions are symmetrically arranged on both sides of the lock. In this case, the width of the locking portion is increased, thereby increasing the contact area between the locking portion and the first adapter, ensuring the locking effect of the locking portion on the first adapter, and the action portion can apply a force to the locking portion from both sides of the lock at the same time. Even when the width of the locking portion is increased, it is ensured that the locking portion can be tilted up smoothly, avoiding the locking portion from being unstable on the first adapter due to uneven force on both sides.

[0014] Furthermore, the position limiting assembly further includes a reset member that abuts against the unlocking member and the second adapter member, respectively, to drive the unlocking member to move back to its original position. After releasing the unlocking member, the reset member automatically pushes the unlocking member back to its original position, eliminating the need for the user to manually pull the unlocking member back to its original position. This simplifies the operation and saves time and effort during use.

[0015] Furthermore, the unlocking member includes an anti-slip key and a raised portion. The second adapter includes a mounting slot. The raised portion extends through the mounting slot into the second adapter and is slidably connected to the anti-slip key. The anti-slip key can slide relative to the raised portion until it abuts against the side wall of the second adapter. The anti-slip key locks the unlocking member, preventing the operator from accidentally touching the unlocking member during use, causing the first and second adapters to unlock, which could result in the camera device and the photographic accessory separating and falling, causing damage, thereby providing greater safety.

[0016] Furthermore, the locking portion is hook-shaped. The hook-shaped structure is convenient for clamping one end of the first adapter to fix the first adapter, and when the locking portion rotates out of the accommodating cavity, the hook-shaped structure can form a large retreat space, making it convenient to remove the first adapter from the second adapter.

[0017] Furthermore, a latching portion is provided on one side of the accommodating chamber opposite the stop assembly, with which a portion of the first adapter can engage. The inclined sidewall of the latching portion mates with the inclined engaging surface of the first adapter, facilitating the latching portion's locking of the first adapter, preventing the first adapter from escaping from the accommodating chamber and effectively protecting the camera from damage due to falling.

[0018] Furthermore, the first adapter has a threaded interface and the second adapter has a dovetail groove. The threaded interface can be used to install a camera, and the dovetail groove is used to install a tripod, a pan head and other photographic accessories. It can be used with a variety of photographic equipment and is highly practical.

[0019] The beneficial effects of the present invention are as follows: 1) The assembly and disassembly of the first adapter and the second adapter are achieved through the limit assembly. Pressing the anti-slip key triggers the locking part to loosen the first adapter, thereby achieving rapid separation of the first adapter and the second adapter, and the unlocking process is quick and simple. During installation, only the anti-slip key needs to be released, thereby driving the lock to automatically reset, thereby achieving rapid assembly of the first adapter and the second adapter, which is convenient to operate, saving time and effort. 2) The inclined surface drives the action part to slide relative to each other, thereby driving the lock to rotate, which has a simple structure and is easy to implement. 3) The setting of the anti-slip key can prevent the operator from accidentally touching the unlocking part during use, resulting in the unlocking of the first adapter and the second adapter, and has higher safety performance. 4) The clamping part and the locking part respectively lock the first adapter from both ends of the first adapter, which is firmly installed to prevent the first adapter from detaching from the accommodating cavity, effectively preventing the shooting equipment from falling and being damaged.

DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0038] like Figures 1-16 As shown, a quick release plate includes a first adapter 1, a second adapter 2 and a limit assembly 3. The second adapter 2 has a receiving cavity 21 and a square fixing seat 23. At least a portion of the first adapter 1 can extend into the receiving cavity 21. The limit assembly 3 includes a locking member 31 and an unlocking member 32. The unlocking member 32 is movably connected to the second adapter 2. Figure 5 Taking the illustrated orientation as an example, the unlocking member 32 is connected to the second adapter 2 so as to be movable horizontally left and right. The locking member 31 includes at least a locking portion 311, which can extend into or tend to extend into the accommodating cavity 21, for locking and releasing the first adapter 1. In this embodiment, the locking portion 311 is hook-shaped. This hook-like structure facilitates gripping one end of the first adapter 1 to secure it. Furthermore, when the locking portion 311 extends out of the accommodating cavity 21, the hook-like structure creates a large retractable space, facilitating removal of the first adapter 1 from the second adapter 2.

[0039] When an external force is applied to drive the unlocking member 32 to move relative to the second adapter 2, the unlocking member 32 can drive the locking member 31 to rotate, thereby achieving the locking or release of the locking portion 311 on the first adapter 1. Specifically, the movement between the unlocking member 32 and the second adapter 2 is a translation movement. Figure 5Taking the direction shown as an example, when the unlocking member 32 moves horizontally to the left, the locking portion 311 rotates clockwise, that is, it moves in the direction of extending or tending to extend out of the accommodating cavity 21, thereby unlocking and releasing the first adapter 1 in the accommodating cavity 21; when the unlocking member 32 moves horizontally to the right, the locking portion 311 rotates counterclockwise, that is, it moves in the direction of extending or tending to extend into the accommodating cavity 21, thereby locking the first adapter 1 in the accommodating cavity 21.

[0040] like Figure 2-Figure 4 As shown, the accommodating cavity 21 is a square depression formed on the upper surface of the second adapter 2, excluding the internal structure of the second adapter 2. The top of the accommodating cavity 21 is open, with side walls formed around it to accommodate the first adapter 1. This increases the contact area between the first adapter 1 and the accommodating cavity 21, facilitating a tight locking of the first adapter 1 within the accommodating cavity 21 and preventing it from slipping out. The accommodating cavity 21 has a side opening on the side where the stop assembly 3 is located, through which the locking portion 311 extends into or out of the accommodating cavity 21.

[0041] like Figure 5 、 Figure 6 As shown, the side of the accommodating cavity 21 opposite the stop assembly 3 is recessed inward to form a latching portion 211. A portion of the first adapter 1 extends into the latching portion 211 and engages therewith, and the sidewalls of the latching portion 211 are inclined sidewalls. In this embodiment, inclined latching surfaces 12 are formed on opposite sides of the first adapter 1. One side engages with the inclined sidewall of the latching portion 211, and the other side engages with the hook-shaped structure of the locking portion 311. As a result, the latching portion 211 and the locking portion 311 respectively lock the first adapter 1 from opposite sides of the first adapter 1, preventing the first adapter 1 from escaping from the accommodating cavity 21 and effectively preventing the camera from falling and being damaged. Of course, in other embodiments, the latching portion 211 can be provided on both sides of the accommodating cavity 21 adjacent to the stop assembly 3, thereby also achieving locking of the first adapter 1. This is not a limitation.

[0042] like Figure 7-Figure 9 As shown, the lock member 31 further comprises an operating portion 312 and a pivot point 313. The pivot point 313 is located on the square fixing seat 23 at the bottom of the second adapter member 2, enabling the lock member 31 to pivot relative to the second adapter member 2. The operating portion 312 and the locking portion 311 are located on either side of the pivot point 313. The operating principle of the operating portion 312, pivot point 313, and locking portion 311 is similar to that of a seesaw. The pivot point 313 serves as a relatively stationary fulcrum. When the operating portion 312 rises with the pivot point 313 as the fulcrum, the locking portion 311 descends. When the locking portion 311 rises with the pivot point 313 as the fulcrum, the operating portion 312 descends.

[0043] The cam 330 has two locking cams 331 on each side of the lock member 31 so that the lock member 31 can be locked without any problems.

[0044] The unlocking member 32 has an inclined surface 321, and the action portion 312 abuts against the inclined surface 321. The tilting of the action portion 312 is driven by the inclined surface 321. Specifically, Figure 6 As shown, the inclined surface 321 extends obliquely from left to right and from bottom to top. When the unlocking member 32 moves relative to the second adapter 2, the inclined surface 321 drives the action portion 312 to slide along the inclined direction of the inclined surface 321, thereby driving the locking portion 311 to rotate. In this embodiment, the action portion 312 is a columnar structure, which can reduce the friction between the action portion 312 and the inclined surface 321 and facilitate the sliding of the action portion 312 relative to the inclined surface 321. Of course, in other embodiments, the specific structure of the action portion 312 and the inclined surface 321 is not limited, as long as the locking member 31 can be driven to rotate when the unlocking member 32 is driven. Similarly, the number of inclined surfaces 321 is also two, which is the same as the number of action portions 312.

[0045] like Figure 7 As shown, the bottom of the lock member 31 is against the elastic member 33, and the elastic member 33 is used to drive the locking portion 311 to reset and lock. Specifically, when the unlocking member 32 moves relative to the second adapter 2, the inclined surface 321 drives the action portion 312 to tilt, thereby driving the locking portion 311 to rotate away from the first connecting member 1, so that the locking portion 311 can relax the first connecting member 1. At this time, the elastic member 33 is squeezed by the locking portion 311 and deformed; when the unlocking member 32 moves in the opposite direction relative to the second adapter 2, the elastic member 33 recovers its deformation, pushing the locking portion 311 to tilt and extend into the accommodating cavity 21, thereby driving the action portion 312 to slide and reset along the inclined surface 321, so that the locking portion 311 can lock the first adapter 1, and also avoid the locking portion 311 from getting stuck when resetting, affecting the locking function of the quick release plate. In this embodiment, the elastic member 33 is a spring. In other embodiments, the elastic member 33 can also be a torsion spring, such as Figure 13As shown, the elastic member 33 is connected between the two rotation fulcrums 313 , and one end of the elastic member 33 abuts against the locking portion 311 , so as to drive the locking portion 311 to tilt up and thereby lock the first adapter 1 .

[0046] like Figure 10 As shown, the limit assembly 3 further includes a reset member 34 and a groove 35. In this embodiment, the reset member 34 is a spring, and its two ends respectively abut against the unlocking member 32 and the second adapter 2 to automatically reset the unlocking member 32. Specifically, the unlocking member 32 and the second adapter 2 are combined to form a groove 35 for accommodating the reset member 34. Half of the end of the reset member 34 abuts against the unlocking member 32, and the other half abuts against the second adapter 2. When the unlocking member 32 is pressed, the unlocking member 32 moves relative to the second adapter 2, and the groove 35 on the unlocking member 32 is offset relative to the groove 35 on the second adapter 2, thereby driving one end of the reset member 34 to disengage from the counteraction of the second adapter 2, and the other end of the reset member 34 is deformed by the counteraction of the second adapter 2; when the unlocking member 32 is released, the reset member 34 recovers its deformation, pushing the unlocking member 32 to move in the opposite direction relative to the second adapter 2, thereby realizing automatic reset of the unlocking member 32, and the user does not need to manually pull the unlocking member 32 to reset it, which simplifies the operation steps and saves time and effort when in use.

[0047] Of course, the reset member 34 can also be arranged in other ways, such as Figure 11 、 Figure 12 As shown, the reset member 34 is a spring, and there are two of them, one located on one side of the unlocking member 32 near the inclined surface 321. One end of the reset member 34 abuts against the unlocking member 32, and the other end abuts against the second adapter 2, driving the unlocking member 32 to reset. This arrangement eliminates the need for grooves 35 in the unlocking member 32 and the second adapter 2, resulting in a simpler structure and easier processing. Of course, in other embodiments, the reset member 34 can be omitted, and the unlocking member 32 can be reset simply by manually pulling it, without limitation.

[0048] In order to prevent the operator from accidentally touching the unlocking member 32 during use, causing the first adapter 1 and the second adapter 2 to separate, as shown in FIG. Figure 4 、 Figure 13 、 Figure 14 As shown, the unlocking member 32 further includes an anti-slip key 322 and a raised portion 323. The back of the anti-slip key 322 has a slide groove 3221 with a trapezoidal cross-section. The raised portion 323 is located at one end of the unlocking member 32 near the anti-slip key 322, corresponding to the slide groove 3221. The raised portion 323 has a trapezoidal cross-section and is sized to match the slide groove 3221. The anti-slip key 322 can be slidably connected to the raised portion 323 from one end along the extension direction of the raised portion 323.

[0049] like Figure 4As shown, the second adapter 2 further includes a mounting slot 24 extending through the sidewall of the second adapter 2. The protrusion 323 extends through the mounting slot 24 and out of the interior of the second adapter 2, and is connected to the anti-disengagement key 322. In this embodiment, the opening of the mounting slot 24 is the same size as the anti-disengagement key 322, ensuring that the anti-disengagement key 322 can smoothly enter and exit the mounting slot 24, facilitating the user to apply force to the anti-disengagement key 322 to activate the unlocking member 32. Of course, in other embodiments, the anti-disengagement key 322 can be smaller than the mounting slot 24, and this is not a specific limitation.

[0050] Furthermore, the anti-stripping key 322 is slidably connected to the protrusion 323, and the anti-stripping key 322 can slide relative to the protrusion 323 until it abuts against the side wall of the second adapter 2. Figure 14 Taking the direction shown as an example, applying an external force to push the anti-dropout key 322 to the left relative to the protrusion 323, the anti-dropout key 322 abuts against the side wall of the second adapter 2. At this point, the anti-dropout key 322 is in a locked state, and the unlocking member 32 cannot be unlocked by pressing the external anti-dropout key 322. This prevents the user from accidentally pressing the unlocking member 32, causing the first adapter 1 and the second adapter 2 to unlock, thereby causing the photographic device and the photographic accessory to separate and fall, resulting in loss, and providing increased safety. Applying an external force to push the anti-dropout key 322 to the right relative to the protrusion 323 until the anti-dropout key 322 no longer abuts against the side wall of the second adapter 2, allowing the anti-dropout key 322 to smoothly enter and exit the mounting slot 24. At this point, the anti-dropout key 322 is in an unlocked state. Applying an external force to press the anti-dropout key 322 causes the unlocking member 32 to move perpendicular to the paper, thereby causing the lock member 31 to rotate, thereby locking or releasing the locking portion 311 from the first adapter 1.

[0051] like Figure 4 、 Figure 13 As shown, the back of the anti-slip key 322 is provided with a spherical groove 1 3222 and a spherical groove 2 3223, an arc channel 3224 is provided between the spherical groove 1 3222 and the spherical groove 2 3223, and the protrusion 323 is provided with a limiting ball 3231, which protrudes from the surface of the protrusion 323. When the anti-slip key 322 is in the unlocked state, the limiting ball 3231 is in the spherical groove 1 3222. When the anti-slip key 322 needs to be locked, an external force is applied to push the anti-slip key 322 to slide relative to the protrusion 323. At this time, the limiting ball 3232 slides from the spherical groove 1 3222 to the spherical groove 2 3223 through the arc channel 3224. When the anti-slip key 322 is restored to the unlocked state, an external force is applied to push the anti-slip key 322 in the opposite direction, and the limiting ball 3232 slides from the spherical groove 2 3223 to the spherical groove 1 3222 through the arc channel 3224.

[0052] The spherical groove and the limiting ball 3231 cooperate to limit the sliding position of the anti-slip key 322, so that the anti-slip key 322 can maintain its position after sliding; at the same time, it prevents the anti-slip key 322 from sliding off the protrusion 323 due to excessive sliding distance, thereby losing the locking effect of the anti-slip key 322 on the unlocking member 32. Of course, other anti-slip structures can be provided in other embodiments, and the specific details are not limited thereto.

[0053] like Figure 1 As shown, the first adapter 1 has a threaded interface 11 for installing a camera, etc., and the second adapter 2 has a dovetail groove 22 for installing photographic accessories such as a tripod and a pan head. Thus, through the cooperation of the first adapter 1 and the second adapter 2, the assembly connection of photographic equipment and photographic accessories is achieved. The side where the anti-slip key 322 is located is defined as the width direction of the second adapter 2, and the two adjacent sides of the anti-slip key 322 are defined as the length direction of the second adapter 2. In this embodiment, the dovetail groove 22 is provided in the length direction of the second adapter 2. Of course, in other embodiments, the dovetail groove 22 can be provided in both the length direction and the width direction of the second adapter 2, such as Figure 15 、 Figure 16 As shown, the lengths of the dovetail grooves 22 are different, so the second adapter 2 can be installed with different photographic accessories, which is highly practical; alternatively, the dovetail grooves 22 can be provided in the width direction of the second adapter 2 .

[0054] The working process of this utility model:

[0055] by Figure 7 When the first adapter 1 and the second adapter 2 need to be disassembled, the anti-slip key 322 is slid to a position where it coincides with the protrusion 323, and the anti-slip key 322 is in the unlocked state. The anti-slip key 322 is pressed, and the unlocking member 32 moves leftward relative to the second adapter 2 in the horizontal direction. The reset member 34 is deformed by the pressure of the second adapter 2, and the inclined surface 321 drives the action portion 312 to slide upward along the inclined surface 321, thereby driving the locking portion 311 to rotate away from the first adapter 1, so that the locking portion 311 is loosened from the first adapter 1, and the first adapter 1 assembled on the second adapter 2 can be easily disassembled, and the elastic member 33 is squeezed and deformed due to the rotation of the locking portion 311.

[0056] When it is necessary to fix and assemble the first adapter 1 and the second adapter 2, first press the anti-slip key 322, so that the locking portion 311 rotates and extends out of the accommodating cavity 21, and the first adapter 1 is placed in the accommodating cavity 21; release the anti-slip key 322, the reset member 34 restores its deformation and pushes the unlocking member 32 to move in the opposite direction relative to the second adapter 2, and the action portion 312 slides obliquely downward along the inclined surface 321 to the bottom of the inclined surface 321. At the same time, the elastic member 33 restores its deformation, pushing the locking portion 311 to tilt up and extend into the accommodating cavity 21, and engages with the first adapter 1 to achieve locking of the first adapter 1. By pressing a button, the first adapter 1 and the second adapter 2 can be quickly separated, and the unlocking process is convenient and quick. When the anti-detachment key 322 is released, the limit assembly 3 automatically rebounds, thereby realizing the rapid assembly of the first adapter 1 and the second adapter 2, which is convenient to operate, saves time and effort; in addition, the first adapter 1 is fixed by the clamping portion 211 and the locking portion 311 to prevent the first adapter 1 from falling out of the accommodating cavity 21, thereby effectively preventing the shooting equipment from falling and being damaged.

[0057] by Figure 14 Taking the direction shown as an example, after the first adapter 1 and the second adapter 2 are assembled, the anti-slip key 322 is slid from right to left, and the anti-slip key 322 is in a locked state. A part of the anti-slip key 322 is against the side wall of the second adapter 2, and the other part is connected to the protrusion 323 to lock the unlocking member 32, so as to prevent the user from accidentally touching the unlocking member 32, causing the first adapter 1 and the second adapter 2 to be unlocked and separated.

[0058] The above specific implementation methods are used to illustrate the present invention rather than to limit the present invention. Any modifications and changes made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.

A quick release plate, characterized in that: include: A first adapter (1); A second adapter (2) is formed with a receiving cavity (21), and at least a portion of the first adapter (1) can extend into the receiving cavity (21); A limiting assembly (3) includes a locking member (31) and an unlocking member (32), wherein the unlocking member (32) is movably connected to the second adapter (2), and the locking member (31) has at least a locking portion (311), and the locking portion (311) extends into or tends to extend into the accommodating cavity (21); External force is applied to drive the unlocking member (32) to move relative to the second adapter (2), which drives the locking member (31) to rotate, thereby achieving locking or releasing of the first adapter (1) by the locking portion (311).

2. The quick release plate according to claim 1, characterized in that: The locking member (31) is rotatably connected to the second adapter (2), and further comprises an action portion (312) and a rotation fulcrum (313). The action portion (312) and the locking portion (311) are located on both sides of the rotation fulcrum (313). The unlocking member (32) comprises an inclined surface (321), and the action portion (312) abuts against the inclined surface (321).

3. The quick release plate according to claim 2, characterized in that: The locking member (31) and the elastic member (33) are in contact with each other. When the unlocking member (32) moves relative to the second adapter (2), the inclined surface (321) drives the action portion (312) to tilt up, thereby driving the locking portion (311) to rotate away from the first adapter (1), so as to achieve the release of the locking portion (311) from the first adapter (1). When the unlocking member (32) moves in the opposite direction relative to the second adapter (2), the elastic member (33) drives the action portion (312) to return to its original position along with the inclined surface (321), and the locking portion (311) tilts up and extends into the accommodating cavity (21), so as to achieve the locking portion (311) locking the first adapter (1).

4. The quick release plate according to claim 2, wherein: The action portion (312) is a columnar structure; there are two action portions (312), which are symmetrically arranged on both sides of the locking element (31).

5. The quick release plate according to claim 1, characterized in that: The limiting assembly (3) further includes a reset member (34), which respectively abuts against the unlocking member (32) and the second adapter member (2) to drive the unlocking member (32) to move and reset.

6. The quick release plate according to claim 1, characterized in that: The unlocking member (32) includes an anti-slip key (322) and a protrusion (323); the second adapter (2) includes a mounting slot (24); the protrusion (323) extends through the mounting slot (24) and out of the second adapter (2) and is slidably connected to the anti-slip key (322); the anti-slip key (322) can slide relative to the protrusion (323) until it abuts against the side wall of the second adapter (2).

7. The quick release plate according to claim 1, characterized in that: The locking portion (311) is hook-shaped.

8. The quick release plate according to claim 1, characterized in that: A clamping portion (211) is provided on a side of the accommodating cavity (21) opposite to the limiting assembly (3), and a portion of the first adapter (1) can be clamped and engaged with the clamping portion (211).

9. The quick release plate according to claim 1, characterized in that: The first adapter (1) has a threaded interface (11), and the second adapter (2) has a dovetail groove (22).
