Description

Technical Field

[0001] This utility model relates to the field of photographic auxiliary accessories technology, and in particular to a cold shoe quick-release assembly and a camera cage. Background Technology

[0002] Quick-release mounts are common support accessories for camcorders and cameras, used for quickly mounting and securing photography and videography accessories (phones, fill lights, microphones, etc.). To provide a better shooting experience, commercially available quick-release mounts not only allow for quick installation and removal of various equipment accessories but also incorporate anti-detachment limiting structures to improve stability after installation. However, with traditional cold shoe mounts, there is a risk that the cold shoe may detach from the cold shoe groove after assembly, and the stability between the two is not strong enough. Utility Model Content

[0003] The present invention provides a cold shoe quick-release assembly and a camera cage to solve the technical problem that, after the traditional cold shoe toe and cold shoe base are assembled, the cold shoe toe may detach from the cold shoe groove, and the stability between the two is not strong enough.

[0004] First aspect This utility model discloses a quick-release assembly for a cold boot, comprising: The cold shoe mount includes a first fixed base and plug-in seats disposed on opposite sides of the first fixed base. The two plug-in seats are connected at intervals to the same side of the first fixed base to form a cold shoe groove extending along a first direction. The cold shoe toe includes a second fixing seat and a pair of plug-in blocks adapted to the cold shoe groove. The two plug-in blocks are spaced apart and connected to the same side of the second fixing seat and extend in opposite directions. One of the plug-in seat and the corresponding plug-in block is provided with a slot, and the other is provided with a locking block. When the plug-in block is installed in the cold shoe groove, the locking block is aligned and engaged in the slot to prevent the cold shoe toe from disengaging from the cold shoe seat. An unlocking component is movably mounted on the second fixed base. The unlocking component includes a pair of driving blocks and a pair of elastic members. The two driving blocks are respectively fixedly connected to the two plug-in blocks, and the elastic members are disposed between the two plug-in blocks. The two plug-in blocks can be driven away from each other under the force of the elastic members to be installed in the cold shoe groove. The locking block is aligned and engaged in the slot. When the driving blocks are pressed, the two plug-in blocks can be brought closer together to disengage the locking block from the slot. At this time, the plug-in block can slide along the first direction and disengage from the cold shoe groove.

[0005] In one embodiment, the connector has a first guide surface at at least one end edge along the first direction, the first guide surface extending inclined in the first direction toward the inside of the cold shoe groove; or, the connector block has a first guide surface at at least one end edge along the first direction, the first guide surface extending inclined in the first direction toward the inside of the cold shoe groove. When assembling the cold shoe mount and the cold shoe toe, the locking block moves along the first guide surface. The locking block is squeezed by the first guide surface, causing the two plug blocks to move closer to each other. The elastic element accumulates elastic force until the locking block moves to the end of the first guide surface. The elastic element drives the locking block to instantly lock into the slot.

[0006] In one embodiment, the connector has an L-shaped structure and includes a first vertical section and a first horizontal section. The first vertical section is connected to the first fixed seat at an angle, and the first horizontal section is connected to the side of the first vertical section away from the first fixed seat at an angle. The first horizontal section is spaced apart from the first fixed seat, and the first horizontal section has a first abutting slope on its inner sidewall facing the first fixed seat. The first abutting slope is inclined in the depth direction of the cold shoe groove. The plug block has an L-shaped structure and includes a second vertical section and a second horizontal section. The second vertical section is connected to the second fixed seat at an angle, and the second horizontal section is connected to the side of the second vertical section away from the second fixed seat at an angle. The second horizontal section is spaced apart from the second fixed seat, and the second horizontal section has a second abutting slope on its inner sidewall facing the second fixed seat. The second abutting slope is inclined in the depth direction of the cold shoe groove. Wherein, the first guide surface is formed on the end face of the first horizontal segment and is connected at an angle to the second abutting slope, or the first guide surface is formed on the end face of the second horizontal segment and is connected at an angle to the first abutting slope; when the plug block is installed in the cold shoe groove, the elastic force released by the elastic element drives the second abutting slope to abut against the first abutting slope.

[0007] In one embodiment, at least one end of the second abutting ramp is connected to a second guide surface along the first direction, and the vertical straight distance between the second guide surface and the second fixed seat gradually decreases along the sliding installation direction. When the plug is installed in the cold shoe groove, the intersection line of the second guide surface and the second abutting ramp abuts against the first abutting ramp.

[0008] In one embodiment, at least one end of the first abutting ramp is connected to a second guide surface along the first direction, and the vertical straight-line distance between the second guide surface and the first fixing seat gradually decreases along the sliding installation direction. When the plug is installed in the cold shoe groove, the intersection line of the second guide surface and the first abutting ramp abuts against the second abutting ramp.

[0009] In one embodiment, the cold shoe mount is provided with a first threaded interface, which is exposed for external threading when the plug block is installed in the cold shoe groove; and / or, the cold shoe head is provided with a second threaded interface, which is exposed for external threading when the plug block is installed in the cold shoe groove.

[0010] In one embodiment, one of the second fixing seat and the cold shoe seat is provided with a slide rail, and the other is provided with a protrusion. The slide rail passes through the opposite two sides of the cold shoe seat along the first direction. When the plug block is slidably installed in the cold shoe groove, the protrusion is limited to the slide rail and moves from one end of the slide rail to the other end.

[0011] In one embodiment, the second fixed base has two parallel linkage rods built in, the axis of the linkage rods being parallel to the direction of the two plug blocks facing each other; each linkage rod has a connecting end and a free end opposite to each other along its axis, and for the same linkage rod, the connecting end is fixedly connected to one of the plug blocks, and the free end is movably inserted through the other plug block; The elastic element is a telescopic spring and is sleeved on the outside of the linkage rod. The driving block is exposed on the second fixed seat. Pressing the driving block can drive the linkage rod to slide relative to the plug block along its axial direction. The two plug blocks are brought closer to each other, and the spring is compressed to accumulate elastic force.

[0012] In one embodiment, the second fixed base has two sliding grooves on opposite side walls along the axial direction of the linkage rod, the sliding grooves allowing the drive block to pass through and move, and the plug-in block is located between the two drive blocks; or, the same side wall of the second fixed base has a sliding groove extending along the axial direction of the linkage rod, the sliding groove allowing the two drive blocks to slide through; pressing the two drive blocks closer or further apart can cause the two plug-in blocks to move closer or further apart synchronously.

[0013] Second aspect This application provides a camera cage, comprising: A camera frame having a mounting cavity for securely accommodating a camera; and As described in any of the preceding embodiments, the first mounting bracket is connected to the camera frame; or the second mounting bracket is connected to the camera frame.

[0014] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects: This utility model provides a cold shoe quick-release assembly and a camera cage. The cold shoe quick-release assembly is connected to the camera frame and serves as a photographic auxiliary accessory for camera shooting. The cold shoe quick-release assembly includes a cold shoe base, a cold shoe toe, and an unlocking component. The insertion base of the cold shoe base and the insertion block of the cold shoe toe engage in a sliding quick-release mechanism. The insertion base and the insertion block achieve the cold shoe toe anti-detachment function through the alignment and engagement of locking blocks and slots. Moreover, the double-sided limiting mechanism (two sets of locking blocks and slots) also restricts the left and right movement of the insertion block along the direction perpendicular to the sliding installation. Therefore, the locking blocks and slots not only prevent the cold shoe toe from detaching but also provide a four-way limiting function, restricting the cold shoe toe from moving forward, backward, left, and right within the cold shoe slot and from rotating circumferentially, greatly improving the assembly stability of the entire cold shoe quick-release assembly.

[0015] On the other hand, the unlocking mechanism includes a pair of opposing drive blocks and an elastic element. The two drive blocks are respectively fixed to the two plug-in blocks. Pressing the drive blocks controls the relative proximity or distance between the two plug-in blocks. The force provided by the elastic element can drive the two plug-in blocks away from each other to stably assemble them in the cold shoe groove of the cold shoe mount. At the same time, the locking block engages in the slot, greatly enhancing the assembly stability of the entire cold shoe quick-release assembly. Pressing the two drive blocks will cause the two plug-in blocks to move closer together, so that the locking block disengages from the slot, and the plug-in block can slide away from the cold shoe groove to separate the cold shoe toe from the cold shoe mount.

[0016] In summary, compared with traditional quick-release components, the cold shoe quick-release assembly provided in this application not only has an anti-slip function, but also has high assembly stability, simple unlocking operation, and strong practical function. Attached Figure Description

[0020] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Reference Figure 1-4 This application provides a stable and compact cold shoe quick-release assembly 10, including a cold shoe base 100, a cold shoe toe 200, and an unlocking member 300. The cold shoe base 100 and the cold shoe toe 200 slide and quick-release, and the unlocking member 300 is movably disposed on the cold shoe toe 200 for locking or unlocking the cold shoe quick-release assembly 10. Specifically, the cold shoe base 100 includes a first fixing base 110 and plug-in seats 120 disposed on opposite sides of the first fixing base 110. The two plug-in seats 120 are spaced apart and connected to the same side of the first fixing base 110 to form a cold shoe groove 101 extending along a first direction (i.e., the sliding installation direction). The cold shoe toe 200 includes a second fixing base 210 and a pair of plug-in blocks 220 adapted to the cold shoe groove 101. The two plug-in blocks 220 are spaced apart and connected to the same side of the second fixing base 210 and extend in opposite directions. Figure 2-4 In the middle, the plug-in base 120 and the corresponding plug-in block 220 are provided with a slot 130 and a block 230. When the plug-in block 220 is installed in the cold shoe groove 101, the block 230 is aligned and engaged in the slot 130, which restricts the movement of the plug-in block 220 in the cold shoe groove 101 along the sliding installation direction, so as to prevent the cold shoe head 200 from sliding off the cold shoe base 100.

[0024] Combination Figure 5 and 6The unlocking component 300 includes a pair of driving blocks 310 and a pair of elastic members 320. The two driving blocks 310 are fixedly connected to the two plug-in blocks 220, and the two elastic members 320 are disposed between the two plug-in blocks 220. The two plug-in blocks 220 can be driven away from each other by the elastic members 320 to be installed in the cold shoe groove 101, and the locking block 230 is engaged in the slot 130. Pressing the driving blocks 310 causes the two plug-in blocks 220 to move closer together so that the locking block 230 disengages from the slot 130. At this time, the plug-in block 220 can slide along the first direction and disengage from the cold shoe groove 101.

[0025] Preferably, in one embodiment, in conjunction with reference to Figure 2-4 The connector 120 has a first guide surface 123 at at least one end edge along a first direction. The first guide surface 123 extends inclined in the first direction toward the inner side of the cold shoe groove 101. A slot 130 is provided at the end of the first guide surface 123 (on the connector 120). A locking block 230 protrudes from the inner sidewall of the connector block 220 opposite to the first guide surface 123 (on the connector block 220). When assembling the cold shoe seat 100 and the cold shoe toe 200, the locking block 230 is pressed by the first guide surface 123, causing the two connector blocks 220 to move closer together. The elastic member 320 accumulates elastic force until the locking block 230 moves to the end of the first guide surface 123. The elastic member 320 drives the locking block 230 to instantly lock into the slot 130 to assemble the cold shoe quick-release assembly 10.

[0026] Here, the same assembly effect can be achieved by swapping the positions of the slots 130 and 130. Specifically, in another embodiment, the plug block has a first guide surface 123 at at least one end edge along the first direction. The first guide surface 123 extends inclined in the first direction toward the inside of the cold shoe groove 101. The slot 130 is located at the end of the first guide surface 123 (on the plug block 220). The locking block 230 protrudes from the inner sidewall of the plug seat 120 opposite to the first guide surface 123 (on the plug seat 120). When assembling the cold shoe seat 100 and the cold shoe toe 200, the locking block 230 is pressed by the first guide surface 123, causing the two plug blocks 220 to move closer together. The elastic member 320 accumulates elastic force until the locking block 230 moves to the end of the first guide surface 123. The elastic member 320 drives the locking block 230 to instantly lock into the slot 130 to assemble the cold shoe quick-release assembly 10.

[0027] It should be understood that the first guide surface 123 serves to guide the sliding installation along the first direction, allowing the elastic element 320 to automatically accumulate elastic force during the assembly process of the two plug blocks 220. This elastic force provides a restoring force for the locking block 230 to automatically engage with the slot 130, thereby improving the assembly convenience of the entire cold shoe quick-release assembly 10. Optionally, refer to... Figure 4In one embodiment, there are two first guide surfaces 123, which can be disposed on opposite sides of the slot 130, enabling the plug-in blocks 220 to be plugged in both directions, thereby further improving the assembly convenience of the cold shoe quick-release assembly 10. Of course, in other embodiments, there can be only one first guide surface 123. It should be noted that in other embodiments, the first guide surface 123 is not provided. When assembling the cold shoe seat 100 and the cold shoe toe 200, the user can first use external force to press the drive block 310 to bring the two plug-in blocks 220 closer together to a certain distance. The elastic element 320 accumulates elastic force. When the slot 130 and the plug 230 are aligned, the drive block 310 can be released, and the plug 230 can also be engaged in the slot 130. Therefore, without considering the ease of assembly, the provision of the first guide surface 123 is not limited in this application.

[0028] Preferably, refer to Figure 7 In one embodiment, the plug-in base 120 has an L-shaped structure and includes a first vertical section 121 and a first horizontal section 122. The first vertical section 121 is connected to the first fixed base 110 at an angle, and the first horizontal section 122 is connected to the side of the first vertical section 121 away from the first fixed base 110 at an angle. The first horizontal section 122 is spaced apart from the first fixed base 110. The first horizontal section 122 is provided with a first abutting slope 124 facing the inner wall of the first fixed base 110. The first abutting slope 124 is inclined in the depth direction of the cold shoe groove 101. Here, the depth direction refers to the depth direction of the cold shoe groove 101 recessed in the first fixed base 110 and is perpendicular to the first direction. The plug-in block 220 has an L-shaped structure and includes a second vertical section 221 and a second horizontal section 222. The second vertical section 221 is connected to the second fixing base 210 at an angle, and the second horizontal section 222 is connected to the side of the second vertical section 221 away from the second fixing base 210 at an angle. The second horizontal section 222 is spaced apart from the second fixing base 210. The second horizontal section 222 has a second abutting slope 224 facing the inner wall of the second fixing base 210. The second abutting slope 224 is inclined in the depth direction of the cold shoe groove 101. Figure 2When the first guide surface 123 is disposed on the plug-in seat 120, the first guide surface 123 is formed on the end face of the first horizontal segment 122 and is connected at an angle to the first abutting inclined surface 124; similarly, when the first guide surface 123 is disposed on the plug-in block 220, the first guide surface 123 is formed on the end face of the second horizontal segment 222 and is connected at an angle to the second abutting inclined surface 224. When the plug-in block 220 is installed in the cold shoe groove 101, the elastic force released by the elastic member 320 drives the second abutting inclined surface 224 to abut against the first abutting inclined surface 124. The two abutting inclined surfaces (the first abutting inclined surface 124 and the second abutting inclined surface 224) abut against each other from the left and right to prevent the corresponding two horizontal segments (the first horizontal segment 122 and the second horizontal segment 222) from moving relative to each other in a direction perpendicular to the first direction, thereby improving the assembly stability of the entire cold shoe quick-release assembly 10. It should be noted that, without considering assembly stability, the presence or absence of the first clamping slope 124 and the second clamping slope 224 is not limited in this application.

[0029] Preferably, in conjunction with reference Figure 4 and Figure 8 In one embodiment, at least one end of the second abutting slope 224 is connected to the second guide surface 223 along the first direction. Along the sliding installation direction, the vertical straight distance between the second guide surface 223 and the second fixed seat 210 gradually decreases. When the plug block 220 is installed in the cold shoe groove 101, the intersection line of the second guide surface 223 and the second abutting slope 224 abuts against the first abutting slope 124. Similarly, the second guide surface 223 connected to the first abutting slope 124 can also restrict the continued sliding of the plug block 220. Specifically, in another embodiment, at least one end of the first abutting slope 124 is connected to the second guide surface 223 (not shown in the figure) along the first direction. Along the sliding installation direction, the vertical straight distance between the second guide surface 223 and the first fixed seat 110 gradually decreases. When the plug block 220 is installed in the cold shoe groove 101, the intersection line of the second guide surface 223 and the first abutting slope 124 abuts against the second abutting slope 224.

[0030] It should be understood that the second guide surface 223 is used to guide the insertion block 220 to slide and assemble within the cold shoe groove 101. When the insertion block 220 is just assembled, the two clamping inclined surfaces abut against each other to limit the relative movement of the two horizontal sections along the sliding installation direction, thereby preventing the insertion block 220 from continuing to slide and improving the assembly stability of the entire cold shoe quick-release assembly 10. Optionally, refer to... Figure 4The second guide surface 223 is two in number and connected to the opposite ends of the second abutting inclined surface 224, enabling the plug-in block 220 to be plugged in both directions, thereby further improving the assembly convenience of the cold shoe quick-release assembly 10. Of course, in other embodiments, there may be only one second guide surface 223. It should be noted that, without considering the ease of assembly, the presence or absence of the second guide surface 223 is not limited in this application. Optionally, refer to Figure 2 In one embodiment, the cold shoe mount 100 is provided with a first threaded interface 140. When the plug-in block 220 is installed in the cold shoe groove 101, the first threaded interface 140 is exposed for external threaded connection. And / or, the cold shoe toe 200 is provided with a second threaded interface 240. When the plug-in block 220 is installed in the cold shoe groove 101, the second threaded interface 240 is exposed for external threaded connection. Here, both threaded interfaces are used for connecting external shooting equipment, auxiliary equipment, or support equipment. The two threaded interfaces are threaded holes or threaded heads to achieve external threaded connection. It should be understood that in other embodiments, the cold shoe mount 100 or the cold shoe toe 200 may be provided with other mounting interfaces for external connection, such as locking shafts, buckles, magnetic suction, clamping blocks, etc. Therefore, in this application, the presence or absence of the first threaded interface 140 or the second threaded interface 240 is not limited.

[0031] Preferably, in conjunction with reference Figure 2 and Figure 5 In one embodiment, one of the second fixing seat 210 and the cold shoe seat 100 is provided with a slide rail 150 and the other is provided with a protrusion 250. The slide rail 150 passes through the opposite two side edges of the cold shoe seat 100 along a first direction and is parallel to the cold shoe groove 101. When the plug block 220 is slidably installed in the cold shoe groove 101, the protrusion 250 is limited to the slide rail 150 and moves from one end of the slide rail 150 to the other end, so as to further limit the left and right offset of the plug block 220 in the cold shoe groove 101, thereby improving the assembly stability of the entire cold shoe quick-release assembly 10. Figure 2 As illustrated, there are two slide rails 150 located on the upper surfaces of the two connectors 120, and the protrusions 250 are strip-shaped and located on opposite sides of the second fixing base 210, adapting to and sliding and limiting the slide rails 150. It should be noted that, provided that the assembly of the cold shoe quick-release assembly 10 is sufficiently stable, the presence or absence of slide rails 150 and protrusions 250 is not limited in this application.

[0032] Optionally, in conjunction with reference Figure 5 and Figure 6In one embodiment, two parallel linkage rods 330 are provided inside the second fixed base 210, with the axial direction of the linkage rods 330 parallel to the direction in which the two plug blocks 220 face each other. Each linkage rod 330 has a connecting end 331 and a free end 332 that are opposite each other along its axial direction. For the same linkage rod 330, the connecting end 331 is fixedly connected to one of the plug blocks 220, and the free end 332 is movably inserted through the other plug block 220. The linkage rod 330 is part of the unlocking member 300. The elastic member 320 is a telescopic spring 321 and is sleeved on the outside of the linkage rod 330. The driving block 310 is exposed outside the second fixed base 210 and is fixedly connected to the plug block 220. Pressing the driving block 310 can drive the linkage rod 330 to slide relative to the plug block 220 along its axial direction. When the two plug blocks 220 are relatively close, the spring 321 is compressed and accumulates elastic force. The two connecting ends 331 here can be fixed to the same plug-in block 220, or they can be fixed to two different plug-in blocks 220 respectively. The linkage rod 330 not only provides a fixing member for the elastic element 320, but also provides a sliding track for the two plug-in blocks 220, improving the stability of the relative sliding of the two plug-in blocks 220 and keeping them on the same straight line or the same plane. It should be understood that in other embodiments, a sliding groove can also be directly provided in the second fixing seat 210 to provide a sliding track for the plug-in block 220, and it can also accommodate the elastic element 320. Therefore, in this application, the presence or absence of the linkage rod 330 is not limited, and the elastic element 320 can also be made of elastic rubber or other structures.

[0033] Preferably, refer to Figure 5 In one embodiment, the second fixed base 210 has two sliding grooves 211 on its opposite side walls along the axial direction of the linkage rod 330. The sliding grooves 211 allow the drive blocks 310 to pass through and move, and the plug-in block 220 is located between the two drive blocks 310. Alternatively, the same side wall of the second fixed base 210 has one sliding groove 211 (not shown) extending along the axial direction of the linkage rod 330. The sliding groove 211 allows the two drive blocks 310 to slide through. Pressing the two drive blocks 310 closer or further apart causes the two plug-in blocks 220 to move closer or further apart synchronously. It should be noted that each drive block 310 is fixedly connected to the corresponding plug-in block 220, so as long as the two drive blocks 310 extend out of the second fixed base 210 and can move relative to each other, the relative movement of the two plug-in blocks 220 can be controlled. Optionally, the drive block 310 can extend from the side wall of the second fixed seat 210 or from the upper surface of the second fixed seat 210. The drive block 310 and the second threaded interface 240 need to be located on different outer wall surfaces of the second fixed seat 210 to provide external installation space for the cold shoe head 200.

[0034] Secondly, refer to Figure 9This application provides a camera cage 1, including a cold shoe quick-release assembly 10 and a camera frame 20. The cold shoe quick-release assembly 10 is used to install shooting auxiliary accessories, and the camera frame 20 has a mounting cavity 21 for fixing and accommodating a camera (shooting equipment). A first fixing seat 110 is connected to the camera frame 20, or a second fixing seat 210 is connected to the camera frame 20.

[0035] This application provides a cold shoe quick-release assembly 10 and a camera cage 1. The cold shoe quick-release assembly 10 is connected to the camera frame 20 and is used to equip the camera with photographic auxiliary accessories. The cold shoe quick-release assembly 10 includes a cold shoe base 100, a cold shoe toe 200, and an unlocking component 300. The insertion base 120 of the cold shoe base 100 and the insertion block 220 of the cold shoe toe 200 cooperate to slide and quickly release the cold shoe. The insertion base 120 and the insertion block 220 achieve the anti-detachment function of the cold shoe toe 200 through the alignment and engagement of the locking block 230 and the locking slot 130. Moreover, the double-sided limiting mechanism (two sets of locking blocks 230 and locking slots 130) can also limit the left and right movement of the plug-in block 220 along the direction perpendicular to the sliding installation direction. Therefore, the locking blocks 230 and locking slots 130 not only play the role of preventing the cold shoe toe 200 from falling off, but also play the role of limiting the cold shoe toe 200 in four directions, restricting the cold shoe toe 200 from moving forward, backward, left and right and rotating circumferentially in the cold shoe slot 101, which greatly improves the assembly stability of the entire cold shoe quick-release assembly 10.

[0036] On the other hand, the unlocking component 300 includes a pair of opposing drive blocks 310 and an elastic element 320. The two drive blocks 310 are respectively fixed to the two plug-in blocks 220. Pressing the drive blocks 310 controls the relative proximity or distance between the two plug-in blocks 220. The force provided by the elastic element 320 can drive the two plug-in blocks 220 to move away from each other to stably assemble them in the cold shoe groove 101 of the cold shoe holder 100. At the same time, the locking block 230 engages in the locking groove 130, greatly enhancing the assembly stability of the entire cold shoe quick-release assembly 10. Pressing the two drive blocks 310 can drive the two plug-in blocks 220 to move closer together, so that the locking block 230 disengages from the locking groove 130. The plug-in blocks 220 can slide away from the cold shoe groove 101 to separate the cold shoe toe 200 from the cold shoe holder 100.

[0037] In summary, the cold shoe quick-release assembly 10 provided in this application not only has an anti-slip function compared to traditional quick-release assemblies, but also has high assembly stability, simple unlocking operation, and strong practical function.
