[0061] Figure 1 Schematic three-dimensional installation diagram of the bracket assembly 2 according to an embodiment of the present application. The bracket assembly 2 includes a bracket body 21 and a quick-installation assembly 22, and the quick-installation assembly 22 is detachably connected to the camera 3 and the bracket body 21. Figure 2 For Figure 1 Partial schematic diagram of the bracket assembly 2 of the illustrated embodiment including the quick-installation assembly 22, Figure 3 For Figure 2 Partial schematic diagram of another angle of the bracket assembly 2 shown, Figure 4 For Figure 1Schematic perspective view of the quick - mounting assembly 22 of the bracket assembly 2 of the illustrated embodiment. Please refer to Figures 1-4 , wherein the quick - mounting assembly 22 includes an upper plate 221 connected to the camera 3 and a lower plate 222 connected to the upper plate 221. The upper plate 221 includes an upper - plate main body 225, a hinged portion 223 extending downward from the upper - plate main body 225, and a buckle 224 extending downward from the upper - plate main body 225. The hinged portion 223 and the buckle 224 are spaced apart in the circumferential direction of the upper plate 221. The lower plate 222 is hinged to the hinged portion 223 and detachably clamped to the buckle 224. The quick - mounting assembly 22 is used for the quick disconnection and connection of the camera 3 and the bracket assembly 2. In some embodiments, one side of the lower plate 222 is hinged to the hinged portion 223 of the upper plate 221, so that the upper plate 221 and the lower plate 222 of the quick - mounting assembly 22 are always connected, which is easy to carry and not easy to lose. The quick - mounting assembly 22 includes a locked state and an unlocked state. In the locked state, the upper plate 221 is located above the lower plate 222, the lower plate 222 and the buckle 224 are clamped, and the upper plate 221 and the lower plate 222 clamp the bracket body 21. In the horizontal direction, the bracket body 21 passes through between the hinged portion 223 and the buckle 224. When the quick - mounting assembly 22 is in the unlocked state, the lower plate 222 is separated from the buckle 224, and the lower plate 222 can rotate downward around the hinged portion 223 to disengage the bracket body 21 from between the upper plate 221 and the lower plate 222.

[0062] For the bracket assembly 2 provided in the present application, by providing a quick - mounting assembly 22 between the bracket body 21 and the camera 3, the upper plate 221 and the lower plate 222 of the quick - mounting assembly 22 are hinged and can be fixed to the bracket body 21 through the buckle 224. In the locked state, the upper plate 221 and the lower plate 222 clamp the bracket body 21, and the load - bearing capacity is strong. In this way, the quick disassembly and assembly of the camera 3 and the bracket assembly 2 of the present application are realized. In order to ensure more reliable installation of the camera 3, the clamping strength of the buckle 224 can be appropriately increased.

[0063] For the bracket assembly 2 of the present application, by adopting the quick - mounting assembly 22, screw - free installation can be realized during the use by customers, which can greatly improve the overall installation and deployment efficiency.

[0064] In some embodiments, a camera connection portion 226 is provided on the upper surface of the upper plate 221. The camera connection portion 226 is fixedly connected or rotatably connected to the camera 3. In some embodiments, the camera connection portion 226 may include a camera fixing post, which is matched with a camera fixing hole on the outer shell of the camera 3 for fixation. In some embodiments, the camera connection portion 226 further includes a camera positioning post, which is matched with a camera positioning hole on the outer shell of the camera 3, so that the shooting angle of the camera 3 is fixed. In other embodiments, the camera connection portion 226 further includes an angle - adjustment assembly (not shown), so that the shooting angle of the camera 3 can be adjusted.

[0065] In the illustrated embodiment, a camera connection portion 226 is provided on the upper surface of the upper plate 221. The camera connection portion 226 is connected to the camera 3. The camera connection portion 226 is located in the middle of the upper plate body 225, and the central axis of the camera connection portion 226 coincides with the central axis of the fixing post 228. Thus, the pressure received by the quick-attachment assembly 22 and the supporting force given by the bracket body 21 to the quick-attachment assembly 22 are on the same straight line, avoiding fatigue fracture of the quick-attachment assembly 22 due to continuous shear force. Further, the connection position on the camera 3 with the camera connection portion 226 can be set directly below the center of gravity of the camera 3. Thus, the stability and safety of the bracket assembly 2 of the present application are higher.

[0066] In some embodiments, the quick-attachment assembly 22 is detachably connected to different positions of the bracket body 21. In other embodiments, the quick-attachment assembly 22 is slidably disposed on the bracket body 21 along the length direction of the bracket body 21. There is a small gap between the quick-attachment assembly 22 and the bracket body 21 in the locked state or the bracket body 21 is provided with a slide rail. The surface of the upper plate 221 or the lower plate 222 of the quick-attachment assembly 22 in contact with the bracket body 21 is provided with a mechanism that can cooperate with the slide rail, so that the camera 3 can slide on the bracket body 21, and thus the installation position of the camera 3 can be adjusted.

[0067] Please continue to refer to Figures 2-3 , in the illustrated embodiment, the quick-attachment assembly 22 includes a fixing member 227. A fixing post 228 extends downward from the lower surface of the upper plate 221. The bracket body 21 includes a plurality of fixing holes 229. Thus, the quick-attachment assembly 22 is relatively fixed on the bracket body 21. In the illustrated embodiment, a positioning post 230 extends downward from the lower surface of the upper plate 221. The bracket body 21 includes a plurality of positioning holes 231. When the quick-attachment assembly 22 is fixed to the bracket body 21, the positioning post 230 is inserted into the positioning hole 231, and the fixing post 228 is inserted into the fixing hole 229. The fixing member 227 fixedly connects the lower plate 222 and the fixing post 228. Thus, the quick-attachment assembly 22 is fixed at an angle relative to the bracket body 21, ensuring that the camera 3 can directly complete equipment alignment after being installed through the quick-attachment assembly 22, eliminating the angle adjustment step. In the illustrated embodiment, each fixing hole 229 corresponds to a positioning hole 231. In other embodiments, one fixing hole 229 can also correspond to a plurality of positioning holes 231, thus improving the stability between the quick-attachment assembly 22 and the bracket body 21.

[0068] In some embodiments, the bracket assembly 2 of the present application enables the camera 3 to move or rotate relative to the bracket body 21, so that the bracket assembly 2 of the present application is flexible to use. In some embodiments, the bracket assembly 2 of the present application fixes the position and angle of the camera 3 relative to the bracket body 21 after installation, so as to ensure that after the camera 3 is installed on the bracket assembly through the quick-release assembly 22, a good shooting effect can be achieved without adjusting the angle and position. In some embodiments, the bracket body 21 is enclosed in a polygon. Through the cooperation of the fixing post 228 and the fixing hole 229, and the cooperation of the positioning post 230 and the positioning hole 231, and the relative positions of multiple cameras 3 and the corresponding quick-release assemblies 22 are the same, so that the lenses of multiple cameras 3 face the center of the bracket body 21 at the same time, achieving a good shooting effect on the center of the bracket body 21. In the illustrated embodiment, the diameters of the fixing post 228 and the positioning post 230 are different, and the camera fixing post 228 and the camera positioning post are different, which plays a role in preventing misassembly during installation.

[0069] Please refer to Figure 2 and Figure 3 , in the illustrated embodiment, the fixing post 228 protrudes downward relative to the positioning post 230, and the diameter of the fixing post 228 is larger than that of the positioning post 230. The fixing post 228 has higher strength than the positioning post 230. The positioning post 230 is used for positioning with less force, and the fixing post 228 is used for fixing with greater force. Such a structure is reasonable and cost-saving. In the illustrated embodiment, the fixing post 228 is located in the middle of the upper plate body 225, and the positioning post 230 deviates from the center of the upper plate body 225. In this way, the fixing post 228 can firmly fix the upper plate body 225 on the bracket body 21, and the stability and safety of the bracket assembly 2 of the present application are higher.

[0070] Please refer to Figure 2 , in the illustrated embodiment, at least some of the multiple fixing holes 229 are spaced apart along the length direction of the bracket body 21, and at least some of the multiple positioning holes 231 are spaced apart along the length direction of the bracket body 21. The quick-release assembly 22 can selectively cooperate with some of the fixing holes 229 among the multiple fixing holes 229 and some of the positioning holes 231 among the multiple positioning holes 231 to change the position of the quick-release assembly 22 in the length direction of the bracket body 21. In this way, the quick-release assembly 22 can be installed on the bracket body 21 according to the use requirements to realize changing the position of the camera 3 in the length direction of the bracket body 21. In some embodiments, the present application includes multiple quick-release assemblies 22, and the number and position of the quick-release assemblies 22 can be adjusted according to the use requirements and the size of the bracket body 21.

[0071] Please refer to Figures 3-4, in the illustrated embodiment, the quick - mounting assembly 22 further includes an upper gasket 232 disposed on the lower surface of the upper plate 221 and a lower gasket 233 disposed on the upper surface of the lower plate 222. The upper gasket 232 abuts against the upper surface of the bracket body 21, and the lower gasket 233 abuts against the lower surface of the bracket body 21; the upper gasket 232 and the lower gasket 233 are made of flexible materials. In this way, the quick - mounting assembly 22 is firmly connected to the bracket body 21.

[0072] Please refer to Figure 2 and Figure 3 , in the illustrated embodiment, the lower plate 222 includes a lower gasket mounting hole 235. The lower gasket 233 is fixed within the lower gasket mounting hole 235, and the upper surface of the lower gasket 233 is higher than the upper surface of the lower plate 222. In this way, the lower gasket 233 abuts against the lower surface of the bracket body 21, ensuring that the camera 3 can be firmly fixed to the bracket body 21. In the illustrated embodiment, the upper plate 221 includes an upper gasket mounting hole 234. The upper gasket 232 is fixed within the upper gasket mounting hole 234, and the lower surface of the upper gasket 232 is lower than the lower surface of the upper plate 221. In this way, the upper gasket 232 abuts against the upper surface of the bracket body 21, ensuring that the camera 3 can be firmly fixed to the bracket body 21. In some embodiments, the edge of the lower gasket 233 is provided with a lower notch, and the edge of the upper gasket 232 is provided with an upper notch, thus saving materials.

[0073] In the illustrated embodiment, the lower plate 222 of the quick - mounting assembly 22 further includes a lower plate body 2221 and a wrench 2222 connected to the lower plate body 2221. The lower plate body 2221 is hinged to the hinge portion 223 and is provided with a locking hole 2241 for cooperating with the buckle 224. The wrench 2222 is located on the side of the lower plate body 2221 where the locking hole 2241 is provided; the locking hole 2241 and the wrench 2222 are located below the rear end of the camera 3. In this way, the quick - mounting assembly 22 and the bracket body 21 are easy to disassemble.

[0074] Please refer to Figure 2, in the illustrated embodiment, the buckle 224 includes a buckle extension 2242 extending vertically downward from the lower surface edge of the upper plate 221 perpendicular to the upper plate 221 and a buckle body 2243 provided at the lower end of the buckle extension 2242. The lower plate 222 further includes a card hole 2241 that cooperates with the buckle 224. In the locked state, the buckle body 2243 buckles the buckle 224 into the card hole 2241. Thus, the buckle 224 is set to adapt to the thickness of the bracket body 21. When the weight of the camera 3 is large and the thickness of the bracket body 21 is large, the lengths of the buckle extension 2242 and the hinge portion 223 can be extended. In some embodiments, the diameter of the buckle extension 2242 is greater than the diameter of the buckle body 2243. Thus, the buckle extension 2242 has better axial bearing capacity to ensure that the camera 3 can be firmly fixed to the bracket body 21. In some embodiments, a plurality of buckle bodies 2243 can extend downward from one buckle extension 2242. In the illustrated embodiment, the buckle body 2243 includes a first buckle body 2244 and a second buckle body 2245. The first buckle body 2244 and the second buckle body 2245 are arranged side by side and at intervals on both side edges of the buckle extension 2242 in the length direction of the bracket body 21. The card hole 2241 includes a first card hole 2246 and a second card hole 2247. The first card hole 2246 and the second card hole 2247 are arranged side by side and at intervals on the lower plate 222 in the length direction of the bracket body 21. In the locked state, the first buckle body 2244 buckles the buckle 224 into the first card hole 2246, and the second buckle body 2245 buckles the buckle 224 into the second card hole 2247. Thus, between the upper plate 221 and the lower plate 222 of the quick-release assembly 22 of the bracket assembly 2 of the present application, there are multiple connection positions (the first buckle body 2244 buckles the buckle 224 into the first card hole 2246, and the second buckle body 2245 buckles the buckle 224 into the second card hole 2247). Thus, the connection between the upper plate 221 and the lower plate 222 is tight, ensuring that the camera 3 can be firmly fixed to the bracket body 21. In the illustrated embodiment, the upper plate 221 is disc-shaped, and the buckle extension 2242 is plate-shaped and is oppositely arranged radially on the upper plate 221 with the hinge portion 223. Such a structural design is reasonable and saves materials.

[0075] In some embodiments, the side of the bracket body 21 abuts against the back of the buckle extension 2242, playing a certain self-locking function; in other embodiments, the buckling direction of the buckle body 2243 faces away from the hinge portion 223. Thus, it is convenient for disassembly and assembly. Just apply pressure to the buckle body 2243 towards the center of the quick-release assembly 22, and the buckle body 2243 can be made to enter and exit the card hole 2241.

[0076] Please refer to Figure 2, in the illustrated embodiment, the hinge portion 223 includes a first hinge portion 2231 and a second hinge portion 2232 that are spaced apart in the longitudinal direction of the bracket body 21. The first hinge portion 2231 and the second hinge portion 2232 extend vertically downward from the lower surface edge of the upper plate 221 perpendicular to the upper plate 221. Please continue to refer to Figure 4 , hinge holes 2233 are provided at the lower ends of both the first hinge portion 2231 and the second hinge portion 2232. The lower plate 222 includes a lower plate body 2221 and a hinge rotating shaft 2234 that extends upward from the edge of the lower plate body 2221. The hinge rotating shaft 2234 includes a shaft body 2235 and a rotational connection portion 2236 connected to the shaft body 2235. The shaft body 2235 is located between the first hinge portion 2231 and the second hinge portion 2232, and the rotational connection portion 2236 rotatably passes through the hinge hole 2233. This ensures the strength of the upper plate 221 and the lower plate 222 of the quick - mounting assembly 22. On the one hand, it ensures that the camera 3 can be firmly fixed to the bracket body 21. On the other hand, it facilitates the disassembly and assembly of the quick - mounting assembly 22 of the present application, and when the quick - mounting assembly 22 is not in use, the lower plate 222 is not easily lost.

[0077] The end face of the shaft body 2235 facing away from the lower plate body 2221 is an arc surface, and the surface of the lower end of the hinge portion 223 facing the bracket body 21 is an arc surface. This avoids the formation of an acute - angle between the lower plate 222 and the hinge portion 223 when the thickness of the bracket body 21 is small and there will be no collision interference. The quick - mounting assembly 22 of the present application can be applied to different bracket bodies 21, with strong versatility. On the other hand, when the size of the bracket body 21 needs to be changed due to the required shooting radius or the change of the camera 3, there is no need to replace the quick - mounting assembly 22. The quick - mounting assembly 22 is universal on various bracket bodies 21, saving materials.

[0078] In the illustrated embodiment, the bracket body 21 includes a plurality of sub - brackets 211 and a connecting member 212 that connects the plurality of sub - brackets 211. The plurality of sub - brackets 211 are connected in sequence end - to - end through the connecting member 212. Figure 5 For Figure 1 the three - dimensional schematic diagram of the sub - bracket 211 of the bracket assembly 2 in the illustrated embodiment, Figure 6 For Figure 1 the partial schematic diagram of the bracket assembly 2 including the connecting member 212 in the illustrated embodiment. Please refer to Figures 5-6 , in the illustrated embodiment, the bracket body 21 includes a plurality of sub - brackets 211, and the plurality of sub - brackets 211 are connected end - to - end in sequence. The bracket assembly 2 includes a plurality of quick - mounting assemblies 22, and the plurality of quick - mounting assemblies 22 are respectively connected to the camera 3, and at least some of the quick - mounting assemblies 22 are fixed to different sub - brackets 211. In this way, the bracket body 21 of the present application can be disassembled into a plurality of sub - brackets 211, with high portability.

[0079] In the illustrated embodiment, the number of sub-supports 211 is 18, the number of quick-attachment components 22 is 72, and the support body 21 is a regular polygon composed of 18 sub-supports 211. Please refer to Figure 5 , in Figure 5 the illustrated embodiment, the sub-support 211 includes a plurality of fixing holes 229 and a plurality of positioning holes 231. The plurality of fixing holes 229 includes a first fixing hole 2291 and a second fixing hole 2292. The plurality of positioning holes 231 includes a first positioning hole 2311 and a second positioning hole 2312. When the number of sub-supports 211 is the first number, the fixing post 228 of the quick-attachment component 22 cooperates with the first fixing hole 2291, and the positioning post 230 cooperates with the first positioning hole 2311. The included angle between adjacent sub-supports 211 is the first included angle. The optical axes of the cameras carried by the quick-attachment components 22 on the plurality of sub-supports 211 intersect at the center of the circle tangent to the plurality of sub-supports 211; when the number of sub-supports 211 is the second number different from the first number, the fixing post 228 cooperates with the second fixing hole 2292. The included angle between adjacent sub-supports 211 is the second included angle different from the first included angle. The optical axes of the cameras carried by the quick-attachment components 22 on the plurality of sub-supports 211 intersect at the center of the circle tangent to the plurality of sub-supports 211, which can be the center of the polygon formed by the plurality of sub-supports 211. When the number of sub-supports 211 is different, the overall dimensions of the formed support body 21 are different. The first positioning hole 2311 and the second positioning hole 2312 of the present application can adapt to support bodies 21 of different sizes, and can all achieve direct centering after the camera is installed on the support body 21, reducing the centering time of the operator and greatly improving the installation efficiency.

[0080] In the illustrated embodiment, the number of quick-attachment components 22 is 72, and they are evenly distributed at intervals of 5°. For example, when the number of sub-supports 211 is 18, a support body 21 in the shape of a polygon with an inscribed or circumscribed circle radius of 3 m can be assembled, and 4 quick-attachment components 22 are fixedly installed on each sub-support 211. When the number of sub-supports 211 is 36, a support body 21 in the shape of a polygon with an inscribed or circumscribed circle radius of 6 m can be assembled, and 2 quick-attachment components 22 are fixedly installed on each sub-support 211. When the number of sub-supports 211 is 72, a support body 21 in the shape of a polygon with an inscribed or circumscribed circle radius of 12 m can be assembled, and 1 quick-attachment component 22 is fixedly installed on each sub-support 211.

[0081] Please refer to Figure 5, the shapes of the sub-brackets 211 in the above three cases are the same, and the sub-bracket 211 is provided with 7 fixing holes 229. Corresponding to the above three cases: 4 fixing holes 229 are used for fixing the quick-installing component 22 when the radius is 3m, 2 fixing holes 229 are used for fixing the quick-installing component 22 when the radius is 6m, and one fixing hole 229 is used for fixing the quick-installing component 22 when the radius is 12m. The sub-bracket 211 is respectively marked with corresponding radius markings for a plurality of fixing holes 229, indicating the radius in the corresponding case. In this way, the installation is convenient, and it only needs to install the quick-installing component 22 into the fixing hole 229 with the corresponding marking in the corresponding embodiment. In some embodiments, the bracket assembly 2 can also be set as a line segment, for example, set as an arc shape covering a range of 120°. In some embodiments, the bracket assembly 2 can support the customer to customize the number of camera 3 configurations, the orientation angle, the interval angle, and the coverage angle by themselves, for example, 360° panoramic shooting can be realized. In the illustrated embodiment, the sub-bracket 211 is axially symmetrically designed, so there is no need to distinguish between the front and the back when connecting. In some embodiments, the sub-bracket 211 is machined from aluminum profiles, and has the advantages of high strength, light weight, and convenient storage.

[0082] Figure 7 is Figure 1 a three-dimensional schematic view of the connecting member 212 of the bracket assembly 2 of the illustrated embodiment, Figure 8 is Figure 1 a side view of the connecting member 212 of the bracket assembly 2 of the illustrated embodiment, Figure 9 is Figure 1 a top view of the connecting member 212 of the bracket assembly 2 of the illustrated embodiment. Please refer to Figure 6 and Figure 7 , the bracket body 21 includes a plurality of sub-brackets 211 and a connecting member 212 connecting the plurality of sub-brackets 211. The plurality of sub-brackets 211 are sequentially connected end to end through the connecting member 212, and adjacent sub-brackets 211 can rotate relative to each other through the connecting member 212. In the illustrated embodiment, the connecting member 212 includes an upper connecting member 2121 and a lower connecting member 2122. The upper connecting member 2121 is connected to the end of one of the adjacent two sub-brackets 211, and the lower connecting member 2122 is connected to the end of the other of the adjacent two sub-brackets 211.

[0083] Please refer to Figure 7 and Figure 9, in some embodiments, the upper connecting member 2121 and the lower connecting member 2122 are in contact through a high-precision gear disk structure to achieve precise adjustment of the angle of the component. At this time, the lower surface of the upper connecting member 2121 is provided with upper end face teeth 2123, and the upper surface of the lower connecting member 2122 is provided with lower end face teeth 2124. The upper end face teeth 2123 and the lower end face teeth 2124 are rotatably matched to change the angle between two adjacent branch brackets 211. In this way, the angle between the branch brackets 211 can be adjusted, and the bracket body 21 with different shapes can be built by adjusting the angle between the branch brackets 211. In some embodiments, the angle adjustment range between two branch brackets 211 is 158° - 178°, and for each tooth turned, the relative angle changes by 5°.

[0084] In the illustrated embodiment, the upper connecting member 2121 has a first angular position and a second angular position relative to the lower connecting member 2122. The branch bracket 211 includes a first fixed position and a second fixed position, and the first fixed position and the second fixed position are distributed in the length direction of the branch bracket 211. When the number of multiple branch brackets 211 is the first number, the upper connecting member 2121 is located at the first angular position relative to the lower connecting member 2122, and the quick installation component 22 is fixed to the first fixed position. When the number of multiple branch brackets 211 is a second number different from the first number, the upper connecting member 2121 is located at the second angular position relative to the lower connecting member 2122, and the quick installation component 22 is fixed to the second fixed position. In this way, the bracket component 2 of the present application has strong compatibility. In the illustrated embodiment, the number of quick installation components 22 is 72. In one embodiment, when the number of branch brackets 211 is 18, a regular polygon bracket body 21 with a radius of 3 m can be assembled. The included angle between every two branch brackets 211 is 160°, and each branch bracket 211 fixes 4 quick installation components 22; when the number of branch brackets 211 is 36, a regular polygon bracket body 21 with a radius of 6 m can be assembled. The included angle between every two branch brackets 211 is 170°, and each branch bracket 211 fixes 2 quick installation components 22; when the number of branch brackets 211 is 72, a regular polygon bracket body 21 with a radius of 12 m can be assembled. The included angle between every two branch brackets 211 is 175°, and each branch bracket 211 fixes one quick installation component 22. In some embodiments, corresponding radius markings can be set at the first angular position and the second angular position of the relative angle between the upper connecting member 2121 and the lower connecting member 2122. For example, in the above three cases, silk screens are engraved at 160°, 170°, and 175°. In this way, the installation is convenient, and only by aligning the silk screens of the upper connecting member 2121 and the lower connecting member 2122 can the construction of the regular polygon bracket body 21 with the corresponding radius be achieved.

[0085] Please refer to Figures 7-9In the illustrated embodiment, the connecting member 212 includes a connecting fixing member 213, and the connecting fixing member 213 connects the upper connecting member 2121 and the lower connecting member 2122, and locks or releases the upper connecting member 2121 and the lower connecting member 2122. When the connecting fixing member 213 releases the upper connecting member 2121 and the lower connecting member 2122, the upper connecting member 2121 and the lower connecting member 2122 can rotate relatively through the upper end face teeth 2123 and the lower end face teeth 2124. In this way, the upper connecting member 2121 and the lower connecting member 2122 can rotate relatively, and the conversion between the adjustable state and the locked state of the upper and lower joints is realized by loosening and tightening the connecting fixing member 213. With the engagement of the upper end face teeth 2123 and the lower end face teeth 2124, the angle between the upper connecting member 2121 and the lower connecting member 2122 is fixed after the connecting fixing member 213 is locked. In some embodiments, when the connecting fixture 213 is loosened counterclockwise, the upper connecting member 2121 and the lower connecting member 2122 are separated by a certain distance to adjust the angle, and the silk-screen indication of the angle corresponding to the radius is matched. After the required radius adjustment is completed, the connecting fixture 213 is tightened clockwise, and the end teeth of the upper connecting member 2121 and the lower connecting member 2122 are pressed and meshed to complete the upper and lower locking. Furthermore, the threaded hole of the lower connecting member 2122 is provided with an anti-drop structure to prevent the upper connecting member 2121 and the lower connecting member 2122 from falling out due to excessive loosening.

When the button 2192 is pressed, the inverted buckle 217 moves into the clamping portion 219 and separates from the inverted buckle hole 218. In this way, the connection between the sub-brackets 211 is stable and easy to disassemble and assemble. In some embodiments, the buckle 224 is provided with an inclined surface. After the two ends of the sub-bracket 211 are inserted, the buckle 224 is automatically latched with the inverted buckle hole 218 of the bracket fixing portion 215 through the guidance of the inclined surface, realizing the locking and fixing of the connecting member 212 and the sub-bracket 211; when it is necessary to disassemble the sub-bracket 211, pressing down the elastic piece 2191 can sink the buckle 224, and the sub-bracket 211 can be pulled out.
