Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the described features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "installed," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0034] refer to Figure 1 The present invention provides a novel center axis assembly 10 for connecting a photographic device to a tripod. The center axis assembly 10 stabilizes the photographic device's shooting angle and aligns the tripod's center of gravity to prevent tipping. Using the center axis assembly 10 with a tripod for shooting can adapt to a variety of scenarios, allowing users to switch between different modes based on their needs, providing a superior user experience.

[0035] Combined with reference Figure 1 and Figure 2The central axis assembly 10 of the present application includes a detachably connected central axis 100, a hook 200, and a tool shaft 300. The central axis 100 serves as the main shaft of the central axis assembly 10 and is provided with a receiving slot 110. The hook 200 is detachably connected to the bottom end of the central axis 100, allowing heavy objects to be hung on the hook 200, increasing the weight of the photography tripod and acting as a counterweight to prevent the photography tripod from being blown over by strong winds. The tool shaft 300 can be stored in the receiving slot 110, achieving a detachable connection to the central axis 100. Here, the central axis 100, hook 200, and tool shaft 300 are capable of being detached from each other and existing independently. When the tool shaft 300 is released from the receiving slot 110 and the hook 200 is detached from the central axis 100, the tool shaft 300 can be switchably mounted between at least the first mounting position 201 and the second mounting position 202 of the hook 200. In other words, the tool shaft 300 can be detachably mounted at different positions on the hook 200 to form different types of disassembly and assembly tools 23. In this disassembly and assembly tool 23, the hook 200 and tool shaft 300 are circumferentially limited, allowing a user to rotate the hook 200 and drive the tool shaft 300 to rotate synchronously to disassemble or assemble photographic accessories. Here, the number of mounting positions may also be two or more.

[0036] Combined with reference Figure 3 and Figure 4 In the present application, when the tool shaft 300 is installed in the first mounting position 201 and the second mounting position 202, the angles formed between the axial direction of the tool shaft 300 and the length direction of the hook 200 at the two different mounting positions are different, so that the torque of the disassembly tool 23 changes, thereby adapting to the disassembly and assembly of more different photographic accessories, which is convenient and labor-saving. Specifically, the tool shaft 300 has a connecting end 310 and a functional end 320 that are opposite to each other along its axial direction. The connecting end 310 is used for detachable installation in the first mounting position 201 or the second mounting position 202, and the functional end 320 is used to disassemble and assemble photographic accessories through the synchronous rotation of the hook 200 and the tool shaft 300 when the hook 200 is held. The functional end 320 of the tool shaft 300 in the present application is not limited, and includes but is not limited to a wrench head or a screwdriver. In addition, the functional end can also be connected to multiple disassembly heads of different types or specifications along the axial direction of the tool shaft 300. In this embodiment, the connecting end 310 is a conventional hexagonal socket wrench head.

[0037] The central axis assembly 10 provided in the present application, on the one hand, integrates the tool shaft 300 into the central axis 100, allowing users to disassemble and assemble photographic accessories without having to carry an additional disassembly and assembly tool 23. On the other hand, the tool shaft 300 can be detachably mounted at different positions of the hook 200 (the first mounting position 201 and the second mounting position 202) to change the torque of the disassembly and assembly tool 23 to meet the disassembly and assembly of photographic accessories at different positions on the support tripod, saving time and effort. Therefore, the central axis assembly 10 of the present application has a detachable hook 200 and a tool shaft 300, and the hook 200 and the tool shaft 300 can be flexibly assembled to form a disassembly and assembly tool 23 with different torques, which is very practical.

[0038] Preferably, reference Figure 5 In this embodiment, the bottom end of the central shaft 100 is recessed along its axial direction to form a receiving groove 110. The hook 200 includes a connecting portion 210 and a hook portion 220 connected along its length. The connecting portion 210 is detachably connected to the bottom end of the central shaft 100 and can cover the tool shaft 300 within the receiving groove 110, thus making the entire central shaft assembly 10 compact. The hook portion 220 is used to attach a heavy object. It is understood that in other embodiments, the receiving groove 110 can be located at other locations on the central shaft 100. Therefore, the location and formation of the receiving groove 110 are not limited in this application.

[0039] Preferably, in combination with reference Figure 2 and references Figure 5 The first mounting position 201 and the second mounting position 202 are both located on the connecting portion 210. The first mounting position 201 includes a first mounting hole 211, and the second mounting position 202 includes a second mounting hole 212. The first mounting hole 211 and the second mounting hole 212 form an angle in their depth directions. The connecting end 310 is inserted into the first mounting hole 211 or the second mounting hole 212 to enable the tool shaft 300 to be switchably mounted on the hook 200, thereby changing the rotational torque of the disassembly tool 23. It should be noted that the inner sidewalls of the first mounting hole 211 and the second mounting hole 212 are both adapted to the side circumferential profile of the outer sidewall of the connecting end 310 to achieve circumferential positioning of the tool shaft 300 around its axis and the hook 200. Here, the connecting end 310 includes but is not limited to hexagonal prisms, quadrangular prisms, triangular prisms, and threaded segments, while the first mounting hole 211 and the second mounting hole 212 are correspondingly hexagonal axial holes, quadrangular axial holes, triangular axial holes, axial holes with internal threads, etc. In the present application, firstly, the implementation method of the first mounting position 201 and the second mounting position 202 is not limited, that is, whether the first mounting position 201 and the second mounting position 202 are set or not is not limited; secondly, the formation state of the connecting end 310, the first mounting hole 211 and the second mounting hole 212 is not limited, it is only necessary to meet the requirements that the tool shaft 300 can be switchably installed in different mounting positions of the hook 200.

[0040] Preferably, in combination with reference Figure 2 and Figure 5 In this embodiment, the end surface of the connecting portion 210, away from the hook portion 220, is recessed to form the aforementioned first mounting hole 211. When the connecting portion 210 is connected to the bottom end of the central shaft 100, the depth direction of the first mounting hole 211 is parallel to the axial direction of the central shaft 100. The first mounting hole 211 is aligned and connected to the receiving groove 110 along the axial direction of the central shaft 100. A portion of the tool shaft 300 is received in the receiving groove 110, and the other portion of the tool shaft 300 is received in the first mounting hole 211. This design makes the central shaft assembly 10 more compact and stable when receiving the tool shaft 300. The first mounting hole 211 can not only be used to receive a portion of the tool shaft 300, but can also be used to connect the tool shaft 300 to the hook 200 to form the disassembly tool 23. Therefore, the first mounting hole 211 has a dual function. It can be understood that, without considering the compactness and stability of the structure of the central axis assembly 10, in this application, the setting position of the first mounting hole 211 is not limited. In other embodiments, the first mounting hole 211 can also be set at other positions of the connecting part 210.

[0041] Preferably, in combination with reference Figure 2 and Figure 5 The side wall surface of the connecting portion 210 near the hook portion 220 is recessed to form the second mounting hole 212 mentioned above. When the connecting portion 210 is connected to the bottom end of the central axis 100, the depth direction of the second mounting hole 212 is perpendicular to the depth direction of the first mounting hole 211 (the axial direction of the central axis 100), and the first mounting hole 211 and the second mounting hole 212 are not connected to each other in the connecting portion 210. The above design allows the processing and formation of the first mounting hole 211 and the second mounting hole 212 to not interfere with each other, making the volume of the connecting portion 210 smaller and lighter. It is understandable that in the present application, the angle between the depth direction of the first mounting hole 211 and the second mounting hole 212 does not necessarily need to be perpendicular. It only needs to be in an angled state to change the torque of the disassembly tool 23.

[0042] Preferably, in combination with reference Figure 2 and Figure 5, the connecting end 310 includes metal, and the central axis assembly 10 also includes a magnet 400. The magnet 400 is arranged in the connecting portion 210. When the tool shaft 300 is inserted into the first mounting hole 211 or the second mounting hole 212, the magnet 400 can magnetically attract the connecting end 310 to enhance the connection stability between the tool shaft 300 and the hook 200. Furthermore, the connecting portion 210 is provided with a placement groove 213 on the bottom wall of the first mounting hole 211 and / or the bottom wall of the second mounting hole 212. The placement groove 213 is used to accommodate the magnet 400. In addition, in this embodiment, the number of magnets 400 and the placement groove 213 are both two and one-to-one corresponding. It can be understood that, without considering the connection stability of the tool shaft 300, in this application, whether the magnet 400 and the placement groove 213 are provided or not is not limited.

[0043] Combined with reference Figure 2 and Figure 5 The central shaft assembly 10 further includes a sealing ring 500, which is sleeved onto the outer wall of the connecting portion 210. When the hook 200 is connected to the bottom end of the central shaft 100, that is, when the connecting portion 210 covers the receiving groove 110, the connecting portion 210 forms an interference fit with the inner wall of the receiving groove 110 via the sealing ring 500, thereby enhancing the connection stability between the hook 200 and the central shaft 100. It should be noted that the sealing ring 500 is made of an elastic material and can elastically deform to simultaneously abut the outer wall of the connecting portion 210 and the inner wall of the receiving groove 110, thereby achieving an interference fit between the connecting portion 210 and the receiving groove 110. In other embodiments, the connecting portion 210 itself can be made of an elastic material to similarly achieve an interference fit between the connecting portion 210 and the receiving groove 110, further enhancing the connection stability between the hook 200 and the central shaft 100. Of course, in other embodiments, the central shaft assembly 10 can achieve the connection between the hook 200 and the central shaft 100 without the sealing ring 500. It is understandable that, without considering the stability of the connection between the hook 200 and the central axis 100, in the present application, there is no limitation on whether the sealing ring 500 is provided or not, and it is only necessary that the connecting portion 210 can be detachably covered on the accommodating groove 110.

[0044] refer to Figure 6The present invention also provides a photographic stand 1, comprising a mounting base 20, a plurality of support legs 30, and the aforementioned central axis assembly 10. The plurality of support legs 30 are connected to the mounting base 20 and arranged at an angle along the circumference. The central axis assembly 10 is inserted through the mounting base 20 to serve as the central axis 100 of the photographic stand 1. It should be noted that, first, in this embodiment, the central axis assembly 10 is detachably connected to the photographic stand 1. It is understood that in other embodiments, the central axis assembly 10 may be fixedly connected to the photographic stand 1, or the central axis assembly 10 may be movably connected to the mounting base 20, in which case the central axis assembly 10 is movable relative to the mounting base 20 in the axial direction thereof, i.e., the central axis assembly 10 is movable vertically up and down. Secondly, in this embodiment, the support legs 30 are rotatably connected to the mounting base 20, enabling switching between an extended state and a retracted state. In the extended state, the photographic stand 1 has a tripod structure. It is understood that in other embodiments, the support leg 30 may also be fixedly connected to the mounting base 20 .

[0045] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive.
