Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a handheld device for photographic equipment. Background Technology

[0002] Handheld devices, as key accessories for photographic equipment such as cameras and camcorders, are usually mounted on the top of the equipment, providing photographers with a stable and convenient grip. This allows photographers to easily lift the equipment during shooting, especially when they need to move quickly or change shooting positions, making it easier for them to carry the equipment.

[0003] To further enhance the functionality of photography equipment, handheld devices on the market have added external interfaces for connecting external focus rangefinders, microphones, fill lights, and other photography auxiliary equipment. This allows photographers to supplement light in low-light environments, accurately measure focus, or record high-quality audio, meeting the diverse needs of different scenarios such as landscape photography, portrait photography, and documentary shooting.

[0004] Currently, the functional expansion methods of existing handheld devices are relatively fixed, making it difficult to flexibly adjust them according to different shooting scenarios and actual needs. For example, in landscape photography, photographers may need to install fill lights and wide-angle lenses; while in portrait photography, the focus is more on installing accessories such as microphones and softboxes; and in documentary filmmaking, multiple auxiliary devices may need to be used simultaneously. Existing handheld devices often cannot easily combine and disassemble accessories, resulting in poor flexibility and difficulty in meeting the diverse needs of different shooting scenarios. In addition, the fixed accessory installation method increases the overall weight and size of the equipment, causing inconvenience to photographers in actual use and reducing shooting efficiency.

[0052] Please refer to Figure 1 and Figure 2 This application provides a portable device 100 for a photography equipment, including a main body 10, which is elongated. The main body 10 is provided with a first connecting structure 11 and a second connecting structure 12. The first connecting structure 11 and / or the second connecting structure 12 are used to connect an expansion component 20. The expansion component 20 is provided with at least one mounting interface 200, which is adapted to photography auxiliary accessories.

[0053] The main body 10 is elongated and serves as the core load-bearing component of the carrying device 100. Its main functions are twofold: first, to provide an ergonomic grip for stable lifting and operation of the photographic equipment; and second, to integrate the first connecting structure 11 and the second connecting structure 12, providing a mounting base for the expansion component 20. The first connecting structure 11 and the second connecting structure 12 can employ standardized interface designs (such as snap-fit, magnetic, or threaded types) to quickly connect with different types of expansion components 20, ensuring a stable connection and easy disassembly, while also ensuring that the main body 10's grip is not affected by the installation of the expansion component 20 during transport.

[0054] As a key component for functional expansion, the expansion component 20 connects to the main body 10, providing a mounting platform for photographic auxiliary accessories. Each expansion component 20 has at least one mounting interface 200, which is specifically designed according to the size and connection requirements of common photographic auxiliary devices (such as focus rangefinders, microphones, and fill lights), supporting quick plug-in / unplugging or rotation locking to ensure secure installation and easy replacement of accessories. Furthermore, the expansion component 20 can be designed in various types to suit different shooting scenarios. For example, an expansion component 20 emphasizing fill light functionality can be equipped with multiple fill light interfaces and a power adapter module, while an expansion component 20 emphasizing audio recording functionality optimizes the microphone interface layout and noise reduction design to meet diverse shooting needs.

[0055] The portable device 100 for photography equipment provided in this application adopts a modular design concept. Through a combined architecture of the main body 10 and the expansion component 20, it achieves flexible functional expansion and scene adaptation. The main body 10 serves as the basic load-bearing structure and is detachably connected to the expansion component 20 via a first connecting structure 11 and a second connecting structure 12. The mounting interface 200 on the expansion component 20 can accommodate various photography accessories. This design breaks down the traditional fixed structure into replaceable modules, allowing users to freely combine accessories according to shooting scene requirements, thus solving the problems of limited functionality and poor adaptability of existing devices.

[0056] The portable device 100 for the photography equipment provided in this application features a first connecting structure 11 and a second connecting structure 12 on a long, narrow main body 10. The first connecting structure 11 and / or the second connecting structure 12 can be connected to an expansion component 20. The mounting interface 200 on the expansion component 20 is compatible with various photography accessories. Through a modular connection design, photography accessories with different functions can be freely combined with the main body 10, breaking the limitations of traditional fixed installation methods. Users can quickly disassemble or replace photography accessories such as fill lights, microphones, and wide-angle lenses according to different shooting scenarios such as landscapes, portraits, and documentaries, achieving flexible switching of shooting functions. Moreover, the modular structure reduces unnecessary accessory installation, effectively reducing the overall weight and size of the equipment, and improving shooting portability and efficiency.

[0057] In some embodiments, the mounting interface 200 includes one or more of the following: a cold shoe interface, a threaded connection, a pipe clamp, and an Arri interface.

[0058] Among them, the mounting interface 200 is a key part of the expansion component 20 for connecting photography auxiliary accessories. By integrating one or more of the following, such as cold shoe interface, threaded connection, tube clamp, and Arri interface, it enables the quick installation and removal of various photography accessories such as fill lights, microphones, monitors, and follow focus devices, meeting the needs of different shooting scenarios for expanding equipment functions.

[0059] Specifically, the cold shoe interface adopts a standard slot and buckle structure, which quickly fixes accessories with cold shoe bases, such as fill lights and microphones, through mechanical fastening, allowing for tool-free installation and removal; the threaded connection is based on the thread engagement principle, and provides a high-strength fixed connection by cooperating with the standard threads (such as 1 / 4 inch or 3 / 8 inch threads) on the bottom of the accessory, which is suitable for heavier photography accessories, such as monitors and telephoto lens brackets; the tube clamp fixes cylindrical accessories (such as photography light poles and microphone arms) to the expansion assembly 20 through elastic clamping or knob tightening, and the clamping force can be adjusted to accommodate different tube diameters; the ARRI interface adopts a standardized positioning pin and groove 114 cooperation design to achieve precise alignment and quick locking of photography accessories and interfaces, which is often used for stable connection of professional photography equipment.

[0060] It should be noted that the cold shoe interface, threaded connection, etc., mentioned above are merely exemplary examples of the installation interface 200 types listed in this application embodiment. Based on the modular expansion design concept of this device, the installation interface 200 can also adopt other forms such as magnetic interface, dovetail interface, quick-release buckle, etc., according to actual needs. This application embodiment does not limit the specific type and structure of the installation interface 200.

[0061] In some embodiments, the first connecting structure 11 is a slide rail 111, which is located on one side of the main body 10. The extension component 20 includes a first extension component 21, which includes a first connecting arm 211. The first connecting arm 211 is provided with a first mating structure 212 that cooperates with the slide rail 111. The first connecting arm 211 is slidably connected to the main body 10 through the first mating structure 212.

[0062] The slide rail 111 on one side of the main body 10 serves as a basic connecting component, and its main function is to provide guidance and fixation for the first extension component 21. The groove design of the slide rail 111 not only restricts the movement direction of the first connecting arm 211, ensuring that the extension component 20 will not shift or shake during installation and use, but also prevents the first connecting arm 211 from accidentally falling off through the internal limiting structure (such as the stop groove).

[0063] The first connecting arm 211 serves as the connection hub between the first extension component 21 and the main body 10. Its first mating structure 212 (such as a slider 213) forms a tight fit with the slide rail 111. During installation, the user simply aligns the slider 213 of the first connecting arm 211 with the groove of the slide rail 111 and pushes it in along the track direction to complete the connection. Disassembly is simple and intuitive; sliding in the opposite direction separates the components. Simultaneously, the first connecting arm 211 also serves to evenly transmit the weight and external force of the extension component 20 to the main body 10, ensuring the stability of the overall structure.

[0064] In this embodiment, the sliding connection between the slide rail 111 and the first mating structure 212 eliminates the need for screws or other tools, enabling the first expansion component 21 to be used immediately. Users can quickly replace the first expansion component 21 with different functions on-site (e.g., switching from the fill light expansion component 20 to the audio recording expansion component 20), significantly reducing equipment adjustment time. Furthermore, through the sliding operation, users can freely adjust the position of the expansion component 20 on the main body 10, for example, adjusting the fill light expansion component 20 closer to the subject to optimize the fill light effect.

[0065] Furthermore, the design of the slide rail 111, mounted on one side of the main body 10, does not occupy the top grip space of the main body 10, ensuring that the user can still comfortably hold the device after installing the expansion component 20. In addition, the slide rail 111 can support the series installation of multiple first expansion components 21, such as simultaneously installing the fill light expansion component 20 and the microphone expansion component 20, to meet the multi-functional needs in complex shooting scenarios and further enhance the expandability of the device.

[0066] In some embodiments, the second connecting structure 12 is disposed at one end of the main body 10, the extension component 20 includes a second extension component 22, the second extension component 22 includes a second connecting arm 221, one end of the second connecting arm 221 is provided with a second mating structure 222 that cooperates with the second connecting structure 12, and the second connecting arm 221 is detachably connected to the main body 10 through the second mating structure 222.

[0067] The main function of the second connecting structure 12 located at one end of the main body 10 is to provide a stable mounting base and connection point for the second expansion component 22. It has internal structures such as positioning slots, magnetic modules, or threaded holes, which can tightly engage or attract with the second mating structure 222. For example, if a snap-on design is used, the slot can restrict the degree of freedom of movement of the second connecting arm 221, ensuring that the expansion component 20 will not shift in the horizontal or vertical directions; if a magnetic design is used, the strong magnetic force can ensure that the expansion component 20 maintains a stable connection under normal external forces. Furthermore, the material of the second connecting structure 12 can be a high-strength and wear-resistant alloy or engineering plastic, ensuring that the connection accuracy and reliability are maintained even after multiple disassemblies and reassemblies.

[0068] The second connecting arm 221 serves as the connection carrier between the second expansion component 22 and the main body 10. The second mating structure 222 (such as a hook, magnetic block, or threaded post) at one end complements the second connecting structure 12 of the main body 10. Taking a snap-fit ​​type as an example, the hook of the second connecting arm 221 can be inserted into the slot of the main body 10 by pressing or rotating, making operation convenient and the connection secure. The magnetic mating structure 222 can automatically align using magnetic force, simplifying the installation process. The second connecting arm 221 not only transmits the weight and external force of the expansion component 20 but also serves as an extension platform for installing photographic auxiliary accessories. For example, when the second expansion component 22 is a fill light module, the second connecting arm 221 must ensure that the installation angle adjustment of the fill light is not affected by the main body 10, while evenly distributing the vibration or force of the fill light to the main body 10 to maintain overall stability.

[0069] In this embodiment, the detachable design of the second connecting structure 12 allows users to quickly replace the second extension component 22 in different shooting scenarios. For example, when switching from landscape photography to portrait photography, the wide-angle lens auxiliary extension component 20 can be quickly detached, and the second extension component 22, which combines a diffuser and a microphone, can be installed without complicated tools or cumbersome steps, significantly improving shooting efficiency and helping users respond to scene changes in a timely manner.

[0070] Furthermore, the second connection structure 12 is located at one end of the main body 10, without occupying the central gripping area of ​​the main body 10. This maximizes space utilization while ensuring the photographer's grip comfort. Simultaneously, diverse connection methods (clasp, magnetic, threaded) accommodate second expansion components 22 of varying weights and sizes, enabling stable connections from lightweight microphone expansion components 20 to heavier fill light equipment, meeting the installation needs of various photographic accessories.

[0071] In some embodiments, the first connecting structure 11 is a slide rail 111, which is located on one side of the main body 10, and the second connecting structure 12 is disposed at one end of the main body 10.

[0072] Extension component 20 includes:

[0073] The first extension component 21 includes a first connecting arm 211, the first connecting arm 211 is provided with a first mating structure 212 that cooperates with the slide rail 111, and the first extension component 21 is slidably connected to the main body 10 through the first mating structure 212.

[0074] The second extension component 22 includes a second connecting arm 221. One end of the second connecting arm 221 is provided with a second mating structure 222 that cooperates with the second connecting structure 12. One end of the second connecting arm 221 is detachably connected to the main body 10 through the second mating structure 222, and the other end of the second connecting arm 221 is detachably connected to the first connecting arm 211.

[0075] The first connecting structure 11 is set on one side of the main body 10 in the form of a slide rail 111, and the first expansion component 21 is linearly slidably installed through the first mating structure 212; the second connecting structure 12 is located at one end of the main body 10 and can be connected to the second connecting arm 221 of the second expansion component 22 by means of snap-fit, magnetic attraction or thread; at the same time, the other end of the second connecting arm 221 is detachably connected to the first connecting arm 211, thereby forming a closed loop structure of the main body 10, the first expansion component 21 and the second expansion component 22.

[0076] This application embodiment allows users to freely combine the expansion component 20 in horizontal, vertical, and depth directions through lateral sliding, end plugging, and component interconnection. For example, in documentary filming, the microphone expansion component 20 can be vertically installed at the end of the main body 10 via the second connecting structure 12, while the fill light expansion component 20 can be slid along the slide rail 111 to a suitable position and connected to the first connecting arm 211 via the second connecting arm 221, realizing a three-dimensional layout of multiple devices and accurately meeting the needs of complex scenarios.

[0077] When the first connecting arm 211, the second connecting arm 221, and the main body 10 form a closed loop structure, the components support and constrain each other. When multiple heavy photography accessories (such as large fill lights and telephoto lens stabilizers) are installed, the force can be evenly transmitted and distributed within the closed loop, avoiding structural deformation or loosening caused by single-point force, greatly improving the shock resistance and stability of the device during shooting, and ensuring equipment safety and stable shooting images even in violent shooting scenarios.

[0078] In some embodiments, the main body 10 is further provided with a third connecting structure 13, which is located on one side of the main body 10;

[0079] The expansion component 20 also includes a third expansion component 23, which includes a housing 231. The housing 231 is provided with a third mating structure 232 that mates with the third connection structure 13. The housing 231 is detachably connected to the main body 10 through the third mating structure 232.

[0080] The third expansion component 23 uses a lightweight alloy or engineering plastic housing 231 as its carrier, and its surface can be distributed with standard mounting interfaces 200 such as 1 / 4-inch threaded holes and cold shoe interfaces to adapt to devices such as monitors, wireless image transmission modules, and spare battery compartments. In addition, some housings 231 adopt a split structure, which can be disassembled into two parts: a bracket and an equipment compartment, which are used to support large accessories (such as softboxes) or to store small accessories (such as lens caps and memory cards).

[0081] In this embodiment, by adding the third expansion component 23, the handheld device 100 can simultaneously carry different functional modules on both sides and at the ends of the main body 10, forming a three-dimensional working area. For example, in documentary filming, a microphone expansion component 20 (via the second connection structure 12) can be installed on the left side of the main body 10, a follow focus (first connection structure 11) can be installed on the right side, and the third expansion component 23 carries a wireless image transmission module, enabling multi-device collaborative operation and thus improving filming efficiency.

[0082] In some embodiments, the mounting interface 200 is a receiving cavity 233 formed in the housing 231, the receiving cavity 233 being used to receive a photographic auxiliary accessory, which is a controller for controlling the photographic equipment to take pictures.

[0083] The receiving cavity 233 is custom-grooved according to the shape and functional requirements of the photography auxiliary accessories (such as shooting controllers), and the controller can be precisely fixed through internal positioning bosses, buckles or magnetic structures. This design breaks through the traditional surface mounting mode, completely embedding the controller inside the housing 231, using the housing 231 to provide physical protection to prevent the controller from being damaged by collisions or scratches during shooting.

[0084] In this embodiment, the embedded cavity 233 design provides the controller with all-around protection from the housing 231. Compared with traditional external installation, this reduces the damage rate of the device caused by collisions and does not occupy external space. This allows the third expansion component 23 to achieve functional integration while maintaining a compact size.

[0085] Please refer to Figures 3 to 6 In some embodiments, the exposed side of the slide rail 111 is provided with a plurality of grooves 114 at intervals, and the first mating structure 212 is a slider 213, the slider 213 having a through hole 214 communicating with the grooves 114 inside.

[0086] The carrying device 100 also includes a locking assembly 30 for locking or unlocking the first connecting arm 211 and the body 10, the locking assembly 30 including:

[0087] The locking member 31 is located in the through hole 214 and has a locking part 311 that is adapted to the groove 114;

[0088] The abutment 32 has one side in contact with the locking member 31, and the other side of the abutment 32 can abut against the locking member 31 after being subjected to force;

[0089] The pressing member 33 is located inside the slider 213 and is in contact with the supporting member 32. The pressing member 33 can move relative to the slider 213 to drive the supporting member 32 to move.

[0090] The first reset member 34 acts on the pressing member 33 and is used to provide the pressing member 33 with a force to reset it.

[0091] The grooves 114 spaced apart on the exposed surface of the slide rail 111 and the through holes 214 inside the slider 213 together form the basic structure of the locking assembly 30, providing a positioning basis for locking the first connecting arm 211 to the main body 10. The grooves 114 are used to define the insertion position of the locking member 31, realizing the precise positioning of the first connecting arm 211 on the slide rail 111; the through holes 214 serve as the movement channel of the locking member 31, while ensuring the smooth cooperation between the locking member 31 and the grooves 114, ensuring the stability and reliability of the first connecting arm 211 in the locked state.

[0092] The grooves 114 can be designed with equal spacing or distributed as needed, corresponding to the common installation positions of photographic auxiliary accessories, making it easy for users to quickly position the first connecting arm 211 in the appropriate position. The through hole 214 inside the slider 213 is coaxially arranged with the groove 114. When the first connecting arm 211 slides along the slide rail 111, the locking member 31 inside the slider 213 can move freely within the through hole 214; when the slider 213 moves to the corresponding position of the groove 114, the locking member 31 is embedded into the groove 114 under external force, forming a mechanical lock, restricting the movement of the slider 213 along the slide rail 111, thereby locking the first connecting arm 211.

[0093] The locking member 31 has a locking part 311 that is adapted to the groove 114. By embedding into the groove 114 of the slide rail 111, the slider 213 is fixedly connected to the slide rail 111, thereby restricting the movement of the first connecting arm 211 and ensuring that the photography auxiliary accessory remains stable during shooting. At the same time, in the unlocked state, the locking member 31 can disengage from the groove 114, allowing the first connecting arm 211 to slide freely and realize position adjustment.

[0094] The supporting member 32 mainly serves to transmit pressure and fix the locking member 31. One side of it is in close contact with the locking member 31, and the other side is displaced under the action of the pressing member 33. By pressing or releasing the locking member 31, the locking and unlocking control of the first connecting arm 211 is realized. At the same time, the supporting member 32 can also constrain the movement direction of the locking member 31 to ensure that the locking member 31 is accurately inserted into or disengaged from the groove 114.

[0095] The pressing member 33 serves as the direct component operated by the user. By moving relative to the slider 213, it drives the abutment member 32 to move, thereby controlling the insertion and disengagement of the locking member 31, and realizing the locking or unlocking function of the first connecting arm 211 and the main body 10.

[0096] The main function of the first reset member 34 is to provide a reset force for the pressing member 33, ensuring that after the unlocking operation is completed, the pressing member 33 can automatically return to the initial position, so that the holding member 32 can press against the locking member 31 again, thereby realizing the automatic locking of the first connecting arm 211; at the same time, its reset force can maintain the tight contact between the locking member 31 and the groove 114, enhancing the stability of the connection.

[0097] This embodiment supports tool-free quick locking and unlocking through the cooperation of the groove 114 of the slide rail 111 and the through hole 214 of the slider 213. The multi-position precise positioning improves shooting efficiency. Moreover, the mechanical locking structure is more vibration resistant than the traditional friction fixation, ensuring a stable connection of heavy-duty components and guaranteeing image stability.

[0098] In some embodiments, the pressing member 33 is provided with a guide groove 331, and the supporting member 32 is provided with a guide post 321. The guide post 321 is inserted in the guide groove 331. When the pressing member 33 moves, the guide post 321 is driven to move along the guide groove 331 to drive the supporting member 32 to move.

[0099] The guide groove 331 of the pressing member 33 and the guide post 321 of the supporting member 32 adopt the principle of inclined plane transmission. When the user presses or moves the pressing member 33, the guide post 321 slides along the inclined trajectory of the guide groove 331, converting the linear or rotational motion of the pressing member 33 into the translational motion of the supporting member 32. This design, through the geometric constraints of the inclined plane, precisely controls the displacement distance and direction of the supporting member 32, ensuring that the supporting member 32 can stably push the locking member 31 away from the guide groove 114 to achieve unlocking. When the pressing member 33 rebounds under the action of the first reset member 34, the guide post 321 slides in the opposite direction along the guide groove 331, driving the supporting member 32 to re-tighten against the locking member 31 to complete the locking. In addition, the tight cooperation between the guide groove 331 and the guide post 321 can also limit the movement of the supporting member 32, preventing it from deviating or jamming when subjected to force.

[0100] In this embodiment, the cooperation between the guide post 321 and the guide groove 331 forms a mechanical limit, effectively preventing the abutment 32 from shaking or misaligning during movement. Even under frequent operation or equipment vibration environment, the coordinated reliability of each component of the locking assembly 30 can be guaranteed. Moreover, the structure adopts a plug-in type fit, which makes installation and disassembly simple. If the components are worn, the guide post 321 or the pressing part 33 can be quickly replaced, reducing equipment maintenance costs and extending the service life of the handheld device 100.

[0101] Please refer to Figure 2 and Figure 5 In some embodiments, the housing 231 has a first through hole 242 communicating with the receiving cavity 233;

[0102] The third extension component 23 also includes a locking component 40, which includes:

[0103] The locking element 41 is located inside the first through hole 242. When the locking element 41 is subjected to force, it can enter the receiving cavity 233 to lock one end of the photographic auxiliary equipment.

[0104] The control member 42 is located inside the housing 231 and is in contact with the locking member 41. The control member 42 can move relative to the housing 231 to drive the locking member 41 to move.

[0105] The second reset member 43 acts on the control member 42 and is used to provide a force to reset the control member 42.

[0106] The first through-hole 242 inside the housing 231 passes through the receiving cavity 233, providing a movement channel for the locking member 41. When it is necessary to fix the photographic auxiliary equipment (such as a remote control), the user pushes the control member 42. The control member 42, through contact with the locking member 41 (such as the engagement of a ramp or slot), converts its linear movement into radial movement of the locking member 41 within the first through-hole 242, causing the locking member 41 to enter the receiving cavity 233 and lock one end of the remote control. At this time, the second reset member 43 (such as a compression spring) is compressed, storing elastic potential energy. When the user releases the control member 42, the second reset member 43 releases its elastic potential energy, pushing the control member 42 to reset, thereby causing the locking member 41 to retract into the first through-hole 242, releasing the locking state of the remote control. Through the linkage between the control member 42 and the locking member 41, the photographic auxiliary equipment can be quickly locked and released, and the precise fit between the locking member 41 and the first through-hole 242 ensures that there will be no shaking or displacement during the locking process.

[0107] This embodiment has the following advantages: First, it is secure and reliable. The locking component 41 directly locks the photography auxiliary equipment, providing stronger fixing force compared to relying solely on anti-slip textures or magnetic attraction. Even during violent shaking or inverted shooting, it can effectively prevent the equipment from falling off, ensuring the safety of the equipment during shooting. Second, it is convenient and efficient to operate. Users only need to push the control component 42 to complete the fixing and release of the equipment without additional tools or complicated operations, making it especially suitable for rapid equipment installation and disassembly in emergency shooting scenarios. Third, it has strong compatibility and adaptability. The design of the locking component 40 can adjust the length, angle, and locking force of the locking component 41 according to the size and shape of different photography auxiliary equipment, adapting to various types of remote controls and other small accessories, improving the versatility of the expansion component 20. Fourth, it ensures long-term stable operation. The elastic reset design of the second reset component 43 ensures that the control component 42 and the locking component 41 can repeatedly and reliably operate, reducing the risk of component damage caused by improper human operation, extending the service life of the locking component 40, and reducing equipment maintenance costs.

[0108] In some embodiments, the housing 231 is further provided with a second through hole 243 communicating with the receiving cavity 233, and the second through hole 243 and the first through hole 242 are arranged opposite to each other.

[0109] The third extension component 23 also includes a positioning component 50, which includes:

[0110] The positioning element 51 is located in the second through hole 243. After being subjected to force, the positioning element 51 can enter the receiving cavity 233 to lock the other end of the photography auxiliary equipment.

[0111] The third reset member 52 acts on the positioning member 51 to provide a force for the positioning member 51 to reset.

[0112] The second through hole 243 inside the housing 231 is positioned opposite to the first through hole 242, forming a symmetrical locking structure. Under the action of the third reset member 52 (such as a spring), the positioning member 51 normally protrudes from the inner wall of the receiving cavity 233. When the photographic auxiliary accessory is placed into the receiving cavity 233, one end of the positioning member 51 presses against the positioning member 51, causing it to fully retract into the second through hole 243, compressing the third reset member 52. After reaching its final position, the third reset member 52 pushes the positioning member 51 back to its original position, locking the other end of the photographic auxiliary accessory, forming a bidirectional clamping force with the locking member 41 to ensure the photographic auxiliary accessory is securely fixed. When it is necessary to remove the photographic auxiliary accessory, the locking member 41 is first released by the control member 42, and then the photographic auxiliary accessory is removed. The positioning member 51 automatically resets under the action of the third reset member 52.

[0113] The bidirectional clamping structure of this embodiment ensures that the photography auxiliary accessory is subjected to uniform force within the receiving cavity 233, effectively resisting interference from external forces at multiple angles (such as lateral swaying and longitudinal pulling), making it particularly suitable for dynamic shooting scenarios. Moreover, the elastic automatic reset function of the positioning component 51 requires no additional operation from the user; simply inserting the photography auxiliary accessory completes the positioning at one end, and it automatically releases when removed, improving ease of use.

[0114] Further, please refer to Figure 5 and Figure 7 In some embodiments, the control member 42 includes an operating part 421 and a transmission part 422. The operating part 421 is at least partially exposed on the outer surface of the housing 231, and the transmission part 422 is connected to the operating part 421 and extends to the first through hole 242.

[0115] The transmission part 422 is vertically provided with a transmission column 423, and the locking member 41 is provided with a transmission groove 411. The transmission groove 411 is an oblong groove, and its length direction is set at an acute angle with the radial movement direction of the locking member 41. The transmission column 423 is inserted into the transmission groove 411 and can slide along the groove wall. The cooperation between the transmission column 423 and the transmission groove 411 converts the linear movement of the operation part 421 into the radial movement of the locking member 41.

[0116] In this embodiment, the transmission column 423 of the control member 42 cooperates with the waist-shaped transmission groove 411 of the locking member 41, realizing motion conversion based on the principle of inclined plane transmission and trajectory constraint. When the user pushes the operation part 421 exposed outside the housing 231, the transmission part 422 connected to the operation part 421 moves synchronously in a straight line, and the vertically arranged transmission column 423 slides along the inclined trajectory of the waist-shaped transmission groove 411. Since the length direction of the transmission groove 411 forms an acute angle with the radial movement direction of the locking member 41, the linear movement of the transmission column 423 is converted into the radial movement of the locking member 41 within the first through hole 242, causing the locking member 41 to extend or retract into the receiving cavity 233. The design of the waist-shaped groove provides sliding space for the transmission column 423 and constrains its movement trajectory through the groove wall, ensuring precise and controllable action. After the operation part 421 is released, the second reset member 43 pushes it to reset, and the transmission column 423 slides in the opposite direction along the transmission groove 411, driving the locking member 41 back to its initial position.

[0117] The acute-angled transmission groove 411 allows for a large clamping force with a small operating force, improving operating efficiency. Furthermore, the length of the oblong groove limits the maximum stroke of the locking element 41, preventing excessive compression and damage to the equipment. This transmission structure occupies little space, making it suitable for implementing complex functions within a small expansion assembly 20.

Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
