[0002] Shooting support brackets include selfie sticks, multi-legged tripods, and handheld gimbals. These brackets often feature a mounting component for securing electronic devices such as mobile phones and tablets, as well as a rod connected to the mounting component. To make it easier to capture the surrounding scenery, the mounting component can rotate relative to the axis of the rod. By rotating the mounting component, the lens on the electronic device can be rotated to a specified position or rotated at a large angle to achieve panoramic shooting. In some usage scenarios, it is also necessary to prevent the mounting component from rotating relative to the axis of the rod, thereby enabling fixed-position shooting of videos or photos.
[0003] To achieve the above functions, existing technologies often incorporate a locking device on the shooting auxiliary bracket. This locking device includes a gear and a locking pin. By moving the locking pin, the pin and gear engage, thereby fixing the retaining component to the rod. Alternatively, the locking pin and gear can disengage, allowing the retaining component to rotate axially relative to the rod. However, existing locking devices have the following drawbacks: the locking pin is exposed, and its state can change under accidental impacts, altering the usability of the locking device, affecting user experience, and potentially leading to damage and malfunction.

The first connecting part is inserted into the knob and located inside the second annular part, and the limiting protrusion is located inside the limiting groove. The knob abuts against the chassis. One end of the locking part opposite to the second annular part forms a countersunk hole, and a second fastener is provided in the countersunk hole. The second fastener is used to connect the locking part and the connecting seat.
[0012] Optionally, a hinge seat is formed at the end of the mounting portion opposite to the first annular portion.
[0013] This utility model also discloses a shooting auxiliary bracket, including a rod body, a holding component and the locking module described above.

During use, the user can adjust the working state of the locking module by rotating the knob, so that the user can control the shooting auxiliary bracket according to actual needs. Specifically, the knob is threadedly connected to the mounting seat. Rotating the knob in the forward direction causes the mounting seat to move towards the locking member until the first locking surface and the second locking surface are pressed together (i.e., locked). After pressing together, without rotating the knob in the reverse direction, there is a large frictional force between the mounting seat and the locking member, thereby locking the relative rotation between the mounting seat and the locking member, and preventing them from rotating relative to each other. The knob moves, thus fixing the holding component to the rod. Similarly, rotating the knob in the opposite direction moves the mounting base away from the locking component until a gap exists between the first and second locking surfaces (i.e., unlocking). After the gap exists, the mounting base can rotate relative to the locking component, thereby allowing the holding component to rotate axially relative to the rod. The user can adjust the setting direction of the electronic device on the holding component according to actual needs. The threaded connection structure of the knob and the mounting base in the locking module provided in this embodiment has strong stability. Compared with the prior art, even if it is subjected to external force, it is not easy to change the working state of the knob. Therefore, when the locking module is applied to the shooting auxiliary bracket, the usage state of the locking module will not be arbitrarily changed due to external factors such as accidental impact, ensuring normal operation of the user during the shooting process.

Detailed Implementation
[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] This utility model embodiment provides a locking module 100, such as Figures 1 to 5 As shown, the device includes a connecting base 10, a knob 20, and a mounting base 40. The knob 20 is rotatably inserted into the connecting base 10. A locking element 30 is provided inside the knob 20 and is connected to the connecting base 10. A first locking surface 311 is formed on the locking element 30. One end of the mounting base 40 is inserted into the side of the knob 20 away from the connecting base 10 and is threadedly connected to the knob 20. A second locking surface 411 is formed inside the mounting base 40. Rotating the knob 20 can cause the mounting base 40 to move closer to or further away from the locking element 30, so that the first locking surface 311 and the second locking surface 411 are locked or unlocked.
[0025] In this embodiment, the locking module 100 includes a connecting seat 10, a knob 20, and a mounting seat 40. The connecting seat 10 is used to connect with the rod body 70, and the mounting seat 40 is used to mount the holding component 80. During use, the user can adjust the working state of the locking module 100 by rotating the knob 20, so that the user can control the shooting auxiliary support according to actual needs. Specifically, the knob 20 is threadedly connected to the mounting seat 40. Rotating the knob 20 in the forward direction causes the mounting seat 40 to move toward the locking member 30 until the first locking surface 311 and the second locking surface 411 are pressed together (i.e., locked). After pressing together, without rotating the knob 20 in the reverse direction, there is a large frictional force between the mounting seat 40 and the locking member 30, thereby locking the relative rotation between the mounting seat 40 and the locking member 30, preventing relative rotation between them, thus fixing the holding component 80. On the rod 70; similarly, rotating the knob 20 in the opposite direction causes the mounting base 40 to move away from the locking member 30 until there is a gap between the first locking surface 311 and the second locking surface 411 (i.e., unlocking). After the gap is there, the mounting base 40 can rotate relative to the locking member 30, thereby causing the holding assembly 80 to rotate axially relative to the rod 70. The user can adjust the setting direction of the electronic device on the holding assembly 80 according to actual needs. The threaded connection structure of the knob 20 and the mounting base 40 in the locking module 100 provided in this embodiment has strong stability. Compared with the prior art, even if it is subjected to external force collision, it is not easy to change the working state of the knob 20. Therefore, when the locking module 100 is applied to the shooting auxiliary bracket, the usage state of the locking module 100 will not be arbitrarily changed due to external factors such as accidental impact, ensuring the normal operation of the user during the shooting process.
[0026] Reference Figure 3 In the figure, the X direction is the axial direction of rod 70.
[0027] As a preferred embodiment, refer to Figure 3 and Figure 4 The first locking surface 311 has a first wave structure, and the second locking surface 411 has a second wave structure. When the first locking surface 311 and the second locking surface 411 are locked, the first wave structure and the second wave structure are interlocked.
[0028] The interlocking of the first and second wave structures significantly improves the locking reliability of the locking module 100. During locking, it provides greater friction and engagement force, preventing relative rotation or displacement of the locking module 100 under external force. During shooting, whether it's slight shaking or a large impact, the first locking surface 311 and the second locking surface 411 ensure that the retaining component 80 remains fixed to the rod 70, stabilizing the electronic device's position and guaranteeing clear and stable footage. This avoids shooting failures due to insecure locking, further enhancing the usability of the locking module 100 in this embodiment.
[0029] As a preferred embodiment, refer to Figures 1 to 4 The knob 20 has a first mounting groove 201 formed on the side near the mounting base 40, and an internal thread 211 is formed in the side wall of the first mounting groove 201; the mounting base 40 includes a mounting part 410 and a first annular part 420 connected to each other, the first annular part 420 is inserted into the first mounting groove 201, and an external thread 421 is formed on the outer ring of the first annular part 420, and the external thread 421 and the internal thread 211 are threadedly connected; the second locking surface 411 is located on the top wall of the first annular part 420, and the locking member 30 has one end of the first locking surface 311 located in the first annular part 420.
[0030] The mounting base 40 has a first annular portion 420 that inserts into the first mounting groove 201 of the knob 20 and is connected by internal threads 211 and external threads 421. This allows the mounting base 40 to smoothly move closer to or further away from the locking member 30 when the knob 20 is rotated, without any shaking or jamming. This precise structural fit ensures the normal operation of the locking module 100, making locking and unlocking operations smoother and improving the user experience. Simultaneously, this threaded fit increases the structural strength between the connecting base 10 and the knob 20, maintaining a stable connection that will not loosen due to external forces, alter its usage, or even detach and become damaged. This ensures the overall stability and operational stability of the locking module 100, thereby guaranteeing the normal use of the shooting auxiliary support.
[0031] As a preferred embodiment, refer to Figures 1 to 4 The locking member 30 includes a locking part 310 and a second annular part 320 connected to each other. The first locking surface 311 is located at one end of the locking part 310 away from the second annular part 320. The locking part 310 is disposed inside the first annular part 320. The second annular part 320 is connected to one end of the connecting seat 10 into the knob 20.
[0032] The locking member 30 is connected to the connecting seat 10 through the second annular part 320, which makes the installation of the locking member 30 inside the knob 20 more stable. During the rotation of the knob 20, the locking member 30 always maintains a stable position, ensuring that the first locking surface 311 can accurately cooperate with the second locking surface 411 to achieve stable locking and unlocking functions.
[0033] As a preferred embodiment, refer to Figures 1 to 4 A limiting member 50 is provided at one end of the first annular portion 420 away from the mounting portion 410. An annular limiting platform 301 is formed between the locking portion 310 and the second annular portion 320. When the first locking surface 311 and the second locking surface 411 are unlocked, the limiting member 50 abuts against the limiting platform.
[0034] The design of the limiting component 50 and the annular limiting platform 301 improves the accuracy of the locking module 100. Specifically, after unlocking, the limiting component 50 and the annular limiting platform 301 prevent the mounting base 40 from moving further away from the knob 30, thus avoiding separation between the mounting base 40 and the knob 20, which would cause the shooting auxiliary bracket to malfunction. Therefore, the design of the limiting component 50 improves the user's convenience and experience.
[0035] As a preferred embodiment, refer to Figure 1 and Figure 2 The end of the first annular portion 420 is formed with a snap-fit groove 422, and the limiting member 50 is formed with a snap-fit portion 510. The snap-fit portion 510 snaps into the snap-fit groove 422, and the first annular portion 420 and the limiting member 50 are connected by a first fastener 610.
[0036] The above details the connection method between the limiting member 50 and the first annular portion 420. By snapping the snap-fit portion 510 into the snap-fit groove 422, the limiting member 50 and the first annular portion 420 can be quickly installed and initially positioned. During the production process, workers can quickly insert the snap-fit portion 510 into the snap-fit groove 422 of the first annular portion 420. The first fastener 610 further enhances the connection between the limiting member 50 and the first annular portion 420, ensuring that the limiting member 50 will not loosen or fall off during operation, thereby ensuring the stability of the locking module 100 in use.
[0037] In this embodiment, the first fastener 610 may be a screw.
[0038] As a preferred embodiment, refer to Figures 1 to 4 The connecting seat 10 includes a first connecting part 110, a base 120, and a second connecting part 130 connected in sequence. One end of the first connecting part 110 forms a limiting groove 1101. The inner wall of the second annular part 320 is provided with a limiting protrusion 321. The first connecting part 110 is inserted into the knob 20 and located inside the second annular part 320. The limiting protrusion 321 is located inside the limiting groove 1101. The knob 20 abuts against the base 120. The locking part 310 has a countersunk hole 302 at one end away from the second annular part 320. A second fastener 620 is provided inside the countersunk hole 302. The second fastener 620 is used to connect the locking member 30 and the connecting seat 10.
[0039] This embodiment provides a detailed description of the structure of the connecting seat 10 and the connection method between the locking member 30 and the mounting seat 40. Specifically, the first connecting part 110 and the chassis 120 provide stable mounting support for the locking member 30 and the knob 20, respectively. The first connecting part 110 is inserted into the knob 20 and cooperates with the second annular part 320. Under the action of the limiting protrusion 321 located in the limiting groove 1101, the first connecting part 110 and the locking member 30 are relatively fixed. When the knob 20 is rotated, the stability of the locking member 30 is ensured. The locking member 30 and the connecting seat 10 are connected by the second fastener 620, which realizes the reliable fixing of the locking member 30. This ensures that the first locking surface 311 is always in a stable position to accurately cooperate with the second locking surface 411, ensuring the locking effect of the locking module 100 and providing stable support for shooting.
[0040] In this embodiment, the second fastener 620 may be a screw.
[0041] As a preferred embodiment, refer to Figure 1 and Figure 2 A hinge seat 412 is formed at the end of the mounting part 410 that is away from the first annular part 420.
[0042] The hinge seat 412 allows the mounting base 40 to be connected to other components via a hinge. For example, in a shooting auxiliary bracket, the mounting base 40 can be connected to the holding component 80 via the hinge seat 412, allowing the holding component 80 to adjust the tilt angle within a certain range to meet the user's shooting needs and achieve a more flexible shooting method.
[0043] In this embodiment, the hinge connection between the hinge seat 412 and the retaining component 80 can adopt an existing structure, which will not be described in detail here.
[0044] This application also discloses a shooting auxiliary support device, referring to... Figure 5 The device includes a rod 70, a holding component 80, and a locking module 100 as described in the previous embodiment. A connecting seat 10 is connected to the rod 70 at the end opposite to the mounting seat 40. The holding component 80 is located at the end of the mounting seat 40 opposite to the connecting seat 10 and is used to hold the electronic device. When using the shooting auxiliary bracket, the user holds the rod 70 and can control the holding component 80 by adjusting the locking module 100, thereby adjusting the electronic device to meet the user's needs.
[0045] The shooting support bracket has the same structure and beneficial effects as the locking module 100 in the foregoing embodiments. The structure and beneficial effects of the locking module 100 have been described in detail in the foregoing embodiments and will not be repeated here.
[0046] In this embodiment, the retaining component 80 can adopt an existing structure, and no specific limitation is made here.
[0047] As a preferred embodiment, refer to Figure 5 The rod body 70 includes a hollow tube 710, a telescopic rod 720 disposed inside the hollow tube 710, and a plurality of support feet 730 disposed on the outer periphery of the hollow tube 710. The connecting seat 10 is connected to the telescopic rod 720. When the telescopic rod 720 is in the retracted state, the locking module 100 and the holding assembly 80 can be retracted into the hollow tube 710. The support feet 730 are hinged to the hollow tube 710 so that the support feet 730 can switch between the extended state and the retracted state.
[0048] In this embodiment, when using the shooting auxiliary bracket, the user can adjust the telescopic rod 720 to adjust the electronic device fixed on the holding component 80 according to actual needs. Simultaneously, when the support foot 730 is in the extended state, the shooting auxiliary bracket can be fixed to the ground or other shooting platforms, improving user convenience. When the shooting auxiliary bracket is not in use, the user can adjust the telescopic rod 720 to the retracted state to fold the locking module 100 and the holding component 80 into the hollow tube 710, and simultaneously adjust the support foot 730 to the retracted state, thereby reducing the overall size of the shooting auxiliary bracket and improving its portability, thus enhancing the user experience.
