Description

Technical Field

[0001] This utility model relates to the field of photographic devices, and in particular to a support leg for a photographic support device and a photographic support device using the support leg. Background Technology

[0002] Tripods are commonly used support equipment in photography, videography, and surveying. They provide stable support by adjusting the height or adapting to terrain through telescopic legs. The locking and unlocking mechanism of its legs is a core design feature that directly affects operational efficiency and user experience.

[0003] In related technologies, tripod leg adjustment relies on independent locking mechanisms for each section, such as knob-type, lever-type, or snap-on types. Knob-type legs are secured by rotating and pressing the leg tube; lever-type legs are secured by flipping and clamping; and snap-on types use springs to lock the leg tubes into holes. Unlocking is done by reversing the operation, allowing the leg tubes to slide freely to adjust the length.

[0004] However, the tripod leg adjustment methods in the aforementioned technologies are cumbersome, with low efficiency due to section-by-section adjustments, and are particularly inconvenient when switching between scenes quickly, resulting in poor operational convenience. Utility Model Content

[0020] The adapter is sleeved in the middle of the bearing member and threadedly connected to the locking sleeve member;

[0021] The driving mechanism drives the second branch pipe fitting to slide relative to the first branch pipe fitting, so that the middle support member drives the abutment part to move to abut against or move away from the clamp part.

[0047] The solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0048] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0049] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0050] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0051] This application applies to photographic support devices such as tripods, which typically include a mounting device for connecting external photographic equipment and legs attached to the mounting device for supporting the mounting device on the ground.

[0052] Reference Figure 1 and Figure 2 To improve the ease of operation of the legs of a photography support device, this application proposes a leg for a photography support device, comprising:

[0053] A number of pipe components 1 are nested together in sequence, and a locking structure 2 is provided between any two adjacent pipe components;

[0054] The drive mechanism 3 is connected to each locking structure 2. The drive mechanism 3 is used to drive each locking structure 2 to configure each adjacent two tube components 1 into a relatively fixed state or a relatively sliding state.

[0055] In this embodiment, this application proposes a leg design for a photographic support device. The core of this design lies in using a single drive mechanism 3 to uniformly control multiple locking structures 2, enabling the switching between a number of sequentially nested tubular components 1 (i.e., the telescopic segments of the leg) in a relatively fixed state and a relatively sliding state. The drive mechanism 3 connects to each locking structure 2 via a transmission mechanism, translating the user's operation into the action of the locking structure 2, thereby synchronously adjusting the locking or unlocking state of all tubular components. This design abandons the traditional method of locking each section independently, utilizing a centralized transmission mechanism to improve operational convenience.

[0056] The support leg is composed of several tubular components connected in sequence. A locking structure 2 is provided between adjacent tubular components, and a drive mechanism 3 is connected to each locking structure 2. The user can operate the drive mechanism 3 (which may be a rotary handle, a pressing device, etc., exemplified here only). The drive mechanism 3 transmits the action to each locking structure 2 through a transmission method (such as thread, hydraulic pressure, or linkage rod, exemplified here only). Each locking structure 2 applies a force to the two adjacent tubular components connected to it, thereby fixing all adjacent tubular components in a relatively fixed, non-sliding state, thus locking the entire length of the support leg. To unlock, the user reverses the operation of the drive mechanism 3, the locking structure 2 releases its force, and the two adjacent tubular components connected to the locking structure 2 return to a relatively sliding state, allowing the user to freely adjust the length of the support leg. Because the drive mechanism 3 transmits power uniformly, all locking structures 2 operate simultaneously, ensuring the synchronous locking or unlocking of multiple tubular components.

[0057] By setting the legs of the photography support device with the above structure, the following beneficial effects are achieved:

[0058] Highly convenient to operate, all locking structures 2 are controlled by a single drive mechanism 3, allowing users to lock or unlock the legs with a single operation, significantly reducing adjustment time. It can quickly switch between fixed and sliding states, making it particularly suitable for photography scenarios requiring frequent height adjustments, greatly enhancing the user experience.

[0059] In summary, this application achieves centralized control of the multi-section tube components of the tripod legs through the transmission cooperation between the drive mechanism 3 and the locking structure 2. Its operation is simplified so that the user can simultaneously lock or unlock the tripod by operating the drive mechanism 3, significantly improving operational efficiency, stability, and practicality, and solving the pain point of cumbersome adjustments in traditional tripods.

[0060] Reference Figures 1 to 4In some embodiments, the plurality of sequentially connected pipe components 1 proposed in the embodiments of this application include at least a first pipe component 11, a second pipe component 12 slidably disposed within the first pipe component 11, and a third pipe component 13 slidably disposed within the second pipe component 12;

[0061] The locking structure 2 includes a first locking mechanism 21 and a second locking mechanism 22. The first locking mechanism 21 is used to configure the first tube member 11 and the second tube member 12 in a relatively fixed state or a relatively sliding state. The second locking mechanism 22 is used to configure the second tube member 12 and the third tube member 13 in a relatively fixed state or a relatively sliding state.

[0062] In this embodiment, the support legs of the photographic support device are composed of several tubular components 1 that are sequentially fitted together, including at least a first tubular component 11, a second tubular component 12, and a third tubular component 13. The second tubular component 12 is slidably fitted inside the first tubular component 11, and the third tubular component 13 is slidably fitted inside the second tubular component 12. The locking structure 2 is divided into a first locking mechanism 21 and a second locking mechanism 22, which are responsible for controlling the relative states (fixed or sliding) between the first tubular component 11 and the second tubular component 12, and between the second tubular component 12 and the third tubular component 13, respectively. The driving mechanism 3 is connected to the first locking mechanism 21 and the second locking mechanism 22 via a transmission, driving them to move in unison to achieve overall adjustment of the support legs. In some embodiments, the third tubular component 13 can also be a foot tube for supporting the ground.

[0063] The user can operate the drive mechanism 3 (e.g., a rotary handle or a pressing device), which transmits the action to the first locking mechanism 21 and the second locking mechanism 22 via a transmission system (possibly threaded, linked, or hydraulic). The first locking mechanism 21 is driven, applying a force to fix the first tube member 11 and the second tube member 12 in a relatively non-slip state. Simultaneously, the second locking mechanism 22 applies a similar force, fixing the second tube member 12 and the third tube member 13 in a relatively non-slip state. The two locking mechanisms operate synchronously, locking the entire support leg to a set length.

[0064] The working principle of this embodiment is to synchronously drive the first locking mechanism 21 and the second locking mechanism 22 through the drive mechanism 3, thereby controlling the state switching of the three-stage sleeve components (first pipe component 11, second pipe component 12, and third pipe component 13). The operation is manifested as a single operation driving the synchronous locking or unlocking of the two-stage locking.

[0065] Reference Figures 1 to 5 In some embodiments, the first locking mechanism 21 proposed in this application includes:

[0066] Pipe clamp member 211, sleeved on the second pipe member 12, has a retractable clamp opening 2110;

[0067] The locking member 212 is sleeved on the first tube member 11 and is connected to the drive mechanism 3. The locking member 212 has a supporting part 2120 that cooperates with the clamp opening 2110.

[0068] The drive mechanism 3 is used to drive the locking member 212 to move so that the abutment part 2120 abuts against or moves away from the clamp opening part 2110, so as to configure the first pipe member 11 and the second pipe member 12 in a relatively fixed state or a relatively sliding state.

[0069] In this embodiment, the first locking mechanism 21 locks or unlocks the first pipe member 11 and the second pipe member 12 through the cooperation of the pipe clamp member 211 and the locking member 212. The pipe clamp member 211 is sleeved on the second pipe member 12 and has a retractable clamp opening 2110, which can clamp or loosen the second pipe member 12 by external force. The locking member 212 is sleeved on the first pipe member 11 and is connected to the drive mechanism 3 through a transmission. The abutment part 2120 on the locking member 212 cooperates with the clamp opening 2110. The drive mechanism 3 drives the locking member 212 to move, so that the abutment part 2120 abuts against or moves away from the clamp opening 2110, thereby controlling the contraction or loosening state of the pipe clamp member 211, and thus fixing or unlocking the first pipe member 11 and the second pipe member 12. The working principle is based on the synergistic effect of mechanical transmission and extrusion deformation.

[0070] In the initial state, the clamp member 211 is fitted onto the second pipe member 12, and the clamp opening 2110 is in an uncontracted state; the locking member 212 is fitted onto the first pipe member 11, and the abutment part 2120 is close to the clamp opening 2110 but no pressure is applied.

[0071] The user can operate the drive mechanism 3 (e.g., rotate or push), which moves the clamp member 212 in a specific direction via transmission (e.g., thread or linkage). The abutting portion 2120 of the clamp member 212 gradually approaches and abuts against the clamp opening portion 2110, applying external force to cause the clamp opening portion 2110 to contract. After the clamp opening portion 2110 contracts, it squeezes the second tube member 12, increasing the friction or mechanical clamping force between it and the first tube member 11, thereby fixing the first tube member 11 and the second tube member 12 in a relatively non-slip state.

[0072] This application achieves the following effects by setting the first locking mechanism 21 of the above structure:

[0073] The cooperation between the supporting part 2120 and the clamping part 2110 enables efficient fixing of the second pipe component 12 through simple movement, resulting in rapid operation. The structure is simple: it adopts a combination design of the clamping component 211 and the locking component 212, resulting in fewer parts and direct transmission.

[0074] Reference Figure 4 and Figure 5 In some embodiments, the locking member 212 proposed in this application includes:

[0075] The locking sleeve member 2121 is sleeved on the pipe clamp member 211, and a first space is formed between the locking sleeve member 2121 and the clamp opening 2110, and a second space is formed between the locking sleeve member 2121 and the first pipe member 11, and the first space is connected to the second space.

[0076] The locking member 212 is disposed in the second space, and the driving mechanism 3 is used to drive the abutting part 2120 of the locking member 212 to extend into or away from the first space to abut or away from the clamp opening part 2110, so as to configure the first tube member 11 and the second tube member 12 in a relatively fixed state or a relatively sliding state.

[0077] In this embodiment, the locking sleeve member 2121 is fitted onto the clamp member 211, forming a first space between itself and the clamp opening 2110 of the clamp member 211, and a second space between itself and the first pipe member 11, with the first space and the second space communicating. The clamp opening 2110 is retractable, and the locking sleeve member 212 is at least partially located within the second space. Its supporting portion 2120 can be controlled by the driving mechanism 3 to extend into or away from the first space to abut or move away from the clamp opening 2110. When the supporting portion 2120 extends into the first space and abuts the clamp opening 2110, the clamp member 211 contracts and squeezes the second pipe member 12, thereby fixing the first pipe member 11 and the second pipe member 12 relatively. When the supporting portion 2120 moves away from the clamp opening 2110, the clamp opening 2110 releases the second pipe member 12, and the first pipe member 11 and the second pipe member 12 are released from their relatively fixed state.

[0078] In the initial state, the locking member 2121 is fitted over the clamp member 211, and the holding part 2120 has not yet abutted against the clamp opening 2110, so the clamp member 211 is in a relaxed state. The user can operate the drive mechanism 3 (e.g., rotate or push), and the drive mechanism 3 moves the clamp member 212 through transmission (e.g., thread or connecting rod). The holding part 2120 of the clamp member 212 extends into the first space, gradually approaching and abutting against the clamp opening 2110. The clamp opening 2110 is compressed and contracts, squeezing the second pipe member 12, so that it generates sufficient friction or clamping force between it and the first pipe member 11. At this time, the first pipe member 11 and the second pipe member 12 are configured in a relatively fixed state.

[0079] The working principle of this embodiment is that the driving mechanism 3 controls the movement of the abutment part 2120 of the locking member 212 between the first space and the second space, abutting or moving away from the clamp opening part 2110 to adjust the contraction state of the pipe clamp member 211. The working process is manifested as the spatial movement driving the clamp opening to contract or relax, realizing the locking and unlocking of each pipe member of the support leg of this application.

[0080] Please continue to refer to Figure 4 and Figure 5 In some embodiments, the inner wall of the locking sleeve member 2121 proposed in this application embodiment has internal threads; the first pipe member 11 includes a first branch pipe member 111 and a second branch pipe member 112, the second branch pipe member 112 is slidably disposed within the first branch pipe member 111 and is drively connected to the drive mechanism 3, and at least a portion of the second branch pipe member 112 is exposed outside the first branch pipe member 111; the locking clamp member 212 includes:

[0081] The middle support member 2122 has one end located between the locking sleeve member 2121 and the first branch pipe member 111, and is sleeved on the first branch pipe member 111. The middle part of the middle support member 2122 is located between the second branch pipe member 112 and the locking sleeve member 2121. The other end of the middle support member 2122 is provided with a supporting part 2120, which is located between the second pipe member 12 and the locking sleeve member 2121.

[0082] The adapter 2123 is sleeved in the middle of the bearing 2122 and threadedly connected to the locking sleeve 2121;

[0083] Among them, the driving mechanism 3 drives the second branch pipe 112 to slide relative to the first branch pipe 111, so that the middle support 2122 drives the abutment part 2120 to move to abut or move away from the clamp part 2110.

[0084] In this embodiment, the first pipe component 11 consists of a first branch pipe component 111 and a second branch pipe component 112. The second branch pipe component 112 is slidably disposed within the first branch pipe component 111 and is connected to the driving mechanism 3. The locking component 212 includes a central support 2122 and a transition component 2123. The central support 2122 is sleeved on the first branch pipe component 111, and its abutment portion 2120 is located between the second pipe component 12 and the locking sleeve component 2121. The transition component 2123 is internally threadedly connected to the locking sleeve component 2121. The driving mechanism 3 drives the second branch pipe component 112 to slide, thereby moving the central support 2122 and causing the abutment portion 2120 to abut against or move away from the clamping opening portion 2110 of the pipe clamp component 211, thereby controlling the contraction state of the clamping opening portion 2110, and ultimately achieving relative fixation or sliding between the first pipe component 11 and the second pipe component 12. The working principle is based on the sliding motion being converted into the displacement of the supporting part 2120 through the thread transmission, which indirectly adjusts the squeezing effect of the clamping part 2110.

[0085] The locking sleeve component 2121 is sleeved on the pipe clamp component 211, and its inner wall has internal threads; the second branch pipe component 112 is sleeved inside the first branch pipe component 111, and the second branch pipe component 112 is partially exposed and connected to the drive mechanism 3; the middle support component 2122 is sleeved on the first branch pipe component 111, one end of which is located between the locking sleeve component 2121 and the first branch pipe component 111, and the middle part is threadedly connected to the locking sleeve component 2121 through the adapter 2123. The abutting part 2120 is located between the second pipe component 12 and the locking sleeve component 2121, and has not yet abutted the clamp opening part 2110.

[0086] The user can operate the drive mechanism 3 (e.g., rotate or push) to drive the second branch pipe fitting 112 to slide relative to the first branch pipe fitting 111. The sliding of the second branch pipe fitting 112 causes the central support member 2122 to move as a whole. Since the adapter 2123 is internally threadedly connected to the locking sleeve member 2121, the movement of the central support member 2122 is constrained by the threaded guidance of the adapter 2123 to the locking sleeve member 2121. The abutting portion 2120 of the central support member 2122 gradually approaches and abuts the clamping portion 2110 along the axial direction of the first pipe member 11, applying pressure to cause the clamping portion 2110 to contract. After the clamping portion 2110 contracts, it squeezes the second pipe member 12, fixing the first pipe member 11 and the second pipe member 12 in a relatively non-sliding state.

[0087] In this embodiment, the second pipe component 112 is driven to slide by the drive mechanism 3. Through the threaded transmission of the bearing component 2122 and the adapter component 2123, the motion is converted into the contact or retraction of the abutment part 2120 against the clamp part 2110, thereby controlling the state of the first pipe component 11 and the second pipe component 12. The working process is manifested as the coordinated action of sliding drive, threaded guidance and clamp contraction, which achieves a precise, efficient and stable locking function, providing an optimized mechanical solution for the adjustment of the support legs of the photography support device.

[0088] Please continue to refer to Figure 4 and Figure 5 In some embodiments, the locking member 212 proposed in this application further includes:

[0089] The abutment member 2124 is threadedly connected to the middle support member 2122 and is located between the pipe clamp member 211 and the middle support member 2122. The abutment member 2124 is provided with an abutment part 2120, which is engaged with the wedge surface of the clamp opening part 2110.

[0090] In this embodiment, the abutment member 2124 is rotatably connected to the intermediate support member 2122 via a threaded connection, located between the pipe clamp member 211 and the intermediate support member 2122. It has an abutment portion 2120, which engages with the clamp opening portion 2110 of the pipe clamp member 211 via a wedge-shaped surface. The driving mechanism 3 drives the second branch pipe member 112 to slide, causing the intermediate support member 2122 to move. Furthermore, the rotation of the abutment member 2124 causes the wedge-shaped surface of the abutment portion 2120 to abut against or move away from the wedge-shaped surface of the clamp opening portion 2110, controlling the contraction state of the clamp opening portion 2110. This achieves relative fixation or sliding between the first pipe member 11 and the second pipe member 12. The working principle is based on the combined transmission of sliding motion through rotation and wedge-shaped surface compression, enhancing the accuracy and force of the locking.

[0091] It is understood that the abutment 2124 may be separately configured from the middle support 2122 as described in this embodiment, or it may be integrated with the middle support 2122 as in some embodiments, and no limitation is made here.

[0093] The first mounting component 51 is located inside the first branch pipe fitting 111;

[0094] The first bolt 52 has one end rotatably mounted on the first mounting member 51;

[0095] The second mounting part 53 is located inside the second branch pipe 112, and the second mounting part 53 is threadedly connected to the other end of the first bolt 52.

[0096] The transmission rod 54 is connected to the drive mechanism 3 at one end and to the first bolt 52 at the other end. The transmission rod 54 is used to drive the drive mechanism 3 to drive the first bolt 52 to move, so that the second mounting member 53 drives the second branch pipe member 112 to slide relative to the first branch pipe member 111, so that the middle support member 2122 drives the abutment part 2120 to abut against or move away from the clamp part 2110.

[0097] In this embodiment, a transmission mechanism 5 is added to the legs of the photographic support device to transmit the action of the drive mechanism 3 to the first locking mechanism 21, thereby locking or unlocking the first pipe member 11 and the second pipe member 12. The transmission mechanism 5 includes a first mounting member 51 (located on the first branch pipe member 111), a first bolt 52 (one end rotatably connected to the first mounting member 51, and the other end threadedly connected to the second mounting member 53), a second mounting member 53 (located on the second branch pipe member 112), and a transmission rod 54 (connecting the drive mechanism 3 and the first bolt 52). The drive mechanism 3 drives the first bolt 52 to rotate through the transmission rod 54, and the threaded action causes the second mounting member 53 to slide relative to the first branch pipe member 111, thereby pushing the middle support member 2122 to move, so that the abutment part 2120 abuts against or moves away from the clamping part 2110, controlling the contraction state of the clamping part 2110. The working principle is based on the conversion of rotational motion into linear sliding through threaded transmission, indirectly adjusting the locking state.

[0098] This application achieves the following beneficial effects by setting the transmission mechanism 5 of the above-described structure:

[0099] Firstly, the transmission mechanism 5 converts the action of the drive mechanism 3 into the linear sliding of the second sub-pipe 112 through the transmission rod 54 and bolts, so that the user can lock or unlock with a single operation, which is highly efficient.

[0100] Secondly, the transmission mechanism 5 integrates the complex sliding motion into a single trigger of the drive mechanism 3, making the operation intuitive and convenient for users and reducing the difficulty of use.

[0101] In summary, the working principle of this embodiment is that the transmission rod 54 drives the first bolt 52 to rotate, and the threaded action causes the second branch pipe 112 to slide, thereby driving the middle support 2122 and the supporting part 2120 to adjust the contraction state of the clamp part 2110. The working process is manifested as a continuous action of rotation, threaded transmission and abutment compression, which achieves a highly efficient, precise and stable locking function, providing a reliable transmission solution for the adjustment of the support legs of the photographic support device.

[0102] Reference Figure 4 and Figure 6 In some embodiments, the second locking mechanism 22 proposed in this application has the same structure as the first locking mechanism 21; the second pipe member 12 includes a third branch pipe member 121 and a fourth branch pipe member 122, the fourth branch pipe member 122 being slidably disposed within the third branch pipe member 121, and the third pipe member being slidably disposed within the fourth branch pipe member 122; the transmission mechanism 5 further includes:

[0103] The third mounting component 55 is located on the third branch pipe fitting 121;

[0104] The second bolt 56 has one end rotatably mounted on the third mounting piece 55;

[0105] The fourth mounting component 57 is located on the fourth branch pipe 122, and the other end of the second mounting component 53 is threadedly connected to the second bolt 56;

[0106] The transmission rod 54 is sequentially inserted through the first bolt 52 and the second bolt 56 to drive the first bolt 52 and the second bolt 56 to move, so that the first locking mechanism 21 and the second locking mechanism 22 move simultaneously, so as to configure the first tube member 11 and the second tube member 12 in a relatively fixed state or a relatively sliding state, and to configure the second tube member 12 and the third tube member 13 in a relatively fixed state or a relatively sliding state.

[0107] In this embodiment, the second pipe component 12, like the first pipe component 11, is a double-layered pipe component. The locking structure 2 includes a first locking mechanism 21 and a second locking mechanism 22, wherein the structure of the second locking mechanism 22 is the same as that of the first locking mechanism 21. The first locking mechanism 21 and the second locking mechanism 22 are used to control the relative states of the first pipe component 11 and the second pipe component 12, and the second pipe component 12 and the third pipe component 13, respectively. The transmission mechanism 5 includes a first bolt 52 (connecting the first branch pipe component 111 and the second branch pipe component 112), a second bolt 56 (connecting the third branch pipe component 121 and the fourth branch pipe component 122), and a transmission rod 54 sequentially passing through the two bolts, for simultaneously driving the first locking mechanism 21 and the second locking mechanism 22. The drive mechanism 3 drives the first bolt 52 and the second bolt 56 to rotate simultaneously through the transmission rod 54. The thread action causes the second sub-pipe fitting 112 and the fourth sub-pipe fitting 122 to slide, which respectively drives the middle support 2122 and the abutment part 2120 of their respective locking mechanisms to move, so as to realize the synchronous adjustment of the contraction state of the clamp part 2110 of the two locking mechanisms, thereby realizing the unified locking or unlocking of the multi-stage pipe component 1.

[0108] In some embodiments, the first mounting member 51, the second mounting member 53, the third mounting member 55, and the fourth mounting member 57 may be bearing seats, the transmission rod 54 may be a square rod, and the first bolt 52 and the second bolt 56 are provided with square holes adapted to the square rod, so that when the transmission rod 54 rotates, it can drive the first bolt 52 and the second bolt 56 to rotate, and the first bolt 52 and the second bolt 56 drive the second mounting member 53 and the fourth mounting member 57, which are threaded to them, to move in a straight line relative to the first mounting member 51 and the third mounting member 55.

[0109] Please continue to refer to Figure 6 In some embodiments, the legs of the photographic support device proposed in this application further include a mounting structure 6 for connecting the mounting device. The mounting structure 6 is disposed at the end of the first tube member 11 away from the second tube member 12; the drive mechanism 3 includes:

[0110] Rotating component 31 is connected to transmission rod 54;

[0111] The handle 32 is connected to the rotating part 31, and is used to drive the rotating part 31 to rotate the transmission rod 54 by external force.

[0112] In this embodiment, the camera support device incorporates a mounting structure 6 and a specific drive mechanism 3 to enable foot adjustment. The mounting structure 6 is located at the end of the first tube member 11 furthest from the second tube member 12 and is used to connect to the mounting device (such as the top platform of a tripod). The drive mechanism 3 includes a rotating component 31 and a handle component 32, which can be two separate parts or an integrated unit. The rotating component 31 is rotatably mounted on the mounting structure 6 and connected to a transmission rod 54. The handle component 32 is connected to the rotating component 31 for the user to apply external force. The user operates the handle component 32 to drive the rotating component 31 to rotate, which in turn drives the transmission rod 54 to rotate. The transmission rod 54 further drives the locking mechanism (such as the bolt and the central support 2122 in the previous embodiment), ultimately controlling the locking or unlocking state between the various tube members.

[0113] Furthermore, this application proposes a photographic support device, including a mounting device and a plurality of legs of the photographic support device as described in the foregoing embodiments connected to the mounting device, wherein the mounting device is used to mount external photographic equipment.
