Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary products for electronic terminals or shooting aids, and more specifically, to a multi-legged stand and an electronic terminal support device. Background Technology

[0002] Stands are primarily used to hold and support electronic devices such as tablets and mobile phones, facilitating shooting. They are also used to support shooting aids. Currently, the market offers a wide variety of stands in terms of materials and functions. For example, multi-leg stands have emerged, where the multiple legs can be adjusted to change their opening degree.

[0003] Existing multi-leg supports generally include a support rod assembly and at least three support leg assemblies. These at least three support leg assemblies can be opened or retracted relative to the support rod assembly. In the opened state, the at least three support leg assemblies can support a support surface. In the retracted state, the support leg assemblies are retracted relative to the support rod assembly. However, in existing multi-leg supports, it is not easy for the support leg assemblies to change from a retracted state to an open state relative to the support rod assembly. Utility Model Content

[0004] One of the objectives of this utility model is to provide a multi-legged bracket to solve the problem that the support leg assembly of existing multi-legged brackets is not easy to change from a folded state to an open state.

[0005] To address the above problems, this utility model provides a multi-legged bracket, which includes a support rod assembly, a sliding sleeve assembly, at least three support leg assemblies, at least three connecting rods, and a preliminary opening component. The sliding sleeve assembly is slidably fitted onto the support rod assembly along its length. At least three support leg assemblies are rotatably connected to the sliding sleeve assembly. At least three connecting rods correspond to the at least three support leg assemblies, with one end rotatably connected to the support rod assembly and the other end rotatably connected to the corresponding support leg assembly. The at least three support leg assemblies can be opened or closed relative to the support rod assembly. In the initial state, at least three support leg assemblies remain closed to the support rod assembly. At least three of the support leg assemblies are in an open state relative to the support rod assembly, and the at least three support leg assemblies can be supported on a support surface; applying a first external action to the initial opening member can cause the initial opening member to rotate relative to the support rod assembly, the initial opening member having at least three actuating portions, each of the at least three actuating portions corresponding to at least three of the support leg assemblies; during the rotation of the initial opening member from the initial position to the second position, the actuating portions actuate the corresponding support leg assemblies to cause the at least three support leg assemblies to retract relative to the support rod assembly and become initially open relative to the support rod assembly, so as to facilitate the opening of the at least three support leg assemblies relative to the support rod assembly.

[0006] Compared with the prior art, the beneficial effect of the multi-leg bracket of the present invention is that, by installing a preliminary opening member on the support rod assembly, the preliminary opening member rotates relative to the support rod assembly, causing at least three support leg assemblies to be initially opened relative to the support rod assembly, thereby making it easier for at least three support leg assemblies to open relative to the support rod assembly, and thus facilitating the use of the multi-leg bracket.

[0007] This utility model embodiment also provides a multi-legged bracket, which includes a support rod assembly, a sliding sleeve assembly, at least three support leg assemblies, at least three connecting rods, and a preliminary opening member. The sliding sleeve assembly is slidably sleeved on the support rod assembly along its length. At least three support leg assemblies are rotatably connected to the sliding sleeve assembly. At least three connecting rods correspond to the at least three support leg assemblies, with one end rotatably connected to the support rod assembly and the other end rotatably connected to the corresponding support leg assembly. The at least three support leg assemblies can be opened or closed relative to the support rod assembly. In the initial state, the at least three support leg assemblies remain closed to the support rod assembly. With the three support leg assemblies in an open state relative to the support rod assembly, the at least three support leg assemblies can be supported on a support surface; the initial opening member is slidably mounted on the support rod assembly, and applying a second external force to the initial opening member causes the initial opening member to translate relative to the support rod assembly in a first direction; the initial opening member has at least three push portions, and the at least three push portions correspond to at least three support leg assemblies respectively; during the process of the initial opening member translating from the initial position to the third position, the push portions push the corresponding support leg assemblies to cause the at least three support leg assemblies to retract relative to the support rod assembly, thus changing the at least three support leg assemblies into an initial opening relative to the support rod assembly.

[0008] Compared with the prior art, the beneficial effect of the multi-leg bracket of the present invention is that, by installing a preliminary opening member on the support rod assembly, the preliminary opening member translates relative to the support rod assembly in a first direction, causing at least three support leg assemblies to be initially opened relative to the support rod assembly, thereby making it easier for at least three support leg assemblies to open relative to the support rod assembly, and thus facilitating the use of the multi-leg bracket.

[0009] This utility model embodiment also provides an electronic terminal support device, including a support member and the multi-leg bracket, wherein the support member is used to support the electronic terminal and the support member is installed on the support rod assembly of the multi-leg bracket.

[0010] Compared with the prior art, the beneficial effect of the electronic terminal support device of the present invention is that at least three support foot assemblies of the electronic terminal support device of the present invention are initially opened relative to the support rod assembly, so that at least three support foot assemblies are easy to open relative to the support rod assembly, thereby facilitating the use of the electronic terminal support device.

[0069] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of 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 some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0070] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0071] This utility model embodiment provides a multi-leg bracket, see reference. Figures 1-27 The multi-leg bracket includes a support rod assembly 100, a sliding sleeve assembly 200, at least three support foot assemblies 300, at least three connecting rods 400, and a preliminary opening member 500. The sliding sleeve assembly 200 is slidably sleeved on the support rod assembly 100 along its length. At least three support foot assemblies 300 are rotatably connected to the sliding sleeve assembly 200. At least three connecting rods 400 correspond to at least three support foot assemblies 300, with one end rotatably connected to the support rod assembly 100 and the other end rotatably connected to the corresponding support foot assembly 300. The at least three support foot assemblies 300 can be opened or closed relative to the support rod assembly 100. In the initial state, the at least three support foot assemblies 300 remain closed to the support rod assembly 100. When the support rod assembly 100 is in an open state, at least three support foot assemblies 300 can be supported on a support surface. Applying a first external action to the initial opening member 500 can cause the initial opening member 500 to rotate relative to the support rod assembly 100. The initial opening member 500 has at least three actuating portions 540, each corresponding to one of the at least three support foot assemblies 300. During the rotation of the initial opening member 500 from the initial position to the second position, the actuating portions 540 actuate the corresponding support foot assemblies 300 to cause the at least three support foot assemblies 300 to close relative to the support rod assembly 100 and then initially open relative to the support rod assembly 100, thereby facilitating the opening of the at least three support foot assemblies 300 relative to the support rod assembly 100. Understandably, the initial opening member 500 rotates relative to the support rod assembly 100 to initially open at least three support leg assemblies 300 relative to the support rod assembly 100, thereby making it easier for the at least three support leg assemblies 300 to open relative to the support rod assembly 100, and thus facilitating the use of the multi-leg bracket.

[0072] For example, the multi-legged stand of this utility model embodiment can be used to support electronic terminals and / or shooting aids. The electronic terminals can be mobile phones, tablets, cameras, etc., and the shooting aids can be fill lights, remote controls, cameras, etc.

[0073] For example, the support rod assembly 100 may be telescopic in its length direction, or the support rod assembly 100 may be of a fixed length; for example, the support rod assembly 100 may include multiple telescopic joints, among which a first telescopic joint is included, and the sliding sleeve assembly 200 is slidably fitted onto the first telescopic joint. The number of support foot assemblies 300 may be 3, 4, etc., and the number of connecting rods 400 may be 3, 4, etc., the same as the number of support foot assemblies 300. The sliding sleeve assembly 200, support rod assembly 100, support foot assembly 300, and corresponding connecting rods 400 constitute a planar four-bar linkage mechanism. Specifically, this planar four-bar linkage mechanism may be a crank-slider mechanism, a rocker-slider mechanism, etc. During the opening of the support foot assembly 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides relative to the support rod assembly 100; the sliding sleeve assembly 200 is at different positions on the support rod assembly 100 depending on the degree of opening of the support foot assembly 300 relative to the support rod assembly 100.

[0074] For example, with at least three support foot assemblies 300 retracted relative to the support rod assembly 100, the user can hold the at least three support foot assemblies 300. For instance, when the support rod assembly 100 supports an electronic terminal, the user can hold the at least three support components to take a selfie. In some cases, with at least three support foot assemblies 300 retracted relative to the support rod assembly 100, the connecting rod 400 retracts into the support rod assembly 100, and the connecting rod 400 is located between the support rod assembly 100 and the corresponding support foot assembly 300.

[0075] It should be understood that at least three support leg assemblies 300 remain in a retracted state relative to the support rod assembly 100, and at least three support leg assemblies 300 can maintain a stable retracted shape relative to the support rod assembly 100. For example, during the handling of the multi-legged support, the support leg assemblies 300 maintain a stable retracted shape relative to the support rod assembly 100, and the support leg assemblies 300 cannot spread out relative to the support rod assembly 100, for example, the support leg assemblies 300 do not spread out relative to the support rod assembly 100 due to their own weight. For example, in the retracted state, the support leg assemblies 300 are engaged with the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200, or, for example, the support leg assemblies 300 are magnetically attracted to the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200.

[0076] It should be understood that when at least three support leg assemblies 300 are open relative to the support rod assembly 100, at least three support leg assemblies 300 are initially opened or spread out relative to the support rod assembly 100. In common cases, when at least three support leg assemblies 300 are initially open relative to the support rod assembly 100, they further open, causing them to spread out relative to the support rod assembly 100, thereby allowing them to be supported on a support surface. In other less common cases, the initially open state of at least three support leg assemblies 300 relative to the support rod assembly 100 is considered a type of spread-out state, meaning that in this initially open state, at least three support leg assemblies 300 can be supported on a support surface.

[0077] In some situations, when the support foot assembly 300 is retracted into the support rod assembly 100, the support foot assembly 300 is subjected to a retracting force that keeps it retracted into the support rod assembly 100. For example, when the support foot assembly 300 is engaged with the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200, the retracting force is partly or entirely derived from the engaging force of the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200 on the support foot assembly 300; or, for example, when the support foot assembly 300 is magnetically attracted to the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200, the retracting force is partly or entirely derived from the magnetic attraction of the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200. At least three support foot assemblies 300 retract relative to the support rod assembly 100, becoming initially open relative to the support rod assembly 100. The retraction force on the support foot assemblies 300 decreases or disappears, making it easier for them to further open relative to the support rod assembly 100, thus placing them in an open state. For example, in the initially open state, because the retraction force on the support foot assemblies 300 is reduced to zero, it is easier for the user to manually pry the support foot assemblies 300 apart relative to the support rod assembly 100, or for the user to more easily slide the sliding sleeve assembly 200, thereby facilitating the opening of the support foot assemblies 300 relative to the support rod assembly 100. For example, when the support foot assembly 300 is initially opened relative to the support rod assembly 100, under the weight of the moving assembly, the support foot assembly 300 opens relative to the support rod assembly 100, the sliding sleeve assembly 200 slides toward the bottom end of the support rod assembly 100, and the connecting rod 400 opens relative to the support rod assembly 100, thereby making the support foot assembly 300 in an open state relative to the support rod assembly 100. The moving assembly includes the support foot assembly 300, the connecting rod 400, and the sliding sleeve assembly 200.

[0078] In other cases, at least three support leg assemblies 300 retract relative to the support rod assembly 100, which is changed to at least three support leg assemblies 300 initially opening relative to the support rod assembly 100. The retraction force on the support leg assemblies 300 remains unchanged, but because the support leg assemblies 300 are initially opened relative to the support rod assembly 100, it is also convenient for the user to further pry the support leg assemblies 300 relative to the support rod assembly 100 with their hands or external tools, thereby facilitating the opening of the support leg assemblies 300 relative to the support rod assembly 100.

[0079] Specifically, the support surface can be the ground, a tabletop, etc., and can be a flat or curved surface, or a horizontal or inclined surface.

[0080] In some implementations, the rotatability of the initial opening member 500 relative to the support rod assembly 100 means that during the movement of the initial opening member 500 relative to the support rod assembly 100, at least one component of the motion of the initial opening member 500 is its rotational motion relative to the support rod assembly 100. For example, the initial opening member 500 may be rotatably connected to the support rod assembly 100 via a revolute joint, allowing the user to directly manipulate the initial opening member 500 to rotate relative to the support rod assembly 100. Alternatively, the initial opening member 500 may both translate and rotate relative to the support rod assembly 100.

[0081] Understandably, applying a first external action to the initial opening member 500 causes the initial opening member 500 to rotate relative to the support rod assembly 100, thereby opening the support foot assembly 300 relative to the support rod assembly 100. For example, when the initial opening member 500 can only rotate relative to the support rod assembly 100, the first external action is a rotational torque about the rotation axis of the initial opening member 500. Applying a rotational torque to the initial opening member 500 (e.g., a user manually turning the initial opening member 500) causes the initial opening member 500 to rotate relative to the support rod assembly 100, thereby initially opening the support foot assembly 300 relative to the support rod assembly 100. When the initial opening member 500 is both translatable and rotatable relative to the support rod assembly 100, the first external action is a pair of forces acting on the initial opening member 500 along a first direction, applying a force to the initial opening member 500 to cause it to translate relative to the support rod assembly 100 along the first direction and thus rotate relative to the support rod assembly 100. Alternatively, the first external action is a rotational torque about the rotation axis of the initial opening member 500, applying a rotational torque to the initial opening member 500 to cause it to rotate relative to the support rod assembly 100.

[0082] In some implementations, the initial opening member 500 is restricted to the support rod assembly 100 such that the initial opening member 500 cannot exceed the initial position, or the initial opening member 500 exceeds the second position. For example, in the initial position, the initial opening member 500 directly or indirectly abuts against the support rod assembly 100; or, in the second position, the initial opening member 500 directly or indirectly abuts against the support rod assembly 100.

[0083] For example only, during the process of at least three support foot assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the angle of rotation of the support foot assembly 300 relative to the support rod assembly 100 is greater than or equal to 0.5°, such as 0.5°, 1°, 2°, 3°, etc.

[0084] It should be understood that the initial position of the preliminary opening component 500 can refer to a specific position or a range of positions; the second position of the preliminary opening component 500 can refer to a specific position or a range of positions, for example, any position that allows the support leg assembly 300 to be in a preliminary opening state can be the second position of the preliminary opening component 500.

[0085] In some implementations of the embodiments of this utility model, reference is made to Figure 6 , Figure 18 During the rotation of the initial opening member 500 relative to the support rod assembly 100, the initial opening member 500 can also translate relative to the support rod assembly 100 along a first direction. During the application of a first external force to the initial opening member 500, the initial opening member 500 translates relative to the support rod assembly 100 along the first direction and rotates relative to the support rod assembly 100. The first external force includes a force acting on the initial opening member 500 along the first direction, and / or, the first external force includes a rotational torque acting on the initial opening member 500 about its rotation axis 501. It is understood that the initial opening member 500 can be rotated relative to the support rod assembly 100 by applying the first external force, thereby opening the support leg assembly 300 relative to the support rod assembly 100. Furthermore, there can be multiple methods of the first external force, thus facilitating the use of this multi-leg bracket.

[0086] In some cases, the first external action includes a force along a first direction (all or part of the first external action is a force along the first direction, for example, a component of the first external action is a force along the first direction), which is a pushing force directed toward the support rod assembly 100, which can be achieved by the user pressing the initial opening member 500 by hand or by the initial opening member 500 striking the support surface; the force can also be a pulling force away from the support rod assembly 100, for example, the user can pull the initial opening member 500. Understandably, the force must overcome the resistance experienced by the initial opening member 500 (which includes the frictional resistance between the initial opening member 500 and the support rod assembly 100), causing the initial opening member 500 to translate relative to the support rod assembly 100 in the first direction, and causing the initial opening member 500 to rotate relative to the support rod assembly 100.

[0087] In other cases, the first external action includes a rotational torque acting on the initial opening member 500 and about its rotation axis 501 (all or part of the first external action is a rotational torque about the rotation axis 501, for example, a component of the first external action is a rotational torque about the rotation axis 501). Alternatively, a rotational torque may be applied to the initial opening member 500 (e.g., a user moves the initial opening member 500 by hand or an external tool), causing the initial opening member 500 to rotate relative to the support rod assembly 100, thereby causing the support foot assembly 300 to initially open relative to the support rod assembly 100.

[0088] In some implementations, the initial opening member 500 is connected to the support rod assembly 100 via a cam pair. During the movement of the initial opening member 500 relative to the support rod assembly 100, the initial opening member 500 both translates and rotates relative to the support rod assembly 100. Specifically, the support rod assembly 100 has a connecting protrusion, and the initial opening member 500 has a connecting groove (or, the support rod assembly 100 has a connecting groove, and the initial opening member 500 has a connecting protrusion). The connecting protrusion and the connecting groove cooperate to form a cam pair. The connecting protrusion slides or rolls within the connecting groove, causing the initial opening member 500 to both translate and rotate relative to the support rod assembly 100. Specifically, the connecting groove and the connecting protrusion are cylindrical cam mechanisms; for example, the connecting groove extends along a helical line. The first external action overcomes the resistance experienced by the initial opening member 500 (this resistance includes the frictional resistance between the connecting protrusion and the connecting groove), causing the connecting protrusion to slide or roll along the connecting groove.

[0089] For example, the first direction is along the length of the support rod assembly 100. For instance, the initial opening member 500 is installed at the bottom end of the support rod assembly 100, and the first direction is the direction from the bottom end of the support rod assembly 100 to its top end.

[0090] Furthermore, during the process of the initial opening member 500 translating relative to the support rod assembly 100 in the first direction and rotating relative to the support rod assembly 100, the translation of the initial opening member 500 relative to the support rod assembly 100 in the first direction plays an auxiliary role in the initial opening of the support foot assembly 300.

[0091] In some implementations of the embodiments of this utility model, reference is made to Figure 6 , Figure 18The initial opening member 500 is provided with a first thread 510, and the support rod assembly 100 is provided with a second thread 121. The first thread 510 and the second thread 121 mate. The rotation axis 501 of the initial opening member 500 is coaxial with the central axis of the first thread 510. During the application of a first external action to the initial opening member 500, the initial opening member 500 rotates relative to the support rod assembly 100 about the rotation axis, and the initial opening member 500 translates relative to the support rod assembly 100 in a first direction along the rotation axis. The first external action includes a force acting on the initial opening member 500 along the rotation axis 501, and / or, the first external action includes a rotational torque acting on the initial opening member 500 about the rotation axis 501. It is understood that the first thread 510 and the second thread 121 facilitate the manufacture of the initial opening member 500 and the support rod assembly 100, and also facilitate the installation of the initial opening member 500 onto the support rod assembly 100. The first direction is along the rotation axis 501.

[0092] Understandably, the initial opening component 500 is helically connected to the support rod assembly 100. The initial opening component 500 and the support rod assembly 100 are helically connected through a helical pair. During the helical movement of the initial opening component 500 relative to the support rod assembly 100, the first external force overcomes the resistance experienced by the initial opening component 500 (the frictional resistance between the first thread 510 and the second thread 121). The initial opening component 500 both translates and rotates relative to the support rod assembly 100.

[0093] For example, the first thread 510 and the second thread 121 are rectangular threads, or the first thread 510 and the second thread 121 are triangular threads, etc. The structure of the first thread 510 and the second thread 121 allows at least one first external action to drive the initial opening member 500; for example, the helix angle of the first thread 510 is 30.6°. The first thread 510 is an external thread and the second thread 121 is an internal thread, or the first thread 510 is an internal thread and the second thread 121 is an external thread.

[0094] In some cases, the first external action includes a force along the rotation axis 501 (part or all of the first external action is a force along the rotation axis 501, for example, a component of the first external action is a force along the rotation axis 501), which is a pushing force directed toward the support rod assembly 100. The user can press the initial opening member 500 by hand, or the initial opening member 500 can be pressed by striking the support surface. The force can also be a pulling force away from the support rod assembly 100, for example, the user can pull the initial opening member 500. In other cases, the first external action includes a rotational torque acting on the initial opening member 500 and about its rotation axis 501 (part or all of the first external action is a rotational torque about the rotation axis 501, for example, the component of the first external action is a rotational torque about the rotation axis 501). Alternatively, a rotational torque may be applied to the initial opening member 500 (e.g., a user moves the initial opening member 500 by hand or an external tool), causing the initial opening member 500 to rotate relative to the support rod assembly 100, thereby causing the support foot assembly 300 to initially open relative to the support rod assembly 100.

[0095] In some implementations of the embodiments of this utility model, reference is made to Figure 6 , Figure 18 , Figure 21 The multi-leg bracket also includes a return spring 610. The return spring 610 acts on the initial opening member 500. When at least three support leg assemblies 300 are open relative to the support rod assembly 100, the return spring 610 returns the initial opening member 500 from the second position to the initial position. The return spring 610 prevents the initial opening member 500 from obstructing the retraction of the support leg assemblies 300 relative to the support rod assembly 100. Specifically, it prevents the actuating portion of the initial opening member from obstructing the retraction of the support leg assemblies relative to the support rod assembly.

[0096] Understandably, during the movement of the initial opening member 500 relative to the support rod assembly 100 caused by the first external action, the resistance experienced by the initial opening member 500 also includes the elastic force exerted on the initial opening member 500 by the return spring 610.

[0097] For example, when at least three support foot assemblies 300 are initially opened relative to the support rod assembly 100, the return spring 610 causes the initially opened member 500 to return from the second position to the initial position.

[0098] For example, the return spring 610 can be a column spring, a tower spring, a torsion spring, etc. In some cases, the return spring 610 is a column spring or a tower spring, and the function of the return spring 610 on the initial opening member 500 is the force acting on the initial opening member 500 along the rotation axis 501. This force is the tension or push force of the return spring 610 on the initial opening member 500. In other cases, the return spring 610 is a torsion spring, and the function of the return spring 610 on the initial opening member 500 is the rotational torque acting on the initial opening member 500 about the rotation axis 501.

[0099] In some implementations of the embodiments of this utility model, reference is made to Figure 6 , Figure 18 , Figure 21 The initial opening component 500 has a mounting post 520, a first thread 510 on the mounting post 520, a support rod assembly 100 has a mounting cavity 101, the mounting post 520 is mounted in the mounting cavity 101, a second thread 121 is provided on the cavity wall of the mounting cavity 101, the mounting post 520 has a receiving cavity 502, the receiving cavity 502 is connected to one end of the mounting post 520, at least three actuating parts 540 are all connected to the mounting post 520; the mounting post 520 has a first abutting wall 503, the first abutting wall 503 is located in the receiving cavity. 502, the support rod assembly 100 has a second abutment wall 102 located in the mounting cavity 101; the return spring 610 is a columnar spring or a tower-shaped spring, with its first end housed in the receiving cavity 502, the first end of the return spring 610 abutting against the first abutment wall 503, and its second end abutting against the second abutment wall 102; during the rotation of the initial opening member 500 from the initial position to the second position, the mounting post 520 moves toward the second abutment wall 102, and the return spring 610 is compressed. Understandably, the mounting post 520 is mounted in the mounting cavity 101, and the first end of the return spring 610 is housed in the receiving cavity 502, such that the return spring 610 is at least partially housed in the receiving cavity 502, making the overall structure of the multi-leg bracket compact.

[0100] For example, a columnar spring can be a cylindrical spring, a square columnar spring, a polygonal columnar spring, etc., and a tower-shaped spring can be a conical spring, a frustum-shaped spring, a polygonal tower-shaped spring, etc. The force exerted by the return spring 610 on the initial opening member 500 is a force acting on the initial opening member 500 along the rotation axis 501, which is the thrust of the return spring 610 on the initial opening member 500. It should be understood that the first external action includes a thrust force acting on the initial opening member 500 along the rotation axis 501, and / or, the first external action includes a rotational torque acting on the initial opening member 500 about the rotation axis 501.

[0101] Understandably, the first end of the return spring is housed in the receiving cavity, which restricts the return spring to the initial opening part, making it difficult for the return spring to bend or fall out of its working position during extension and retraction.

[0102] Understandably, the return spring is a columnar spring or a tower-shaped spring, which makes the return spring easy to compress and ensures that it does not obstruct the movement of the initial opening component.

[0103] It should be understood that the first thread 510 is an external thread and the second thread 121 is an internal thread.

[0104] Obviously, during the process of the initial opening member 500 rotating from the initial position to the second position, the initial opening member 500 translates along the rotation axis 501 and rotates around the rotation axis 501.

[0105] In some implementations, the mounting post 520 has a first end face 504, and a receiving cavity 502 communicates with the first end face 504. When the initial opening member 500 is in the second position, the first end face 504 abuts against the second abutting wall 102, and the return spring 610 is housed in the receiving cavity 502. The abutment between the first end face 504 and the second abutting wall 102 allows the initial opening member 500 to easily rotate to the second position, thereby initially opening the support leg assembly 300. In this case, the abutment between the first end face 504 and the second abutting wall 102 also restricts the initial opening member 500's installation on the support rod assembly 100; the position of the initial opening member 500 relative to the support rod assembly 100 cannot exceed its second position.

[0106] In other implementations, the mounting post 520 has a first end face 504, and the receiving cavity 502 communicates with the first end face 504. When the initial opening member 500 is in the second position, the first end face 504 is spaced from the second abutment wall 102, and the return spring 610 is mostly housed in the receiving cavity 502.

[0107] Some implementations of the embodiments of this utility model are described below. Figure 6 , Figure 18 , Figure 21The initial opening component 500 also includes a connecting post 530, which is connected to the mounting post 520. One end of the connecting post 530 is housed in the receiving cavity 502, and a return spring 610 is sleeved on the connecting post 530. The support rod assembly 100 has a retaining part 122 with a through hole 103 through which the connecting post 530 passes. The retaining part 122 has a second abutment wall 102. When the initial opening component is in the initial position, the retaining part is used to retain the connecting post. The multi-leg bracket also includes a first fastener 620. The first fastener 620 is securely connected to the connecting post 530. The first head 621 of the first fastener 620 and the mounting post of the initial opening member 500 are located on opposite sides of the holding part 122. During the process of the initial opening member 500 returning from the second position to the initial position, the return spring 610 acts on the initial opening member 500, and the first head 621 of the first fastener 620 moves toward the holding part 122. When the initial opening member 500 is in the initial position, the first head 621 of the first fastener 620 abuts against the holding part 122 to hold the connecting post. It can be understood that the holding part holds the connecting post, specifically the first head 621 of the first fastener 620 abuts against the holding part 122, so that the initial opening member 500 is mounted on the support rod assembly 100 in a restricted manner, preventing the initial opening member 500 from disengaging from the support rod assembly 100 under the action of the return spring 610. The reset spring 610 is sleeved on the connecting post 530, which prevents the reset spring 610 from coming out of the receiving cavity 502, making it less likely for the reset spring to bend or come out of its working position during the extension and retraction process, and also making the structure of the multi-leg bracket compact.

[0108] Specifically, the first fastener 620 can be a threaded part or a riveted part (such as a screw, rivet, etc.), and the first fastener 620 also facilitates the installation of the initial opening part 500.

[0109] In some implementations, when the initial opening member is in the initial position, the connecting post directly or indirectly abuts against the blocking part.

[0110] Understandably, one end of the connecting column is housed in the receiving cavity, the first abutting wall 503 is located in the receiving cavity 502, and the first end of the return spring is housed in the receiving cavity, making the structure of the multi-leg bracket compact.

[0111] In some implementations of the embodiments of this utility model, reference is made to Figure 6 , Figure 18 , Figure 21The support rod assembly 100 includes a support rod body 110 and a mounting member 120. The mounting member 120 is mounted on the support rod body 110, and each connecting rod 400 is rotatably connected to the mounting member 120. A mounting cavity 101 is provided in the mounting member 120, a second thread 121 is provided in the mounting member 120, and the mounting member 120 has a second abutment wall 102. Understandably, the support rod assembly 100 includes the support rod body 110 and the mounting member 120 to facilitate the assembly of the support rod assembly 100. The mounting member 120 is used both for rotatably connecting the connecting rods 400 and for mounting the initial opening member 500, making the structure of the multi-legged bracket compact.

[0112] In some implementations of the embodiments of this utility model, reference is made to Figure 6 , Figure 18 , Figure 21 The initial opening component 500 also includes a connecting post 530, which is connected to the mounting post 520. One end of the connecting post 530 is housed in the receiving cavity 502, and a return spring 610 is sleeved on the connecting post 530. The mounting component 120 has a retaining portion 122 with a through hole 103 through which the connecting post 530 passes. The retaining portion 122 has a second abutment wall 102. The multi-leg bracket also includes a first fastener 620, which is connected to the connecting post 530. The fastener is securely connected, with the first head 621 of the first fastener 620 and the mounting post of the initial opening member 500 located on opposite sides of the retaining portion 122. During the process of the initial opening member 500 returning from the second position to the initial position, the return spring 610 acts on the initial opening member 500, causing the first head 621 of the first fastener 620 to move towards the retaining portion 122. When the initial opening member 500 is in the initial position, the first head 621 of the first fastener 620 abuts against the retaining portion 122. This abutment between the first head 621 of the first fastener 620 and the retaining portion 122 prevents the initial opening member 500 from disengaging from the support rod assembly 100. Furthermore, the abutment between the first head 621 of the first fastener 620 and the retaining portion 122, along with the return spring 610, ensures that the initial opening member 500 returns to its initial position, preventing the initial opening member 500 from affecting the retraction of the support foot assembly 300 into the support rod assembly 100.

[0113] In some implementations of the embodiments of this utility model, reference is made to Figure 6 , Figure 18 , Figure 21The mounting component 120 is installed at the bottom end of the support rod body 110. When at least three support foot assemblies 300 are opened to their maximum open state relative to the sliding sleeve assembly 200, the sliding sleeve assembly 200 abuts against the mounting component 120. The mounting component 120 includes a mounting portion 123 and a mounting protrusion 124 connected to the mounting portion 123. Each connecting rod 400 is rotatably connected to the mounting protrusion 124 of the mounting component 120. The mounting cavity 101 communicates with the mounting portion 123. The support rod body 110 has a mounting hole 104 communicating with its bottom end. The mounting portion 123 is inserted into the mounting hole 104. The support rod assembly 100 also includes a second fastener 130, which passes through the support rod body 110 and is fastened to the mounting portion 123. The sliding sleeve assembly 200 has a sliding cavity 201 that is slidably adapted to the support rod assembly 100. The inner wall of the support rod assembly 110 is provided with a sliding strip 210, which extends along the sliding direction of the sliding cavity 201. The outer wall of the support rod body 110 is provided with a sliding groove 105, which is adapted to the sliding strip 210. During the sliding of the sliding sleeve assembly 200 along the length of the support rod assembly 100, the sliding strip 210 slides in the sliding groove 105. The second fastener 130 includes a second head 131 and a second rod portion 132 connected to the second head 131. The second head 131 is accommodated in the sliding groove 105, and the second rod portion 132 passes through the support rod body 110 and is fastened to the mounting portion 123. When the sliding sleeve assembly 200 and the support rod assembly 100 are in contact, the second head 131 is accommodated in the sliding cavity 201 and is located between the bottom end of the sliding strip 210 and the bottom end of the sliding sleeve assembly 200. Understandably, the sliding sleeve assembly 200 abuts against the mounting part 120 to prevent the multi-leg bracket from having an excessively large opening angle, which would cause the support leg assembly 300 and the connecting rod 400 to deform, thus preventing damage to the multi-leg bracket during use.

[0114] Understandably, the second fastener 130 securely connects the mounting part 123 to the support rod body 110, and the mounting part 123 is not easily detached from the support rod body 110. The second fastener 130 can be a threaded fastener, a riveted fastener, etc.

[0115] Understandably, the cooperation between the sliding bar 210 and the sliding groove 105 makes the sliding sleeve assembly 200 slide more stably relative to the support rod assembly 100. By housing the second head 131 within the sliding groove 105, the possibility of the second head 131 scratching the user is reduced. Furthermore, the sliding groove 105 serves both to cooperate with the sliding bar 210 and to house the second head 131, resulting in a compact structure for the support rod assembly 100. When the sliding sleeve assembly 200 is in contact with the support rod assembly 100, the second head 131 is located between the bottom end of the sliding bar 210 and the bottom end of the sliding sleeve assembly 200, preventing the second head 131 from obstructing the sliding of the sliding sleeve assembly 200. Moreover, the second head 131 is housed within the sliding cavity 201, further preventing the second head 131 from scratching the user's hand. For example, there are two sliding bars 210, located on opposite sides of the sliding cavity 201; there are two sliding grooves 105, located on opposite sides of the support rod body 110; and there are two second fasteners 130, with their second heads 131 respectively housed within the two sliding grooves 105. Understandably, both the sliding bars 210 and the sliding grooves 105 extend along the sliding direction of the sliding sleeve assembly 200.

[0116] For example, when the sliding sleeve assembly 200 is in contact with the mounting member 120, the sliding sleeve assembly 200 is in contact with the mounting protrusion 124.

[0117] For example, the sliding sleeve assembly 200 has at least three first rotating portions 202, and the support foot assembly 300 has second rotating portions 311. The second rotating portions 311 of the at least three support foot assemblies 300 are rotatably connected to the corresponding first rotating portions 202. The first rotating portion 202 is a shaft and the second rotating portion 311 is a hole, or the first rotating portion 202 is a hole and the second rotating portion 311 is a shaft. For example, the support rod assembly 100 has a third rotating portion 106, and the connecting rod 400 has a fourth rotating portion 410. The third rotating portion 106 and the fourth rotating portion 410 are rotatably engaged. The third rotating portion 106 is a hole and the fourth rotating portion 410 is a shaft, or the third rotating portion 106 is a shaft and the fourth rotating portion 410 is a hole. For example, the support foot assembly 300 has a fifth rotating part 301, and the connecting rod 400 has a sixth rotating part 420. The fifth rotating part 301 and the sixth rotating part 420 are rotatably engaged. The fifth rotating part 301 is a hole and the sixth rotating part 420 is a shaft, or the fifth rotating part 301 is a shaft and the sixth rotating part 420 is a hole.

[0118] For example, the mounting member 120 includes a first mounting sub-member 120a and a second mounting sub-member 120b, the second mounting sub-member 120b being mounted on the first mounting sub-member 120a, a second thread 121 being provided on the first mounting sub-member 120a, the first mounting sub-member 120a including a mounting portion 123, the first mounting sub-member 120a also including a portion of a mounting protrusion 124, the second mounting sub-member 120b including a portion of the mounting protrusion 124, and the second mounting sub-member 120b being mounted on the first mounting sub-member 120a to form the mounting protrusion 124. When the sliding sleeve assembly 200 abuts against the mounting member 120, the sliding sleeve assembly 200 abuts against the first mounting sub-member 120a. Specifically, the first mounting sub-component 120a is mounted to the second mounting sub-component 120b via a third fastener 125, which can be a threaded component, a riveted component, etc.; the third rotating part 106 is a hole, and the first mounting sub-component 120a and the second mounting sub-component 120b are combined to form the third rotating part 106. The advantage of this arrangement is that it facilitates the rotatable mounting of the connecting rod 400 to the support rod assembly 100. For example, one way to install the connecting rod 400 is to place the connecting rod 400 between the first mounting sub-component 120a and the second mounting sub-component 120b, and then mount the second mounting sub-component 120b to the first mounting sub-component 120a via the third fastener 125.

[0119] Specifically, a second thread 121 is provided in the mounting portion 123, the mounting cavity 101 communicates with the mounting portion 123, and a retaining portion 122 is provided in the mounting portion 123. A second fastener 130 passes through the support rod body 110 and is fastened to the first mounting sub-part 120a.

[0120] In some implementations of the embodiments of this utility model, reference is made to Figure 4 , Figure 6 , Figure 18 When the support leg assembly 300 is retracted into the support rod assembly 100, the support leg assembly 300 is subjected to a retracting force that keeps it retracted into the support rod assembly 100. During the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 and then initially opening relative to the support rod assembly 100, the retracting force weakens or decreases to zero. Understandably, the weakening or zeroing of the retracting force on the support leg assembly 300 makes it easier for the support leg assembly 300 to further open, facilitating the open state of the support leg assembly 300 relative to the support rod assembly 100.

[0121] Reference Figure 6When the support foot assembly 300 is retracted into the support rod assembly 100, the support foot assembly 300 and the connecting rod 400 are magnetically attracted to each other. During the process of at least three support foot assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the attractive force of the connecting rod 400 on the support foot assembly 300 weakens or becomes zero. Understandably, the weakened attractive force of the connecting rod 400 on the support foot assembly 300 makes it easier for the support foot assembly 300 to open further, facilitating the open state of the support foot assembly 300 relative to the support rod assembly 100.

[0122] For example, the support foot assembly 300 includes a support foot body 310 and a magnetic member 320. The magnetic member 320 is detachably mounted to the support body. When the support foot assembly 300 is retracted into the support rod assembly 100, the magnetic member 320 magnetically attracts the connecting rod 400. For example, the magnetic member 320 is made of a permanent magnet material, such as AlNiCo permanent magnet alloys, IronChromiumCo permanent magnet alloys, permanent magnet ferrites, rare earth permanent magnet materials, and composite permanent magnet materials. For example, a small portion of the connecting rod 400 is made of a soft magnetic material, such as cast iron, silicon steel, carbon steel, alloy steel, or soft magnetic ferrites. The connecting rod 400 includes a soft magnetic body and a plating layer. The soft magnetic body is made of a soft magnetic material, and the plating layer is attached to the soft magnetic body.

[0123] In some implementations of the embodiments of this utility model, reference is made to Figure 1 The multi-legged tripod is used to support electronic terminals or shooting aids. With at least three support leg assemblies 300 retracted into the support rod assembly 100, the at least three support leg assemblies 300 can be held handheld. Understandably, the handheld nature of the at least three support leg assemblies 300 facilitates the user's use of the multi-legged tripod; for example, a user can hold the at least three support leg assemblies 300 to take a selfie. For example, when the at least three support leg assemblies 300 are retracted into the support rod assembly 100, the at least three support leg assemblies 300 are cylindrical.

[0124] In some implementations of the embodiments of this utility model, reference is made to Figure 4With at least three support leg assemblies 300 retracted relative to the support rod assembly 100, each actuating part 540 is located between two adjacent support leg assemblies 300. Understandably, the multi-leg bracket, with each actuating part 540 located between two adjacent support leg assemblies 300, has a compact structure and occupies a small volume in the retracted state. Specifically, each support leg assembly 300 has a contact surface 302. During the rotation of the initial opening member 500 from the initial position to the second position, the actuating part 540 actuates the contact surface 302 of the corresponding support leg assembly 300. The contact surfaces 302 of two adjacent support leg assemblies 300 are intersected. With at least three support leg assemblies 300 retracted relative to the support rod assembly 100, each actuating part 540 is located within the space enclosed by the contact surfaces 302 of two adjacent support leg assemblies 300.

[0125] In some implementations of the embodiments of this utility model, reference is made to Figure 1 , Figure 13 , Figure 19 During the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 and initially opening relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction. When the at least three support leg assemblies 300 are initially opened relative to the support rod assembly 100 and the second direction is along the direction of gravity, the self-weight of the moving component causes at least three support leg assemblies 300 to open relative to the support rod assembly 100. The moving component includes the sliding sleeve assembly 200, at least three support leg assemblies 300, and at least three connecting rods 400. Understandably, the self-weight of the moving component causes at least three support leg assemblies 300 to "automatically" open, thereby facilitating the use of the multi-leg bracket.

[0126] Clearly, the second direction is along the length of the support rod assembly 100. During the initial opening of at least three support foot assemblies 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction, the support foot assembly 300 rotates relative to the sliding sleeve assembly 200, the support foot assembly 300 initially opens relative to the support rod assembly 100, the connecting rod 400 rotates relative to the support rod assembly 100, and the connecting rod 400 rotates relative to the support foot assembly 300.

[0127] Since the second direction is along the direction of gravity, the self-weight of the moving component includes at least the self-weight of the sliding sleeve assembly 200. During the initial opening of at least three support leg assemblies 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction, causing its center of gravity to drop. In some cases, the self-weight of the moving component also includes the self-weight of the support leg assembly 300 and the connecting rod 400. During the initial opening of at least three support leg assemblies 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction, causing its center of gravity to drop. One end of the support leg assembly 300 slides with the sliding sleeve assembly 200, while the other end opens relative to the support rod assembly 100, causing its center of gravity to drop. The connecting rod 400 retracts relative to the support rod assembly 100, becoming open relative to the support rod assembly 100, causing its center of gravity to drop.

[0128] In some implementations of this utility model, the first external action includes a rotational torque acting on the initial opening member 500 and about its rotation axis 501. The initial opening member 500 has a rotation adjustment part, and the user can apply a rotational torque about the rotation axis 501 to the rotation adjustment part by hand to rotate the initial opening member 500 from the initial position to the second position. It is understood that the rotation adjustment part facilitates the user's manual adjustment of the initial opening member 500, thereby facilitating the use of the multi-legged stand. In this case, the first external action includes the rotational torque applied by the user to the rotation adjustment part. The rotation adjustment part can be of any shape that the user can adjust by hand; it can be columnar, sheet-like, etc.

[0129] In some implementations of the embodiments of this utility model, reference is made to Figure 4 , Figure 8The support foot assembly 300 comprises three units, the actuating part 540 comprises three units, and the rotation adjustment part includes three adjustment plates 550. These three adjustment plates 550 are centrally symmetrical about the rotation axis 501 of the initial opening member 500. Each adjustment plate 550 is connected to a corresponding actuating part 540. Two adjacent adjustment plates 550 form a force application space 505, where the user's three fingers can be placed to facilitate manual adjustment of the rotation adjustment part. Understandably, the user's three fingers can be placed in the force application spaces 505 to adjust the rotation adjustment part, thus facilitating the use of the multi-legged stand. Each of the three fingers can apply rotational torque to the rotation adjustment part. For example, by placing the three fingers in the three force application spaces 505 and then rotating the arm, the user can apply force to each of the three adjustment plates 550. More specifically, the user's three fingers are the thumb, index finger, and middle finger. By applying rotational torque to the initial opening member 500 using three fingers, it is easier to rotate the initial opening member 500, thereby facilitating the use of the multi-leg bracket. In other cases, the rotation adjustment part includes one adjustment plate 550, two adjustment plates 550, four adjustment plates 550, etc.

[0130] In some implementations of the embodiments of this utility model, reference is made to Figure 6 The initial opening member 500 has a pressure-applying portion 560. A first external action includes a force acting on the initial opening member 500 along a first direction. Applying pressure to the pressure-applying portion 560 along the first direction causes the initial opening member 500 to translate relative to the support rod assembly 100 in the first direction and to rotate relative to the support rod assembly 100. (The user applies pressure to the pressure-applying portion 560, allowing the user to press and rotate the initial opening member 500 relative to the support rod assembly 100, thereby initially opening the support leg assembly 300 relative to the support rod assembly 100, facilitating the use of the multi-leg bracket. For example, the user presses the pressure-applying portion 560 with their hand, or the user strikes the support surface to apply pressure to the initial opening member 500. For example, at least three adjusting tabs 550 are connected to the pressure-applying portion 560, and at least three actuating portions 540 are connected to the pressure-applying portion 560; this arrangement enhances the structural strength of the initial opening member 500.)

[0131] In some implementations of the embodiments of this utility model, reference is made to Figure 6The initial opening member 500 is installed at the bottom end of the support rod assembly 100. With at least three support leg assemblies 300 retracted relative to the support rod assembly 100, the pressure-applying portion 560 protrudes from the bottom end of the support leg assemblies 300. When the at least three support leg assemblies 300 are retracted relative to the support rod assembly 100, the pressure-applying portion 560 of the initial opening member 500 impacts the support surface, causing the support surface to apply pressure to the pressure-applying portion 560 along a first direction, resulting in the initial opening member 500 translating and rotating relative to the support rod assembly 100. It can be understood that the initial opening member 500 is located at the bottom end of the support rod assembly 100, and the pressure-applying portion 560 protrudes from the bottom end of the support leg assemblies 300, facilitating the impact of the pressure-applying portion 560 of the initial opening member 500 onto the support surface. By impacting the support surface, pressure on the pressure-applying portion 560 is more easily achieved.

[0132] In some implementations of the embodiments of this utility model, reference is made to Figure 1 , Figure 6 , Figure 13 , Figure 18 , Figure 19 The initial opening member 500 has a pressure-applying portion 560. A first external action includes a force acting on the initial opening member 500 along a first direction. Pressure is applied to the pressure-applying portion 560 along the first direction, causing the initial opening member 500 to translate relative to the support rod assembly 100 and rotate relative to the support rod assembly 100. During the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 to initially open relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along a second direction. When at least three support leg assemblies 300 retract relative to the support rod assembly 100 and the second direction is along the direction of gravity, the pressure-applying portion 560 of the initial opening member 500 impacts the support surface along the second direction. As the support rod assembly 100 translates along a first direction and the initial opening member 500 rotates relative to the support rod assembly 100, at least three support leg assemblies 300 initially open relative to the support rod assembly 100. After the pressure portion of the initial opening member impacts the support surface along a second direction (which is also along the direction of gravity), causing the at least three support leg assemblies to initially open relative to the support rod assembly, the self-weight and inertia of the moving component cause at least three support leg assemblies 300 to open relative to the support rod assembly 100. The moving component includes a sliding sleeve assembly 200, at least three support leg assemblies 300, and at least three connecting rods 400. The inertia of the moving component includes the inertia of maintaining movement along the second direction during the impact of the pressure portion 560 on the support surface. It is understood that the self-weight and inertia of the moving component cause at least three support leg assemblies 300 to open "automatically," thereby facilitating the use of the multi-leg bracket.

[0133] Understandably, when the pressure part 560 of the initial opening component 500 impacts the support surface in the second direction, the moving component still maintains its inertia of moving in the second direction.

[0134] Since the second direction is along the direction of gravity, the self-weight of the moving component includes at least the self-weight of the sliding sleeve assembly 200. Furthermore, the multi-leg bracket impacts the support surface along the second direction, so the inertia of the moving component includes at least the inertia of the sliding sleeve assembly 200. During the initial opening and subsequent opening of at least three support leg assemblies 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction under inertia, causing the center of gravity of the sliding sleeve assembly 200 to drop, thereby causing at least three of the support leg assemblies to open relative to the support rod assembly. In some cases, the self-weight of the moving component also includes the self-weight of the support leg assembly and the self-weight of the connecting rod. The inertia of the moving component also includes the inertia of the support leg assembly and the inertia of the connecting rod. During the process of at least three support leg assemblies 300 initially opening relative to the support rod assembly 100, the moving component slides the sliding sleeve assembly 200 along the second direction under its own weight and inertia, and the center of gravity of the sliding sleeve assembly 200 drops. Under its own weight and inertia, one end of the support leg assembly 300 slides with the sliding sleeve assembly 200, and the other end opens relative to the support rod assembly 100, and the center of gravity of the support leg assembly 300 drops. Under its own weight and inertia, the connecting rod 400 closes relative to the support rod assembly 100 and opens relative to the support rod assembly 100, and the center of gravity of the connecting rod 400 drops, thereby causing at least three of the support leg assemblies to open relative to the support rod assembly.

[0135] In some implementations of the embodiments of this utility model, reference is made to Figure 6 , Figure 18 The support foot assembly 300 has a contact surface 302. During the translational movement of the initial opening member 500 along the first direction, the actuating part 540 contacts the contact surface 302 of the corresponding support foot assembly 300. The angle between the outer normal direction of the contact surface 302 and the first direction is greater than 90° to facilitate the initial opening of the support foot assembly 300 relative to the support rod assembly 100. The angle between the outer normal direction of the contact surface 302 and the first direction is greater than 90°. During the translational movement of the initial opening member 500 along the first direction, the actuating part 540 pushes against the contact surface 302, thereby facilitating the opening of the support foot assembly 300 relative to the support rod assembly 100. For example, the contact surface 302 is a plane or a curved surface.

[0136] Specifically, at least three support foot assemblies 300 are opened to their maximum open state relative to the support rod assembly 100, and at least three support foot assemblies 300 are supported on the support surface, with the contact surface 302 in contact with the support surface. More specifically, each support foot assembly 300 includes an anti-slip pad 330 and a support foot body 310, with the anti-slip pad 330 located at the bottom end of the support foot body 310, and the contact surface 302 located on the anti-slip pad 330.

[0137] In other cases, during the translation of the initial opening member 500 along the first direction, the angle between the outer normal direction of the contact surface 302 and the first direction is 90° or less. The translation of the initial opening member 500 along the first direction does not affect the opening of the support foot assembly 300 relative to the support rod assembly 100. The rotation of the initial opening member 500 about its rotation axis 501 causes the support foot assembly 300 to open relative to the support rod assembly 100.

[0138] This utility model embodiment also provides an electronic terminal support device, see reference. Figure 28 The system includes a support member 710 and a multi-legged bracket. The support member 710 supports the electronic terminal and is mounted on a support rod assembly 100 of the multi-legged bracket. For example, the support member 710 is mounted directly or indirectly to the support rod assembly 100, such as by a connecting arm 720 mounted to the support rod assembly 100. Specifically, the support member 710 is rotatably mounted to the connecting arm 720, and the support member 710 rotates relative to the connecting arm 720 to adjust the orientation of the electronic terminal (e.g., horizontal, vertical, diagonal, etc.). More specifically, the support member 710 is rotatable around its full circumference relative to the connecting arm 720. Specifically, the connecting arm 720 is rotatably mounted on the support rod assembly 100. The connecting arm 720 rotates relative to the support rod assembly 100 to adjust the usage angle of the electronic terminal. When it is necessary to store the electronic terminal support device, the connecting arm 720 can be folded to the support rod assembly 100, or the connecting arm 720 can be folded to the support foot assembly 300 in a folded state.

[0139] For example, the support 710 can be a clamp for holding an electronic terminal. The clamp includes a clamp body and two clamping parts. The two clamping parts clamp the opposite two sides of the electronic terminal respectively. The clamp body can be elastically extended and retracted to adjust the clamping width of the clamp. The clamping parts can be stored in the clamp body.

[0140] For example, the support 710 is a suction cup for attaching an electronic terminal, such as a suction cup that can be attached to the back of the electronic terminal.

[0141] For example, the support 710 is the magnetic element 320 of the magnetic electronic terminal, and the magnetic element 320 can be an electromagnet or a permanent magnet.

[0142] For example, support 710 is a tray for supporting an electronic terminal, on which the electronic terminal is placed.

[0143] For example, the support 710 is a card holder for a card-holding electronic terminal, and the card holder is used to hold the card-holding electronic terminal.

[0144] This utility model embodiment also proposes a method of using a multi-legged bracket. The method includes: providing the aforementioned multi-legged bracket, with at least three support leg assemblies 300 of the multi-legged bracket retracting into the support rod assembly 100 of the multi-legged bracket, the initial opening member 500 of the multi-legged bracket being in an initial position, the initial opening member 500 having a rotation adjustment part, the number of support leg assemblies 300 being three, the number of actuating parts 540 being three, the rotation adjustment part including three adjusting plates 550, the three adjusting plates 550 being centrally symmetrical about the rotation axis 501 of the initial opening member 500, and the three adjusting plates 550 being respectively connected to... The corresponding three actuation parts 540 are connected, and the two adjacent adjustment pieces 550 are force application spaces 505; the user's three fingers are placed in the three force application spaces 505 respectively; the user's arm is rotated to apply a rotational torque about its rotation axis 501 to the initial opening member 500, so that the rotation adjustment part rotates about the rotation axis 501 of the initial opening member 500, so that the initial opening member 500 is rotated from the initial position to the second position, so that at least three support foot assemblies 300 are initially opened relative to the support rod assembly 100; so that at least three support foot assemblies 300 are opened relative to the support rod assembly 100.

[0145] Understandably, applying rotational torque to the initial opening member 500 using three fingers and an arm makes it easier to rotate the initial opening member 500, thus facilitating the use of the multi-leg bracket. With at least three support leg assemblies 300 initially open relative to the support rod assembly 100, there are multiple ways to open the at least three support leg assemblies 300 relative to the support rod assembly 100. For example, it is easier for the user to pry the support leg assemblies 300 apart relative to the support rod assembly 100 by hand, or it is easier for the user to slide the sliding sleeve assembly 200, thereby making the support leg assemblies 300 open relative to the support rod assembly 100.

[0146] Furthermore, during the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction. The step of opening the at least three support leg assemblies 300 relative to the support rod assembly 100 includes aligning the second direction with the direction of gravity. The weight of the moving component causes the at least three support leg assemblies 300 to open relative to the support rod assembly 100. The moving component includes the sliding sleeve assembly 200 of the multi-leg bracket, the at least three support leg assemblies 300, and the at least three connecting rods 400 of the multi-leg bracket. The multi-leg bracket can "automatically open" by utilizing the weight of the moving component, reducing manual operation by the user and thus facilitating the use of the multi-leg bracket. Obviously, the weight of the moving component is greater than the resistance force acting on the moving component.

[0147] This utility model embodiment also provides a method of using a multi-leg bracket, characterized in that the method includes: providing the above-mentioned multi-leg bracket, at least three support leg assemblies 300 of the multi-leg bracket being retracted into the support rod assembly 100 of the multi-leg bracket, the initial opening member 500 of the multi-leg bracket being in an initial position, the initial opening member 500 having a pressure application portion 560; applying pressure to the pressure application portion 560 along a first direction to cause the initial opening member 500 to translate along the first direction, so that the initial opening member 500 rotates relative to the support rod assembly 100, causing at least three support leg assemblies 300 to initially open relative to the support rod assembly 100; and opening at least three support leg assemblies 300 relative to the support rod assembly 100.

[0148] Furthermore, during the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction; the step of opening the at least three support leg assemblies 300 relative to the support rod assembly 100 includes: the second direction being along the direction of gravity, and the self-weight of the moving component causing the at least three support leg assemblies 300 to open relative to the support rod assembly 100. The moving component includes the sliding sleeve assembly 200, at least three support leg assemblies 300, and at least three connecting rods 400. Utilizing the self-weight of the moving component to "automatically open" the multi-leg bracket reduces manual operation by the user, thereby facilitating the use of the multi-leg bracket.

[0149] Furthermore, during the process of at least three support foot assemblies 300 retracting relative to the support rod assembly 100 to initially open relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction; the step of applying pressure to the pressure part 560 along the first direction to cause the initial opening member 500 to translate along the first direction includes: the pressure part 560 of the initial opening member 500 impacts the support surface along the second direction to cause the initial opening member 500 to translate relative to the support rod assembly 100 along the first direction, the second direction being along the direction of gravity;

[0150] The step of opening at least three support leg assemblies 300 relative to the support rod assembly 100 includes: the self-weight and inertia of the moving component causing the at least three support leg assemblies 300 to open relative to the support rod assembly 100. The moving component includes a sliding sleeve assembly 200 of the multi-leg bracket, at least three support leg assemblies 300, and at least three connecting rods 400 of the multi-leg bracket. The inertia of the moving component includes maintaining its inertia in the second direction during the impact of the pressure portion 560 on the support surface in the second direction. The multi-leg bracket "automatically opens" by utilizing the self-weight and inertia of the moving component, and the support leg assemblies 300 of the multi-leg bracket open faster by utilizing the self-weight and inertia of the moving component, thereby facilitating the use of the multi-leg bracket.

[0151] Reference Figures 29-55This utility model embodiment proposes a multi-legged bracket, which includes a support rod assembly 100, a sliding sleeve assembly 200, at least three support foot assemblies 300, at least three connecting rods 400, and a preliminary opening member 500. The sliding sleeve assembly 200 is slidably sleeved on the support rod assembly 100 along the length direction of the support rod assembly 100. The at least three support foot assemblies 300 are rotatably connected to the sliding sleeve assembly 200. The at least three connecting rods 400 correspond to the at least three support foot assemblies 300 respectively, with one end of the connecting rod 400 rotatably connected to the support rod assembly 100 and the other end rotatably connected to the corresponding support foot assembly 300. The at least three support foot assemblies 300 can be opened or closed relative to the support rod assembly 100. In the initial state, the at least three support foot assemblies 300 remain closed to the support rod assembly 100. With at least three support leg assemblies 300 in an open state relative to the support rod assembly 100, the at least three support leg assemblies 300 can be supported on a support surface; the initial opening member 500 is slidably mounted on the support rod assembly 100, and applying a second external action to the initial opening member 500 can cause the initial opening member 500 to translate relative to the support rod assembly 100 in a first direction. The initial opening member 500 has at least three push portions 570, and the at least three push portions 570 correspond to the at least three support leg assemblies 300 respectively; during the process of the initial opening member 500 translating from the initial position to the third position, the push portions 570 push the corresponding support leg assemblies 300 to cause the at least three support leg assemblies 300 to close relative to the support rod assembly 100 and become initially open relative to the support rod assembly 100.

[0152] Understandably, the translation of the initial opening member 500 relative to the support rod assembly 100 causes at least three support leg assemblies 300 to initially open relative to the support rod assembly 100, thereby making it easier for the at least three support leg assemblies 300 to open relative to the support rod assembly 100, and thus facilitating the use of the multi-leg bracket.

[0153] For example, the multi-legged stand of the present invention can be used to support electronic terminals and / or shooting aids. The electronic terminals can be mobile phones, tablets, cameras, etc., and the shooting aids can be fill lights, remote controls, cameras, etc.

[0154] For example, the support rod assembly 100 may be telescopic in its length direction, or the support rod assembly 100 may be of a fixed length; for example, the support rod assembly 100 may include multiple telescopic joints, among which a first telescopic joint is included, and the sliding sleeve assembly 200 is slidably fitted onto the first telescopic joint. The number of support foot assemblies 300 may be 3, 4, etc., and the number of connecting rods 400 may be 3, 4, etc., the same as the number of support foot assemblies 300. The sliding sleeve assembly 200, support rod assembly 100, support foot assembly 300, and corresponding connecting rods 400 constitute a planar four-bar linkage mechanism. Specifically, this planar four-bar linkage mechanism may be a crank-slider mechanism, a rocker-slider mechanism, etc. During the opening of the support foot assembly 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides relative to the support rod assembly 100; the sliding sleeve assembly 200 is at different positions on the support rod assembly 100 depending on the degree of opening of the support foot assembly 300 relative to the support rod assembly 100.

[0155] For example, with at least three support foot assemblies 300 retracted relative to the support rod assembly 100, the user can hold the at least three support foot assemblies 300. For instance, when the support rod assembly 100 supports an electronic terminal, the user can hold the at least three support components to take a selfie. In some cases, with at least three support foot assemblies 300 retracted relative to the support rod assembly 100, the connecting rod 400 retracts into the support rod assembly 100, and the connecting rod 400 is located between the support rod assembly 100 and the corresponding support foot assembly 300.

[0156] It should be understood that at least three support leg assemblies 300 remain in a retracted state relative to the support rod assembly 100, and at least three support leg assemblies 300 can maintain a stable retracted shape relative to the support rod assembly 100. For example, during the handling of the multi-legged support, the support leg assemblies 300 maintain a stable retracted shape relative to the support rod assembly 100, and the support leg assemblies 300 cannot spread out relative to the support rod assembly 100, for example, the support leg assemblies 300 do not spread out relative to the support rod assembly 100 due to their own weight. For example, in the retracted state, the support leg assemblies 300 are engaged with the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200, or, for example, the support leg assemblies 300 are magnetically attracted to the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200.

[0157] It should be understood that when at least three support leg assemblies 300 are open relative to the support rod assembly 100, at least three support leg assemblies 300 are initially opened or spread out relative to the support rod assembly 100. In common cases, when at least three support leg assemblies 300 are initially open relative to the support rod assembly 100, they further open, causing them to spread out relative to the support rod assembly 100, thereby allowing them to be supported on a support surface. In other less common cases, the initially open state of at least three support leg assemblies 300 relative to the support rod assembly 100 is considered a type of spread-out state, meaning that in this initially open state, at least three support leg assemblies 300 can be supported on a support surface.

[0158] In some situations, when the support foot assembly 300 is retracted into the support rod assembly 100, the support foot assembly 300 is subjected to a retracting force that keeps it retracted into the support rod assembly 100. For example, when the support foot assembly 300 is engaged with the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200, the retracting force is partly or entirely derived from the engaging force of the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200 on the support foot assembly 300; or, for example, when the support foot assembly 300 is magnetically attracted to the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200, the retracting force is partly or entirely derived from the magnetic attraction of the connecting rod 400, the support rod assembly 100, or the sliding sleeve assembly 200. At least three support foot assemblies 300 retract relative to the support rod assembly 100, becoming initially open relative to the support rod assembly 100. The retraction force on the support foot assemblies 300 decreases or disappears, making it easier for them to further open relative to the support rod assembly 100, thus placing them in an open state. For example, in the initially open state, because the retraction force on the support foot assemblies 300 is reduced to zero, it is easier for the user to manually pry the support foot assemblies 300 apart relative to the support rod assembly 100, or for the user to more easily slide the sliding sleeve assembly 200, thereby facilitating the opening of the support foot assemblies 300 relative to the support rod assembly 100. For example, when the support foot assembly 300 is initially opened relative to the support rod assembly 100, under the weight of the moving assembly, the support foot assembly 300 opens relative to the support rod assembly 100, the sliding sleeve assembly 200 slides toward the bottom end of the support rod assembly 100, and the connecting rod 400 opens relative to the support rod assembly 100, thereby making the support foot assembly 300 in an open state relative to the support rod assembly 100. The moving assembly includes the support foot assembly 300, the connecting rod 400, and the sliding sleeve assembly 200.

[0159] In other cases, at least three support leg assemblies 300 retract relative to the support rod assembly 100, which is changed to at least three support leg assemblies 300 initially opening relative to the support rod assembly 100. The retraction force on the support leg assemblies 300 remains unchanged, but because the support leg assemblies 300 are initially opened relative to the support rod assembly 100, it is also convenient for the user to further pry the support leg assemblies 300 relative to the support rod assembly 100 with their hands or external tools, thereby facilitating the opening of the support leg assemblies 300 relative to the support rod assembly 100.

[0160] Specifically, the support surface can be the ground, a tabletop, etc., and can be a flat or curved surface, or a horizontal or inclined surface.

[0161] In some implementation methods, refer to Figure 36 , Figure 37 Alternatively, the support rod assembly 100 may have an installation cavity 101, and the initial opening member 500 may be slidably engaged with the installation cavity 101 of the support rod assembly 100; or, the initial opening member 500 may have an installation cavity 101, and the support rod assembly 100 may be engaged with the installation cavity 101 of the initial opening member 500.

[0162] Specifically, when the initial opening member 500 slides relative to the support rod assembly 100, the second external action is to apply a force to the initial opening member 500 along the first direction, thereby applying a force to the initial opening member 500 so that the initial opening member 500 translates relative to the support rod assembly 100 along the first direction.

[0163] For example only, during the process of at least three support foot assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the angle of rotation of the support foot assembly 300 relative to the support rod assembly 100 is greater than or equal to 0.5°, such as 0.5°, 1°, 2°, 3°, etc.

[0164] It should be understood that the initial position of the preliminary opening component 500 can refer to a specific position or a range of positions; the third position of the preliminary opening component 500 can refer to a specific position or a range of positions. For example, any position that allows the support leg assembly 300 to be in a preliminary opening state can be the third position of the preliminary opening component 500.

[0165] It should be understood that the translational direction of the initial opening component 500 can be along the first direction, or the translational direction of the initial opening component 500 can be the opposite direction to the first direction.

[0166] In some implementations, the second external action includes a force acting on the initial opening member 500 along a first direction. Understandably, applying a force along the first direction to the initial opening member 500 causes it to translate from an initial position to a third position, thereby causing the pusher portion 570 to push the corresponding support foot assembly 300, causing at least three support foot assemblies 300 to retract relative to the support rod assembly 100, thus initially opening at least three support foot assemblies 300 relative to the support rod assembly 100.

[0167] It should be understood that the second external action is entirely a force acting on the initial opening member 500 and along the first direction, or a component of the second external action is a force acting on the initial opening member 500 and along the first direction. More specifically, this force is a pushing force directed towards the support rod assembly 100, which the user can achieve by pressing the initial opening member 500 by hand or by the initial opening member 500 striking the support surface. This force can also be a pulling force away from the support rod assembly 100, for example, by the user pulling the initial opening member 500. It is understood that the force must overcome the resistance experienced by the initial opening member 500 (including the frictional resistance between the initial opening member 500 and the support rod assembly 100) so that the initial opening member 500 translates relative to the support rod assembly 100 in the first direction.

[0168] For example, the first direction is along the length of the support rod assembly 100. For instance, the initial opening member 500 is installed at the bottom end of the support rod assembly 100, and the first direction is the direction from the bottom end of the support rod assembly 100 to its top end.

[0169] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The multi-leg bracket also includes a return spring 610, which acts on the initial opening member 500, causing the initial opening member 500 to return from the third position to the initial position. Understandably, the return spring 610 causes the initial opening member 500 to return to the initial position, preventing the initial opening member 500 from hindering the retraction of the support leg assembly 300 relative to the support rod assembly 100. Specifically, it prevents the push portion 570 of the initial opening member 500 from hindering the retraction of the support leg assembly 300 relative to the support rod assembly 100.

[0170] Understandably, during the movement of the initial opening member 500 relative to the support rod assembly 100 caused by the second external action, the resistance experienced by the initial opening member 500 also includes the elastic force exerted on the initial opening member 500 by the return spring 610.

[0171] For example, when at least three support foot assemblies 300 are initially opened relative to the support rod assembly 100, the return spring 610 causes the initially opened member 500 to return from the third position to the initial position.

[0172] For example, the return spring 610 can be a column spring, a tower spring, a torsion spring, etc. In some cases, the return spring 610 is a column spring or a tower spring. The function of the return spring 610 on the initial opening member 500 is to exert a force on the initial opening member 500 along its translational direction. This force is the tension or pushing force of the return spring 610 on the initial opening member 500.

[0173] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The initial opening component 500 has a mounting post 520, and the support rod assembly 100 has a mounting cavity 101. The mounting post 520 is slidably mounted in the mounting cavity 101, and at least three push parts 570 are connected to the mounting post 520. The mounting post 520 has a first abutting wall 503, and the support rod assembly 100 has a second abutting wall 102, which is located in the mounting cavity 101. The return spring 610 is a columnar spring or a tower-shaped spring. The first end of the return spring 610 abuts against the first abutting wall 503, and the second end abuts against the second abutting wall 102. During the process of the initial opening component 500 translating from the initial position to the third position, the mounting post 520 moves toward the second abutting wall 102, and the return spring 610 is compressed. Understandably, the mounting post 520 is slidably mounted in the mounting cavity 101, and the return spring 610 is a columnar spring or a tower-shaped spring, which makes the return spring 610 easy to compress, so that the return spring 610 does not hinder the translation of the initial opening member 500.

[0174] For example, a columnar spring can be a cylindrical spring, a square columnar spring, a polygonal columnar spring, etc., and a tower-shaped spring can be a conical spring, a frustum-shaped spring, a polygonal tower-shaped spring, etc. The force exerted by the return spring 610 on the initial opening member 500 is a force acting on the initial opening member 500 along its translational direction, which is the thrust of the return spring 610 on the initial opening member 500. It should be understood that the second external action includes a thrust force acting on the initial opening member 500 along the translational direction.

[0175] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50The mounting post 520 has a receiving cavity 502, which is connected to one end of the mounting post 520. The first abutment wall 503 is located in the receiving cavity 502. The first end of the return spring 610 is received in the receiving cavity 502. Understandably, the first end of the return spring 610 is received in the receiving cavity 502, ensuring that the return spring 610 is at least partially received in the receiving cavity 502, making the overall structure of the multi-leg bracket compact. Furthermore, the first end of the return spring 610 being received in the receiving cavity 502 restricts the return spring 610 to the initial opening member 500, making it less likely for the return spring 610 to bend or displace from its operating position during extension and retraction.

[0176] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The initial opening member 500 also includes a connecting post 530 connected to the mounting post 520, and a return spring 610 sleeved on the connecting post 530. The support rod assembly 100 has a retaining part 122, which retains the connecting post 530 to prevent the initial opening member 500 from disengaging from the support rod assembly 100 when the initial opening member 500 is in the initial position. The initial opening member 500 also includes a stop member 580 mounted on the connecting post 530. When the initial opening member 500 is in the initial position, the stop member 580 abuts against the retaining part 122 to achieve the retaining part 122 retaining the connecting post 530. During the process of the initial opening member 500 returning from the third position to the initial position, the return spring 610 acts on the initial opening member 500 to cause the stop member 580 to move toward the retaining part 122. Understandably, the retaining part 122 retains the connecting post 530 of the initial opening member 500, so that the initial opening is mounted on the support rod assembly 100 in a restricted manner, preventing the initial opening member 500 from detaching from the support rod assembly 100 under the action of the return spring 610. The return spring 610 is sleeved on the connecting post 530, so that the return spring 610 is not easy to bend or detach from its working position during the extension and retraction process, and also makes the structure of the multi-leg bracket compact.

[0177] For example, the initial opening member 500 also includes a fourth fastener 590, which passes through the stop member 580 and is fastened to the connecting post 530. The fourth fastener 590 is used to install the stop member 580 onto the connecting post 530.

[0178] For example, the connecting post 530 is slidably mounted on the support rod assembly, which has a through hole 103. The connecting post 530 is slidably mounted on the through hole 103 of the support rod assembly, so that the initial opening member is slidably mounted on the support rod assembly.

[0179] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 When the initial opening part 500 is in the initial position, the connecting post 530 directly or indirectly abuts against the retaining part 122.

[0180] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The mounting post 520 has a receiving cavity 502, which is connected to one end of the mounting post 520. A first abutment wall 503 is located in the receiving cavity 502. The first end of the return spring 610 is received in the receiving cavity 502. One end of the connecting post 530 is also received in the receiving cavity 502. Understandably, the fact that one end of the connecting post 530, the first abutment wall 503, and the first end of the return spring 610 are all located in the receiving cavity 502 makes the multi-leg bracket structure compact. The fact that the first end of the return spring 610 is received in the receiving cavity 502 also prevents the return spring 610 from bending or dislodging from its position during extension and retraction.

[0181] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The support rod assembly 100 includes a support rod body 110 and a mounting member 120. The mounting member 120 is mounted on the support rod body 110, and each connecting rod 400 is rotatably connected to the mounting member 120. A mounting cavity 101 is provided in the mounting member 120, and the mounting member 120 has a second abutment wall 102. A mounting post 520 is slidably mounted on the mounting member 120. Understandably, the support rod assembly 100 includes the support rod body 110 and the mounting member 120 to facilitate the assembly of the support rod assembly 100. The mounting member 120 is used both for rotatably connecting the connecting rods 400 and for mounting the initial opening member 500, making the structure of the multi-legged bracket compact.

[0182] Specifically, the mounting component has a through hole 103, and the connecting post 530 is slidably mounted in the through hole 103 of the support rod assembly, so that the initial opening component is slidably mounted in the support rod assembly.

[0183] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50The mounting post 520 has a receiving cavity 502, which is connected to one end of the mounting post 520. A first abutment wall 503 is located in the receiving cavity 502. The first end of the return spring 610 is received in the receiving cavity 502. The preliminary opening member 500 also includes a connecting post 530, which is connected to the mounting post 520. One end of the connecting post 530 is received in the receiving cavity 502, and the return spring 610 is sleeved on the connecting post 530. The mounting member 120 has a retaining part 122, which is located in the preliminary opening member 500. In the initial position, the holding part 122 holds the connecting post 530; the preliminary opening member 500 also includes a stop member 580 installed on the connecting post 530. When the preliminary opening member 500 is in the initial position, the stop member 580 abuts against the holding part 122 to realize that the holding part 122 holds the connecting post 530; during the process of the preliminary opening member 500 returning from the third position to the initial position, the return spring 610 acts on the preliminary opening member 500 to make the stop member 580 move toward the holding part 122.

[0184] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50The mounting component 120 is installed at the bottom end of the support rod body 110. When at least three support foot assemblies 300 are opened to their maximum open state relative to the sliding sleeve assembly 200, the sliding sleeve assembly 200 abuts against the mounting component 120. The mounting component 120 includes a mounting portion 123 and a mounting protrusion 124 connected to the mounting portion 123. Each connecting rod 400 is rotatably connected to the mounting protrusion 124 of the mounting component 120. The mounting cavity 101 communicates with the mounting portion 123. The support rod body 110 has a mounting hole 104 communicating with its bottom end. The mounting portion 123 is inserted into the mounting hole 104. The support rod assembly 100 also includes a second fastener 130, which passes through the support rod body 110 and is fastened to the mounting portion 123. The sliding sleeve assembly 200 has a sliding cavity 201 that is slidably adapted to the support rod assembly 100. The inner wall of the support rod assembly 110 is provided with a sliding strip 210, which extends along the sliding direction of the sliding cavity 201. The outer wall of the support rod body 110 is provided with a sliding groove 105, which is adapted to the sliding strip 210. During the sliding of the sliding sleeve assembly 200 along the length of the support rod assembly 100, the sliding strip 210 slides in the sliding groove 105. The second fastener 130 includes a second head 131 and a second rod portion 132 connected to the second head 131. The second head 131 is accommodated in the sliding groove 105, and the second rod portion 132 passes through the support rod body 110 and is fastened to the mounting portion 123. When the sliding sleeve assembly 200 and the support rod assembly 100 are in contact, the second head 131 is accommodated in the sliding cavity 201 and is located between the bottom end of the sliding strip 210 and the bottom end of the sliding sleeve assembly 200. Understandably, the sliding sleeve assembly 200 abuts against the mounting part 120 to prevent the multi-leg bracket from having an excessively large opening angle, which would cause the support leg assembly 300 and the connecting rod 400 to deform, thus preventing damage to the multi-leg bracket during use.

[0185] Understandably, the second fastener 130 securely connects the mounting part 123 to the support rod body 110, and the mounting part 123 is not easily detached from the support rod body 110. The second fastener 130 can be a threaded fastener, a riveted fastener, etc.

[0186] Understandably, the cooperation between the sliding bar 210 and the sliding groove 105 makes the sliding sleeve assembly 200 slide more stably relative to the support rod assembly 100. By housing the second head 131 within the sliding groove 105, the possibility of the second head 131 scratching the user is reduced. Furthermore, the sliding groove 105 serves both to cooperate with the sliding bar 210 and to house the second head 131, resulting in a compact structure for the support rod assembly 100. When the sliding sleeve assembly 200 is in contact with the support rod assembly 100, the second head 131 is located between the bottom end of the sliding bar 210 and the bottom end of the sliding sleeve assembly 200, preventing the second head 131 from obstructing the sliding of the sliding sleeve assembly 200. Moreover, the second head 131 is housed within the sliding cavity 201, further preventing the second head 131 from scratching the user's hand. For example, there are two sliding bars 210, located on opposite sides of the sliding cavity 201; there are two sliding grooves 105, located on opposite sides of the support rod body 110; and there are two second fasteners 130, with their second heads 131 respectively housed within the two sliding grooves 105. Understandably, both the sliding bars 210 and the sliding grooves 105 extend along the sliding direction of the sliding sleeve assembly 200.

[0187] For example, when the sliding sleeve assembly 200 is in contact with the mounting member 120, the sliding sleeve assembly 200 is in contact with the mounting protrusion 124.

[0188] For example, the sliding sleeve assembly 200 has at least three first rotating portions 202, and the support foot assembly 300 has second rotating portions 311. The second rotating portions 311 of the at least three support foot assemblies 300 are rotatably connected to the corresponding first rotating portions 202. The first rotating portion 202 is a shaft and the second rotating portion 311 is a hole, or the first rotating portion 202 is a hole and the second rotating portion 311 is a shaft. For example, the support rod assembly 100 has a third rotating portion 106, and the connecting rod 400 has a fourth rotating portion 410. The third rotating portion 106 and the fourth rotating portion 410 are rotatably engaged. The third rotating portion 106 is a hole and the fourth rotating portion 410 is a shaft, or the third rotating portion 106 is a shaft and the fourth rotating portion 410 is a hole. For example, the support foot assembly 300 has a fifth rotating part 301, and the connecting rod 400 has a sixth rotating part 420. The fifth rotating part 301 and the sixth rotating part 420 are rotatably engaged. The fifth rotating part 301 is a hole and the sixth rotating part 420 is a shaft, or the fifth rotating part 301 is a shaft and the sixth rotating part 420 is a hole.

[0189] For example, the mounting member 120 includes a first mounting sub-member 120a and a second mounting sub-member 120b. The second mounting sub-member 120b is mounted on the first mounting sub-member 120a, and a second thread is provided on the first mounting sub-member 120a. The first mounting sub-member 120a includes a mounting portion 123 and a portion of a mounting protrusion 124. The second mounting sub-member 120b includes a portion of the mounting protrusion 124 and is mounted on the first mounting sub-member 120a to form the mounting protrusion 124. When the sliding sleeve assembly 200 abuts against the mounting member 120, the sliding sleeve assembly 200 abuts against the first mounting sub-member 120a. Specifically, the first mounting sub-component 120a is mounted to the second mounting sub-component 120b via a third fastener 125, which can be a threaded component, a riveted component, etc.; the third rotating part 106 is a hole, and the first mounting sub-component 120a and the second mounting sub-component 120b are combined to form the third rotating part 106. The advantage of this arrangement is that it facilitates the rotatable mounting of the connecting rod 400 to the support rod assembly 100. For example, one way to install the connecting rod 400 is to place the connecting rod 400 between the first mounting sub-component 120a and the second mounting sub-component 120b, and then mount the second mounting sub-component 120b to the first mounting sub-component 120a via the third fastener 125.

[0190] Specifically, the mounting cavity 101 is connected to the mounting part 123, and the retaining part 122 is provided in the mounting part 123. The second fastener 130 passes through the support rod body 110 and is fastened to the first mounting sub-part 120a.

[0191] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 When the support leg assembly 300 is retracted into the support rod assembly 100, the support leg assembly 300 is subjected to a retracting force that keeps it retracted into the support rod assembly 100. During the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 and then initially opening relative to the support rod assembly 100, the retracting force weakens or decreases to zero. Understandably, the weakening or zeroing of the retracting force on the support leg assembly 300 makes it easier for the support leg assembly 300 to further open, facilitating the open state of the support leg assembly 300 relative to the support rod assembly 100.

[0192] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50When the support foot assembly 300 is retracted into the support rod assembly 100, the support foot assembly 300 and the connecting rod 400 are magnetically attracted to each other. During the process of at least three support foot assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the attractive force of the connecting rod 400 on the support foot assembly 300 weakens or becomes zero. Understandably, the weakening of the attractive force of the connecting rod 400 on the support foot assembly 300 makes it easier for the support foot assembly 300 to open further, facilitating the open state of the support foot assembly 300 relative to the support rod assembly 100.

[0193] For example, the support foot assembly 300 includes a support foot body 310 and a magnetic member 320. The magnetic member 320 is detachably mounted to the support body. When the support foot assembly 300 is retracted into the support rod assembly 100, the magnetic member 320 magnetically attracts the connecting rod 400. For example, the magnetic member 320 is made of a permanent magnet material, such as an AlNiCo permanent magnet alloy, an IronChromiumCo permanent magnet alloy, permanent magnet ferrite, rare earth permanent magnet material, or composite permanent magnet material. For example, the connecting rod 400 is partially made of a soft magnetic material, such as cast iron, silicon steel, carbon steel, alloy steel, or soft magnet ferrite. The connecting rod 400 includes a soft magnetic body and a plating layer. The soft magnetic body is made of a soft magnetic material, and the plating layer is attached to the soft magnetic body.

[0194] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The multi-legged tripod is used to support electronic terminals or shooting aids. With at least three support leg components 300 retracted into the support rod assembly 100, the at least three support leg components 300 can be held handheld. During the initial opening process of the at least three support leg components 300 relative to the support rod assembly 100 from retracted relative to the support rod assembly 100, the angle of rotation of the support leg components 300 relative to the support rod assembly 100 is greater than or equal to 0.5°. Understandably, the handheld nature of the at least three support leg components 300 facilitates the user's handheld use of the multi-legged tripod; for example, a user can hold the at least three support leg components 300 for selfies. For example, when the at least three support leg components 300 are retracted into the support rod assembly 100, the at least three support leg components 300 are cylindrical.

[0195] For example only, during the process of at least three support foot assemblies 300300 retracting relative to support rod assembly 100 to initially opening relative to support rod assembly 100, the angles of rotation of the support foot assemblies 300300 relative to support rod assembly 100 are 0.5°, 1°, 2°, 3°, etc.

[0196] In some other implementations, during the process of at least three support foot assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the angle of rotation of the support foot assembly 300 relative to the support rod assembly 100 is greater than or equal to 0.3°, for example, the angle can be 0.3°, 0.4°, 0.5°, etc.

[0197] In some implementations, during the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 and initially opening relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along a second direction. When the at least three support leg assemblies 300 are initially opened relative to the support rod assembly 100 and the second direction is along the direction of gravity, the self-weight of the moving component causes the at least three support leg assemblies 300 to open relative to the support rod assembly 100. The moving component includes the sliding sleeve assembly 200, at least three support leg assemblies 300, and at least three connecting rods 400. Understandably, the self-weight of the moving component causes the at least three support leg assemblies 300 to open "automatically," thereby facilitating the use of the multi-leg bracket.

[0198] Clearly, the second direction is along the length of the support rod assembly 100. During the initial opening of at least three support foot assemblies 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction, the support foot assembly 300 rotates relative to the sliding sleeve assembly 200, the support foot assembly 300 initially opens relative to the support rod assembly 100, the connecting rod 400 rotates relative to the support rod assembly 100, and the connecting rod 400 rotates relative to the support foot assembly 300.

[0199] Because the second direction is along the direction of gravity, the self-weight of the moving component includes at least the self-weight of the sliding sleeve assembly 200. During the initial opening of at least three support leg assemblies 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction, causing its center of gravity to drop. In some cases, the self-weight of the moving component also includes the self-weight of the support leg assembly 300 and the connecting rod 400. During the initial opening of at least three support leg assemblies 300 relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction, causing its center of gravity to drop. One end of the support leg assembly 300 slides with the sliding sleeve assembly 200, while the other end opens relative to the support rod assembly 100, causing its center of gravity to drop. The connecting rod 400 retracts relative to the support rod assembly 100, becoming open relative to the support rod assembly 100, causing its center of gravity to drop.

[0200] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The initial opening member 500 has a pressure-applying portion 560. A second external action includes a force acting on the initial opening member 500 along a first direction. Applying pressure to the pressure-applying portion 560 along the first direction causes the initial opening member 500 to translate relative to the support rod assembly 100 in that direction. Understandably, the user applies pressure to the pressure-applying portion 560, allowing the user to press and rotate the initial opening member 500 relative to the support rod assembly 100, thereby initially opening the support leg assembly 300 relative to the support rod assembly 100, thus facilitating the use of the multi-legged stand. For example, the user may press the pressure-applying portion 560 with their hand, or the user may strike the support surface to apply pressure to the initial opening member 500.

[0201] For example, at least three adjusting tabs 550 are connected to the pressure-applying part 560, and at least three push-pull parts 570 are connected to the pressure-applying part 560. This arrangement can enhance the structural strength of the initial opening member 500.

[0202] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The initial opening member 500 is installed at the bottom end of the support rod assembly 100; when at least three support foot assemblies 300 are retracted relative to the support rod assembly 100, the pressure application part 560 protrudes from the bottom end of the support foot assembly 300; when at least three support foot assemblies 300 are retracted relative to the support rod assembly 100, the pressure application part 560 of the initial opening member 500 impacts the support surface so that the support surface applies pressure to the pressure application part 560 in a first direction, so that the initial opening member 500 translates relative to the support rod assembly 100 in a first direction.

[0203] Understandably, the initial opening member 500 is located at the bottom end of the support rod assembly 100, and the pressure-applying part 560 protrudes from the bottom end of the support foot assembly 300, facilitating the impact of the pressure-applying part 560 of the initial opening member 500 onto the support surface. By impacting the support surface with the pressure-applying part 560, pressure can be applied to the pressure-applying part 560 more easily.

[0204] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50The initial opening member 500 has a pressure-applying portion 560. A second external action includes a force acting on the initial opening member 500 along a first direction, applying pressure to the pressure-applying portion 560 along the first direction, causing the initial opening member 500 to translate relative to the support rod assembly 100 in the first direction. During the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 to initially open relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along a second direction. When at least three support leg assemblies 300 retract relative to the support rod assembly 100 and the second direction is along the direction of gravity, the pressure-applying portion of the initial opening member 500... 560 impacts the support surface along the second direction, and the initial opening member 500 translates relative to the support rod assembly 100 along the first direction, thereby initially opening at least three support leg assemblies 300 relative to the support rod assembly 100. After the pressure portion of the initial opening member impacts the support surface along the second direction, and the second direction is along the direction of gravity, causing at least three of the support leg assemblies to initially open relative to the support rod assembly, the self-weight and inertia of the moving component cause at least three support leg assemblies 300 to open relative to the support rod assembly 100. The moving component includes a sliding sleeve assembly 200, at least three support leg assemblies 300, and at least three connecting rods 400. It is understood that the self-weight and inertia of the moving component cause at least three support leg assemblies 300 to open "automatically," thereby facilitating the use of the multi-leg bracket.

[0205] Understandably, when the pressure part 560 of the initial opening component 500 impacts the support surface in the second direction, the moving component still maintains its inertia of moving in the second direction.

[0206] Since the second direction is along the direction of gravity, the self-weight of the moving component includes at least the self-weight of the sliding sleeve assembly 200. Since the multi-leg bracket impacts the support surface along the second direction, the inertial effect of the moving component includes at least the inertial effect of the sliding sleeve assembly 200. During the process of at least three support leg assemblies 300 initially opening relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along the second direction under the action of inertia, and the center of gravity of the sliding sleeve assembly 200 drops, thereby causing the support leg assembly 300 to open relative to the support rod assembly 100. In some cases, the self-weight of the moving component also includes the self-weight of the support foot assembly 300 and the self-weight of the connecting rod 400. The inertia of the moving component also includes the inertia of the support foot assembly 300 and the inertia of the connecting rod 400. During the process of at least three support foot assemblies 300 initially opening relative to the support rod assembly 100, the moving component slides the sliding sleeve assembly 200 along the second direction under its own weight and inertia, the center of gravity of the sliding sleeve assembly 200 drops, and the support foot assembly 300... Under its own weight and inertia, one end of the support foot assembly 300 slides with the sliding sleeve assembly 200, and the other end opens relative to the support rod assembly 100. The center of gravity of the support foot assembly 300 drops. Under its own weight and inertia, the connecting rod 400 closes relative to the support rod assembly 100 and opens relative to the support rod assembly 100. The center of gravity of the connecting rod 400 drops, thereby causing at least three support foot assemblies 300 to open relative to the support rod assembly 100.

[0207] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 50 The support foot assembly 300 has a contact surface 302. During the translational movement of the initial opening member 500 along the first direction, the push part 570 contacts the contact surface 302 of the corresponding support foot assembly 300. The angle between the outer normal direction of the contact surface 302 and the first direction is greater than 90° to facilitate the initial opening of the support foot assembly 300 relative to the support rod assembly 100. The angle between the outer normal direction of the contact surface 302 and the first direction is greater than 90°. During the translational movement of the initial opening member 500 along the first direction, the push part 570 pushes against the contact surface 302, thereby facilitating the opening of the support foot assembly 300 relative to the support rod assembly 100. For example, the contact surface 302 is a plane or a curved surface.

[0208] Specifically, at least three support foot assemblies 300 are opened to their maximum open state relative to the support rod assembly 100, and at least three support foot assemblies 300 are supported on the support surface, with the contact surface 302 in contact with the support surface. More specifically, each support foot assembly 300 includes an anti-slip pad 330 and a support foot body 310, with the anti-slip pad 330 located at the bottom end of the support foot body 310, and the contact surface 302 located on the anti-slip pad 330.

[0209] In some implementation methods, refer to Figure 33 , Figure 36 , Figure 37 , Figure 42 , Figure 47 , Figure 50 The initial opening member 500 is rotatably mounted on the support rod assembly 100. Applying a first external action to the initial opening member 500 causes it to rotate relative to the support rod assembly 100. The first external action includes a rotational torque acting on the initial opening member 500 about its rotation axis 501. The initial opening member 500 has at least three actuating portions 540, each corresponding to at least three support foot assemblies 300. During the rotation of the initial opening member 500 from its initial position to its second position, the actuating portions 540 actuate the corresponding support foot assemblies 300, causing the at least three support foot assemblies 300 to retract relative to the support rod assembly 100 and then initially open relative to the support rod assembly 100, facilitating the opening of the at least three support foot assemblies 300 relative to the support rod assembly 100. It is understood that the number of actuating portions 540 is the same as the number of pushing portions 570.

[0210] Specifically, at least three actuating portions 540 and at least three push portions 570 are arranged alternately, with each actuating portion 540 located between two adjacent push portions 570 and each push portion 570 located between two adjacent actuating portions 540.

[0211] In some implementation methods, refer to Figure 34 , Figure 37 During the rotation of the initial opening member 500 relative to the support rod assembly 100, the initial opening member 500 can be held in any one of at least three holding positions, the number of holding positions being the same as the number of support foot assemblies 300; any one of the at least three holding positions is the initial position, and the holding position adjacent to the initial position is the second position.

[0212] It should be understood that any one of the at least three holding positions is the initial position, that is, the initial opening member 500 being in any holding position is equivalent to the initial opening member 500 being in the initial position. Rotation of the initial opening member 500 can cause the actuating part 540 to actuate the corresponding support foot assembly 300, or the initial opening member 500 can be translated along the first direction to cause the push part 570 to push the corresponding support foot assembly 300.

[0213] Understandably, the support foot assembly 300 corresponding to the actuating part 540 of the initial opening member 500 is different in different corresponding holding positions, and the support foot assembly 300 corresponding to the actuating part 570 of the initial opening member 500 is different in different corresponding holding positions.

[0214] For example, the number of support foot assemblies 300 is 3, 4, 5, etc., and the number of positions maintained is 3, 4, 5, etc.

[0215] Understandably, the holding position can refer to a specific location or a range of locations. During the rotation of the initial opening member 500 relative to the support rod assembly 100, the initial opening member 500 remains in the holding position when no external force is applied to it; or, during the rotation of the initial opening member 500 relative to the support rod assembly 100, if the rotational torque of the first external force is less than the holding torque of the initial opening member 500, the initial opening member 500 remains in the holding position.

[0216] In some implementation methods, refer to Figure 34 , Figure 37 The multi-leg bracket also includes a return spring 610, which acts on the initial opening member 500. The initial opening member 500 has a first holding portion 581, and the support rod assembly 100 has a second holding portion 122a. The first holding portion 581 is held at different positions on the second holding portion 122a to keep the initial opening member 500 in different holding positions. During the process of applying a first external force to the initial opening member 500 to rotate relative to the support rod assembly 100, the initial opening member 500 slides relative to the support rod assembly 100 and the return spring 610 extends and retracts, and the first holding portion 581 disengages from or is held in the second holding portion 122a. When the initial opening member 500 stops rotating relative to the support rod assembly 100, the return spring 610 acts on the initial opening member 500 to make the first holding portion 581 hold in the second holding portion 122a, and the return spring 610 causes the initial opening member 500 to return to its initial position.

[0217] Understandably, the return spring 610 serves two purposes: firstly, it engages the first latching part 581 with the second latching part 122a; secondly, its extension and contraction facilitates the disengagement of the first latching part 581 from the second latching part 122a. During the engagement or disengagement of the first latching part 581 with the second latching part 122a, the return spring 610 extends and contracts. This multi-functionality of the return spring 610 contributes to the compact structure of the multi-legged bracket.

[0218] Understandably, the first holding part 581 can be held in at least three positions of the second holding part 122a, so that the initial opening part 500 can be held in at least three holding positions.

[0219] For example, the first holding part 581 is provided on the stop 580 of the initial opening part 500, and the second holding part 122a is provided on the mounting part 120 of the support rod assembly 100. More specifically, the second holding part 122a is provided on the second mounting part 120b.

[0220] In some implementation methods, refer to Figure 34 , 37 The first holding portion 581 includes at least one first holding protrusion, and the second holding portion 122a includes at least three second holding grooves. At least one first holding protrusion is held in different at least one second holding groove so that the first holding portion 581 is held in different positions in the second holding portion 122a. The second holding grooves are open so that the first holding protrusion can disengage from the second holding groove during the rotation of the initial opening member 500 relative to the support rod assembly 100. During the rotation of the initial opening member 500 relative to the support rod assembly 100 to disengage the first holding protrusion from the second holding groove, the first holding protrusion slides across the inner wall of the second holding groove. When the initial opening member 500 stops rotating relative to the support rod assembly 100, the return spring 610 acts on the initial opening member 500 to hold at least one first holding protrusion into the corresponding at least one second holding groove.

[0221] Understandably, the second retaining groove is open to facilitate the first retaining protrusion disengaging from the second retaining groove during the process of applying a first external force to the initial opening member 500 to rotate relative to the support rod assembly 100.

[0222] For example, the second retaining groove is V-shaped.

[0223] In other embodiments, the first holding portion 581 includes at least three first holding grooves, and the second holding portion 122a includes at least one second holding protrusion. The at least one second holding protrusion is held in different at least one first holding groove so that the first holding portion 581 is held in different positions in the second holding portion 122a. The first holding groove is open. During the process of the initial opening member 500 applying a first external force to rotate the initial opening member 500 relative to the support rod assembly 100, the second holding protrusion slides across the inner wall of the first holding groove. Understandably, the first retaining groove is open, facilitating the disengagement of the second retaining protrusion from the first retaining groove during the rotation of the initial opening member 500 relative to the support rod assembly 100 caused by the application of a first external force to the initial opening member 500. During this rotation, the second retaining protrusion slides across the inner wall of the first retaining groove. When the initial opening member 500 stops rotating relative to the support rod assembly 100, the return spring 610 acts on the initial opening member 500 to engage at least one second retaining protrusion with at least one corresponding first retaining groove. For example, the first retaining groove may be V-shaped.

[0224] In some implementation methods, refer to Figure 34 , Figure 37 The support rod assembly 100 has at least three partition protrusions 122b, and the at least three partition protrusions 122b and at least three second retaining grooves are distributed alternately, and the space between two adjacent partition protrusions 122b is the second retaining groove.

[0225] The separating protrusion 122b gradually narrows along the first direction and the first side portion 581a of the first retaining protrusion gradually narrows in the opposite direction of the first direction. The first side portion of the first retaining protrusion is on the side of the first retaining protrusion close to the separating protrusion, so that when the initial opening member 500 stops rotating relative to the support rod assembly 100, at least one first retaining protrusion engages with at least one corresponding second retaining groove.

[0226] Understandably, both the dividing protrusion 122b and the first side of the first retaining protrusion gradually narrow, facilitating the insertion of the first retaining protrusion into the second retaining groove. Understandably, the inner wall of the second retaining groove is on the dividing protrusion, and the retaining portion includes the dividing protrusion 122b.

[0227] Understandably, when the initial opening member 500 rotates relative to the support rod assembly 100 to any angle, the first retaining protrusion of the initial opening member 500 can engage or disengage from the second retaining groove under the action of the return spring 610. For example, when the initial opening member 500 rotates to a certain angle, the first retaining protrusion is precisely aligned with the second retaining groove, and under the action of the return spring 610, the first retaining protrusion of the initial opening member 500 engages in the second retaining groove. As another example, when the initial opening member 500 rotates to another angle, the second retaining protrusion is not aligned with the second retaining groove, and under the action of the return spring 610, the first retaining protrusion of the initial opening member 500 engages in the second retaining groove, while the initial opening member 500 rotates during the process of the first retaining protrusion engaging in the second retaining groove.

[0228] In some implementation methods, refer to Figure 34 , Figure 37 The initial opening member 500 has a stop member 580, and the support rod assembly 100 has a retaining portion 122. When the initial opening member 500 is in its initial position, the retaining portion 122 retains the stop member 580 to prevent the initial opening member 500 from disengaging from the support rod assembly 100. The stop member 580 includes a first retaining portion 581, and the retaining portion 122 includes a second retaining portion 122a. The second retaining portion 122a retains the first retaining portion 581 so that the retaining portion 122 retains the stop member 580. It is understood that the first retaining portion 581 and the second retaining portion 122a are used both to hold the initial opening member 500 in different holding positions and to prevent the initial opening member 500 from disengaging from the support rod assembly 100, thereby making the structure of the multi-legged bracket compact.

[0229] In some implementation methods, refer to Figure 34 During the rotation of the initial opening member 500 relative to the support rod assembly 100, the initial opening member 500 can be held in any one of at least three holding positions, the number of holding positions being the same as the number of support foot assemblies 300; any one of the at least three holding positions is the initial position.

[0230] It should be understood that any one of the at least three holding positions is the initial position, that is, the initial opening member 500 in any holding position is equivalent to the initial opening member 500 in the initial position. The initial opening member 500 translates along the first direction to make the push part 570 push the corresponding support foot assembly 300.

[0231] In some implementation methods, refer to Figure 33 , 47 The initial opening member 500 has a rotation adjustment part, and the user can apply a rotational torque about the rotation axis 501 to the rotation adjustment part by hand to rotate the initial opening member 500 from the initial position to the second position.

[0232] In some implementation methods, refer to Figure 44 The number of support foot assemblies 300 is 3, the number of touch parts 540 is 3, and the rotation adjustment part includes 3 adjustment plates 550. The 3 adjustment plates 550 are centrally symmetrical about the rotation axis 501 of the initial opening member 500. The 3 adjustment plates 550 are respectively connected to the corresponding 3 touch parts 540. The two adjacent adjustment plates 550 form a force application space 505. The user's 3 fingers can be placed in the 3 force application spaces 505 respectively so that the user can adjust the rotation adjustment part by hand.

[0233] In some implementations, with at least three support foot assemblies 300 retracted relative to the support rod assembly 100, each actuating part 540 is located between two adjacent support foot assemblies 300.

[0234] This utility model embodiment also proposes an electronic terminal support device, including a support member 710 and a multi-leg bracket. The support member 710 is used to support the electronic terminal, and the support member 710 is installed on the support rod assembly 100 of the multi-leg bracket.

[0235] Reference Figure 29-55 This utility model embodiment also proposes a method of using a multi-leg bracket, the method comprising: providing a multi-leg bracket, wherein at least three support leg assemblies 300 of the multi-leg bracket are retracted into the support rod assembly 100 of the multi-leg bracket, and the initial opening member 500 of the multi-leg bracket is in an initial position; applying pressure to the initial opening member 500 along a first direction to cause the initial opening member 500 to translate along the first direction, thereby causing at least three support leg assemblies 300 to initially open relative to the support rod assembly 100; and causing at least three support leg assemblies 300 to open relative to the support rod assembly 100.

[0236] Understandably, the translational movement of the initial opening member 500 in the first direction can cause the support foot assembly 300 to open initially, thereby facilitating the opening of the support foot assembly 300 relative to the support rod assembly 100.

[0237] In some implementations, during the process of at least three support foot assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along a second direction; the step of opening the at least three support foot assemblies 300 relative to the support rod assembly 100 includes: the step of opening the at least three support foot assemblies 300 relative to the support rod assembly 100 includes making the second direction along the direction of gravity, and the self-weight of the moving assembly causing the at least three support foot assemblies 300 to open relative to the support rod assembly 100, the moving assembly including the sliding sleeve assembly 200, the at least three support foot assemblies 300 and the at least three connecting rods 400.

[0238] In some implementations, during the process of at least three support leg assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along a second direction; the step of applying pressure to the pressure part 560 along a first direction to cause the initial opening member 500 to translate along the first direction includes: the pressure part 560 of the initial opening member 500 impacts the support surface along the second direction, so that the initial opening member 500 translates relative to the support rod assembly 100 along the first direction and rotates relative to the support rod assembly 100, the second direction being along the direction of gravity; the step of opening at least three support leg assemblies 300 relative to the support rod assembly 100 includes: the self-weight and inertia of the moving component cause at least three support leg assemblies 300 to open relative to the support rod assembly 100, the moving component including the sliding sleeve assembly 200 of the multi-leg bracket, at least three support leg assemblies 300, and at least three connecting rods 400 of the multi-leg bracket.

[0239] This utility model embodiment also proposes a method of using a multi-legged bracket. The method includes: providing a multi-legged bracket, with at least three support leg assemblies 300 of the multi-legged bracket retracting into a support rod assembly 100 of the multi-legged bracket, and a preliminary opening member 500 of the multi-legged bracket in an initial position, the preliminary opening member 500 having a rotation adjustment part; the user applies a rotational torque about its rotation axis 501 to the rotation adjustment part of the preliminary opening member 500, causing the rotation adjustment part to rotate about the rotation axis 501 of the preliminary opening member 500, so that the preliminary opening member 500 rotates from the initial position to a second position, causing at least three support leg assemblies 300 to initially open relative to the support rod assembly 100; and opening at least three support leg assemblies 300 relative to the support rod assembly 100. It can be understood that the rotation of the preliminary opening member 500 can cause the support leg assemblies 300 to initially open, thereby facilitating the opening of the support leg assemblies 300 relative to the support rod assembly 100.

[0240] In some implementations, the number of support foot assemblies 300 is three, the number of touch parts 540 is three, and the rotation adjustment part includes three adjustment plates 550. The three adjustment plates 550 are centrally symmetrical about the rotation axis 501 of the initial opening member 500. The three adjustment plates 550 are respectively connected to the corresponding three touch parts 540, and two adjacent adjustment plates 550 form a force application space 505. The step of placing the user's three fingers in the three force application spaces 505 respectively, so that at least three support foot assemblies 300 are initially opened relative to the support rod assembly 100, includes: rotating the user's arm to apply a rotational torque about the rotation axis 501 of the initial opening member 500, so that the rotation adjustment part rotates about the rotation axis 501 of the initial opening member 500, so that the initial opening member 500 rotates from the initial position to the second position, so that at least three support foot assemblies 300 are initially opened relative to the support rod assembly 100.

[0241] In some implementations, during the process of at least three support foot assemblies 300 retracting relative to the support rod assembly 100 to initially opening relative to the support rod assembly 100, the sliding sleeve assembly 200 slides along a second direction; the step of opening the at least three support foot assemblies 300 relative to the support rod assembly 100 includes making the second direction along the direction of gravity, and the self-weight of the moving assembly causing the at least three support foot assemblies 300 to open relative to the support rod assembly 100, wherein the moving assembly includes the sliding sleeve assembly 200 of the multi-leg bracket, the at least three support foot assemblies 300, and the at least three connecting rods 400 of the multi-leg bracket.

[0242] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0243] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
