Abstract

This invention relates to a support leg, a monopod, and a support frame. The support leg includes a rod assembly, a base assembly, and a locking assembly. The rod assembly includes a first leg segment, a second leg segment, and a third leg segment that are sequentially sleeved together along the axial direction. The base assembly includes a first mounting seat and a second mounting seat, with the first mounting seat disposed between the first and second leg segments and the second mounting seat disposed between the second and third leg segments. The locking assembly includes a first locking element, a second locking element, a linkage shaft, a first flexible element, and a second flexible element.

Description

Technical Field

[0001] This invention relates to the field of photography technology, and in particular to a support leg, monopod, and support frame. Background Technology

[0002] The support legs of a support frame typically have multiple movable foot tubes to extend and retract the legs. Each adjacent foot tube has a locking mechanism, usually using a threaded knob or lever to restrict and release relative movement. When a user needs to unlock multiple foot tubes, they must adjust the locking mechanism on each foot tube individually, and also bend over to adjust the locking mechanism on the end foot tube. This process is cumbersome and inconvenient for the user. Summary of the Invention

[0003] The present invention provides a support leg, a monopod, and a support frame to solve the problem that when a user needs to unlock multiple legs, the user needs to adjust the locking structure on each leg individually, and the user also needs to bend over to adjust the locking structure on the end leg. This process is cumbersome and inconvenient for the user.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A supporting leg, comprising:

[0006] The rod assembly includes a first leg segment, a second leg segment, and a third leg segment that are sequentially sleeved on each other along the axial direction;

[0007] The seat assembly includes a first mounting base and a second mounting base, wherein the first mounting base is disposed between the first leg segment and the second leg segment, and the second mounting base is disposed between the second leg segment and the third leg segment;

[0008] A locking assembly includes a first locking member, a second locking member, a linkage shaft, a first flexible member, and a second flexible member. The first locking member is located on the first mounting base and can switch between a locked position and an unlocked position to restrict and release the relative movement between the first leg segment and the second leg segment. The second locking member is located on the second mounting base and can switch between a locked position and an unlocked position to restrict the relative movement between the second leg segment and the third leg segment. The linkage shaft is rotatably connected to the first mounting base and the second mounting base, respectively. The first flexible member is connected to the first locking member and the linkage shaft, respectively. The second flexible member is connected to the second locking member and the linkage shaft, respectively.

[0009] The linkage shaft can rotate around its axis to drive the first locking member and the second locking member to switch between the locked position and the unlocked position via the first flexible member and the second flexible member.

[0010] In one embodiment, the first locking member includes a first lock body, a second lock body, a locking pin, and a handle. The first lock body and the second lock body restrict the second leg segment between the first lock body and the second lock body. One end of the first lock body is connected to one end of the second lock body, and the other ends of the first lock body and the second lock body form a notch. The locking pin passes through the first lock body and the second lock body and is rotatably connected to the handle. The handle is connected to the first flexible member. When the linkage shaft rotates about its axial direction, the first flexible member drives the handle to rotate relative to the locking pin. The rotation of the handle causes the first lock body and the second lock body to move closer to each other to reduce the radial dimension of the notch, so that the first lock body and the second lock body simultaneously abut against the second leg segment to restrict the movement of the second leg segment relative to the first leg segment. The first locking member and the second locking member have the same structure.

[0011] In one embodiment, the end of the handle is provided with a cam, which, when the handle rotates relative to the locking pin, causes the first lock body and the second lock body to move closer to each other to reduce the radial dimension of the notch.

[0012] In one embodiment, one end of the first flexible member is connected to the linkage shaft, and the other end of the first flexible member passes through the inner wall of the first mounting base and the handle and is then connected to the linkage shaft; the locking assembly includes a first locking body and a second locking body, the first locking body and the second locking body being spaced apart from the first flexible member and restricting the handle between the first locking body and the second locking body; when the linkage shaft rotates about its axial direction, the first flexible member drives the first locking body to abut against the handle, thereby driving the handle to rotate relative to the locking pin; the linkage shaft can also rotate about its axial direction in the opposite direction, such that the first flexible member drives the second locking body to abut against the handle, thereby driving the handle to rotate in the opposite direction relative to the locking pin; wherein, the second flexible member is arranged in the same way as the first flexible member.

[0013] In one embodiment, the locking assembly includes a first rotating wheel and a second rotating wheel. The first rotating wheel is connected to the linkage shaft and circumferentially limited by the linkage shaft. Both first rotating wheels are connected to opposite ends of the first flexible member. When the linkage shaft rotates about its axial direction, the linkage shaft also synchronously drives the first rotating wheel to rotate, causing the first locking body to abut against the handle, so that the first flexible member drives the handle to rotate relative to the locking pin through the first locking body. When the linkage shaft rotates in the opposite direction about its axial direction, the linkage shaft also synchronously drives the first rotating wheel to rotate in the opposite direction, causing the second locking body to abut against the handle, so that the first flexible member drives the handle to rotate in the opposite direction relative to the locking pin through the second locking body. The second rotating wheel and the second flexible member have the same connection structure.

[0014] In one embodiment, the linkage shaft is provided with an outwardly convex curved surface and a flat surface. The first wheel and the second wheel are both provided with connecting holes adapted to the shape of the linkage shaft. The connecting holes are for the linkage shaft to pass through, and the hole wall of the connecting hole abuts against the flat surface to restrict the first wheel and the second wheel from rotating relative to the linkage shaft about the axial direction of the linkage shaft.

[0015] In one embodiment, the first leg segment, the second leg segment, and the third leg segment each include two rods extending axially and arranged side by side, with two axially adjacent rods sleeved together. The two rods of the first leg segment are simultaneously connected to the first mounting base, and the two rods of the second leg segment are simultaneously connected to the second mounting base, or the two rods of the third leg segment are simultaneously connected to the second mounting base.

[0016] In one embodiment, the seat assembly includes a fixed seat connected to the end of the first leg segment away from the first mounting seat and rotatably connected to the linkage shaft. The locking assembly includes a drive handle connected to the linkage shaft and circumferentially limiting the linkage shaft. The opposite ends of the drive handle are located on opposite sides of the fixed seat to restrict the linkage shaft from disengaging from the fixed seat in the axial direction. The drive handle can drive the linkage shaft to rotate about its axial direction.

[0017] The present invention also provides a monopod, including the aforementioned support leg, gimbal base and support base, wherein the gimbal base and the support base are respectively connected to opposite ends of the support leg.

[0018] The present invention also provides a support frame, including a plurality of support legs and a gimbal base as described above, wherein the plurality of support legs are rotatably connected to the gimbal base so as to be able to be unfolded and folded.

[0019] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0020] This invention provides a support leg and a monopod support frame. Since the linkage shaft can directly drive the first and second locking components to switch between the locked and unlocked positions through the first and second flexible components, it can limit and release the extension and retraction of the support leg. The operation is simple, and the user does not need to adjust the locking structure on each leg tube individually, nor does the user need to bend over to adjust the locking structure on the end leg tube, making it convenient for the user.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] First Embodiment

[0038] refer to Figure 1This invention provides a support frame 1 that can switch between an unfolded state and a retracted state. In the unfolded state, the support frame 1 forms a tripod structure and is used to mount shooting equipment to achieve stable shooting and facilitate user use. In the retracted state, the support frame 1 is closed for easy storage. The shooting equipment can be, but is not limited to, smartphones, tablets, cameras, camcorders, etc.

[0039] Continue to refer to Figure 1 The support frame 1 includes a gimbal base 10 and multiple support legs 20. The gimbal base 10 can be used to mount shooting equipment, enabling the shooting equipment to be connected and fixed to the support frame 1. The multiple support legs 20 are rotatably connected to the gimbal base 10 so that they can be extended and retracted, allowing the support frame 1 to switch between extended and retracted states. In the extended state, the gimbal base 10 and the multiple support legs 20 form a tripod structure. In the retracted state, the multiple support legs 20 are brought close together for easy storage.

[0040] The support leg 20 can be extended and shortened to adjust the shooting height of the shooting device, allowing the shooting device to shoot at multiple shooting heights, making it convenient for users to complete shooting activities.

[0041] refer to Figure 2 The support leg 20 includes a base assembly 201, a rod assembly 202, and a locking assembly 203. The rod assembly 202 is connected to the base assembly 201, and its length can be extended and shortened to allow the support leg 20 to extend and shorten. The locking assembly 203 is mounted on the base assembly 201 and can switch between a locked position and an unlocked position to restrict and release the extension and shortening of the rod assembly 202.

[0042] Continue to refer to Figure 2 The seat assembly 201 includes a first mounting base 204 and a second mounting base 205. The first mounting base 204 and the second mounting base 205 have the same structure. It is understood that in other embodiments, the structures of the first mounting base 204 and the second mounting base 205 may be different. Therefore, this invention does not limit the specific structure of the first mounting base 204 and the second mounting base 205. Both the first mounting base 204 and the second mounting base 205 are connected to the rod assembly 202 to achieve a fixed connection between the seat assembly 201 and the rod assembly 202.

[0043] Continue to refer to Figure 2 The base assembly 201 includes a fixed base 206, which is connected to the end of the rod assembly 202 near the gimbal base 10. The fixed base 206 is also rotatably connected to the gimbal base 10. The rod assembly 202 rotates with the gimbal base 10 through the fixed base 206, thereby realizing the rotatable connection between the support leg 20 and the gimbal base 10.

[0044] It is understood that in other embodiments, the fixing seat 206 can be omitted, in which case the rod assembly 202 can be directly rotatably connected to the gimbal base 10, or the fixing seat 206 can be set at the end of the rod assembly 202 away from the gimbal base 10. Therefore, the present invention does not limit the specific setting method of the fixing seat 206.

[0045] refer to Figure 3 The rod assembly 202 includes a first leg segment 207, a second leg segment 208, and a third leg segment 209 that are sequentially sleeved together along the axial direction. These three segments are movable relative to each other to extend or shorten, thereby enabling the support leg 20 to extend or shorten. The end of the first leg segment 207 away from the second leg segment 208 is connected to a fixing seat 206, thus connecting and fixing the rod assembly 202 to the fixing seat 206. It is understood that in other embodiments, the fixing seat 206 may also be connected to the end of the third leg segment 209 away from the second leg segment 208. Therefore, the present invention does not limit the specific location of the fixing seat 206. The end of the first leg segment 207 away from the fixed seat 206 is connected to the first mounting seat 204. The end of the second leg segment 208 near the first leg segment 207 is fitted inside the first leg segment 207. The end of the second leg segment 208 away from the first leg segment 207 is connected to the second mounting seat 205. The end of the third leg segment 209 near the second leg segment 208 is fitted inside the second leg segment 208. This achieves the connection and fixation between the rod assembly 202 and the seat assembly 201.

[0046] It is understood that in other embodiments, the two opposite ends of the second leg segment 208 are respectively connected and fixed to the first mounting base 204 and the second mounting base 205. In this case, both the first leg segment 207 and the third leg segment 209 are fitted inside the second leg segment 208. Alternatively, among the two adjacent third leg segments 209 and second leg segments 208, the third leg segment 209 is connected to the second mounting base 205, and the second leg segment 208 is fitted inside the third leg segment 209. Among the two adjacent second leg segments 208 and first leg segments 207, the second leg segment 208 is connected to the first mounting base 204, and the first leg segment 207 is fitted inside the second leg segment 208. Therefore, the present invention does not limit the specific arrangement of the first leg segment 207, the second leg segment 208, the third leg segment 209, the first mounting base 204, and the second mounting base 205.

[0047] It should be noted that when a higher shooting height is required, the overall length of the support leg 20 can be increased. In this case, the rod assembly 202 can be provided with multiple leg segments, that is, multiple third leg segments 209 can be provided in sequence. At the same time, the number of second mounting seats 205 is also multiple and they are provided between two adjacent third leg segments 209. In other embodiments, the first leg segment 207 and the second leg segment 208 can be provided in the same way.

[0048] Continue to refer to Figure 3 In one embodiment, the first leg segment 207, the second leg segment 208, and the third leg segment 209 each include two rods 210 extending axially and arranged side by side, with the two axially adjacent rods 210 sleeved together. In this embodiment, among the two axially adjacent rods 210 of the first leg segment 207 and the second leg segment 208, the two rods 210 of the first leg segment 207 are simultaneously connected to the first mounting base 204, and the two rods 210 of the second leg segment 208 are sleeved inside the two rods 210 of the first leg segment 207. Simultaneously, among the two axially adjacent rods 210 of the second leg segment 208 and the third leg segment 209, the two rods 210 of the second leg segment 208 are simultaneously connected to the second mounting base 205, and the two rods 210 of the third leg segment 209 are sleeved inside the two rods 210 of the second leg segment 208.

[0049] It is understood that in other embodiments, in the two axially adjacent rods 210 of the first leg segment 207 and the second leg segment 208, the two rods 210 of the first leg segment 207 are fitted inside the two rods 210 of the second leg segment 208, and the two rods 210 of the second leg segment 208 are simultaneously connected to the first mounting base 204. At the same time, in the two axially adjacent rods 210 of the second leg segment 208 and the third leg segment 209, the two rods 210 of the second leg segment 208 are fitted inside the two rods 210 of the third leg segment 209, and the two rods 210 of the third leg segment 209 are simultaneously connected to the second mounting base 205. Therefore, the present invention does not limit the specific fitting method of the two axially adjacent rods 210.

[0050] It should be noted that since the first leg segment 207, the second leg segment 208, and the third leg segment 209 each include two rods 210, the supporting leg 20 can support larger weights, thereby allowing the support frame 1 to mount larger shooting equipment. It is understood that in other embodiments, the first leg segment 207, the second leg segment 208, and the third leg segment 209 may also include only a single rod 210 or multiple rods 210; therefore, this invention does not limit the number of rods 210.

[0051] refer to Figure 4 and Figure 5The locking assembly 203 includes a first locking member 211, a second locking member 212, a linkage shaft 213, a first flexible member 214, and a second flexible member 215. The first locking member 211 is located on the first mounting base 204 and can switch between a locked position and an unlocked position to restrict and release the relative movement between the first leg segment 207 and the second leg segment 208. The second locking member 212 is located on the second mounting base 205 and can switch between a locked position and a fixed position to restrict and release the relative movement between the second leg segment 208 and the third leg segment 209, thereby releasing or restricting the extension and retraction of the support leg 20. The linkage shaft 213 is rotatably connected to the first mounting base 204, the second mounting base 205, and the fixed base 206, and can rotate around its axial direction. The first flexible member 214 is connected to the first locking member 211 and the linkage shaft 213, and the second flexible member 215 is connected to the second locking member 212 and the linkage shaft 213, so that when the linkage shaft 213 rotates around its axial direction, the linkage shaft 213 can drive the first locking member 211 and the second locking member 212 to switch between the locked position and the unlocked position through the first flexible member 214 and the second flexible member 215, so as to restrict and release the extension and retraction of the support leg 20.

[0052] It should be noted that in this embodiment, the first locking member 211 and the second locking member 212 have the same structure, so only the first locking member 211 will be explained below. It is understood that in other embodiments, the structures of the first locking member 211 and the second locking member 212 may be different. In this case, the first locking member 211 and the second locking member 212 only need to be able to restrict and release the relative movement of two adjacent leg segments. Therefore, this invention does not impose any limitations on the specific structure of the first locking member 211 and the second locking member 212.

[0053] It should also be noted that in this embodiment, the first flexible member 214 and the second flexible member 215 have the same structure, and the flexible member can be a flexible rope, a flexible steel wire, etc. It is understood that in other embodiments, the structures of the first flexible member 214 and the second flexible member 215 may be different. For example, the first flexible member 214 may be a flexible rope and the second flexible member 215 may be a flexible steel wire. At the same time, the flexible member can also be a rope made of other flexible materials. Therefore, the present invention does not limit the specific structure and type of the first flexible member 214 and the second flexible member 215.

[0054] It should be understood that when there are multiple third leg sections 209 and second mounting seats 205, the number of second locking members 212 and second flexible members 215 is also set accordingly, and the setting method of the second locking members 212 and the second flexible members 215 is the same as the setting method described above. At this time, the length of the linkage shaft 213 is extended to rotatably connect to multiple second mounting seats 205 and connect to multiple second flexible members 215.

[0055] In summary, in this invention, since the linkage shaft 213 can directly drive the first locking member 211 and the second locking member 212 to switch between the locked position and the unlocked position through the first flexible member 214 and the second flexible member 215, the extension and retraction of the support leg 20 can be restricted and released. The operation is simple, and the user does not need to adjust the locking structure on each leg tube individually, nor does the user need to bend over to adjust the locking structure on the end leg tube, making it convenient for the user.

[0056] Continue to refer to Figure 4 In one embodiment, the locking assembly 203 includes a first rotating wheel 216 and a second rotating wheel 217. The first rotating wheel 216 is connected to and circumferentially limited by the linkage shaft 213. The first rotating wheel 216 is located on the first mounting base 204 and connected to the opposite ends of the first flexible member 214. When the linkage shaft 213 rotates around its axial direction, the linkage shaft 213 also synchronously drives the first rotating wheel 216 to rotate, so that the first rotating wheel 216 drives the first locking member 211 to switch between the locked position and the unlocked position through the first flexible member 214. The second rotating wheel 217 is located on the second mounting base 205, and the connection structure between the second rotating wheel 217 and the second flexible member 215 is the same as the connection structure described above, and will not be repeated here.

[0057] It should be noted that when there are multiple second mounting bases 205 and multiple second flexible parts 215, the number of second rotating wheels 217 can also be set accordingly.

[0058] refer to Figure 6 In one embodiment, to achieve circumferential limiting between the first rotating wheel 216 and the linkage shaft 213, the linkage shaft 213 is provided with an outwardly convex curved surface 218 and a flat surface 219, both extending from one end of the linkage shaft 213 to the other. The first rotating wheel 216 is provided with a connecting hole 220 that matches the shape of the linkage shaft 213, through which the linkage shaft 213 passes. The wall of the connecting hole 220 abuts against the flat surface 219 to restrict the first rotating wheel 216 axially relative to the linkage shaft 213, thereby achieving circumferential limiting between the first rotating wheel 216 and the linkage shaft 213. Simultaneously, the second rotating wheel 217 is provided with the same arrangement as the first rotating wheel 216, and has the same structure as the first rotating wheel 216, thereby achieving circumferential limiting between the second rotating wheel 217 and the linkage shaft 213.

[0059] It should be noted that in other embodiments, the curved surface 218, the flat surface 219 and the connecting hole 220 can be omitted. In this case, the first rotating wheel 216 and the second rotating wheel 217 can be fixedly connected to the linkage shaft 213. Therefore, the present invention does not limit the specific arrangement of the curved surface 218, the flat surface 219 and the connecting hole 220.

[0060] It should be understood that in other embodiments, the first rotating wheel 216 and the second rotating wheel 217 can be omitted. In this case, the first flexible member 214 and the second flexible member 215 can be directly connected to the linkage shaft 213. Therefore, the present invention does not limit the specific arrangement of the first rotating wheel 216 and the second rotating wheel 217.

[0061] Continue to refer to Figure 2 In one embodiment, the locking assembly 203 includes a drive handle 221, which is connected to the linkage shaft 213 and circumferentially limits the linkage shaft 213. The two opposite ends of the drive handle 221 are located on opposite sides of the fixed seat 206, thereby restricting the linkage shaft 213 from axially disengaging from the first mounting seat 204, the second mounting seat 205, and the fixed seat 206, thus achieving axial fixation of the linkage shaft 213. Simultaneously, the user can also use the drive handle 221 to rotate the linkage shaft 213 around its axial direction, facilitating user operation of the linkage shaft 213.

[0062] It should be noted that the drive handle 221 is also provided with the connection hole 220 mentioned above. The drive handle 221 is connected to the linkage shaft 213 through the connection hole 220 to achieve circumferential positioning of the drive handle 221 and the linkage shaft 213. It can be understood that in other embodiments, the drive handle 221 may not be provided with the connection hole 220, in which case the drive handle 221 can be fixedly connected to the linkage shaft 213.

[0063] refer to Figure 7 In one embodiment, the first locking member 211 includes a first lock body 222, a second lock body 223, a locking pin 224, and a handle 225. The first lock body 222 and the second lock body 223 restrict the second leg segment 208 between the first lock body 222 and the second lock body 223. One end of the first lock body 222 is connected to one end of the second lock body 223, and the other end of the first lock body 222 and the other end of the second lock body 223 form a notch 226. The locking pin 224 passes through the first lock body 222 and the second lock body 223 and is rotatably connected to the handle 225. The handle 225 is connected to the first flexible member 214.

[0064] When the linkage shaft 213 drives the first rotating wheel 216 to rotate in the forward direction around the axis, the first rotating wheel 216 drives the handle 225 to rotate relative to the locking pin 224 through the first flexible member 214. The rotation of the handle 225 causes the first lock body 222 and the second lock body 223 to move closer to each other to reduce the radial dimension of the notch 226, so that the first lock body 222 and the second lock body 223 simultaneously abut against the second leg section 208. Since the first leg section 207 is connected and fixed to the first mounting base 204, and the first lock body 222 and the second lock body 223 are both located in the first mounting base 204, the movement of the second leg section 208 relative to the first mounting base 204 is restricted, and the movement of the second leg section 208 relative to the first leg section 207 is also restricted. At this time, the first locking member 211 switches from the unlocked position to the locked position.

[0065] When the linkage shaft 213 drives the first rotating wheel 216 to rotate in the opposite direction around the axis, the first rotating wheel 216 drives the handle 225 to rotate in the opposite direction relative to the locking pin 224 through the first flexible member 214, so as to release the restriction of the handle 225 on the first lock body 222 and the second lock body 223, so that the first lock body 222 and the second lock body 223 move away from each other and increase the radial dimension of the notch 226. At this time, the first lock body 222 and the second lock body 223 reduce or eliminate the contact with the second leg section 208, so that the second leg section 208 can move relative to the first mounting base 204, that is, the second leg section 208 can move relative to the first leg section 207. At this time, the first locking member 211 switches from the locked position to the unlocked position.

[0066] It should be noted that in this embodiment, since both the first leg segment 207 and the second leg segment 208 include two rods 210, the number of first lock bodies 222 and second lock bodies 223 are two and mirror-image arranged, thereby restricting the two rods 210 between the first lock bodies 222 and the second lock bodies 223. One of the two first lock bodies 222 and the two second lock bodies 223 is interconnected. In this embodiment, the proximal ends of the two first lock bodies 222 are interconnected. It can be understood that in other embodiments, the proximal ends of the two second lock bodies 223 can also be interconnected. The locking pin 224 passes through the first lock body 222, and the handle 225 is located on the side where the second lock body 223 is located. The locking principle of the two first lock bodies 222 and the two second lock bodies 223 for the two rods 210 is the same as the above-described locking principle, and will not be repeated here.

[0067] It is understood that in other embodiments, the first leg segment 207 and the second leg segment 208 may also include a single rod 210. In this case, the number of the first lock body 222 and the second lock body 223 is also a single one. Therefore, the present invention does not limit the number of the first lock body 222 and the second lock body 223.

[0068] It should also be noted that in this embodiment, the handle 225 is located on the side where the second lock body 223 is located. It can be understood that in other embodiments, the handle 225 may also be located on the side where the first lock body 222 is located. Therefore, the present invention does not limit the specific location of the handle 225.

[0069] Continue to refer to Figure 7 In one embodiment, a cam 227 is provided at the end of the handle 225. When the handle 225 rotates forward relative to the locking pin 224, the handle 225 abuts against the second lock body 223 through the cam 227, so as to drive the first lock body 222 and the second lock body 223 to move closer to each other to reduce the radial dimension of the notch 226, so that the first lock body 222 and the second lock body 223 abut against the second leg section 208 at the same time, thereby restricting the movement of the second leg section 208 relative to the first leg section 207. At this time, the first locking member 211 switches from the unlocked position to the locked position.

[0070] Simultaneously, when the handle 225 rotates in the opposite direction relative to the locking pin 224, the handle 225 causes the protruding end of the cam 227 to disengage from the second lock body 223, so that the first lock body 222 and the second lock body 223 can be reset, thereby reducing or eliminating the degree of contact between the first lock body 222 and the second lock body 223 and the second leg section 208, so that the second leg section 208 can move relative to the first mounting base 204, that is, the second leg section 208 can move relative to the first leg section 207. At this time, the first locking member 211 switches from the locked position to the unlocked position.

[0071] Continue to refer to Figure 6 In one embodiment, one end of the first flexible member 214 is connected to the first rotating wheel 216, and the other end of the first flexible member 214 passes through the inner wall of the first mounting base 204 and the handle 225 and is then connected to the first rotating wheel 216. The locking assembly 203 includes a first locking body 228 and a second locking body 229. The first locking body 228 and the second locking body 229 are spaced apart from each other on the first flexible member 214 and restrict the handle 225 between the first locking body 228 and the second locking body 229.

[0072] When the linkage shaft 213 drives the first rotating wheel 216 to rotate in the forward direction, the first rotating wheel 216 drives the first locking body 228 to abut against the handle 225 through the first flexible member 214, thereby causing the first flexible member 214 to drive the handle 225 to rotate in the forward direction relative to the locking pin 224 through the first locking body 228. At the same time, when the linkage shaft 213 drives the first rotating wheel 216 to rotate in the reverse direction, the first rotating wheel 216 drives the second locking body 229 to abut against the handle 225 through the first flexible member 214, thereby causing the first flexible member 214 to drive the handle 225 to rotate in the reverse direction relative to the locking pin 224 through the second locking body 229, so as to realize the relative rotation of the handle 225 and the locking pin 224.

[0073] It is understood that in other embodiments, when the first rotating wheel 216 is omitted, the same two ends of the first flexible member 214 can be directly connected to the linkage shaft 213. Similarly, when the second rotating wheel 217 is omitted, the second flexible member 215 can be set in the same way. Therefore, the present invention does not limit the specific connection method of the first flexible member 214 and the second flexible member 215.

[0074] It should be understood that in other embodiments, the first card body 228 and the second card body 229 can be omitted. In this case, the two ends of the first flexible member 214 can be connected to the handle 225 and the first rotating wheel 216 respectively. Therefore, the present invention does not limit the specific arrangement of the first card body 228 and the second card body 229.

[0075] It should be noted that the second flexible member 215 is configured in the same way as the first flexible member 214, that is, the second flexible member 215 is also provided with a first card body 228 and a second card body 229, and the operating principle of the first card body 228 and the second card body 229 provided on the second flexible member 215 is the same as the operating principle of the first flexible member 214. Furthermore, when there are multiple second flexible members 215 or multiple first flexible members 214, the number of first card bodies 228 and second card bodies 229 is also set accordingly.

[0076] It should also be noted that the first rotating wheel 216 is provided with a locking hole, and the end of the first flexible member 214 passes through the locking hole and is locked to the first rotating wheel 216, so as to realize the connection and fixation between the first rotating wheel 216 and the first flexible member 214. The second rotating wheel 217 and the second flexible member 215 are set in the same way.

The gimbal base 10 and support seat 30 are located at opposite ends of the support legs 20, and the number of support legs 20 is single. Specifically, the gimbal base 10 is connected to the end of the first leg segment 207 away from the first mounting base 204 and is used to mount the shooting equipment, so as to realize the fixed installation of the shooting equipment and the monopod 2. At this time, the gimbal base 10 replaces the fixed seat 206 installed on the first leg segment 207. The handle 225 is connected to the gimbal base 10, or the fixed seat 206 is omitted, and the gimbal base 10 is installed at the end of the first leg segment 207, or the gimbal base 10 is the fixed seat 206 mentioned above. The support seat 30 is connected to the end of the third leg segment 209 away from the second mounting base 205 to provide fixed support for the gimbal base 10 and the support legs 20.

[0079] It is understood that in other embodiments, the positions of the gimbal base 10 and the support base 30 can be interchanged. That is, the support base 30 is connected to the end of the first leg segment 207 away from the first mounting base 204, and the gimbal base 10 is connected to the end of the third leg segment 209 away from the second mounting base 205. Therefore, the present invention does not limit the specific setting position of the gimbal base 10 and the support base 30.

[0080] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
