The specific structure can be: a bearing 104 and a connecting column 105 are provided on the top of the rotating bearing seat 103. The upper end of the connecting column 105 is connected to the seat cushion 101. Figure 3 The seat cushion 101 is fixed to the upper end face of the connecting column 105 by screws; the lower end of the connecting column 105 is assembled on the bearing 104 and is connected to the locking member 106 passing through the bearing 104 from bottom to top, and the connecting column 105 is preferably a cylinder.

[0044] The lower end of the rotating connecting arm 200 is assembled and connected to the rotating bearing seat 103, and has a locked state and an unlocked state. The specific structure can be: the lower end of the rotating connecting arm 200 is assembled on the connecting column 105, and the locking state and the unlocking state are switched by the locking member 106. Figure 2-4The lower end of the rotating connecting arm 200 is provided with a rotating clamping position 201, and the rotating clamping position 201 is assembled on the connecting column 105, so that the rotating connecting arm 200 can rotate around the connecting column 105, and the connecting column 105 and the seat cushion 101 are driven to move downward synchronously through the locking member 106, and work together with the bearing 104 to clamp the rotating connecting arm 200 and switch it to a locked state.

[0045] When the photographic device described in the embodiment of the present invention is in use, the user can lock the rotating connecting arm 200 (that is, the rotating connecting arm 200 is in a locked state) by operating the locking member 106. At this time, the rotating connecting arm 200 rotates together with the seat cushion 101, driving the photographic equipment 400 such as the camera installed on the rotating connecting arm 200 to rotate synchronously, thereby realizing rotational shooting. There is no need to rotate the photographic equipment separately, which makes the shooting operation more convenient, improves the movement stability of the photographic equipment 400 during the rotational shooting process, and ensures that the relative position between the user and the photographic equipment 400 remains unchanged, thereby improving the photography quality and the capture efficiency of the photographic lens (quickly capturing the photographic image), and can also ensure the safety of the user during the rotational photography process, reduce fatigue, and improve comfort.

[0046] Moreover, the user can unlock the rotatable connecting arm 200 (the rotatable connecting arm 200 is in the unlocked state) by operating the locking member 106 according to the actual shooting environment and shooting requirements. The rotatable connecting arm 200 can rotate around the seat cushion 101 and adjust its relative position with the seat cushion 101 (such as Figure 1 , 4, 5, 7, 10), which expands the scope of application of the photographic device and makes it more flexible and convenient to use.

[0047] Preferably, the rotational latch 201 is a U-shaped latch provided at the lower end of the rotational connecting arm 200. The U-shaped latch is directly engaged with the connecting post 105, and then the locking member 106 is tightened to complete the assembly of the rotational connecting arm 200 and the seat portion 100. This operation is simple, convenient, and quick. Furthermore, by adjusting the distance between the U-shaped latch and the connecting post 105, the distance between the rotational connecting arm 200 and the seat cushion 101 can be adjusted to suit the requirements of different users, further enhancing the flexibility of the photographic device.

[0048] More preferably, the lower end of the U-shaped bayonet extends inwardly to form a convex edge 202, so that the diameter of the lower end of the U-shaped bayonet is smaller than the outer diameter of the connecting column 105. When in the locked state, the convex edge 202 is clamped between the connecting column 105 and the bearing 104. Figure 3 The stability and firmness of the rotating connecting arm 200 are further improved.

[0049] like Figure 3 As shown, in order to further improve the assembly convenience and stability, the upper surface of the bearing 104 in Examples 1 and 2 of the present invention is provided with a groove 115, and the lower end of the connecting column 105 is provided with a connecting portion 107, and the connecting portion 107 is coaxial with the connecting column 105.

[0050] Furthermore, the locking member 106 is further provided with a spring 116, the two ends of which respectively abut against the locking member 106 and the bearing 104. The spring 116 generates an upward force on the locking member 106, thereby improving the unlocking performance of the locking member 106.

[0051] like Figure 1, as shown in 4-12, the photographic device described in Examples 1 and 2 of the present invention also includes a photographic boom 300. When the rotating connecting arm 200 is rotated and adjusted to the left or right side of the seat cushion 101, the upper end of the rotating connecting arm 200 can be installed with the photographic boom 300, and the photographic boom 300 has a photographic equipment mounting seat 313. The photographic equipment mounting seat 313 is used to install the photographic equipment 400. For example, the photographic equipment mounting seat 313 can be a photographic camera screw, which is used to directly install a photographic camera or install a pan head and then install a photographic camera. The photographic equipment mounting seat 313 can also be a quick-release clip, which is used to directly install a photographic camera. The photographic crane arm 300 includes a first crane arm 303, a second crane arm 304, and a third crane arm 305. The first crane arm 303 is assembled on the upper end of the rotating connecting arm 200. The second crane arm 304 is arranged horizontally, with one end connected to the front end of the first crane arm 303 and the other end provided with a photographic equipment mounting seat 313. In order to make the photographic crane arm 300 suitable for being assembled on the rotating connecting arm 200 that rotates to the left and right sides of the seat cushion 101, the front end of the first crane arm 303 is provided with an upper mounting seat 301 and a lower mounting seat 302 so that Assembled and connected with the second boom 304, the upper mounting seat 301 and the lower mounting seat 302 can be connecting seats provided with internal threaded holes, and the second boom 304 is assembled to the front end of the first boom 303 by a screw; one end of the third boom 305 is connected to the rear end of the first boom 303, and is provided with a counterweight 306, and the counterweight 306 includes a counterweight block 307 and a connecting rod 308, and the counterweight block 307 is provided at the rear end of the connecting rod 308, and the front end of the connecting rod 308 can be telescopically and lockedly inserted into the rear end of the first boom 303.

[0052] Furthermore, the second arm 304 is rotatably connected to the first arm 303, while the third arm 305 is axially folded and connected to the first arm 303. Specifically, one end of the second arm 304 is laterally rotatably connected to the front end of the first arm 303, while the front end of the third arm 305 is upwardly folded and folded to the rear end of the first arm 303. When not in use, the second arm 304 is rotated to be aligned with the first arm 303 (or alternatively, to overlap the first arm 303), and the third arm 305 is axially flipped to overlap the first and second arms 303, 304. This significantly reduces the size and space occupied by the photography boom 300, reducing packaging and shipping costs while also facilitating storage and portability. In addition, in order to improve the folding effect, a folding connection part 309 is provided between the front end of the third boom 305 and the rear end of the first boom 303, and the two ends of the folding connection part 309 are rotatably connected to the third boom 305 and the first boom 303 respectively; and the rear end of the first boom 303 and the front end of the third boom 305 are respectively provided with a first avoidance position 310 and a second avoidance position 311, so that the rear end of the first boom 303 and the third boom 305 are folded more closely; the folding connection part 309 is also provided with a positioning protrusion 312, which limits the expansion angle between the first boom 303 and the third boom 305, so as to ensure the counterweight performance on the third boom 305.

[0053] For example Figure 10-12 As shown, the photographic boom 300 described in the second embodiment of the present invention is rotatably mounted on the upper end of the rotating connecting arm 200 (specifically, the first boom 303 of the photographic boom 300 is rotatably mounted on the upper end 315 of the longitudinal connecting arm 207 of the rotating connecting arm 200 via a rotating shaft 314), and an angle adjustment structure is provided therebetween. The angle adjustment structure includes a turntable 203 and a quick-lock bolt 315. The turntable 203 is mounted on the upper end of the rotating connecting arm 200 and is provided with arc-shaped or annular locking positions 204. The quick-lock bolt 315 is laterally and axially movable mounted on the photographic boom 300. When the angle of the photographic boom 300 is adjusted, the quick-lock bolt 315 can be pulled away from the turntable 203 until its inner end is separated from the locking position 204. After the angle adjustment of the photographic boom 300 is completed, the quick-lock bolt 315 can automatically return to the direction of the turntable 203 until its inner end is separated from the corresponding locking position 204. The angle adjustment structure can be used to adjust the pitch angle of the photographic boom 300, thereby adjusting the shooting angle of the photographic device 400. Compared with the existing angle adjustment structure that requires repeatedly turning the screw, the adjustment operation is convenient and quick.

[0054] Preferably, the outer end of the quick-lock bolt 315 has an operating part 316, and the operating part 316 is provided with a locking bayonet 317. When the quick-lock bolt 315 can automatically reset and move toward its inner end and the corresponding locking position 204 in the direction of the turntable 203, the locking bayonet 317 clamps the photographic crane 300, avoiding the risk of the quick-lock bolt 315 and the locking position 204 being accidentally loosened, and the use safety is high.

[0055] like Figure 1 , 4, 6, and 10, the upper end of the rotating connecting arm 200 described in the first and second embodiments of the present invention is further provided with a first connector 205, and the first connector 205 can be used to install the photographic equipment 400. For example, the first connector 205 can be a camera screw for directly installing a photographic camera or installing a pan / tilt head and then installing a photographic camera. The first connector 205 can also be a quick-release clip for directly installing a photographic camera.

[0056] The seat cushion 101 is connected to a backrest 108, which is detachable from the seat cushion 101. The first connector 205 can also be assembled with the backrest 108 detached from the seat cushion 101 to form a workbench. Specifically, the seat cushion 101 has a first clamping portion 110 at the rear end, which has two left and right clamping holes 111. The backrest 108 has a second clamping portion 112 at the lower end, which has two left and right telescopic clamping posts 113, which are detachably assembled into the two clamping holes 111. The back of the backrest 108 has a second connector 114, which is assembled with the first connector 205 to form a workbench. This allows users to complete operations such as assembling the photographic equipment 400 on the workbench, reducing the risk of the equipment falling while being assembled, improving the convenience and safety of the assembly, and eliminating the need for an additional workbench, making it more convenient to carry and store.

[0057] like Figure 1 , 5-7, 10, 11, the upper end of the longitudinal connecting arm 207 of the first and second embodiments of the present invention has a telescopic arm 208, and the user can adjust the height of the telescopic arm 208 as needed, thereby adjusting the shooting height of the photographic equipment 400 or adjusting the height of the workbench formed by the backrest 108; the specific structure can be: the upper end of the longitudinal connecting arm 207 is provided with a socket (not shown in the figure), the lower end of the telescopic arm 208 is movably installed in the socket, and the outer wall of the upper end of the longitudinal connecting arm 207 is also provided with a locking screw 209, one end of the locking screw 209 passes through the outer wall of the longitudinal connecting arm 207, extends into the socket, and abuts against the telescopic arm 208 to lock the telescopic arm 208.

[0058] Furthermore, a locking pressure plate 210 is provided at the abutting end of the locking screw 209 , which improves the locking performance of the telescopic arm 208 on the one hand, and prevents the telescopic arm 208 from being crushed or scratched on the other hand.

[0059] like Figure 1-5 , 7, 9, and 10, the leg portion 102 of the first and second embodiments of the present invention further includes three supporting legs 109. The three supporting legs 109 are arranged in a circular array and assembled on the rotating bearing seat 103. The upper ends of the three supporting legs 109 are connected to the rotating bearing seat 103 so as to be rotatable up and down. When in use, the three supporting legs 109 are in an unfolded supporting state, and when not in use, the three supporting legs 109 are in a folded state. In this way, the photographic device is easy to carry and more convenient to use outdoors. Example 3

[0060] like Figure 13 and 14 As shown, the photographic device of Embodiment 3 of the present invention has a structure substantially similar to that of Embodiments 1 and 2, comprising a seat portion 100 and a rotating connecting arm 200. The only difference is that the photographic device includes two or more upper rotating connecting arms 200, at least one of which is mounted with the photographic boom 300 at its upper end, and at least one of which is provided with a first connector 205 at its upper end.
