And, the lower side of the first arm 31 is provided with a boss 315. The boss 315 is used for connecting with an external support frame. It can be appreciated that boss 315 defines a screw hole for connection to a tripod. Moreover, the boss 315 is disposed at the middle of the hollow-out groove 314, so that the position of the boss 315 can be as close to or coincident with the center of gravity of the ring-shaped flash assembly 1 as possible. Therefore, when a tripod is supported and connected to the ring flash assembly 1 through the boss 315, the connecting position of the tripod and the boss 315 is also approximate to the center of gravity of the ring flash assembly 1, and it is possible to ensure that the assembly of the ring flash 2 is stable and prevented from tilting, shaking, and the like.

The second arm 32 is slidably connected to an end of the first arm 31 to allow the second arm 32 to slide along the first arm 31. Specifically, the left side of the first arm 31 is provided with a slot 316, and the second arm 32 can be slidably inserted into the slot 316.

The bracket 3 of the present embodiment further includes a second fastener 35. A second fastener 35 is provided at one end of the first arm 31. The second fastening member 35 is correspondingly connected to the slot 316. The second arm 32 defines a second adjustment slot 321. The second fastener 35 is inserted into the second adjusting groove 321, and the second arm 32 is adjusted relative to the first arm 31 and fastened by the second fastener 35. The second arm 32 moves telescopically toward the first arm 31 and the second arm 32 moves in the Y-axis direction.

And, the second fastening member 35 is a fastening bolt. The stud of the second fastener 35 passes through the slot 316, and a screw hole is formed at the corresponding position of the first arm 31, and the screw hole can be in threaded connection with the stud of the first arm 31. And, the nut 352 of the second fastener 35 is located outside the first arm 31. When the second fastener 35 locks the first arm 31 and the second arm 32, the bolt 351 of the second fastener 35 passes through the second adjustment slot 321 to be screwed with the first arm 31. When the second fastener 35 is tightened, the nut 352 may press and fix the second arm 32 by a washer (not shown) to lock the relative position between the first arm 31 and the second arm 32.

In other embodiments, the second adjustment groove 321 may also be omitted. The second fastener 35 may be directly held against the second arm 32. As long as a sufficiently large clamping force between the second fastener 35 and the second arm 32 is ensured.

The third arm 33 is used for being fixedly connected with the ring-shaped flash lamp 2. When the third arm 33 and the second arm 32 are perpendicular to each other, the third arm 33 is located in the Z-axis direction. Therefore, the position of the ring flash 2 and the third arm 33 is adjusted, so that the position adjustment of the ring flash 2 in the Z-axis direction can be realized.

Specifically, a limit baffle 221 is disposed on the outer side surface of the base 22 of the ring-shaped flashlight 2. The limit baffle 221 abuts against the side edge of the third arm 33, so that the third arm 33 can stably support the ring-shaped flashlight 2. The limit stop 221 is located on the left side of the base 22 of the ring flash 2. The connecting position of the third arm 33 to the ring flash 2 is located on the left side of the ring flash 2. Moreover, the limit stop 221 is located at the left side of the third arm 33, so that the limit stop 221 can increase the acting surface between the third arm 33 and the ring flash 2, and the limit stop 221 can provide a right supporting force to the third arm 33, which helps the ring flash 2 to be supported in a balanced manner.

One or more guide baffles 222 are also arranged on the base 22 of the ring flash 2. The guide fence 222 is disposed opposite to the limit fence 221. A guide channel for receiving the third arm 33 is formed between the guide fence 222 and the limit fence 221. When the connecting position of the annular flash lamp 2 on the third support arm 33 is adjusted, the third support arm 33 moves in the guide channel, so that the position of the annular flash lamp 2 only moves along the direction of the third support arm 33, the third support arm 33 is prevented from being twisted, and the accuracy of adjusting the position of the annular flash lamp 2 is reduced.

The circular hole of the ring flash 2 is located on the right side of the third arm 33. The axis of the ring flash 2 mounted on the bracket 3 intersects the first arm 31. Therefore, the photographing apparatus mounted on the stand 3 is also positioned at the right side of the third arm 33. Under the normal condition, the right side of the photographic equipment is the operation side, and the bracket 3 can not occupy the right space of the photographic equipment, so that the phenomenon that the operation button of the photographic equipment is shielded to influence the convenient operation of the photographic equipment is avoided.

In this embodiment, the stand 3 further includes a third fastening member 36 for connecting with the camera device. The third arm 33 is provided with a third adjusting hole 331. The third fastener 36 is slidably disposed within the third adjustment aperture 331. Wherein, the third fastener 36 is detachably connected with the ring flash 2, so that the ring flash assembly 1 can be conveniently assembled and stored.

It is understood that the third fastener 36 is a fastening screw. The third fastener 36 may be threaded with the ring flash 2. Alternatively, the third fastening member 36 may be a snap fastening member, and the third fastening member 36 and the ring flash 2 may be snap-fit connected. Here, the specific structure and kind of the third fastening member 36 are not limited as long as the third fastening member 36 can be stably and detachably connected to the ring flash 2.

Specifically, in the present embodiment, the third arm 33 and the second arm 32 are rotatably connected at an end away from the first arm 31, so as to adjust an included angle of the third arm 33 relative to a plane where the first arm 31 and the second arm 32 are located. Here, since the first arm 31 and the second arm 32 both have a certain thickness, the first arm 31 and the second arm 32 can be approximately located in the same plane. When the irradiation angle of the ring flash 2 on the third arm 33 needs to be adjusted, the third arm 33 can be rotated, so that the light angle of the ring flash 2 is changed.

The above-mentioned support 3 also comprises a spindle 37. The second arm 32 has a first turn disc 322 at one end. The plane of the first rotary plate 322 is perpendicular to the plane of the second arm 32.

One end of the third arm 33 is provided with a second rotating disk 333. The plane of the second rotating disk 333 is perpendicular to the plane of the third arm 33. The first and second

rotatable disks

322 and 333 are parallel to each other. The rotating shaft 37 passes through the second rotating disc 333 and is fixedly connected with the first rotating disc 322, and the second rotating disc 333 is rotatably arranged on the rotating shaft 37.

Therefore, the second rotating disc 333 rotates around the rotating shaft 37, so that the included angle of the third arm 33 with respect to the plane where the first arm 31 and the second arm 32 are located, that is, the pitch angle of the ring flash 2 can be adjusted.

Specifically, in the present embodiment, a limiting structure 38 is disposed between the first rotating disk 322 and the second rotating disk 333. The first rotary disk 322 and the second rotary disk 333 are rotated relatively to each other. A spacing structure may define the relative position between the first dial 322 and the second dial 333.

Specifically, the limiting structure 38 includes a plurality of protrusions 381 and a corresponding slot 382 engaged with the protrusions 381. The protrusion 381 is engaged with the slot to limit the first rotary plate 322 and the second rotary plate 333. It is understood that the protrusion 381 and the locking groove 382 may be engaged with each other, and the installation position of the protrusion 381 and the installation position of the locking groove 382 are not limited herein.

In this embodiment, the protrusions 381 are uniformly distributed on the second rotating disk 333. Accordingly, the plurality of card slots 382 are evenly distributed on the first turntable 322. Specifically, the projections 381 may be four. There are also four card slots 382. It is understood that the number of the protrusions 381 and the card slots 382 may be other numbers, such as 6, 8, etc. The number of the protrusions 381 and the locking grooves 382 is not limited, and the protrusions 381 and the locking grooves 382 may be designed accordingly according to the adjustment accuracy required by the pitch angle of the ring flash 2.

The projection 381 is a rib. The axial direction of the projection 381 extends in the radial direction of the second rotating disk 333. Thus, the four protrusions 381 correspond to 0 degrees, 90 degrees, 180 degrees, and 270 degrees of the turntable, respectively. By rotating the second rotary plate 333, the pitch angles of the ring flash 2 at 0 degrees, 90 degrees, 180 degrees, and 270 degrees can be adjusted.

Referring to fig. 3-5, fig. 3 shows the status of the bracket when the ring flash 2 is at a pitch angle of 90 degrees. Fig. 4 shows the state of the stand when the ring flash 2 is at a pitch angle of 180 degrees. Fig. 5 shows the state of the stand when the ring flash 2 is at a pitch angle of 0 degrees.

Referring to fig. 6, the surface of the protrusion 381 has a cut 383. Cut 383 ensures a stable contact between protrusion 381 and slot 382. In addition, the cross section of the protrusion 381 is trapezoidal or wedge-shaped, so that the protrusion 381 can be smoothly clamped into the clamping groove 382.

One end of the rotating shaft 37 is threadedly coupled to the first rotating disk 322. The other end of the rotating shaft 37 is provided with a knob 371. The spacing structure 38 also comprises a metallic spacer 39. A gasket 39 is arranged between the knob 371 of the rotating shaft 37 and the second rotating disc 333 to increase the force-bearing area between the knob 371 and the second rotating disc 333, and the metal gasket 39 can ensure that the rotating shaft 37 can stably clamp the first rotating disc 322 and the second rotating disc 333 and ensure the position stability of the third support arm 33 and the second support arm 32.

In other embodiments, the limiting structure 38 further comprises an elastic member (not shown). The elastic member abuts between the knob and the second rotating disc 333.

When the pitch angle of the ring flash 2 needs to be adjusted, the protrusion 381 of the second rotary disk 333 is firstly separated from the slot 382 of the first rotary disk 322, and the second rotary disk 333 needs to be moved axially outward along the rotary shaft 37 relative to the first rotary disk 322. The elastic member is compressed while the second rotating disk 333 is moved outward, so that the elastic member is elastically deformed. Then, the third support arm 33 is rotated to rotate the second rotating disc 333 relative to the first rotating disc 322, and when the second rotating disc 333 is adjusted to a proper angle, only the second rotating disc 333 needs to be loosened, the elastic member recovers elastic deformation, the second rotating disc 333 moves towards the first rotating disc 322, so that the protrusion 381 is clamped into the clamping groove 382, and the clamping limit connection between the first rotating disc 322 and the second rotating disc 333 is recovered. It is understood that the elastic member may be a rubber gasket, a spring, or the like.

The ring flash unit 1 can support and fix the ring flash 2 by the first arm 31, the second arm 32 and the third arm 33 of the bracket 3. Moreover, the bracket 3 can fix and adjust the position of the photographic equipment and also can fix and adjust the position of the ring-shaped flash lamp 2. In addition, the three-dimensional position adjustment can be realized through the matching of the first support arm 31, the second support arm 32 and the third support arm 33, and meanwhile, the pitch angle of the annular flash lamp 2 can also be adjusted. Therefore, when the annular flash lamp 2 is fixed by using the support 3, the holding by an operator can be avoided, and the convenience of the annular flash lamp 2 is improved.

Moreover, when the ring flash 2 or the photographing apparatus is replaced, the adjustment can be facilitated by the cooperation among the first arm 31, the second arm 32, and the third arm 33.

Moreover, the photographing device is arranged on the first supporting arm 31, the bracket 3 is arranged to only occupy the left space of the photographing device, the right control space of the photographing device is not occupied, the bracket 3 does not shield the control button of the photographing device, and the photographing device can be conveniently operated and used.
