[0034] First see Figure 1 The utility model provides a photographic stand 1 for supporting a photographing device to prevent the photographing device from shaking and affecting the photographing effect when the user is using the photographing device. By using the photographic stand 1 to shoot, the user can obtain the desired photographic effect. The photographic stand 1 is used in conjunction with the photographing device to shoot, which can adapt to a variety of usage scenarios. The photographic stand 1 can be unfolded in a variety of usage scenarios, and the user can switch between different usage modes according to usage requirements, and the user experience is good.

[0035] It should be noted that the shooting equipment is electronic devices such as mobile phones and cameras.

[0036] Continue to refer Figure 1 The photographic bracket 1 includes a clamp 10 and a gimbal 20. The clamp 10 can be clamped on a clamped object or placed on a supporting surface. The gimbal 20 is respectively connected to the clamp 10 and the photographic device to fix the photographic device on the clamp 10. When the photographic device is installed on the gimbal 20, the user can use the photographic bracket 1 to take pictures and obtain the photographic effect the user wants.

[0037] It should be noted that the clamping object is an object that can be clamped, and the clamping object can be an object such as a wooden board, a pillar, etc.; the supporting surface is a position where the photographic bracket 1 is fixed, and the supporting surface can be a photographic position such as a desktop, the ground, etc.

[0038] It can be understood that in other embodiments, the pan head 20 can be omitted, and the photographic bracket 1 only includes the clamp 10 .

[0039] refer to Figure 2The powerful clamp 10 includes a first clamp arm 100, a second clamp arm 200, a first connecting rod 400 and a second connecting rod 500. One end of the second clamp arm 200 is rotatably connected to the first clamp arm 100. Both axial ends of the first connecting rod 400 and the second connecting rod 500 are connected to the first clamp arm 100 and the main body 300. The axial ends of the first connecting rod 400 and the second connecting rod 500 can be swung and adjusted relative to the first clamp arm 100 and the main body 300. The first clamp arm 100 and the second clamp arm 200 form a powerful clamp with a jaw 110. At this time, by screwing the first connecting rod 400 and the second connecting rod 500, the angle between the first clamp arm 100 and the second clamp arm 200 can be adjusted to adapt to the size of the clamped object, so that the powerful clamp 10 can be clamped on the clamped object. Then, the shooting equipment is installed on the powerful clamp 10 to take pictures.

[0040] It should be noted that the above-mentioned pan / tilt head 20 is connected to the rotationally connected portion of the first clamping arm 100 or the second clamping arm 200 .

[0041] refer to Figure 2 and Figure 3 The second clamp arm 200 includes a main body 300 and a first arm 210 and a second arm 220 that can be folded and unfolded. One end of the main body 300 is rotatably connected to the first clamp arm 210, and the other end is used for rotatably connecting the first arm 210 and the second arm 220. When the strong clamp 10 is in the strong clamp state with the jaws 110, the first arm 210 and the second arm 220 are in the folded state ( Figure 2 When the first arm 210 and the second arm 220 are unfolded relative to the main body 300, the first link 400 and the second link 500 lock the first clamp arm 210 and the second clamp arm 220, and the first clamp arm 100, the first arm 210 and the second arm 220 constitute a tripod ( Figure 3 As shown), at this time, the powerful clamp 10 can be directly placed on the support surface to support and cooperate with the shooting equipment for shooting.

[0042] To summarize, in the present application, when the first arm 210 and the second arm 220 are folded, the first clamp arm 100 and the second clamp arm 200 form a strong clamp with jaws, which can be clamped on the clamped object; when the first arm 210 and the second arm 220 are unfolded, the first clamp arm 100, the first arm 210 and the second arm 220 form a tripod. When there is no clamped object in the shooting environment, the strong clamp 10 can be placed on a supporting surface for shooting. It is easy to use and can adapt to more usage environments.

[0043] refer to Figure 2 and Figure 3It should be noted that the two sides of the main body 300 are rotatably connected to the first arm 210 and the second arm 220 respectively, and the first connecting rod 400 and the second connecting rod 500 can be extended or shortened relative to the first clamping arm 100 to adjust the maximum angle between the first clamping arm 100 and the second clamping arm 200, thereby adjusting the maximum opening size of the jaws 110; and a swing notch 120 is provided on the side of the first clamping arm 100 close to the main body 300. When the maximum angle between the first clamping arm 100 and the second clamping arm 200 is adjusted, the first connecting rod 400 and the second connecting rod 500 swing in the corresponding swing notch 120 respectively, and when the first connecting rod 400 abuts against the side wall of the swing notch 120, the swing of the first connecting rod 400 relative to the first clamping arm 100 is restricted, and when the second connecting rod 500 abuts against the side wall of the swing notch 120, the swing of the second connecting rod 500 relative to the first clamping arm 100 is restricted. By using the first connecting rod 400 and the second connecting rod 500, the maximum angle between the first clamp arm 100 and the second clamp arm 200 can be precisely adjusted by twisting the first connecting rod 400 and the second connecting rod 500, unlike other connection methods such as clamping, which can only be fixed in one position and cannot precisely adjust the maximum angle between the first clamp arm 100 and the second clamp arm 200. It should be noted that the main body 300 includes a connecting portion 310 and an extending portion 320 connected to each other, the connecting portion 310 is connected to the first clamp arm 100, and the axial opposite ends of the first connecting rod 400 are connected to the connecting portion 310 and the first clamp arm 100.

[0044] Continue to refer Figure 2 and Figure 3 The second connecting rod 500 is spaced apart from the first connecting rod 400 , and an included angle between an extending direction of the first connecting rod 400 and an extending direction of the second connecting rod 500 is less than 90°.

[0045] It should be noted that two opposite axial ends of the second connecting rod 500 are connected to the extending portion 320 and the first clamping arm 100 .

[0046] refer to Figure 4The first connecting rod 400 includes a first rod body 410 and a second rod body 420. The first rod body 410 is sleeved on the second rod body 420. One end of the first rod body 410 is connected to the first clamp arm 100, and the other end of the first rod body 410 is threadedly connected to the second rod body 420. The second rod body 420 is inserted into the main body 300. The part of the second rod body 420 that passes through the main body 300 and is away from the first rod body 410 is provided with a knob 430. The user can turn the knob 430 to extend or shorten the distance between the first rod body 410 and the second rod body 420, thereby adjusting the maximum angle between the first clamp arm 100 and the second clamp arm 200. It can be understood that the first rod body 410 and the second rod body 420 may not be provided. As long as the first rod body 410 can be extended or shortened relative to the first clamp arm 100 to adjust the maximum angle between the first clamp arm 100 and the second clamp arm 200, all solutions should be protected.

[0047] It should be noted that, in other embodiments, the first connecting rod 400 further includes an elastic member, and the opposite ends of the elastic member are elastically abutted against the first rod body 410 and the second rod body 420, respectively. When the knob 430 is turned, the second rod body 420 rotates relative to the first rod body 410 and approaches the first clamp arm 100, and the second rod body 420 compresses the elastic member to accumulate elastic force. When the user loosens the knob 430 in the opposite direction, the elastic force is released, and the elastic member can push the main body 300 to move in a direction away from the first clamp arm 100, and the maximum angle between the first clamp arm 100 and the second clamp arm 200 increases. It can be understood that the elastic member may not be provided, and any solution that can adjust the maximum angle between the first clamp arm 100 and the second clamp arm 200 should be protected.

[0048] It should be noted that the configuration of the second connecting rod 500 is the same as the configuration of the first connecting rod 400 described above, and the present invention will not elaborate on the specific configuration of the second connecting rod 500 in detail.

[0049] refer to Figure 5 , the first arm 210 and the second arm 220 are both provided with a groove 230 on one side close to the main body 300. When the first arm 210 and the second arm 220 are folded, the two grooves 230 enclose and form an installation space 240, and the extension 320 is accommodated in the installation space 240. The main body 300 will not hinder the storage of the first arm 210 and the second arm 220. The first arm 210 and the second arm 220 can be close to each other, which can reduce the overall volume of the clamp 10, reduce the consumables of the first arm 210 and the second arm 220, and increase the contact area between the clamp 10 and the clamped object, and increase the clamping force of the clamp 10 to clamp the clamped object. It can be understood that, without considering reducing consumables and increasing clamping stability, the groove 230 may not be provided, as long as the first arm 210 and the second arm 220 can be unfolded or folded relative to the main body 300, all solutions should be protected.

[0050] refer to Figure 3 and Figure 5 The first arm 210 is provided with a limiting protrusion 211 toward the side wall of the extension portion 320 and one of the side walls of the extension portion 320, and the other side wall is provided with a limiting groove 321, for example Figure 5 As shown, the first arm 210 is provided with a limiting protrusion 211, and the extension portion 320 is provided with a limiting groove 321. When the first arm 210 and the second arm 220 are folded, the limiting protrusion 211 is buckled in the limiting groove 321, and the limiting protrusion 211 is clamped in the limiting groove 321, so that the first arm 210 will not rotate relative to the main body 300 when it is in the folded state. It should be noted that in other embodiments, the setting positions of the limiting protrusion 211 and the limiting groove 321 can be reversed. In this case, the limiting protrusion 211 is set on the extension portion 320, and the limiting groove 321 is set on the first arm 210. It can be understood that both the limiting protrusion 211 and the limiting groove 321 can be not set, as long as the solution that the first arm 210 will not rotate relative to the main body 300 when it is in the folded state should be protected.

[0051] It should be noted that the second arm 220 is arranged in the same manner as the first arm 210. In this embodiment, the first arm 210 and the second arm 220 are provided with a limiting protrusion 211 on the side wall facing the extension portion 320, and the side wall of the extension portion 320 is provided with a limiting groove 321.

[0052] It should be noted that by setting the limiting protrusion 211 and the limiting groove 321, the first arm 210 and the second arm 220 will not rotate relative to the main body 300, and the main body 300, the first arm 210 and the second arm 220 together form the second clamp arm 200. At this time, the first clamp arm 100 and the second clamp arm 200 can both be stably placed on the support surface. The user can hold the power clamp 10 to act as a gimbal stabilizer or place it on the support surface to act as an upright gimbal stand, which can adapt to more usage environments.

[0053] It should be noted that, in other embodiments, a limiting protrusion 211 is provided on the side wall of the first arm 210 toward the extension portion 320, and a limiting groove 321 is provided on the side wall of the extension portion 320 toward the first arm 210; a limiting groove 321 is provided on the side wall of the second arm 220 toward the extension portion 320, and a limiting protrusion 211 is provided on the side wall of the extension portion 320 toward the second arm 220.

[0054] It should be noted that in other embodiments, a limiting groove 321 is provided on the side wall of the first arm 210 facing the extension portion 320, and a limiting protrusion 211 is provided on the side wall of the extension portion 320 facing the first arm 210; a limiting protrusion 211 is provided on the side wall of the second arm 220 facing the extension portion 320, and a limiting groove 321 is provided on the side wall of the extension portion 320 facing the second arm 220.

[0055] It should be noted that in other embodiments, the first arm 210 and the second arm 220 are provided with limiting grooves 321 on the side walls facing the extension portion 320 , and the side walls of the extension portion 320 are both provided with limiting protrusions 211 .

[0056] refer to Figure 3 The first clamp arm 100 is provided with a first mounting seat 130 at one end close to the opening of the jaw 110, and the first mounting seat 130 is rotatably connected to the first clamp arm 100. The first support arm 210 is provided with a second mounting seat 212 at one end close to the opening of the jaw 110, and the second mounting seat 212 is rotatably connected to the first support arm 210. The second support arm 220 is provided with a third mounting seat 221 at one end close to the opening of the jaw 110, and the third mounting seat 221 is rotatably connected to the second support arm 220. The first mounting seat 130, the second mounting seat 212 and the third mounting seat 221 support the powerful clamp 10 on the support surface. The contact area between the first mounting seat 130, the second mounting seat 212 and the third mounting seat 221 and the support surface is larger than the contact area between the first clamp arm 100, the first support arm 210 and the second support arm 220 and the support surface. The powerful clamp 10 in the tripod state can be placed on the support surface more stably, which can ensure that the powerful clamp 10 will not fall due to unstable support during shooting. Moreover, the first mounting seat 130 is rotatably connected to the first clamp arm 100, the second mounting seat 212 is rotatably connected to the first support arm 210, and the third mounting seat 221 is rotatably connected to the second support arm 220. No matter the powerful clamp 10 is in the powerful clamp state or in the tripod state, by rotating the angles of the first mounting seat 130, the second mounting seat 212 and the third mounting seat 221, it can be ensured that the first mounting seat 130, the second mounting seat 212 and the third mounting seat 221 can be stably supported on the support surface. It can be understood that, without considering whether the powerful clamp 10 can be stably supported on the support surface, the first mounting seat 130, the second mounting seat 212 and the third mounting seat 221 can all be not provided, and as long as the powerful clamp 10 can form a tripod and can be placed on the support surface, all solutions should be protected.

[0057] Continue to refer Figure 3It should be noted that the first clamp arm 100 forms a depression 140 on the side of the second clamp arm 200, the first arm 210 forms a depression 140 on the side of the first clamp arm 100, and the second arm 220 forms a depression 140 on the side of the first arm 210. When the first arm 210 and the second arm 220 are folded, the depressions 140 on the first clamp arm 100, the first arm 210 and the second arm 220 are combined to form the above-mentioned jaws 110, and the jaws 110 can be clamped on the clamped object. In addition, the depression 140 on the first clamp arm 100 can also be clamped to the upper end of the vertical surface, so that the powerful clamp 10 can be hung on the vertical surface. By setting the powerful clamp 10 to be able to be hung on the vertical surface, the use state of the powerful clamp 10 is increased, and the powerful clamp 10 can adapt to more use environments.

[0058] It should be noted that the vertical surface is the position where the clamp can be hung, such as: a computer screen, a wooden board, and the like support position.

[0059] It should be noted that, in the present embodiment, the powerful clamp 10 further includes a folding plate 700, the first clamp arm 100 is provided with a receiving groove 150, the folding plate 700 is rotatably connected to the first clamp arm 100, so as to extend out or be received in the receiving groove 150, when the folding plate 700 is received in the receiving groove 150, the folding plate 700 is stored, and the folding plate 700 does not affect the use of the powerful clamp 10 in the powerful clamp state and the tripod state; when the folding plate 700 extends out of the receiving groove 150, the folding plate 700 and the first clamp arm 100 form an angle, and clamp the vertical surface together, so that the powerful clamp 10 can be hung on the vertical surface. By setting the powerful clamp 10 to be hung on the vertical surface, the use state of the powerful clamp 10 is increased, and the powerful clamp 10 can adapt to more use environments.

It can be understood that the first surface 610 and the second surface 620 may not be provided with a transfer interface 630. For example, the first surface 610 or the second surface 620 is provided with a transfer interface. As long as the transfer structure 600 is provided with a transfer interface 630, it should be protected.

[0061] When the strong clamp 10 is needed to be used in a strong clamping state, the user folds the first arm 210 and the second arm 220, adjusts the knob 430 on the first link 400 until the size of the jaws 110 is slightly larger than the size of the clamped object, installs the clamped object in the jaws 110, and reversely rotates the knob 430 on the first link 400 until the strong clamp 10 is initially fixed on the fixed object, and then rotates the knob 430 on the second link 500 to further adjust the size of the jaws 110 so that the strong clamp 10 can be clamped on the clamped object more firmly. At this time, the pan head 20 and the shooting equipment are installed on the first surface 610, and the photography bracket 1 can be used for shooting.

[0062] When the tripod clamp 10 is used, the user turns the knob 430 on the first connecting rod 400 so that the first connecting rod 400 abuts against the side wall of the swing notch 120, and then turns the knob 430 on the second connecting rod 500 so that the second connecting rod 500 abuts against the corresponding side wall of the swing notch 120, and then unfolds the first arm 210 and the second arm 220 to a certain unfolding angle, and adjusts the angles of the first mounting seat 130, the second mounting seat 212 and the third mounting seat 221 so that the first mounting seat 130, the second mounting seat 212 and the third mounting seat 221 can be stably placed on the support surface. At this time, the pan head 20 and the shooting equipment are installed on the second surface 620, and the photography bracket 1 can be used for shooting.

[0063] When the clamp 10 needs to be hung on a support surface for use, the user rotates the clamp 10 adjusted to a tripod state to a suitable angle and snaps the recess 140 on the first clamp arm 100 onto the support surface. At this time, the pan / tilt head 20 and the shooting equipment are installed on the first surface 610, and the photography bracket 1 can be used for shooting.
