When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0041] The utility model proposes an expansion bracket 100, which is used to detachably install a camera auxiliary device in front of a camera lens of a camera device. In this embodiment, the camera device is a device with a camera lens, which can be a camera or a mobile phone, etc.; the camera auxiliary device can be a filter or a sunshade, etc., wherein the filter, as one of the commonly used camera auxiliary devices, can be used to intercept ultraviolet rays, protect the lens and improve the photographic effect; the filter can be a UV (ultraviolet) filter, a skylight filter, a polarizing filter, a gray filter (ND), a fogging filter, etc., which can be selected according to the application environment, imaging requirements, etc. to meet people's different needs for shooting; when the camera auxiliary device is a sunshade, it can block the light leakage area to achieve the purpose of anti-glare.

[0042] Please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the expansion bracket 100 includes a bearing body 10, the bearing body 10 is used for detachably installing the camera auxiliary device, and the bearing body 10 is formed with a light-transmitting portion 11 for light to pass through.

[0043] In this embodiment, the light-transmitting portion 11 is located in front of the camera lens for light to pass through, and the camera auxiliary device is installed at the light-transmitting portion 11. When the camera auxiliary device is a filter, it can be used to filter light, such as to eliminate the influence of ultraviolet rays and stray light in natural light on the photosensitivity of the film, and at the same time protect the camera lens.

[0044] Among them, the detachable installation method can be a snap connection, a threaded connection, a magnetic connection, etc., which is convenient for disassembling and installing the camera auxiliary device and the carrier body 10.

[0045] The expansion bracket 100 further includes at least two connecting arms 20, which are spaced apart and distributed around the outer periphery of the carrying body 10, and one end of the at least two connecting arms 20 is respectively connected to the carrying body 10, and at least two connecting arms 20 are provided with a first connecting hole 21, and the first connecting hole 21 is used for fasteners 30 to pass through to detachably connect the camera device. The fasteners 30 may be screws with nuts, but are not limited thereto.

[0046] In this embodiment, at least two first connection holes 21 can be pierced by fasteners 30 to detachably connect the camera device, and the supporting body 10 and the camera auxiliary device can be detachably installed, so that the expansion bracket 100 of the utility model can achieve structural modularization. Users can disassemble or install it according to usage requirements, and the assembly is convenient. Moreover, the installation position of each module can be flexibly adjusted, and the compatibility and adaptability are strong.

[0047] In some embodiments, the first connection hole 21 is a sliding hole 22 in which the fastener 30 can slide, and the sliding hole 22 is extended along the length direction of the connection arm 20. In this embodiment, by moving the connection arm 20 to allow the fastener 30 to slide in the sliding hole 22, the position adjustment of the supporting body 10 relative to the camera device is achieved, that is, the position adjustment of the camera auxiliary device relative to the camera device is adjusted, which can be applicable to camera devices of different sizes and positions, has good compatibility and adaptability, and is convenient and flexible to adjust, thereby improving the shooting effect, facilitating user use, and improving user experience.

[0048] In some embodiments, the number of the connecting arms 20 is two, and the two connecting arms 20 are distributed in an eight-shaped pattern at intervals on the outer periphery of the carrying body 10. Correspondingly, two fasteners 30 are provided, and each fastener 30 cooperates with a first connecting hole 21. Among them, each fastener 30 can be used as a rotation fulcrum, so that the carrying body 10 can rotate with one of the fasteners 30 as a fulcrum, and the other fastener 30 slides in the corresponding first connecting hole 21, so as to realize the left-right and up-down sliding of the carrying body 10 relative to the camera device, thereby realizing the position adjustment between the camera auxiliary device and the camera device, and the operation is convenient and quick.

[0049] Of course, the adjustment can also be performed without using the fastener 30 as the rotation fulcrum. For example, the two fasteners 30 can be loosened at the same time, and the connecting arm 20 can be driven to slide along the fastener 30 by pulling the load-bearing body 10. After the load-bearing body 10 reaches the preset position, the two fasteners 30 can be tightened at the same time to complete the position adjustment of the load-bearing body 10.

[0050] The position adjustment method for the bearing body 10 of the utility model is simple and flexible to operate, easy to implement, convenient for users to use, and improves user experience.

[0051] In some embodiments, the light-transmitting portion 11 is a through hole 12 that penetrates the carrier body 10, which saves structural materials and has low cost.
