[0042] Specifically, a curved baffle 2 is sleeved on the top of the camera body 1 .

[0043] A U-shaped support plate 3 is provided at the bottom of the camera body 1, and mounting frames are rotatably sleeved on both sides of the U-shaped support plate 3. Friction pieces are provided at the connection between the mounting frame and the U-shaped support plate 3. The mounting frame can be set at different angles through the extrusion and interlacing of the friction pieces and the U-shaped support plate 3.

[0044] Specifically, the mounting frame includes:

[0045] Connecting rods 4, multiple connecting rods 4 are symmetrically arranged on both sides of the U-shaped support plate 3 along the horizontal direction, and multiple friction members are respectively inserted and connected to the tops of the multiple connecting rods 4;

[0046] The fixing plate 401 is arranged at one end of the plurality of connecting rods 4 away from the U-shaped support plate 3. A plurality of fixing slots 402 are provided in the middle of the fixing plate 401. When making a connection, the entire mounting frame can be fixed by passing bolts through the fixing slots 402.

[0047] Furthermore, adjustment grooves 301 are provided on both sides of the U-shaped support plate 3, and multiple positioning holes 302 are provided on the inner walls on one side of the multiple adjustment grooves 301 in the vertical direction. The friction member adjusts the connection position of the connecting rod 4 by interlacing with different positioning holes 302.

[0048] Specifically, the friction parts include:

[0049] A support rod 5, the support rod 5 is horizontally inserted and connected to the top of the connecting rod 4, and one end of the support rod 5 is slidably inserted and connected to one of the positioning holes 302;

[0050] The friction block 501, a plurality of friction blocks 501 are arranged around one end where the support rod 5 and the positioning hole 302 are inserted, and the plurality of friction blocks 501 and the inner wall of the positioning hole 302 are pressed and inserted into each other.

[0051] Furthermore, the inner walls at the top and bottom ends of the insertion point of the supporting rod 5 and the connecting rod 4 are provided with limiting grooves, and the top and bottom ends of the supporting rod 5 are fixedly connected with limiting sliders 502, and multiple limiting sliders 502 are respectively slidably inserted and connected in multiple limiting grooves, and support springs 6 are provided in multiple limiting grooves.

[0052] It should be noted that the friction block 501 is a rubber strip. This type of structure can deform after being compressed. In this way, the support rod 5 and the friction block 501 are squeezed and inserted into the positioning hole 302 at the corresponding position through extrusion. At the same time, since the friction block 501 is designed as an arc-shaped structure, the side away from the support rod 5 is the most curved side. Therefore, the extrusion force of the friction block 501 is utilized to make it difficult for the support rod 5 to rotate after being inserted into the positioning hole 302.

[0053] When it is necessary to adjust the connection position between the connecting frame and the U-shaped support plate 3, the supporting rod 5 is pulled in the direction away from the connecting rod 4. At this time, the supporting rod 5 drives the limiting slider 502 and the friction block 501 to move synchronously. When the insertion between the supporting rod 5 and the positioning hole 302 is released, the connection position between the connecting frame and the U-shaped support plate 3 can be adjusted, that is, the supporting rod 5 is inserted into the positioning holes 302 at different positions. In this solution, the adjusting groove 301 is provided so that when the supporting rod 5 and the positioning hole 302 are released from insertion, it will also be restricted in the adjusting groove 301, making it more convenient to adjust the insertion with the positioning holes 302 at different positions.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
