[0032] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0033] In summary, with the aid of the above technical solution of the present invention, when installing the camera device 18, first, the blocking of the opening of the placement slot 44 is released by the blocking component (that is, the toggle lever 15 is toggled downward, and the toggle lever 15 drives the rotating plate 2 8 to rotate on the support shaft 1 5, and the other end of the rotating plate 2 8 drives the rotating plate 1 7 to rotate synchronously on the support shaft 2 6. While rotating, the blocking plate 14 on the side of the rotating plate 2 8 gradually moves away from the opening of the placement slot 44 toward the accommodating shell 3, and the movable shaft 13 at the end of the rotating plate 2 8 slides in the movable hole 10 on the rotating plate 1 7, and rotates while sliding). The end of the second plate 8 pushes the movable plate 12 to slide on the rotating plate 1 7, and the movable plate 12 compresses the buffer spring 11 at the same time. When the rotating plate 2 8 rotates to be squeezed together with the side limit rod 16, the blocking plate 14 is stored in the accommodating shell 3, and the buffer spring 11 stretches to provide power for the reset of the movable plate 12, thereby transmitting the pressure to the end of the rotating plate 2 8 to prevent the rotating plate 2 8 from rotating). Then, the stabilizing block 21 and the connecting block 22 on the top of the camera device 18 are respectively inserted into the stabilizing groove 17 and the placement groove 44. When the connecting block 22 is completely inserted into the placement groove 44, The staff manually pulls the toggle lever 28, and the toggle lever 28 moves from one end of the opening 34 to the other end. During this process, the toggle lever 28 drives the rotating shaft 23 to rotate through the connecting seat 27. The top of the rotating shaft 23 drives the gear 24 to rotate. The gear 24 drives the rack plate 25 to move and squeeze the buffer spring 26. The bottom end of the rotating shaft 23 drives the rotating disk 29 to rotate. The three arc-shaped convex edges 30 of the rotating disk 29 squeeze the touch block 33 during the rotation process. The touch block 33 drives the extrusion member 32 to rotate with the fixed shaft 31 as the fulcrum. The outer surface of the other end of the extrusion member 32 pulls the tension spring. The end of the extrusion piece 32 will be stuck in the extrusion groove on the connecting block 22, thereby confining the connecting block 22 in the placement groove 44, and then fixing the camera device 18 and the mounting base 1 together. At this time, when the toggle lever 15 is pushed downward, the blocking plate 14 gradually rotates to the opening of the placement groove 44 to block the connecting block 22; when disassembling the camera device 18, first rotate the toggle lever 28 to release the restriction of the extrusion piece 32 on the connecting block 22. At this time, it is only necessary to open the blocking assembly on the opening of the placement groove 44 to remove the camera device 18 and the connecting block 22 from the connecting piece 2.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
