A third slide groove is formed at the top of the third camera base 31, and a third slider 32 is installed within the third slide groove. The third camera 3 is fixed at the beginning of the third slider 32, and an oblong hole is formed at the end. The oblong hole design allows for adjustable fixing of the corresponding sliders. Combined with the slide groove design, the camera can move along the slide groove, achieving precise position adjustment and positioning. In other words, the design of these slide grooves and sliders enables the camera to be positioned as needed.

[0060] Example 7: Cameras arranged in an alternating pattern

[0061] The heights of the first slider 15, the third slider 32, and the second slider 22 increase sequentially, forming a height difference between the first camera 1, the second camera 2, and the third camera 3, which are arranged in an alternating manner. In other words, the three cameras are arranged in an alternating manner through the design of the sliders and the base, forming a height difference. The structure is compact, makes full use of three-dimensional space, and meets the needs of efficient shooting.
