[0020] See also Figure 1-Figure 5 , the present invention provides a technical solution: A portable, liftable, self-powered light source plant photography device includes a frame mechanism 1, wherein a lifting light source mechanism 2 is provided inside the frame mechanism 1 for adjusting the height of the photography light. The lifting light source mechanism 2 includes: The quick disassembly unit 21 is provided inside the frame mechanism 1 and is used to facilitate the disassembly and assembly of the mechanism; The lifting unit 22 is arranged below the quick disassembly and assembly unit 21, and includes a shell 227. A group of shaft columns 221 are symmetrically and rotatably installed inside the shell 227. A primary linkage arm 222 is fixedly installed on the surface of the shaft column 221, and a secondary linkage arm 223 is rotatably installed at one end of the primary linkage arm 222. The bottom of the secondary linkage arm 223 is rotatably connected to the installation platform 225 through a hinge seat 224, and a light ring 226 is fixedly installed at the bottom of the installation platform 225. The shaft column 221 is driven by the driving component 3 to realize the arc rotation of the secondary linkage arm 223, and the secondary linkage arm 223 and the installation platform 225 are linked to realize the height adjustment of the light ring 226.

[0021] The height of the light ring 226 can be finely adjusted through the coordinated action of the primary linkage arm 222 and secondary linkage arm 223 of the lifting unit 22, along with the worm gear drive assembly 3. The adjustment knob shaft 35, via the small bevel gear 36 and large bevel gear 34, drives the worm 33 and worm gear 31, which in turn drives the shaft column 221 to control the arc-shaped movement of the linkage arm, achieving stepless adjustment of the light source height. This design solves the problem of a fixed light source being unable to adapt to the height of different plants, ensuring uniform illumination at the target location and significantly improving image quality.

[0022] In this embodiment, the driving mechanism 3 includes a first gear 31 fixedly mounted on the surface of the active arm 221, a transmission shaft 32 is rotatably mounted inside the fixed shell 227, a second gear 33 is fixedly mounted on the surface of the transmission shaft 32, and the second gear 33 is meshed with the first gear 31.

[0023] In this embodiment, an adjustment knob shaft 35 is installed through the front side of the shell 227, and a small bevel gear 36 is fixedly installed on one end of the adjustment knob shaft 35.

The reflector slides over the frame to create a closed shooting space. Combined with the self-supplied light source's ability to be raised and lowered, it provides uniform fill light at varying heights.
