蜗轮手摇磨豆机购买证据主图

以「蜗轮手摇磨豆机」为题生成独立视觉作品，实际用途是展示「蜗轮手摇磨豆机」在写实使用中的购买证据。
把「蜗轮手摇磨豆机」放进它真正会被使用的环境，主角约占成片 55%，手部只完成一次与低速轴承剖面、二十圈出粉量和粗细调节刻度共同证明手感直接相关的行为
低速轴承剖面、二十圈出粉量和粗细调节刻度共同证明手感
让「蜗轮手摇磨豆机」的操作前状态、不锈钢锥刀、铝合金机身与木质摇柄的受力或连接位置、操作后的可判断变化同时出现；局部放大只解释低速轴承剖面、二十圈出粉量和粗细调节刻度共同证明手感涉及的构造，无法从本次动作观察到的性能不要视觉化。
构图采用双栏对照加底部结论带。
标题锁定为「蜗轮手摇磨豆机」，只补充完成理解所需的中文标注。
限定夜蓝、荧光青、酸橙绿与银灰，材料按不锈钢锥刀、铝合金机身与木质摇柄精确表现，切口、接缝和固定方式均可辨认。
为「蜗轮手摇磨豆机」保留镜头透视克制、边缘不变形和均匀漫射顶光；不额外增加物料，重点是准确表现不锈钢锥刀、铝合金机身与木质摇柄的接缝、厚度、开合与接触阴影。版面以移动端缩略图仍可辨的字号层级落在低饱和冷灰底面，成片呈可信的商业产品摄影质感。补充控制：层次直观的浅灰投影，印刷套色边缘精确；用留白对比密集细节，主视觉清晰，注释区保留同等可读，对比最高的位置就是阅读入口。
不得出现夸大功效、错误握持、漂浮零件、无关赠品、虚构认证与摆拍式手势；成片物理、文字和人物身份在全部区域保持一致。
成片为单张 2:3，不附过程页或变体。

Generate a complete visual work titled “Wolun Hand-Crank Coffee Mill,” whose practical purpose is showing purchase-relevant evidence for “Wolun Hand-Crank Coffee Mill” in real use. Place Wolun Hand-Crank Coffee Mill in the environment where it would genuinely be used. Let the product occupy roughly fifty-five percent of the finished picture and simultaneously one hand performs a single task tied to its defining function for Wolun Hand-Crank Coffee Mill. Show the purchase-defining function of Wolun Hand-Crank Coffee Mill via an observable operation involving stainless conical burrs, aluminum body, and wooden crank, keeping the operated part and the resolved form in one line of sight. Maintain the pre-use state of Wolun Hand-Crank Coffee Mill, the contact or load point in stainless conical burrs, aluminum body, and wooden crank, and the observable after-state together. Restrict its cutaway or macro inset to construction involved in the demonstrated operation; omit any performance that this precise action cannot reveal for Wolun Hand-Crank Coffee Mill. Frame Wolun Hand-Crank Coffee Mill as two-column comparison with a conclusion band, seen by a realistic 35–55mm commercial view placed near the height of operation. Lock the title to “蜗轮手摇磨豆机” and add only the Chinese labels required for comprehension. Limit the image to night blue, luminous cyan, lime green, and silver gray and describe stainless conical burrs, aluminum body, and wooden crank precisely, including cuts, seams, and fastening methods. For Wolun Hand-Crank Coffee Mill, retain restrained perspective without edge distortion and even diffused overhead light. Add no unrelated surface treatment: render the seams, thickness, opening behavior, and contact shadows of stainless conical burrs, aluminum body, and wooden crank accurately. Additional control: clearly layered pale-gray shadows; printed color edges register precisely. Use negative space opposing dense detail, ensure hero and annotation zones remain equally legible, and let the highest-contrast point become the reading entry for Wolun Hand-Crank Coffee Mill. Do not permit exaggerated claims, incorrect handling, floating components, irrelevant gifts, fabricated certification, or posed gestures; physics, text, and character identity stay consistent across the entire visual field. Return one 2:3 final image without variants or a process sheet. Final art direction: evidence-led commercial product photography with honest materials and restrained studio light. Use only this controlled palette: #F2EFE7, #22262A, #7B9B8A, #C86B42; preserve believable local material color inside that system. Keep one unmistakable primary subject and one readable action. The eye must enter at the action contact point, then read the consequence and finally the setting. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Human hands must be complete and anatomically plausible. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No visible text, letters, numerals, logos, brand marks, signatures, interface elements, labels, captions, borders, or watermarks anywhere in the image. Avoid plastic gloss, waxy skin, generic luxury-ad lighting, excessive bloom, meaningless lens flare, floating objects, duplicated limbs, clutter, random decorative icons, and synthetic AI collage artifacts. Return exactly one finished image composed for 2:3; no variants, process sheet, split panels, mockup frame, or contact sheet.
