银色机械装置3D线框模型

纯白背景，单个物体居中，一个银灰色的3D机械装置模型，表面覆盖着黑色细线框网格。底部为长方形基座，侧面有深凹槽和圆孔。基座上方连接圆柱形结构，圆柱前端开口，内部悬浮一个圆球。圆柱顶部延伸出一根带弯曲端头的长杆连接至左侧。金属或硬质塑料质感，高光反射，工业风，清晰的几何拓扑结构，中景特写，画幅比例16:9。

Pure white background, single object centered, a silver-gray 3D mechanical device model covered with fine black wireframe grid lines. The base is a rectangular block with deep grooves and circular holes on the side. Above the base is a cylindrical structure with an open front revealing a sphere in the center. A long rod with a curved end extends from the top of the cylinder to the left. Metallic or hard plastic texture, specular highlights, industrial style, visible geometric topology, medium close-up, aspect ratio 16:9.
