齿轮球 Gear Ball

由围成球状的8个齿轮和中心的基体组成；

8个齿轮相互啮合，均可自由旋转；

连接处采用榫卯结构，形成卡扣牢固连接（详细结构见上图）。

The Gear Ball consists of eight gears enveloping a central base in a spherical arrangement.

Each of the eight gears interlocks with the others, permitting independent and unrestricted rotation.

The connections utilize a traditional mortise and tenon mechanism, which results in a firm and stable coupling. (For a detailed view of the structure, please consult the image provided above.)
