倾斜杆设计避免了执行机构干涉反应釜的情况，球体采用无机料设计，球面弧形与连接罐底弧形法兰保持一致，形成无死角连接，避免物质残留。

The inclined rod design avoids the interference of the actuator with the reaction kettle. The sphere adopts an inorganic material design, and the spherical arc is consistent with the curved flange at the bottom of the connecting tank, forming a dead angle connection and avoiding material residue.
