Patent attributes
A plug-in connection multi-segment rotary shaft structure includes a driving joint assembly and a driven joint assembly. The driving joint assembly includes two opposite joint plates and a middle link plate assembly engaged therebetween. The driven joint assembly is disposed between the joint plates and includes two driven plates. Opposite inward ends of the driven plates are formed with synchronous driving sections drivingly engaged with each other. Inward ends of the opposite joint plates are connected with the outward ends of the driven plates. Outward ends of the joint plates are formed with plugs. Outward ends of the middle link plate assembly are connected with the inward ends of the driven plates. The driving joint assembly and driven joint assembly are connected and combined, whereby the joint plates can be freely rotated around multiple rotational centers.
