Zusammenfassung:The invention provides an elastic mechanism of a switching device. The elastic mechanism comprises a slide block (12), a first spring (14), a second spring (16) and a base (18), wherein one end of the first spring can abut against the slide block; the second spring can sleeve the outer side of the first spring; one end of the second spring can abut against the slide block. The base comprises a bearing surface (182) arranged towards the slide block, a first limiting part (184) convexly arranged on the bearing surface, and a second limiting part (186) convexly arranged on the bearing surface; the first spring can sleeve the first limiting part and abuts against the bearing surface; the second spring can be embedded into the second limiting part and abuts against the bearing surface.
