The invention discloses a jacking mechanism which comprises a driving structure and a floating disc, the driving structure is connected with a transmission structure, the transmission structure is connected with a lifting structure, the lifting structure is connected with the floating disc, a guide structure is arranged on the floating disc, the driving structure drives the transmission structure to rotate, and the lifting structure jacks up the floating disc. And the floating disc moves up and down along the guide structure. According to the jacking mechanism provided by the invention, the floating disc and the contact ball are in spherical contact, so that the upper floating disc slides in the jacking and descending processes, and the blocking phenomenon is prevented.
本发明公开了一种顶升机构,包括驱动结构和浮动盘,驱动结构连接有传动结构,传动结构连接有举升结构,举升结构和浮动盘相连,浮动盘上设置有导向结构,驱动结构驱动传动结构转动,举升结构顶起浮动盘,以使浮动盘沿导向结构上下移动。本发明提供的顶升机构通过设置浮动盘和接触球为球面接触,实现上浮动盘在顶升下降中滑动,防止憋死现象。
