The invention discloses a fixed reducing external drive sleeve unfolding device which is used for unfolding sleeve assemblies which are sequentially connected in a sleeved mode and unfolded in the axis direction, and the device comprises second pre-tightening driving assemblies evenly distributed in the circumferential direction of the sleeve assemblies, and second pre-tightening driving assemblies evenly distributed in the circumferential direction of the second pre-tightening driving assemblies. The sleeve assembly can be sleeved with the second power assembly; the fixed end of the second pre-tightening driving assembly is fixedly connected with the outermost sleeve of the sleeve assembly; the second power assembly is fixedly connected with the outermost sleeve of the sleeve assembly, and the output end of the second power assembly is in transmission connection with the input end of the second pre-tightening driving assembly; the output end of the second pre-tightening driving assembly is provided with a driving mechanism, the driving mechanism abuts against the outer wall of a center-stage sleeve of the sleeve assembly, and the device has the beneficial effects of being compact in structure, high in reliability, large in unfolding driving force, high in unfolding and folding ratio and easy to control.

    本发明公开了一种固定式变径外驱套筒展开装置,用于展开依次套接并沿轴线方向展开的套筒组件,该装置包括:沿所述套筒组件周向均匀分布的第二预紧驱动组件;能够套设于套筒组件外部的第二动力组件;所述第二预紧驱动组件的固定端与所述套筒组件最外级套筒固连;所述第二动力组件与所述套筒组件最外级套筒固连,其输出端与所述第二预紧驱动组件的输入端传动连接;所述第二预紧驱动组件的输出端配置驱动机构,所述驱动机构与套筒组件的中心级套筒的外壁抵接,本发明具有结构紧凑、可靠高,展开驱动力大,展折比高,易于控制的有益效果。
