The invention provides a satellite capture anchor fluke based on a flexible capture mechanism. Comprising a shell, a connecting rod, a baffle, a baffle fixing rod, a sliding block, an anchor tail, a fixed pulley, a finger chain and a traction rope. The shell is composed of an anchor head and an anchor body, and the finger chain is formed by rotationally connecting a plurality of knuckles. The anchor body and the anchor tail are each provided with a cavity, four limiting guide rails are arranged on the inner wall of each cavity, the sliding blocks are fixedly connected with the connecting rod, the first sliding block is arranged in the anchor body, the second sliding block is arranged in the anchor tail, the first baffle is fixed to the rear end face of the anchor body, the second baffle is fixed to the front end face of the anchor tail, and the baffles and the limiting guide rails limit the sliding blocks to only move front and back in the cavities. One end of the traction rope is fixed to a barb knuckle at the tail end of the finger chain, the other end of the traction rope is fixed to a finger chain supporting plate of the anchor tail, in the recovery process, under the action of the recovery rope, relative displacement is generated between the anchor tail and the shell, the traction rope is tensioned, and the finger chain is pulled to bend and hold a target satellite tightly; the space satellite capturing device is simple in structure, low in manufacturing cost, convenient to operate and capable of capturing space satellites.

本发明提供了一种基于柔性捕获机构的卫星抓捕锚爪。包括壳体、连接杆、挡板、挡板固定杆、滑块、锚尾、定滑轮、指链、牵引绳；壳体由锚头和锚体组成，指链由若干个指节转动连接；锚体和锚尾均设有空腔，空腔内壁上设有四个限位导轨，滑块与连接杆固连，第一滑块置于锚体中，第二滑块置于锚尾中，第一挡板固定在锚体后端面，第二挡板固定在锚尾前端面，挡板和限位导轨限制滑块只能在空腔内做前后移动，牵引绳一端固定在指链末端的倒钩指节上，另一端固定在锚尾的指链支撑板上，回收过程中，在回收绳索的作用下，锚尾与壳体产生相对位移，牵引绳拉紧，牵引指链弯曲抱紧目标卫星；本发明结构简单，造价低，操作方便，可实现对空间卫星的捕获。
