The invention discloses a spray pipe type moonlet flexible capturing tool, belongs to the technical field of satellite capturing, and aims to solve the problems of an existing satellite capturing device. Comprising an umbrella rod and capturing arms, a ball screw assembly comprises a screw rod and a screw sleeve, the rear end of the screw rod is connected with the output end of a capturing motor, the screw sleeve is in sliding fit with a front end shell, a ball head structure is arranged at the front end of the umbrella rod, the rear end of the umbrella rod stretches into the front end shell and is connected with the screw sleeve, and the multiple capturing arms are arranged on the periphery of the umbrella rod; the front end of the front rod is hinged to the ball head structure, the rear end of the rear rod is hinged to the front-end shell, the front rod is hinged to the rear rod, and when the capturing motor drives the screw sleeve to slide forwards, the umbrella rod stretches forwards to drive the middle portions of the capturing arms to be folded towards the umbrella rod, and when the capturing motor drives the screw sleeve to slide backwards, the umbrella rod retracts backwards to drive the middle portions of the capturing arms to be unfolded away from the umbrella rod. The umbrella rod and the capturing arm extend into the throat of the spray pipe, and the capturing arm is unfolded to realize lossless flexible capturing of the satellite.

    一种喷管式小卫星柔顺捕获工具,属于卫星捕获技术领域,本发明为了解决现有卫星捕获装置存在的问题。包括伞杆和捕获臂,滚珠丝杠组件包括螺杆和丝套,螺杆的后端与捕获电机的输出端相连,丝套与前端外壳滑动配合,伞杆的前端设有球头结构,伞杆的后端探入前端外壳内,并与丝套相连,伞杆的外周设有若干捕获臂,捕获臂包括前杆和后杆,前杆的前端与球头结构铰接,后杆的后端与前端外壳铰接,前杆与后杆铰接,捕获电机驱动丝套向前滑动时,伞杆前伸带动若干捕获臂的中部朝向伞杆收拢,捕获电机驱动丝套向后滑动时,伞杆后缩带动若干捕获臂的中部背离伞杆撑开,伞杆和捕获臂伸入喷管的喉道处,捕获臂撑开即可实现对卫星的无损柔性捕获。
