Multi-pin micro-Newton colloid thrustor

The invention discloses a multi-pin micro-Newton colloid thrustor which comprises an insulating envelope, a sleeve, through-wall joints, multi-pass, capillary pipelines, an insulating base, a metal gasket, an extracting pole, an accelerator, an insulating spacer, an insulating sleeve ring, an insulating bolt, emitting poles and leads; wherein, the capillary pipelines are connected with the multi-pass in the sleeve, the multi-pass is connected with a plurality of capillary pipelines used for outputting, and the capillary pipelines are respectively connected with the through-wall joints on the insulating base; the other end of each through-wall joint is connected with one emitting pole; the two ends of the leads are fixed on the insulating base and the insulating envelope; the bottom end of the sleeve is connected with the insulating envelope, and the top end thereof is connected with the insulating base by the insulating bolt; the insulating bolt is sequentially provided with nuts, the extracting pole, the insulating sleeve ring, the accelerator and the insulating spacer. The invention can conveniently form different types of thrustors by changing the internal diameter of the emitting pole, adjusting the distance between the emitting poles and the extracting pole, increasing or decreasing the number of the through-wall joints and the emitting poles as well as replacing the multi-pass, thus realizing different regulating ways of the performance of the thrustor.
