The invention provides a thruster system with an adjustable thrust vector. The thruster system comprises a first vector adjusting mechanical arm, a second vector adjusting mechanical arm, a satellite body, an electric thruster and a rotary joint. The first vector adjusting mechanical arm and the second vector adjusting mechanical arm are arranged on a satellite body. The electric thrusters are arranged on the first vector adjusting mechanical arm and the second vector adjusting mechanical arm; the first vector adjusting mechanical arm and the second vector adjusting mechanical arm reach the target position of the thrust vector through the rotating joint. The invention further provides a working method suitable for the thruster system with the adjustable thrust vector. According to the method, the plume field angle requirement of the electric thruster is met, meanwhile, the number of thrusters is small, and the on-orbit thrust vector can be adjusted in real time.
