The invention relates to the technical field of space propulsion, in particular to a compact pintle injector adjusting mechanism. The compact pintle injector adjusting mechanism comprises a fixing frame, a through hole type servo motor and a transmission assembly. The end of the fixing frame is connected with the head of a pintle injector, and the through hole type servo motor and the transmission assembly are installed in the fixing frame. A stator of the through hole type servo motor is connected with the fixing frame, a rotor of the through hole type servo motor is connected with the transmission assembly, and the transmission assembly is used for converting rotational motion output by the through hole type servo motor into linear motion and is connected with a moving part of the pintle injector. And at least one part of the transmission assembly is arranged in a through hole of the through hole type servo motor. The compact pintle injector adjusting mechanism is compact in mechanical structure and can be tightly combined with the head structure of the pintle injector, the structural size of the pintle injector system is reduced, and the system reliability of a pintle type variable thrust rocket engine is improved.
