The invention discloses an optical pump atomic magnetic sensor test fixture, and relates to a sensor test auxiliary device. The test fixture aims to solve the problems that an existing test fixture is tedious in test operation and long in test time, and steering adjustment is difficult to meet test requirements. The sensor adjusting seat comprises a cylinder body, a steering screw and a pair of positioning bolts; a sensor insertion hole is formed in the cylinder body, and an acute included angle is formed between the center axis of the sensor insertion hole and the vertical axis of the cylinder body; the pair of positioning bolts are symmetrically arranged on the two side walls of the cylinder body, and one ends of the pair of positioning bolts are spirally matched with the cylinder body; the steering screw is spirally matched with the cylinder body, and the axis of the steering screw is perpendicular to the connecting line of the axes of the pair of positioning bolts; by adjusting the ...
