The invention discloses a probe system multi-filed loading device, which comprises a multi-field loading box, a horizontal mobile platform, a cantilever rod, a fixed support with a slide rail, a transmission shaft, a servo motor, a probe and a force sensor, wherein the multi-field loading box is fixed on the horizontal mobile platform, a sample is fixed on a box bottom, a perform hole is sealed through a sealing rubber ring, the top portion of the probe is contacted with the sample, the bottom portion of the probe is connected with the force sensor, the force sensor is arranged in the front end of the cantilever rod, and is not contacted with the sealing rubber ring, the servo motor drives the transmission shaft to rotatably control the probe to vertically move, and achieves to load a force filed and a deformation field, the outer portion of the servo motor can be connected with a vacuum pump and a humidity controller, and a box body is embedded into a ring-shaped heating bar and an iron bar which twines a copper wire, is used to load a heating field and a magnetic filed, and loads an optical field through a panel. The probe system multi-filed loading device can supply load of vacuum degree, humidity, the force field, the deformation filed, an electric field, the heating field, the magnetic filed and the optical field, and is strong in anti-jamming ability and reliable and accurate in test result.
