Calibration device for human body electrostatic detector

The utility model relates to the technical field of electrostatic detectors, in particular to a calibration device for a human body electrostatic detector, which comprises a base, a planar electrode is fixedly connected to the top of the base, a protective plate is fixedly connected to the top of the base, the protective plate is positioned on the peripheral side of the planar electrode, and a sliding rail is fixedly connected to the top of the base. A sliding rail is arranged on the mounting base, a sliding block is slidably connected to the sliding rail in a sleeved mode, a threaded groove is formed in one side of the sliding block, a threaded rod is connected into the threaded groove in a threaded mode, and a fixing block is rotationally connected to the threaded rod in a sleeved mode. And a threaded rod rotates to drive a sliding block to move on a sliding rail, so that an arc-shaped fixing rod extrudes T-shaped extrusion blocks to move, the two T-shaped extrusion blocks move mutually to center the positi
