Adjustable fixing device for coil eddy current detection

The utility model belongs to the technical field of eddy current detection, and particularly relates to a coil eddy current detection adjustable fixing device which comprises a fixing seat, a detection coil is slidably connected to the inner wall of the fixing seat, two second rotating shafts are symmetrically and fixedly arranged on the inner wall of the fixing seat, and limiting plates are rotatably connected to the circumferential outer walls of the two second rotating shafts. And movable grooves are formed in the outer walls of the two limiting plates correspondingly, a second bidirectional threaded rod is rotationally connected to the inner wall of the fixing base, and the two ends of the second bidirectional threaded rod penetrate through the movable grooves correspondingly. By rotating a second two-way threaded rod, the two ends of two push rods can synchronously and reversely slide along the inner wall of a limiting hole, the two push rods can push limiting plates to rotate along a second rotating sha
