Nondestructive testing device suitable for different detection pieces

The utility model discloses a non-destructive testing device suitable for different testing pieces, which comprises a non-destructive testing instrument probe, the non-destructive testing instrument probe is in threaded connection with a support fixing ring, and two sides of the support fixing ring are respectively provided with an opening. Firstly, the stable clamping block rotates with the fixing rod as the center and then pokes the metal poke elastic piece, so that the metal poke elastic piece can continuously poke the stable clamping block, and then the stable clamping block drives the polyurethane clamping ring to be clamped on a pipeline. And finally, the pipelines with different pipe diameters clamped by the stable clamping block and the polyurethane clamping ring are detected by a nondestructive detector probe, so that the device has the advantage of being stably arranged on various pipelines for detection. The non-destructive testing device replaces the mode that an existing non-destructive testing d
