Probe protection and conversion device of ultrasonic flaw detector

The invention relates to the technical field of flaw detection equipment, in particular to an ultrasonic flaw detector probe protection and conversion device. Comprising a flaw detector and a protection assembly, the flaw detector comprises a shell and a probe, the protection assembly comprises an adjusting rod, a connecting rod, a driving rod and a protection cover, when the flaw detector is not used, the probe is arranged in the shell, so that the probe is effectively prevented from being collided by the outside, and when the flaw detector is used, the driving rod drives the adjusting rod to move the connecting rod downwards; when the probe makes contact with an object to be detected, the probe is protected through the protective cover and prevented from colliding with the object to be detected and being damaged, after the probe detects the object to be detected, the driving rod reversely drives the adjusting rod, the connecting rod and the probe are retracted into the shell, and the probe is protected.
