The utility model provides an ultrasonic wave leads to detection of ability of swimming immersion testing uses fixing device, the device includes the base, cylinder body, handle and probe, having a under the narrow width's cylinder body on the base through threaded connection, having a probe through threaded connection on the cylinder body, the kelly articulates in the outer wall both sides of cylinder body, and it has a probe data line and a water injection hose to alternate in the drum pole, still is provided with a water injection hole on the outer wall of cylinder body, and the play water end (W. E. ) of water injection hose is connected with the water injection hole, and the data line of popping one's head in is connected with the probe through DLC, still be provided with the exhaust hole on the outer wall of cylinder body. The utility model discloses can make things convenient for ground to carry out the ultrasonic wave to the face work piece fast and lead to the fixing device that the ability of swimming immersion testing detected, be applicable to steel sheet material quality's reinspection. In the device, the probe detects not direct contact of steel sheet surface with the quilt here to avoided because of the harm of friction to the probe. In the testing process, when the wearing and tearing of base influence detect operation, the base can be changed, other component parts such as jar body are need not to change.
