Further technical scheme is that the bottom of the through hole inwardly rolls tiltedly.
Further technical scheme is also resided in, and top surface and the left surface and right side surface chamfer of the probe body are formed respectively
Two inclined-planes, described two inclined-planes are vertical with the axis of the through hole of probe body left and right ends respectively.
Further technical scheme also resides in, and is connected through a screw thread between the boss and through hole.
Further technical scheme also resides in, and the middle part of the through hole is provided with the space formed by reaming, the space and
The top of boss and cavity for depositing coupling liquid is formed with the contact head of the ultrasonic transducer of boss upper contact.
Further technical scheme also resides in, and the surface of the probe body is provided with the coupling liquid added holes that cavity communicates.
Further technical scheme is also resided in, and preventing water leakage adhesive tape is provided between the boss and through hole.
Further technical scheme also resides in, and the middle part of the probe body top surface is embedded with magnet.
Further technical scheme also resides in, and the middle and lower part before the probe body is provided with rectangle void region.
Further technical scheme also resides in, and the boss bottom surface is away from probe body bottom surface 1.5mm.
It is using beneficial effect caused by above-mentioned technical proposal：It is connected through a screw thread, realizes between boss and through hole
Boss and probe body it is separable；The middle part of through hole is provided with the top in the space formed by reaming, the space and boss
And the cavity for depositing coupling liquid is formed with the contact head of the ultrasonic transducer of boss upper contact, addition coupling liquid can
To exclude the air between boss top and ultrasonic transducer, ultrasonic wave effectively penetrates boss；Set between boss and through hole
There is preventing water leakage adhesive tape, the coupling liquid seepage in cavity can be prevented；The coupling liquid added holes that the surface cavities of probe body communicate,
Convenient addition coupling liquid；Middle and lower part before probe body is provided with rectangle void region, tests prove that probe material can be reduced
Material expands with heat and contract with cold, and also reduces interference of the probe body to ultrasonic wave.
