[0002] Ultrasonic phased array detection is a technology developed on the basis of traditional ultrasonic detection. It arranges some ultrasonic wafer units to form an array. During operation, through software, the excitation time of each wafer in the phased array probe can be controlled individually, so as to control the angle, focusing position and focal spot size of the generated beam.

[0003] In the prior art, as an industrial non-destructive flaw detector, when an ultrasonic phased array flaw detector is in use, the detection probe is directly placed on the workpiece to be detected, and various defects such as cracks, porosity and air holes inside the workpiece can be detected quickly, conveniently, without damage and accurately.

[0004] However, during the process of operating the ultrasonic phased array flaw detector for detection, it is usually necessary for the operator to manually place and hold the detection probe steadily. Since the operator's hand is prone to shaking, the stability of the detection probe is poor, and then the detection probe moves, resulting in a reduction in the accuracy of the detection result.

Two guide holes are correspondingly formed on the surfaces of the two clamping plates close to the two guide rods.

[0011] Preferably, one end of each of the two clamping plates slidably passes through the adjacent limiting groove and extends out of the clamping seat. A plurality of balls are rotatably installed on both inner side walls of the two limiting grooves.

[0012] Preferably, the fixed plate is fixedly installed on one side wall of the clamping seat, and a counterweight block is fixedly connected to the side wall of the clamping seat far from the fixed plate.
