[0040] At least three support legs 14 are installed on the lower surface of the base plate 1 and are spaced apart from each other.

[0041] The two grooves 7 are both arc-shaped grooves.

[0042] One end of the ultrasonic knife rod is rigidly connected to the transducer, and the transducer is placed in the clamping area surrounded by the positioning block and the clamping block to clamp the transducer with the ultrasonic knife rod installed, and the other end of the ultrasonic knife rod is located above the supporting cushion layer, which can not only realize the clamping and positioning of one end of the ultrasonic knife rod installed on the transducer, but also stably support the other end of the ultrasonic knife rod;

[0045] During this process, the laser beam emitted by the laser generator irradiates the end face of the tool rod head, and the reflected light generated is received by the receiving screen to form a light spot. When the tool rod is stationary, the memory value is reset to zero, and the position of the light spot is set to zero. When the tool rod vibrates, the position of the light spot reflected from the end face vibrates accordingly. At this time, the displacement sensor converts the position of the light spot into an electrical signal and outputs it to the memory. The memory displays the distance that the light spot deviates from the zero position and transmits it to the computer, and the vibration waveform is exported through the supporting software.

[0046] When the above-mentioned ultrasonic knife rod testing platform is used, it realizes the clamping and positioning of one end of the ultrasonic knife rod installed on the transducer, and at the same time, stably supports the other end of the ultrasonic knife rod, thereby ensuring the stability of the ultrasonic knife rod during the test to improve the test accuracy, and can reduce the friction force of the ultrasonic knife rod during vibration through the rollable support pad layer to avoid damage.
