Without piezoelectric vibrators, ultrasonic diagnostic equipment will not work properly. Therefore, understanding its working principle and characteristics is essential for the use and maintenance of ultrasonic diagnostic equipment.

One end of the clamping bolt is connected to the clamping device, and the other end of the clamping bolt is connected to the rotating shaft. The clamping device includes a slider and a third bolt. The slider is slidably matched with the slide groove. The upper surface of the slider is arrayed with a plurality of third threaded through holes. The plurality of third bolts are respectively rotatably matched with the plurality of third threaded through holes.
