At this time, the magnetic ring and the iron ring are magnetically attracted to each other, and the overall connection is relatively stable. At the same time, the connecting ring and the balloon body are fixedly connected, so that the balloon body can seal the overall mounting groove. When the connecting ring is installed into the interior of the sealing groove, the air pump tube and the adapter ring are connected. The mounting holes are adapted to each other, and then the air in the connecting ring and the balloon body can be automatically discharged through the vacuum pump tube, so that the balloon body will fit with the outer surface of the transducer mounting tube, and the overall sealing effect on the transducer body is good, so the overall installation operation is relatively simple and the sealing effect is better, and then the transducer mounting tube is installed as a whole into the inside of the mounting groove, so that the installation between the catheter body and the transducer mounting tube is completed, and then the right side of the mounting ring will conflict with the left side of the mounting ring, and then the plug will be inserted into the inside of the jack, so that the overall installation between the transducer mounting tube and the catheter body is relatively stable, reflecting the functionality of the design.

When the positioning block and the connecting block are connected, the blocking plate is pushed downward inside the connecting plate, so that the right side surface of the blocking plate will fit the left side surface of the positioning block. Therefore, the position of the positioning block and the connecting block after installation can be stabilized, and the overall stabilizing effect is good. When the operation is completed, the stabilizing block is held and the blocking plate is pulled upward as a whole, and then the blocking plate releases the positioning block and the connecting block. The limiting effect of the connecting block, when the positioning block and the connecting block release the limiting effect, the elastic design of the spring body can automatically push the positioning block to the left, so that when the positioning block moves to the left, the mounting ring and the catheter body as a whole will also be pushed to the left, so that the catheter body and the transducer mounting tube can be automatically separated, avoiding the previous manual separation of the two. At the same time, the mounting ring can be unscrewed from the outer surface of the catheter body for recycling, and then the mounting ring is connected to the guide ring through the telescopic tube.
