3. When cardboard right side board removed the right side of puncture needle tubing, the cardboard wholly moves down, no longer with the clamp plate with dial the board contact, it is rotatory just no longer to stir the pivot, be in stable state after being full of gas in the gasbag, the pivot resets under the effect of torsional spring, the magnetic path is with long magnetic stripe top back simultaneously, the inside of gasbag is stretched out again to the impeller, all the other baffles also stretch out again, through this kind of setting, guaranteed to move needle tubing position department at the cardboard, it is stable until gasbag internal gas pressure, whole journey has the baffle to fix the position of cardboard, through setting up the both sides of cardboard fixing card at puncture needle tubing, thereby the phenomenon that the needle tubing took place the dislocation in the blood vessel has been avoided.

4. Through setting up a plurality of baffles, guaranteed that even the needle tubing does not align with the mark line, the cardboard also can be according to the automatic card in the needle tubing outside of the actual position of needle tubing, and the location is accurate, has played good fixed effect.

5. When not needing the oppression, deflating the gasbag, the air current drives the blade rotation once more through the outside exhaust in-process of trachea for the magnetic path separates with the magnetic conduction board, and the baffle is whole to be shrunk into, and the air current can drive the cardboard this moment and get back to initial position, has accomplished automatic re-setting work, and easy operation is convenient.
