When the puncture sleeve 6 needs to be fixed so that the puncture sleeve 6 is not easy to shake when the puncture sleeve 6 is connected to the pipeline without holding the puncture sleeve 6, the bidirectional lead screw 4014 is rotated at this time. The surface of the bidirectional lead screw 4014 has two threads in opposite directions, so the bidirectional lead screw 4014 drives the two clamping blocks 4015 to approach each other and fit the surface of the puncture sleeve 6 at the same time, so as to fix the puncture sleeve 6.

At the same time, the puncture position is adjusted through the telescopic effect of the damping rod 3014. At this time, the puncture position of the puncture sleeve 6 can be adjusted without constantly adjusting the installation position of the rubber sleeve ring 1, which is more convenient. When the adjustment is completed, the puncture position needs to be fixed to facilitate the stable puncture of the puncture sleeve 6. At this time, the pushing seat 3033 is pressed down. At this time, the pushing seat 3033 pushes the pushing inclined block 3031 to be pressed down, and the pushing plate 3023 is pushed to move by pushing the inclined surface of the inclined block 3031. At this time, the pushing plate 3023 pushes the spring 3021 to move, and the spring 3021 pushes the sticker The seat 3024 fits the surface of the rotating ball 3013 to fix the rotation of the rotating ball 3013. At the same time, the damping extension and retraction of the damping rod 3014 will not shake at will, so that the sliding limit ring 5 and the puncture sleeve 6 will not rotate at will during puncture, which is more stable. At this time, the puncture sleeve 6 is pressed down for puncture. When the puncture depth is reached, the two-way screw 4014 is rotated, so that the two-way screw 4014 drives the two clamping blocks 4015 to approach and fit the surface of the puncture sleeve 6 at the same time to fix the puncture sleeve 6. At this time, air can be output and input into the body to form a cavity for convenient surgical operations. During the puncture process, the puncture position of the puncture sleeve 6 is adjusted to a certain extent, which is convenient for accurate puncture of the appropriate position. At the same time, after the adjustment is completed, the puncture sleeve 6 can be conveniently fixed, so that the puncture needle 7 is more stable, not easy to shake, and the inflation position is more accurate.
