The other end of 56 is fixedly connected to the surface of the inner ring 57, and the inner wall of the inner ring 57 is fixedly connected with a spiral protrusion strip 58. When the top cover 2 is pressed, the top cover 2 drives the connecting transmission rod 51 to move downward, and the connecting transmission rod 51 drives the fixed block 52 to move downward, and the fixed block 52 drives the rotating block 53 to move downward, and the rotating block 53 contacts the spiral protrusion strip 58. The inclined surface of the spiral protrusion strip 58 drives the outer ring 55, the impeller 56, and the inner ring 57 to rotate. The rotation of the impeller 56 drives the liquid medicine to mix. The top cover 2 is released, and the top cover 2 drives the connecting transmission rod 51 and the fixed block 52 to move upward. The fixed block 52 drives the rotating block 53 to move upward through the torsion spring 54. The rotating block 53 and the fixed block 52 squeeze the torsion spring 54, so that the rotating block 53 rotates downward, so that the rotating block 53 cannot conflict with the movement of the spiral protrusion strip 58. The top cover 2 is pressed back and forth, so that the impeller 56 rotates continuously to mix the liquid medicine, which has the effect of homogenizing the liquid medicine. The number of the spiral protrusion strips 58 is six, and the six spiral protrusion strips 58 are arranged in a circle, so that the spiral protrusion strips 58 can be conflicted downward by the rotating block 53 at multiple positions. The top of the fixed block 52 is fixedly connected with a square block, and the bottom of the top square block of the fixed block 52 conflicts with the top of the rotating block 53, so that the rotating block 53 will not rotate upward relative to the fixed block 52. The connecting transmission rod 51 is Z-shaped, which plays the role of connecting transmission and avoiding the spiral protrusion strip 58. The top of the bottom cover 1 is provided with a through hole, which plays the role of passing the liquid medicine.

The spring 41 drives the top cover 2 to move upward to the position as shown in FIG. Figure 3 At this time, since the infusion needle is located in the telescopic tube 42, and the volume of the telescopic tube 42 is smaller than the bottom cover 1, the infusion needle is located in the telescopic tube 42 to reduce the waste of the remaining liquid medicine.
[0025] When it is necessary to add additional liquid medicine to the infusion container, the liquid medicine is injected by piercing the rubber barrier 43 with a syringe, and then the top cover 2 is pressed, the top cover 2 drives the connecting transmission rod 51 to move downward, the connecting transmission rod 51 drives the fixed block 52 to move downward, the fixed block 52 drives the rotating block 53 to move downward, the rotating block 53 contacts the spiral protrusion strip 58, the inclined surface of the spiral protrusion strip 58 drives the outer ring 55, the impeller 56, and the inner ring 57 to rotate, the impeller 56 rotates to mix the liquid medicine, and when the top cover 2 is released ... The spring 41 drives the top cover 2 to move upward, and the top cover 2 drives the connecting transmission rod 51 and the fixed block 52 to move upward. The fixed block 52 drives the rotating block 53 to move upward through the torsion spring 54. The rotating block 53 and the fixed block 52 squeeze the torsion spring 54 to make the rotating block 53 rotate downward, so that the rotating block 53 cannot resist the movement of the spiral protrusion strip 58. The top cover 2 is pressed back and forth in this way, so that the impeller 56 keeps rotating to mix the liquid medicine, thereby achieving the effect of homogenizing the liquid medicine.
