An adjusting buckle 52 is also arranged at the end of the inner shaft 53, and the positioning buckle 55 is movably arranged in an arc-shaped adjusting port 57, and the arc-shaped adjusting port 57 is arranged on the outer surface of the piston rod 5. One end of the positioning buckle 55 can be clamped in the positioning groove 56, and the positioning groove 56 is provided with the inner surface of the annular buckle 54, and the annular buckle 54 is arranged on one side of the medicine storage tube 2, which further improves the stability of the piston rod 5 when carrying, and avoids the situation that the connecting buckle 7 is broken due to extrusion. A through groove 58 is also arranged on one side of the annular buckle 54, and the positioning buckle 55 can be guided out. The adjusting buckle 52 is arranged in the countersunk groove 51, and the countersunk groove 51 is arranged on one side of the push plate 4. A limit buckle 59 arranged at a 90° angle is also arranged in the countersunk groove 51, which can position the rotation position of the adjusting buckle 52.

[0042] In one embodiment, the sealing film 12 is preferably made of Fig.12 In the structure shown, the sealing film of this structure is easily torn apart along the tearing line under the action of external force, and the film will not remain in the hemostatic material, thereby improving the injection efficiency and the safety of the push syringe.

[0043] In this embodiment, the adjusting buckle 52 is arranged in parallel with the positioning buckle 55. When carrying, please refer to Figure 10. The adjusting buckle 52 is rotated clockwise, and the adjusting buckle 52 drives the inner shaft 53 to rotate, and the inner shaft 53 drives the positioning buckle 55 to rotate, and the positioning buckle 55 is snapped into the positioning groove 56.
