[0025] In this embodiment, a threaded rod 7 is vertically disposed on one side of the storage barrel 1, and the lower end of the threaded rod 7 is rotatably connected to the upper end of one side of the storage barrel 1, such as Figure 1 and Figure 2 As shown, a transmission block 8 is arranged outside the threaded rod 7, and the inside of the transmission block 8 cooperates with the external thread of the threaded rod 7, a support frame 6 is arranged at the upper end of the threaded rod 7, and the lower end of the support frame 6 is rotatably connected with the upper end of the threaded rod 7, and the threaded rod 7 can be supported vertically by the support frame 6 and the storage barrel 1, and a transmission rod 9 is arranged at the upper end of the transmission block 8, and the transmission rod 9 passes through the support frame 6 and the storage barrel 1 in sequence and is welded to the upper end of the extrusion sheet 10, and the position of the extrusion sheet 10 inside the storage barrel 1 can be adjusted by the rotation of the threaded rod 7 and the restriction of the support frame 6 on the transmission rod 9;

[0026] In this embodiment, if Figure 2 As shown, the transmission rod 9 is U-shaped, and the transmission rod 9 can be used for transmission and can also be suspended through the position of the transmission rod 9, so that the device is easy to carry and use;

[0027] In this embodiment, a temporary retention frame 2 is provided at the front end of the storage barrel 1. The liquid inside the storage barrel 1 flows into the temporary retention frame 2 after passing through the squeezing sheet 10. The liquid flowing into the temporary retention frame 2 will be extracted and the drug application requirement will be met. Figure 3 and Figure 5 As shown, a converging slope 12 is provided at the upper end of the interior of the temporary retention frame 2, and a reserved groove 13 is provided at the lowest end of the inclined position of the converging slope 12. The temporary retention frame 2 and the storage barrel 1 are sealed and connected via a second transmission hose 19, and the sealing position of the second transmission hose 19 and the temporary retention frame 2 is located at the upper end of the converging slope 12. The liquid can flow into the temporary retention frame 2 through the extrusion of the extrusion sheet 10 and the transmission of the second transmission hose 19.
