The purpose of automatic extraction and quantitative dispensing is achieved. With respect to the above technical solution, although the solution realizes quantitative dispensing, the syringe cannot be quickly removed from the equipment after the dispensing is completed, which is inconvenient for subsequent injection.

[0024] In this embodiment, a fixing frame 11 is welded on the fixing seat 1, a cavity 12 is opened inside the fixing frame 11, an extrusion plate 13 is movably installed inside the cavity 12, a syringe 15 is movably installed between the extrusion plates 13, a handle 17 is fixed on the syringe 15, a blocking plate 14 is movably installed on the fixing seat 1, the handle 17 is limited and fixed between the blocking plate 14 and the fixing frame 11, a movable column 16 is movably installed inside the syringe 15, a fixing plate is fixed at one end of the movable column 16, the fixing plate is movably contacted with one side of the limiting plate 10, and the blocking plate 14 squeezes and limits the handle 17 between the fixing frame 11 and the blocking plate 14 through the elastic force of the supporting mechanism 21, so as to avoid the influence caused by the sliding of the syringe 15 on the extrusion plate 13 when the syringe extracts the drug in the later stage.

[0025] In this embodiment, a groove 24 is provided on the inner wall of the cavity 12, a reset mechanism 25 is fixed inside the groove 24, a protrusion 26 is fixed at one end of the reset mechanism 25, the protrusion 26 is fixed to one end of the extrusion plate 13, a fixing block 8 is fixed to the top of the limit block 7, a scale line 9 is provided on the side of the fixing groove 5, the fixing block 8 cooperates with the scale line 9, a slide groove 20 is provided on the fixing seat 1, a supporting mechanism 21 is fixed inside the slide groove 20, a slider 19 is fixed at one end of the supporting mechanism 21, the slider 19 is fixed to the bottom of the blocking plate 14, the supporting mechanism 21 and the reset mechanism 25 are both spring structures, the spring provides the required power for the movement of the device, the reset mechanism 25 pushes the protrusion 26 to move to the center position through the spring, so that one end of the extrusion plate 13 contacts, and later the extrusion plate 13 is adaptively adjusted through the reset mechanism 25 according to the diameter of the syringe 15.

[0026] When the device is in use, the syringe 15 is first installed between the squeezing plates 13, and the syringe 15 is pressed downward from the top of the squeezing plate 13. The syringe 15 provides squeezing force to both sides of the squeezing plate 13, and the squeezing force causes the squeezing plate 13 to move to both sides inside the cavity 12. When the squeezing plate 13 moves, the protrusion 26 squeezes the reset mechanism 25, and the reset mechanism 25 is squeezed and deformed. The reset mechanism 25 after deformation provides support force for the protrusion 26, so that the squeezing plate 13 always squeezes and fixes the syringe 15. After the syringe 15 is installed between the squeezing plates 13, the handle 17 is placed between the fixing frame 11 and the blocking plate 14. The blocking plate 14 moves to one side of the fixing frame 11 through the elastic force of the supporting mechanism 21, and the movement squeezes and fixes the handle 17 to one side of the fixing frame 11, so as to avoid the later When the movable column 16 extracts the medicine at one end of the syringe 15, the syringe 15 is affected by shaking. When extracting the medicine, the threaded column 4 is first rotated to drive the limit block 7 to adjust inside the fixed groove 5, and the distance moved by the movable column 16 is initially limited. When the limit block 7 moves, the fixed block 8 is aligned with the scale line 9 to control the moving distance. Then the movable column 16 and the fixed disk move to one side of the limit plate 10, and the limit plate 10 moves to one side without the limit of the limit block 7. When the connecting block 18 on the limit plate 10 contacts the limit block 7, the movable column 16 stops moving and the first extraction is completed. Later, the position of the limit block 7 is adjusted in turn according to the amount and proportion of the medicine, and the limit plate 10 is limited and fixed multiple times, thereby completing the quantitative dispensing of the medicine.
