[0034] The driving member includes a first motor 7 and a second motor 8;

[0035] Specifically, both the first motor 7 and the second motor 8 are fixedly connected to the inner wall of the support sleeve 3. The output end of the first motor 7 is fixedly connected with a first lead screw 701, and the output end of the second motor 8 is fixedly connected with a second lead screw 801. The first lead screw 701 and the second lead screw 801 are sequentially inserted and connected to the back surfaces of the first fixing ring plate 6 and the second fixing ring plate 10. A first flange 7011 is sleeved on the outside of the first lead screw 701 and in front of the second fixing ring plate 10, and a second flange 8011 is sleeved on the outside of the second lead screw 801 and behind the first fixing ring plate 6.

[0036] It should be noted that the first motor 7 and the first lead screw 701, and the second motor 8 and the second lead screw 801 are all connected by couplings. The first flange 7011 is fixedly welded to the second fixing ring plate 10, and the second flange 8011 is fixedly welded to the first fixing ring plate 6. Both the first fixing ring plate 6 and the second fixing ring plate 10 are provided with cylindrical holes for the lead screws to pass through. The diameter of the cylindrical hole is larger than the cross-sectional diameter of the lead screw.

[0037] During actual use, the first motor 7 and the second motor 8 move the first fixing ring plate 6 and the second fixing ring plate 10 along the lead screws towards the medicine placing box 2 through the first flange 7011 and the second flange 8011, so that the syringe needle in the syringe support table 11 of the injection tube support pierces into the medicine bottle in the placing groove 2071 along the movable hole 201. The second motor 8 withdraws the syringe piston rod fixed to the back of the first fixing ring plate 6 and the injection tube by rotating the second lead screw 801 and the second flange 8011, thereby extracting the liquid medicine in the medicine bottle. After the extraction is completed, the first motor 7 and the second motor 8 drive the first lead screw 701 and the second lead screw 801 at the same time, so that the first fixing ring plate 6 and the second fixing ring plate 10 move away from the medicine placing box 2, causing the needle of the syringe to disengage from the medicine bottle. Then, the third motor 202 drives the rotating shaft 206 to rotate, and the rotating rotating shaft 206 drives the medicine placing turntable 207 to rotate, so that the extracted medicine bottle rotates to the discharge port 501. Due to the action of gravity, the medicine bottle detaches from the medicine placing box 2.

[0038] Furthermore, the steering gear 905 drives the lever 906 to toggle the toggle bar 907, so that the rotating ring plate 902 resets, and the clamping plate 904 rotates around the hinge rod 903, causing the end edge of the clamping plate 904 to disengage from the side of the syringe piston rod. At the same time, the injection tube support pier 11 unlocks the injection tube, and the user takes out the syringe that has completed the liquid extraction. This device only requires the user to manually place the syringe into the injection tube support pier 11 in the guiding sleeve 4, thereby automatically piercing and extracting the medicine bottle with the syringe. When facing a large number of liquid extractions, compared with manual insertion and extraction of the liquid medicine, the overall liquid extraction time is shortened.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
