[0045] The outer sleeve 4 is located in the middle position of the sleeve 3, and the outer sleeve 4 is rotatably connected to the sleeve 3. In this embodiment, through the above design, the outer sleeve 4 can be clamped with the mouth of the medicine bottle, which is convenient for fixing the dispensing device and the medicine bottle, and at the same time, it is beneficial for the sleeve 3 to drive the adjusting rod 5 and the movable rod 6 to rotate to mix the medicine liquid.

[0046] The number of outer sleeves 4 and adjusting rods 5 is the same, and the outer sleeves 4 and adjusting rods 5 are respectively located around the dispensing barrel 1. In this embodiment, through the above design, the medicine liquid can be stirred to make the medicine liquid mixed more evenly, thereby improving the dispensing work efficiency.

[0047] The puncture needle 2 is made of stainless steel, a baffle is fixed on the inner wall of the dispensing cylinder 1, and the puncture needle 2 is located at the center of the baffle. In this embodiment, through the above design, the position of the puncture needle 2 can be fixed, the corrosion resistance of the puncture needle 2 is increased, and the service life of the dispensing device is extended.

[0048] A power interface is provided on the outside of the shell 10, and the power interface is connected to the drive motor 11 through a wire. In this embodiment, through the above design, it is convenient for the shell 10 to be connected to the power supply, and then the sleeve 3 can be driven to rotate, so as to achieve the purpose of stirring the medicine solution.

[0049] The working principle of the present invention is as follows: when in use, first, the needle 19 is inserted into the interior of the medicine bottle through the handle 18, and the shell 10 is pushed to make the movable plate 9 move along the guide groove 16, and the shell 10 will drive the sleeve 3 to slide along the dispensing cylinder 1, so that the adjusting rod 5 and the movable rod 6 are located in the medicine liquid, and the connecting block 8 slides along the inner wall of the strip groove 7 to unfold the adjusting rod 5 and the movable rod 6. At this time, the outer sleeve 4 is engaged with the mouth of the medicine bottle to prevent the dispensing device from shaking, and then the driving motor 11 is started. Due to the meshing between the driving gear 12 and the driven gear 13, the driving motor 11 drives the driven gear 13 to rotate through the driving gear 12, so that the adjusting rod 5 and the movable rod 6 can rotate in the medicine bottle to mix the medicine liquid. After the mixing is completed, the regulating valve 15 is opened, and the medicine liquid is extracted through the dispensing tube 14. When the dispensing device needs to be taken out, the shell 10 is pulled upward to drive the sleeve 3 to move, so that the adjusting rod 5 and the movable rod 6 are in contact with the surface of the dispensing cylinder 1, and the medicine taking device can be pulled out of the medicine bottle.
