DETAILED DESCRIPTION OF THE INVENTION

[0023] The technical solutions of the utility model will be clearly and completely described below in conjunction with the drawings and specific embodiments.

[0024] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, the utility model provides an electric-assisted medicine dispensing instrument, which includes a housing 1, a driving motor 2, a lead screw 3, a guide rod 4, a front and rear moving block 5, a piston slot A 6, a piston slot B 7, and a syringe slot 8.

[0025] Among them, the driving motor 2 is arranged at the lower front part of the housing 1; the lead screw 3 is horizontally arranged in the housing 1, and the front and rear moving block 5 is arranged on the lead screw 3. The front and rear moving block 5 is internally provided with a thread matching the lead screw 3; the guide rod 4 is horizontally arranged in the housing 1 and is parallel to the lead screw 3; the syringe slot 8 is arranged at the outlet end of the housing 1, and the top of the front and rear moving block 5 is provided with a piston slot A 6 and a piston slot B 7.

[0026] In this embodiment, a handle 9 is arranged at the lower rear part of the housing 1.
