The driving assembly comprises a threaded column 51 rotatingly installed on the inner wall of the track groove, a nut seat 52 slidingly installed on the inner wall of the track groove, and a motor 53 fixedly installed on the right side surface of the handle 20. The output end of the motor 53 extends to the inner wall of the track groove and is fixedly connected with the right end of the threaded column 51. The threaded column 51 is in screw transmission with the nut seat 52, and the upper surface of the nut seat 52 is fixedly connected with the lower surface of the pushing block 50. When the syringe plunger 12 enters the plunger placing groove 23, the left movement of the pushing block 50 can drive the pushing block 50 to push the syringe plunger 12 to enter the syringe barrel 10, thereby enabling the cosmetic liquid in the syringe barrel 10 to be discharged along the syringe needle 13.

[0040] The surface of the handle 20 is provided with a control switch 60 for driving the on-off of the motor 53, the inside of the handle 20 is provided with a battery 61 for supplying power to the motor 53, the motor 53 can be driven to rotate by the control switch 60, the threaded column 51 is driven to rotate after the motor 53 rotates, the threaded column 51 and the nut seat 52 are driven by the screw transmission, so that the push block 50 can be synchronously moved, and then the push block 50 can push the injection push rod 12 to inject the cosmetic liquid.

[0041] When another cosmetic liquid needs to be injected, the syringe is taken off from the handle 20 to replace a new syringe, so that the new cosmetic liquid can be injected, and the chemical reaction of the mixed cosmetic liquid of different components is avoided.

[0042] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application belong to the scope protected by the utility model.
