4 the needle advancing and retreating motor 36 of the automatic needle advancing and retreating mechanism 3 starts to operate, drives the reciprocating rod 34 to rotate, drives the pushing block 33 to move forwards, and a pushing connecting part on the pushing block 33 drives the injection driving mechanism 4 to move forwards, so that an injection assembly 5 arranged at the front end of the injection driving mechanism 4 moves forwards integrally, at the moment, a needle 51 extends out of a needle hole at the front end of the shell and penetrates into the skin to a set depth, and then the injection motor 40 stops operating;
5, the injection motor 40 of the injection driving mechanism 4 starts to operate, and drives the motor transmission shaft 44 to rotate, so as to drive the screw rod fixing sleeve 46 and the screw rod 47 to rotate; the screw rod 47 rotates and is guided by the nut 49 to move forwards relative to the screw rod fixing sleeve 46, and the driving pushing block 48 pushes the rubber plug in the clamping bottle 13 to move forwards, so that the liquid medicine is injected into a human body;
6, when the injection of the liquid medicine is finished, the injection motor of the injection driving mechanism 4 runs reversely, and the pushing block 48 is driven to automatically retract to the initial position;
7 the needle advancing and retreating motor 36 of the automatic needle advancing and retreating mechanism 3 is operated reversely to drive the injection driving mechanism 4 to move backward, so that the whole injection assembly 5 arranged at the front end of the injection driving mechanism 4 moves backward, and at this time, the needle 51 is retracted by the needle hole at the front end of the housing.
The present invention is not limited to the above embodiments, but is intended to be within the scope of the present invention as long as the technical effects of the present invention can be achieved by any same or similar means.
