Preferably, the first driver is a micro cylinder, and the second driver is a screw motor.
The beneficial effects of adopting above-mentioned further scheme are that, the miniature cylinder action is rapid, the action of pricking the needle and pulling out the needle of realization syringe that can be better, and screw motor action is slow, and position control is accurate, and better realization is to the propelling movement and the absorption of medicament.
Preferably, the pre-packaged syringe comprises a syringe body and a pre-packaging tape, wherein the pre-packaging tape comprises a bag portion for accommodating the syringe body and a connecting portion for connecting adjacent bag portions; the injector body is arranged in the bag sleeving part in a penetrating mode and can move along the axial direction of the bag sleeving part.
The beneficial effect who adopts above-mentioned further scheme is that the syringe body can move up and down along the axis direction in the cover bag portion to when injection device drive syringe injected, can not drive the connecting portion action of prepackage belt, ensured the stable transportation of prepackage syringe.
Preferably, the injection delivery mechanism comprises a driving body and a transportation driver, the driving body is fixed on a rotating shaft, and the transportation driver drives the driving body to rotate around the shaft;
the driving body is provided with a containing groove, and the containing groove is matched with the shape of the injector body;
a limiting structure is arranged in the accommodating groove and used for limiting the moving range of the injector in the axial direction of the accommodating groove.
The beneficial effect who adopts above-mentioned further scheme is that the rotation of driving body can make the storage tank of locating on the driving body just hold the syringe body to based on the rotation of driving body, drive the whole forward of prepackage syringe, the interval of the last adjacent storage tank of driving body and the distance looks adaptation of adjacent bagging portion in the prepackage area, thereby can realize the continuous feed of prepackage syringe.
