[0028] Working principle: by putting a plurality of assembly pieces 23 into the hollow plate 21, the assembly pieces 23 here can be any structure required in the process of assembling the syringe. At this time, the assembly pieces 23 will be stacked in the hollow plate 21 in an inclined state. When the rotating disc 6 is driven to rotate by the motor 5, the position of the assembled syringe structure inside the rotating cover 7 can be adjusted.
