[0032] Specific working principle:

[0033] The utility model provides a protective cylinder 8. When there is no need to inject, it only needs to push the protective cylinder 8 to move the movable pin 10 to the position of the connecting groove 6 and then rotate the protective cylinder 8. After the movable pin 10 moves to the other end of the connecting groove 6, the protective cylinder 8 is released. Under the push of the first spring 11, the movable pin 10 is clamped in the clamping groove 7. The clamping groove 7 limits the rotation of the protective cylinder 8, so that the protective cylinder 8 keeps covering each injection needle 4 to prevent the injection needle 4 from stabbing the medical staff. When it is necessary to inject, it only needs to push the protective cylinder 8 again, and then rotate the protective cylinder 8 in the opposite direction to make the movable pin 10 return to the slide groove 5, and then push the protective cylinder 8 to make the movable pin 10 move to the top of the slide groove 5. In this process, the limiting block 16 set on the top of the fixing member 15 passes over the limiting groove 13 and is engaged with the limiting ring 12, thereby fixing the protective cylinder 8, so that the syringe keeps extending from the inner side of the through hole 9, which is convenient for anesthesia injection to the patient.
