Thus, the needle can be retracted into the barrel after use, thereby preventing the user or other person from being hurt by the protruding needle, so as to provide a safety effect. In addition, the plunger can be broken, so that the needle is stored in the barrel, thereby achieving the safe and sanitary effect.
