Multiple arc-shaped grooves are respectively provided on both sides of the plunger handle, and a scale line is processed on the front side of the plunger handle. A reminder mechanism and a quantitative mechanism are sleeved on the outer side of the plunger handle. The indicator arrow is located in front of the plunger handle, and the I-shaped block is connected to a thumb screw. The front side of the thumb screw is fixedly connected to a contact block, and the front side of the contact block is in contact with a back side of the plunger handle. The quantitative mechanism can make the injection dose of the syringe precise and controllable, while the reminder mechanism can remind doctors of the real-time injection amount during botulinum toxin injection.
