Align the rectangular opening 140 of the positioner at the eyebrow tip with the connecting barrel 120 of the positioner at the outer end of the infraorbital rim. Then pull out the flexible ruler 2, insert the connecting end 220 into the connecting barrel 120, rotate the rotating wheel 310 clockwise to straighten the flexible ruler 2 and stick it to the patient's skin, then rotate the knob 410 to make the fixing block 430 move downward and cooperate with the protruding protective shell 1 at the bottom end of the rectangular opening 140 to clamp the flexible ruler 2 and limit its movement. Then stick another positioner at the edge of the hairline in the horizontal direction of the eyebrow tip. Align the rectangular opening 140 of this positioner with the connecting barrel 120 of the positioner at the eyebrow tip. Connect the two positioners by the same operation. Stick a fourth positioner at the edge of the hairline in front of the ear to make its rectangular opening 140 align with the connecting barrel 120 of the positioner at the edge of the hairline in the horizontal direction of the eyebrow tip. Align the connecting barrel 120 of the fourth positioner with the rectangular opening 140 of the positioner at the outer end of the infraorbital rim. Connect them by the same operation. The quadrilateral area surrounded by the four positioners is the injection area.
