Then the first locking piece, the second locking piece and the third locking piece are unlocked, the next acupuncture angle selected according to needs is taken as a circle center, the syringe fixing barrel 5 is rotated according to a required rotation angle (namely, the syringe fixing barrel 5 is rotated to the state shown in figure 2) by taking the needle head (namely, the bottom of the syringe fixing barrel 5) of the syringe 12 as a circle center, then the calibration auxiliary rod 9 is adjusted to coincide with the syringe 12 at the moment, the calibration auxiliary rod 9 slides a distance (namely, the state shown in figure 3) along the direction of the calibration rod 8, then the sliding block 3 slides to the intersection point between the calibration auxiliary rod 9 and the supporting rod 2 (namely, the axis of the adjusting rod moves to the intersection point between the calibration auxiliary rod 9 and the supporting rod 2), at the moment, the extension line of the needle head of the syringe 12 can just pass through the acupuncture point, and then the first locking piece, the second locking piece and the third locking, the next syringe 12 is replaced and the health care provider slides the syringe 12 downward to pierce the needle of the syringe 12 into the skin of the patient's face just enough to allow the needle of the syringe 12 to reach the point exactly.

Example two

The difference between this embodiment and the first embodiment is: after the first injection is completed and the needle of the syringe 12 is pulled out of the facial skin of the patient, the whole syringe fixing barrel 5 is pulled upwards by a distance a, and the calibration auxiliary rod 9 slides on the calibration rod 8 by a distance a. The purpose of this operation is: when the sliding block 3 drives the syringe 12 to transversely slide, the bottom of the syringe fixing barrel 5 is prevented from contacting the face of a patient when sliding.

EXAMPLE III

The present embodiment is different from the first and second embodiments in that: after the first injection is completed, the needle of the syringe 12 is pulled out of the facial skin of the patient, and then the whole syringe fixing barrel 5 is pulled upwards by a distance a which is several times of the distance a, and the distance of the calibration auxiliary rod 9 sliding on the calibration rod 8 is also several times of the distance a.
