The practitioner can then use the anesthesia needle to practice acupuncture at the position located by the locator, thereby improving anesthesia techniques for better anesthesia treatment of women and children.

[0005] However, when an individual model is damaged, since the model is fixedly connected to the fixed rotating column, the damaged model cannot be quickly replaced, thereby reducing the replacement efficiency. Summary of the invention
