[0037] When the adjustment is completed, the needle 2 is inserted into the medicine, and then the push handle is pulled outward to drive the piston to suck the anesthetic into the syringe 1 through the needle 2. When the push handle is pulled outward to the adjusted dose, the short end of the fixed rod 7 conflicts with the extended end of the slider 502, thereby accurately controlling the extracted dose.

[0038] Then, when the adjustment is completed, the telescopic spring 802 can drive the fixing block 801 to clamp the outer wall of the first gear 504, so that the adjusted injection dose can be limited, thereby avoiding accidental changes during the extraction process and improving the stability of the anesthetic needle when in use;

[0039] When the injection dose needs to be adjusted, the pull block 805 is pulled outward to a certain distance, and the pull block 805 is rotated 180 degrees at this time, and one end of the stop block 806 is rotated to face the surface of the support block 803. Then, the pull block 805 is released, and the telescopic spring 802 rebounds and drives the stop block 806 to press against the surface of the support block 803, thereby maintaining the unlocked state of the fixing component 8, which is convenient for the anesthesiologist to adjust the injection dose. After the adjustment is completed, the first gear 504 can be fixed again by rotating it 180 degrees again, which is simple and convenient.
