3. The automatic stopper-withdrawing bottle opener according to claim 1, wherein the driving mechanism is driven to rotate the rotary seat in a forward direction to cut the bottle mouth, and is driven to rotate the lifting mechanism in a reverse direction to drive the limiting shell to return to an upper position of the rotary seat.

4. The automatic plug-withdrawing bottle opener according to claim 3, wherein the lifting mechanism comprises a lifting plate extending upward to one side of the upper base along the limiting shell, a shell rotatably sleeved outside the upper base, a guide post penetrating and fixed on the shell, and a guide member disposed on the upper base; the guide piece provides an upward guide path for the guide pillar, the lifting plate is provided with a guide channel which is vertically distributed, and the guide pillar is movably embedded in the guide channel.

5. The automatic stopper-removing bottle opener according to claim 4, wherein the guide post abuts against an upper portion of the guide channel, and the driving mechanism rotates reversely to drive the guide post to move so as to lift the lifting plate.

6. The automatic stopper bottle opener according to claim 5, wherein the guide member is a guide slope provided around an outer wall of the upper base, the guide slope having a guide path provided spirally upward; the guide slopes are arranged in a plurality and are distributed at equal intervals; the driving mechanism rotates reversely to enable the guide post to spirally ascend along the guide slope; the driving mechanism rotates positively to make the guide post descend spirally along the guide slope.

7. The automatic stopper bottle opener according to claim 6, wherein an annular flange is provided around the upper base, and a buffer member is provided between the lower end surface of the shell and the annular flange.

8. The automatic plug-removing bottle opener according to claim 7, wherein the buffer member comprises a plate body supported on the lower end surface of the shell and a plurality of columns arranged on the lower end surface of the plate body, the annular flange is provided with through holes matched with the columns, the columns are sleeved with springs, and two ends of each spring are respectively connected with the plate body and the annular flange.

9. The automatic stopper bottle opener according to claim 1, wherein a plurality of protrusions are provided on a side surface of the stopper body, a concave groove adapted to the protrusions is provided inside the rotary seat, and the stopper body slides up and down along the concave groove.

10. The automatic plug-removing bottle opener according to claim 1, wherein a limiting block is arranged at a lower end of an inner side of the swing arm in an inward protruding manner, the plug body abuts against a side face of the swing arm in an initial state, and the limiting block abuts against a lower end face of the plug body to limit the plug body from being separated from the accommodating cavity.
