[0040] In the present invention, the starting end of the plastic bag passes through the through hole on the left side of the device body 1. After the motor is started, the driving shaft 41 is coaxially driven to rotate half a circle, which also drives the bag-taking wheel 42 to rotate half a circle. After the bag-taking wheel 42 rotates, the lever 4202 is lifted upward. The lever 4202 touches the left panel of the device body 1 and then automatically falls back. The lever 4202 moves the connecting frame 701. When the lever 4202 completes a reciprocating movement of rising and falling, the cutting knife 7 is driven by the connecting frame 701 to complete a cutting action.

[0041] When the bag taking wheel 42 rotates, it contacts the sponge 501, so that the outer surface of the bag taking wheel 42 is dipped into a little water. When taking out smooth bags such as plastic bags that are easily charged with static electricity, it is easy to twist them open, thereby improving the subsequent bag opening speed.
