With the arrangement, when in use, the flanging end part (namely the surface parallel to the end surface of the can) of the can is abutted against the top of the drive gear, then the rotating handle is rotated, so that the inner side of the can opener is abutted against the inner side of the flanging, and the can is clamped and radially fixed with the outer side wall of the drive gear; the cutting edge of the can opener is abutted against the top of the can and forms an up-down clamping with the driving gear to axially fix the can. After accomplishing above-mentioned clamping structure, the twist grip presses down press switch when compressing tightly the can, and at this moment, driving motor starts and drives drive gear and rotate, and under above-mentioned clamping structure effect, drive gear can drive the can along the can turn-ups and take place to rotate, and inside can opener can insert the can from the roof, accomplished the rotation back of round when the can is accomplished, has accomplished the uncork promptly, and the operation is very simple, convenient.

More preferably: be provided with spacing arm on the casing, the last pressure arm that is provided with of twist grip works as when twist grip pushes down press switch, spacing arm and pressure arm are located drive gear and can opener's both sides, and are located the drive gear top.

So set up, when processing can centre gripping, spacing arm can be in drive gear and the both sides of can opener with pressing the arm to support at the top of can, and drive gear within a definite time form stable triangle-shaped clamping structure, fix can fine, when making drive gear drive can rotate, can not take place to rock and deviate from the centre gripping between drive gear and the can opener.

More preferably: the pressure arm is a spring piece.

Due to the arrangement, the pressing arm has certain elasticity, so that the can be driven to rotate more easily while the fixing effect on the can is kept; simultaneously before pushing down press switch, can carry out centre gripping in advance to the can, and the completion continues to drive the twist grip after centre gripping in advance and rotates and make the pressure arm take place the deformation in the time, begins to press switch, makes the centre gripping of can easier.
