The present invention relates to a can opener which cuts a can automatically.
A conventional can opener contains a cutter fixed on a grip handle so as manually cut a can, but it is operated forcefully and difficultly.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a can opener in which a button of a first switch is pressed by a user to open a can automatically, and after opening the can, the can opener removes from the can automatically, thus opening the can easily.

The second driving gear 33 has a central column 37 disposed on a central position thereof and inserting into a central hole of the torsion spring S, and the second driving gear 33 also includes a plurality of connection apertures 38 formed thereon and configured to fix the eccentric gear 40.
The eccentric gear 40 includes an opening 41 corresponding to the central column 37 and configured to accommodate the central column 37, the eccentric gear 40 also includes a plurality of coupling pillars 42, and each coupling pillar 42 corresponds to and connects with each of the plurality of connection apertures 38, wherein the eccentric gear 40 is located beside the rotating roller 50.
The rotating roller 50 includes a second post 51 mounted on a central position thereof and rotatably connecting with one of the plurality of first posts 22, such that rotating roller 50 rotatably contacts with the eccentric gear 40.
The connector 60 includes a second arcuate orifice 61 corresponding to the first arcuate orifice 24 and configured to extend the central column 37 outwardly, a plurality of second coupling stems 62 corresponding to and coupling with the plurality of first coupling stems 27 of the second accommodation room 23, and two second positioning pillars 63, wherein each of the two positioning pillar 63 corresponds to and connects with each of the two first positioning pillars 28 of the second accommodation room 23.
The washer 70 includes a third arcuate orifice 71 corresponding to the first arcuate orifice 24 of the second accommodation room 23, and the washer 70 includes a fixing hole 72 defined on a front end thereof so as to accommodate a screw P and to screw with a screwing hole 74 of a shank 73, wherein the shank 73 rotatably connects with the guiding roller 80, and the metal piece 90 is fixed below the washer 70.
The guiding roller 80 includes a first pore 81 configured to accommodate the shank 73 and includes an abutting portion 82 configured to abut against a can 100.
The metal piece 90 includes a second pore 91 configured to extend the central column 37 outwardly and includes a contacting gear 92 coupled with a distal end of the central column 37 and configured to abut against the can 100.
