Abstract:
1. A can opener, comprising: a housing having an interior provided with a mounting seat; a driving gear rotatably mounted on the mounting seat of the housing; a reduction transmission device mounted in the housing and connected with the driving gear to drive the driving gear, with the reduction transmission device including a drive motor; a cutting wheel rotatably mounted relative to the housing and rotated in concert with the driving gear; a slide movably mounted on the mounting seat of the housing and having a surface provided with an aperture; a washer secured on a bottom of the slide to move in concert with the slide; an idling wheel rotatably mounted on the washer and movable relative to the cutting wheel; a first driven gear rotatably mounted in the housing and meshing with the driving gear; a second driven gear rotatably mounted in the housing; a torsion spring biased between the first driven gear and the second driven gear to connect the first driven gear and the second driven gear; a third driven gear rotatably mounted in the housing and meshing with the second driven gear; and a cam mounted on and rotated by the third driven gear and received in the aperture of the slide to move the slide relative to the cutting wheel; wherein the second driven gear has a surface provided with an arcuate guiding slot; the first driven gear has a surface provided with a protrusion mounted in the guiding slot of the second driven gear; and when the first driven gear is rotated by the driving gear, the protrusion of the first driven gear is movable in the guiding slot of the second driven gear to drive and rotate the second driven gear and to compress the torsion spring so that the torsion spring stores a restoring force.
