<p>A can opener (100) has two pivotable handle members (110 & 120) and a traction wheel (200) and a rotary cutter (300) movable by the handle members (110 & 120) respectively between an inoperative position in which the wheel (200) and cutter (300) are spaced apart for mounting onto a can and an operative position in which they are close together for turning and cutting the can. An operating lever (400) is pivotable back and forth. A first ratchet assembly (510) is driven by the lever (400) upon pivotal movement in one direction for rotating the wheel (200) in one direction. There is also a second ratchet assembly (520) driven by the lever (400) upon pivotal movement in the opposite direction for rotating the wheel (200) in the same direction, whereby upon said pivotal reciprocation the lever (400) rotates the wheel (200) in the same direction to operate the wheel (200) and cutter (300) continuously to turn and cut the can.</p> |
