<p>An electrically powered can opener has a cutter wheel carried on a removable hand lever pivoted to the front surface of the upright can opener frame. An elongate pin extends from the hand lever through an elliptical opening in the front frame panel. The pin is engagingly retained in the upper half of the opening by a hinged latch member which is spring biased toward the rear surface of the front frame panel and pivotal away from the frame surface about its hinge axis. In a first embodiment, a control rod having a push button assembly extending through the frame is manipulated to pivot the latch rearwardly from engagement with the pin so that the hand lever may be detached from the frame. In a second embodiment, the control rod is replaced by a small pin slidably positioned in a bore in the front frame panel. The pivoting of the hand lever to an extreme position slides the pin rearwardly to pivot the latch away from the frame opening. In a third embodiment, the latch is mounted for limited vertical movement. Downward movement of the pin pushes the latch downwardly and positions the pin in the lower portion of the frame opening from where it may be withdrawn.</p> |
