A 180-deg swing mount (22,23) is fitted to the functional unit (16) to releasably and mutually locate the opener handles (24) using two abutted stub axles to form the mount or again two opposed insertion holes. In the case of a single handle, this can pivot through 180 degrees as fitted in the mounted provided, compared with the two-handle version (24) where these are mutually held by means of two legs (22,23) crossways to the function unit axis (17). The two-handle version uses a function unit (16) formed from two bearers (18,19) joined crossways by the axis. One bearer (18) carries the actuator (4) and feed wheel (3) as opposed to the other bearer (19) which carries the cutting wheel (20) and drive gear (21). |
