摘要： There is a mechanism allowing a speedy and smooth inductive operation in XYZ directions with a guide post erected on a floor.A chopper casing is provided on the fore end of a thrust shaft being supported by said mechanism and being freely movable forewards and backwards. Wedge projections are provided on both sides of the casing. A pair of stanchions both project downward from each side of the chopper for positioning, space retaining and guiding for swing-down operation of a chopper.One end of the chopper is pivoted to the casing, other end thereof is left free and along the lower edge thereof provides a blade which reciprocates in vertical direction by an automatic driving means.A mechanism controlling accidental drop of the chopper is provided by attaching a rack and pinion, a ratchet and ratchet wheel.
