Claims

[Scope of Claim for Utility Model Registration] (1) Woodworking in which a cutter having replaceable engagement positioning parts in axial grooves carved at several locations on the same circumference is fixed by a centrifugal fixing plate. In the mechanical planer barrel, the groove includes a first side wall, a second side wall that faces the first side wall and is inclined in a direction in which the opening becomes narrower, and serves as a contact reference surface for the cutter, and a second side wall to which the cutter is fixed. a bottom portion provided with an engaging jaw portion that also serves as a reference surface for determining the amount of protrusion of the blade when the blade is pressed; The engaging part has an engaging part on a side surface that also serves as a positioning part corresponding to the back engaging part, and has a flange part on the lower end that is held and held by the engaging jaw part and is positioned, and also serves as a positioning part of the cutter. a backing plate whose opposite side is the abutting surface of the centrifugal fixing plate; a spring that presses the flange of the backing plate against the jaw; and a spring acting on the backing plate so as to expand the insertion space of the cutter. a centrifugal fixing plate that abuts the back seat and the first side wall; and a spring that biases the centrifugal fixing plate so as to push the centrifugal fixing plate radially outward;
A planer barrel for a woodworking machine, characterized in that a blade can be replaced in the width direction by pushing down a centrifugal fixing plate. (2) The planer barrel for a woodworking machine according to claim 1, further comprising a cutter holder protruding below the cutter positioning engagement portion of the back seat.
