As preferably, the cutting edge of blade is in-line or side tooth profile, when the adherence of the attachment of rooting out when needs is big, adopts the cutting edge of side tooth profile earlier attachment to be removed to strip, and the cutter of convenient back or the cutting edge of bottom knife will remain the attachment removing.
As preferably; Handle of a knife is positioned at the stepped hole that radially is provided with perforation at sleeve place; Be provided with soket head cap screw, pad in the stepped hole; The other end of stepped hole is embedded with nut, and the afterbody of blade, cutter and bottom knife is equipped with the hole adaptive with soket head cap screw, is provided with the through hole adaptive with soket head cap screw at the bottom of the U-lag of blade bearing.Blade, cutter and bottom knife are fastening or remove fasteningly so easily, also can change blade, cutter and bottom knife easily separately or all, and provide cost savings.
As preferably; Handle of a knife is positioned at the stepped hole that radially is provided with perforation at sleeve place; The other end that is provided with soket head cap screw, pad, stepped hole in the stepped hole is embedded with nut; The afterbody of blade is provided with the hole adaptive with soket head cap screw, and the length that the afterbody of cutter and bottom knife is provided with the waist hole adaptive with soket head cap screw, waist hole is 35 millimeters to 45 millimeters.Can regulate the cutting edge distance of blade cutting edge and cutter or bottom knife so easily, firmly keep optimum state when making blade and cutter or bottom knife and work plane fit work simultaneously.
As preferably, the length of sleeve is 25 millimeters to 40 millimeters, makes handle of a knife have enough intensity.
Because adopt technique scheme, the beneficial effect of a kind of multiple-cutting-edge perching knife provided by the invention is: 1. increase work efficiency; 2. effective to the removing of different attachments; 3. saving cost.
