Summary of the invention
The present invention is devoted to solve in the prior art because perching knife adopts the hilted broadsword sword to root out attachment, and efficient is lower, and the shape of cutting edge is single, to the imperfect defective of removing effect of different attachments.Aim to provide a kind of can increasing work efficiency, effective to the removing of different attachments, cost-effective perching knife.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposals: a kind of multiple-cutting-edge perching knife, comprise blade, handle of a knife and sleeve, the top of described blade, the below is respectively equipped with cutter, bottom knife, cutter, the knife face of bottom knife and the angle of blade face are that 5 degree are to 15 degree, the length of cutter is lacked 40 millimeters to 70 millimeters than the length of blade, the length of bottom knife is lacked 20 millimeters to 50 millimeters than the length of blade, the cutting edge of blade and cutter, the edge width difference of bottom knife is less than 20 millimeters, described handle of a knife is positioned at the take the shape of the letter U blade bearing of groove structure of being axially arranged with of sleeve place, described cutter, the afterbody phase poststack of blade and bottom knife and the U-lag of blade bearing are suitable.When removing attachment, blade contacts work plane simultaneously with cutter or bottom knife, and blade is removed the major part of attachment earlier, the residue attachment by immediately following after cutter or bottom knife remove totally.
As preferably, the cutting edge of blade is in-line or side tooth profile, when the degree of adhering to 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, makes things convenient for the cutter of back or the cutting edge of bottom knife will remains 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, 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.
