Summary of the invention

The utility model be devoted to solve in prior art due to perching knife adopt hilted broadsword sword and can only one-way only operation to root out attachment, efficiency comparison is low, and the shape of cutting edge is single, to the imperfect defect of the elimination effect of different attachments.Aim to provide one can increase work efficiency, good to the elimination effect of different attachment, easy to operate a kind of perching knife that can remove rubbish back and forth.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: a kind of perching knife that can remove rubbish back and forth, comprise blade, handle of a knife and sleeve, cutter is provided with above described blade, one end of cutter is provided with the hook-shaped edge of a knife after bending, the described hook-shaped edge of a knife and cutter form the angle of 20 degree to 40 degree, the bending place of cutter and the distance of blade are 40 millimeters to 70 millimeters, bottom knife is provided with below described blade, one end of bottom knife is provided with the hook-shaped edge of a knife after bending, the described hook-shaped edge of a knife and bottom knife form the angle of 30 degree to 60 degree, the bending place of bottom knife and the distance of blade are 20 millimeters to 50 millimeters, what described handle of a knife was positioned at described sleeve place is axially arranged with the insert groove that cross section is rectangle structure, described cutter, the afterbody phase poststack of blade and bottom knife and insert groove suitable, the radial direction that described handle of a knife is positioned at sleeve place is provided with through stepped hole, step-like holding screw is provided with in stepped hole, the other end of stepped hole is provided with hexagon counterbore, counterbore is embedded with the hex nut with holding screw adaptation, can easily to blade, cutter and bottom knife fastening or remove fastening, also can separately or whole more allowing blade replacement easily, cutter and bottom knife, operation is very easy, the attachment that blade comes on place cleaning is utilized when hand is pushed ahead, when hand is to utilizing cutter or bottom knife to carry out the removing of attachment when pulling back, operating efficiency is improved a lot, the edge of a knife hook-shaped from bottom knife due to the edge of a knife that cutter is hook-shaped is different relative to the angle of blade respectively, make cutter different from the rigidity of bottom knife, can obtain there is different elimination effect to different attachment when cutter or bottom knife work, operationally, both different attachments can be removed, the hand of handle is made again to touch work plane.

As preferably, the afterbody of described blade, cutter and bottom knife be equipped with at least 2 with the locating hole of holding screw adaptation, like this can be fastening to blade, cutter and bottom knife or remove fastening easily, also can the position of independent or whole adjustable blade, cutter and bottom knife easily, the length of stretching out due to blade, cutter or bottom knife is different and the rigidity of blade, cutter or bottom knife is had greatly changed, to different attachment can remove better.

As preferably, the cutting edge of described blade is in-line or square dentation, and attachment can first be removed to strip by the cutting edge of the side's of employing dentation, and the cutting edge of convenient cutter below or bottom knife will remain attachment removing, directly can certainly adopt a word edge of a knife.

As preferably, the length of sleeve is 35 millimeters to 50 millimeters, makes handle of a knife have enough intensity.

Owing to adopting technique scheme, the beneficial effect of a kind of perching knife that can remove rubbish back and forth that the utility model provides is: 1. increase work efficiency; 2. the elimination effect of pair different attachment is good; 3. easy to operate.
