Description

Walnut grafting scion grafting cutter

Technical field

The present invention relates to a kind of scion grafting cutter, the scion grafting cutter especially used during walnut grafting.

Background technology

Theoretically, what every branch section with 1 or several bud did that scion carries out grafting is called scion grafting.Scion used by scion grafting mostly is the branch of rest period, so typically all carrying out in spring, and is used for the stock that grafting is thicker, and it is more difficult than bud grafting to operate, but it is fast to look after connecing, and minority the most just can seedling or result.Scion grafting selects the diameter of stock to be usually 2～12 centimetres.The method of scion grafting is a lot, can be divided into cut-grafting, cleft grafting, side grafting, be abutted against, splice grafting, bridge joint, notch graft etc..Cut-grafting, cleft grafting and side grafting it is most commonly used that in production.Wherein, cut-grafting scion should select 7 cm long, has 2-3 full bud.The method of cutting of scion, first cuts the straight long bevel of a length 3 centimetres at terminal bud with side lower part, and the reverse side at this bevel cuts a short bevel again.After having cut scion, rapidly stock is cut off away from ground 5 centimeters, tilt to cut slightly inwards at its side scion grafting cutter, long equal with the long bevel of scion.The long bevel of scion is by inner, and short bevel is outer, inserts stock otch, and cambium layer is directed at.Accordingly, it would be desirable to complete to cut with scion grafting cutter, split, cut, cut, the step such as choose.

" Multi-purpose knife for fruit trees " patent (application number: 98214595.0) that Chinese patent CN2378916Y is disclosed, blade inswept, rear end width, blade one side is plane, another side be radius R1 be the arcwall face of 420-450 millimeter, 5 millimeters of blade thickness, cutting edge is an edge of a knife, and edge grinding is in the one side of band arc, and radius R2 is 85-95 millimeter, R3 is 60-75 millimeter, having sawtooth at the back side of blade front end, the latter half of radius R4 at the back side is 80-90 millimeter, long 70 millimeters of knife back saw, blade is fixed on handle, and centre is surrounded by latch closure iron sheet.This patent is disadvantageous in that: blade one side for plane, another side be radius R1 be the arcwall face of 420-450 millimeter, 0.5 centimetre of blade thickness, this structure bulky, be unfavorable for smooth long bevel, scion grafting is inefficient；For the stock of a diameter of 3～12 centimetres, radius R2 is that the circular arc cutting edge of 85-95 millimeter bends very much, it is impossible to is fully contacted stock appearance cortex and affects cutting, affects cutting efficiency when carrying out stock crosswise cutting operation；The back side has sawtooth, is unfavorable for that thumb force pressurizes when holding, and does not therefore reach easy to operate and requirement efficiently.

" Multi-function grafting knife " patent (application number: 200720083171.0) that Chinese patent CN201008280Y is disclosed, including handle and cutter, the afterbody of cutter is fixed on handle, and what cutter was anterior is sharp blade, and the another side knife back of cutter front portion is provided with sawtooth.This patent is disadvantageous in that: the knife back is provided with sawtooth, is unfavorable for that thumb force pressurizes when holding, and does not therefore reach easy to operate and requirement efficiently.

Summary of the invention

Present invention aim to provide a kind of walnut grafting scion grafting cutter, improvement of cutter structure so that it is be more suitable for walnut scion grafting, improve scion grafting efficiency.

In order to achieve the above object, the walnut grafting scion grafting cutter that the present invention provides is made up of handle of a knife and blade, wherein, handle of a knife is manufactured by metal or other hard materials, and the cross section of handle of a knife is circular, handle of a knife length 9～10 centimetres, shank diameter 1.8～2 centimetres, handle of a knife is the shortest or the most carefully can affect assurance steadiness, and handle of a knife is oversize or too slightly then hinders operation, this shape personnel convenient to operate palm when held of handle of a knife, easy to operate, sensitive, quick；Blade length 6.8～7.1 centimetres, blade is wide 1.5～1.6 centimetres, thick 0.28～0.3 centimetre of blade, and blade is the shortest or too narrow or the thinnest robustness that can reduce blade and operating efficiency, and blade is oversize or the widest or the thickest, affects the accuracy of operation；Two sides of blade are parallel, are beneficial to quickly cut out the long bevel of scion and the introversion inclined-plane of short bevel and stock；One end of blade is fixed on handle of a knife end face, point of a knife is trapezoidal, trapezoidal upper hem width 0.5 centimetre, this shape of point of a knife rapidly and will not damage cambium layer, then affects motility and the accuracy of operation when carrying out that stock is longitudinally cutting, choose skin and opening the operation of bleeding mouth when the width of trapezoidal top is more than or less than 0.5 centimetre；There is an oval end finger torr side of the knife back, the side of end finger torr is straight flange, straight flange is fixed by welding in the side of the knife back, end finger protracts 1.6～1.8 centimetres, end finger torr is wide 0.5～0.7 centimetre, end finger torr thickness is consistent with blade thickness, end finger torr is the shortest or too narrow or the thinnest robustness that can reduce end finger torr and the effectiveness of operation, end finger torr is oversize or the widest or the thickest, and seem the heavy and motility of impact operation, while this structure of end finger torr can not only quickly cut out the long bevel of scion and the introversion inclined-plane of short bevel and stock not affecting blade, increase thumb and carry out the dynamics of cutting operation, thumb can also be prevented plowing from；The cross section of the edge of a knife is inclined tooth shape shape, i.e. a side of blade deflection blade, and the inclined tooth shape shape of blade is convenient and swift when choosing skin, opening bleeding mouth and intercept bud sheet.When the invention is employed, operator hold handle of a knife with finger, carry out every scion grafting operation flexibly, and thumb is pressed in end finger torr, it is possible to strengthen the dynamics of cutting operation.

The walnut grafting scion grafting cutter that the present invention provides has positive effect: be made up of handle of a knife and blade, wherein, handle of a knife length 9～10 centimetres, shank diameter 1.8～2 centimetres, blade length 6.8～7.1 centimetres, blade is wide 1.5～1.6 centimetres, thick 0.28～0.3 centimetre of blade, point of a knife is trapezoidal, trapezoidal upper hem width 0.5 centimetre, there is an oval end finger torr side of the knife back, the side of end finger torr is straight flange, and straight flange is fixed by welding in the side of the knife back, and end finger protracts 1.6～1.8 centimetres, end finger torr is wide 0.5～0.7 centimetre, simple in construction；During use, operator operator hold handle of a knife with finger, carry out every scion grafting operation flexibly, thumb is pressed in end finger torr, the dynamics of cutting operation can be strengthened, it is greatly improved scion grafting efficiency and survival rate, facts have proved and can improve scion grafting efficiency more than 150%, it is adaptable to the trees scion grafting more than 2 centimetres of walnut scion grafting or other diameter of stock.
