Abstract

It the utility model is related to fruit-tree grafting equipment technical field, and in particular to fruit grafting knife with concave surfaces.A kind of to include facing section and concave surface section directly with fruit grafting knife with concave surfaces, including cutter head and the handle for being arranged on cutter head end, the cutter head, the front faced section directly and be located at concave surface section, the section of facing directly is in triangle knife face, and ellipse arc is presented in the concave surface section；The side oblique weld of the handle sets finger ring, and auxiliary handle is vertically arranged on the finger ring side.The utility model is simple in construction, and right hand forefinger or forefinger and middle finger are stretched on finger ring when use, and other remaining fingers hold auxiliary handle simultaneously, and thumb pins handle；When cutting fringe, first the blade first rough shapes and sizes that scion is whittled into needs can be faced directly with face section directly, then it is whittled into the groove surface of bending with the bending blade of concave surface section, power thrusts are not directly to left hand, for " plane " of certain bending amplitude, direction firmly is back to left hand, can so avoid left hand from being scratched.

Description

With fruit grafting knife with concave surfaces

Technical field

It the utility model is related to fruit-tree grafting equipment technical field, and in particular to fruit grafting knife with concave surfaces.

Background technology

It is a kind of method common in fruit-tree grafting to insert skin tongue grafting, specifically, being whittled into the lower end of scion tiltedly during operation Long horse ear shape, is about 5-8cm, the cortex of insertion stock upper end and it is wooden between, then by being finally fixed scion and bag Prick.Because the scion inclined-plane cut out with straight knife is the circular outside close contact of one and stock, but fringe is oblique in real process Face is easily processed, and causes worker's needs cutting repeatedly to change, and when operation, left hand holds fringe, and the right hand is firmly cut groove, easily led Left hand is scratched in cause, and cutter of the prior art is common pocket knife, and handle and blade cause to use in same straight line, this design Power is uneven, and the blade near handle is often used when use.

Utility model content

In order to solve above-mentioned prior art problem, the utility model is provided with fruit grafting knife with concave surfaces, Ke Yigai The deficiency of the kind above.

It the utility model is related to fruit grafting knife with concave surfaces, including cutter head and the handle for being arranged on cutter head end, institute Stating cutter head includes facing section and concave surface section directly, and the front faced section directly and be located at concave surface section, the section of facing directly is in triangle knife face, described Ellipse arc is presented in concave surface section；The side oblique weld of the handle sets finger ring, and auxiliary is vertically arranged on the finger ring side Handle.

Further, connecting rod is set between finger ring and the angle of handle, and the both ends of the connecting rod are respectively protruding into finger The inside of ring and handle.

Further, there is bending blade in the concave ends of cutter head；The width of the bending blade to the knife back is different, leans on The width of the side of nearly handle is less than the trend of the width, generally continuous gradation that are contacted with facing section directly, bends the blade of blade Cutting edge of a knife or a sword mouth is indent form.

Further, the auxiliary handle shank is passing straight through the contact position of the center of circle of finger ring and finger ring and handle.

Further, the material of the cutter head is manganese steel.

The utility model is simple in construction, and it is novel to improve, and right hand forefinger or forefinger and middle finger stretch into finger ring when use On, other remaining fingers hold auxiliary handle simultaneously, and thumb pins handle；When cutting fringe, first blade can be faced directly with face section directly The first rough shapes and sizes that scion is whittled into needs, are then whittled into the groove surface of bending with the bending blade of concave surface section, use Force direction is not directly to left hand, and is " plane " of certain bending amplitude, and direction firmly can be so kept away for back to left hand Exempt from left hand to be scratched.

Brief description of the drawings

Fig. 1 is the utility model structure diagram.

Fig. 2 is that the utility model overlooks face structural representation.

Fig. 3 is concave surface section flattened structure schematic diagram.

1 face directly section, 11 face directly blade, 2 concave surface sections, 21 bending blades, 3 handles, 4 finger rings, 5 connecting rods, 6 auxiliary handles.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with the accompanying drawings and implement Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is used only for explaining The utility model, it is not used to limit the utility model.

As depicted in figs. 1 and 2, with fruit grafting knife with concave surfaces, including cutter head and the handle 3 for being arranged on cutter head end, The cutter head includes facing section 1 and concave surface section 2 directly, and material is manganese steel, the front faced section 1 directly and be located at concave surface section 2, described to face directly Section 1 is in triangle knife face, and ellipse arc is presented in the concave surface section 2；The side oblique weld of the handle 3 sets finger ring 4, the finger Auxiliary handle 6 is vertically arranged on the side of ring 4, the shank of auxiliary handle 6 is passing straight through the center of circle of finger ring 4 and finger ring 4 and handle 3 Contact position, finger ring 4 and auxiliary handle 6 are the position of four fingers firmly, and particularly, right hand forefinger or forefinger and middle finger stretch into finger On ring 4, other remaining fingers hold auxiliary handle 6 simultaneously, and thumb pins handle 3；In order to strengthen between finger ring 4 and handle 3 Stability, connecting rod 5 is set between the angle of finger ring 4 and handle 3, and the both ends of the connecting rod 5 are respectively protruding into finger ring 4 and hand The inside of handle 3.

There is bending blade 21 in the concave ends of cutter head；The width of the bending blade 21 to the knife back is different, close to handle 3 The width of side be less than the trend of width, generally continuous gradation contact with facing section 1 directly, the blade cutting edge of a knife or a sword mouth of bending blade 21 For indent form (as shown in Figure 3), Fig. 3 is the flattened structure schematic diagram of concave surface section 2, interior recess (line segment is filled in Fig. 3) here It is mainly to put forth effort position when in use.When cutting fringe, first it can face that blade 11 is first rough to cut scion directly with face section 2 directly Into the shapes and sizes of needs, the groove surface of bending then is whittled into the bending blade 21 of concave surface section 2, puts forth effort position as bending knife The blade cutting edge of a knife or a sword mouth of sword 21 is interior recess, and this positional distance finger ring 4 puts forth effort that position is nearest, and strength is maximum, cuts fringe maximum intensity；Such as Fruit is the bending blade 21 of concave surface section 2 and the width of the knife back is uniform thickness, according to practical operation, it is found that the strength that uses is bigger；With Force direction is not directly to left hand, and is " plane " of certain bending amplitude, and direction firmly can be so kept away for back to left hand Exempt from left hand to be scratched.

Found by practical operation, use in the utility model unique finger ring 4 and auxiliary handle 6 mainly to put forth effort position, by Certain angle is through in finger ring 4 and handle 3, the distance with force and blade and batten contact point is shortened, with prior art In handle of holding compare, labour-saving effect can be played, and be easier to cut fringe.
