Abstract

The utility model provides a grafting knife which belongs to the field of a fruit tree grafting tool. Engraving of an indentation which is similar with a fan is required in fruit tree grafting and wastes a large amount of time. For setting the defects in the prior grafting tool, the utility model provides the grafting knife with a fan-shaped edge, which has the following advantages: time saving, improved grafting efficiency, and simple operation. The technical solution for settling the technical problems provided by the utility model is characterized in that: the grafting knife comprises a knife handle (1); the grafting knife comprises a hollow pipe member (2) of which the cross section is fan-shaped; one end of the pipe member (2) is fixedly connected with the knife handle; the pipe member (2) is vertical to the knife handle (1); and the other end of the pipe member (2) is provided with the edge (3) with a fan-shaped cross section.

Description

A kind of grafting knife

Technical field

The utility model belongs to the garden instrument field, belongs to the fruit-tree grafting field of tool specifically.

Background technology

Fruit-tree grafting is a kind of method of cultivating improved seeds, and generally, this method has a step to do like this: carve next similar fan-shaped indentation with pocket knife around a bud of fruit tree branch, then, take off fruit tree skin with the fruit tree bud along indentation.This step loses time very much: carve this indentation, need extreme care careful.Simultaneously, utilize pocket knife to carry out this step, will prevent that also pocket knife slippage in sliding process from injuring staff.So, be necessary to create a kind of new instrument and carry out the operation of this step.

The utility model content

In order to solve the deficiency of instrument in the existing grafting, the utility model proposes a kind of grafting knife with fan-shaped edge of a knife, the utlity model has and save time, improve the advantage of grafting efficiency, also have advantage simple to operate simultaneously.

The technical scheme that the utility model technical solution problem adopts is: a kind of grafting knife, comprise handle of a knife, it is characterized in that: it is fan-shaped pipe fitting that a hollow and cross section is arranged, one end of pipe fitting is fixedlyed connected with handle of a knife, and pipe fitting is vertical with handle of a knife, and it is the fan-shaped edge of a knife that the other end of pipe fitting has the cross section.

The operation principle that the utility model adopts is: because will inscribe a slice roughly is fan-shaped fruit tree skin, so, can directly adopt the cutter that is fan-shaped to be carved into.

Embodiment

Below in conjunction with accompanying drawing, design and use of the present utility model are further specified.

Referring to accompanying drawing 1, be structural representation of the present utility model, handle of a knife 1 can adopt timber to make, and also can adopt rubber to make, and also can adopt metal to make, and the effect of handle of a knife 1 is to be convenient to grip.Pipe fitting 2 adopts stainless steel to make, and also can be made of copper.Pipe fitting 2 is hollow.Pipe fitting 2 belongs to prior art with the construction technology that handle of a knife 1 is fixedlyed connected, such as selecting bonding, riveted joint, welding etc. for use.

Referring to accompanying drawing 2, be end view of the present utility model, an end of pipe fitting 2 is fixedlyed connected with handle of a knife 1.

Referring to accompanying drawing 3, be vertical view of the present utility model, pipe fitting 2 is vertical with handle of a knife 1, and such design is convenient to grip, and is convenient to apply strength.

Referring to accompanying drawing 4, be the cross section of pipe fitting 2, this cross section is fan-shaped.

In order further to optimize the utility model, referring to accompanying drawing 5, be end view of the present utility model, the cross section of handle of a knife 1 is semicircle, She Ji advantage is like this: when staff gripped handle of a knife 1, handle of a knife 1 gripped more with palm and fits, and gripped to be difficult for skidding.

In order further to optimize the utility model, referring to accompanying drawing 6, be vertical view of the present utility model, the edge of a knife 3 is a circular arc caving in along the direction at pipe fitting 2 vertical places.She Ji advantage is like this: the most rounded cross section of fruit tree branch, it is the edge of a knife 3 of a circular arc that utilization is caved in, and more is conducive to inscribe fan-shaped bark.

Using method: grip handle of a knife 1 on the other hand, buttress branch on the other hand, press down facing to the position that need inscribe with the edge of a knife 3, if necessary, can rotate a little on vertical and plane, branch place, just can carve the next one and be fan-shaped indentation.Then, take off fruit tree skin with the fruit tree bud along indentation.

Various equivalent modifications should be known: the edge of a knife 3 has sharp edges, and the edge of a knife 3 sizes should be suitable for the required indentation size of fruit tree branch.

The utlity model has simple in structure, easy operating, time saving advantage.
