Abstract
The utility model relates to a fruit tree grafting equipment specifically is a special ring grafting device of pear tree. It includes handle of a knife (1) and sets up tool bit (2) at handle of a knife (1) front end, its characterized in that: handle of a knife (1) rear end be equipped with ring (3), its tool bit (2) comprise concave surface section (201) and the section of facing directly (202), and concave surface section (201) be located handle of a knife (1) near -end, the section of facing directly (202) are located handle of a knife (1) distal end. Its beneficial effect lies in: simple structure, can wear on the finger at the grafting in -process, cutting promptly is convenient, it is nimble to use always, and the grafting personnel can be in the cutting with get seedling, interface laminating and operation room such as fixed is changed rapidly.
Description
Technical field
The utility model relates to the technical field of fruit-tree grafting equipment, is specially the special finger ring device for grafting of a kind of pear tree.
Background technology
Insert skin tongue grafting be a kind of method common in fruit-tree grafting, particularly apricot tree, pear tree " branching grafting " grafting procedures in, insert skin tongue grafting be topmost method of operating.The lower end of scion to be whittled into the horse ear shape of plagioclase during concrete operations, be about 5 ~ 8 centimetres, insert stock upper end-face edge cortex and wooden between.Because apricot tree, pear tree current-year branch are relatively thicker, diameter is about 1.2 ~ 2 cm, therefore the grafting part rugosity of stock will between 3 ~ 8 centimetres.
A wide plane of 1.5 ~ 2 centimetres with facing the scion inclined-plane that cutter cuts out directly, and be a cylindrical curved surface with the stock position of this plane contact, the combination of plane and curved surface can make the both sides of faying face leave space, and this is very unfavorable to the healing of grafting interface.In order to make the rounded outer surface on scion inclined-plane and stock combine closely, the plane of the long horse ear shape of scion chamfered portion must be whittled into concave surface with grafting knife by skilled worker master workers.During operation, left hand grip fringe bar, the right hand takes cutter to exert oneself to dig quarter, and the direction of exerting oneself directs at left hand tiger's jaw, in an unguarded moment, point of a knife will stab left hand, in real work, the phenomenon of stabbing hand often occurs, and with point of a knife carve the groove surfaces scraped out coarse can't bear, reduce the survival rate connecing and transfer.Application number be 201220453004.1 utility model patent solve the problems referred to above, but owing to needing constantly to get seedling, cutting, interface laminating and fix in grafting operation process, blade is repeatedly placed and is picked up, not only reduce grafting efficiency, and be easy to pollute blade, cause interface to pollute, reduce graft survival rate.Therefore for the problems referred to above we have developed a kind of structure simple, can be worn on finger in grafting procedures always, namely cut conveniently, use flexibly, and grafting personnel can cut with get seedling, interface fit and the special grafting knife with ring of fruit tree that operation room changes rapidly such as to fix.
Utility model content
The purpose of this utility model is for above-described problems of the prior art, there is provided a kind of structure simple, can be worn on finger in grafting procedures always, namely cut conveniently, use flexibly, and grafting personnel can cut with get seedling, interface fit and the special finger ring device for grafting of pear tree that operation room changes rapidly such as to fix.
In order to realize described object, the utility model specifically adopts following technical scheme:
The special finger ring device for grafting of a kind of pear tree, it comprises handle of a knife 1 and is arranged on the cutter head 2 of handle of a knife 1 front end.It is characterized in that: described handle of a knife 1 rear end is provided with finger ring 3, its cutter head 2 is made up of concave surface section 201 and the section of facing directly 202, and concave surface section 201 is positioned at handle of a knife 1 near-end, and the section of facing directly 202 is positioned at handle of a knife 1 far-end.
Described concave surface section 201 is in circular arc.
Be provided with screw thread 4 on described handle of a knife 1, near finger ring 3 place, and be connected with protective cover 5 with screw thread 4.
Compared with prior art, the beneficial effects of the utility model are: one, described handle of a knife 1 rear end is provided with finger ring 3, it can be worn on finger in grafting procedures always, namely cut conveniently, use flexibly, and grafting personnel can cutting with get seedling, interface fit and the operation room such as to fix and change rapidly; Two, cutter head 2 is made up of concave surface section 201 and the section of facing directly 202, and its safety in utilization is good, connect that to transfer survival rate high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
In figure: handle of a knife 1, cutter head 2, finger ring 3, screw thread 4, protective cover 5, concave surface section 201, the section of facing directly 202.
Embodiment
Below in conjunction with accompanying drawing 1, accompanying drawing 2, structure of the present utility model and beneficial effect thereof are further illustrated.
Embodiment 1
The special finger ring device for grafting of a kind of pear tree, as shown in Figure 1, it comprises handle of a knife 1 and is arranged on the cutter head 2 of handle of a knife 1 front end.Its cutter head 2 is made up of concave surface section 201 and the section of facing directly 202, and concave surface section 201 is positioned at handle of a knife 1 near-end, and the section of facing directly 202 is positioned at handle of a knife 1 far-end.
Described concave surface section 201 is in circular arc.
Be provided with screw thread 4 on described handle of a knife 1, near finger ring 3 place, and be connected with protective cover 5 with screw thread 4.
When carry out interface laminating, fixing and get the operations such as seedling time without the need to taking, make grafting personnel can cutting with get seedling, interface fit and the operation room such as to fix and change rapidly.
During use, first protective cover 5 is extractd, finger ring 3 is with on forefinger or middle finger, then when scion is cut in grafting, first by the section of facing directly 202, scion is whittled into required size and shape, by concave surface section 201, bevel place is whittled into groove type again, power thrusts is outside along fringe bar, this just fundamentally avoids the generation of stabbing hand phenomenon, ensure the safety of operating personnel, meanwhile, the concave surface that fringe bar utilizes the concave surface section 201 of cutter head 2 to cut out is level and smooth, make it to combine closely with the outside of stock, improve the survival rate connecing and transfer.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
