Description
Technical field
The utility model belongs to garden tool set technical field, be specifically related to a kind of simple in structure, the special saw of the seedling grafting with anti-binding function being easy to implement.
Background technology
Graft technology is the basic fundamental means of plant species improvement, grafting new varieties on veteran or other kind stocks, the even sprout of other kinds, utilizes the root system of stock and trophic system as growing nutrient base, impel shoot Fast Growth, reach the object of fast breeding.Not only be conducive to shorten the cycle of breed breeding, be more conducive to the hybridization of strain, improve the quality of new varieties, improve the characteristic of fruit or flowers, improve output capacity.Grafting is divided into cleft grafting, cut-grafting, be abutted against etc., no matter adopt which kind of grafting method, as the grafting tool branch saw instrument that is absolutely necessary, the butt of stock and shaping are all left branch and sawed, and also usually replace with carpenter's saw.Timber as its sawing of carpenter's saw is all dried, there is no the secretion of moisture and myron, sawing is lighter, lumber fibre is easily by neat blocking, and because sawtooth is all left and right staggered abduction, the sawing seam of self-assembling formation is wider, is greater than the thickness of saw blade, can not produce the phenomenon of the stagnant saw blade of folder.Fruit-tree grafting or Potted Landscape Modelling grafting, sawing be all fresh and alive limb, due to the secretion of moisture and myron, not only xylem fibre is difficult for being truncated, and is mostly to tear disconnectedly, must cause the cross section of sawing irregular, irregular xylem fibre broken end is collected in sawing seam, must cause the narrow of sawing seam.Meanwhile, myron and moisture cause saw blade surface viscous, and the effect of two aspects causes binding phenomenon, and major injury sawtooth.While dispatching from the factory, the sawtooth abduction part of processing is polished, and sawing process cannot form nature and expand gap effect, must cause binding phenomenon more serious, and workman, in the time of operation, can only pull at, careless slightly, can fracture by saw blade, but also may injure personnel.For this reason, develop one simple in structure, have nature and expand gap function, the special saw of the seedling grafting with anti-binding function of effectively avoiding binding phenomenon to occur is the effective way addressing this problem.
Utility model content
The purpose of this utility model is to provide a kind of development a kind of simple in structure, the special saw of the seedling grafting with anti-binding function of effectively avoiding binding phenomenon to occur.
The purpose of this utility model is to realize like this, comprise saw blade and saw handle, described saw blade and saw handle are by lock-screw immovable fitting, sawtooth on described saw blade interlocks to both sides abduction, the Thickness Ratio of the sheet body portion of the maximum ga(u)ge of sawtooth portion and saw blade is 1:0.5 ~ 1, on described sawtooth, buckling groove is set, described saw blade coordinates with the clamping of expansion gap device by buckling groove.
The utility model adopts the mode that expands gap device is set on saw blade, makes saw blade possess expansion gap function.In sawing process, except the expansion gap of sawtooth self-assembling formation, by expanding gap device, sawing gap to be widened, the xylem fibre of amputation simultaneously breaks end, and avoids myron and the moisture viscous saw blade of secretion, makes sawing more smooth, smooth.The utility model is simple in structure, be easy to implement, one or more expansion gap devices can be set as required, while needs or wearing and tearing can freely take off or change, do not affect the normal usage function of saw blade, be particularly useful for the occasion such as fruit tree or Potted Landscape Modelling grafting, overcome prior art branch and sawed the drawback that easy binding damages, contribute to reduce production costs, improve the safety of workman's grafting operation.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but never in any form the utility model is limited, any change or the improvement done based on the utility model training centre, all belong to protection domain of the present utility model.
As shown in Fig. 1 ~ 5, the utility model comprises saw blade 1 and saw handle 2, described saw blade 1 and saw handle 2 are by lock-screw immovable fitting, sawtooth 11 on described saw blade 1 interlocks to both sides abduction, the Thickness Ratio of the sheet body portion of the maximum ga(u)ge of sawtooth portion and saw blade 1 is 1:0.5 ~ 1, it is characterized in that, on described sawtooth 11, buckling groove 12 is set, described saw blade 1 at least arranges one and expands gap device 3.
Described expansion gap device 3 is " n " shape, and both sides arrange edge 32, and its inside arranges edge clipping 31, by coordinating fastening being arranged on saw blade 1 with buckling groove 12 clampings.
