Description
Technical field
The invention belongs to garden tool set technical field, be specifically related to a kind of structure simply, the special saw of seedling grafting with anti-binding function be easy to implement.
Background technology
Graft technology is the basic fundamental means of plant species improvement, grafting new varieties, the even sprout of other kinds on veteran or other kind stocks, utilize the root system of stock and trophic system as growing nutrient base, impel shoot to grow fast, reach the object of fast breeding.Not only be conducive to the cycle shortening 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, is abutted against, no matter adopt which kind of grafting method, saw as grafting tool branch the 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 dry, there is no the secretion of moisture and myron, sawing is lighter, lumber fibre is easily blocked by neat, and due to sawtooth be all the staggered abduction in left and right, the sawing seam of self-assembling formation is wider, is greater than the thickness of saw blade, can not produces the phenomenon of pressing from both sides stagnant saw blade.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 not easily truncated, and is mostly to tear disconnected, and the cross section of sawing must be caused irregular, irregular xylem fibre broken end is collected in sawing seam, and that sawing must be caused to stitch is narrow.Meanwhile, myron and moisture cause saw blade surface viscous, and the effect of two aspects causes binding phenomenon, and major injury sawtooth.When dispatching from the factory, the sawtooth abduction part of processing is polished, and sawing process cannot form nature and expand gap effect, and binding phenomenon must be caused more serious, and workman, when operating, can only pull at, careless slightly, namely can fracture by saw blade, but also may injure personnel.For this reason, develop a kind of structure simple, have nature and expand gap function, the special saw of seedling grafting with anti-binding function effectively avoiding binding phenomenon to occur is the effective way addressed this problem.
Summary of the invention
The object of the present invention is to provide a kind of structure of a kind of development simple, the special saw of seedling grafting with anti-binding function effectively avoiding binding phenomenon to occur.
The object of the present invention is achieved 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 in the maximum gauge in sawtooth portion and the sheet body portion of saw blade is 1:0.5 ~ 1, described sawtooth arranges buckling groove, and described saw blade is by buckling groove and expansion gap device snap-fit engagement.
The present invention adopts to arrange on saw blade and expands the mode of gap device, saw blade is possessed expansion gap function.In sawing process, except the expansion gap of sawtooth self-assembling formation, by expanding gap device, sawing gap being widened, amputating xylem fibre broken end simultaneously, avoid myron and the moisture viscous saw blade of secretion, make sawing more smooth, smooth.Structure of the present invention is simple, be easy to implement, one or more expansion gap device can be set as required, when not needing 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 the drawback that prior art branch saws the damage of easy binding, contribute to reducing production cost, improve the safety of workman's grafting operation.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated, but limited the present invention never in any form, and any change done based on training centre of the present invention or improvement, all belong to protection scope of the present invention.
As shown in Fig. 1 ~ 5, the present invention includes 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 in the maximum gauge in sawtooth portion and the sheet body portion of saw blade 1 is 1:0.5 ~ 1, it is characterized in that described sawtooth 11 arranges buckling groove 12, described saw blade 1 at least arranges one and expansion gap device 3.
Described expansion gap device 3 is in " n " shape, and both sides arrange edge 32, and its inside arranges edge clipping 31, by being arranged on saw blade 1 with buckling groove 12 snap-fit engagement is fastening.
The cross section arc top shape structure symmetrically of described expansion gap device 3 liang of edges 32, arranges the edge clipping 31 coordinated with buckling groove 12 between the two.
Fig. 6, Fig. 8 show invention the second embodiment, and the cross section obtuse triangle structure symmetrically of described expansion gap device 3 liang of edges 32, it narrows near sawtooth direction, broadens gradually successively to hump direction, narrows gradually again to 1/2 ~ 2/3 place.AA to sectional view;
Fig. 7, Fig. 8 show the second embodiment of the present invention, and the cross section triangular structure of right angle symmetrically of described expansion gap device 3 liang of edges 32, it narrows near sawtooth direction, broadens gradually successively to hump direction.
Orthographic projection circular arc fusiformis structure symmetrically on described expansion gap device 3 liang of edges 32, the both sides namely along saw blade parallel direction are thinning gradually, thickening gradually to centre, and maximum aggregate thickness is 3:1 ~ 0.5 with the ratio of saw blade thickness.
Orthographic projection equilateral triangle symmetrically on described expansion gap device 3 liang of edges 32, the both sides namely along saw blade parallel direction are thinning gradually, thickening gradually to centre, and maximum aggregate thickness is 3:1 ~ 0.5 with the ratio of saw blade thickness.
Described expansion gap device 3 liang of edges 32 are parallel to saw blade bearing of trend and at least one expansion gap tooth 33 is set.
Expansion gap tooth 33 on described expansion gap device 3 protrudes from edge 32 outer rim, and along saw blade bearing of trend in the circular arc towards saw blade.
The side projection shape of the expansion gap tooth 33 on described expansion gap device 3 is the wide fusiformis structure in narrow centre, two ends, and parallel with jaggies.
operation principle of the present invention and the course of work:
The present invention adopts to arrange on saw blade and expands the mode of gap device, saw blade is possessed expansion gap function.In sawing process, except the expansion gap of sawtooth self-assembling formation, by expanding gap device, sawing gap being widened, amputating xylem fibre broken end simultaneously, avoid myron and the moisture viscous saw blade of secretion, make sawing more smooth, smooth.
Before using, what first whether inspection expansion gap device was firm is installed in the buckling groove of saw blade.Used saw, check whether to need to change and expand gap device.During concrete use, first can not fill expansion gap device, for sawing cut out saw kerf after, be loaded on expansion gap device.Or saw blade leading portion does not fill expansion gap device, only in, back segment installing expands gap device, and sawing can be made so lighter.
After finishing using, the most handy carpenter cleans saw and expansion gap device surface by wash oil, uses in order to next time.
