A kind of Multifunctional secateurs
The utility model relates to a kind of Multifunctional secateurs, belongs to gardens, gardening specific purpose tool technical field.
The instrument that pruner is a kind of gardens, horticultural field is conventional, the pruner function singleness used at present, can not be used for cutting cutting scion, and grafting cut get scion time, technology is not easily grasped, and operation easier is large, wastes time and energy; Will be used alternatingly the instruments such as grafting knife, chopper, hammer during grafting, bothersome time-consuming, efficiency is low, and what is more important easily hurts the hand of operator, dangerous.
Utility model content
The purpose of this utility model is to provide a kind of Multifunctional secateurs, can not only beta pruning, and the instruments such as grafting knife, chopper, hammer can be replaced to complete grafting; Processing ease, need not practise just cutting fast cutting scion, just can complete grafting, save trouble time saving and energy saving, raise the efficiency without other instruments, ensures safety, not easily hurts the hand of operator, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: a kind of Multifunctional secateurs, comprises large snip, little snip, bearing pin, torsion spring, grab, and the leading portion of little snip has 10mm to be straight, has one to exceed shear surface 1.5mm denation at medial surface.
Said denation is long 10mm in little snip top inner side plane, and top is near knife edge 1mm, and lower end is near knife edge 2mm, and longitudinal denation of high 1.5mm, nearly knife edge face is vertical, and knife edge face far away is inclined-plane.
Good effect of the present utility model is: the utility model not only can beta pruning, and the instruments such as grafting knife, chopper, hammer can be replaced to complete grafting.Utilize lever principle laborsaving when cutting and cutting scion; It is certain that movement locus when cutting cut by large snip, ensures that scion bevel is straight, reduce technical difficulty, save time; Distance because of denation and little snip cutting edge is outer little greatly inner, makes scion two bevel cut laterally outer thin inner thick, makes scion form layer and forms layer with stock and be combined more closely, more easily survive, scion also can be avoided outwards to slide; The overall process that during grafting, the utility model can complete scion clip, cut, cuts stock, splits stock, no longer with being used alternatingly the instruments such as grafting knife, chopper, hammer, saving trouble saves time; The finger of operator away from cutting edge, can ensure safety.Grafting speed 60% can be improved, improve survival rate, reduce technical difficulty, save trouble time saving and energy saving, more importantly ensure safety, not easily hurt the hand of operator; Have make simple, with low cost, easy to use, one cut the features such as multiplex.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment schematic diagram;
Accompanying drawing 2 is the little snip schematic side view of the utility model embodiment;
Accompanying drawing 3 is the utility model embodiment little snip top schematic top plan view;
In figure: little snip top 1, denation 2, little snip 3, large snip 4, bearing pin 5, torsion spring 6, grab 7.
Below in conjunction with accompanying drawing, by embodiment, the utility model is described further.
In an embodiment, a kind of Multifunctional secateurs, little snip top 1, denation 2, little snip 3, large snip 4, bearing pin 5, torsion spring 6, grab 7.In figure, little snip 3 and large snip 4 are hinged and can relatively rotate by bearing pin 5, and torsion spring 6 two ends are inserted into cuts in the recess of handle, is provided with longitudinal denation 2 inside little snip top 1.
Using method of the present utility model: the utility model is when grafting, and the general right hand is held the utility model Multifunctional secateurs and first cut a section stock; Then interposition fringe base portion is cut, allow scissors open as far as possible, left hand holds scion, make scion base portion bottom surface be a bit larger tham 1/2 place and prop up little snip top 1, scion is allowed to lean against on the downside of large snip top apart from 40-50mm place, bottom surface, hold with a firm grip and cut handle and cut and cut scion, then nearly for scion axial-rotation 180 degree, scion bottom surface is allowed to prop up little snip top 1, scion base portion bevel is near inside denation 2, and length (one is long and the other is short for isometric, the cut-grafting of cleft grafting two bevel and side grafting two bevel) makes scion lean against to cut on the downside of large snip top to cut scion as requested; Finally use scissors slitting stock, pry open stock clip with large snip, stock is inserted outwardly in slightly thick for scion side, form layer alignment, stay white above, clutch wrapping.
