Description
Technical field
The utility model relates to a kind of labor-saving gardening scissors, refers to a kind of reaction force average mark can being shed especially, and can limit the labor-saving gardening scissors of the maximum stretching degree of tool ends end.
Background technology
Home environment or company, in the park in order to beautify the environment, increase greenery, how can plant many flowers and shrubs or even large-scale tree, to improve the atmosphere in whole living environment space, and flowers and shrubs is along with implantation time, branches and leaves can arbitrarily be grown and scatter and, at this moment must do in good time pruning, attractive in appearance to increase it, drop to pound with the branch that prevents to wear out and hurt sb.'s feelings, yet partly branch is thick and stiff, be not easy to prune, must utilize the capable pruning work of waylaying and rob of the gardening of the laborsaving effect of tool, easily thick and stiff branch being cut off again fast, and how as shown in Figure 8 at present common orchard shears structure, it has a metallic plate 60, one first elongated elements 70 and one second elongated elements 80, wherein metallic plate 60 is provided with one first pivoting point 61, one blade 62 and that extends forward extends back and has the tang 63 of one second pivoting point 64, this second pivoting point 64 also separate a distance of being scheduled at interval with first pivoting point 61, first elongated elements 70 is to pivot on first pivoting point 61, and be connected on the metallic plate 60, this first elongated elements 70 also has forward an extension jaw 71, and can with blade 62 consistent starts, with will be contained in these extension jaw 71 formed bends be sheared thing such as branch cuts off, first elongated elements 70 is also to have the arm 72 that extends back again, and first sector gear 73 that is positioned at this extension jaw 71 and adjutage 72 middle parts, second elongated elements 80 has the portion 81 that extends back, and second a relative sector gear 82, this second elongated elements 80 is to pivot on second pivoting point 64, and be connected on this metallic plate 60, make first, two sector gears 73,82 can be meshing with each other, to produce the relation of interlock.
So, aforesaid known structure still has following problem points in practical application: (one) its first elongated elements 70 and second elongated elements 80 be only monolateral to be arranged on the outside of metallic plate 60, so when the application of force is sheared and produced when reaction force is arranged, this reaction force will be concentrated in the place that is meshed of first elongated elements 70 with second elongated elements 80 of this monolateral setting, and can't shed from bilateral average being divided, make this shear action be subjected to monolateral stressed concentrated influence easily, and produce the phenomenon that start has some setbacks; (2) 80 of its first elongated elements 70 and second elongated elements pivot group only, and can't be mutual spacing, so work as the application of force with first, two elongated elements 70,80 past opposite directions are done when pivoting, will be because of first, two elongated elements 70,80 not restrictions mutually mutually, and make first, two elongated elements 70,80 quite easily because the application of force is just opened accidentally to maximum for the moment, this to maximum orchard shears not only be helpless to promote the maximum size sheared (because blade 62 need be sheared thing and keep a suitable shearing inclination to cut smoothly, if branch is excessive, cause blade 62 and be sheared between thing the angle that forms near vertical, will make shear action finish smoothly, maybe need expend great strength could shear smoothly), more can be because of first, two elongated elements 70,80 excessively open, and when closing, need the long distance that pivots relatively, this in the use will be more consuming time, consumption power, and inconvenience.
Being with, the utility model people promptly in view of this, is to think and the idea of creation, satisfies with for many years experience and is designed, and through inquiring into and study sampling test in many ways, and repeatedly revises improvement, is to release the utility model.
The utility model content
The technical problem point that desire solves:
Known laborsaving shear structure, it is only monolateral stressed, and can't limit first and second elongated elements and excessively open, and this is the technical problem point that desire solves.
The technical characterstic of dealing with problems:
Labor-saving gardening scissors of the present utility model, it is by an operator body, one secondary cutter hub, one cushion block, one double-action plate and two involutory force arms cooperate some screws, nut lock knot forms, wherein, the inclined to one side side in operator body below is extended a handle-holding rod, the stage casing middle position is provided with a main pivot hole, opposite side then is provided with an eccentric pivot hole partially in below, main pivot hole, be provided with a tool ends end in the top combination of operator body in addition, this tool ends end is to can be cutter anvil or blade, secondary cutter hub stage casing is provided with a main pivot hole, the inclined to one side side of hypomere is provided with the extension of a strip, terminal and the past opposite side bending in extension, and be formed with an interlock tooth bar, interlock tooth bar top then forms the portion of dodging of a permeable type being aligned with the zone of containing the extension, below, main again pivot hole is the limit guide groove that is provided with an arc shape at the opposite position with the extension and the portion of dodging, secondary cutter hub epimere then is formed with a tool ends end, and this tool ends end is to can be cutter anvil or blade, cushion block is provided with two combined holes, the double-action plate below is provided with the interlock tip edge of an arcuation, the inclined to one side side in interlock tip edge top is provided with a protuberance, on the protuberance and be provided with two combined holes, force arm is that bending is the ㄣ shape, its hypomere is provided with handle-holding rod, the inclined to one side side of epimere also is provided with eccentric pivot hole, and eccentric pivot hole bottom center then is provided with two combined holes; Thus, be to constitute this labor-saving gardening scissors.
Wherein, two tool ends end are established the kenel that is a chopping block, a blade.
Wherein, two tool ends end are established and are the tangent kenel of two blades.
The effect of contrast prior art:
(1) labor-saving gardening scissors of the present utility model, its secondary cutter hub is pulled betwixt by the two force arm folders that are involutory, when the application of force is sheared and produced when reaction force is arranged, can make this reaction force be shed by average force arm branch from being installed in secondary cutter hub both sides, so do not have force localization relatively on monolateral, the situation that causes shear action to have some setbacks.
(2) labor-saving gardening scissors of the present utility model, because screw is when the limit guide groove intrinsic displacement, it is at utmost open to be used for limiting tool ends end, so in use, unexpected relatively have tool ends end excessively to open, and when closing, need long distance consuming time, consumption power to pivot, this will be more convenient in the use, simultaneously because the scope that limit guide groove is contained has been the full-size that this orchard shears can be sheared, so when shearing use, there also do not have tool ends end to open to be too small, causes the not good problem of applicability.
