A kind of adjustable gardens pruning cutter
Technical field
This utility model relates to garden craft equipment technical field, is specifically related to a kind of adjustable gardens pruning cutter.
Background technology
nullGeneral in order to increase the appreciative value of ornamental plant,The trees of Chinese garden planting,Need periodically branch、Trunk is pruned,Gardens use artificial shears to prune for the pruning of branch mostly at present,But this shears is owing to being limited by its decreased food,Remote and the highest plant cannot be carried out cutting,This artificial shears is easier when cutting is near the branch on earth's surface,But for the local branch higher away from ground,Need to operate by ladder or other garden instruments,Operation easier is made to be greatly increased undoubtedly,And the fulcrum of power is not had in the air at height,Operate extremely difficult,Cause work efficiency low,In addition,Also certain danger is had in work high above the ground,Imprudence is possible to fall from the ladder,So for the selection of staff also it is necessary to have certain condition,This can increase the cost of work,And it is the most obvious for safeguarding the effect of garden craft trees.
At present for some special landscape plants, it is necessary to use artificial way to carry out cutting, but at present building of using of gardener cutter is the most old-fashioned, structure is outmoded builds cutter, the use demand of gardener at present far away.
Summary of the invention
For problem above, this utility model provides a kind of adjustable gardens pruning cutter, by expansion link and interior bar are combined, and the individually operated control of handle on both sides, two handles making pruning shear can arbitrarily regulate its length, cutter hub is designed as arc can reduce the frictional resistance of shears, more preferably, each several part end of the branch more accurately it is trimmed to, it is also prevented from because pruning " the mistake pruning " caused for a long time, simple to operate and safety, job costs are substantially reduced, and work efficiency can be greatly improved, and can effectively solve the problem in background technology.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of adjustable gardens pruning cutter, including upper shear blade, lower scissors sheet, shear shank and rivet, described upper shear blade and lower scissors sheet by rivet be superimposed with each other together with form integral structure, described shear shank connects shear blade and lower scissors sheet respectively, also include back-up wrench and corner, described fixed wrench is located on rivet, described upper shear blade and lower scissors sheet are connected to telescopic shaft and lower telescopic shaft, described upper telescopic shaft and lower telescopic shaft connect shear shank, interior expansion link it is provided with in described shear shank, described interior expansion link is connected with interior bar by upper Telescopic spanner and lower flexible wrench, described interior bar connects with handles.
Further, described upper telescopic shaft and lower telescopic shaft end connect corner.
Further, described cutter hub shape-designing is circular arc or half elliptic.
Further, described handle is provided with rubber cover, and described rubber cover is carved with rough sulculus.
The beneficial effects of the utility model:
This utility model is by combining expansion link and interior bar, and the individually operated control of handle on both sides, two handles making pruning shear can arbitrarily regulate its length, cutter hub is designed as arc can reduce shears and arbor, frictional resistance between flowering shrub, for branch, for the plant that dry density is bigger, in order to more preferably, more accurately it is trimmed to each several part end of the branch, such as parallel branch, intersection branch, it is also prevented from because pruning " the mistake pruning " caused for a long time, simple in construction, novel in design, rationally, production Technology requires the highest, less due to the strength needed at ground construction, so typically can work continuously the longer time, this instrument operates for women and children and is also easy to, simple to operate and safety, job costs are substantially reduced, work efficiency can be greatly improved.
Accompanying drawing explanation
Fig. 1 is this utility model overall structure schematic diagram.
Figure is numbered: the upper shear blade of 1-, 2-lower scissors sheet, 3-rivet, 4-back-up wrench, telescopic shaft under 5-, the upper telescopic shaft of 6-, 7-corner, 8-shear shank, expansion link in 9-, Telescopic spanner under 10-, the upper Telescopic spanner of 11-, bar in 12-, 13-handle, 14-rubber cover.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1, a kind of adjustable gardens pruning cutter, including upper shear blade 1, lower scissors sheet 2, shear shank 8 and rivet 3, described upper shear blade 1 and lower scissors sheet 2 by rivet 3 riveting be superimposed with each other together with form integral structure, described shear shank 8 connects shear blade 1 and lower scissors sheet 2 respectively, also include back-up wrench 4 and corner 7, described fixed wrench 4 is located on rivet 3, described upper shear blade 1 and lower scissors sheet 2 are connected to telescopic shaft 6 and lower telescopic shaft 5, described upper telescopic shaft 6 and lower telescopic shaft 5 connect shear shank 8, interior expansion link 9 it is provided with in described shear shank 8, described interior expansion link 9 is connected with interior bar 12 by upper Telescopic spanner 11 and lower flexible wrench 10, described interior bar 12 connects with handles 13.
On above-described embodiment preferably, described upper telescopic shaft 6 and lower telescopic shaft 5 end connect corner 7.
On above-described embodiment preferably, described upper shear blade 1 and lower scissors sheet 2 shape-designing are circular arc or half elliptic.
On above-described embodiment preferably, described handle 13 is provided with rubber cover 14, and described rubber cover 14 is carved with rough sulculus.
Based on above-mentioned, this utility model is by combining expansion link and interior bar, and the individually operated control of handle on both sides, two handles making pruning shear can arbitrarily regulate its length, cutter hub is designed as arc can reduce shears and arbor, frictional resistance between flowering shrub, for branch, for the plant that dry density is bigger, in order to more preferably, more accurately it is trimmed to each several part end of the branch, such as parallel branch, intersection branch, it is also prevented from because pruning " the mistake pruning " caused for a long time, simple in construction, novel in design, rationally, production Technology requires the highest, less due to the strength needed at ground construction, so typically can work continuously the longer time, this instrument operates for women and children and is also easy to, simple to operate and safety, job costs are substantially reduced, work efficiency can be greatly improved.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
