Abstract
The utility model relates to a garden pruning device and provides a branch pruning cutter which comprises a telescopic rod. The upper end of the telescopic rod is connected with a crescent-shaped cutter. The outer side of the cutter is provided with a blade, the inner side of the cutter is provided with saw-teeth, and the tail end of the cutter is provided with a hook. The inner side of the hook is provided with a blade. The branch pruning cutter is characterized in that each section of the telescopic rod is provided with a fixing ring in a sleeved mode, the outer circle of the fixing ring of each section is perpendicularly provided with a transverse connecting rod, the tail end of each connecting rod is connected with a round ring, the connecting rods are connected to the inner sides of the round rings, and the outer sides of the two round ring bodies, vertically connected, of each round ring are vertically connected with telescopic connecting rods. The branch pruning cutter has the advantages that the outer side of the telescopic rod is provided with the outer layer formed by the telescopic connecting rods, the overall telescopic effect is not influenced, the telescopic stability can be improved, the structural strength of the middle section is improved, the telescopic rod is protected to the greatest extent and can not be broken easily, and the service life is prolonged.
Description
Technical field:
The utility model relates to a kind of gardens pruning instrument, is specifically related to a kind of horticultural branching cutter.
Background technology:
In the greening in gardens, maintenance personnel often need to carry out pruning shaping to afforestation, for some short and small shrubs, can prune by pruning knife, but for some tall and big arbors, what branch line was thin can prune with averruncator, and thicker just need to or the climing up a tree by ladder of branch pruned with chopper or saw, maintenance personal security is threatened, the accident that easily meets accident, and need to be with the instruments such as ladder, chopper, saw, dangerous and trouble when operation.For head it off, be badly in need of prior art to improve.
Open (bulletin) number: CN203167645U, utility model title: a kind of horticultural branching instrument, for addressing this problem, provide a kind of pruning shear, utilize expansion link and tulwar to cut branch, can make maintenance personnel in the face of high arbor is pruned with standing in, but because the flexible rear length of expansion link is longer, brandish expansion link, tulwar is cut arbor branch, and two active forces are concluded the business mutually and made expansion link fracture.
Utility model content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, provides and can protect expansion link, the pruning knife increasing the service life.
Above-mentioned technical problem of the present utility model, is mainly solved by following technical proposals:
A kind of pruning knife, comprise expansion link, expansion link upper end is connected with crescent cutter, and its outside is blade, inner side is with sawtooth, end is crotch, and the inner side of crotch is blade, it is characterized in that: on every section of bar of described expansion link, cover has retainer ring, retainer ring outer ring one circle on every section of described bar is vertically provided with connecting rod, connecting rod end connects annulus, and connecting rod is connected to annulus inner side, and two annulus outsides that described annulus is connected up and down are vertically connected with shrinking connecting-rod.
Described retainer ring second pole from expansion link end starts to arrange.
Described two annulus outsides that are connected up and down are vertically connected with three shrinking connecting-rods.
Three described shrinking connecting-rods are between two 120 ° and are distributed in annulus outside.
The beneficial effects of the utility model are: in expansion link outside, set up the skin forming with shrinking connecting-rod; make not affect integral telescopic effect; can also be that flexible stability is enhanced; and strengthened the structural strength in stage casing; make expansion link obtain maximum protection; easy fracture, does not increase the service life.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation;
Wherein: 1: expansion link; 2: blade; 3: sawtooth; 4: crotch; 5: retainer ring; 6: connecting rod; 7: annulus; 8: shrinking connecting-rod.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of pruning knife, comprise expansion link 1, expansion link 1 upper end is provided with and is connected with crescent cutter, its outside is blade 2, inner side is with sawtooth 3, end is crotch 4, the inner side of crotch 4 is blade 2, wherein on every section of bar of expansion link 1, cover has retainer ring 5, retainer ring 5 second pole from expansion link 1 end starts to arrange, wherein 5 outer ring one circles of the retainer ring on every section of bar are vertically provided with connecting rod 6, connecting rod 6 ends connect annulus 7, connecting rod 6 is connected to annulus 7 inner sides, two annulus 7 outsides that are wherein connected up and down are vertically connected with three shrinking connecting-rods 8, three shrinking connecting-rods 8 are between two 120 ° and are distributed in annulus 7 outsides.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
