Description
Technical field
The utility model relates to technical field of garden, especially a kind of to be repaired by what power-actuated reciprocating swing was cut
Secateurs knife.
Background technique
The shrub and hedge trimmer of current driving force driving are repaired because it has many advantages, such as high-efficient, easy to use in plant protection, gardening
Cut, the fields such as municipal gardens nursing are more and more applied, power shrub and hedge trimmer are staggeredly moved back and forth by blade, are come real
Referring now to the shearing work of hedge, branches and leaves etc..The shrub and hedge trimmer of the power drive reciprocating cutting of currently known technology are generally by upper and lower
Two blades form, and have several cutter heads on each blade, have two cutting edges on each cutter head, two blades do phase
Pair straight reciprocating motion, be achieved in the cutting to plant, and at present the power shrub and hedge trimmer of this structure there are two types of than
More typical blade type, a kind of blade be it is only unilateral there is cutter head, as shown in fig. 6, another kind is then bilateral all to have
Cutter head, as shown in Figure 7.The power shrub and hedge trimmer of above structure have the characteristics that structure is simple, cutting power is strong, but also deposit
Extruding will form to plants shoots, tear in some shortcomings, such as linear reciprocation cutting, cause tearing rate higher, be easy to hedge
Basketry, trees cause to damage.In view of the above-mentioned problems, many manufacturers and research institution are developed and have been developed, but so far still
There is not comparatively ideal product to emerge.
Summary of the invention
To overcome drawbacks described above of the existing technology, the purpose of the utility model is to provide it is a kind of it is simple and reasonable,
Easy for operation, shear velocity damages the pruner of the reciprocating swing cutting small, work efficiency is high fastly, to branch.
The utility model solves technical solution used by above-mentioned technical problem, it includes ledger-plate, cutting blade, driving company
Several stationary knife heads are distributed on the ledger-plate for bar, and stationary knife head has cutter head shear surface, wherein stationary knife head only has single side end to end
Cutter head cutting edge, each stationary knife head between stationary knife head has two-sided cutter head cutting edge end to end, has phase between adjacent stationary knife head
With cutter head spacing and constitute the V-arrangement edge of a knife；Cutting blade correspondence is distributed between two adjacent stationary knife heads, and cutting blade is sheared with blade
The middle part of face and double-edged razor blade cutting edge, cutting blade is hinged on ledger-plate by pin shaft correspondence, and cutter head shear surface is cut with blade
Section is bonded to each other, the V-arrangement edge of a knife group V shaped scissors in pairs between double-edged razor blade cutting edge and adjacent stationary knife head on cutting blade
Mouthful, the tail end of all cutting blades is by pin-hinges in drive link.
The angle that is swung left and right of the further scheme of the utility model, the cutting blade is the angle α, and the angle α is controlled in 30-60 degree
Between.
The further scheme of the utility model, the drive link and ledger-plate are arranged in parallel, the knife of each cutting blade
Head motion amplitude matches with cutter head spacing, and when driving mechanism drives drive link to move reciprocatingly, each cutting blade is in V-arrangement
Reciprocating swing moves in the edge of a knife.After adopting the above structure, it has the following advantages compared with prior art and effect: since ledger-plate is solid
Fixed motionless, when power drive unit drives drive link linear reciprocating motion, drive rod is imparted power to dynamic by pin
Blade, cutting blade will fix the reciprocating swing rotation of angle around pin shaft, to make cutting edge of blade on cutting blade and fixed
Shear action is formed between cutter head cutting edge on cutter head；This shear action is similar to the shearing that manual scissors one opens a conjunction,
But have on shearing frequency, strength and shearing work width and be obviously improved, such shear action it is possible to prevente effectively from
It to the extruding of plants shoots and is torn when cutting branches and leaves, hence it is evident that reduce tearing rate, protect hedge and branch.

Wherein 1 ledger-plate, 2 stationary knife heads, 3 cutter head shear surfaces, 4 cutter head spacing, 5 cutting blades, 6 cutting edge of blade, 7 drivings connect
Bar, 8 pins, 9 pin shafts, 10 cutter head cutting edges, 11 blade shear surfaces, the 12V shape edge of a knife, 13V shape scissors mouth.
Specific embodiment
Shown in Fig. 1 to Fig. 5, for the specific embodiment of the pruner of the utility model reciprocating swing cutting, it includes
Several stationary knife heads 2 are distributed on the ledger-plate 1 in ledger-plate 1, cutting blade 5, drive link 7, and stationary knife head 2 is cut with cutter head
Section 3, wherein stationary knife head 2 only has single side cutter head cutting edge 10 end to end, each stationary knife head 2 between stationary knife head 2 has double end to end
