Description
Technical field
The utility model is related to a kind of modified averruncator, espespecially a kind of averruncator with good shear effect.
Background technology
Averruncator is the instrument that everybody daily pollard is commonly used, and is largely withe spray during trimming, than
Trimming is easier to, but relatively thick harder branch also occurs once in a while, conventional method is one saw of extra installation on averruncator
Bar, in case of need, but so, causes cost to raise for a moment, and two can also make the complexity that the structure of averruncator becomes, when being not required to
When cutting thick branch, saw blade can hinder the work of averruncator, or need to disassemble, and process is cumbersome.
Therefore, it is necessary to a kind of modified averruncator be designed, to overcome above mentioned problem.
Utility model content
For background technology problem encountered, the purpose of this utility model is the modified branches of tall trees for providing a kind of improvement
Cut, it is not necessary to which saw blade is installed, also being capable of preferable pollard.
To realize the effect above, the utility model uses following technological means：A kind of modified averruncator, including it is flexible
Bar, cutting assemblies and strengthened rope, the cutting assemblies include fixed blade and active blade, the fixed blade and the institute being hinged
State and sawtooth is provided with active blade, the fixed blade is connected by the upper end of fixed handle and expansion link, on the fixed handle also
It is provided with a support, the support and is provided with lower sheave, top sheave, the strengthened rope is provided with the rear portion of the active blade
One end successively bypass the top sheave and the lower sheave, and be fixed on the rear portion of the active blade, the strengthened rope it is another
One ends wound is in the hand gear being fixed on the expansion link.
Further, it is provided with back-moving spring between the fixed handle and the active blade rear portion.
Further, the back-moving spring is torsionspring.
Further, the active blade is in outer convex, and the fixed blade is engaged with the active blade and bending is in the same direction
Arcs of recesses.
Further, the head of the fixed blade is provided with hook.
Further, the sawtooth is located at the active blade and the fixed blade hinged place.
Further, the serrate part that sets of the active blade is in arcs of recesses.
Compared with prior art, the beneficial effects of the utility model are：Can be with by the sawtooth in fixed blade and active blade
Very thick branch is easily cut, and saw blade, and general branch are installed without extra, is dialled by top sheave, lower sheave and hand
Wheel can also easily be cut, and be used more laborsaving more convenient；, can be by and the head of the fixed blade is provided with hook
The branch of eminence is hung, convenient shearing, is slid while being also possible to prevent branch from cutting assemblies.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Drawing reference numeral is described in detail：
Expansion link 1；Cutting assemblies 2；Fixed blade 21；Fixed handle 211；Support 212；Hook 213；Active blade 22；Reset bullet
Spring 3；Lower sheave 41, top sheave 42；Hand gear 5, rocking handle 51；Strengthened rope 6.
Embodiment
For ease of being better understood from the purpose of this utility model, structure, feature and effect etc., in conjunction with accompanying drawing and specifically
The utility model is described in further detail for embodiment.
Such as Fig. 1, a kind of modified averruncator, including expansion link 1, cutting assemblies 2 and strengthened rope 6, the hand of expansion link 1
Hold part and be provided with hand gear 5, the strengthened rope 6 is stored to wind.
The cutting assemblies 2 include the fixed blade 21 that is hinged and active blade 22, and the active blade 22 can be to be hinged
Rotated centered on point；The active blade 22 is in outer convex, and the fixed blade 21 is engaged and curved in the same direction with the active blade 22
Song is in arcs of recesses, can reduce the torque of branch stress between active blade 22 and fixed blade 21 as far as possible, save strength；Described
The head of fixed blade 21 is provided with hook 2123, can hang the branch of eminence, convenient shearing, while being also possible to prevent tree
Branch slides from cutting assemblies 2.
The fixed blade 21 is connected by fixed handle 211 with the upper end of expansion link 1, is additionally provided with the fixed handle 211
It is provided with one support 212, the support 212 on lower sheave 41, the rear portion of the active blade 22 and is provided with top sheave 42, it is described
One end of strengthened rope 6 successively bypasses the top sheave 42 and the lower sheave 41, and is fixed on the rear portion of the active blade 22, institute
The other end for stating strengthened rope 6 is wrapped on the hand gear 5 being fixed on the expansion link 1, the hand gear 5 and is provided with a rocking handle
51, the rocking handle 51 is rotated, drives the strengthened rope 6 to tighten up, is passing through the top sheave 42 and the lower sheave 41, Ke Yishi
Now only with former 1/3 strength with regard to identical effect can be reached.Although pulling strength can be made by top sheave 42 and lower sheave 41
The distance of rope 6 is elongated, but is due to that take-up goes out to employ hand gear 5, so can't feel inconvenient when use；In addition
Rocking handle 51 above hand gear 5 is on the periphery ring of hand gear 5, can further be saved strength, can so be made minimum
Power shears thicker branch.
Sawtooth is provided with the fixed blade 21 and the active blade 22, the sawtooth is close to the active blade 22 and institute
State the hinged place of fixed blade 21.When there is the harder branch of more heavy manual labour, branch can be put into sawtooth, by rotating expansion link 1
Cutting assemblies 2 are driven to rotate, so as to reach the effect of similar saw.And the serrate part that sets of the active blade 22 is in recessed
Arc, branch is not easily moveable wherein, and the effect of sawing is more preferable.
Back-moving spring 3 is provided between fixed handle 211 and the active blade 22 rear portion, so that having sheared every time
After branch, the fixed blade 21 and the active blade 22 can be separated automatically, convenient to shear next time.In the present embodiment,
The back-moving spring 3 is torsionspring, can avoid the problem on deformation of compression spring.
In summary, can by the sawtooth in fixed blade and active blade by means of above-mentioned technical proposal of the present utility model
Easily to cut very thick branch, and saw blade, and general branch are installed without extra, pass through top sheave, lower sheave and hand
Thumb wheel can also easily be cut, and be used more laborsaving more convenient；, can be with and the head of the fixed blade is provided with hook
The branch of eminence is hung, convenient shearing slides while being also possible to prevent branch from cutting assemblies；The torsionspring
Use, make averruncator be not easy to be damaged, the life-span is more longlasting.
Embodiment described above only expresses a kind of embodiment of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that for the common of this area
