Description
Technical field
A kind of tree branch pruning tool is the utility model is related to, more specifically, it relates to a kind of averruncator.
Background technology
Trees averruncator is a kind of gardening pruning picker, is exactly branch or fruit to trees eminence as its name suggests
A kind of instrument trimmed or plucked, it is one of indispensable instrument of trees attendant.
At present, notification number is that CN104272985A Chinese patent discloses a kind of averruncator, and it includes expansion link, sets
Knife rest at the top of expansion link, the rotating knife being rotatably connected on knife rest being connected, for drawing by rotational structure with rotating knife
The drawstring that turn moving knife rotates；Knife rest is further fixed on cutting knife, and the blade side of cutting knife is provided with sawtooth.
This high branch shears structure is simple, is by branch by the sawtooth on cutting knife when to more thick branch pruning
It is sawed-off, but averruncator is often heavier, worker holds averruncator and moved up and down more arduously, and production efficiency is relatively low.
Utility model content
In view of the deficienciess of the prior art, the utility model is to provide a kind of averruncator, can be easy to saw in branch
It is disconnected, reach the purpose of improving production efficiency.
To achieve the above object, the utility model provides following technical scheme：A kind of averruncator, including support bar, institute
The first scissor body is fixed with the support bar stated, the second scissor body is hinged with the first described scissor body, described second cuts
Drawstring is connected with cutter hub, connecting rod is rotatably connected on described support bar, saw blade is fixed with described connecting rod, it is described
Connecting rod on be fixed with the first drive, be rotatably connected to the second drive on described support bar, the described first transmission
Wheel is connected by transmission belt with second drive, and drive rod is fixed with the second described drive.
By using above-mentioned technical proposal, when needing sawed-off branch, a holds support bar, another holds are driven
Lever, saw blade, which is placed on, to be needed on sawed-off branch, rotation driving bar, makes drive rod drive the second rotating wheel to rotate, and second
Rotating wheel drives the first drive to rotate by transmission belt, the first drive is driven saw blade rotation, passes through cutting for saw blade
The effect of cutting, branch is cut off, and whole process eliminates the complicated processes that worker moves up and down support bar, so as to make worker cut off tree
More laborsaving, the improving production efficiency of branch.
The utility model is further arranged to：Described saw blade includes support plate, elastic component and for cutting scraping for branch
Knife, described support plate are fixed in the connecting rod, and radial direction of the described scraper along support plate is slided with the support plate to be connected
Connect, the both ends of described elastic component are fixedly connected with the support plate, scraper respectively.
By using above-mentioned technical proposal, during connecting rod is rotated, connecting rod is driven support disc spins, pass through
The effect of centrifugal force, scraper is moved toward the direction away from support plate, and contacted with branch, then cut off branch, and pass through
The pulling force effect of spring, it is not easy to make scraper separate with support plate；When saw blade need not be used, made by the elastic force of elastic component
With scraper is retracted in support plate, is not easy scratch worker, improves the protective effect to worker.
The utility model is further arranged to：The external diameter of the second described drive is more than the external diameter of the first drive.
By using above-mentioned technical proposal, the second drive is rotated into a circle so that the first drive can rotate multi-turn,
It is easy to cut branch, effective improving production efficiency.
The utility model is further arranged to：Striker plate is fixed with the outer wall of described support plate.
By using above-mentioned technical proposal, during branch is cut, caused chip is most of by striker plate
Block, so as to be not easy to drop into the eye of worker, improve the protective effect to worker.
The utility model is further arranged to：The one end of described support bar away from the first scissor body slidably connects positioning
Bolt, positioning hole is offered on described drive rod, described pilot pin is arranged in the positioning hole.
By using above-mentioned technical proposal, by the way that pilot pin is arranged in positioning hole, by the outer wall of pilot pin and positioning
The inwall in hole contradicts, you can positions drive rod, makes drive rod be not susceptible to rotate, so that scraper is not easy scratch worker, carries
Protective effect is risen.
The utility model is further arranged to：The one end of described support bar away from the first scissor body slidably connects extension
Cover, locking member is threaded with the outer wall of described extension set, the outer wall conflict of described locking member and the support bar is set
Put.
By using above-mentioned technical proposal, support bar is moved toward the direction away from extension set, then locking member is rotated, will
The outer wall of locking member and support bar contradicts, and produces larger frictional force, is easy to cut higher branch, and lifting is practical
Property.
The utility model is further arranged to：The one end of described extension set away from support bar is fixed with support set, described
The one end of support set away from the extension set offer placement groove.
By using above-mentioned technical proposal, the setting of groove is placed, the contact area with worker can be lifted so that worker
It is more comfortable when using this averruncator.
The utility model is further arranged to：Antiskid groove is offered on the outer wall of described support bar.
By using above-mentioned technical proposal, worker can be easy to adjust the position of support bar, no with holds antiskid groove
Easily make the sweat that hand flows out and make worker be difficult to hold support bar.
In summary, the utility model has the advantages that：
Contradicted by the shoulder that placement groove is placed in worker, a hand grips antiskid groove, and another hand rotates driving
Bar, the second drive is driven to rotate by drive rod, the second drive drives the first drive to rotate by transmission belt, makes first
Drive drives connecting rod to rotate, and connecting rod drives support plate to rotate, by the effect of centrifugal force, by scraper toward away from support plate
Direction it is mobile and contradicted with branch, branch is cut sawed-off.
