Description
Technical field
The utility model relates to hand-held tool field, specifically a kind of averruncator.
Background technique
Secateurs carries out wiping out operation as gardens gardening pruning tool mainly for little tree high-altitude branch.In practical operation
In the process, since some trees are higher, traditional secateurs can not achieve the trimming to high-altitude branch, although the body of rod of some secateurs
It is able to carry out adjusting, but since shear body is on top, it is not easy to operate.
With the raising of technical level, more and more tools for high-altitude trimming come out.In actual use,
There are many deficiencies.
As Chinese patent " averruncator (ZL201620972239X) " discloses that one kind realizes height by gear engaged transmission
The tool of secateurs work is held, in use, by gear set transmission force, structure is complicated for this averruncator, in painstaking beta pruning
During be easy to appear it is de- cut, slip teeth phenomena such as, not only influence working efficiency, but also maintenance rate is high, influences job schedule.
As Chinese patent " averruncator (201630513854X) " discloses a kind of high-end secateurs work by link transmission
Tool, the patent are appearance patent, have its disclosed attached drawing it will be evident that its shear body and hand part are connect by connecting rod,
In use process, what connecting rod transmitted is the power of up and down direction, and the angle of shear body cannot change, and the branch for being not easy to different location carries out
Trimming.
It is that set several pulley blocks in shear body back laborsaving to realize, although reaching in this way in addition, there are also some averruncators
Shearing force, but complicated pulley block mechanism is not easy to shuttle in irregular branch clump, and back segment gear drive resistance is also big, after shearing
The playback of snip is often not in place, and working efficiency is extremely low.
In conclusion currently used for the tool of high-altitude trimming, there are many defects, cannot serve high-altitude trimming well,
This is those skilled in the art's urgent problem.
