Abstract
The invention discloses a pruning tool. A to-be-sawed trunk is clamped by two saw blades under the action of a spring, the handle is continuously rotated, and then the trunk can be sawed by sawteeth. The pruning tool has the advantages that under the action of the spring, the easiness in movement of the saw blades is avoided during work, the accuracy of sawing position is guaranteed, the pressure on the trunk is always maintained by the sawteeth at the two sides through the spring, the operation stability can be always maintained, and the working efficiency is improved; the handle is longer, so an operator can stand on the ground and continuously rotates the handle to enable the sawteeth to continuously saw the trunk, a climbing tool is not needed, the operation is convenient, and the cost is reduced.
Description
Technical field
The present invention relates to gardens operating equipment technical field, particularly relate to a kind of beta pruning instrument.
Background technology
Beta pruning is that tree branches will consume a lot of nutrient too much, and unnecessary branch is cut, and will reduce consumption, is conducive to little tree and grows tall in order to control tree body branch quantity.In addition, some ornamental trees and shrubs will be pruned, just more good-looking.In beta pruning process, thinner branch can be cut by direct scissors, thicker limb is then needed to use saw blade to amputate.
In prior art, prune picker uses common saw blade, but due to limb higher, need the instrument such as to scale a ladder to carry out work, inconvenient operation; The sawtooth of common saw is linear in addition, less with limb contact point, and easily slide and depart from, need constantly to correct, operating efficiency is lower.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of beta pruning instrument, accurate positioning, easy to operate, save cost.
A kind of beta pruning instrument that the present invention proposes, comprising: the first arc saw blade, sawtooth is positioned at inner arc side; Second arc saw blade, sawtooth is positioned at inner arc side, corresponding with the sawtooth of the first arc saw blade; The first end of the first arc saw blade and the first end of the second arc saw blade pass through pinned connection; The first in command, its first end is fixedly connected with the first end of the first arc saw blade; The second in command, its first end is fixedly connected with the first end of the second arc saw blade; First arc saw blade is provided with Compress Spring near its first end place and the second arc saw blade between its first end place, Compress Spring one end is connected between the first end of the first arc saw blade and bearing pin (3), between the first end that the other end is connected to the second arc saw blade and bearing pin; When second end of the first in command and second end of the second in command apply pressure, Compress Spring stress deformation, the first arc saw blade and the second arc saw blade form opening, make to treat that beta pruning is dry and put into opening, discharge and apply pressure to the second end of two handles, the sawtooth of two saw blades is engaged on limb.
Preferably, the first arc saw blade is identical with the radian of the second arc saw blade.
Preferably, sawtooth and sawtooth tilt to first end.
Preferably, the first in command is shorter than the second in command.
Preferably, spring is torsion spring, is arranged on bearing pin.
In the present invention, two saw blades are clamped in the limb position needing lower saw under the action of the spring, sawtooth sawing limb is realized by continuous swing handle, due to the effect of spring, be not easy mobile during saw blade work, can ensure that lower saw position is accurate, and under the action of the spring, both sides sawtooth remains the pressure to limb, can remain operational stability, increase work efficiency; Further, because handle is long, operating personnel may stand in reciprocating rotation handle on the ground, make sawtooth saw limb back and forth, do not need to use ascending tool, easy to operate, saving cost.
Accompanying drawing explanation
Fig. 1 is a kind of beta pruning tool work structure graph that the embodiment of the present invention proposes;
Fig. 2 is a kind of beta pruning tools idle structure graph that the embodiment of the present invention proposes.
Embodiment
As depicted in figs. 1 and 2, the embodiment of the present invention proposes a kind of beta pruning instrument, comprising: the first arc saw blade 1, and sawtooth 11 is positioned at inner arc side, second arc saw blade 2, sawtooth 21 is positioned at inner arc side, corresponding with the sawtooth 11 of the first arc saw blade 1, the first end of the first arc saw blade 1 is connected by bearing pin 3 with the first end of the second arc saw blade 2, the first in command 4, and its first end is fixedly connected with the first end of the first arc saw blade 1, the second in command 5, and its first end is fixedly connected with the first end of the second arc saw blade 2, first arc saw blade 1 is provided with Compress Spring 6 near its first end place and the second arc saw blade 2 between its first end place, between the first end that Compress Spring 6 one end is connected to the first arc saw blade 1 and bearing pin 3, between the first end that the other end is connected to the second arc saw blade 2 and bearing pin 3, when second end of the first in command 4 and second end of the second in command 5 apply pressure, spring stress is out of shape, first arc saw blade 1 and the second arc saw blade 2 form opening, as shown in Figure 2, make to treat that beta pruning is dry and put into opening, discharge and pressure is applied to the second end of two handles, the sawtooth of two saw blades is engaged on limb, as shown in Figure 1, two saw blades are clamped in the limb position needing lower saw under the action of the spring, sawtooth sawing limb is realized by continuous swing handle, due to the effect of spring, be not easy mobile during saw blade work, can ensure that lower saw position is accurate, and under the action of the spring, both sides sawtooth remains the pressure to limb, operational stability can be remained, increase work efficiency, further, because handle is long, operating personnel may stand in reciprocating rotation handle on the ground, make sawtooth saw limb back and forth, do not need to use ascending tool, easy to operate, saving cost.
First arc saw blade 1 is identical with the radian of the second arc saw blade 2.Sawtooth 11 and sawtooth 21 tilt to first end, to increase the snap-in force to limb.The first in command 4 is shorter than the second in command 5.Spring 6 can change torsion spring into, is arranged on bearing pin 3.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
