Abstract

The utility model relates to a pair of long arm type shears for fruit trees. A blade of the utility model is composed of a fixed blade and a movable blade provided with a curve neck, and a shear handle made into a long arm type structure is connected to the tail end of a neck part arranged on the fixed blade, wherein, each blade can form a shearing mouth part and a clamping mouth part, and the movable blade is movably clamped on the fixed blade. The tail parts of the two blades are respectively provided with a compression spring and a positioning clamping block for installing a steel cable with small diameter, wherein, the other end of the steel cable is arranged on an operating grip of the shear handle. The shearing mouth of the utility model can cutting and shearing branches, while the clamping mouth of the shears can clamp and break the branches, so that fruit growers can prune branches by standing on ground. The utility model is safe and convenient in operation, and suitable for pruning early blossom, thinning flowers and fruits of fruit trees and picking fruits.

Description

Long-armed type pruning fruit tree cutter

The utility model relates to the pruning fruit tree cutter of scissors, particularly a kind of long-armed type that a kind of pruning (fruit tree) branch uses, is suitable for orchard worker or gardener and uses as the instrument of pollard.

The scissors that existing pruning fruit tree branch is used adopts two of traditional type more and is movably hinged the company of (or movable riveted joint) formula the blade unit structure, every blade all is divided into roughly the same cutter head (knife edge part) and hilt handle portion, the shortcoming that exists in the use mainly is: because of the hilt handle too short, to taller and bigger fruit tree, could operate after often needing cat ladder to ascend a height, not only had a strong impact on the safety of orchard worker's work, operating efficiency is also undesirable.In addition, existing pruning shear can only be used for cutting off branch, can not be used to the branch that fractures.

The purpose of this utility model is a kind of long-armed type pruning fruit tree cutter of design, make orchard worker or gardens staff only need stand in ground and taller and bigger fruit tree or other trees are carried out safe pruning (comprise flower thinning, fruit thinning and pluck fruit) with regard to realizing, and operate easily easyly, can alleviate orchard worker's labour intensity.

The utility model is realized with following technical scheme, it comprises blade and hilt handle, it is characterized in that blade is to constitute by the diverse fixed blade of two plate shapes with movable blades bent neck and that can make expanding-contracting action, described hilt handle is made the long-armed type structure, it installs the neck tail end place that is connected fixed blade, described every blade can form the scissors mouth knife edge part of (or claiming to cut off mouth) except being provided with, also be provided with the clamp part of clamp mouth at the back side of scissors mouth, and cooperatively interact to do respectively to draw and cut the action of (break) branch and the clamping branch that fractures and move, wherein the cervical fixation at fixed blade is provided with two positioning and guiding intermediate plates, movable blades with bent neck is movable clamping connection (socket) on fixed blade by this guiding intermediate plate, respectively being provided with one at the afterbody of fixed blade and movable blades is used for fixing the location fixture block that the path steel wire rope is used is installed, between two location fixture blocks, the compression spring is installed also, the other end of path steel cable is installed in (the path steel wire rope safeties that the soft brake type of similar bicycle is used) on the operating handle that is positioned at long-armed type hilt handle tail end, loosen the operating handle of long-armed type hilt pommel portion, under the effect of compression spring, movable blades can stretch out forward along the determined direction of positioning and guiding intermediate plate, make scissors mouth and clamp mouth open (warming-up exercise of making pollard), clutch the operating handle of long-armed type hilt pommel portion, under the tension of path steel cable, movable blades shrinks backward and clamps and can do respectively to draw the poll action and/or clamp the branch action that fractures.

The utility model is according to orchard worker's actual needs design, two insert design are become to have the fixed blade and the movable blades of positioning and guiding effect, wherein with the movable blades of bent neck, its bent neck portion can make the scissors mouth can do the effect of cutting-up and shearing simultaneously to branch when cutting off work, can cut off thicker branch (generally can cut off the branch of diameter below 1cm) so more effortlessly.Because of the clamp mouth is arranged in scissors back side design, but it also clamp with fracture the branch of diameter below 1cm, also can take the fruit of the long above carpopodium of 2cm from tree.In addition, long-armed type hilt handle can adopt the sleeve pipe of pivot bush unit to replace, be convenient to install and remove and carry, and because of operator (orchard worker) when operating can stand directly on the ground pollard, simple and safe operation, labour intensity hangs down high efficiency.Be very suitable for to pruning fruit tree early blossoming, flower thinning, fruit thinning and pluck fruit, also conveniently prune the higher flowers and trees of growing way.

Below in conjunction with accompanying drawing embodiment concrete structure of the present utility model is elaborated.

Fig. 1 is a kind of structural representation of the utility model pruning shear.

Fig. 2 is that the scissors mouth and the clamp mouth of this pruning shear loosened the automatic open structural representation in back.

Wherein: 1～movable blades, 2～fixed blade, 3～scissors mouth (also claiming to cut off mouth), 4～clamp mouth, 5～positioning and guiding intermediate plate, the bent neck of 6～movable blades, the neck afterbody of 7～fixed blade (being neck tail end place), 8～path steel wire rope location fixture block, 9～compression spring, 10～path steel wire rope (the quite automobile-used path flexible steel cable of bicycle callipers brake), 11～long-armed type hilt handle (available sleeve pipe replacement), 12～path steel wire rope operating handle.

With reference to accompanying drawing as can be known, the also available telescopic long handle-bar grip structure of long-armed type hilt handle of the present utility model replaces, and this sleeve pipe can directly be actively socketed on the neck tail end place of fixed blade.
