Abstract

The invention discloses a handhold fruit shear. The handhold fruit shear comprises upper and lower shearing blade components, upper and lower handles, a universal driving shaft component, a latch device and a spring device; the upper and lower shearing blade components are located at the front end of a fruit shear, and respectively connected to the upper and lower handles through the universal driving shaft component; the spring device is arranged at insides of the upper and lower handles, and used for controlling the opening degree of a fruit shear opening; the latch device is arranged at the insides of the upper and lower handles, and used for controlling the fruit shear under the closing state. The handhold fruit shear cannot contact the surface of a fruit, and pick or thin fruits without hands; besides, the handhold fruit shear ensures that the fruits cannot fall to the ground.

Description

Hand-held is repaiied fruit and is cut

Technical field

The present invention relates to a kind of fruit thinning fruit picking tool, particularly a kind of hand-held is repaiied fruit and is cut.

Background technology

During gardening cultivation of fruit tree, generally unnecessary branch is wiped out using secateurs, have manual secateurs (for example CN101084723A, CN103141314A), also there are electric branch scissors (such as CN102771323A).But remove unnecessary or sense The real usually not specific purpose tool of disease fruit, existing way is directly to remove unnecessary fruit and susceptible fruit with hand.This Softening There are problems that two：First, during normal fruit thinning, the absciss layer of fruit carpopodium is not yet formed, and manual rigid pulling can cause to draw Hinder fruitful branch, affect reserved fruit growth；Second, susceptible fruit is removed, because fruit surface produces large area scab, can be direct Cause to pollute staff, when normal fruit is contacted again secondary pollution can be caused, cause normal fruit susceptible.Additionally, medium and small at present Harvesting of the type with handle fruit is generally directly plucked using staff.The fruit softer for some quality, such as strawberry, apricot, solute peach Deng, directly being plucked with hand getting can cause fruit surface machinery wound, affect storage period；And for some surfaces the fruit of raw wax, Such as apple, persimmon, plum, directly being plucked with hand getting can cause fruit surface wax to come off, and affect commodity.It is therefore desirable to sending out A kind of bright instrument, can be not only used for removing unnecessary and susceptible fruit during fruit growth, prevent fruit from dropping ground；Can also be used for Picking fruit, while not contacting fruit surface, realizes contactless fruit picking.

The content of the invention

Present invention aims to prior art requirement disappearance problem, there is provided a kind of hand-held is repaiied fruit and cut, and can not connect Tactile fruit surface, realizes contacting fruit picking or fruit thinning without hand, and guarantees that fruit does not fall out underground.

For achieving the above object, present invention employs following technical scheme：A kind of hand-held repair fruit cut including：Up and down Shear-blade component, upper lower handle, include couple axle component, locker and spring assembly；Upper lower shear blade component is located at and repaiies The front position that fruit is cut, by couple axle component upper lower handle is connected to；Spring assembly is arranged at lower handle inner side, uses The stretching degree of fruit scissors mouth is repaiied in control；Locker is arranged at lower handle inner side, repaiies fruit for control and cuts in closure State.

Further, upper lower shear blade component includes respectively upper lower shear blade, and upper lower shear blade back-end central sets Fixed screw holes are put, the both sides of screw hole are provided with fixing hole；The centrally disposed fixed screw holes of couple axle component, the both sides of screw hole There is projection, projection is used to match with upper lower shear blade fixing hole, and then upper lower shear blade is fixedly connected on into upper assistant Handle.

Further, fixing hole is multiple, is shaped as rectangle, circle, ellipse or other geometries；It is corresponding prominent It is also multiple to rise, and is shaped as rectangle, circle, ellipse or other geometries.

Further, upper shear-blade component also includes being fixed on the upper fixator of shear-blade, lower shear blade group Part also includes being fixed on the lower fixator of lower shear blade.

Further, upper and lower fixator be zigzag, wherein zigzag fashion be V-type, the width and depth adjustable of V-groove.

Further, upper and lower fixator is waveform, and its medium wavelength and wave height are adjustable.

Further, upper lower shear blade is put the first edge on a knife or a pair of scissors or is not put the first edge on a knife or a pair of scissors or one of them puts the first edge on a knife or a pair of scissors.

Further, locker includes：L-type securing rod, slide block connecting rod, slide block, slide block is slidably arranged in slide link On, securing rod is fixed on handle or lower handle inner side, and corresponding slide block connecting rod is fixed on lower handle or upper handle inner side.

Further, spring assembly includes：Upper lower spring fixing button, spring, upper lower spring fixing button is individually fixed in Lower handle inner side, the two ends of spring are individually fixed on lower spring fixing button.

Further, upper lower shear blade is linear pattern or the arc or other geometries that bend towards knife back side.

Further, upper lower handle be shaped as " C " type or multistage arc or other meet grasp ergonomics shape.

The hand-held of the present invention is repaiied fruit and is cut, simple structure, easy to use, and it is unnecessary to can be not only used for being removed during fruit growth And susceptible fruit, prevent fruit from dropping ground；Picking fruit is can also be used for, while not contacting fruit surface, realizes contactless adopting Really.

Specific embodiment

Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.

Reference picture 1-9, corresponding to present pre-ferred embodiments hand-held repair fruit cut, it is mainly used in fruit growth process In remove unnecessary and susceptible fruit, prevent fruit from dropping ground；Picking fruit is can also be used for, while not contacting fruit surface, real Existing contactless fruit picking.It includes shear-blade component 1, lower shear blade component 2, lower c-type handle 3, upper c-type handle 4, linkage Shaft assembly 5, locker 6, spring assembly 7；Upper lower shear blade component 1 and 2 is located to be repaiied the front position cut of fruit and connects respectively On upper and lower c-type handle 4,3, wherein upper shear-blade component 1 includes upper shear-blade 9, lower shear blade component 2 is cut under including Cutting edge 8；Upper lower shear blade 9,8 is put the first edge on a knife or a pair of scissors and for linear pattern in the present embodiment, but it is linear pattern that the present invention is not limited to it, Can also be the arc or other shapes for bending towards knife back side.
