Abstract

The utility model relates to a grafting shears, which is a new working tool for fruit trees. The grafting shears comprises a handle of the support base axle (2), a handle of the shears (5), a supporting axle arm (6), a cutting support base (8), a torsion spring (9), a spacer pin (10), a clamping plate (11), etc. The grafting shears is characterized in that the grafting branch or the rootstock is clamped by the cutting support base (8) and the clamping plate (11), the grafting orifice is opened on the grafting branch or the rootstock by the cutting edges arranged on the front of the handle of the shears (5), and the angle and length of the grafting orifice is controlled by two plain faces of a sloped slotted hole arranged on the middle part of the cutting support base (8) and the spacer pin (10) arranged on the handle of the support base axle. The utility model has the advantages of simple structure, convenient operation. The grafting orifice is regular. The grafting orifice and the rootstock orifice are in full accord, compared with the artificial grafting, the plant percent can be raised by more than 5%. The efficacy can be raised remarkably, the labor intensity can be reduced, the technical requirements for the grafting people can also be reduced, and the utility model is suitable for ordinary persons.

Description

Grafting shears

The utility model belongs to the gardening field, relates to the power tool that a planting fruit-trees treelet grafting is used.

At present, the fruit tree treelet graft technology that is carried out in the production of fruit trees mainly is to carry out grafting with hand cutter and some coarse instruments, and not only to operating personnel's specification requirement height, and labour intensity is big, and inefficiency influences survival rate.

The purpose of this utility model provides a kind of novel fruit-tree grafting and cuts, be to adopt cutting bearing (8) and clamp pressing plate (11) with scion branch or stock clamping, the instrument of the scion mouth on scion or the stock being cut easily by the anterior blade of scissors handle (5) then.

The purpose of this utility model is achieved in that grafting cuts by bearing axle handle (2), scissors handle (5), supporting armshaft (6), bolt assembly (7), cutting bearing (8), torsion spring (9), spacer pin (10) and clamp pressing plate (11) composition.Cutting bearing (8) with clamp pressing plate (11) by supporting armshaft (6) hinged after, be installed on the preceding end bearing axle (13) of bearing axle handle (2), thereby constituted the main part that this grafting is cut.The bearing axle (13) of bearing axle handle (2) front end is 31 ° with the angle of handle (2) straightway, bearing axle (13) middle part is equipped with spacer pin (10), with this angle and fixed bearing sleeve (14) of controlling otch, promptly cut the main part of bearing (8).Cutting bearing (8) is loose-leaf structure with the two-part front end of clamping pressing plate (11), the loose-leaf part that to be cut bearing (8) by the bolster that supports armshaft (6) front end is hinged with the loose-leaf part that clamps pressing plate (11), and torsion spring (9) is installed in the middle part of loose-leaf structure.The middle part of cutting bearing (8) is divided into the tubular greater than semicircle, a slotted hole that tilts is cut in the outside of cylinder, it is 35 ° circumferential slotted hole that the axis normal of the bearing sleeve at rear portion (14) and cylinder, bearing sleeve (14) middle part have a central angle, in order to the shape of control otch.The middle part of clamping jaws (11) is the semi-cylindrical of concave crown, and the rear portion is low tabular of middle protruding periphery, so that the firm grip branch.During work, clamping pressing plate (11) opens under the effect of torsion spring (9) automatically, after being inserted in scion branch or stock, to cut bearing (8) and clamp pressing plate (11) and tight with hand, at this moment branch is clamped, another hand operated bearing axle handle (2) and scissors handle (5), twice of two plane shear of edge cutting bearing (8) middle part inclined elongate, at this moment the scion mouth on scion or the stock is just easily cut, and has so just realized the purpose of this utility model.

The utility model has the advantages that: simple in structure, easy to use, cost is low, otch is neat, guarantees the in full accord of scion and stock otch, thereby it is big more than 5% to improve survival rate than artificial grafting.Effect can be improved more than 20 times, labour intensity can be reduced again greatly and grafting personnel's specification requirement.All can use the ordinary person.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model, and Fig. 2 is the A-A profile among Fig. 1, and Fig. 3 is the B-B profile among Fig. 1.

In the accompanying drawings, 1. spacing belt, 2. bearing axle handle, 3. spacing pole, 4. conicalplate-coil spring, 5. scissors handle 6. supports armshaft, 7. bolt assembly, 8. cutting bearing, 9. torsion spring, 10. spacer pin, 11. clamp pressing plates, 12. stiffeners, 13. bearing axles, 14. bearing sleeves.

With reference to accompanying drawing, it is by bearing axle handle (2) that grafting is cut, scissors handle (5), and supporting armshaft (6), cutting bearing (8), torsion spring (9), spacer pin (10) clamps pressing plate (11); And spacing belt (1), spacing pole (3), conicalplate-coil spring (4) is formed.Cutting bearing (8) with clamp pressing plate (11), torsion spring (9) by supporting armshaft (6) hinged after, be installed on the preceding end bearing axle (13) of bearing axle handle (2), to constitute the main part that this grafting is cut.Bearing axle (13) middle part is equipped with spacer pin (10), with this angle and fixed bearing sleeve (14) of controlling otch, promptly cuts bearing main parts such as (8).Cut bearing (8) and be loose-leaf structure with clamping the two-part front end of pressing plate (11), it is hinged with clamping pressing plate (11) to cut bearing (8) by the bolster that supports armshaft (6) front end, and torsion spring (9) is installed in the middle part of loose-leaf structure.

Its course of work or using method are such: the right hand is held bearing axle handle (2) and scissors handle (5), left hand takes off spacing belt (1), at this moment, bearing axle handle (2) opens under the effect of conicalplate-coil spring (4) automatically with scissors handle (5), clamping pressing plate (11) simultaneously also opens under the effect of torsion spring (9), after being inserted in scion branch or stock, will cutting bearing (8) and clamp pressing plate (11) and tight with left hand, to clamp branch.Right-hand operated bearing axle handle (2) and scissors handle (5), along two plane shears twice of cutting bearing (8) middle part inclined elongate, the scion mouth on scion at this moment or the stock is just easily cut.
