Tree branch grafting grooving leaning joint knife

Technical Field

The utility model belongs to the technical field of horticulture instrument, a branch grafting grooving is by connecing sword is related to.

Background

Grafting is one of artificial propagation methods of plants. That is, a branch or bud of one plant is grafted onto a stem or root of another plant, and the two parts joined together are grown into a complete plant. The grafting method is divided into a branch grafting method and a bud grafting method. The grafting is carried out by utilizing the function of wound healing of the plant after being wounded.

The implementation mode of grafting is as follows: cutting a hollow groove on the branch, placing the root of the branch to be grafted in the hollow groove, fixing the branch on the branch by using an adhesive tape, and completing grafting after the hollow groove is self-healed. The tool used for cutting the empty groove in the prior art is a common blade, and the whole branch is easily cut excessively if force is improperly applied in the branch cutting process, so that the whole branch is broken.

Fig. 2 is a schematic view of a cross-sectional structure between the support bar and the handle.

In the figure, 1, a handle; 2. a support bar; 3. a cutter bar; 4. a notch; 5. a bending section; 6. cleaning the block; 7. a collar; 8. a ring-shaped groove; 9. a ring-shaped snap ring; 10. and (4) a bolt.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, this branch grafting grooving inarching sword includes handle 1, bracing piece 2 and cutter arbor 3, the scalable setting of bracing piece 2 is on handle 1, cutter arbor 3 sets up the tip at bracing piece 2, set up the notch 4 of rectangular shape on the cutter arbor 3, bracing piece 2 has a plurality of kinks 5, the sharp at the sharp and the handle 1 center pin place at cutter arbor 3 place forms the contained angle, it is equipped with a clearance piece 6 to slide in notch 4, the edge of clearance piece 6 is pasted in notch 4 bottom surfaces.

The in-process of using, paste through 3 tip of cutter arbor and dig and cut on leaning on the branch, this process is comparatively slow, because no longer adopt the blade directly to cut into in the branch, so be difficult to the cutting excessively to lead to the branch rupture, after piling up a large amount of fibre thing in notch 4, can adopt the form of removing clearance piece 6 to strike off the abandonment fibre thing in notch 4. Because different branches are located at different positions, some branches are deep, and the cutter bar 3 needs to penetrate through a plurality of branches and leaves to reach the destination, the cutter bar 3 is designed to be capable of adjusting the length relative to the handle 1.

As shown in fig. 2, a cavity is formed in the handle 1, a lantern ring 7 is fixedly arranged in the cavity, a plurality of circular grooves 8 are dug on the inner wall of the lantern ring 7, the circular grooves 8 are arranged at equal intervals, a circular snap ring 9 is fixedly arranged on the support rod 2, the lantern ring 7 is made of a soft memory material, the circular snap ring 9 is clamped on one circular groove 8 of the lantern ring 7, the inner wall of the lantern ring 7 can be extruded and deformed by the circular snap ring 9 in the moving process of the support rod 2 and can be moved into the other adjacent circular groove 8, a fixing hole is transversely formed in the handle 1, a plurality of connecting holes are formed in the support rod 2, bolts 10 can be detachably arranged in the two connecting holes which are aligned with the fixing hole and are aligned with each other, and the distance between the two adjacent connecting holes is consistent with the distance between the two adjacent circular grooves 8.

When the cutter arbor 3 is adjusted for 1 length of handle at needs, extract bolt 10, bracing piece 2 can stretch out and draw back the adjustment for handle 1 this moment, then push and pull the bottom of bracing piece 2 hard, make circle shape snap ring 9 break away from original circle shape inslot 8, and block to the circle shape inslot 8 of another suitable position in order to accomplish the location, then because two adjacent circle shape inslots 8 and two adjacent setting of linking hole interval unanimity, so still have an linking hole and fixed orifices alignment this moment, insert back bolt 10 again and just can accomplish fixing between them.

It is to be understood that in the claims, the specification of the present invention, all "including … …" are to be interpreted in an open-ended manner, i.e. in a manner equivalent to "including at least … …", and not in a closed manner, i.e. in a manner not to be interpreted as "including … … only".

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
