Description

Technical Field

[0001] The utility model relates to the technical field of grafting tools, in particular to a cutting device for grafted branches of trees. Background Art

[0002] As is well known, grafting is a skillful job. Through grafting, the yield and quality of crops can be improved by using high-quality scions. During grafting, the operator needs to make a tongue at one end of the grafted branch. The tongue is usually cut into shape by a grafting knife. However, making the tongue only with a grafting knife requires extensive operating experience. Otherwise, it is difficult to ensure the angle and flatness of the tongue end surface, which in turn affects the survival rate of the graft.

[0003] For example, a Chinese patent (publication number: CN210183962U) discloses a cutter for grafting fruit trees and flowers; the patent comprises a base plate and a blade, wherein a fixing block with a screw hole is symmetrically arranged on the base plate, and the blade comprises a first blade and a second blade which are symmetrically arranged. The patent can simultaneously cut the two sides of the scion by fixing the first blade and the second blade, and the cutting is completed with one cut. The cut scion surface is uniform in size and smooth, which is conducive to the fitting of the scion and the rootstock; however, the patent has a complex structure and is inconvenient to carry. During the grafting operation, a grafting knife for cutting the rootstock needs to be prepared separately, which is inconvenient to use. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses a cutting device for tree grafting branches.

[0005] In order to achieve the above-mentioned purpose of the invention, the present invention adopts the following technical solutions:

[0006] A device for cutting grafted branches of trees comprises a grafting knife, a handle and a sliding frame; protrusions with inclined tops are provided on both sides of one end of the handle, and the small ends of the protrusions extend out of the handle, and the tops of the protrusions are provided with sliding grooves; the tops of the two protrusions are provided with sliding frames, and the sliding frames are slidably engaged with the two sliding grooves; the sliding frame is provided with a positioning groove for making the blade of the grafting knife parallel to the tops of the protrusions.

[0007] Preferably, a groove for limiting the position of the graft is provided at the top of the handle and / or between the two protrusions.

[0008] Preferably, the groove is V-shaped or arc-shaped.

[0009] Preferably, a limiting bolt for locking the grafting knife is threadedly connected to the top of the sliding frame.

[0010] Preferably, one end of the slide groove corresponding to the small end of the protrusion is closed or provided with a limit block.

[0011] Preferably, the cross section of the slide groove is a dovetail or convex structure.

[0012] Preferably, the end of the handle facing away from the protruding portion is connected to a hanging rope.

[0013] Preferably, the handle body is provided with anti-slip grooves or wrapped with an anti-slip rubber sleeve.

[0014] During use, the graft is placed on top of the handle, with the tongue end of the graft passed under the sliding frame, and the blade of the grafting knife is placed in the positioning groove. The operator holds the handle with one hand and presses to fix the graft, while holding the handle of the grafting knife with the other hand, so that the blade of the grafting knife drives the sliding frame to slide along the top of the protrusion, and the grafting knife cuts the graft to form the tongue. Because the top of the protrusion is inclined, the sliding frame slides inclined. The sliding frame is provided with a positioning groove for aligning the blade of the grafting knife with the top of the protrusion. When the sliding frame slides, the blade of the grafting knife is always parallel to the top of the protrusion. The top of the protrusion is set at an angle that matches the tongue of the graft. Since the angle of the blade of the grafting knife is limited by the sliding frame, the angle of the tongue of the graft is also parallel to the top of the protrusion.

[0015] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0016] (1) By adopting the present invention to cut grafted branches, the tongue can be cut into a suitable angle, and the probability of forming the grafted branches in one cutting is greatly increased, which can reduce the probability of uneven tongue end faces of grafted branches caused by multiple cutting, thereby improving the survival rate of grafted trees.

[0017] (2) The utility model has a simple structure, a small size and is easy to carry.

[0018] (3) The present invention further provides a groove for limiting the position of the graft at the top of the handle and / or between the two protrusions. The groove is V-shaped or arc-shaped, that is, the graft can be pressed into the groove during use, which can effectively prevent the graft from rolling around on the top of the handle during cutting, further improving the probability of the tongue being formed.

[0019] (4) The present invention further has a limit bolt threadedly connected to the top of the sliding frame for locking the grafting knife, that is, the blade of the grafting knife can be fixed in the positioning groove by the limit bolt, thereby preventing the blade of the grafting knife from flipping up and down at will during the cutting operation, and effectively ensuring the flatness of the end face of the tongue.

[0030] It should be noted that the sliding frame 3 is an integrated structure, which can effectively ensure its stability.

[0031] It should be noted that the grafting knife 1 can be used not only for cutting the tongue, but also for cutting the opening of the rootstock, without the need for additional knife preparation.

[0032] During use, the graft is placed on the top of the handle 2, so that the tongue end of the graft is passed under the sliding frame 3, and the blade of the grafting knife 1 is placed in the positioning groove 5; the operator holds the handle 2 in one hand and presses to fix the graft, and holds the handle of the grafting knife 1 in the other hand, so that the blade of the grafting knife 1 drives the sliding frame 3 to slide along the top of the protrusion 8, and the graft is cut by the grafting knife 1 to form a tongue. The top of the protrusion 8 is set to an angle that matches the tongue of the graft. Since the angle of the blade of the grafting knife 1 is limited by the sliding frame 3, the angle of the tongue of the graft is parallel to the top of the protrusion 8, so that the tongue can be cut to a suitable angle, and the probability of forming it in one go is greatly increased, which can reduce the probability of the tongue end face of the graft being uneven due to multiple cutting, thereby improving the probability of the tree being grafted and surviving. Example 2

[0033] In actual use, it was found that due to the lack of limit and stable positioning of the graft, the graft easily rolled on the top of the handle 2 during cutting, resulting in failure of the tongue forming. In order to solve the above technical defects, this embodiment is further improved.
