Description

Technical Field

[0001] The utility model relates to the technical field of grafting knives, in particular to a seedling grafting knife. Background Art

[0002] Grafting is a propagation method that grafts the bud or branch of one plant onto another plant so that the two parts joined together grow into a complete plant. The bud or branch grafted on is called the scion, and the plant to be grafted is called the rootstock. The key to successful grafting is to closely combine the cambium of the scion and the rootstock. Grafting methods are divided into branch grafting and bud grafting, and grafting is carried out by utilizing the wound-healing function of plants.

[0003] Grafting requires the use of a grafting knife to cut the branches and buds. During the production process of the grafting knife, it is often inconvenient to assemble. After being damaged during use, it is inconvenient to replace the knife handle or the knife head. Therefore, those skilled in the art have provided a seedling grafting knife to solve the problems raised. Content of the Utility Model

Four positioning posts are fixedly installed on one side of the connecting sleeve. One side of the connecting sleeve is also inserted with a connecting rod. An annular block is fixedly sleeved on the side surface of the connecting rod. The positioning posts penetrate through the annular block. A nut is installed on the connecting rod through a thread. The nut is arranged inside the connecting sleeve. The connecting sleeve and the cylinder are connected by a bolt. One end of the connecting rod is fixedly installed with a knife head, which is convenient for assembling the grafting knife and can replace the knife handle or the knife head.

[0007] Preferably, the connecting rod is inserted into one end of the cylinder, and the stability of the knife head is better.

[0008] Preferably, two cutouts are opened on the side surface of the connecting sleeve. A notch is opened on one side of the cutout. The bolt penetrates through the notch. The notch can fit with the bolt head, and the notch can position and install the connecting sleeve.

[0009] Preferably, an inner cavity is opened in the knife handle. A threaded pipe is installed in the inner cavity through a thread. One end of the threaded pipe is fixedly installed with a rotating plate. Anti-slip lines are arranged on the side surface of the rotating plate, and spare items required for grafting can be placed in the inner cavity.

[0010] Preferably, a sleeve ring is rotatably installed at the center of the side surface of the rotating plate, which is convenient for hanging the whole.

[0011] In summary, the utility model includes the following beneficial technical effects:

[0012] 1. The positioning post passes through the annular block for positioning. The connecting rod and the nut are connected by threads, so that the connecting rod can be fixed.
