Description

Technical Field

[0001] The utility model belongs to the technical field of agronomic grafting, and in particular relates to an agronomic grafting device. Background Art

[0002] Grafting is one of the artificial propagation methods of plants. It is to graft the branch or bud of one plant onto the stem or root of another plant, so that the two parts grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. Grafting is carried out by using the healing function of plants after being injured.

[0003] For example, a Chinese patent with the announcement number CN216254100U discloses a grafting device for agronomists, including a first fixing plate, a first spring fixedly connected to one side of the first fixing plate, a second fixing plate fixedly connected to one side of the first spring, and a first rectangular block and a second rectangular block fixedly connected to the surfaces of the first fixing plate and the second fixing plate. The grafting device for agronomists is arranged by the coordination of the first fixing plate, the first spring, the second fixing plate, the first rectangular block, the threaded rotating rod and the rectangular hole. When in use, the staff clamps the first fixing plate and the second fixing plate on the crops to be grafted, the first spring can adjust the distance between the first fixing plate and the second fixing plate according to the thickness of the crops, and when the first fixing plate and the second fixing plate are clamped on the crops, the threaded rotating rod on the first rectangular block is rotated to clamp the threaded rotating rod into the rectangular hole, and then the threaded rotating rod is rotated, so that the crops to be grafted can be fixed.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when the device fixes the grafted crops, due to the different thickness of the grafted crops and the uneven surface of some crops, the crop surface is easily scratched and the fixation is unstable when the device is clamped and fixed. In addition, when the grafting position is high, the two support frames are not long enough, resulting in unstable fixation. In view of this, we propose an agricultural grafting device.
