Description

Technical Field

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

[0002] Grafting technology is one of the methods of artificial vegetative propagation of plants, which is to graft the branches or buds of one plant onto the stem or root of another plant so that the two connected parts can grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. The time and method of grafting vary according to plant variety, regional climate and nutritional status. For example, peach rootstock can be grafted in spring, summer and autumn, while branch grafting is generally carried out before budding in spring.

[0003] After searching, publication number CN215301696U is a rose grafting fixing clamp, which aims to solve the technical problems that the existing grafting method is labor-intensive and time-consuming and the grafting tape winding and binding easily causes the scion to break. The rose grafting fixing clamp mainly includes two clips, which are connected by a core shaft; the core shaft sleeve is provided with a torsion spring; the clip includes a handle piece and a clip body that are fixedly connected, and the clip body is arc-shaped; a flexible layer of matching shape is fixedly provided on the inside of the clip body; at least one of the clip bodies is provided with a scion bud opening. The utility model saves labor and time when used in grafting, greatly improves grafting efficiency and grafting quality, can be easily removed in time after the scion bears fruit, will not bind the scion, and can be reused. However, the utility model fixes the plant by the front clamp and the rear clamp, and the plant is usually thin at the top and thick at the bottom, resulting in a small contact area between the two clamps and the plant when the front clamp and the rear clamp clamp the plant, resulting in a poor clamping effect on the plant. Moreover, after the utility model clamps the plant, it will hang on the surface of the plant, which will cause pressure on the plant and cause the plant to bend, which will further cause cracks to appear at the grafting site of the plant, ultimately reducing the success rate of grafting.

[0004] To this end, a grafting clamp is proposed, which has the advantages of good clamping and fixing effect and can improve the success rate of grafting, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a grafting clip.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a grafting clamp, comprising a first clamping block and a second clamping block, the top and bottom of the first clamping block and the second clamping block are rotatably connected with connecting plates, a surface of one side of the first clamping block is provided with a plurality of threaded blind holes, and a first bolt is threadedly connected in the plurality of threaded blind holes, a surface of one side of the second clamping block is fixedly provided with a plurality of concave blocks, and a tie bar is rotatably connected in the plurality of concave blocks through a rotating rod, and a tensioning block is fixedly connected to one end of the tie bar, a through hole is provided on the top surface of the first clamping block and the second clamping block, and an insertion rod is inserted in the through hole, a threaded seat is welded on the surface of one side of the insertion rod, and a second bolt is threadedly connected in the threaded seat.

[0011] As a further description of the above technical solution: the first clamping block and the second clamping block are arranged in an arc shape on one side facing each other.

[0012] The utility model has the following beneficial effects:

[0013] The invention provides a plurality of bolts for clamping and fixing the grafted plant by setting the tie bars, and the plurality of tie bars arranged up and down are manually tightened by the tension block when the plant grafting is clamped and fixed. The surface of the tie bars is provided with a through groove. After tightening, the first bolt passes through the through groove to squeeze and fix the tie bars and the first clamping block. The plurality of tie bars can be selectively tightened according to the diameter of the plant not passing through the position, so as to prevent the problem of local loose fixation caused by different diameters of different positions of the plant. The clamping and fixing effect is good.
