Description

Technical Field

[0001] The utility model relates to the technical field of blade assemblies, in particular to a pruning blade assembly. Background Art

[0002] Horticulture, that is, garden cultivation, the cultivation and breeding techniques and production and management methods of fruit trees, vegetables and ornamental plants, can be correspondingly divided into fruit tree gardening, vegetable gardening and ornamental gardening. The term gardening originally referred to the cultivation of plants in fenced gardens. Although modern gardening has long broken this limitation, it is still a more intensive cultivation and management method than other crop planting. Horticulture is an integral part of the planting industry in agriculture. Horticultural production is of great significance for enriching human nutrition and beautifying and transforming the human living environment. Horticulture simply refers to the cultivation methods of crops such as flowers, vegetables, and fruit trees. More precisely, it refers to the cultivation and breeding techniques of vegetables, fruit trees, flowers, edible fungi, ornamental trees, etc., which are generally more sophisticated and correspondingly divided into fruit tree gardening, vegetable gardening and ornamental gardening. When carrying out gardening work, a variety of tools are needed to prune trees or flowers. In order to ensure the beauty of the trees and make them grow healthier, it is necessary to use pruning tools to trim the excess branches of the trees.

[0003] After searching, a Chinese patent with patent publication number CN219146209U discloses a pruning blade, including a main steel blade holder, the surface of which is fixedly connected to a main cutting shear body, a group of auxiliary cutting shear handles provided on the top surfaces of the main steel blade holder and the main cutting shear body, a plurality of mounting holes provided on the surface of the auxiliary cutting shear handle, and a plurality of fixing bolts provided on the surface of the main cutting shear body. The utility model, through the combination of the main steel blade holder and the auxiliary cutting shear handle, enables the main pruning blade and the cutting blade provided on the surface to cooperate with each other to prune the tree, and at the same time, through the provision of a protective block, the main steel blade holder and the auxiliary cutting shear handle can be fixedly assembled, and the hand of the person who replaces the blade can be prevented from being scratched due to the lack of protective measures on the blade, and the multiple connection channels provided on the surface make it easier for the person to assemble the blade with the pruning equipment.

[0004] However, the above design still has some shortcomings. In the above design, the protective block is used to protect the blade when it is disassembled and assembled to avoid scratches on people's hands. However, when the blade is installed with the protective block, due to the lack of an effective positioning mechanism, the blade may deflect to a certain extent in the protective block, which will affect the subsequent pruning effect of the blade on the branches.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0008] As a further solution of the present invention: a plurality of cutting blades are evenly distributed at equal intervals on both sides of the first blade.

[0009] As a further solution of the present invention: a second blade is provided on the front end surface of the first blade, and a third blade is provided on the rear end surface of the first blade.

[0010] As a further solution of the present invention: the second blade and the third blade are provided with a plurality of saw teeth evenly distributed at equal intervals on both sides.

[0012] As a further solution of the present invention: the number of the card slots and the number of the card blocks are both three.

[0013] The utility model has the following beneficial effects:

[0014] (1) Through the structural design of the first blade, U-shaped protective block, locking bolt, second nut, mounting hole, card slot, card block and through hole, the first blade in the U-shaped protective block can be effectively positioned, thereby preventing the first blade from being offset in the U-shaped protective block, thereby ensuring the pruning effect of the blade on the branches in the later stage, and at the same time, it can be convenient to disassemble and replace the first blade, which is simple to operate and convenient. It solves the problem that the protective block is used to protect the blade when it is disassembled and assembled, thereby avoiding scratches on the hands of personnel. However, when the blade is installed with the protective block, due to the lack of an effective positioning mechanism, the blade may be deflected to a certain extent in the protective block, thereby affecting the pruning effect of the blade on the branches in the later stage;

The cutting head and the serrations cooperate with each other to achieve different cutting effects on the branches, thereby improving the cutting effect. At the same time, by cooperating with the fixing hole, the fixing rod and the first nut, the second blade and the third blade can be easily replaced, thereby ensuring the efficiency of pruning.
