Technical Field

[0001] The invention belongs to the technical field of fruit tree pruning devices, and in particular relates to an adjustable self-disinfecting citrus pruning shear. Background Art

[0002] When citrus trees grow to a certain size, they need to be pruned and their branches and leaves shaped and crowned. Traditional pruning shears are similar to scissors, and include two hinged rotating arms, one end of which is connected to the blade, and the other end is provided with a handpiece, which is manually pressed together to complete the pruning of citrus branches. If the citrus trees are more than two years old, the branches are thicker, and the manual pressing operation is both labor-intensive and inefficient, and is not suitable for large-scale operations.

[0003] On the other hand, in order to prevent bacteria and viruses from infecting citrus trees through the pruning ends of citrus branches and leaves, disinfectants need to be sprayed on the pruning ends of branches during the pruning process. The traditional method is to spray manually with a disinfectant bucket filled with disinfectant, which is inconvenient to operate, not very targeted, and wastes disinfectant. Summary of the invention

[0004] The purpose of the present invention is to provide an adjustable self-disinfecting citrus pruning shears, which overcomes the defects of the existing citrus pruning shears that they need to be manually pressed to achieve cutting, which is time-consuming and labor-intensive, and also requires a separate spraying of disinfectant.
