Description

Technical Field

[0001] The utility model relates to the technical field of fruit branch shears, in particular to a pair of fruit branch shears with adjustable cutting diameter. Background Art

[0002] The crown of a fruit tree expands with the growth of tree age. Too many branches and leaves will inevitably lead to the consequences of dense outside and hollow inside, premature aging of the tree, serious alternate bearing, and reduced fruit yield and quality. In the process of fruit tree cultivation, fruit branch shears are needed to prune the fruit trees. Fruit tree pruning refers to the technical measures of cutting off part of the fruit tree's nutritional organs to adjust the crown structure and update the branch composition. It is conducive to regulating the reasonable distribution of branches and leaves, the growth and fruiting and branch composition ratio, and can also balance the growth potential between groups of plants and between the main branches on a plant, so as to achieve balanced yield and facilitate management. In addition, it is also a means to coordinate the growth of the aboveground part and the root system.

[0003] The fruit shears are composed of two upper and lower blades that cut and prune each other. The operator can prune the fruit tree by applying force to the upper and lower blades corresponding to the handles. At present, the opening size of most fruit shears remains fixed. The operator needs to manually compare the fruit trees with different root and stem sizes, and then manually cut them repeatedly, which is cumbersome and consumes a lot of labor resources, which is not conducive to operation.

[0004] In addition, during use, the operator may accidentally start the fruit branch shears, resulting in unsafe use. Summary of the invention
