The novel fruit tree pruning shear has the advantages of convenient use, wide range of application, and convenient replacement of a cutting knife.

Description

technical field [0001] The invention relates to an auxiliary tool for fruit tree planting, in particular to a novel fruit tree pruning knife which is convenient to expand and contract. Background technique [0002] Fruit trees are trees with edible fruits. Fruit trees need to be pruned according to different planting environments and planting solar terms. Although fruit trees can be pruned before planting, they need to be pruned according to the specific conditions of the fruit trees after planting, because the newly planted trees cannot be pruned. Climbing, the current fruit tree pruning equipment has a single function and is not suitable for long-distance pruning. Therefore, a device that has a wide range of use and can be used for pruning fruit trees after planting is badly needed on the market. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a novel fruit tree pruning knife that is...

Problems solved by technology

[0002] Fruit trees are trees with edible fruits. Fruit trees need to be pruned according to different planting environments and planting solar terms. Although fruit trees can be pruned before planting, they need to be pruned according to the specific conditions of the fruit trees after planting, because the newly planted trees cannot be pruned. For climbing, the current fruit tree pruning equipment has a single function and is not suitable for long-distance pruning. Therefore, there is an urgent need for a device that can be used in a wide range and can be used for pruning fruit trees after planting.
