Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a novel fruit tree pruning hand saw. Background technique [0002] Fruit tree refers to the general term of perennial plants and their rootstocks that can provide edible fruits and seeds. The wood of many fruit trees is an excellent material for defense industry, construction industry and carving technology. Fruit trees will grow many branches during the growth process, but most of these branches are useless and will absorb the nutrients of the fruit tree, so these useless branches need to be pruned, but in the process of pruning, when encountering small branches, use pruning hands Saw pruning is not very convenient, and you need to carry a pruning knife for pruning. However, pruning of fruit tree branches is usually performed at high altitudes, and it is inconvenient to carry a large number of tools for climbing operations. Therefore, we propose a new type of fruit tree pr...

Fruit trees will grow many branches during the growth process, but most of these branches are useless and will absorb the nutrients of the fruit tree, so these useless branches need to be pruned, but in the process of pruning, when encountering small branches, use pruning hands Saw pruning is not very convenient, and you need to carry a pruning knife for pruning. However, pruning of fruit tree branches is usually performed at high altitudes, and it is inconvenient to carry a large number of tools for climbing operations. Therefore, we propose a new type of fruit tree pruning hand saw

[0003] For example, the patent of application publication number CN207083560U discloses a new type of fruit tree pruning hand saw, including a saw blade, one side of the saw blade is provided with a chute, the top of the inner wall of the chute is provided with a slider, and the slider is located at One end of the outside of the chute is fixedly connected with a connecting rod, the bottom of the slider is fixedly connected with a block, the bottom of the inner wall of the chute is provided with a snap-in groove suitable for the block, and the bottom of the connecting rod One side of the fruit tree is fixedly connected with a blade, but the new fruit tree pruning hand saw is inconvenient to trim the branches, it is inconvenient to replace the saw blade, and it is inconvenient to use
