Crescent moon type scissor saw

Abstract

The invention discloses a crescent moon type scissor saw, belonging to the technical field of garden pruning tools. The crescent moon type scissor saw comprises a scissor body, a scissor shaft and a scissor handle which are sequentially arranged from top to bottom, wherein the scissor body comprises a cutting edge, the scissor handle comprises a scissor handle I and a scissor handle II, the cutting edge comprises a sawtooth edge part and a flat edge part, the sawtooth edge part comprises a sawtooth edge I and a sawtooth edge II, and a concave arc part of the sawtooth edge I is opposite to a concave arc part of the sawtooth edge II; the flat edge part comprises a flat edge I and a flat edge II, and a concave arc part of the flat edge I is opposite to a concave arc part of the flat edge II;and a transition part is arranged between the sawtooth edge part and the flat edge part. According to the crescent moon type scissor saw, a pruner and a saw are perfectly combined, so that the tediousoperation for replacing tools repeatedly is avoided; branches are firmly grabbed in the use process; and the labor is saved, and the pruning, sawing and cutting efficiencies are high.

Description

Technical field [0001] The invention relates to the technical field of garden pruning tools, in particular to a crescent type scissors saw. Background technique [0002] Pruning is an important part of garden management and maintenance. As the saying goes, "seven points for management, three points for pruning". Through reasonable pruning, a beautiful tree shape can be cultivated, and by pruning, the reasonable distribution of nutrients can be adjusted, inhibiting excessive growth, promoting flower bud differentiation, achieving early flowering and fruiting of young trees, and prolonging the blooming and fruiting period. Rejuvenate old trees. [0003] Traditional pruning is generally used together with pruning shears and hand saws. The pruning shears cut thin branches, the hand saw cuts large branches, and when pruning branches of different diameters, the pruning shears and hand saws are replaced back and forth. It is often necessary to load the pruning shears and the handsaw at ...

AI Technical Summary

Problems solved by technology

[0003] Traditional pruning is generally used in conjunction with pruning shears and hand saws. The pruning shears cut off thin branches, and the hand saw saws off large branches. It is often necessary to load pruning shears and hand saws at the same time, which is not only extremely inconvenient to use back and forth, but also increases the labor load of workers

[0004] Moreover, the blades of traditional pruning scissors are designed with straight sides or single-sided crescents, which often cannot firmly grasp the branches during the cutting process. Workers often need to fix the branches with one hand and apply force to the pruning shears with the other hand to cut the branches. Branch shears can only get the strength of the worker's one hand, which not only hinders the pruning task, but also makes the worker's single hand more prone to fatigue

[0005] Moreover, traditional hand saws mostly use the principle of linear reciprocating sawing, such as Figure 14 As shown, in the process of reciprocating sawing, the hand saw 16 can only apply force to one side of the branch 13, and the sawing efficiency is low.
