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. Work

Embodiment 1

[0048] Such as figure 1 As shown, the teeth of the serrated edge I7 are single oblique serrations 11, the teeth of the serrated edge II72 are single oblique serrations 11, and the teeth of the serrated edge I71 are inclined toward the 3 end of the handle, and the serrations The inclination direction of the tip of the blade Ⅱ72 is the same as that of the tip of the sawtooth of the blade I71; the inclination angle α of the blade of the sawtooth part 7 in the vertical direction of the scissors saw is in the range of 75°≤α <90 degrees, the tooth groove 73 at the tooth root of the serrated edge portion 7 is connected with a chip discharge groove 74.

[0049] The 3 heads of the knife handle are provided with a return device. The return device is a locking mechanism 5. The locking mechanism 5 includes a buckle 311 and a groove strip 51 matched with the buckle. The buckle 311 is arranged on the handle head of the knife handle I 31 On the upper side, one end of the groove strip 51 is con...

Embodiment 2

[0054] Such as figure 2 As shown, the biggest difference between this embodiment and Embodiment 1 lies in the difference in the return device. In this embodiment, the return device on the head of the knife handle 3 is a spring mechanism 6. The spring mechanism 6 includes a return spring 61. One end of 61 is connected with the head of the knife handle I 31, and the other end of the return spring 61 is provided with a hook 62, and the hook 62 is detachably hooked into the hook hole 321 provided on the head of the knife handle II 32.

[0055] Such as Figure 14 As shown, in the prior art, the worker applies pressure and thrust to the hand saw 16 during the reciprocating sawing process of the hand saw, which prompts the hand saw 16 to reciprocate back and forth. It is not difficult to see that the worker can only exert force on one side of the branch 13 during sawing. , The cutting efficiency is low.

[0056] The design concept of this patent is that one is to combine the pruning shear...

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 ...
