Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0011] In the two embodiments of the present invention as shown in the figure, the tree is first clamped from both sides by the fixed saw blade 1 and the adjustable saw blade 3, and the saw teeth will have multiple cuts into the tree body, and then the handle 2 is parallel to the sawing plane. Pull or push in the direction of the fixed saw blade 1 and adjust the saw teeth of the saw blade 3 to gradually cut out a circle of deep grooves on the periphery of the tree. Because the handle is used to carry out the action of boarding or pushing, the principle of leverage is fully utilized, so that the operator will be relatively relaxed and not very laborious. Use this utility to carry out sawing trees, should step by step, after cutting out a circle, tighten up some adjusting nuts 5 again, after sawing one layer deeper again, tighten up some adjustin...

Abstract

The invention discloses a manual turning saw, which belongs to the technical field of a manual felling tool and aims at overcoming the defects that the carrying and the use of the existing manual felling tool are inconvenient, the labor is wasted in the operation, the safety is insufficient, and the like. The manual turning saw is provided with a fixed saw blade, wherein one end of the fixed saw blade is connected with a handle, a regulating saw blade is arranged at one side of the fixed saw blade, saw tooth directions of the fixed saw blade and the regulating saw blade are opposite, the center surfaces of the saw blades are positioned on the same plane, screw rods are respectively arranged at two ends of the regulating saw blade, the other ends of the screw rods pass through holes arranged at two ends of the fixed saw blade, and in addition, regulating screw nuts are assembled outside the fixed saw blade. The manual turning saw is applicable to scattered tree sawing.

Description

technical field [0001] The invention relates to a technology of manpower logging tools, in particular to a manpower rotary saw. Background technique [0002] For some planned large-scale timber harvesting in forests and some places specialized in wood processing, electrified and mechanized equipment and tools can be used for sawing wood processing by taking advantage of their own scale. However, for some small amount of sporadic logging and some logging operations under special circumstances, such as: farmers cut a small number of trees on the private mountain with the approval of the relevant management department; the departments of electricity, transportation, and exploration need to carry out sporadic tree logging during the construction process. felling; and forestry managers have to deal with some diseased trees, dead trees, and special-shaped trees, etc. Due to these logging tasks, the workload is not large, there are not many people, and many times there are many un...
