JP3048664U - Double edge pruning saw - Google Patents

Abstract

(57) [Summary] [PROBLEMS] The present invention makes it possible to cut a tree from the top and bottom of a tree easily in pruning work without holding a saw, thereby streamlining pruning work and eliminating the danger of working at heights. The object is to obtain a pruning saw. SOLUTION: A blade plate having a double-edged tooth row extending at a predetermined angle is attached to a direction in which a side shape becomes a front portion of a saw blade which is curved upwardly gently over the entire length, and a lower saw of the blade plate is attached. The blade is a tooth row of a large blade, and the upper saw blade is provided with a short tooth row of a small blade at an appropriate position above the blade plate, and a guide portion without a blade is provided in front of the tooth row.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a double-edged pruning saw used for pruning above and below tree branches.

[0002]

[Prior art]

 Conventionally, when a tree is likely to crack while cutting from the upper side of the branch by pruning, the cutting was performed from the lower side of the branch, and the one-sided pruning saw held upside down to cut.

[0003]

[Problems to be solved by the invention]

 In pruning trees, cracks may occur due to the weight of the branches while cutting from the upper side of the branches, and cuts were made from the upper and lower sides so that the branches were not broken by making a cut from the lower side of the branches. In the work, there was only a single-edged pruning saw, and the upside down of the saw was held upside down.However, in the work, the angle of the saw pattern was different and it was difficult to grasp the tree, and it was difficult to pruning trees. There was also the danger of switching during work.

An object of the present invention is to provide a double-edged pruning saw that can easily perform cutting from above and below branches in a tree pruning operation without changing a saw, rationalize the pruning operation and eliminate danger in high-altitude operation. And

[0005]

[Means for Solving the Problems]

 A blade plate having a double-toothed tooth row extending at a predetermined angle is attached in a direction in which the side shape becomes the front part of a saw blade that is curved gently upward over the entire length, and the lower blade of the blade plate is large. The upper saw blade is provided with a means for providing a short blade tooth line at an appropriate position above the blade plate.

[0006]

[Embodiment of the invention]

 With the double-edged pruning saw of the present invention, when used for pruning trees, the upper side of the branch is usually cut with a lower saw blade provided on the blade plate, and the branch is likely to crack due to the weight of the branch during cutting. In such a case, a means is provided that allows cutting with the upper saw blade of the blade plate without holding the saw from the lower side, which is the upper cutout portion of the branch.

Further, it is preferable that a saw blade is not provided on a front portion of the upper blade of the blade plate.

[0008]

【Example】

 Next, an embodiment of the invention will be described with reference to the drawings based on an example. In FIG. 1, the front side of the saw pattern 1 has a side shape that is gently curved upward over the entire length and is symmetrical. A blade plate 2 having a double-toothed tooth array extending at a predetermined angle is attached to a part by tightening screws 3 from both sides with a saw blade 1, and a lower saw blade 4 of the blade plate 2 is attached to an upper side of a branch. The upper saw blade 5 is cut so as to lift from the lower side of the branch, so that a small tooth row is provided at an appropriate position above the blade plate 2 in a short position. A guide section 6 without a saw blade is provided in front of the guide section, and the guide section 5 fits into a notch formed by operating the saw back and forth, so that the blade plate can be cut without moving the blade plate from side to side. .

[0009]

[Effect of the invention]

 The present invention is embodied in the form described above and has the following effects.

[0010] By using a pruning saw with two blades, tree branches can be cut freely from above and below without holding the saw, thereby increasing work efficiency and eliminating the danger of holding the saw at high places.

[0011] By providing a guide portion 5 without a saw blade at the front portion of the saw blade 4 at the upper portion of the blade plate, when cutting from the lower side of the unstable branch, the guide portion is guided by the notch of the cut. The part can be fitted and slid and cut straight and neatly.
