Abstract

The utility model discloses a tree trimming saw which is characterized in that a trimming saw body is a section of circular arc shape; saw teeth are arranged on the inner arc side of the circular arc section; curvature radius of a circular arc formed by the tips of the saw teeth is 200 to 400 mm; a connection section is connected to one end of the saw body in the tangential direction and used for connecting with a long handle, or a rod-shaped handle is directly connected to one end of the saw body in the tangential direction. The tree trimming saw has the advantages of safety, saving labor and high efficiency, when the trimming saw is used for trimming branches.

Description

The trees trim saw

Technical field

The utility model relates to a kind of to the prune instrument of usefulness of trees.

Background technology

Fruit tree is pruned in necessary for growth, and to mould shape of tree-crown, same ornamental trees and shrubs etc. also need to prune, and remove unwanted branch.For thicker branch, at present a kind of is to adopt the scoop that has long handle to root out, and another kind of mode is to adopt double ladder or go up tree and go up with the handsaw saw and remove or cut down with cutter.Adopt and need carry out ascend operation with handsaw with the mode that cutter is cut, dangerous and only be applicable to the pruning of the branch of tree crown middle and lower part; Though and can avoid the inconvenience of ascend operation with the scoop of belt length handle shovel, but owing to be to exert oneself from bottom to top, and because the deadweight of stock and metal scoop head, operate and not only make operating personnel tired easily more painstakingly, and be difficult to the accurately accuracy of control shovel each drop point, therefore also make operating efficiency very low.

The utility model content

The purpose of this utility model is to provide a kind of trees trim saw, utilizes this trim saw to carry out the pruning of trees, and is safe, laborsaving.

The utility model adopts following technical scheme: a kind of trees trim saw, saw is as one section circular arc, its sawtooth is arranged on inner arc one side of this arc section, the radius of curvature of sawtooth circular arc that increment forms is 200-400mm, is connected with in the tangential direction of sawing body one end to be used for the linkage section that links to each other with long handle or directly to be connected with shaft-like handle.

This trees trim saw of the present utility model, adopting radius of curvature is the circular arc saw body of 200-400mm, the branch that can not need ascend operation directly to face eminence from ground behind the long handle is installed to be pruned, and owing to adopt arc saw body to make that with respect to the rip body application point of sawtooth one side and branch is the middle and upper part that is positioned at the branch that is roughly circular cross-section, bigger than rip body to the high contact-making surface of application point of branch, by choose reasonable to radius of curvature, make the application of force more reasonable, by push-and-pull can be sawed-off with branch fast back and forth, has safety, laborsaving, the characteristics that efficient is high.

Description of drawings

Fig. 1 is the schematic diagram of a kind of trees trim saw of the present utility model.

Fig. 2 is the another kind of embodiment schematic diagram of trees trim saw of the present utility model.

Fig. 3 is a trees trim saw occupation mode schematic diagram of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, to help understanding content of the present utility model.

As depicted in figs. 1 and 2, the steel saw body 1 of trees trim saw is one section circular arc, its sawtooth 3 is arranged on inner arc one side of this arc section, the radius of curvature R of sawtooth circular arc that increment forms (among the figure shown in the dotted line) is 200-400mm, is connected with in the tangential direction of saw body one end to be used for the linkage section 2 that links to each other with long handle.Linkage section 2 can be illustrated in figure 1 as a cylindrical section, is used for inserting easily the long handle that long rod or bamboo bar are made, to connect.Linkage section 2 also can be illustrated in figure 2 as one section metallic plate, on the metallic plate installing hole is being set so that be installed on the long handle with nail or screw.Certainly the saw body also can directly link to each other with segment length's handle.

For avoiding binding, sawtooth can adopt left and the arrangement mode of inclination that interlocks to the right.

As shown in Figure 3, adopt the arc saw body of this radius of curvature, when long handle is same inclination angle, compare with the rip body that is indicated with dotted line A, its application point to branch 5 is positioned at the branch middle and upper part, than rip body more near the top of branch, more effectively in will sawing body incision branch, through overtesting, can more laborsaving and sawed-off fast branch under this radius of curvature, improve the efficient of pruning, and safer, can prune the branch at tree crown bottom and top easily and safely, be particularly suitable for the pruning of fruit tree.Radius of curvature is excessive, and the saw body is unfavorable for eating saw for a short time to the pressure of branch, and radius of curvature is too small, and the saw body is hooked in and makes the saw body be difficult to again be spurred back and forth on the branch, is not easy to equally operate and influences operating efficiency.

Claims

1. trees trim saw, it is characterized in that: saw is as one section circular arc, its sawtooth is arranged on inner arc one side of this arc section, the radius of curvature of sawtooth circular arc that increment forms is 200-400mm, is connected with in the tangential direction of sawing body one end to be used for the linkage section that links to each other with long handle or directly to be connected with shaft-like handle.

2. trees trim saw as claimed in claim 1 is characterized in that: described sawtooth adopts left and the arrangement mode of inclination that interlocks to the right.

3. trees trim saw as claimed in claim 1 or 2 is characterized in that: described linkage section is a cylindrical section.
