Description

A high-altitude branch pruning saw

technical field

The utility model relates to a high-altitude branch pruning saw.

Background technique

With the development of society, people pay more and more attention to urban afforestation; due to the continuous increase of trees, the subsequent afforestation work is also becoming more and more tense. At present, there are many kinds of high-altitude branch shears on the market, in different forms, with scissors in the majority, manual and electric. What use saw blade is seldom, CN101536650A discloses a kind of high-altitude shear, has utilized scissors and sawtooth, has realized the function of pruning thick branch and thin branch, but because sawtooth part does not have clamping device, can only prune thick branch. And the trimmer has a complicated structure and is expensive. Therefore be necessary to develop a kind of simple in structure, be suitable for the high-altitude pruning saw that popularizes.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a high-altitude branch pruning saw, which has the characteristics of simple structure, strong practicability and simple operation.

In order to achieve the above object, the technical solution adopted by the utility model is:

A high-altitude tree branch pruning saw, comprising a hollow support rod 1, the top of the hollow support rod 1 is welded to the bottom end of a cutter head 2, a slot 201 and a slideway 202 are arranged on the side of the cutter head 2, and a saw blade 5 and a saw blade are installed in the slot 201. 5 is connected to the pin 301 arranged in the slideway 202, the pulley 3 is connected to the top of the cutter head 2 through a hinge, and the rope goes around the pulley 3 to connect with the saw blade 5; the upper part of the hollow support rod 1 is fixed with a fixed piece 6, which is simultaneously The first spring 302 is connected to the saw blade 5, the movable scissors 4 are hinged to the lower part of the cutter head 2, and the pull rod 303 in the hollow support rod 1 is connected to the hand pliers 7 arranged at the lower part of the hollow support rod 1, and the hand pliers 7 control the movement The scissors 4 clamp the branch.

The pliers 7 are composed of an upper handle 701 and a lower handle 702 hinged, and a second spring 304 is arranged between the upper handle 701 and the lower handle 702 of the pliers 7 .

Compared with the prior art, the utility model has the characteristics of simple structure, strong practicability and convenient operation; when using the utility model to prune branches, laborers do not need to climb to the tree to prune, which greatly reduces the labor intensity of workers, At the same time, there is no potential safety hazard for workers falling from a high altitude. Moreover, the cutter has an automatic retraction function during the use of the utility model, which saves more labor. And the active scissors are added to make up for the shortcomings of traditional pruning saws that cannot clamp branches.

Detailed ways

The implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and examples.

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a high-altitude branch pruning saw includes a hollow support rod 1, the top of the hollow support rod 1 is welded to the bottom end of the cutter head 2, and the side of the cutter head 2 is provided with a slot 201 and Slideway 202, saw blade 5 is installed in draw-in groove 201, and saw blade 5 is connected with the pin 301 that is arranged in slideway 202, and saw blade 5 can slide back and forth in slideway 202, and pulley 3 is connected on the top of cutter head 2 by hinge , the rope goes around the pulley 3 and is connected with the saw blade 5, and power is provided by pulling the rope. A fixed piece 6 is fixed on the upper part of the hollow support rod 1 , and the fixed piece 6 is connected with the saw blade 5 through the first spring 302 at the same time, so that the saw blade 5 reciprocates in the slideway 202 . The movable scissors 4 are hinged at the bottom of the cutter head 2, and are connected to the hand pliers 7 arranged at the bottom of the hollow support bar 1 through the pull rod 303 in the hollow support bar 1. The hand pliers 7 are composed of an upper handle 701 and a lower handle 702. The hand pliers A second spring 304 is arranged between the upper handle 701 and the lower handle 702 of 7 . The hand pliers 7 control the movable scissors 4 to open and close to clamp the branches, so that the trimmer plays a role in supporting and clamping when pruning small branches, and the pruning of thick branches can also be done without clamping.
