branch pruning tool

technical field

The utility model relates to a tool for maintaining and overhauling overhead power lines, in particular to a tree branch pruning tool. the

Background technique

In the maintenance and overhaul operation of overhead power lines, it is often necessary to trim trees close to the power lines to ensure the safe operation of the power lines. Traditional high-altitude tree branch pruning is completed by maintenance personnel climbing trees, which is not only time-consuming and laborious, but also poses a greater safety risk. the

In addition, traditional tree branch pruning tools are generally machetes, scissors, saws, etc. These tools are of high quality, and it will be laborious for maintenance personnel to hold such tools for a long time, and the branches are of different sizes. When removing larger branches, It cannot be replaced by scissors, it needs to be replaced by machete or saw blade, and it is very inconvenient and unsafe to replace tools at high altitude. the

Utility model content

The technical problem to be solved by the utility model is that: aiming at the above-mentioned problems existing in the prior art, the utility model provides a branch pruning tool with simple structure, convenient use and labor saving. One piece, there is no need to change tools when working at heights; and it also has a retractable bracket to support the scissors, which saves time and effort without the need for maintenance personnel to lift it up during use. the

In order to achieve the above object, the branch pruning tool of the present utility model includes scissors, a base and a support, the above-mentioned support is fixed on the base, the above-mentioned scissors are connected to the upper end of the support through a hinge shaft, the back of the above-mentioned scissors is provided with sawtooth, and the above-mentioned support is telescopic pole. In this solution, on the one hand, the back of the scissors is equipped with serrations, which is equivalent to a saw blade, so that the branch pruning tool integrates the functions of scissors and saw blades, and there is no need to replace tools when working at heights; on the other hand, the scissors pass through the base And the bracket is supported on the bottom surface. The height of the scissors can be adjusted by the telescopic bracket, and the position of the scissors can be adjusted by the hinge shaft. When the maintenance personnel use it, they don’t need to lift the tool forcefully. They only need to hold the handle of the scissors to cut the branches. Or just saw it, and it is very labor-saving to use; in addition, the knife has a simple structure, is easy to disassemble, and is easy to carry. the

As a further improvement of the present utility model, the above-mentioned branch pruning tool also includes a protective shell arranged outside the sawtooth, and the two ends of the above-mentioned protective shell are respectively fixed on the scissors by two bolts. When the branch pruning tool is not in use, close the cutting edge of the scissors, and fix the protective shell on the scissors, so that the sawtooth is wrapped in the protective shell to prevent it from accidentally injuring maintenance personnel; when in use, unscrew the bolt and take off the protective shell to use. the

In order to fully protect the safety and prevent accidental injury of maintenance personnel by the sawtooth, and comprehensively consider the cost of the tool, as a preference, the length of the above-mentioned protective shell is the same as that of the sawtooth. the

Further, the above-mentioned scissors include two scissor blades and two insulating handles. the

Preferably, the scissor blades are made of stainless steel or high carbon steel. the

In order to further keep the blades and serrations of the scissors sharp for a long time, and have greater pressure and friction bearing capacity, as a preference, the scissors are made of high carbon steel with a grade of CW6Mo5Cr4V2. the

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. The back of the scissors of the present invention is provided with sawtooth, which integrates the functions of scissors and saw blades. It is not necessary to change tools when working at high altitudes, which is convenient to use and can prevent the danger caused by changing tools at high altitudes;

2. The scissors of the present invention are supported on the bottom surface by the base and the bracket. The height of the scissors can be adjusted by the telescopic bracket, and the position of the scissors can be adjusted by the hinge shaft. When the maintenance personnel use it, it is not necessary to lift the tool forcefully, which is convenient and labor-saving;

3. The utility model is simple in structure, easy to disassemble and easy to carry.

Detailed ways

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto. the

[Example 1]

As shown in Figure 1, the branch pruning tool of the present embodiment comprises scissors 3, base 1 and support 2, wherein: above-mentioned support 2 is telescopic rod, is fixed on the base 1, and above-mentioned scissors 3 is connected on support 2 upper ends by hinge shaft 4 , the height of the scissors 3 can be adjusted by the support 2, and the specific position of the scissors 3 can be adjusted by the hinge shaft 4; the back of the above-mentioned scissors 3 is provided with serrations 311, so that the back of the scissors 3 forms a saw blade. In practical applications, the sawtooth 311 and the back of the scissors 3 can be integrally formed, that is, the back of the scissors 3 can be directly cast into a zigzag shape; .

【Example 2】

As shown in Figure 2, on the basis of Embodiment 1, the branch pruning tool in this embodiment also includes a protective shell 5 arranged outside the sawtooth 311 to prevent the sawtooth 311 from accidentally injuring maintenance personnel, and the length of the protective shell 5 is the same as that of the sawtooth 311 , both ends are respectively fixed on the scissors 3 by two bolts 6 .

The above-mentioned scissors 3 include two scissors 31 and two insulating handles 32, and the scissors 31 are made of stainless steel or high-carbon steel whose grade is CW6Mo5Cr4V2. The high carbon steel of CW6Mo5Cr4V2 has high hardness, good wear resistance, certain strength and toughness, which can keep the knife edge and saw edge of the branch pruning tool sharp for a long time, and it can withstand considerable pressure and friction. However, it still maintains its shape and size. the

The above are only preferred implementations of the utility model, and the scope of protection of the utility model is not limited to the above-mentioned embodiments, and all technical solutions under the thinking of the utility model all belong to the scope of protection of the utility model.
