Abstract

The utility model discloses a branch pruning implement, which comprises a pair of scissors (3), a base (1) and a holder (2), wherein the holder (2) is fixed on the base (1), the scissors (3) are connected with the upper end of the holder (2) through a hinged shaft (4) , the back of one scissor blade of the scissors is provided with sawteeth (311), and the holder (2) is a telescopic rod. The branch pruning implement integrates functions of the scissors and functions of a saw together, so implements do not need to be replaced during the high altitude working, and the branch pruning implement is convenient to use. Moreover, when in use, the branch pruning implement does not need to be lifted by hands of maintainers with labor, and is time-saving and labor-saving. According to the branch pruning implement disclosed by the utility model, the problems in the prior art that the implements are inconvenient and unsafe to replace in the high altitude branch pruning and large strength is consumed when the maintainers lift the branch pruning implement for a long time are solved, and the branch pruning implement has the advantages of simple structure, convenience in use, labor saving and the like.

Description

Tree branch pruning tool

Technical field

The utility model relates to overhead power line to be safeguarded and maintenance instrument, is specifically related to a kind of tree branch pruning tool.

Background technology

In the maintenance and upkeep operation of overhead power line, often need to prune the trees near power circuit, to guarantee the security of operation of power circuit.Traditional pruning high-altitude branches completes by maintainer's operation of climbing the tree, and not only wastes time and energy, and also has larger security risk.

In addition, traditional tree branch pruning tool is generally chopper, scissors, saw cutter etc., this class instrument quality is larger, maintainer holds for a long time such instrument and can relatively require great effort, and branch is not of uniform size, when rejecting larger branch, adopt scissors to change into, need to be replaced with chopper or saw cutter, and high-altitude replacing instrument is very inconvenient and dangerous.

Utility model content

The technical problems to be solved in the utility model is just: the problems referred to above that exist for prior art, the utility model provides a kind of simple in structure, easy to use, labour-saving tree branch pruning tool, this tree branch pruning tool integrate scissors and saw cutter function, during work high above the ground without replacing instrument; And it also has telescopic stent support scissors, during use, without maintainer, lifts, time saving and energy saving.

For achieving the above object, tree branch pruning tool of the present utility model, comprises scissors, base and support, and above-mentioned support is fixed on base, and above-mentioned scissors in support upper end, is provided with sawtooth on the knife back of above-mentioned scissors by stud connection, and above-mentioned support is expansion link.In this programme, on the one hand, on the knife back of scissors, be provided with sawtooth, be equivalent to a saw cutter, make this tree branch pruning tool integrate scissors and saw cutter function, during work high above the ground without replacing instrument; On the other hand, scissors by base and stent support on bottom surface, the height of scissors can regulate by telescoping shoring column, the position of scissors can regulate by hinge, when maintainer uses, without firmly lifting cutter, its needs are held scissors handle branch are sheared or dragsaw, use very laborsaving; In addition, this cutter structure simply, easily dismantle, be easy to carry.

As further improvement of the utility model, above-mentioned tree branch pruning tool also comprises the containment vessel that is arranged on sawtooth outside, and above-mentioned containment vessel two ends are respectively bolted on scissors by two.Tree branch pruning tool, when not using, closes up the edge of a knife of scissors, and containment vessel is fixed on scissors, and sawtooth is wrapped in containment vessel, prevents its accidental injury maintainer; During use, turn on bolt and take off containment vessel and can use.

For fully carrying out security protection, when preventing that sawtooth from accidentally injuring maintainer, consider the cost of charp tool, as preferably, above-mentioned containment vessel is identical with sawtooth length.

Further, above-mentioned scissors comprises two shear blades and two insulated handles.

Preferably, above-mentioned shear blade consists of stainless steel or high-carbon steel.

In order further to make, the edge of a knife of scissors and sawtooth are long-term keeps sharp, has larger pressure and frictional force ability to bear, and as preferably, the high-carbon steel that above-mentioned shear blade is CW6Mo5Cr4V2 by the trade mark forms.

With respect to prior art, the utlity model has following advantage and beneficial effect:

1, on the knife back of scissors of the present utility model, be provided with sawtooth, integrate the function of scissors and saw cutter, without replacing instrument, easy to use during work high above the ground, and can prevent the danger that high-altitude replacing instrument brings;

2, scissors of the present utility model is by base and stent support on bottom surface, and the height of scissors can regulate by telescoping shoring column, and the position of scissors can regulate by hinge, when maintainer uses, without firmly mentioning cutter, easy to use laborsaving;

3, the utility model dismounting simple in structure, easy, be easy to carry.

Embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.

[embodiment 1]

As shown in Figure 1, the tree branch pruning tool of the present embodiment comprises scissors 3, base 1 and support 2, wherein: above-mentioned support 2 is expansion link, be fixed on base 1, above-mentioned scissors 3 is connected to support 2 upper ends by hinge 4, the height of scissors 3 can be adjusted by support 2, and the particular location of scissors 3 can be adjusted by hinge 4; On the knife back of above-mentioned scissors 3, be provided with sawtooth 311, make the knife back of scissors 3 form a saw cutter.In practical application, sawtooth 311 can be an integrated integral body with the knife back of scissors 3, directly the knife back of scissors 3 is cast to zigzag; Sawtooth 311 can be also that this saw blade is fixed on the knife back of scissors 3 by the sawtooth of a saw blade.

[embodiment 2]

As shown in Figure 2; on the basis of embodiment 1, the tree branch pruning tool in the present embodiment also comprises the containment vessel 5 that is arranged on sawtooth 311 outsides, prevents sawtooth 311 accidental injury maintainers; these containment vessel 5 length are identical with sawtooth 311, and two ends are respectively fixed on scissors 3 by two bolts 6.

Above-mentioned scissors 3 comprises two shear blades 31 and two insulated handles 32, and the high-carbon steel that shear blade 31 is CW6Mo5Cr4V2 by stainless steel or the trade mark forms.The high-carbon steel of CW6Mo5Cr4V2 has higher hardness, good wearability, certain intensity and toughness, can make the edge of a knife and the saw kerf of this tree branch pruning tool keep over a long time sharp, bearing under the condition of sizable pressure and frictional force, still can keep its shape and size constant.

Below be only preferred embodiment of the present utility model, protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, the some improvements and modifications not departing under the utility model principle prerequisite, should be considered as protection domain of the present utility model.
