Abstract

The utility model provides a pair of insulating scissors for pruning high fruit tree branches located below an electric wire. The pair of insulating scissors is characterized by comprising a scissor head, an insulating rod, an insulating stay wire and a tension sleeve, wherein the scissor head is composed of a movable scissor blade and a fixed scissor blade, the middle portions of the movable scissor blade and the fixed scissor blade are hinged to each other, the handle portion of the fixed scissor blade is fixedly connected with the insulating rod, the end of handle portion of the movable scissor blade is connected with the insulating stay wire, and a torsion spring is arranged between the movable scissor blade and the fixed scissor blade. When the pair of insulating scissors is used for pruning the high fruit tree branches located below the electric wire, the fixed scissor blade of the insulating scissors is aligned with the trunk portion of the branches and inserted into the trunk portion, the tension sleeve is pulled, the tension sleeve drives the movable scissor blade to move through the insulating stay wire, the branches needing pruning are easily pruned, and the scissor head recovers to the open state after the tension sleeve is released. The portions, in contact with a human body, of the pair of insulating scissors are all made of insulating materials, so that use is safe and reliable; due to the fact that the scissor head and the tension sleeve are used in cooperation with each other, the high branches needing pruning can be pruned accurately and easily; on the premise that the safety of the electric wire is guaranteed, large damage to a fruit tree is avoided, and line maintenance cost is reduced.

Description

A kind of insulation cutter of pruning fruit tree branches of tall trees under power line
Technical field
The utility model relates to a kind of tree pruning tool, particularly prunes the insulation cutter of fruit tree branches of tall trees under power line.
Background technology
Trees under transmission line of electricity need often to prune, to prevent that tall trees branch from affecting the normal trend of transmission line of electricity.In flat-bottomed land, the trees under power circuit are divided into timber and set two kinds with tree and fruit tree, and due to the attribute difference of seeds, the mode of pruning is also different.For seeds such as the trees such as willow, Chinese parasol tree, easily consult felling, the operating type that can adopt pull bar to coordinate with chain saw is pruned.But should not adopt aforesaid way for all kinds of fruit tree trees, because fruit tree tree is the major source of revenues of the annual economy of orchard worker, if excessively prune bring larger economic loss to orchard worker, increase line upkeep cost simultaneously.Therefore, need to be a kind of with insulation cutter insulation function, that can carry out to fruit tree branches of tall trees fine pruning, prune problem to solve fruit tree under power line.
Utility model content
The purpose of this utility model is the drawback for prior art, and the insulation cutter of fruit tree branches of tall trees under a kind of simple in structure, pruning power line of using safety, flexible operation is provided.
Problem described in the utility model realizes with following technical proposals:
A kind of insulation cutter of pruning fruit tree branches of tall trees under power line, special feature is, it comprises haircut, insulating bar, insulation bracing wire, pulling force sleeve, described haircut is made up of movable snip and fixing snip, the middle part of movable snip, fixing snip is hinged, the affixed insulating bar of shank of fixing snip, the shank termination of movable snip connects insulation bracing wire, between movable snip and fixing snip, is provided with torsion spring.
The insulation cutter of fruit tree branches of tall trees under above-mentioned pruning power line, the middle part of described insulating bar is provided with slide bar section, slide bar section outside suit pulling force sleeve, pulling force sleeve and slide bar section are slidably matched, and insulation bracing wire connects pulling force sleeve; Be respectively equipped with only cover and lower only cover at slide bar section upper and lower end, between upper only cover and pulling force sleeve, be connected by return spring.
The insulation cutter of fruit tree branches of tall trees under above-mentioned pruning power line, the inwall place on described insulating bar top is provided with insulation bracing wire spacing ring.
The insulation cutter of fruit tree branches of tall trees under above-mentioned pruning power line, the bottom of described insulating bar is provided with lower jacket.
The utility model for fruit tree high branch trimming Design of Problems under power line a kind of insulation cutter.Described insulation cutter comprises haircut, insulating bar, insulation bracing wire, pulling force sleeve etc., the space, limb position of the fixing snip of insulation cutter being aimed to branch in the time pruning upper branch of fruit trees under power line embeds, afterwards, pull pulling force sleeve, pulling force sleeve moves and passes through insulation bracing wire drive activity snip and move, easily cut off the branch limb that needs pruning, after pruning, loosening pulling force sleeve, pulling force sleeve is under the active force of return spring and torsion spring, make haircut recover the open state before pruning, just can carry out operation next time.The utility model and human body contact site all adopt insulating materials, safe and reliable, being used in conjunction with of haircut and pulling force sleeve can be pruned branches of tall trees by wish accurately and easily be cut, ensureing under the prerequisite of power circuit safety, avoid fruit tree to produce larger damage, reduced line upkeep cost.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure, each list of reference numerals is: 1, fixing snip, 2, torsion spring, 3, movable snip, 4, insulation bracing wire, 5, insulating bar, 6, insulation bracing wire spacing ring, 7, upper only cover, 8, return spring, 9, pulling force sleeve, 10, slide bar section, 11, lower only cover, 12, lower jacket.
Embodiment
Referring to Fig. 1, the utility model comprises haircut, insulating bar, insulation bracing wire, pulling force sleeve.Described haircut is made up of movable snip 3, fixing snip 1, the middle part of movable snip, fixing snip is hinged, between movable snip and fixing snip, be provided with torsion spring 2, under the effect of torsion spring elastic force, movable snip and fixing snip are conventionally in illustrated open state, so that the branch that pruning trees upwards grows.The affixed insulating bar 5 of shank of fixing snip, the shank termination of movable snip connects one end of insulation bracing wire 4.Described insulating bar, insulation bracing wire, pulling force sleeve all adopt the good material of insulating properties to make.
Still, referring to Fig. 1, the middle part of insulating bar 5 is provided with slide bar section 10, slide bar section outside suit pulling force sleeve 9, and pulling force sleeve can slide up and down along slide bar section, the affixed pulling force sleeve of the insulation bracing wire other end.On slide bar section upper and lower end is fixing respectively, only overlap 7 and only overlap 11 down, upper only cover and lower only cover are for the sports limiting to pulling force sleeve.Between upper only cover and pulling force sleeve, be connected by return spring 8.Be provided with insulation bracing wire spacing ring 6 at the inwall place on insulating bar 5 tops.Be provided with lower jacket 12 in the bottom of insulating bar 5.
Still referring to Fig. 1, when the utility model uses, the fixing snip of haircut 1 is aimed to space, the limb position insertion for the treatment of pollard, pull pulling sleeve cylinder 9 downwards, pulling force sleeve overcomes spring force and drives insulation bracing wire campaign, the action of insulation bracing wire drive activity snip, movable snip is involutory by active force and the fixing snip of lever, easily cut off the branch limb that needs pruning, after this operation completes, loosening pulling force sleeve, under the acting in conjunction of return spring 8 and torsion spring 2, make movable snip recover the open state before pruning, just can carry out cut operation next time.
