Description

A kind of overhead branch pruning saw
Technical field
The utility model relates to a kind of overhead branch pruning saw.
Background technology
Along with social development, urban afforestation is more and more subject to people's attention; Due to being on the increase of trees, thing followed greening work is also more and more nervous.Occur on the market at present a variety of high-altitude branch shears, form is different, in the majority with scissors, has manual and electronic.Use the little of saw blade, CN101536650A discloses a kind of high altitude scissors, has utilized scissors and sawtooth, has realized the function of pruning fat tree branch and thin branch, but there is no clamping device because of serrated portion, can only prune fat tree branch.And this trimmer complex structure, expensive.Therefore be necessary that exploitation is a kind of simple in structure, be applicable to the high-altitude pruning saw of promoting.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of overhead branch pruning saw, has feature simple in structure, practical and simple to operate.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of overhead branch pruning saw, comprise hollow support rails 1, hollow support rails 1 top and cutter head 2 bottom welding, cutter head 2 sides arrange draw-in groove 201 and slideway 202, the interior installation saw blade 5 of draw-in groove 201, saw blade 5 connects the pin 301 being arranged in slideway 202, and pulley 3 is connected through the hinge on the top of cutter head 2, and rope is walked around pulley 3 and is connected with saw blade 5; Hollow support rails 1 top is fixed with stator 6, stator 6 is connected with saw blade 5 by the first spring 302 simultaneously, movable scissors 4 is articulated with the bottom of cutter head 2, be connected with the hand vice 7 that are arranged on hollow support rails 1 bottom by the pull bar 303 in hollow support rails 1, hand vice 7 are controlled movable scissors 4 and are clamped branch.
Described hand vice 7, by up knob 701 and lower handle 702 hinged composition, are provided with the second spring 304 between the up knob 701 of hand vice 7 and lower handle 702.
Compared with prior art, the utlity model has simple in structure, practical and easy to operate feature; While using the utility model pollard, do not need labourer to climb to and set the pruning of getting on, greatly reduce labourer's labour intensity, there is not the potential safety hazard dropping from high-altitude in labourer simultaneously.And in the utility model use procedure, cutter has automatic retracted function, more laborsaving.And add movable scissors, made up traditional pruning saw and cannot clamp the shortcoming of branch.
