Abstract

A pair of convenient high-level branch scissors is applicable for cropping branches for departments of railway, power and gardens and so on, and consists of a stationary blade 1, a rotary blade 2, a support 3, a spring, a movable pulley 5, a fixed pulley 6, a pole 7 and a wire rope 8. The stationary blade edge consists of a circular arc part and a straight part. The straight part can lead branches to the working part of the scissors conveniently. The curve of the edge of the rotary blade is a uniform helix, and ensures uniform shearing force during shearing, and the edge of the rotary is gradually joggled with the edge of the stationary blade. The spring ensures the rotary blade to reset automatically; the wire rope can reduce the pull through the movable pulley and the fixed pulley, improve stress on the high-level branches and the scissors, and reduce bend of the pole.

Description

Portable high-altitude branch scissors
Technical field:
The utility model belongs to a kind of special-purpose pruning tool of departments such as railway, electric power, gardens, and a kind of high-altitude branch of particularly relate to the efficient that is used to improve tall and big tree trimming work, reduce working strength of workers, eliminating working environment danger is cut.
Background technology:
Departments such as gardens, orchard and electric railway, power supply need often branch to be pruned.At present, be to climb to tree by the workman upward branch to be pruned generally speaking, inefficiency, and have danger such as operator's tumble injury disables.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of safe in utilization, convenient, portable high-altitude branch scissors efficiently is provided, and guarantees the efficient of pruning work and operator's personal safety.
The utility model is realized in the following manner:
Portable high-altitude branch scissors comprises support, spring, stock, it is characterized in that: further comprising dead knife, rotating knife, movable pulley, fixed pulley, steel wire rope; Dead knife and support connect as one, and rotating knife and dead knife, support are hinged; Spring is connected and fixed the top of cutter and the end of rotating knife; Two fixed pulleys are equipped with in the support lower end, and the rotating knife end is equipped with movable pulley, and steel wire rope is walked around movable pulley and fixed pulley; Telescopic stock is fixed in the support lower end.Feature of the present utility model also is: the blade of dead knife is made up of circular arc portion and straight line portion; The edge curve of rotating knife guarantees that the shearing force size is even in shear history, and meshes with counteredge gradually for waiting helix.
The utility model novel structure can guarantee that branch pruning work is convenient, laborsaving, efficient.Spring can guarantee to shear that rotating knife automatically resets when finishing; Steel wire rope is walked around two fixed pulleys and movable pulley can reduce pulling force when shearing, and improves the force-bearing situation of scissors, reduces the bending of stock; Telescopic stock can be regulated length according to different working conditions.This equipment of employing can be saved a large amount of human and material resources.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
1 is that dead knife, 2 is that rotating knife, 3 is that support, 4 is that spring, 5 is that movable pulley, 6 is that fixed pulley, 7 is that stock, 8 is a steel wire rope among the figure.
Embodiment:
Provide a most preferred embodiment of the present utility model below in conjunction with accompanying drawing.
Portable high-altitude branch scissors, its dead knife 1 and support 3 are welded as a whole, and rotating knife 2 and dead knife 1, support 3 are hinged; The edge curve of dead knife 1 is by circular arc and one section rectilinear(-al) of one section R20mm, and straight line portion can import the share zone with branch easily; The edge curve of rotating knife 2 guarantees that for waiting helix the shearing force size is even in shear history, and meshes with dead knife 1 gradually; Spring 4 is connected and fixed the top of cutter 1 and the end of rotating knife 2, and assurance is sheared the back rotating knife 2 that finishes and automatically reset; Two fixed pulleys 6 are equipped with in support 3 lower ends, and rotating knife 2 ends are equipped with movable pulley 5, the pulling force when steel wire rope 8 can reduce operation by movable pulley 5 and fixed pulley 6; Telescopic stock 6 is fixed in support 3 lower ends, the longlyest reaches 10 meters.
Test result shows, it is 40 millimeters branch with interior, maximum gauge that this novel portable high-altitude branch scissors can be sheared 10 meters altitude ranges, uses flexibly, convenient, light and handy.Working depth can be easily by stock and steel wire rope control.
