Abstract

Portable high-altitude branch scissors are suitable for branch pruning in railway, electric power, gardening and other departments. The fixed blade is composed of a circular arc part and a straight part. The straight part can easily guide the branches into the cutting part; the blade curve of the rotating knife is an equihelical line, which ensures that the shearing force is uniform during the cutting process and gradually integrates with the fixed blade. The blade meshes; the spring ensures the automatic reset of the rotating knife; the steel wire rope passes through the movable pulley and the fixed pulley to reduce the tension during operation, and improve the stress condition of the high-altitude branch scissors and reduce the bending of the long pole.

Description

Portable high-altitude branch scissors

Technical field:

The utility model belongs to a special pruning tool for railway, electric power, gardening and other departments, in particular to a high-altitude tree branch scissors for improving the efficiency of tall tree pruning, reducing the labor intensity of workers and eliminating the danger of the working environment.

Background technique:

Gardens, orchards, and departments such as electrified railways and power supplies often need to prune branches. At present, under normal circumstances, workers climb to the tree to prune the branches. The work efficiency is low, and there are dangers such as injury and disability of the operator.

Invention content:

The purpose of this utility model is to overcome above-mentioned deficiencies in the prior art, provide a kind of use safe, convenient, high-efficiency portable high-altitude branch scissors, guarantee the efficiency of pruning work and the personal safety of operators.

The utility model is realized in the following ways:

Portable high-altitude tree branch scissors, including a bracket, a spring, and a long pole, are characterized in that: it also includes a fixed knife, a rotating knife, a movable pulley, a fixed pulley, and a wire rope; the fixed knife is connected with the bracket as a whole, and the rotating knife is hinged with the fixed knife and the bracket The spring connects the top of the fixed knife and the end of the rotating knife; two fixed pulleys are installed at the lower end of the bracket, and a movable pulley is installed at the end of the rotating knife, and the wire rope goes around the movable pulley and the fixed pulley; the telescopic long rod is fixed at the lower end of the bracket. The utility model is also characterized in that: the blade of the fixed knife is composed of an arc part and a straight line; the blade curve of the rotating knife is an equihelical line, which ensures that the shearing force is uniform during the shearing process and gradually engages with the fixed blade.

The utility model has a novel structure and can ensure that the branch pruning work is convenient, labor-saving and efficient. The spring can ensure that the rotating knife resets automatically when the cutting is completed; the wire rope bypasses the two fixed pulleys and the movable pulley to reduce the tension during cutting, improve the force of the scissors, and reduce the bending of the long rod; the telescopic long rod can be adjusted according to different Adjustable length for working conditions. Using this equipment can save a lot of manpower and material resources.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Among the figure, 1 is a fixed knife, 2 is a rotating knife, 3 is a support, 4 is a spring, 5 is a movable pulley, 6 is a fixed pulley, 7 is a long rod, and 8 is a wire rope.

Detailed ways:

Provide a best embodiment of the present utility model below in conjunction with accompanying drawing.

Portable high-altitude branch scissors, the fixed knife 1 and the bracket 3 are welded as one, and the rotating knife 2 is hinged with the fixed knife 1 and the bracket 3; the blade curve of the fixed knife 1 is composed of a R20mm arc and a straight line, and the straight line can be conveniently Lead the branches into the cutting area; the blade curve of the rotating knife 2 is an equihelical line to ensure that the shearing force is uniform during the cutting process, and gradually meshes with the fixed knife 1; the spring 4 connects the top of the fixed knife 1 and the rotating knife 2 end, to ensure that the rotating knife 2 automatically resets after cutting; the lower end of the bracket 3 is equipped with two fixed pulleys 6, and the end of the rotating knife 2 is equipped with a movable pulley 5, and the steel wire rope 8 can reduce the pulling force during operation through the movable pulley 5 and the fixed pulley 6 ; The telescopic pole 6 is fixed on the lower end of the bracket 3, and the longest can reach 10 meters.

The test results show that the new portable high-altitude branch scissors can cut branches within a height range of 10 meters and a maximum diameter of 40 mm. It is flexible, convenient and light in use. The working height can be conveniently controlled by long pole and wire rope.
