Gardening-purpose high branch shearing device

Abstract

The invention discloses a gardening-purpose high branch shearing device, and belongs to high branch shearing devices in the technical field of gardening tools. The purpose of the invention is to provide a gardening-purpose high branch shearing device capable of realizing automatic reset. The technical scheme of the gardening-purpose high branch shearing device is as follows: the gardening-purposehigh branch shearing device comprises a hand-held long pole, a scissor handle, a first movable blade, a second movable blade, and a pull rope; the scissor handle is connected to a top part of the hand-held long pole; the first movable blade and the second movable blade are both hinged to the scissor handle; a swing rod is hinged with the scissor handle; a connecting rod is hinged to a tail part ofthe first movable blade, and is hinged with the swing rod; a containing cavity is formed in the swing rod, and is divided into a shaft containing chamber and a spring containing chamber; a compression spring is arranged inside the spring containing chamber; one end of the compression spring makes contact with a clapboard; the other end of the compression spring is provided with a rope head fixingseat; a pin shaft is connected with a reset rope; and the reset rope sequentially penetrates through the shaft containing chamber, the clapboard and the spring, and is connected with the rope head fixing seat. The gardening-purpose high branch shearing device is a high branch shearing device applicable to branch pruning.

Description

technical field [0001] The invention belongs to the technical field of gardening tools, and relates to a gardening tall branch shearing device. Background technique [0002] High-branch shears are a commonly used gardening pruning tool, mainly for cutting off high-altitude branches of small trees. There are simple types of high-branch shears, and the product quality is poor. Common faults: clipping, not opening the mouth, falling screws, short springs, and no pulleys. Most of the poles are made of local materials such as wooden poles and bamboo poles. Features of some high-end high-branch shears: hand-pinch high-branch shears, branch shears, and guillotine type. The rods are mostly fiberglass rods and iron rods, and the lengths are: 3 meters, 3.5 meters, 4 meters, and 5 meters. According to the type of use, there are also special high-branch shears for professional use in the electrical industry. Effects: 1. It plays a great role in preventing and controlling the America...

AI Technical Summary

Problems solved by technology

When the high branch shears are interspersed between the branches to prune the branches, since the branches are staggered, the return spring is very easily restricted by the branches during pruning and cannot be stretched, compressed or reset after the pruning is completed. The spring is easily restricted by the branches and cannot be reset, so the blade cannot be reset normally, which affects the pruning efficiency of the branches
