High-sky pruning scissors

Abstract

The invention provides high-sky pruning scissors. The high-sky pruning scissors comprise a handheld part, a connecting part, a shearing part and a driving mechanism, the shearing part comprises a fixed blade and a movable blade hinged to the fixed blade, the driving mechanism is arranged in the handheld part, the connecting part comprises a connecting rod connected between the handheld part and the fixed blade of the shearing part and a pull rod connected to the driving end of the driving mechanism and the movable blade of the shearing part, the connecting rod and the pull rod of the connecting part are both of a length adjustable structure, and by adjusting the length of the connecting rod and the pull rod, the pruning height of the high-sky pruning scissors is adjusted. Weight is distributed on the handheld part, so that the structure is light as a whole, the operation is simple, a distribution power supply line does not need to be lengthened, and electricity is safe; meanwhile, theconnecting rod and the pull rod of the connecting part are both of a length adjustable structure, and then by adjusting the length of the connecting rod and the pull rod, the pruning height of the high-sky pruning scissors is adjusted.

Description

technical field [0001] The invention relates to the field of pruning shears, in particular to high-altitude pruning shears which are portable, simple and safe to operate, and can adjust the pruning height. Background technique [0002] In order to regulate the growth and results of fruit trees, fruit farmers often need to prune fruit trees. For taller fruit trees, most of the existing pruning shears are manual, and the steel wire rope connected to the handle pulls the scissors for pruning, which is time-consuming and laborious. Existing pruning shears are because too long in addition, although some have adopted the structure of telescopic rod, just reduced the length of pruning shears to a certain extent, carry still inconvenient. [0003] Electric pruning shears use electric motors as power, saving time and effort, but it is more difficult for electric scissors on the market to prune higher branches. Such as the Chinese Utility Model Publication Patent Application No. CN2...

Problems solved by technology

For taller fruit trees, the existing pruning shears are mostly manual, and the steel wire rope connected to the handle pulls the scissors for pruning, which is time-consuming and laborious.

In addition, because the existing pruning shears are too long, although some have adopted the structure of the telescopic rod, the length of the pruning shears has only been reduced to a certain extent, and it is still inconvenient to carry.

[0003] Electric pruning shears are powered by electric motors, saving time and effort, but the electric scissors currently on the market are more difficult to prune higher branches

Such as the Chinese Utility Model Publication Patent Application No. CN203537935 is a novel length-adjustable electric fruit tree pruning shears. This patent document realizes electric pruning shears to adapt to pruning operations of different heights through an adjustable length extension rod, but because the motor Both the scissors and scissors are set on the head, and the extension rod is used as the part of the electrical connection to conduct the power supply. On the one hand, the center of gravity is far away from the hand-held part of the tail, which is inconvenient to use; on the other hand, in high humidity environments such as rain, it is easy to cause power consumption.
