[0002] The main function of the vegetation pruning knife for municipal gardens is to prune and arrange vegetation, including trees, shrubs, lawns, etc. When the blade of the vegetation pruning knife contacts the plant, the blade applies pressure to cut the plant tissue. Through the blade design and power drive, it can achieve effective pruning and arranging of vegetation, improving pruning efficiency and quality;
[0003] Garden pruning shears are generally selected according to the type of plants to be pruned, and high branch shears are usually used for pruning plant branches at high places. Traditional high branch shears are equipped with a transmission device, usually a pull-rope design, and the cutting action of the blade is achieved by pulling the rope. Although this method can effectively cope with the pruning of high branches, the staff needs to hold and control the long pole of the high branch shears, usually using one hand to control the rope, which is not flexible enough. When cutting, the strength of one hand is sometimes not enough to cut, which is more laborious. In addition, when using a rope to control the handle, the rope is long and easy to entangle with branches and leaves during use, and it is difficult to get rid of it, affecting subsequent normal use.
