The plant pruning shears have the advantages that the plant pruning shears are simple in structure, the shear handles and the blades are of a split structure, the blades canbe replaced conveniently, and the function of the shears can be changed to serve as a sickle by the mounting position change of the blades.

Description

technical field [0001] The invention belongs to the field of garden work tools, in particular to a plant pruning knife for forestry. Background technique [0002] When trimming plant branches in forestry, pruning knives are often needed. The existing pruning knives have a single function, the blade and the pruning knife body are integrally formed, and most of the blades are linear blades. During the pruning process, it is easy to slip, and the branches will slide on the blade or even break away from the pruning knife, which is time-consuming and laborious; in addition, the existing pruning knife has poor flexibility, can only be used as a single scissors, and cannot be deformed. Contents of the invention [0003] The purpose of the present invention is to provide a plant pruning knife for forestry. The structure of the present invention is simple. The scissors are designed as a split structure of the handle and the blade, which not only facilitates the replacement of the b...
