Description

Technical Field

[0001] The utility model relates to the technical field of pruning machines, in particular to a ball-shaped pruning machine for greening tree branches. Background Art

[0002] Compared with traditional manually operated scissors, using a pruning machine to prune branches, shrubs, etc. greatly reduces labor intensity and improves efficiency. With the increase in greening, pruning machines will become an indispensable garden tool. However, in actual application to landscape trees, in order to ensure the overall aesthetics, the landscape trees need to be pruned into a spherical shape, which places high demands on the operator's skills. By pruning in different directions, the landscape trees can be pruned into a spherical shape. However, for taller and larger trees, pruning them into a spherical shape will become more difficult, requiring the operator to observe and prune them multiple times to ensure the shape of the tree. Therefore, in order to reduce the labor intensity of the operator and at the same time prune the trees in an all-round way to improve work efficiency, it is necessary to further optimize the scissor structure on the pruning machine.
