Description

Special trimming tool for eucalyptus

Technical Field

The utility model belongs to the technical field of the eucalyptus is pruned, concretely relates to special clipper of eucalyptus.

Background

Eucalyptus, also known as Eucalyptus globulus, is a general term for plants in the genus Eucalyptus and the family Myrtaceae. The eucalyptus has more than six species, most of which are evergreen tall trees, and the minority of which are small trees, and has a periodic dead leaf shedding phenomenon within one year. Eucalyptus is suitable for growing on sunny plains, hillsides or roadside. The eucalyptus has fast growth speed, and the wood is hard and corrosion resistant, thereby being a very good wood board production raw material. In order to promote the growth of the trunk of the eucalyptus, branches and leaves of the eucalyptus need to be trimmed regularly. Most of existing tree pruning tools are scissors, sickles and the like, and can be used together with ladders to prune branches and leaves at higher positions. However, eucalyptus grows rapidly and is tall and tall, and the higher branches and leaves cannot be reached by using a common ladder. If the pruning of branches and leaves at high places is carried out by manual climbing, the pruning operation of large-area eucalyptus forests cannot be met. The condition that uses telescopic link collocation clipper to carry out the operation exists among the prior art, but handheld telescopic link produces fatigue easily, and the branch and leaf that the eminence was pruned in addition drops with the trunk separation and injures the staff under the tree easily by a crashing object.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
