Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a saw device suitable for pruning trees mounted on a heavy-load unmanned helicopter. Background Art

[0002] With the application of drones, drones are equipped with tools and can be remotely controlled to perform operations, replacing manual movement over long distances. This makes it convenient for users to use and reduces their labor intensity. However, pruning a large number of trees is an operation that needs to be performed every year. Pruning workers need to carry ladders to the higher parts of the trees for pruning, which is less safe and not conducive to user operation.

Therefore, a tree pruning saw device suitable for being mounted on a heavy-load unmanned helicopter is proposed.
