Branch pruning machine

The utility model provides a branch pruning machine. The branch pruning machine comprises a pruning mechanism, a first rotary mechanism, a rotary table, an arm frame assembly and a second rotary mechanism. The first slewing mechanism is used for driving the pruning mechanism to rotate in a first plane; one end of the arm support assembly is hinged to the rotary table, the other end of the arm support assembly is hinged to the trimming mechanism, the arm support assembly comprises a main arm, a swing arm and an adapter arm which are sequentially hinged end to end, a first linear driving part is hinged between the main arm and the rotary table, and a second linear driving part is hinged between the tail end of the main arm and the swing arm; the second swing mechanism is used for driving the adapter arm to rotate in a second plane, and the second plane is perpendicular to the first plane. The first linear driving part and the second linear driving part act cooperatively to drive the switching arm and the trimmi
