[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 As shown, the present embodiment discloses a forestry pruning device, including a mounting plate 1, a movable block 2 is movably connected to the mounting plate 1, racks 3 are fixedly connected to both sides of the movable block 2, the two racks 3 are rotatably connected to the rotating shaft 4 on the sides away from each other, a gear 5 is fixedly mounted on the rotating shaft 4, and the gear 5 is meshed and connected with the corresponding rack 3; there are two pruning components 6, and the two pruning components 6 are respectively connected to the two rotating shafts 4; a small electric push rod 7 is connected to the mounting plate 1, and the action end of the small electric push rod 7 is connected to the movable block 2; the mounting plate 1 is connected to an auxiliary component 8 on the side away from the pruning component 6.

[0021] In this embodiment, the fixed end of the small electric push rod 7 is fixed on the mounting plate 1, the action end of the small electric push rod 7 is fixedly connected to one end of the movable block 2, and the bottom surface of the movable block 2 is in sliding contact with the mounting plate 1; the gear 5 is set as a semicircular gear 5; the small electric push rod 7 drives the movable block 2 to move in a straight line, and the racks 3 on both sides of the movable block 2 respectively drive the two gears 5 and the corresponding rotating shaft 4 to rotate in the opposite direction, and the rotating shaft 4 drives the pruning assembly 6 to rotate around the axis of the rotating shaft 4.

[0022] By adopting this solution, the small electric push rod 7, the movable block 2, the rack 3, the gear 5 and the rotating shaft 4 are provided to drive the two pruning components 6 to rotate in opposite directions, so that the shrub branches can be automatically cut off by opening and closing the two pruning components 6; the auxiliary component 8 is provided, so that the utility model can be conveniently operated when pruning shrubs.

[0023] In a further optimized solution, the pruning assembly 6 includes a handle 61 fixedly connected to the rotating shaft 4, and a cutter head 62 is fixedly connected to the end of the handle 61. The opening and closing of the two cutter heads 62 are controlled by a small electric push rod 7, so that the shrub branches can be automatically cut.

[0024] According to a further optimized solution, the auxiliary component 8 includes a carrying handle 81 and a grip 82 , and the carrying handle 81 and the grip 82 are respectively connected to the mounting plate 1 .

[0025] In this embodiment, the handle 82 is arranged horizontally and fixedly connected to the side wall of the mounting plate 1; the handle 81 is arranged vertically between the handle 82 and the pruning assembly 6, the handle 81 is arranged as a door-type structure, and the bottoms of the two side walls of the handle 81 are respectively fixedly connected to the side walls of the mounting plate 1.
