Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-Figure 3 As shown, this specific embodiment discloses a bilateral trimmer, including a frame 1, wheels, a first cutting knife 4, a second cutting knife 5, an upper cutting knife adjustment frame 6, a lower cutting knife adjustment frame 7, a power supply 8 and a controller 9, wherein the wheels are arranged below the frame 1, the first cutting knife 4 and the second cutting knife 5 are arranged on both sides of the front end of the frame 1, the first cutting knife 4 and the second cutting knife 5 are arranged vertically, and the cutting blades of the first cutting knife 4 and the second cutting knife 5 are arranged forward, a first driving motor 41 for driving the first cutting knife 4 is arranged above the first cutting knife 4, and a second driving motor 51 for driving the second cutting knife 5 is arranged above the second cutting knife 5, the power supply 8 and the controller 9 are fixed on the frame 1, and the reciprocating blades on the first cutting knife 4 and the second cutting knife 5 are driven by the first driving motor 41 and the second driving motor 51 respectively to reciprocate and cut to achieve pruning branches and leaves. It is feasible that the reciprocating action can be achieved by an eccentric wheel, and the motor drives the eccentric wheel to rotate, and the eccentric wheel drives the cutting knife.

[0016] It is feasible that the first cutting knife 4 and the second cutting knife 5 are connected by an upper cutting knife adjusting frame 6 and a lower cutting knife adjusting frame 7, and the upper cutting knife adjusting frame 6 and the lower cutting knife adjusting frame 7 are adjustably arranged on the frame 1. The specific adjustable method is to fix the rotating shaft by a nut that can be tightened and loosened, and the upper cutting knife adjusting frame 6 and the lower cutting knife adjusting frame 7 can be rotated after loosening.

[0017] Specifically, the middle position of the upper cutting knife adjusting frame 6 and the lower cutting knife adjusting frame 7 is connected to the front section of the frame 1 through an adjustable rotating shaft, and the upper cutting knife adjusting frame 6 and the lower cutting knife adjusting frame 7 can rotate around the rotating shaft to drive the first cutting knife 4 and the second cutting knife 5 to adjust the inclination angle. In order to keep the angle of the cutting knife vertical, the upper cutting knife adjusting frame 6 and the lower cutting knife adjusting frame 7 are connected to the front fork 21, and a connecting frame is welded at the position where the upper cutting knife adjusting frame 6 is connected, so as to ensure that the upper cutting knife adjusting frame 6 and the lower cutting knife adjusting frame 7 are on the same vertical plane, so as to facilitate adjustment.

[0018] A feasible implementation is that, the upper cutter adjustment frame 6 includes two upper arc connecting rods 61, an upper arc chute 62 is arranged in the middle of the two upper arc connecting rods 61, the two upper arc connecting rods 61 are stacked at adjacent ends and connected and fixed on the frame 1 through a rotating shaft, and the rotating shaft for connection is fixed by bolts, and the lower cutter adjustment frame 7 includes two lower arc connecting rods 71, a lower arc chute 72 is arranged in the middle of the two lower arc connecting rods 71, the two lower arc connecting rods 71 ​​are stacked at adjacent ends and connected and fixed on the frame 1 through a rotating shaft, and the rotating shaft for connection is fixed by bolts, and the upper arc chute 62 and the lower arc chute 72 can slide relative to each other under the restriction of their corresponding rotating shafts when the bolts are loosened. That is, when adjustment is required, the sliding connecting rod, forming any angle and then fixing it by a nut can realize the angle adjustment of the cutter, and the adjustment in opposite or opposite directions can realize the spacing adjustment of the two cutters. Thus, the cutter can form any angle to adapt to the different directions formed by mountain planting and the different appearances of tea trees caused by terrain changes. This situation mainly deals with slopes, and the trimmer cannot be adjusted to the same angle as the slope. In this case, it can be achieved by adjusting the cutting knife.
