[0013] A drive motor is arranged on the seat body, and one end of the outer cylinder rod is fixed on the drive motor.

[0014] A drive screw is arranged inside the outer cylinder rod, one end of the drive screw is fixedly connected with the drive end of the drive motor, and the drive screw is screwed with the threaded hole on the lower end of the telescopic inner cylinder rod.

[0015] The beneficial effects of the above technical solution are that the drive motor drives the drive screw to rotate, the drive screw drives the telescopic inner cylinder rod to move telescopically inside the outer cylinder rod, and then the moving blade moves away from or approaches the static blade, realizing the automatic opening and closing of the blade part of the scissors.

[0016] Further, a limiting groove is arranged on each of the opposite inner walls of the outer cylinder rod, and a limiting block is fixed on each of the opposite outer walls of the telescopic inner cylinder rod, and the limiting block is slidably connected with the limiting groove.

[0017] The beneficial effects of the above technical solution are that the limiting block and the limiting groove are slidably matched, which can prevent the telescopic inner cylinder rod from rotating, so that the telescopic inner cylinder rod can only move telescopically along the length direction of the outer cylinder rod, thereby realizing the moving blade moving away from or approaching the static blade.

[0018] Further, a rotating motor is fixed on one side wall of the seat body, and the drive motor is fixed on the drive end of the rotating motor.

[0019] The beneficial effects produced by the above technical scheme are as follows: before cutting, the moving blade and the static blade are rotated to the vertical state by the rotating motor, so that the moving blade and the static blade can extend into the gap between adjacent plants, and then the moving blade and the static blade are moved to the target plant position, thereby avoiding the problem that the moving blade and the static blade are easily pressed down adjacent plants due to being in the horizontal position, and then the moving blade and the static blade are rotated to the horizontal state by the rotating motor, and the moving blade and the static blade are located on both sides of the plant respectively, and then the driving motor drives the moving blade to move to the static blade direction to cut off the plant.

[0020] Further, the handle is hingedly connected with the seat body.

[0021] The beneficial effects produced by the above technical scheme are as follows: the position of the handle can be adjusted according to the habit or comfort of the operator. BRIEF DESCRIPTION OF DRAWINGS
