The L-shaped plate 42 and the drive plate 43 are engaged, facilitating the docking and separation of the L-shaped plate 42 and the drive plate 43 during disassembly and assembly, thus facilitating maintenance and replacement of the second pruning blade 41 and improving the practicality of the device. The housing 1 adopts a split structure, allowing the internal parts of the housing 1 to be exposed during maintenance by disassembling the housing 12. The U-shaped connecting plate 32 is fixedly connected to the top of the inner wall of the upper housing 11 by screws for easy disassembly. In use, the motor 21 drives the turntable 22 to rotate. The first connecting shaft 23 at the bottom of the turntable 22 rotates around the axis of the turntable 22. Through the transmission of the connecting rod 24, the first connecting shaft 23 drives the drive plate 43 to reciprocate. When the drive plate 43 reciprocates, the trapezoidal slide rod 47 slides inside the slide rail 46. The reciprocating motion of the drive plate 43 drives the L-shaped plate 42 and the second pruning blade 41 to reciprocate. The second pruning blade 41 and the first pruning blade 31 work together to prune the green plants. When the second pruning blade 41 reciprocates, the strip groove 48 slides along the stud 332 to improve the stability of the second pruning blade 41 during reciprocating motion.
