The outer end of the knife insert strip 8 is connected with a blade 9, and the outer side of the knife insert strip 8 and the inner side of the mounting sleeve 4 are detachably mounted. A driving mechanism is arranged inside the frame 1 and on the rear side of the two sets of movable strips 3; the two sets of knife insert strips 8 are respectively inserted into the inner sides of the corresponding mounting sleeves 4, and after they are in place, the tightening hand 7 is screwed to rotate the tightening screw 6, and the tightening screw 6 is screwed with the tightening screw sleeve 5 to act inward on the outer side of the knife insert strip 8 to tighten. When in use, the driving mechanism on the frame 1 makes the two sets of movable strips 3 reciprocate through the constraint of the constraint shaft 2, thereby driving the two sets of blades 9 to move and act on the branches and leaves at the corresponding positions.

[0025] The driving mechanism includes a reciprocating motor 10, a threaded rod 11, a sliding sleeve 12, a sliding rod 13, an articulated block 14, an articulated shaft 15, an articulated frame 16 and a threaded sleeve 17. The left middle side of the outer end of the frame 1 is connected to the inner end of the reciprocating motor 10, the output end of the reciprocating motor 10 is connected to one end of the threaded rod 11, the threaded rod 11 is rotatably connected to the inner side of the frame 1, and the inner sides of the rear parts of the two groups of movable bars 3 are respectively connected to a group of sliding sleeves 12, the inner sides of the sliding sleeves 12 are slidably connected to the outer sides of the sliding rods 13, and the rear ends of the sliding rods 13 are connected to the hinged The outer side of the hinge block 14 is movably connected with the inner side of the hinge frame 16 via the hinge shaft 15. A threaded sleeve 17 is arranged inside the hinge frame 16. The threaded sleeve 17 is screwed on the outer side of the threaded rod 11. When the reciprocating motor 10 is running, the threaded rod 11 rotates, and the threaded rod 11 is screwed with the two groups of threaded sleeves 17, and is constrained by the hinge shaft 15 to move on the outer side of the hinge block 14 through the two groups of hinge frames 16, and the sliding rod 13 is correspondingly extended and retracted in the sliding sleeve 12 to drive the movable bar 3 to move.
