A limiting mechanism is provided inside the cavity of the housing 1 to be inserted into the blade base plate 3. The positioning rods 2 at both ends facilitate the positioning and limiting of the blade base plate 3. The positioning mechanism is quickly installed using a tool cover plate 8, which protects the positioning mechanism and tool holder 4. A positioning port 9 allows one end of the tool cover plate 8 to be inserted into the positioning rod 2 by rotating it. The tool cover plate 8 is then clamped and fixed by the housing 1, enabling quick installation. A protective head plate 10 protects the other end of the tool cover plate 8 and the tool base plate 3. Toothed cutting heads 5, located on the side walls at both ends of the tool holder 4, move rapidly and repeatedly via a drive component, working in conjunction with the tool base plate. The toothed blades 5 on both sides of the plate 3 are used to trim the green plants. Positioning rods 11 located on both sides of the inner side wall of the protective head plate 10 are inserted into the mounting slots 12 of the blade holder 4 to reinforce its support. The drive cam connection port 7 facilitates the installation of the blade holder 4 and the drive component using bolts or other means. The positioning mechanism facilitates the positioning of the blade holder 4 and the blade base plate 3. The positioning rods 11 are inserted into one end of the blade holder 4, and the drive cam connection port 7 is used to position the blade holder 4. The other end is installed to quickly install the blade holder 4 to the machine. When disassembly is required, the housing 1 is opened, the blade cover plate 8 is rotated to open the blade holder, the drive cam connection port 7 is disassembled from the drive component, and the protective head plate 10 is pulled out so that the blade holder 4 can be removed from the limit position. This completes the disassembly of the blade holder 4, thus solving the problems of inconvenient installation of the blade and blade holder support plate of the existing hedge trimmer, low efficiency, and the fact that plant residue sap will cause the screws to rust after long-term use, making it inconvenient to disassemble and replace the blade or to perform maintenance on the inside of the machine housing.

One end of the limiting rod 16 passes through the corresponding first limiting port 17 and second limiting port 18. The rod wall of the limiting rod 16 at both ends is sleeved with a spring 19. By using the provided limiting rod 16, the spring 19 presses the lower end into the first limiting port 17 and the second limiting port 18, thereby limiting and fixing the blade base plate 3 and the positioning rod 2 to prevent vertical movement.

[0031] To limit and fix the protective head plate 10 and the blade base plate 3, such as Figure 1 , 3 As shown in Figure 4, the protective head plate 10 and the blade base plate 3 have mounting holes 20 on their side walls at both ends, and mounting threaded pins 21 are inserted therein. One end of the mounting threaded pin 21 passes through the mounting hole 20 and is threadedly connected to a threaded cap 22. By using the mounting threaded pin 21, which passes through the mounting hole 20 and is threadedly connected to the threaded cap 22, the protective head plate 10 and the blade base plate 3 are fixed and limited.

[0032] To limit and protect the tool holder 4 while reducing the damping of the tool holder 4 during repeated movements, such as Figure 2 and 4 As shown, the inner wall of the cutter cover plate 8 is rotatably connected with ball bearings 23. By using the ball bearings 23, the cutter holder 4 is limited and protected while the damping of the cutter holder 4 during repeated movement is reduced.

[0033] To prevent the base plate 3, tool holder 4, toothed cutter head 5, and tool cover plate 8 from rusting, such as Figure 1-4As shown, the surfaces of the blade base plate 3, blade holder 4, toothed blade head 5, and blade cover plate 8 are all coated with Teflon anti-rust coating. The other ends of the limit rods 16 at both ends pass through the side wall of the bracket 15 and are rotatably connected to the handles 24. The Teflon anti-rust coating prevents the blade base plate 3, blade holder 4, toothed blade head 5, and blade cover plate 8 from rusting, thereby increasing their service life. The handles 24 facilitate the operation of the limit rods 16.
