The design concept of the extended hedge trimmer is as follows:

1. Functional analysis: The machine needs to have high-quality cutting function to adapt to the needs of different plants and environments. At the same time, it should have strong power characteristics to ensure cutting depth and quality; Safety protection devices should also be equipped to ensure the personal safety of operators. In addition, factors such as ease of operation, durability, and environmental characteristics also need to be considered. 2. Material selection: Steel is used to manufacture the blade and body parts, ensuring strength and toughness; The surface of the body can be coated with anti-corrosion layer or wear-resistant material to extend its service life. 3. Design concept: organically integrate streamlined beauty and mechanical feeling, making the entire shape smooth, beautiful and full of strength; 4. The design of the extended model is mainly to meet a wider range of usage needs and improve work efficiency, and to quickly and effectively process different green areas; 5. Due to the frequent use of this device in gardens, attention should be paid to the weight of the device. It should not be too heavy or bulky, as it can be difficult to move and inconvenient for some female users with low strength. Therefore, it is necessary to control the net weight of the device reasonably. In addition, for the problem of many weeds in lawns or shrubs, low-speed slow-moving can be used to clean them, which can avoid high-speed running and scratching these vegetation. It can also effectively remove various stubborn weeds and other characteristics; The above is the general design thinking process. I hope it can help you. However, this is only a preliminary design plan that needs further research and improvement before it can be put into production trial~
