The design concept of hedge trimmer is as follows:

1. The overall structure should be reasonable and convenient for users to operate and maintain. The body should be made of lightweight materials to reduce weight while ensuring sufficient strength and stability. Consider using metal chains as a power source to improve the cutting efficiency and quality of the machine. 2. Considering safety factors, it is necessary to install protective covers or guardrails to prevent fingers or other objects from being caught in the body. 3. It should have a moderately powerful output power system to meet the growth height and pruning needs of different plants; 4. The noise level should be within an acceptable range to avoid; 5. The selection and application of green and environmentally friendly materials ensure that no harmful gases or liquids are produced during the processing, which are harmful to human health and the environment; 6. The convenient operation interface includes a display screen and a control panel, striving for simplicity, ease of understanding, and usability; 7. Easy cleaning in the later stage, so that users can maintain and upkeep the equipment in a timely manner. 8. The appearance of the body should be beautiful and elegant, reflecting a certain cultural connotation. 9. It is due to factors such as good after-sales service guarantee and quality endorsement brought by brand recognition. In short, the birth of a hedge trimmer requires designers to think and practice from multiple dimensions in order to create products that meet market demand..
