Description
Technical Field
The present invention relates to a cutting wire and a vegetation cutting machine using the same.
Background
Generally, cutting tools for trimming branches and leaves, lawns and the like are arranged on outdoor gardening cutting tools such as a grass trimmer, but the grass trimmer in the current market generally adopts nylon to make cutting lines, and the cutting lines are used as the tools to cut grass under the high-speed rotation state of a grass trimmer head, so that the self weight of the grass trimmer is reduced, an operator is not easy to fatigue during cutting, and the cost of the grass trimmer is reduced; however, the nylon cutting line has disadvantages, mainly that the nylon material has poor wear resistance and low strength, which causes the cutting line to be worn and broken frequently in the grass mowing process, and in order to make up for the disadvantages, the conventional practice is to arrange a wire spool with a larger diameter on the grass mowing head for winding the cutting line for one circle, thereby ensuring the normal use in the cutting process; in order to ensure the grass cutting quality and grass cutting efficiency, the grass cutting machine needs to pay off or change the line in time to supplement the length of the cut grass in the using process, an operator needs to pay attention to the working state of the cutting line in the cutting process to adjust the cutting line in time, and the line is frequently changed or paid off in the operating process, so that much inconvenience is brought to the operation. For some grass trimmers driven by a battery, additional driving energy is required to drive a wire spool arranged on a working head and a coil on the wire spool, so that the cutting service time of the grass trimmer after the battery is charged once is shortened, and if a standby battery is arranged on the grass trimmer, the cost of the grass trimmer is correspondingly increased.
