Grass trimmer

Abstract

The invention discloses a grass trimmer which includes an extension rod, a handle assembly, a working head, a motor, and cutting elements. The motor drives the cutting elements to rotate, due to which the cutting elements begin to work. The cutting elements are provided with cutting edges which are made of metal. The optimal cutting edges are hard blades. As the hard blades with metal cutting edges replace regular mowing lines, the energy consumption of the grass trimmer is reduced. The grass trimmer does not have to change lines. At the same time, the kinetic energy produced by the rotation of the cutting elements and the speed of the cutting elements are within limits. The safety of the grass cutting with the metal cutting edges is also improved.

Description

technical field [0001] The invention relates to garden tools, in particular to a lawnmower. Background technique [0002] As a garden tool for turf trimming, the mower is being favored by more and more users. The mowing machine generally drives the mowing wire to mow grass, usually including a lengthwise extending extension rod, a mowing head arranged at one end of the extension rod, and a handle arranged on the extension rod and set at a certain distance from the mowing head , The motor that drives the mowing head to rotate, and the battery pack that provides energy for the motor. When working, the mowing head is driven to rotate to drive the mowing line to rotate synchronously so as to mow grass. In the specific operation mode, the user holds the grass trimmer through the handle to carry out grass trimming or edge trimming. [0003] The mowing line of the mowing machine is usually made of nylon or plastic material, and the grass is broken by the high-speed rotation of t...

AI Technical Summary

Problems solved by technology

Excessive rotation speed will inevitably lead to excessive power consumption, requiring more energy consumption

If it is powered by DC power, the working time of a single battery pack is shorter
