Background

An edger is a common garden tool intended for use in trimming or furrowing lawns. The working head of the trimmer generally comprises a motor and a blade connected to an output shaft of the motor, the cutting elements are generally vertically arranged to achieve trimming or ditching, and the motor can drive the cutting elements to perform trimming or ditching when being started. However, the cutting height needs to be adjusted to correspond to different cutting environments in the actual use process. When the cutting height of the existing trimmer is adjusted, only one roller normally moves synchronously, and the included angle between the connecting rod and the ground is in the range of 30-60 degrees when the connecting rod is adjusted to be longer (usually more than 1 meter and usually about 1.5 m), so that a user needs to lift or slightly bend the hand to cut grass, and the user is very easy to fatigue and has poor operation experience during operation.
