In this process, the waste edges are completely pushed to the outside and fall into the waste collection box.

[0014] Furthermore, in order to better implement the present invention, the S4 is specifically: when it is determined by image recognition technology that missed cutting occurs, it means that the position of the trimmer is too far outward, and the PLC controller is used to control the first telescopic rod to retract to increase the width of the waste edge; when it is determined by image recognition technology that crooked cutting occurs, it means that the driven roller is not placed horizontally, and the adjustment bolts on both sides are adjusted and confirmed to be adjusted to a horizontal position through the observation window.
