Abstract

The height-adjustable brush cutter comprises a machine body, machine frames and a blade, the machine frames comprise the first machine frame and the second machine frame, a sliding groove is formed in the second machine frame, two adjusting plates are fixedly connected to the top face of the first machine frame, racks are fixedly connected to the two adjusting plates, the two adjusting plates are arranged in a staggered mode, and a gap exists between the two adjusting plates. When the pruning range of the brush cutter needs to be adjusted, the adjusting rod slides inwards or outwards to enable the first gear or the second gear to be meshed with the rack on one adjusting plate, the adjusting rod is further rotated, and at the moment, along with rotation of the adjusting rod, the first gear or the second gear is meshed with the rack on one adjusting plate. The first machine frame gradually slides into or out of the sliding groove, so that the function of adjusting the length of the machine frame is achieved, the trimming range of the brush cutter is adjusted, and the trimming task is conveniently completed.
