[0002] As a cutting tool, the bevel cutter has a wide range of applications. It can be used to cut many metal or non-metal materials, and the cutting is quick and convenient. At present, in order to increase the cutting width, industry workers have made some improvements. A sliding cutting structure is set on the bevel cutter, so that the saw mechanism can slide relative to the workbench, so that the cutting width of the bevel cutter can be adjusted. Usually the above-mentioned sliding cutting mechanism includes two guide rails for slidingly connecting the bevel cutter. At present, a frequently occurring problem is that the ends of the two guide rails will be inconsistent during the assembly process and the placement process of the guide rails. When the mounting block is sleeved on the guide rails, the parallelism of the two guide rails cannot be guaranteed, resulting in low working accuracy of the bevel cutter and a high product scrap rate.
