When in use, the periphery is turned through the acute angle end and the end face is turned through the obtuse angle end, which further improves the utilization rate of the blade.

[0022] In this embodiment, in order to design reasonably and facilitate the installation of the blade, a wear-resistant block mounting hole 5 is provided in the middle of the blade and passes through the blade. A wear-resistant block 6 is installed in the wear-resistant block mounting hole. A limiting hole 7 is provided in the middle of the wear-resistant block and passes through the wear-resistant block. The installation of the blade is achieved through the limiting hole. At the same time, due to the presence of the wear-resistant block, damage to the blade installation position and resulting in the scrapping of the blade can be further avoided.

[0023] In this embodiment, in order to further avoid damage between the blade and the bottom of the diamond groove and to facilitate the installation of the blade, a gasket block 8 is installed on the bottom of the diamond groove, and the blade abuts against the gasket block. A limit block 9 for fixing the blade is installed on the cutting surface of the cutter head, and the blade is clamped between the gasket block and the limit block.

[0024] In this embodiment, in order to further fix the blade on the gasket block, a limiting post 10 is provided on the gasket block corresponding to the limiting hole of the wear-resistant block.
