[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-3 A disc tool blade grinding head includes two symmetrically arranged grinding sheets 2, each grinding sheet 2 is hinged at the end of a grinding sheet mounting block 1, the two grinding sheets 2 are close to each other and the side is a grinding surface, and the disc tool is located between the two grinding sheets 2. The two grinding sheets 2 are used to grind the disc tool in the middle, and when the grinding sheets 2 are pressed on the blade of the circular cutter disc and the cutter disc is rotated, the grinding sheets 2 grind the cutter disc.
