DETAILED DESCRIPTION

[0020] 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 described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] See also Figure 1-7 The utility model provides an embodiment: a diamond polygonal cutter head, comprising a cutter head fixing body 1, a fixing bolt body 2 and a diamond cutter head body 3, the fixing bolt body 2 is arranged on the cutter head fixing body 1, the diamond cutter head body 3 is arranged on the fixing bolt body 2, the cutter head fixing body 1 comprises a cutter head fixing plate 4, a cutter head mounting groove 5 is provided in the middle of the bottom end of the cutter head fixing plate 4, a bolt limiting groove 6 is provided at the bottom end of one side of the cutter head fixing plate 4, a nut fixing groove 7 is provided at the bottom end of the other side of the cutter head fixing plate 4, and the cutter head mounting groove 5 is connected to the bolt limiting groove 6, and the cutter head mounting groove 5 is connected to the nut fixing groove 7.

[0022] The fixing bolt body 2 includes a bolt head 8, one side of the bolt head 8 is fixedly connected to a limiting rod 9, the end of the limiting rod 9 away from the bolt head 8 is fixedly connected to a threaded rod 10, and the outer diameter of the threaded rod 10 is smaller than the minimum outer diameter of the limiting rod 9, so that the limiting rod 9 can pass through the limiting hole 13, and a nut 11 is threadedly connected to the threaded rod 10.

[0023] The diamond bit body 3 includes a diamond bit 12, a limiting hole 13 is formed through the middle of the diamond bit 12, and a plurality of cutting tips 14 are arranged on the outer side of the diamond bit 12, and the number of the cutting tips 14 matches the number of sides of the diamond bit 12, for example, a quadrilateral diamond bit 12 has four cutting tips 14, and a pentagonal diamond bit 12 has five cutting tips 14.

[0024] The bolt head 8 matches the bolt limiting groove 6 , and the bolt head 8 is engaged in the bolt limiting groove 6 , so that the bolt head 8 is limited and fixed by the bolt limiting groove 6 .

[0025] The limiting rod 9 matches the limiting hole 13, and the limiting rod 9 is engaged in the limiting hole 13. The bolt head 8 is limited by the bolt limiting groove 6, thereby limiting the limiting rod 9, so that the limiting rod 9 limits the diamond bit 12 to prevent the diamond bit 12 from rotating.

At this time, the threaded rod 10 passes through the limiting hole 13 and is located inside the nut fixing groove 7, and the limiting rod 9 is inserted into the limiting hole 13. Then, the nut 11 is threadedly connected to the threaded rod 10 by external force to fix it. At this time, the limiting rod 9 limits and fixes the diamond cutter head 12. When the cutter tip 14 is worn during use and needs to be replaced, the diamond cutter head 12 is fixed by external force. Remove the nut 11 and push the threaded rod 10 close to the diamond bit 12 by external force. The movement of the threaded rod 10 drives the limiting rod 9 to slide inside the limiting hole 13. When the limiting rod 9 is completely out of the limiting hole 13, the diamond bit 12 is rotated by external force to replace the position of the cutting tip 14. The worn cutting tip 14 is rotated to the top and the new cutting tip 14 is rotated to the bottom. Then, the bolt head 8 is pushed by external force to drive the limiting rod 9 to slide and be inserted into the limiting hole 13. Then, the nut 11 is tightened and fixed by external force.
