The second magnetic stone 53 and the annular connecting plate 51 are arranged in a fixed structure, so that the second magnetic stone 53 will not loosen when being adsorbed and fixed, and the top of the fixing rod 52 A second magnetic stone 53 is fixedly connected, and a positioning mechanism 54 is installed at an equal distance in a ring shape at the bottom of the annular connecting plate 51. The positioning mechanism 54 includes a fixing plate 541, a first connecting rod 542, a connecting strip 543, a second connecting rod 544, a roller 545 and an annular rubber ring 546. The first connecting rod 542 is fixedly installed inside the fixing plate 541, and the outer surface of the first connecting rod 542 is fixedly connected to the connecting strip 543, and the inner surface of the other end of the connecting strip 543 is rotatably connected to the second connecting rod 544. At the same time, rollers 545 are symmetrically fixedly connected to the two ends of the second connecting rod 544. The interior of the roller 545 is fixedly connected to the end of the second connecting rod 544, and the roller 545 is connected to the outer surface of the second connecting rod 544. The second connecting rod 544 and the connecting strip 543 form a rotating structure, and the roller 545 and the connecting strip 543 are set to form a rotating structure, so that the roller 545 can be rolled and pressed along the top of the rubber, and the outer surface of the roller 545 is fixedly connected with an annular rubber ring 546, and the inside of the annular connecting plate 51 is rotatably connected to the side of the knife rod 6. The auxiliary component 5 also includes a bearing plate 55 and a return spring 56, and the bearing plate 55 is installed at an equal distance in a ring shape at the bottom of the annular connecting plate 51, and the return spring 56 is fixedly installed on the side of the bearing plate 55, and the end of the return spring 56 is fixedly connected to the side of the bearing plate 55, and the other end of the return spring 56 is fixedly connected to the side of the connecting strip 543 , and the connecting strip 543 forms an elastic structure with the supporting plate 55 through the reset spring 56. By setting the connecting strip 543 and the supporting plate 55 as the elastic structure, the positioning mechanism 54 of the auxiliary component 5 can be automatically reset when the knife rod 6 moves upward, and the bottom of the knife rod 6 is fixedly installed with a knife seat 7, and the side of the knife seat 7 is movably installed with a single crystal diamond blade 8, the top of the knife seat 7 is fixedly connected to the bottom of the knife rod 6, and the top of the knife rod 6 is fixedly connected to the bottom of the knife handle 1, and the knife seat 7 forms a fixed structure with the knife handle 1 through the knife rod 6. By setting the knife seat 7 and the knife handle 1 as a fixed structure, the knife seat 7 will not fall off when driving the single crystal diamond blade 8 to cut the rubber.

[0023] like Figure 1 and Figure 3As shown, a mounting groove 2 is provided on the outer surface of the knife handle 1, and a first magnetic stone 3 is fixedly installed on the top of the knife handle 1, and a positioning plate 4 is fixedly connected to the outer surface of the knife handle 1, a knife rod 6 is welded to the bottom of the knife handle 1, and an auxiliary component 5 is rotatably connected to the outer surface of the knife rod 6.

[0024] In summary, the single crystal diamond tool is firstly based on Figures 1 to 3 In the structure shown in the figure, the staff grasps the knife handle 1 and aligns the mounting groove 2 with the guide strip on the inner surface of the mounting seat, and then moves the knife handle 1 into the interior of the mounting seat. When the upper surface of the positioning plate 4 fits with the lower surface of the mounting seat, it means that the knife handle 1 is completely moved into the interior of the mounting seat. At this time, the knife handle 1 is initially fixed by the cooperation of the first magnetic stone 3, and then the internal structure of the mounting seat completes the further locking of the knife handle 1 to complete the installation of the tool. At this time, the top of the second magnetic stone 53 is adsorbed and connected with the fixed end at the bottom of the mounting seat. When the staff needs to use the tool to cut the rubber, the mounting seat drives the tool to move downward. As the knife rod 6 descends, the bottom of the roller 545 is fitted and connected with the top of the rubber. As the knife rod 6 continues to descend, At this time, through the rotation of the second connecting rod 544 and the first connecting rod 542 and the connection of the connecting strip 543, the roller 545 moves outward along the top of the rubber, so as to achieve the purpose of flattening and fixing the rubber. Then the mounting seat drives the tool handle 1 to rotate, so that the tool seat 7 drives the single crystal diamond blade 8 to cut the rubber. At this time, through the rotation between the tool rod 6 and the annular connecting plate 51, the tool seat 7 will not interfere with the limiting of the positioning mechanism 54 when driving the single crystal diamond blade 8 to rotate. When the single crystal diamond blade 8 is cut, the mounting seat drives the tool to move upward. At this time, through the cooperation of the reset spring 56 on the side of the supporting plate 55, the positioning mechanism 54 returns to its original position, so as to complete the processing of the sealing ring by the tool.
