[0027] Figure 5 And Figure 6 ​As shown, considering that different types of cutting tools 1 are needed when grinding the inner wall of the groove, this utility model also improves the structure of the cutting tool 1 so that the cutting tool 1 can adapt to groove structures of various specifications. Specifically, the cutting tool 1 is configured to include a handle section 101 and a cutting head section 102. The handle section 101 has a cylindrical structure, and the cutting head section 102 is composed of multiple arc-shaped plates, which are distributed at equal angles relative to the axis of the cutting tool 1. A connecting post 103 is integrally provided at one end of the handle section 101 near the cutting head section 102. A telescopic groove 105 is provided in the connecting post 103. The number of telescopic grooves 105 corresponds to the number of arc-shaped plates. A T-shaped connecting block 107 is telescopically provided in the telescopic groove 105. The inner side of the T-shaped connecting block 107 is an inclined surface, and the outer side extends out of the telescopic groove 105 and is fixedly connected to the corresponding arc-shaped plate. A spring 106 is fixedly provided on the outer side of the T-shaped connecting block 107 and is fixed to the inner wall of the telescopic groove 105. The middle part of the handle section 101 is connected by a screw. A threaded rod 104 is connected to the tool 1. One end of the threaded rod 104 moves through the end of the handle section 101 away from the cutter head section 102, and the other end moves through the end of the connecting post 103 away from the handle section 101. A conical block 108 is fixedly installed on the outer ring of a section of the threaded rod 104 inside the telescopic groove 105. The conical block 108 is in contact with the inclined surface on the inner side of the T-shaped connecting block 107. When the diameter of the groove is large, the threaded rod 104 can be rotated to move the conical block 108 toward the cutter head section 102. At this time, the conical block 108 abuts against the inclined surface on the T-shaped connecting block 107, which allows the T-shaped connecting block 107 to move outward in the telescopic groove 105. This causes the arc plate connected to the T-shaped connecting block 107 to move outward. Multiple arc plates can move outward at the same time, which increases the outer diameter of the cutter head section 102 formed by multiple arc plates. This makes the tool 1 suitable for machining groove structures with larger specifications, and facilitates adjustment and use.

[0028] It should be noted that the spring 106 serves to push the T-shaped connecting block 107 to press against the surface of the conical block 108, so that the cutter head section 102 can be adjusted in the opposite direction while maintaining a stable connection state, without affecting its use.
