Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0015] Depend on Figures 1 to 3 The utility model comprises a diamond grinding wheel body 1 and a metal connecting substrate 2 installed on the top of the diamond grinding wheel body 1, a first fixed block 4 is fixedly installed on the top of the metal connecting substrate 2, a connecting shaft 3 is connected to the top of the first fixed block 4, the connecting shaft 3 is connected to the motor and can drive the first fixed block 4, the metal connecting substrate 2 and the diamond grinding wheel body 1 to rotate, so that the diamond grinding wheel body 1 can effectively perform the grinding operation, a square groove 15 is opened on the top of the first fixed block 4, a square clamping block 16 is fixedly installed on the bottom of the connecting shaft 3, and the square clamping block 16 is movably inserted in the inside of the square groove 15, so that the connecting shaft 3 can stably drive the diamond grinding wheel body 1 to rotate; the square clamping block 16 is clamped in the inside of the square groove 15, so that when the connecting shaft 3 rotates, the square clamping block 16 and the square groove 15 can stably and effectively drive the first fixed block 4, the metal connecting substrate 2 and the diamond grinding wheel body 1 to rotate.

[0016] Three inverted L-shaped rotating blocks 5 are installed at equal distances in an annular manner at the lower part of the connecting shaft 3, and connecting blocks 6 are installed at the lower parts of the three inverted L-shaped rotating blocks 5. The three connecting blocks 6 are connected to the first fixed block 4, and the upper parts of the three inverted L-shaped rotating blocks 5 are rotatably connected to adjusting rods 7. A threaded connection section 8 is provided on the surface of the connecting shaft 3, and a threaded tube 9 that can be adjusted up and down is threadedly connected at the threaded connection section 8. The tops of the three adjusting rods 7 are connected to the threaded tube 9; a bearing 10 is installed on the surface of the threaded tube 9, and three second fixed blocks 11 are fixedly installed at equal distances in an annular manner on the surface of the bearing 10. The three adjusting rods 7 are connected to the threaded tube 9. The top of the section rod 7 is rotatably connected to the three second fixed blocks 11 respectively, three inverted U-shaped blocks 12 are fixedly installed at equal intervals in an annular manner on the lower part of the connecting shaft 3, and the inverted L-shaped rotating block 5 is rotatably connected to the middle part of the inverted U-shaped block 12. Three slots 13 are opened in an annular manner at equal intervals on the surface of the first fixed block 4, and the three connecting blocks 6 are movably connected to the inside of the three slots 13 respectively. An adjusting ring 14 is fixedly installed on the upper part of the surface of the threaded tube 9, so that it can be effectively adjusted and connected and fixed. The cross-sections of the connecting block 6 and the slot 13 are both right-angled trapezoidal structures, so that the firmness of the connection can be ensured;

[0017] As shown in the accompanying drawings, when the diamond grinding wheel body 1 needs to be disassembled, the threaded tube 9 is rotated through the adjusting ring 14, so that the threaded tube 9 moves upward on the surface of the connecting shaft 3 through the threaded connection section 8. The upward movement of the threaded tube 9 will pull the three adjusting rods 7 to move upward through the bearing 10 and the three second fixed blocks 11. The upward movement of the three adjusting rods 7 will pull the three inverted L-shaped rotating blocks 5 to rotate. The rotation of the three inverted L-shaped rotating blocks 5 will drive the three connecting blocks 6 to move out from the inside of the three slots 13. At this time, the diamond grinding wheel body 1 and the metal connecting substrate 2 can be disassembled; and when installing, the three connecting blocks 6 are inserted into the inside of the three slots 13 to complete the connection and fixation.

[0018] A fixing ring 17 sleeved on the surface of the connecting shaft 3 is fixedly installed at the bottom of the threaded tube 9, and a triangular groove 18 is opened at an equal distance in an annular manner at the bottom of the fixing ring 17. A hollow tube 19 is fixedly installed at the lower part of the surface of the connecting shaft 3, and an inverted T-shaped pin 20 is movably inserted at the top of the hollow tube 19. A spring 23 is fixedly connected between the bottom of the inverted T-shaped pin 20 and the bottom of the hollow tube 19. A triangular block 21 inserted in the triangular groove 18 is fixedly connected to the top of the inverted T-shaped pin 20, and a toggle pin 22 is fixedly connected to the upper part of the inverted T-shaped pin 20, so as to effectively prevent the threaded tube 9 from being reversed and loosened when the connecting shaft 3 rotates, thereby ensuring firmness and stability;

[0019] When the threaded tube 9 rotates and moves downward, it drives the fixing ring 17 and the triangular slot 18 to rotate and move downward. The downward movement of the triangular slot 18 squeezes the triangular block 21 through the inclined surface of the triangular slot 18, which causes the triangular block 21 to move downward. The downward movement of the triangular block 21 compresses the spring 23. The triangular slot 18 and the triangular block 21 prevent the fixing ring 17 and the threaded tube 9 from automatically reversing, thereby effectively ensuring the firmness and stability of the adjustment.

[0020] When the diamond grinding wheel body 1 needs to be disassembled, first, the T-shaped pin 20 is pressed down by the push pin 22, so that the inverted T-shaped pin 20 moves downward to compress the spring 23. At the same time, the downward movement of the inverted T-shaped pin 20 will drive the triangular block 21 to move out from the inside of the triangular slot 18. At this time, the reverse rotation of the threaded tube 9 can drive the fixing ring 17 and the triangular slot 18 to reverse, and the reversal of the threaded tube 9 can move up on the surface of the connecting shaft 3 through the threaded connection section 8.

[0021] The high-stability diamond grinding wheel structure has a disassembly and assembly connection structure, which can conveniently perform disassembly and assembly operations on the diamond grinding wheel, and at the same time, the disassembly and assembly connection structure can ensure the stability and firmness of the installation of the diamond grinding wheel, thereby ensuring the safety of the use of the diamond grinding wheel. In addition, the high-stability diamond grinding wheel structure is simple in design, convenient and easy to adjust and operate, and stable and reliable in connection and use, and its performance can meet people's use needs.
