[0002] A grinding wheel is a common grinding tool, usually used for grinding, polishing or finishing materials such as metal, glass, ceramics, and plastics. It consists of abrasives, binders, and holes. The abrasives can be high-hardness materials such as aluminum oxide, silicon carbide, and diamond, which achieve grinding by contacting the surface of the workpiece. The binder bonds the abrasives together and combines them with the grinding wheel base. The holes are used for heat dissipation, chip removal, and installation. Grinding wheels are widely used in metal processing, woodworking, glass processing, and other industries. They have the characteristics of high grinding efficiency, good processing accuracy, and long service life.

[0003] The grinding wheels in the prior art are generally used in conjunction with angle grinders. When grinding objects with larger curved surfaces, grinding wheels with different angles are required. The curved grinding wheel and the ordinary grinding wheel are alternately replaced and polished to achieve polishing of the object. However, the grinding wheels in the prior art are generally fixed to the surface of one side of the angle grinder by bolts during installation and disassembly. Therefore, when the grinding wheel needs to be replaced, it is troublesome to rotate the bolts to achieve disassembly, which is time-consuming and labor-intensive. Utility Model Content

When the alignment is completed, insert the angle grinder into the inner wall of the spiral hole 4. By rotating, the angle grinder and the spiral hole 4 are twisted together, thereby achieving the installation and fixation of the fixing rod 3. Embodiment 2

[0026] Based on the above embodiment 1, please refer to FIG. Figure 6-Figure 8 The quick-release assembly includes a fixing rod 3, a spiral hole 4 is provided on the top surface of the fixing rod 3, a sliding groove 5 is provided on the inner wall of the fixing rod 3, an adjusting groove 6 is provided on the bottom surface of the fixing rod 3, a limiting block 7 is installed on the inner wall of the sliding groove 5, an adjusting plate 8 is installed on the inner wall of the limiting block 7, an adjusting rod 9 is installed on the inner wall of the adjusting groove 6, a telescopic spring 10 is installed on the outer surface of the adjusting rod 9, the fixing rod 3 is installed on the inner wall of the plug-in groove 13, and a limiting groove 11 is provided on the inner wall of the plug-in groove 13.

[0027] The outer surface of the fixing rod 3 is movably connected with the inner wall of the insertion groove 13. There are two limiting grooves 11, which are distributed on one side and the other side surface of the inner wall of the insertion groove 13. The inner wall of the insertion groove 13 is movably contacted with the outer surface of the limiting block 7.

[0028] The inner wall of the sliding groove 5 is connected to the inner wall of the adjusting groove 6. The limit blocks 7 are two inner walls of the adjusting groove 6 that are equidistantly distributed. The limit blocks 7 are in active contact with the inner wall of the sliding groove 5. An adjusting rod 9 is installed on one side surface of each limit block 7. The adjusting rod 9 is movably and rotatably connected to the limit blocks 7.

[0029] One end of the telescopic spring 10 contacts the outer surface of the adjusting rod 9 , and the other end of the telescopic spring 10 contacts the inner wall of the adjusting groove 6 . The adjusting rod 9 is movably and rotatably connected to the two adjusting plates 8 .

[0030] When the adjusting rod 9 moves, the limiting block 7 will be pulled by the adjusting plate 8 to move on the inner wall of the sliding groove 5. At this time, the moving limiting block 7 will be retracted into the inner wall of the sliding groove 5. At this time, the fixing rod 3 is pulled out from the inner wall of the plug-in groove 13 to realize the disassembly of the grinding wheel. When the disassembly is completed, the support member 1 is turned 90 degrees so that the plug-in groove 13 on the other side of the support member 1 is aligned with the fixing rod 3 and inserted, so as to realize the adjustment of switching between the grinding bevel 203 and the grinding curved surface 201.

[0031] The working principle and use process of the utility model are as follows: when it is necessary to use a curved surface grinding wheel, the outer surface of the fixing rod 3 is held, and the spiral hole 4 opened on its top surface is aligned with one end of the angle grinder. When the alignment is completed, the angle grinder is inserted into the inner wall of the spiral hole 4, and the angle grinder and the spiral hole 4 are twisted together by rotation. When the twisting is completed, the support member 1 is picked up, and the fixing rod 3 is inserted into the plug-in groove 13 opened on the top surface of the support member 1. At this time, the limit block 7 on the inner wall of the sliding groove 5 is in an extended state due to the elastic force of the telescopic spring 10. When the fixing rod 3 is inserted into the inner wall of the plug-in groove 13, the limit block 7 will contact with the inner wall of the plug-in hole, and due to the friction force, the limit block 7 will shrink toward the inner wall of the sliding groove 5. When the limit block 7 moves on the inner wall of the sliding groove 5, its inner wall will rotate flexibly. When the adjusting rod 9 moves, the adjusting plate 8 movably connected to the inner wall of the sliding groove 5 will move. At this time, the adjusting plate 8 that is pushed will squeeze the adjusting rod 9. When the adjusting rod 9 is squeezed, it will move on the inner wall of the adjusting groove 6 and squeeze the telescopic spring 10 installed on its outer surface. As the fixing rod 3 continues to go deeper, the fixing rod 3 will move to one side surface of the limiting groove 11. When the movement is completed, because the inner wall of the plug-in groove 13 no longer squeezes the limiting block 7, the stressed telescopic spring 10 will push the adjusting rod 9 to move. When the adjusting rod 9 moves, the adjusting plate 8 movably connected to the inner wall of the sliding groove 5 will move. At this time, the adjusting plate 8 that is pushed will push out the limiting block 7 on the inner wall of the sliding groove 5. At this time, the pushed out limiting block 7 will contact with the inner wall of the limiting groove 11, thereby fixing the fixing rod 3 and the inner wall of the support 1 to each other through the limiting block 7.

[0032] When it is necessary to use the grinding bevel 203 or the grinding curved surface 201, the adjusting rod 9 in the adjusting groove 6 is pulled. When the adjusting rod 9 is pulled, the adjusting rod 9 will move on the inner wall of the adjusting groove 6. When the adjusting rod 9 moves, the telescopic spring 10 will be squeezed. And because the adjusting rod 9 is connected to the limit block 7 through the adjusting plate 8, when the adjusting rod 9 moves, the limit block 7 will be pulled by the adjusting plate 8 to move on the inner wall of the sliding groove 5. At this time, the moving limit block 7 will retract into the inner wall of the sliding groove 5. At this time, the fixing rod 3 is pulled out from the inner wall of the plug-in groove 13, thereby realizing the disassembly of the grinding wheel. When the disassembly is completed, the support member 1 is turned 90 degrees so that the plug-in groove 13 on the other side of the support member 1 is aligned with the fixing rod 3 and inserted, so as to realize the adjustment of the switching of the grinding bevel 203 or the grinding curved surface 201.
