[0032] A fixing mechanism, which is arranged inside the resin grinding wheel 4;

[0033] The mechanism for easy installation is arranged on the output end of the grinder 1, and the mechanism for easy installation includes a fixed plate 3, a groove 5, a perforation 6, a first slide groove 7, a threaded groove 8, a fixed block 9, a second slide groove 10, a slide column 11, a spring 12 and a limit block 13.

[0034] Further, the fixed disc 3 is fixedly connected to the output end of the grinder 1, the groove 5 is provided on the outer surface of the resin grinding wheel 4, the through hole 6 is provided on the outer surface of the groove 5, the through hole 6 penetrates the resin grinding wheel 4, and two first slide grooves 7 are provided on the outer surface of the groove 5, and the two first slide grooves 7 penetrate the resin grinding wheel 4;

[0035] The thread groove 8 is provided on the outer surface of the fixed plate 3, the two fixed blocks 9 are fixedly connected to the fixed plate 3, the two second slide grooves 10 are provided on the outer surface of the corresponding fixed blocks 9, the two second slide grooves 10 correspond to each other, the inner walls of the two second slide grooves 10 are fixedly connected to the corresponding springs 12, the two slide posts 11 are slidably connected to the corresponding second slide grooves 10, the ends of the two springs 12 away from the corresponding second slide grooves 10 are fixedly connected to the corresponding slide posts 11, the two limit blocks 13 are fixedly connected to the corresponding slide posts 11, and the two limit blocks 13 are slidably connected to the corresponding second slide grooves 10;

[0036] The two first sliding grooves 7 are slidably connected to the corresponding fixing blocks 9 .

[0037] Furthermore, the fixing mechanism includes a fixing plate 15, which is arranged inside the resin grinding wheel 4, and a connecting groove 17 is formed on the outer surface of the fixing plate 15, and a bolt 18 is slidably connected inside the connecting groove 17, and the bolt 18 is threadedly connected to the thread groove 8;

[0038] Two connecting columns 16 are fixedly connected to the outer surface of the fixing plate 15 . Connecting holes 14 are formed on the outer surfaces of the two sliding columns 11 . One end of the two sliding columns 11 is spherical. The two connecting holes 14 are slidably connected to the corresponding connecting columns 16 .

[0039] When the two fixing blocks 9 are moved into the interior of the resin grinding wheel 4, the two first sliding grooves 7 squeeze the corresponding sliding posts 11, and the movement of the two sliding posts 11 compresses the corresponding springs 12. Then, when the two sliding posts 11 pass through the first sliding grooves 7, the two sliding posts 11 return to their original positions under the automatic reset characteristics of the corresponding springs 12, so that the resin grinding wheel 4 is simply fixed and installed and will not fall off. The use of the device can quickly install the resin grinding wheel 4 through the limiting of the two sliding posts 11, which is convenient for the tight installation of the resin grinding wheel 4 and avoids the need to hold the resin grinding wheel with one hand during installation, thereby saving time and improving installation efficiency.

[0040] Furthermore, when using the device, after the resin grinding wheel 4 is simply installed, it is necessary to tighten and fix the resin grinding wheel 4, pick up the fixing plate 15, plug it into the corresponding connecting hole 14 through the two connecting columns 16, and then pick up the bolt 18, pass the bolt 18 through the connecting groove 17 and the through hole 6 and threadedly connect it with the thread groove 8, rotate the bolt 18, so that the bolt 18 and the thread groove 8 are tightened and connected, the movement of the bolt 18 drives the fixing plate 15 to move, and the movement of the fixing plate 15 drives the two connecting columns 16 to move, and the movement of the two connecting columns 16 squeezes and fixes the connecting hole 14, so that when the resin grinding wheel 4 rotates, the spring 12 is prevented from shaking due to the influence of centrifugal force, the shaking of the resin grinding wheel 4 is reduced, and the failure and falling off are avoided, and the resin grinding wheel 4 is fixed for the second time through the fixing plate 15. The resin grinding wheel 4 of the device is tightened and fixed for the second time, so that the resin grinding wheel 4 is prevented from loosening when the grinder 1 is in use, which increases practicality and reduces the failure rate.

[0041] Furthermore, when the device is used, when the two sliding posts 11 move, since the sliding posts 11 are cylindrical in shape, they are limited by two limit blocks 13 set on the outer surface of the sliding posts 11 to avoid displacement when the sliding posts 11 move, causing the connecting holes 14 on the sliding posts 11 to be offset, thereby avoiding the inconvenience of fixing when plugging in the connecting posts 16, thereby increasing practicality.

[0042] Working principle: When using the device, when the grinder 1 is used for a long time and a new resin grinding wheel 4 needs to be installed, the resin grinding wheel 4 is manually picked up, the two first slide grooves 7 on the resin grinding wheel 4 are aligned with the corresponding fixed blocks, and then the resin grinding wheel 4 is moved so that the two fixed blocks 9 slide into the interior of the resin grinding wheel 4. When the two fixed blocks 9 slide into the interior of the resin grinding wheel 4, the two first slide grooves 7 squeeze the corresponding slide posts 11, and the movement of the two slide posts 11 compresses the corresponding springs 12. Then, when the two slide posts 11 pass through the first slide grooves 7, the two slide posts 1 1 returns to its original position under the automatic reset characteristic of the corresponding spring 12, so that the resin grinding wheel piece 4 can be simply installed. The use of the device can quickly install the resin grinding wheel piece 4 through the limit of the two sliding columns 11. After the resin grinding wheel piece 4 is simply installed, it is necessary to fasten and fix the resin grinding wheel piece 4. Pick up the fixing plate 15, plug it with the corresponding connecting holes 14 through the two connecting columns 16, and then pick up the bolt 18. The bolt 18 passes through the connecting groove 17 and the through hole 6 and is threadedly connected with the thread groove 8, and then the resin grinding wheel piece 4 is fixed for a second time. The resin grinding wheel piece 4 is convenient to install and use.
