Through the arrangement of the noise reduction pad 7, the grinding wheel 6 and the mounting base 1 can be spaced apart to reduce noise.
[0023] See also Figure 1 , Figure 2 , Figure 3The side of the mounting base 1 is fixedly connected with a slide rail 8, and the inner side of the slide rail 8 is slidably connected with a convex slider 9. The inner side of the slide rail 8 is provided with a slide groove, and the slide groove is in a convex shape. The convex slide groove is provided to facilitate the sliding of the convex slider 9 and also has a limiting function. The end of the convex slider 9 located outside the slide rail 8 is fixedly connected with an insert block 10, and the side of the grinding wheel 6 is fixedly connected with an insert sheet 11, and the vertical part of the insert sheet 11 is fixedly connected with a metal spring sheet 12, and the insert sheet 11 is plugged with the insert block 10, and the metal spring sheet 12 is clamped with the insert block 10.
[0024] See also Figure 3 The plug block 10 is slidably connected with a push pin 13, one end of which contacts the metal spring sheet 12, and the other end of which is fixedly connected with a button 14.

[0025] The specific implementation process of the utility model is as follows: when in use, first place the noise reduction pad 7 on the upper end of the grinding wheel 6, and put it on the outside of each collision block 16, then place the grinding wheel 6 on the lower protection of the mounting base 1, and insert the insert 11 on the grinding wheel 6 into the insert block 10, and the metal spring 12 on the insert 11 will be stuck inside the insert block 10 after deformation, so that the installation of the grinding wheel 6 is completed;
[0026] When the mounting base 1 is driven to rotate by the driving mechanism, the grinding wheel 6 is attached to the surface of the object. The grinding wheel 6 is relatively still at first, while the shock-absorbing seat 2 at the bottom of the mounting base 1 continues to rotate, and then the shock-absorbing block 4 hits the impact block 16. Since the shock-absorbing block 4 is subjected to the reaction force from the impact block 16, the damping rod 3 is driven to move relative to the shock-absorbing seat 2.

There is a well-harmonized buffer area between the grinding wheel 6 and the mounting base 1, which not only reduces the vibration caused by the impact between the two, but also reduces the impact deformation between the grinding wheel 6 and the object, thereby improving the service life of the grinding wheel 6.
