Although this type of grinding brush has the effect of facilitating the replacement of the bristles, it is lacking in the ability to adjust the angle of the bristles. Since this type of grinding brush does not have a structure for adjusting the angle of the bristles, this will result in the curved surface not being able to be ground evenly when grinding an object with a curvature, which requires the staff to replace the grinding brush with one that matches the curvature of the object, thereby reducing the adaptability of the grinding brush. Utility Model Content

The outer annular plate 3 and the inner annular plate 4 are both provided with bristles 9, rotating rod 6, torsion spring 7 and connecting rod 8. The design of the torsion spring 7 and the rotating rod 6 makes it easy to adjust the angle of the bristles 9, thereby facilitating the grinding of objects with different curvatures, thereby improving the adaptability of the grinding brush.

[0025] Embodiment 2

[0026] See also Figure 1-4 A slot 10 is provided on the surface of the fixed plate 1, and an insert plate 11 is inserted inside the slot 10. An outer sleeve 12 is fixedly installed on the surface of the insert plate 11. The design of the outer sleeve 12 has the effect of protecting the bristles 9. The outer sleeve 12 is slidingly connected to the fixed plate 1, and the bottom of the outer sleeve 12 is rotatably connected to a bottom plate 13, and the bottom plate 13 and the outer sleeve 12 are connected by threads. The threaded connection design of the bottom plate 13 and the outer sleeve 12 facilitates the opening and closing of the bottom plate 13, and a ring gasket 14 is fixedly installed on the surface of the bottom plate 13, and the ring gasket 14 is slidingly connected to the outer sleeve 12.

[0027] Working principle: when it is necessary to grind a curved object, the torsion spring 7 will drive the connecting rod 8 to rotate through the rotating rod 6. When the connecting rod 8 rotates, it will drive the inner annular plate 4 to move, so that the bristles 9 are attached to the surface of the curved object through the inner annular plate 4. When the fixed plate 1 is pressed, the fixed plate 1 will attach the bristles 9 to the surface of the object through the outer annular plate 3 and the inner annular plate 4. When the bristles 9 need to be replaced, it is only necessary to rotate the rotating block 2. After the rotating block 2 is turned away from the fixed rod 5, the fixed plate 1 can be taken out from the fixed rod 5. The fixed plate 1, the fixed rod 5, the rotating block 2, the outer annular plate 3, the inner annular plate 4, the rotating rod 6, the torsion spring 7 and the connecting rod 8 make it easy to adjust the angle of the grinding brush, thereby playing a role. In order to facilitate the grinding of objects with different curvatures and avoid the situation where the grinding brush cannot grind objects with curvatures, when the grinding brush needs to be stored, the outer sleeve 12 only needs to be sleeved on the surface of the fixed plate 1, and the outer sleeve 12 will drive the plug plate 11 to be inserted into the slot 10, and then the bottom plate 13 is connected to the outer sleeve 12 through a thread, and the bottom plate 13 will drive the ring gasket 14 to slide into the inside of the outer sleeve 12, and the storage of the grinding brush can be completed at this time. The slot 10, the plug plate 11, the outer sleeve 12, the bottom plate 13 and the ring gasket 14 make it easy to store the grinding brush, thereby avoiding the situation where the bristles 9 are rusted due to water stains, and also avoiding the situation where the bristles 9 injure the staff.
