The size of the abrasive tool can be adjusted according to needs, which is convenient to use and achieves the effect of facilitating the adjustment of the size of the abrasive tool. The end of the second connecting rod 8 away from the first connecting rod 5 is hinged to one side of the threaded sleeve 13, and a slide groove 14 is opened on one side of the threaded sleeve 13, and the slide groove 14 is located above the second connecting rod 8. The slide groove 14 is slidably connected to one side of the support plate 15, and the support plate 15 is fixedly connected to the bottom of the cover plate 17 through a spring 16 fixedly connected to the top thereof. The top of the cover plate 17 is fixedly connected to the bottom of the connecting pipe 18, and the bottom of the cover plate 17 is fixed to the top of the protective cover 19 The protective cover 19 is made of plastic and is round. The size of the protective cover 19 is just enough to cover the abrasives and grinding tools, which is beneficial to improving the dust removal effect. The connecting pipe 18 is connected to the external dust suction device, and the cover plate 17 and the protective cover 19 are provided with a pipeline connected to the connecting pipe 18. One side of the inner wall of the protective cover 19 is fixedly connected to one side of the dust suction port 20. The dust suction port 20 is connected to the connecting pipe 18, and the side of the dust suction port 20 away from the protective cover 19 is inclined downward. The dust suction port 20 is connected to the connecting pipe 18 by the connecting pipe 18 provided in the protective cover 19 and the cover plate 17, so that the suction force in the connecting pipe 18 can be transmitted to the dust suction port 20, so as to achieve the purpose of dust suction. The bottom of the protective cover 19 is fixedly connected to the top of the rubber strip 21.A vent hole 22 is provided on the side of the rubber strip 21 away from the second connecting rod 8. The rubber strip 21 is distributed along the entire circle of the protective cover 19. A cavity is provided inside the rubber strip 21. When in use, the rubber strip 21 is squeezed together with the surface of the object. The vent hole 22 can discharge the air in the cavity inside the rubber strip 21, thereby increasing the contact area between the rubber strip 21 and the surface of the object, thereby increasing the friction between the bottom of the protective cover 19 and the surface of the object, thereby achieving the effect of keeping the protective cover 19 stable.

When pressing down for grinding, the bottom of the protective cover 19 first contacts the material surface, and when the first fixed seat 1 contacts the material surface, the spring 16 is stretched, driving the protective cover 19 to press against the material surface. At the same time, the connecting pipe 18 transmits the suction force of the external dust suction device to the dust suction port 20, so that the abrasive tool cover can be set in the protective cover 19 and the debris generated when the abrasive tool is working can be absorbed, achieving the effect of dust removal. The device can flexibly adjust the size and has the function of dust collection, solving the problem of the single function of the existing abrasive tool.

[0020] When in use, the abrasive tool can be pulled out by using the spring 16 fixedly connected to the top of the support plate 15, and then the first connecting rod 5 hinged on the top of the second fixed seat 3 and the second connecting rod 8 hinged to the first connecting rod 5 are used, in conjunction with the first buckle 9 and the clamp 10 respectively fixedly connected to the first connecting rod and the second connecting rod 8, to adjust the size of the abrasive tool as needed, finally, the cover plate 17 fixedly connected to the top of the spring 16 and the connecting pipe 18 fixedly connected to the top of the cover plate 17 are used, in conjunction with the dust suction port 20 fixedly connected on the inner wall of the cover plate 17 and the rubber strip 21 fixedly connected to the bottom of the cover plate 17, to connect the connecting pipe 18 with the external dust suction device, and the abrasive tool cover is set in the protective cover 19 to absorb the debris generated when the abrasive tool is working.
