[0013] (3) Beneficial effects

[0014] Compared with the prior art, the present invention provides a sandpaper fixing device for sandpaper polishing, which has the following beneficial effects:

[0015] The sandpaper fixing device for sandpaper polishing comprises a fixing seat and a sandpaper body which are inserted into a fixing sleeve. At this time, the fixing sleeve squeezes the peripheral side of the sandpaper body. At this time, there is a large friction between the fixing sleeve and the peripheral side of the sandpaper body, thereby providing an upward force to the peripheral side of the sandpaper body, which can make the sandpaper body lay tighter on the bottom of the fixing seat. The fixing sleeve is rotated so that the fixing sleeve cooperates with the threaded teeth to be fixed on the fixing seat, which can make the sandpaper body fixed on the fixing seat more firmly.

[0016] Tighten the limit rods in sequence so that the limit rods provide a limiting effect on the sandpaper body again, which can further make the sandpaper installed more firmly on the fixed seat and prevent the sandpaper from slipping, thereby improving the polishing efficiency of the workpiece.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 The utility model relates to a sandpaper fixing device for sandpaper grinding, comprising a fixing seat 1 and a fixing sleeve 5. A positioning shaft 2 is fixedly arranged on the upper end of the fixing seat 1. A sandpaper body 3 is placed on the bottom of the fixing seat 1. A threaded tooth 4 is provided on the top of the fixing seat 1. The fixing sleeve 5 can be penetrated by the fixing seat 1 and the sandpaper body 3, and the top of the fixing sleeve 5 is threadedly connected to the threaded tooth 4. The fixing sleeve 5 can squeeze the peripheral side of the sandpaper body 3 at the outer wall of the fixing seat 1. A plurality of limiting seats 7 and limiting rods 6 are provided on the peripheral side of the fixing sleeve 5. The limiting rod 6 can penetrate the limiting seat 7 and the fixing sleeve 5, and one end of the limiting rod 6 can contact the sandpaper body 3. The limiting rod 6 is threadedly matched with the limiting seat 7.

[0023] In this embodiment, the sandpaper body 3 is laid on the bottom of the fixing base 1, and the fixing base 1 is taken. Specifically, glue can be applied to the bottom of the fixing base 1 to preliminarily fix the sandpaper body 3 on the bottom of the fixing base 1. Then, the fixing sleeve 5 is taken and placed on a designated table, so that the fixing base 1 and the sandpaper body 3 are inserted into the fixing sleeve 5. At this time, the fixing sleeve 5 will squeeze the peripheral side of the sandpaper body 3. At this time, there will be a large friction between the fixing sleeve 5 and the peripheral side of the sandpaper body 3, which will provide an upward force to the peripheral side of the sandpaper body 3. The sandpaper body 3 can be laid more tightly on the bottom of the fixing seat 1, and the fixing sleeve 5 can be rotated so that the fixing sleeve 5 and the threaded teeth 4 are fixed on the fixing seat 1. Finally, the limiting rods 6 are tightened in sequence so that the limiting rods 6 provide a limiting effect on the sandpaper body 3 again, which can make the sandpaper installed on the fixing seat 1 more firmly and prevent the sandpaper from slipping off, thereby improving the polishing efficiency of the workpiece. When the sandpaper body 3 is disassembled, multiple limiting rods 6 can be loosened and the fixing sleeve 5 can be rotated in the opposite direction, so that the sandpaper body 3 can be easily replaced.

[0024] Furthermore, the plurality of limiting seats 7 are all fixed on the bottom of the fixing sleeve 5 .

[0025] In this embodiment, a plurality of toggle blocks 8 located on the outer wall of the fixing sleeve 5 are fixedly provided on the top of the fixing sleeve 5. The toggle blocks 8 can provide a force point for the fixing sleeve 5, making it easy to install and disassemble the fixing sleeve 5.

[0026] In this structure, an annular groove 9 is provided at the bottom of the fixing base 1, and an adhesive strip 10 is fixedly arranged inside the annular groove 9. The peripheral side of the sandpaper body 3 can be bonded by the adhesive strip 10 after being bent. When the peripheral side of the sandpaper body 3 is squeezed, it will contact the adhesive strip 10, so that it can be bonded to the peripheral side of the fixing base 1, which can further limit the peripheral side of the sandpaper body 3.

[0027] In this embodiment, a fixing ring 11 is fixedly provided at the bottom of the fixing sleeve 5, and a plurality of fan blades 12 are provided at the lower end of the fixing ring 11. The positioning shaft 2 can be fixed on the rotating shaft of the output end of the handheld motor. Specifically, a coupling can be used for docking. When the fixing seat 1 rotates, the fixing ring 11 can drive the plurality of fan blades 12 to rotate, which can provide a blowing function for the polishing part of the sandpaper, and can prevent impurities after polishing from remaining on the workpiece, thereby improving the functionality of this structure.

[0028] Furthermore, the present invention is improved in that the fixing seat 1 and the threaded teeth 4 are both made of aluminum alloy.
