[0002] The carving of wooden special-shaped parts often uses techniques such as relief, sunken carving and openwork carving. There are many types and quantities of wooden special-shaped parts, such as wood carvings, toys, furniture components and other wooden components. These special-shaped parts need to be polished after carving, and a polishing device is needed at this time.

[0003] In the prior art, due to the different shapes of special-shaped parts, they cannot be picked up with one hand and polished with a polishing motor with the other hand like conventional workpieces. Therefore, they can only be clamped and fixed with a clamp. However, the clamp of this polishing device is usually fixed, so it is inconvenient to polish the irregular positions and corners of the special-shaped parts. Therefore, it is necessary to design a surface polishing device for special-shaped parts to solve the above problem. Utility Model Content

The first gear 3 is meshed with the second gear 4. The teeth and meshing details of the two are not shown in the figure, but the two are actually meshed. A control console 20 is provided on the mounting disk 1.

[0022] In the utility model, the upper end of the mounting plate 6 is fixedly connected to a limit frame 12, and the limit frame 12 is slidably connected to the side wall of the grinding motor 13, so that the grinding motor 13 can be limited, so that the grinding motor 13 has a special placement position to avoid the grinding motor 13 being placed randomly.

[0023] In the utility model, an air compressor 21 is provided on the mounting plate 6, and an air outlet end of the air compressor 21 is connected to a jet gun 23 through a connecting pipe.
