[0057] The upper end of the extended metal tube 33 is inserted into the built-in cavity 3 and fixedly connected to the rotating plate 32 , and the interior of the extended metal tube 33 is communicated with the interior of the built-in cavity 3 .

[0058] The opening and closing assembly 6 includes an arc-shaped ring 61, a hollow tube 63, a flat airbag 64, an annular rubber 65, a circular plate 66, a dredging rod 67, a cylindrical bag 68, a metal vertical sheet 69, a transverse spring 601 and a metal weighted ball 602;

[0059] The arc-shaped ring 61 is welded to the outside of the extended metal tube 33 , and a side hole 62 connected to the interior is opened on the outer wall of the extended metal tube 33 . The side hole 62 is located on the inner side of the arc-shaped ring 61 , and the flat airbag 64 , annular rubber 65 and circular plate 66 are located inside the extended metal tube 33 .

[0060] The flat airbag 64 is located at the upper end of the side hole 62, the annular rubber 65 is fixedly installed on the outer side of the flat airbag 64, the circular plate 66 is located at the lower end of the flat airbag 64, the dredging rod 67 is welded on the side wall of the circular plate 66, and the dredging rod 67 is inserted into the side hole 62. By setting the hollow tube 63 and the dredging rod 67, vibration is bound to occur during the movement of the opening and closing component 6, and the hollow tube 63 and the side hole 62 will not be blocked, thereby achieving a better dredging effect and extending the service life of the grinder 1. The hollow tube 63 is vertically inserted into the upper end of the circular plate 66, and the hollow tube 63 penetrates the flat airbag 64, and the interior of the hollow tube 63 is connected with the interior of the flat airbag 64. By providing the flat airbag 64 and the annular rubber 65, water is injected into the water inlet 11, and the transverse spring 601 squeezes the cylindrical bag 68 to expand the flat airbag 64. The annular rubber 65 squeezes the inner wall of the extended metal tube 33, and the water in the extended metal tube 33 will not flow out along the side hole 62, thereby achieving the purpose of saving water.

[0061] The cylindrical capsule 68 is fixedly installed on the upper end of the hollow tube 63, and the interior of the cylindrical capsule 68 is connected to the interior of the hollow tube 63. The upper and lower sides of the cylindrical capsule 68 are folded, and the cylindrical capsule 68 is located between the four pillars 5. The metal vertical sheet 69 is fixedly installed on the outer wall of the cylindrical capsule 68. One end of the transverse spring 601 is fixedly connected to the metal vertical sheet 69, and the other end of the transverse spring 601 is welded to the pillar 5.

When not in use, the water in the extended metal tube 33 will not flow out along the side hole 62, thereby achieving the purpose of saving water.

[0063] Then, the built-in motor 4 works to drive the support 5 and the extended metal tube 33 to rotate, and at the same time, the opening and closing component 6 is subjected to the centrifugal force, so that the cylindrical capsule 68 and the metal weight ball 602 outside the cylindrical capsule 68 are subjected to the centrifugal effect, and the transverse spring 601 is subjected to a greater centrifugal force, thereby achieving a greater squeezing effect, so that the cylindrical capsule 68 is expanded, and the flat airbag 64 is contracted, so that the water in the side hole 62 flows out, and the purpose of dust reduction is achieved;

[0066] Secondly, when grinding, the lower end of the grid 28 is in contact with the stone and squeezed, and the arc-shaped metal 25 is easily deformed by the squeezing, so as to avoid affecting the grinding of the metal ball 34. At the same time, the dust generated by grinding is mixed with water to make the water-cement adhere to reduce the dust, and at the same time, the large particles of dust can be blocked in the grid 28 to avoid harm to the operator;

[0067] When cleaning the protective assembly 2, push the arc metal 25 upward to squeeze the squeezing spring 24 and make the built-in rod 29 contact the vertical rod 201, then rotate the annular cover 21 to make the built-in rod 29 and the vertical rod 201 staggered and squeezed, so that the arc metal 25 vibrates, thereby cleaning the impurities on the surface of the grid 28 to avoid affecting the line of sight.

[0069] like Figure 7 As shown, a method for using a carving device based on handicraft art includes the following steps:

[0070] Step 1: the built-in motor 4 works, the opening and closing assembly 6 is acted upon by centrifugal force, the cylindrical bag 68 expands, and the flat air bag 64 contracts, causing the water in the side hole 62 to flow out, thereby achieving the purpose of dust reduction;

[0071] Step 2: During the movement of the opening and closing component 6, vibration is bound to occur, and the hollow tube 63 and the side hole 62 will not be blocked, thereby achieving a better dredging effect and extending the service life of the grinder 1;

[0072] Step 3: The metal ball 34 is connected to the extended metal tube 33, and the heat can be absorbed by the water inside, thus reducing the frictional heat;
