[0028] Working principle: When using this device, first adjust the position of the nozzle 205 to prevent it from obstructing the polishing head 5. Loosen the bolt 210 by unscrewing it from the threaded hole 212. This separation of the bolt 210 from the threaded hole 212 causes the adjusting plate 209 to lose its limit position. The adjustment plate 209 can then be moved. This movement of the adjusting plate 209 moves the L-shaped rod 208, which in turn moves the L-shaped plate 203 within the groove 202. 03. The movement inside the chute 202 drives the annular hollow tube 204 to move, and the movement of the annular hollow tube 204 drives the nozzle 205 to move. When the nozzle 205 moves to the appropriate position, the bolt 210 is screwed into the corresponding threaded hole 212 again to fix the position of the adjusting plate 209. When the position of the nozzle 205 is adjusted, the external water supply equipment can be connected through the water inlet pipe 207 to supply water to the water inlet pipe 207, hose 206 and annular hollow tube 204, and through the annular... The nozzle 205 on the hollow tube 204 sprays water towards the polishing head 5. Simultaneously, the power cord 10 connects to an external power supply. Pressing the start / stop button 7 starts the motor, which drives the rotating rod 4 to rotate, thereby rotating the polishing head 5 to polish the model. At this time, the water sprayed from the nozzle 205 can be used to cool the polishing head 5, preventing overheating and damage caused by friction between the polishing head 5 and the model. This improves the lifespan of the device and increases polishing efficiency. During use, the rotating wheel 36 can also be rotated. The rotation of the rotating wheel 36 drives the threaded rod 35 to rotate. The rotation of the threaded rod 35 drives the movable plate 39 to move downward on the surface of the upright 38. The downward movement of the movable plate 39 on the surface of the upright 38 drives the arc-shaped clamping ring 33 to move downward on the surface of the vertical rod 32. The downward movement of the arc-shaped clamping ring 33 on the surface of the vertical rod 32 clamps and fixes the water inlet pipe 207 inside the arc-shaped bracket 31, thereby using the arc-shaped bracket 31 to support the water inlet pipe 207 and prevent the water inlet pipe 207 from dragging on the ground.
