[0022] Embodiment 3

[0023] On the basis of Embodiment 2, in order to make the movement of the support seat 6 more stable, two hydraulic cylinders 13 are provided. The bottom surface of the hydraulic cylinder 13 is fixedly connected to the top surface of the water tank 1, and the hydraulic cylinders 13 are respectively at the centers of the front and rear ends of the water tank 1. The movable end of the hydraulic cylinder 13 is fixedly connected to the bottom surface of the support seat 6. The support seat 6 is between the fixed frames 7.

The support seat 6 drives the guide rod 14 to slide in the guide groove 15. The hydraulic cylinder 13 ensures the stability of the front and rear ends of the support seat 6. Under the action of the guide rod 14 and the guide groove 15, the stability of the left and right ends of the support seat 6 is ensured, so that the movement of the support seat 6 is more stable, and thus the problem that the cooling and cooling cannot be directly carried out at other positions is solved, and the cooling and cooling can be directly carried out at other positions.

[0024] Embodiment 4

[0025] Refer to the appendix Figure 1 and Figure 3 Referring to the appendix, on the basis of Embodiment 2, this embodiment adds a support assembly. An annular groove 11 is opened on the top surface of the support seat 6, and the center of the annular groove 11 and the center of the support seat 6 are on the same vertical line. The inner wall of the annular groove 11 is movably connected with a support rod 12. There are four support rods 12. The support rods 12 are perpendicular to the support seat 6. The upper ends of the support rods 12 are fixedly connected to the bottom surface of the movable disk 10 and are perpendicular to the movable disk 10. The support rods 12 are ninety degrees apart from each other with the center of the movable disk 10 as the center; When the movable disk 10 rotates, the rotating disk 10 drives the support rod 12 to slide in the annular groove 11. Since the rotating disk 10 is only supported by the rotating shaft 18 below, the overall device may be unstable. Therefore, the support rod 12 and the annular groove 11 are provided to support the rotating disk 10 to make it more stable, thereby solving the problem that direct cooling and temperature reduction cannot be carried out at other positions, and direct cooling and temperature reduction can be carried out at other positions.

[0026] Embodiment 5

The turntable 17 drives the eccentric column 19 to make the movable block 27 move in the movable groove 26, and then drives the strip-shaped rod 23 to make the swing fan 22 swing. The swing fan 22 drives the gear 20 to rotate back and forth, and then drives the movable disk 10 to rotate back and forth by driving the rotating shaft 18. At the same time, start the water pump 4 to pump water out of the water tank 1 through the water suction pipe 2 and discharge it from the drain pipe 5 to cool and lower the temperature at the connection between the drill bit 8 and the object.
