[0023] Specifically, the cooling device 6 includes a sliding sleeve 61, and there are two sliding sleeves 61. The two sliding sleeves 61 are fixedly connected to the surface of the precision carving body 3. The inner wall of the sliding sleeve 61 is slidably connected to a moving frame 62, and the inner wall of the moving frame 62 is rotatably connected to a nozzle 63. The rotating end of the nozzle 63 is fixedly connected to a gear 67. The surface of the moving frame 62 is fixedly connected to a cylinder 610, and the output end of the cylinder 610 is fixedly connected to a control drive member 66, and the drive member 66 is meshed with the gear 67. The surface of the nozzle 63 is fixedly connected to a hose 65, and one end of the hose 65 is connected to the water inlet valve 5. A limiting component 69 is provided on the surface of the moving frame 62, and an auxiliary component 64 is provided on the surface of the precision carving body 3.

[0024] In this embodiment: when cooling is performed, the water inlet valve 5 supplies water to the hose 65, and the nozzle 63 sprays out water to dissipate heat. Then, the cylinder 610 is opened, and the cylinder 610 drives the driving member 66 to move. The driving member 66 drives the gear 67 and the nozzle 63 to rotate, so that the nozzle 63 can spray water on the entire blade body 4 to dissipate heat, thereby improving the heat dissipation effect.

[0025] Specifically, two slide columns 68 are fixedly connected to the surface of the movable frame 62, and the driving member 66 is slidably connected to the surface of the slide columns 68. When the driving member 66 is in use, the slide columns 68 can improve the stability of the driving member 66 when it moves.

[0026] Specifically, the auxiliary component 64 includes a water inlet sleeve 641, which is sleeved on the surface of the precision carving body 3. A water inlet pipe 642 is installed on the surface of the water inlet valve 5. One end of the water inlet pipe 642 is connected to the water inlet sleeve 641. One end of the water inlet sleeve 641 is fixedly connected to a water outlet pipe 643. When the water inlet valve 5 is supplying water, part of the water can be transported to the water inlet sleeve 641 through the water inlet pipe 642.

A plurality of clamping grooves are provided on the surface of the sliding sleeve 61, and the clamping block 691 is clamped to the inner wall of the clamping groove.

[0030] Specifically, a pull rod 693 is fixedly connected to the surface of the clamping block 691 , and the pull rod 693 is slidably connected to the inner wall of the movable frame 62 .

[0031] In this embodiment, the pull rod 693 is pulled to conveniently control the movement of the block 691 .

[0032] Working principle: when the engraving body 3 drives the cutter body 4 to rotate, water is supplied to the two hoses 65 and the water inlet pipe 642 respectively through the water inlet valve 5. The hose 65 can input water into the nozzle 63 and spray it out to dissipate heat to the cutter body 4. At the same time, the water inlet pipe 642 can input water into the water inlet jacket 641. The heat absorbed by the water inlet jacket 641 can take away part of the water, thereby dissipating heat to the engraving body 3. At the same time, when the nozzle 63 sprays water, it can drive the cylinder 610, and the cylinder 610 drives the driving member 66 to move, and the driving member 66 drives the gear 67 and the nozzle 63 to rotate. After rotating to a certain position, it can stop spraying water, and then adjust it so that the nozzle 63 can spray water to dissipate heat on the entire cutter body 4. The two groups of nozzles can be adjusted synchronously or asynchronously to spray water, thereby achieving cooling treatment.
