Because the first water pipe 9 and the second water pipe 11 are directly exposed in the air, the cooling water continuously exchanges heat with the air in the circulating flowing process, so that the temperature of the cooling water is not gradually increased by taking away the heat of the oil cylinders 1-3. For the water pipe with longer length, the water pipe can be fixed on the sewing machine shell 1 by a U-shaped clamp 10 to ensure the integral aesthetic degree of the machine, as shown in figure 1, a first water pipe 9 is fixed on the sewing machine shell 1 by the U-shaped clamp 10.
