The adsorption component 57 is arranged on the side of the oil pipe 54 near the external thread 55.

[0026] By adopting the above technical solution, the connecting frame 51 fixes the fixing plate 52 and the winding roller 53 to the oil tank body 1. The oil pipe 54 is a plastic pipe that can be wound around the winding roller 53. When it is not necessary to extend the oil spraying device 3, the oil pipe 54 can be stored. When it is necessary to extend the oil spraying device 3, the nozzle 4 is unscrewed from the external thread 10, and one end of the internal thread 56 of the oil pipe 54 is screwed into the external thread 10, thereby connecting the oil pipe 54 and the oil spraying device 3. The nozzle 4 is connected to the other end of the oil pipe 54 through the internal thread 12. The oil sprayed by the oil spraying device 3 will enter the nozzle 4 from the oil pipe 54 and then be sprayed from the nozzle 4 to various corners of the lathe.
